The Remediation Establishment Census: Firms and Employment by State

Illustration: an unmarked work van and palletised drying equipment in a small company yard.

The finding

This remediation establishment census counts 9,387 private establishments and 96,727 employees across 52 US jurisdictions in NAICS 562910 for 2026Q1, per the BLS Quarterly Census of Employment and Wages. Read the scope carefully: NAICS 562910 is Remediation Services, meaning environmental remediation of contaminated soil, groundwater, asbestos and lead. It is not water damage or fire restoration of buildings, which BLS and the Census Bureau scatter across construction and other services codes. This is the closest available official count, and the reason no clean official count of restoration exists.

Key findings

  1. BLS QCEW records 9,387 private establishments and 96,727 employees in NAICS 562910 across 52 jurisdictions in 2026Q1.
  2. NAICS 562910 is environmental remediation, not building restoration. Per the US Census Bureau NAICS 562910 definition, the code covers remediation and cleanup of contaminated buildings, mine sites, soil and groundwater, including asbestos and lead abatement. Fire and flood restoration of buildings sits elsewhere, so no figure in this report is a count of restoration firms.
  3. The national fragmentation score computed from the QCEW 2026Q1 file is 10.3 employees per establishment, and the median state sits at 8.5. This is a sector of small firms.
  4. Washington is the most consolidated market at 21.1 employees per establishment in 2026Q1, against 4.8 in Rhode Island, a 4.4 times difference per BLS QCEW.
  5. Per BLS QCEW for 2026Q1, California holds the most establishments at 758, which is 8.1% of the national count.
  6. Alaska has the highest establishment density at 10.00 establishments per 100,000 residents, derived from QCEW 2026Q1 counts and US Census Bureau 2025 population estimates.
  7. Between 2022Q4 and 2026Q1, BLS QCEW shows establishments in NAICS 562910 rising by 1,102 nationally, or +13.3%. 45 of 52 jurisdictions gained establishments and 7 lost them.
  8. The largest absolute gain since 2022Q4 is California at +151 establishments, and the largest decline is New Jersey at -23, per BLS QCEW.

What NAICS 562910 counts, and what it leaves out

Every figure in this report comes from NAICS 562910. Per the US Census Bureau NAICS 562910 definition, that code is Remediation Services, and it comprises establishments primarily engaged in the remediation and cleanup of contaminated buildings, mine sites, soil and groundwater. Asbestos abatement, lead paint abatement, hazardous waste site cleanup and underground storage tank removal all sit here.

Water damage restoration and fire restoration of buildings do not. That work is distributed across several codes depending on what the establishment primarily does. Reconstruction after a loss falls under residential and nonresidential building construction, NAICS 236, and under specialty trade contractors, NAICS 238990. Cleanup and drying services fall under other services to buildings and dwellings, NAICS 561790, and carpet and upholstery cleaning, NAICS 561720.

The consequence is direct. Per BLS QCEW, the 9,387 establishments counted here in 2026Q1 are an environmental remediation sector, which overlaps the restoration trade at the contaminated end and misses it entirely at the water and fire end. Presenting this as the restoration industry would be wrong, which is why we are not doing it.

What the figures are good for is the abatement and environmental side of the market: how many firms operate, how large they are, where they cluster, and whether their number is rising or falling. Those questions have real answers in this file. For mould work specifically, our mold licensee density report counts licence holders on the Texas, Florida and New York registers.

Establishment density per 100,000 residents

Absolute counts follow population. Dividing by residents shows where remediation capacity is genuinely thick on the ground, which is the figure that matters if you are deciding whether a market is already served. The national rate computed from the QCEW 2026Q1 file and US Census Bureau 2025 population is 2.73 establishments per 100,000 residents.

The fragmentation score

The fragmentation score used here is simply employment divided by establishments: the average number of employees per firm location. A low score means a market of small independent operators. A high score means fewer, larger firms. The national figure from the QCEW 2026Q1 file is 10.3 employees per establishment, and the median state is 8.5.

The practical difference for someone entering a market is about who they will be bidding against. In Rhode Island, at 4.8 employees per establishment in 2026Q1, the competition is mostly owner-operators and very small crews, so a new entrant with two trucks is a normal competitor rather than an outsider. Our restoration job size distribution shows how much of the recorded disaster damage is small-dollar work.

In Washington, at 21.1 employees per establishment, the same work is held by firms with real overhead, standing contracts and the capacity to staff a large loss. A small entrant there is more likely to subcontract to those firms than to compete with them for the primary contract.

Multi-year change in establishment counts

The QCEW file carries earlier quarters, so the direction of travel is computable rather than asserted. Comparing 2022Q4 with 2026Q1, establishments in NAICS 562910 rose by 1,102 nationally, from 8,285 to 9,387, which is +13.3% per BLS QCEW.

On a percentage basis the ranking shifts, because small states move a long way on a few firms. Nevada grew +39.0% between 2022Q4 and 2026Q1 on a gain of +32 establishments, while District of Columbia fell -24.0% on a change of -6, per BLS QCEW. Treat percentage moves in small jurisdictions as noise unless the absolute change is also material.

Average weekly wage by state

QCEW reports an average weekly wage per establishment payroll, which is a different measurement from the occupational wage series. It covers everyone on the payroll, including office and management staff, so it is an establishment cost figure rather than a technician’s pay. The highest in 2026Q1 is Alaska at $2,441 per week per BLS QCEW.

Why published market-size figures disagree

Market-size estimates for restoration vary by a wide margin between publishers, and the scope problem described above is the main reason. A report that counts only NAICS 562910 produces a small number. One that adds NAICS 561790 and 561720 produces a larger one. One that includes post-loss reconstruction under NAICS 236 and 238990 produces a far larger one again, because reconstruction revenue dwarfs the mitigation phase.

None of those choices is wrong in itself. The problem is that the scope is rarely stated, so two figures that look comparable are counting different industries. The first question to ask of any restoration market figure is which NAICS codes it includes, and the second is whether it counts mitigation revenue only or reconstruction as well.

That is why this report publishes a count for one code and labels it precisely: 9,387 private establishments in NAICS 562910 in 2026Q1, per BLS QCEW, which is environmental remediation and not the restoration industry.

Method

How we counted. We retrieved the BLS Quarterly Census of Employment and Wages industry files for NAICS 562910 for five quarters, 2022Q4 through 2026Q1, on 2 October 2026. We kept rows at aggregation level 58, which is state by NAICS industry, and ownership code 5, private. Public-sector rows are excluded because they are a handful of state agencies that distort the per-firm figures. That leaves 52 jurisdictions in 2026Q1. Establishment counts are the quarterly establishment count, employment is the third-month employment level, and the wage is the reported average weekly wage. Establishments per 100,000 residents uses US Census Bureau Vintage 2025 state population estimates. The fragmentation score is employment divided by establishments. The multi-year change compares the 2026Q1 establishment count against 2022Q4 for the 52 jurisdictions present in both files. BLS suppresses employment and wage figures for DC, SD, VT, WY, which are excluded from the fragmentation and wage rankings.

What this does not show

What this does not show

  • This is not the restoration industry. NAICS 562910 is environmental remediation. Water damage and fire restoration of buildings sit in construction codes 236 and 238990 and in services codes 561790 and 561720, none of which are counted here. Any use of these figures as a restoration industry count is a misuse.
  • QCEW counts establishments, not firms. A company with branches in four states appears four times or more. The counts describe physical locations with payroll, so they overstate the number of distinct businesses.
  • Establishments are classified by primary activity. A firm that does both abatement and water damage work is coded once, to whichever activity dominates its revenue. Mixed firms are therefore invisible as mixed.
  • Only payrolled employment is covered. QCEW is built from unemployment insurance filings, so sole proprietors without employees and most independent contractors are absent. In a sector of small operators that is a significant gap.
  • Suppression removes data. BLS withholds employment and wage figures where publishing them would disclose an individual employer, which affects DC, SD, VT, WY in 2026Q1.
  • The latest quarter is preliminary. QCEW revises recent quarters, so the newest figures will change slightly in later releases.
  • Establishment growth is not revenue growth. More locations can mean a growing market or the same market split into smaller units.

Most quotable figures

  1. BLS QCEW counts 9,387 private establishments and 96,727 employees in NAICS 562910 Remediation Services across 52 US jurisdictions in 2026Q1.
  2. NAICS 562910 is environmental remediation, not building restoration: water damage and fire restoration are distributed across NAICS 236, 238990, 561790 and 561720, which is why published restoration market-size figures disagree so widely (US Census Bureau NAICS definitions).
  3. The sector averages 10.3 employees per establishment nationally, with a median state of 8.5, making it a market of small firms (computed from BLS QCEW, 2026Q1).
  4. Establishments in NAICS 562910 rose +13.3% between 2022Q4 and 2026Q1, with 45 of 52 jurisdictions gaining and 7 losing (computed from BLS QCEW).

Questions this report answers

How many remediation companies are there in the United States?

BLS QCEW records 9,387 private establishments in NAICS 562910 Remediation Services in 2026Q1. That counts locations rather than companies, and it covers environmental remediation rather than water damage restoration.

Does NAICS 562910 include water damage restoration?

No. NAICS 562910 covers remediation of contaminated buildings, mine sites, soil and groundwater, including asbestos and lead abatement. Water damage drying and cleanup is classified under NAICS 561790, carpet cleaning under 561720, and post-loss reconstruction under NAICS 236 and 238990.

Is there an official count of the restoration industry?

Not as a single number. No NAICS code isolates fire and water damage restoration, so any industry total is assembled from parts of several codes. The choice of which parts to include is the main reason published market-size figures vary so much.

Which state has the most remediation establishments?

California, with 758 private establishments in NAICS 562910 in 2026Q1 per BLS QCEW, which is 8.1% of the national count.

Is the remediation market fragmented or consolidated?

Fragmented. The national average computed from the BLS QCEW 2026Q1 file is 10.3 employees per establishment, and the median state is 8.5. Rhode Island is the most fragmented at 4.8 and Washington the most consolidated at 21.1.

Is the number of remediation firms growing?

Yes, modestly. Establishments rose +13.3% between 2022Q4 and 2026Q1 per BLS QCEW, from 8,285 to 9,387. 45 jurisdictions gained and 7 lost.
