By rebuilding them from source records rather than accepting your reports. Expect a quality-of-earnings pass that ties revenue to invoices and cost to job records, a working-capital analysis on aged receivables and retainage, a revenue-by-customer schedule for three years, and for any recurring-revenue claim, a contract-by-contract schedule with term, renewal history, and margin per contract. The trade-specific version of each test is in the cards below.
Each card carries the three scale brackets with the EBITDA scope the source attached to them, who is actually buying, the operating attribute that explains the spread, and how a buyer verifies that attribute from source records. Every row is badged with its provenance.

What moves the multiple
Service-agreement density is the whole ballgame. The gap between the tuck-in band and the platform band is roughly 8 to 11 turns of EBITDA, and the single attribute that separates them is the share of revenue under a recurring maintenance agreement that is genuinely profitable.
How a buyer tests it in diligence
- •Recurring revenue proof: agreement count, renewal rate, and gross margin per agreement after fully burdened technician hours, not the quoted margin.
- •Maintenance pull-through: the repair and replacement revenue an agreement customer generates versus a non-agreement customer, traced customer by customer.
- •Install versus service margin split, computed from actual job cost rather than from a revenue category label.
Who is buying
The most consolidated of the trades. PitchBook counted a record 55 private-equity HVAC platform deals in 2024, a 72% increase year over year, and more than 60 deals in the first half of 2025. Sponsors buy local and regional operators as add-ons, build route density, then recapitalize the platform at a higher multiple.
Named platforms and deals: Apex Service Partners (Alpine Investors, with an Apollo Global Management investment in May 2026 at roughly $10B enterprise value, after about 60 add-ons in 2025 alone); Champions Group (Blackstone, February 2026, roughly $2.5B enterprise value at about 18.5x EBITDA); Sila Services (Goldman Sachs Alternatives majority recapitalization, November 2024, roughly $1.7B); Service Logic (Bain Capital and Mubadala, December 2025, over $1B).

What moves the multiple
Membership and service-plan revenue, plus the share of work that is non-discretionary emergency demand. A plumbing book that is mostly new-construction rough-in prices closer to the tuck-in band no matter how large it is, because the revenue does not repeat.
How a buyer tests it in diligence
- •Membership plan economics: active member count, monthly value, churn, and the margin on the visits the plan entitles a customer to.
- •Emergency versus scheduled versus new-construction revenue mix, taken from job records rather than from a self-reported estimate.
- •Whether dispatch and drive time are costed to the job. Residential service books routinely overstate margin by leaving them in overhead.
Who is buying
More than half of the largest US plumbing companies are private-equity backed, while over 75% of operators overall remain independent. Sponsors have put over $25B into residential home-services platforms across the past eight years, usually rolling plumbing together with HVAC and electrical into one multi-service residential brand.
Named platforms and deals: Apex Service Partners (Alpine Investors, $3.4B continuation vehicle); Champions Group (Blackstone, February 2026, roughly $2.5B at about 18.5x); Sila Services (Goldman Sachs Alternatives, November 2024, roughly $1.7B); Wrench Group (Leonard Green, TSG Consumer, Oak Hill); Redwood Services (Altas Partners).

Verify. Stated as EV/EBITDA unless the source says otherwise.
What moves the multiple
End-market mix, more than size. The same $4M of EBITDA prices near 6x as a general commercial electrician and near 10x as a qualified data-center or mission-critical power contractor, because the buyer is underwriting a different demand curve.
How a buyer tests it in diligence
- •Backlog quality: signed versus verbal, margin per project in backlog, and how much of it depends on one general contractor.
- •Work-in-progress accuracy. Over-billing and under-billing schedules are where a buyer finds that reported profit was borrowed from a future period.
- •Certification and qualified-personnel depth for premium end markets, because the premium multiple attaches to the capability, not to the revenue.
Who is buying
Financial sponsors account for roughly 75% of all electrical contractor M&A according to PitchBook, and lower-middle-market deal volume rose 13% in 2024 before expanding again through 2025 and 2026. The demand driver is specific: data-center buildout, grid modernization, and commercial electrification, against a hard technician shortage.
Named platforms and deals: Apex Service Partners (Alpine Investors, Apollo investment at roughly $10B enterprise value, May 2026); Truelink Capital and Prime Electric (January 2026 platform deal); MYR Group (NASDAQ: MYRG) acquiring Valley Electric and Comet Electric for $328M (October 2025); Platte River Equity and Team UIS (January 2026); Huron Capital and RK Electric; Broad Sky Partners and Commonwealth Electrical Technologies.

What moves the multiple
Whether the earnings repeat. Commercial roofing with recurring maintenance and inspection contracts reaches the top band; storm-chasing residential volume does not, because a buyer normalizes a storm year down to trend before applying any multiple.
How a buyer tests it in diligence
- •Storm-year normalization: revenue and margin by year with catastrophe-driven work isolated, so the buyer can see the underlying trend line.
- •Warranty and callback reserve. Roofing carries long warranty tails, and an under-reserved book is a direct purchase-price adjustment.
- •Recurring maintenance and inspection contract schedule, with the renewal history and the margin on each contract.
Who is buying
Private-equity-backed roofing platforms went from 17 at the start of 2023 to 56 by the end of 2024, and sponsors completed 134 roofing acquisitions in 2024, roughly one every 48 hours. The top five contractors control under 10% of the market and repair and replacement is about 64% of volume.
Named platforms and deals: Tecta America (Altas Partners), the largest private-equity-backed commercial platform at over $960M in revenue, with acquisitions including Alpine Roofing and Texas Roofing; Roofing Corp of America (HGGC); Latite Roofing (Sun Capital Partners, 2025); Leaf Home and Erie Home combination (Ares Management, Apollo Global Management, Gridiron Capital); on the distribution tier, QXO acquiring Beacon Roofing Supply for $11B and Home Depot acquiring SRS Distribution for $18.25B.

What moves the multiple
Contract term and account retention. This is the lowest-multiple trade on the page and the reason is structural: labor is 50% to 90% of job cost, so there is little operating cushion, and month-to-month accounts can leave the week after close.
How a buyer tests it in diligence
- •Contract schedule with remaining term, notice period, and pricing escalator per account. Month-to-month revenue is discounted hard.
- •Account turnover history. The BSCAI 2024 survey found 73% of firms lose under 10% of accounts a year, so a higher loss rate reads as a red flag rather than as normal.
- •Labor as a share of job cost per account, and whether supervisor and travel time are costed to the account or buried in overhead.
Who is buying
A market above $100B split across tens of thousands of local and regional operators. Sponsors build route density and centralize back-office work, which is where the margin expansion in their model comes from.

What moves the multiple
Contract maintenance share versus one-time design and install. The spread from 3x to 12x tracks almost entirely to how much of the book renews without being re-sold each spring.
How a buyer tests it in diligence
- •Maintenance contract base: annual contract value, renewal rate, and whether escalators keep pace with wage growth.
- •Seasonality and the winter revenue plan. A book that earns most of its revenue in three months needs a credible off-season cash story.
- •Crew-level gross profit per hour, because in a labor-constrained trade the buyer is underwriting productive capacity, not just revenue.
Who is buying
Between roughly 640,000 and 700,000 mostly local operators, with the top 50 companies holding only about 20% of the market. Sponsors are drawn to high cash conversion and to contract maintenance, lawn-care subscriptions, irrigation, and snow removal, all of which recur.

What moves the multiple
Whether crews are employees and whether estimating is systematized. A painting book that runs on subcontracted crews and hand-priced bids has almost nothing a buyer can scale, which caps it at the tuck-in band.
How a buyer tests it in diligence
- •Worker classification. Subcontracted crews create reclassification exposure that a buyer will either indemnify against or price into the multiple.
- •Estimating accuracy: bid hours versus actual hours by job type, which is the fastest read on whether reported margin is real.
- •Commercial and HOA agreement schedule, with term, renewal history, and margin per agreement.
Who is buying
Between roughly 75% and 88% of painting contractors are small independent shops. Sponsors, search funds, and home-services holding companies target the ones with commercial or HOA recurring agreements, a W-2 workforce rather than subcontracted crews, and digital estimating already in place.

What moves the multiple
The lowest tuck-in band on this page, roughly 3x, and the reason is that the work is bid, one-time, and weather-exposed. The trades that break out of it are the repair and restoration niches, where the same crew skill produces repeat and warranty-backed revenue.
How a buyer tests it in diligence
- •Bid-to-actual cost variance by job. In a 3x trade there is no room for a costing error, so a buyer verifies the margin job by job.
- •Retainage and lien position across open contracts, because a large share of the balance sheet is money already earned and not yet released.
- •Equipment condition and replacement schedule. Deferred capital expenditure is an adjustment to EBITDA, not a saving.

What moves the multiple
Fabrication capability and contract-glazing backlog quality. This is a project trade with long lead times, so the buyer underwrites the schedule and the work-in-progress accuracy before anything else.
How a buyer tests it in diligence
- •Work-in-progress and percentage-of-completion accuracy on open glazing contracts. This is the number most often wrong in this trade and it moves reported profit directly.
- •Retainage aging and the closeout process on completed contracts.
- •Material price exposure and whether contracts carry escalation clauses on aluminum and glass.
Who is buying
Consolidation runs on both sides of the trade, glass fabrication and contract glazing installation. Buyers are after geographic reach, purchasing power on raw material, and automation in fabrication.

Use the all-contractor net-profit anchor below and the cross-trade operating metrics, and note that contract glazing collects on commercial-project terms, so it runs closer to the mechanical and general-contractor cycles than to a residential service book.

What moves the multiple
Service and repair mix versus new-construction install, plus commercial dock and door service agreements. The trade's multiple range is unusually wide, roughly 3.5x to 16x, because the same product sold as an install is a one-time sale and sold as a service contract is an annuity.
How a buyer tests it in diligence
- •Service revenue as a share of total, with repeat-customer history rather than a revenue-category label.
- •Commercial dock and door maintenance agreements: count, term, and margin after travel time is costed.
- •Parts inventory accuracy and margin. Inventory shrink and mispriced parts quietly distort reported gross margin in this trade.
Who is buying
Over 15,000 independent operators, roughly 90% of them under $10M in revenue. More than ten private-equity platforms have formed since 2022, running 25 to 30 or more add-ons a year. Buyers are running the HVAC playbook on a trade with the same repair-and-replace demand profile.
Named platforms and deals: Guild Garage Group (Oak Hill Capital, March 2026, over $800M at about 16x EBITDA on $300M+ revenue after 25+ add-ons); GarageCo Holdings (Gridiron Capital, 2024, acquiring P.D.Q. Door, Apple Door Systems, and Cunningham Window & Door); US Dock & Door (Soundcore Capital Partners); DuraServ (Leonard Green & Partners, at a high-teens multiple); A1 Garage Door Service (Cortec Group); Door Pros America (Rotunda Capital Partners); Precision Door Service (Neighborly, KKR).
Operating benchmarks for doors and access systems
Level does not publish a doors and access DSO or gross-margin band. Residential service work in this trade collects on residential service terms, faster than any project trade, while the commercial dock and door side collects on commercial terms.

Verify. Stated as EV/EBITDA unless the source says otherwise.
What moves the multiple
Recurring monitoring revenue, priced as a separate asset. This is the one trade on the page where a buyer will value part of the business on a revenue multiple rather than an earnings multiple, because monitoring contracts behave like a subscription book.
How a buyer tests it in diligence
- •Monthly recurring revenue schedule: contract by contract, with attrition rate, remaining term, and gross margin per account.
- •Project versus recurring revenue split, and whether shared technicians and overhead are allocated between them honestly. Mixing the two is how a project shop gets mistaken for a recurring one.
- •Inspection and testing backlog against code-mandated frequency, which is the proof that the recurring revenue is contractual rather than habitual.
Who is buying
Capstone Partners counted 242 sector transactions in 2025, up 24.1% year over year, with private-equity add-ons at 45.9% of all deals and new platform investments up 33.3%. No contractor holds more than 5% share at the installation level, and code-mandated inspection and testing produces revenue that does not depend on a customer's discretionary budget.
Named platforms and deals: Pye-Barker Fire & Safety (Altas Partners and Leonard Green & Partners, with ADIA and GIC as minority investors, 41 companies acquired in 2025 alone); Pavion (Wind Point Partners, 70+ US locations); Everon, formerly ADT Commercial (GTCR); Sciens Building Solutions (Carlyle); Summit Companies (BDT & MSD Partners); Marmic Fire & Safety (KKR from HGGC, roughly $1B); APi Group (NYSE: APG) acquiring Chubb Fire & Security for $3.1B.

What moves the multiple
The share of revenue that is code-mandated recurring inspection and monitoring. The band from 4x to 20x is essentially a straight line in that one variable, which is why the tier note for the middle band names 40% recurring as the threshold.
How a buyer tests it in diligence
- •Inspection contract schedule tied to code frequency, with device counts per site and renewal history.
- •Deficiency-to-repair conversion rate. An inspection book that finds deficiencies and does not convert them into repair work is leaving the margin a buyer is paying for.
- •Technician licensing and certification coverage by jurisdiction, because the recurring revenue is only transferable if the credentials are.
Who is buying
Roughly 125 transactions in 2025, up about 67% year over year, with the top operators holding only about 20% of the market. The demand is code-mandated: inspection, testing, and monitoring happen on a legal schedule rather than on a budget cycle.
Named platforms and deals: Pye-Barker Fire & Safety (Altas Partners and Leonard Green & Partners, 57 acquisitions in 2025 and over 220 since 2019); Summit Companies (BDT & MSD Partners, 2025, from BlackRock Long Term Private Capital); APi Group (NYSE: APG) acquiring Chubb Fire & Security for $3.1B in 2022; Encore Fire Protection (Permira, 2025, roughly $1.8B); AI Fire (Blackstone, 2025, roughly $1.1B); Marmic Fire & Safety (KKR, roughly $1B); CertaSite (The Riverside Company).

What moves the multiple
Carrier and third-party-administrator program depth, balanced against how concentrated those relationships are. Program revenue is what gets a restoration company past the tuck-in band, and it is also the concentration risk that caps the multiple if one carrier is most of the book.
How a buyer tests it in diligence
- •Revenue by carrier and by third-party administrator, because program concentration in this trade routinely exceeds the 31.0% cross-trade median for a largest customer.
- •Aged receivables by claim status. Restoration receivables sit behind adjuster approval, so the aging tells the buyer how much of reported revenue is genuinely collectible.
- •Catastrophe-year normalization: a storm or wildfire year restated to trend, with the incremental subcontract and travel cost that came with it.
Who is buying
Roughly 15,000 independent operators, with the top five national brands under 20% of share combined. Sponsors have funded more than 50 distinct restoration platforms since 2018, drawn by non-discretionary demand, rising severe-weather frequency, and carrier and third-party-administrator relationships that are difficult to replicate.

Operating benchmarks for restoration and remediation
Level does not publish a restoration DSO or gross-margin band. Restoration collections run behind insurance adjustment rather than on standard trade terms, so neither a residential service band nor a commercial project band describes them well.
