Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Accounting Policies The condensed consolidated financial statements include the accounts of Matrix Service Company (“Matrix”, “we”, “our”, “us”, “its” or the “Company”) and its subsidiaries, unless otherwise indicated. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. The information furnished reflects all adjustments, consisting of normal recurring adjustments and other adjustments described herein, that are, in the opinion of management, necessary for a fair statement of the results of operations, cash flows and financial position for the interim periods presented. The accompanying condensed financial statements should be read in conjunction with the audited financial statements for the year ended June 30, 2015 , included in the Company’s Annual Report on Form 10-K for the year then ended. The results of operations for the nine month period ended March 31, 2016 may not necessarily be indicative of the results of operations for the full year ending June 30, 2016. Recently Issued Accounting Standards Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The ASU also requires entities to disclose both quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The ASU's disclosure requirements are significantly more comprehensive than those in existing revenue standards. The ASU applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification ("ASC"). In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. With the deferral, this ASU is now effective for annual reporting periods beginning after December 15, 2017, with early adoption now permitted on a limited basis. Upon adoption, the Company may elect one of two application methods, a full retrospective application or a modified retrospective application. We expect to adopt this standard on July 1, 2018 and are currently evaluating its expected impact on our financial statements. Accounting Standards Update 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments On September 25, 2015, the FASB issued ASU 2015-16 to simplify the accounting for measurement-period adjustments. The ASU was issued in response to stakeholder feedback that restatements of prior periods to reflect adjustments made to provisional amounts recognized in a business combination increase the cost and complexity of financial reporting but do not significantly improve the usefulness of the information. Under the ASU, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The ASU also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. We expect to adopt this standard on July 1, 2016. Accounting Standards Update 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes On November 20, 2015, the FASB issued ASU 2015-17, which will require entities to present deferred tax assets ("DTAs") and deferred tax liabilities ("DTLs") as noncurrent in a classified balance sheet. The ASU simplifies the current guidance, which requires entities to separately present DTAs and DTLs as current and noncurrent in a classified balance sheet based on the classification of the related asset or liability. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2016, and interim periods within those years with early adoption permitted. The Company has elected to retrospectively early adopt ASU 2015-17, effective for the quarter ended December 31, 2015. The quantitative effects of the change on the prior balance sheet presented, for the fiscal year ended June 30, 2015, resulted in a net reclassification of $6.6 million and $6.6 million from the "Deferred income taxes" current asset and liability financial statement line items, respectively, to the "Deferred income taxes" asset and liability financial statement line items included in the noncurrent asset and liability sections of the balance sheet. Accounting Standards Update 2016-02, Leases (Topic 842) On February 25, 2016, the FASB issued ASU 2016-02. The amendments in this update require, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We expect to adopt this standard on July 1, 2019 and are currently evaluating its expected impact on our financial statements. Accounting Standards Update 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting On March 30, 2016, the FASB issued ASU 2016-09, which simplified several aspects of accounting for stock-based compensation transactions, including the accounting for income taxes and forfeitures and statutory tax withholding requirements. The ASU is effective for the Company on July 1, 2017 and early adoption is permitted. The Company is currently evaluating whether it will early adopt the ASU. The following is a description of the key provisions of the ASU, its transition requirements and its estimated impacts on the Company's financial statements: Accounting for Income Taxes : The amendments require the Company to recognize excess tax benefits or tax deficiencies in its provision for income taxes in its consolidated statements of income during the period of vesting or exercise of its nonvested deferred share awards and stock options, respectively, for which it expects to receive an income tax deduction. Currently, the Company recognizes any excess tax benefits in additional paid-in capital ("APIC") in the balance sheet and any tax deficiencies are recognized as a reduction of APIC to the extent the Company has accumulated excess tax benefits. Any tax deficiencies in excess of accumulated excess tax benefits in APIC are recognized in the provision for income taxes. The amendments also require the Company to only present excess tax benefits and tax deficiencies in the operating section of its statements of cash flows. Currently, the Company is required to present such items in both the financing section and operating section of its statements of cash flows. Amendments to the presentation of excess tax benefits and tax deficiencies in the statements of cash flows may be applied retrospectively or prospectively. The Company has not yet determined how it will apply these amendments. Amendments requiring the recognition of excess tax benefits and tax deficiencies in income are to be applied prospectively. The Company cannot reasonably estimate the future impacts of these amendments to its financial statements since such impacts are primarily dependent on the Company's stock price on the dates of future vestings or exercises. The Company's stock price may vary significantly over time and such variability may result in material income tax impacts to income upon future vestings and exercises. The Company is required to apply the amendments for accumulated excess tax benefits on a modified retrospective basis as a cumulative-effect adjustment to retained earnings as of the date of adoption. The balance of accumulated excess tax benefits included in APIC was $9.8 million as of March 31, 2016. Accounting for Forfeitures : The Company currently recognizes expense on all stock-based awards over the requisite service period, net of estimated forfeitures. The amendments in this ASU allow the Company to elect, as a company-wide accounting policy, either to continue to estimate the amount of forfeitures to exclude from compensation expense or to exclude forfeitures from compensation expense when they occur. If the Company elects to account for forfeitures when they occur, it will apply the accounting change on a modified retrospective basis as a cumulative-effect adjustment to retained earnings as of the date of adoption. The Company does not expect these amendments to have a material impact to its financial statements if it does elect to account for forfeitures when they occur. The Company has not yet determined how it will account for forfeitures upon adoption of the ASU. Statutory Tax Withholding Requirements : Currently, an entire award must be classified as a liability if the fair value of the shares withheld exceeds the Company's minimum statutory withholding obligation. Under the ASU, the Company will be allowed to withhold shares with a fair value up to the amount of tax owed using the maximum statutory tax rate in the employee's applicable jurisdictions. The Company will be allowed to determine one maximum rate for all employees in each jurisdiction, rather than a rate for each employee in the jurisdiction. Also, the ASU requires that cash outflows to reacquire shares withheld for taxes to be classified in the financing section of its statements of cash flows. Since the Company does not have any awards classified as liabilities due to statutory tax withholding requirements as of March 31, 2016, and since the Company already presents its cash outflows for reacquiring shares withheld for taxes as a financing activity in its statements of cash flows, the Company does not expect these amendments to have any impact on its financial statements.

Acquisitions	Note 2 – Acquisition Purchase of HDB Ltd. Limited Partnership On August 22, 2014 , the Company purchased substantially all of the assets of HDB Ltd. Limited Partnership ("HDB"). HDB, headquartered in Bakersfield, California provides construction, fabrication and turnaround services to energy companies throughout California’s central valley. The acquisition advances a strategic goal of the Company to expand into the upstream energy market. The acquisition purchase price was $5.6 million and was funded with cash on hand. Commencing on August 22, 2014, HDB's operating results are included in the Oil Gas & Chemical Segment. The purchase price was allocated to the major categories of assets and liabilities based on their estimated fair value at the acquisition date. The following table summarizes the purchase price allocation (in thousands): Current assets $ 1,645 Property, plant and equipment 1,001 Tax deductible goodwill 3,065 Other intangible assets 900 Total assets acquired 6,611 Current liabilities 1,060 Net assets acquired $ 5,551 All of the recorded goodwill from the HDB acquisition is tax deductible. The operating data related to this acquisition was not material. Purchase of Baillie Tank Equipment, Ltd. On February 1, 2016 , the Company completed the acquisition of all outstanding stock of Baillie Tank Equipment, Ltd. (“BTE”) , an internationally-based company with nearly 20 years of experience in the design and manufacture of products for use on aboveground storage tanks. Founded in 1998, BTE is a provider of tank products including geodesic domes, aluminum internal floating roofs, floating suction and skimmer systems, roof drain systems, and seals. BTE is headquartered in Sydney, Australia with a manufacturing facility in Seoul, South Korea. The Company acquired BTE to expand its service offerings of certain technical solutions for aboveground storage tanks. The business is now known as Matrix Applied Technologies, and its operating results are included in the Storage Solutions segment. The Company purchased BTE with cash on-hand for a net purchase price of $13.0 million . The Company paid $15.4 million when including the subsequent repayment of long-term debt acquired and the settlement of certain other liabilities acquired, and excluding the cash acquired and certain amounts owed to the former owners for working capital adjustments. The net purchase price was allocated to the major categories of assets and liabilities based on their estimated fair value at the acquisition date. The following table summarizes the preliminary net purchase price allocation (in thousands): Current assets $ 4,526 Property, plant and equipment 4,347 Goodwill 7,618 Other intangible assets 720 Other assets 84 Total assets acquired 17,295 Current liabilities 1,048 Deferred income taxes 341 Long-term debt 1,858 Other liabilities 407 Net assets acquired 13,641 Cash acquired 592 Net purchase price $ 13,049 The goodwill recognized from the acquisition is attributable to the synergies of combining our operations and the technical expertise of the acquired workforce. None of the goodwill recognized is expected to be deductible for income tax purposes. The fair value of the net assets acquired is preliminary pending the final valuation of those assets. As a result, goodwill is also preliminary since it has been recorded as the excess of the purchase price over the estimated fair value of the net assets acquired. The Company incurred $0.8 million and $0.9 million of expenses related to the acquisition for the three and nine months ended March 31, 2016 , which are included within selling, general and administrative expenses in the consolidated statements of income. The acquired business contributed revenues of $3.5 million and operating income of $0.7 million for the period from February 1, 2016 to March 31, 2016.

Other In the three and nine months ended March 31, 2015 our results of operations were materially impacted by charges resulting from a change in estimate related to an acquired EPC joint venture project in the Electrical Infrastructure segment. The charges resulted in a reduction to operating income of $28.5 million and $54.7 million and an after-tax reduction of $9.7 million and $18.7 million to net income attributable to Matrix Service Company, respectively. The Company recorded additional charges on this project during the three and nine months ended March 31, 2016, which resulted in a reduction to operating income of $1.6 million and $7.1 million and an after-tax reduction to net income attributable to Matrix Service Company of $0.5 million and $2.5 million , respectively. The fiscal 2016 project charges are attributable to higher than expected project closeout costs. The Company reached substantial completion on the project in the fourth quarter of fiscal 2015.

Debt Disclosure [Abstract]
Debt	Debt The Company has a five-year $200.0 million senior secured revolving credit facility under a credit agreement (the "Credit Agreement") that expires March 13, 2019 . Advances under the credit facility may be used for working capital, acquisitions, capital expenditures, issuances of letters of credit and other lawful purposes. The Credit Agreement includes the following covenants and borrowing limitations: • Our Senior Leverage Ratio, as defined in the agreement, may not exceed 2.50 to 1.00 , determined as of the end of each fiscal quarter. • We are required to maintain a Fixed Charge Coverage Ratio, as defined in the agreement, greater than or equal to 1.25 to 1.00 , determined as of the end of each fiscal quarter. • Asset dispositions (other than inventory and obsolete or unneeded equipment disposed of in the ordinary course of business) are limited to $20.0 million per 12-month period. Amounts borrowed under the Credit Agreement bear interest at LIBOR or an Alternate Base Rate, plus in each case, an additional margin based on the Senior Leverage Ratio. The additional margin on Alternate Base Rate and LIBOR-based loans ranges between 0.25% and 1.0% and between 1.25% and 2.0% , respectively. The Credit Agreement also permits us to borrow in Canadian dollars with a sub-limit of U.S. $40.0 million . Amounts borrowed in Canadian dollars will bear interest either at the CDOR Rate, plus an additional margin based on the Senior Leverage Ratio ranging from 1.25% to 2.0% , or at the Canadian Prime Rate, plus an additional margin based on the Senior Leverage Ratio ranging from 1.75% to 2.5% . The CDOR Rate is equal to the sum of the annual rate of interest, which is the rate determined as being the arithmetic average of the quotations of all institutions listed in respect of the relevant CDOR interest period for Canadian Dollar denominated bankers’ acceptances, plus 0.1% . The Canadian Prime Rate is equal to the greater of (i) the rate of interest per annum most recently announced or established by JPMorgan Chase Bank, N.A., Toronto Branch as its reference rate in effect on such day for determining interest rates for Canadian Dollar denominated commercial loans in Canada and (ii) the CDOR Rate plus 1.0%. The Unused Credit Facility Fee is between 0.20% and 0.35% based on the Senior Leverage Ratio. The Credit Agreement includes a Senior Leverage Ratio covenant, which provides that Consolidated Funded Indebtedness, as of the end of any fiscal quarter, may not exceed 2.5 times Consolidated EBITDA, as defined in the Credit Agreement, over the previous four quarters. For the four quarters ended March 31, 2016 , Consolidated EBITDA, as defined in the Credit Agreement, was $76.4 million . Accordingly, at March 31, 2016 , there was a restriction on our ability to access the full amount of the credit facility. Consolidated Funded Indebtedness at March 31, 2016 was $16.8 million . Availability under the senior credit facility was as follows: March 31, June 30, (In thousands) Senior credit facility $ 200,000 $ 200,000 Capacity constraint due to the Senior Leverage Ratio 9,013 54,968 Capacity under the credit facility 190,987 145,032 Borrowings outstanding 3,845 8,804 Letters of credit 20,612 40,587 Availability under the senior credit facility $ 166,530 $ 95,641 Outstanding borrowings at March 31, 2016 under our Credit Agreement were used for Canadian dollar advances required for short term working capital, including cross-border purchases of materials and services.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We use the asset and liability approach for financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances based on our judgments and estimates are established when necessary to reduce deferred tax assets to the amount expected to be realized in future operating results. Company management believes that realization of deferred tax assets in excess of the valuation allowance is more likely than not. Our estimates are based on facts and circumstances in existence as well as interpretations of existing tax regulations and laws applied to the facts and circumstances. The Company provides for income taxes regardless of whether it has received a tax assessment. Taxes are provided when it is considered probable that additional taxes will be due in excess of amounts included in the tax return. The Company regularly reviews exposure to additional income taxes due, and as further information is known or events occur, adjustments may be recorded. Our effective tax rate for the three months ended March 31, 2016 was 41.4% compared to 10.4% in the same period a year earlier. Our effective tax rate for the nine months ended March 31, 2016 was 35.6% compared to (33.2)% in the same period a year earlier. Our effective tax rates for the three and nine months ended March 31, 2016 and 2015 were impacted in part by the acquired EPC joint venture project charges in which the Company has a 65% interest and does not receive a tax benefit. The Company recorded discrete expenses of $0.1 million during the three months ended March 31, 2016 and recorded $1.3 million of discrete benefits during the nine months ended March 31, 2016 . The discrete benefits primarily relate to the retroactive application of the R&D tax credit and other tax credits. As stated in Note 1, the Company has elected to retrospectively early adopt ASU 2015-17, effective for the quarter ended December 31, 2015. The quantitative effects of the change on the prior balance sheet presented, for the fiscal year ended June 30, 2015, resulted in a reclassification of $6.6 million and $6.6 million from the "Deferred income taxes" current asset and liability financial statement line items, respectively, to the "Deferred income taxes" asset and liability financial statement line items included in the noncurrent asset and liability sections of the balance sheet.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance Reserves The Company maintains insurance coverage for various aspects of its operations. However, exposure to potential losses is retained through the use of deductibles, self-insured retentions and coverage limits. Typically our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials and workmanship. The Company may also be required to name the customer as an additional insured up to the limits of insurance available, or we may be required to purchase special insurance policies or surety bonds for specific customers or provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects. Matrix maintains a performance and payment bonding line sufficient to support the business. The Company generally requires its subcontractors to indemnify the Company and the Company’s customer and name the Company as an additional insured for activities arising out of the subcontractors’ work. We also require certain subcontractors to provide additional insurance policies, including surety bonds in favor of the Company, to secure the subcontractors’ work or as required by the subcontract. There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers. Unapproved Change Orders and Claims Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders and claims of $11.1 million at March 31, 2016 and $12.7 million at June 30, 2015 . Generally, collection of amounts related to unapproved change orders and claims is expected within twelve months. However, since customers may not pay these amounts until final resolution of related claims, collection of these amounts may extend beyond one year. Other The Company and its subsidiaries are participants in various legal actions. It is the opinion of management that none of the known legal actions will have a material impact on the Company’s financial position, results of operations or liquidity.
