Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Significant Accounting Policies Basis of Presentation 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 U.S. generally accepted accounting principles ("GAAP") for complete financial statements. The information furnished reflects all adjustments, consisting of normal recurring adjustments, 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, 2019 , included in the Company’s Annual Report on Form 10-K for the year then ended. The results of operations for the three-month period ended September 30, 2019 may not necessarily be indicative of the results of operations for the full year ending June 30, 2020 . Significant Accounting Policies The Company has updated its significant accounting policies to include its lease accounting policy as a result of adopting the Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) on July 1, 2019. The Company's other significant accounting policies are detailed in “Note 1 - Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended June 30, 2019. Leases Adoption of New Leases Standard In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . Under this guidance, lessees are required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated operating lease liability or finance lease liability. The right-of-use asset represents the lessee's right to use, or control the use of, a specified asset for the specified lease term. The lease liability represents the lessee's obligation to make lease payments arising from the lease, measured on a discounted basis. Based on certain characteristics, leases are classified as operating leases or finance leases. Operating lease liabilities and right-of-use assets are adjusted to result in a single straight-line lease expense over the life of the lease. Finance lease liabilities and right-of-use assets, which contain provisions similar to capital leases under the prior accounting standards, result in the recognition of interest expense on the lease liability and amortization expense on the right-of-use asset over the term of the lease. On July 1, 2019, the Company adopted the standard using the modified retrospective method. The modified retrospective method permits the Company to record right-of-use assets and lease liabilities for existing leases as of the date of adoption rather than at the beginning of the earliest period presented. The Company recorded operating lease right-of-use assets of $24.6 million and operating lease liabilities of $25.8 million as of July 1, 2019. The adoption of the standard did not have a material impact on the Company’s retained earnings, Condensed Consolidated Statements of Income or Condensed Consolidated Statements of Cash Flows. Financial results reported in prior periods are unchanged and reflect the prior lease accounting standards in place at the time. The Company elected the package of practical expedients permitted under the transition guidance for the new standard, which among other things, allowed the Company to carry forward the historical lease classification of its existing leases. All of the Company's existing leases were classified as operating leases prior to adoption and have retained this classification after adoption. In addition, the Company elected not to utilize the hindsight practical expedient to determine the lease term for existing leases at adoption. Lease Accounting Policy The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. The Company determines if an arrangement is or contains a lease at inception of the arrangement. An arrangement is determined to be a lease if it conveys the right to control the use of identified property or equipment for a period of time in exchange for consideration. If certain criteria are satisfied, the lease is classified as a financing lease. If none of these criteria are satisfied, the lease is considered an operating lease. All of the Company's leases are classified as operating leases. Operating lease right-of-use assets are recognized as the present value of future lease payments over the lease term as of the commencement date, plus any lease payments made prior to commencement, and less any lease incentives received. Operating right-of-use assets are presented as noncurrent in the Condensed Consolidated Balance Sheets. Operating lease liabilities are recognized as the present value of the future lease payments over the lease term as of the commencement date and are presented as current and noncurrent in the Condensed Consolidated Balance Sheets. The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases with an initial term of 12 months or less. The lease term used to measure the right-of-use assets and lease liabilities is generally the non-cancelable lease term for real estate leases and information technology equipment. Construction equipment is typically rented on a "month-to-month" basis and the lease term is estimated based on the expected duration of the rental. An option to renew or terminate a lease is included in the lease term when it is reasonably certain that the Company will exercise the option. Renewal options for real estate leases are typically for five years or less. Future lease payments are discounted based on the Company's estimate of its incremental borrowing rate at lease commencement. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments. Determinations with respect to lease term, including any renewals, incremental borrowing rate, and future lease payments require the use of judgment based on the facts and circumstances related to each lease. The Company considers various factors, including economic incentives, intent, past history and business need, to determine the likelihood that a renewal option will be exercised. After the commencement date, operating lease expense is recognized based on the undiscounted future lease payments over the remaining lease term on a straight-line basis. Lease expense related to short-term leases is recognized on a straight-line basis over the lease term. Lease expense is included in cost of revenue and in selling, general and administrative expenses in the Condensed Consolidated Statements of Income. See Note 3 - Leases for the required periodic disclosures about the Company's leases. Recently Issued Accounting Standards Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments On June 16, 2016, the FASB issued ASU 2016-13, which will change how the Company accounts for credit losses, including those related to its trade accounts receivable. The amendments in this update require a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The income statement will reflect any increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. Current GAAP delays the recognition of the full amount of credit losses until the loss is probable of occurring. The amendments in this update eliminate the probable initial recognition threshold and, instead, reflect the Company's current estimate of all expected credit losses. In addition, current guidance limits the information the Company may consider in measuring a credit loss to its past events and current conditions. The amendments in this update broaden the information the Company may consider in developing its expected credit loss estimate to include forecasted information. The Company will adopt these amendments on July 1, 2020. The Company must apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. At this time, the Company does not expect this update will have a material impact on its estimate of the allowance for uncollectible accounts.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Remaining Performance Obligations The Company had $756.7 million of remaining performance obligations yet to be satisfied as of September 30, 2019 . The Company expects to recognize approximately $637.6 million of its remaining performance obligations as revenue within the next twelve months. Contract Balances Contract terms with customers include the timing of billing and payment, which usually differs from the timing of revenue recognition. As a result, we carry contract assets and liabilities in our balance sheet. These contract assets and liabilities are calculated on a contract-by-contract basis and reported on a net basis at the end of each period and are classified as current. We present our contract assets in the balance sheet as Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts ("CIE"). CIE consists of revenue recognized in excess of billings. We present our contract liabilities in the balance sheet as Billings on Uncompleted Contracts in Excess of Costs and Estimated Earnings ("BIE"). BIE consists of advance payments and billings in excess of revenue recognized. The following table provides information about CIE and BIE: September 30, June 30, Change (in thousands) Costs and estimated earnings in excess of billings on uncompleted contracts $ 65,996 $ 96,083 $ (30,087 ) Billings on uncompleted contracts in excess of costs and estimated earnings (130,191 ) (105,626 ) (24,565 ) Net contract liabilities $ (64,195 ) $ (9,543 ) $ (54,652 ) The difference between the beginning and ending balances of the Company's CIE and BIE primarily results from the timing of revenue recognized relative to its billings. The amount of revenue recognized during the three months ended September 30, 2019 that was included in the prior period BIE balance was $72.0 million . This revenue consists primarily of work performed during the period on contracts with customers that had advance billings. Progress billings in accounts receivable at September 30, 2019 and June 30, 2019 included retentions to be collected within one year of $31.3 million and $21.9 million , respectively. Contract retentions collectible beyond one year are included in other assets in the Condensed Consolidated Balance Sheet and totaled $10.4 million as of September 30, 2019 and $17.7 million as of June 30, 2019 . Disaggregated Revenue Revenue disaggregated by reportable segment is presented in Note 9 - Segment Information. The following series of tables presents revenue disaggregated by geographic area where the work was performed and by contract type: Geographic Disaggregation: Three Months Ended September 30, September 30, (In thousands) United States $ 314,416 $ 310,137 Canada 21,170 7,081 Other international 2,511 1,293 Total Revenue $ 338,097 $ 318,511 Contract Type Disaggregation: Three Months Ended September 30, September 30, (In thousands) Fixed-price contracts $ 176,320 $ 179,122 Time and materials and other cost reimbursable contracts 161,777 139,389 Total Revenue $ 338,097 $ 318,511 Typically, the Company assumes more risk with fixed-price contracts since increases in cost to perform the work may not be recoverable. However, these types of contracts typically offer higher profits than time and materials and other cost reimbursable contracts when completed at or below the costs originally estimated. The profitability of time and materials and other cost reimbursable contracts is typically lower than fixed-price contracts and is usually less volatile than fixed-price contracts since the profit component is factored into the rates charged for labor, equipment and materials, or is expressed in the contract as a percentage of the reimbursable costs incurred.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	Leases The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. Real estate leases accounted for approximately 83% of all right-of-use assets as of September 30, 2019. Most real estate and information technology equipment leases generally have fixed payments that follow an agreed upon payment schedule and have remaining lease terms ranging from less than a year to 16 years. Construction equipment leases generally have "month-to-month" lease terms that automatically renew as long as the equipment remains in use. The components of lease expense in the Condensed Consolidated Statements of Income are as follows: Three Months Ended September 30, 2019 Lease expense Location of Expense in Statements of Income (in thousands) Operating lease expense Cost of revenues and selling, general and administrative expenses $ 3,117 Short-term lease expense (1) Cost of revenues 9,608 Total lease expense $ 12,725 (1) Represents the lease expense of equipment that is subject to month-to-month rental agreements with expected rental durations of less than one year.

Leases [Abstract]
Leases	Lease Accounting Policy The Company enters into lease arrangements for real estate, construction equipment and information technology equipment in the normal course of business. The Company determines if an arrangement is or contains a lease at inception of the arrangement. An arrangement is determined to be a lease if it conveys the right to control the use of identified property or equipment for a period of time in exchange for consideration. If certain criteria are satisfied, the lease is classified as a financing lease. If none of these criteria are satisfied, the lease is considered an operating lease. All of the Company's leases are classified as operating leases. Operating lease right-of-use assets are recognized as the present value of future lease payments over the lease term as of the commencement date, plus any lease payments made prior to commencement, and less any lease incentives received. Operating right-of-use assets are presented as noncurrent in the Condensed Consolidated Balance Sheets. Operating lease liabilities are recognized as the present value of the future lease payments over the lease term as of the commencement date and are presented as current and noncurrent in the Condensed Consolidated Balance Sheets. The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases with an initial term of 12 months or less. The lease term used to measure the right-of-use assets and lease liabilities is generally the non-cancelable lease term for real estate leases and information technology equipment. Construction equipment is typically rented on a "month-to-month" basis and the lease term is estimated based on the expected duration of the rental. An option to renew or terminate a lease is included in the lease term when it is reasonably certain that the Company will exercise the option. Renewal options for real estate leases are typically for five years or less. Future lease payments are discounted based on the Company's estimate of its incremental borrowing rate at lease commencement. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments. Determinations with respect to lease term, including any renewals, incremental borrowing rate, and future lease payments require the use of judgment based on the facts and circumstances related to each lease. The Company considers various factors, including economic incentives, intent, past history and business need, to determine the likelihood that a renewal option will be exercised. After the commencement date, operating lease expense is recognized based on the undiscounted future lease payments over the remaining lease term on a straight-line basis. Lease expense related to short-term leases is recognized on a straight-line basis over the lease term. Lease expense is included in cost of revenue and in selling, general and administrative expenses in the Condensed Consolidated Statements of Income.
