What commercial water damage restoration involves

Commercial water damage restoration returns a wet building to a dry, clean and usable condition after a pipe failure, roof leak, sprinkler discharge, sewer backup or flood. The work follows a set order:

Make the area safe. Power is shut off at the main breaker if water has reached circuits or equipment, and no one enters flooded areas or touches electrical equipment while the floor is wet.
Stop the source. The leak, failed fitting or roof defect is isolated. Under the ANSI/IICRC S500 standard, finding and correcting the source of the water is the property owner’s responsibility, though the owner can contract a restorer or specialist for it.
Identify the water. Clean water from a supply line is handled differently from sewage or water that carries chemical or biological contamination.
Extract and remove. Standing water is removed with extraction equipment. Materials that cannot be saved, such as wet ceiling tiles and insulation, are removed and bagged.
Dry. Dehumidifiers, air movers and, where suitable, heaters dry the structure. Moisture meters measure the moisture content of building materials and track drying until the materials reach a dry standard.
Clean. Hard surfaces are cleaned, and the subfloor under carpet or other flooring is cleaned and dried.
Rebuild. Drywall, ceilings, flooring and finishes are replaced once the structure is confirmed dry.

Large events that involve fire, storm or regional flooding are handled under disaster recovery services.

Standards and guidance

ANSI/IICRC S500. The current edition is the Fifth Edition (2021), and a consensus body has begun work on a revision. S500 covers water damage restoration in residential, commercial and institutional buildings and their systems and contents, including drying technology, safety and health, structural restoration, HVAC restoration and contents restoration.
EPA, drying within 24 to 48 hours. The EPA guide Mold Remediation in Schools and Commercial Buildings sets out responses to water damage within 24 to 48 hours. It lists material by material actions: ceiling tiles, cellulose insulation and fiberglass insulation are discarded and replaced; wallboard may be dried in place only if there is no obvious swelling and the seams are intact; carpet is extracted and dried with dehumidifiers and fans. Materials wet for more than 48 hours move to the guide’s mold remediation guidelines.
Contaminated water. EPA states that its drying guidance applies to clean water. For sewage or other contamination, personal protective equipment and containment are required by OSHA, and fans are not used until the water is confirmed clean.
Mold containment. Where mold is present, EPA generally recommends limited containment for areas of 10 to 100 square feet and full containment above 100 square feet, with the containment held under negative pressure. HVAC systems known or suspected to be contaminated with mold are not run.
Worker safety. OSHA warns that generators, pumps and pressure washers produce carbon monoxide and must be operated outdoors, never inside enclosed spaces. For mold cleanup, OSHA recommends hand, eye and respiratory protection, including an N-95 respirator.

Requirements vary by jurisdiction. The local building official decides permits for rebuild work, and the insurer’s policy terms govern the claim.

Preventive maintenance schedule for water damage prevention

Many commercial water losses start with something a routine check would find: a blocked roof drain, a clogged HVAC drip pan or a failing supply line. Planned checks reduce emergency calls and closures, and the dated records help show the insurer that the building was maintained.

Task	Recommended frequency	Basis
Inspect the roof, clear drains, scuppers and gutters	At least twice a year, preferably spring and fall, and after severe weather	NRCA
Keep HVAC drip pans clean, flowing and unobstructed	At each HVAC maintenance visit	EPA
Keep indoor relative humidity below 60 percent, ideally 30 to 50 percent	Continuous, checked at each visit	EPA
Repair plumbing and building envelope leaks	As soon as found	EPA
Check visible supply lines, water heaters and fixture connections for leaks or corrosion	Quarterly	Facility First program default, adjusted per site
Locate, label and exercise the main water shutoff valve	Annually	Facility First program default, adjusted per site
Check ceiling tiles and walls below roofs and plumbing for staining	Quarterly	Facility First program default, adjusted per site
Confirm emergency contacts, shutoff locations and the assigned restoration provider for each location	Annually and before storm season	Facility First program default, adjusted per site

The authority having jurisdiction, equipment manufacturers and the property’s insurer can require more frequent service, and each location’s schedule is set in its program and recorded on every visit.

Signs of hidden water damage

Stained or sagging ceiling tiles
Bubbling paint or swollen wallboard, or wallboard seams that have opened
Musty odors in back rooms, stockrooms or ceiling plenums
Cupped or lifting flooring, or carpet that stays damp
Condensation or standing water around HVAC units and drip pans
Water marks on walls below roof lines or near downspouts

EPA notes that vinyl wallpaper over drywall and wood paneling can act as vapor barriers and trap moisture behind them, so a clean surface does not always mean a dry wall.

Records to keep

Time the loss was discovered and the time mitigation began
Source of the water and the repair that stopped it
Water type (clean or contaminated) as assessed by the provider
Photos before, during and after the work
Moisture readings by location and date, from first visit to final dry readings
List of materials removed and discarded, and contents affected
Equipment placed and the dates it ran
Rebuild scope, permits where required and final photos
Insurer notifications, adjuster visits and claim numbers

The same records are collected at every location, so each claim file is complete when the adjuster asks for it. The policy terms and the adjuster decide what the claim requires.

How Facility First runs commercial water damage restoration across a portfolio

Request. The location reports the loss through the platform or by phone, with photos where it is safe to take them.
Triage. Facility First confirms the source, whether it has been stopped, whether power is affected and whether the water may be contaminated, then flags the request as urgent.
Dispatch. A vetted local restoration provider that holds the required licenses and insurance receives the work order. Where a related repair is needed, such as a roof or plumbing fix, that trade is dispatched in parallel.
Mitigation and drying. The provider extracts water, removes unsalvageable materials and records moisture readings on each visit until the materials are dry.
Close-out and verification. Final readings and photos are checked against the scope before rebuild begins.
Invoice. Work is invoiced in one format, with the documentation package ready for the claim.

Approval limits set by the client decide what proceeds immediately and what is quoted first. Where a water loss leaves a storefront or entrance unsecured, McCray can post an officer until the work is complete. See Security by McCray.

Water damage restoration for retail stores, restaurants and offices

Retail stores. Inventory, fixtures and display materials are moved away from the wet area first. Work is planned around trading hours, and sections of the sales floor may be closed while equipment runs.

Restaurants. OSHA advises discarding any food that has contacted floodwater. Reopening a food establishment after a flood or sewage backup is subject to local health department rules, which vary by jurisdiction.

Offices. EPA guidance for wet books and papers is to discard non-valuable items and, for valuable ones, to photocopy them or have them frozen or freeze-dried. Server rooms and IT closets are checked early because they often sit below plumbing or roof drains.

Frequently asked questions

How quickly does commercial water damage need to be dried?

EPA and CDC guidance calls for wet materials to be dried within 24 to 48 hours. Materials wet longer than 48 hours are handled under mold remediation guidelines.

Can wet drywall be saved?

According to EPA, wallboard may be dried in place if there is no obvious swelling and the seams are intact. Otherwise it is removed, discarded and replaced.

Who is responsible for fixing the source of the water?

Under ANSI/IICRC S500, finding and correcting the source of water intrusion is the property owner’s responsibility. Facility First can dispatch the plumbing or roofing repair alongside the restoration provider.

How often should a building be checked to prevent water damage?

Roofs and drains are inspected at least twice a year and after severe weather, HVAC drip pans are checked at each HVAC visit, and plumbing checks follow the schedule set for each location.

What documentation does an insurer need after a water loss?

Requirements depend on the policy and the adjuster. Facility First collects photos, moisture readings, the cause of loss, the list of materials removed and the drying timeline on every job.
