Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. References to the “Company,” “EMCOR,” “we,” “us,” “our” and similar words refer to EMCOR Group, Inc. and its consolidated subsidiaries unless the context indicates otherwise. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission. In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of a normal recurring nature) necessary to present fairly our financial position and the results of our operations. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 . During the third quarter of 2014, we ceased construction operations in the United Kingdom. As a result, the segment formerly named the United Kingdom construction and building services segment has been renamed the United Kingdom building services segment. Our reportable segments have been restated in all periods presented to reflect this change.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In April 2015, an accounting pronouncement was issued by the FASB to update the guidance related to the presentation of debt issuance costs. This guidance requires debt issuance costs, related to a recognized debt liability, be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than being presented as an asset. This pronouncement is effective retrospectively for fiscal years beginning after December 15, 2015, with early adoption permitted. We intend to adopt this pronouncement on January 1, 2016, and the adoption will not have a material impact on our financial position and/or results of operations. On January 1, 2015, we adopted the accounting pronouncement issued by the Financial Accounting Standards Board ("FASB") updating existing guidance on discontinued operations. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. This pronouncement is aimed at reducing the frequency of disposals reported as discontinued operations by focusing on strategic shifts that have or will have a major effect on an entity’s operations and financial results. We will consider this guidance in conjunction with future disposals, if any. In May 2014, an accounting pronouncement was issued by the FASB to clarify existing guidance on revenue recognition. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2017, with early adoption permitted. The guidance permits the use of one of two retrospective transition methods. We have not yet selected a transition method nor have we determined the effect that the adoption of the pronouncement may have on our financial position and/or results of operations.

Business Combinations [Abstract]
Acquisitions Of Businesses	Acquisitions of Businesses On June 1, 2015 , we acquired a company for an immaterial amount. This company primarily provides mechanical construction services and has been included in our United States mechanical construction and facilities services segment. The purchase price for this acquisition is subject to finalization based on certain contingencies provided for in the purchase agreement. The acquisition of this business was accounted for by the acquisition method, and the price paid for the acquired business has been allocated to its assets and liabilities, based upon the estimated fair value of its assets and liabilities at the date of the acquisition. During the three months ended June 30, 2015 and 2014 , respectively, we recorded a reversal of less than $0.1 million and $0.2 million of liabilities resulting in non-cash income attributable to contingent consideration arrangements relating to prior acquisitions. During the six months ended June 30, 2015 and 2014 , respectively, we recorded a net reversal of $0.2 million and $0.2 million of liabilities resulting in non-cash income attributable to contingent consideration arrangements relating to prior acquisitions.

Discontinued Operations and Disposal Groups [Abstract]
Disposition of Assets	Disposition of Assets In January 2014, we sold a subsidiary reported in our United States building services segment. Proceeds from the sale totaled approximately $1.1 million . Included in net income for the six months ended June 30, 2014 was a loss of $0.6 million from this sale, which is classified as a component of "Selling, general and administrative expenses" in the Condensed Consolidated Statements of Operations. Due to recurring losses over the last several years in the construction operations of our United Kingdom segment and our negative assessment of construction market conditions in the United Kingdom for the foreseeable future, we announced during the quarter ended June 30, 2013 our decision to withdraw from the construction market in the United Kingdom. During the third quarter of 2014, we ceased construction operations in the United Kingdom. The results of the construction operations of our United Kingdom segment for all periods are presented in our Condensed Consolidated Financial Statements as discontinued operations. The results of discontinued operations are as follows (in thousands): For the three months ended June 30, For the six months ended June 30, 2015 2014 2015 2014 Revenues $ 84 $ 5,137 $ 360 $ 13,983 Loss from discontinued operation, net of income taxes $ (114 ) $ (1,435 ) $ (469 ) $ (3,476 ) Diluted loss per share from discontinued operation $ (0.00 ) $ (0.02 ) $ (0.01 ) $ (0.05 ) Included in the Condensed Consolidated Balance Sheets at June 30, 2015 and December 31, 2014 are the following major classes of assets and liabilities associated with the discontinued operation (in thousands): June 30, December 31, Assets of discontinued operation: Current assets $ 4,318 $ 6,265 Non-current assets $ 114 $ 278 Liabilities of discontinued operation: Current liabilities $ 8,007 $ 10,743 Non-current liabilities $ 35 $ 94 At June 30, 2015, the assets and liabilities of the discontinued operation consisted of accounts receivable, contract retentions and contract warranty obligations that are expected to be collected or fulfilled in the ordinary course of business. Additionally at June 30, 2015, there remained $1.1 million of obligations related to employee severance and the termination of leased facilities, the majority of which is expected to be paid in 2015. The settlement of the remaining assets and liabilities may result in additional income and/or expenses. Such income and/or expenses are expected to be immaterial and will be reflected as an additional component of “Loss from discontinued operation” as incurred.

The 2011 Credit Agreement was effective November 21, 2011. Effective November 25, 2013, we amended and restated the 2011 Credit Agreement to provide for a $750.0 million revolving credit facility (the “2013 Revolving Credit Facility”) and a $350.0 million term loan (the "Term Loan") (collectively referred to as the "2013 Credit Agreement") expiring November 25, 2018 . The proceeds of the Term Loan were used to repay amounts drawn under the 2011 Credit Agreement. We may increase the 2013 Revolving Credit Facility to $1.05 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments. We may allocate up to $250.0 million of available borrowings under the 2013 Revolving Credit Facility to letters of credit for our account or for the account of any of our subsidiaries. Obligations under the 2013 Credit Agreement are guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets and most of the assets of most of our subsidiaries. The 2013 Revolving Credit Facility and the Term Loan contain various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of June 30, 2015 and December 31, 2014 . A commitment fee is payable on the average daily unused amount of the 2013 Revolving Credit Facility, which ranges from 0.20% to 0.30% , based on certain financial tests. The fee is 0.20% of the unused amount as of June 30, 2015 . Borrowings under the 2013 Credit Agreement bear interest at (1) a rate which is the prime commercial lending rate announced by Bank of Montreal from time to time ( 3.25% at June 30, 2015 ) plus 0.25% to 0.75% , based on certain financial tests or (2) United States dollar LIBOR ( 0.19% at June 30, 2015 ) plus 1.25% to 1.75% , based on certain financial tests. The interest rate in effect at June 30, 2015 was 1.44% . Fees for letters of credit issued under the 2013 Revolving Credit Facility range from 1.25% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. We capitalized approximately $3.0 million of debt issuance costs associated with the 2013 Credit Agreement. This amount is being amortized over the life of the agreement and is included as part of interest expense. We are required to make principal payments on the Term Loan in installments on the last day of March, June, September and December of each year, which commenced with the calendar quarter ended March 31, 2014, in the amount of $4.4 million , with a payment of all unpaid principal and interest due on November 25, 2018. As of June 30, 2015 and December 31, 2014 , the balance of the Term Loan was $323.8 million and $332.5 million , respectively. As of June 30, 2015 and December 31, 2014 , we had approximately $106.2 million and $95.5 million of letters of credit outstanding, respectively. There were no borrowings outstanding under the 2013 Revolving Credit Facility as of June 30, 2015 and December 31, 2014 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels: Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities. Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable. The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of June 30, 2015 and December 31, 2014 (in thousands): Assets at Fair Value as of June 30, 2015 Asset Category Level 1 Level 2 Level 3 Total Cash and cash equivalents (1) $ 360,849 — — $ 360,849 Restricted cash (2) 7,631 — — 7,631 Deferred compensation plan assets (3) 7,039 — — 7,039 Total $ 375,519 — — $ 375,519 Assets at Fair Value as of December 31, 2014 Asset Category Level 1 Level 2 Level 3 Total Cash and cash equivalents (1) $ 432,056 — — $ 432,056 Restricted cash (2) 6,474 — — 6,474 Deferred compensation plan assets (3) 3,139 — — 3,139 Total $ 441,669 — — $ 441,669 ________ (1) Cash and cash equivalents include money market funds with original maturity dates of three months or less, which are Level 1 assets. At June 30, 2015 and December 31, 2014 , we had $157.0 million and $156.7 million , respectively, in money market funds. (2) Restricted cash is classified as “Prepaid expenses and other” in the Condensed Consolidated Balance Sheets. (3) Deferred compensation plan assets are classified as "Other assets" in the Condensed Consolidated Balance Sheets. We believe that the carrying values of our financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities and low risk of counterparty default. The carrying value of our debt associated with the 2013 Credit Agreement approximates its fair value due to the variable rate on such debt.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended June 30, 2015 and 2014 , our income tax provision from continuing operations was $28.7 million and $25.2 million , respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.8% and 37.6% , respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended June 30, 2015 and 2014 , inclusive of discrete items, were 38.0% and 37.7% , respectively. For the six months ended June 30, 2015 and 2014 , our income tax provision from continuing operations was $49.0 million and $51.4 million , respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.8% and 37.6% , respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the six months ended June 30, 2015 and 2014 , inclusive of discrete items, were 37.9% and 37.7% , respectively. The decrease in the 2015 income tax provision was primarily due to decreased income before income taxes. The increase in the actual income tax rates on income from continuing operations was primarily due to a change in the mix of earnings among various jurisdictions. As of June 30, 2015 and December 31, 2014 , the amount of unrecognized income tax benefits for each period was $5.2 million (of which $3.0 million , if recognized, would favorably affect our effective income tax rate). We report interest expense related to unrecognized income tax benefits in the income tax provision. As of June 30, 2015 and December 31, 2014 , we had approximately $0.4 million and $0.3 million of accrued interest related to unrecognized income tax benefits included as a liability in the Condensed Consolidated Balance Sheets, respectively. For each of the three months ended June 30, 2015 and 2014 , less than $0.1 million of interest expense was recognized. For the six months ended June 30, 2015 and 2014 , less than $0.1 million of interest expense and less than $0.1 million of interest income was recognized, respectively. It is reasonably possible that approximately $3.3 million of unrecognized income tax benefits at June 30, 2015 , primarily relating to uncertain tax positions attributable to tax return filing positions, will significantly decrease in the next twelve months as a result of estimated settlements with taxing authorities and the expiration of applicable statutes of limitations. We file income tax returns with the Internal Revenue Service and various state, local and foreign tax agencies. The Company is currently under examination by various taxing authorities for the years 2008 through 2014. During the first quarter of 2014, the Internal Revenue Service finalized its audit of our federal income tax returns for the years 2010 through 2011. We agreed to and paid an assessment, for an immaterial amount, proposed by the Internal Revenue Service pursuant to such audit.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Government Contracts As a government contractor, we are subject to U.S. government audits and investigations relating to our operations, including claims for fines, penalties and compensatory and treble damages, and possible suspension or debarment from doing business with the government. Based on currently available information, we believe the outcome of ongoing government disputes and investigations will not have a material impact on our financial position, results of operations or liquidity. Legal Matters One of our subsidiaries was a subcontractor to a mechanical contractor (“Mechanical Contractor”) on a construction project where an explosion occurred. An investigation of the matter could not determine who was responsible for the explosion. As a result of the explosion, lawsuits have been commenced against various parties, but, to date, no lawsuits have been commenced against our subsidiary with respect to personal injury or damage to property as a consequence of the explosion. However, the Mechanical Contractor has asserted claims, in the context of an arbitration proceeding against our subsidiary, alleging that our subsidiary is responsible for a portion of the damages for which the Mechanical Contractor may be liable as a result of: (a) personal injury suffered by individuals as a result of the explosion and (b) the Mechanical Contractor’s legal fees and associated management costs in defending against any and all such claims. In the most recent filing with the Arbitrator, the Mechanical Contractor has stated claims against our subsidiary for alleged violations of the Connecticut and Massachusetts Unfair and Deceptive Trade Practices Acts in the ongoing arbitration proceeding. Further, the general contractor (as assignee of the Mechanical Contractor) on the construction project, and for whom the Mechanical Contractor worked, has alleged that our subsidiary is responsible for losses asserted by the owner of the project and/or the general contractor because of delays in completion of the project and for damages to the owner’s property. We believe, and have been advised by counsel, that we have a number of meritorious defenses to all such matters. We believe that the ultimate outcome of such matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity. Notwithstanding our assessment of the final impact of this matter, we are not able to estimate with any certainty the amount of loss, if any, which would be associated with an adverse resolution. One of our subsidiaries, USM, Inc. (“USM”), doing business in California provides, among other things, janitorial services to its customers by having those services performed by independent janitorial companies. USM and one of its customers, which owns retail stores (the “Customer”), are co-defendants in a federal class action lawsuit brought by five employees of USM’s California janitorial subcontractors. The action was commenced on September 5, 2013 in a Superior Court of California and was removed by USM on November 22, 2013 to the United States District Court for the Northern District of California. The employees allege in their complaint, among other things, that USM and the Customer, during a period that began before our acquisition of USM, violated a California statute that prohibits USM from entering into a contract with a janitorial subcontractor when it knows or should know that the contract does not include funds sufficient to allow the janitorial contractor to comply with all local, state and federal laws or regulations governing the labor or services to be provided. The employees have asserted that the amounts USM pays to its janitorial subcontractors are insufficient to allow those janitorial subcontractors to meet their obligations regarding, among other things, wages due for all hours their employees worked, minimum wages, overtime pay and meal and rest breaks. These employees seek to represent not only themselves, but also all other individuals who provided janitorial services at the Customer’s stores in California during the relevant four year time period. We do not believe USM or the Customer has violated the California statute or that the employees may bring the action as a class action on behalf of other employees of janitorial companies with whom USM subcontracted for the provision of janitorial services to the Customer. However, if the pending lawsuit is certified as a class action and USM is found to have violated the California statute, USM might have to pay significant damages and might be subject to similar lawsuits regarding the provision of janitorial services to its other customers in California. The plaintiffs seek a declaratory judgment that USM has violated the California statute, monetary damages, including all unpaid wages and thereon, restitution for unpaid wages, and an award of attorneys’ fees and costs. On February 17, 2015 , USM and its Customer entered into a consent decree which, subject to final approval of the consent decree by the federal judge in the United States District Court for the Northern District of California following a determination by the Court of the consent decree’s fairness, adequacy and reasonableness, will resolve the claims and defenses asserted in the class action. Under the terms of the consent decree, USM is to (a) pay an aggregate of $1.0 million (i) for monetary relief to the members of the class, (ii) for awards to the class representative plaintiffs, (iii) for California Labor Code Private Attorney General Act payments to the State of California for an immaterial amount, and (iv) for all costs of notice and administration of the claims process, (b) pay to counsel for the class an aggregate of $1.3 million , of which $0.25 million is to be allocated for their reimbursable costs and litigation expenses and $1.05 million is to be allocated for attorneys’ fees, and (c) establish procedures to monitor USM’s California subcontractors providing janitorial services to its Customer designed principally to ensure janitorial employees of those subcontractors are paid no less than minimum wage. The settlement amount was accrued for as of December 31, 2014. As of June 30, 2015, a payment of $1.0 million was made to a third party claims administrator who is holding the funds pending approval by the Court of the consent decree, and the remainder is expected to be paid before the end of 2015. We are involved in several other proceedings in which damages and claims have been asserted against us. Other potential claims may exist that have not yet been asserted against us. We believe that we have a number of valid defenses to such proceedings and claims and intend to vigorously defend ourselves. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity. Litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance. It is possible that some litigation matters for which reserves have not been established could be decided unfavorably to us, and that any such unfavorable decisions could have a material adverse effect on our financial position, results of operations or liquidity. Restructuring expenses Restructuring expenses were $0.4 million for the three and six months ended June 30, 2015. Restructuring expenses for the three and six months ended June 30, 2015 included $0.5 million of employee severance obligations and the reversal of $0.1 million relating to the termination of leased facilities.

As of June 30, 2015 , the balance of these restructuring obligations yet to be paid was $0.5 million , the majority of which is expected to be paid during 2015. No material expenses in connection with restructuring from continuing operations are expected to be incurred during the remainder of 2015.
