What happens during a commercial walkthrough, and what goes into the quote?
A technician walks the space with the owner or manager, finds the source, outlines the wet area and records floor area, materials, access, power and operating hours. The quote that follows lists equipment, days, contents work and any after-hours time. You approve the first stage before work starts, and the rebuild is quoted later.
The walkthrough answers what a phone call cannot. How much floor is actually wet, and what material is on it? Is the water clean, and how long has it been standing? Where are the doors, the freight elevator and the dock, and who holds the key to the mechanical room? How many free circuits are there for dehumidifiers, and which parts of the building have to stay open?
A quote built from those answers has line items you can read. Air movers and LGR dehumidifiers are priced per unit per day, extraction by the square foot, contaminated water by the square foot at the Category 3 rate of $7–$15, and contents pack-out as its own line. Work outside business hours adds the emergency fee, and all of it is explained before any machine goes down.
Ask for the scope in writing and file it with the moisture log. Where several parties have a stake, such as an owner, a manager and a tenant, a single building record avoids three versions of what happened and when.
Can a business keep operating while its space dries?
Often in part. Barriers isolate the wet zone, loud work can wait until after hours, and cords and hoses are routed away from walkways. What stays open depends on the type of water, the size of the damp area and what the landlord, the insurer and the city allow. A contaminated restroom stays closed until it is cleaned and treated.
Electrical capacity is the limit people forget. Dehumidifiers and air movers draw real current, and a suite whose circuits already carry servers, kitchen gear or a full floor of lighting may have no room for them. The technician checks the available circuits during the walkthrough, because the drying plan has to run on the power the building can supply.
Noise and traffic are the other limits. Equipment runs around the clock until each zone meets its dry reference, so the scheduling question is where the loud units sit and who must walk past them. Customer entrances, exit paths and forklift lanes stay clear, and units are pulled from a zone as soon as its readings are done instead of waiting for the whole building.
Some spaces cannot stay open while wet. Clean water across a sales floor can usually be handled in sections. Sewage in a restroom closes that area, because the water is Category 3, the porous materials it touched are removed instead of saved, and nothing is dried until the surfaces have been cleaned.
A sprinkler head or a roof drain failed. Who does what?
Different trades own each failure. A fire-protection contractor repairs sprinkler pipe or a head and returns the system to service, a roofer or the building's maintenance team clears or repairs a roof drain, and a Texas-licensed plumber handles domestic lines. The restoration crew extracts, dries and documents what those failures released.
A sprinkler system is its own discipline. After a head has discharged or a pipe has split, isolating and recommissioning it is a decision for the fire department and the building's fire-protection contractor, and nobody on a drying crew should be closing or reopening those valves for you. Call them first and tell them what happened.
Roof drains and flat-roof ponding sit with the building envelope. If a drain blocked and the water found a seam, the wet ceiling below is the crew's work and the cause above is a roofer's. A stain under a rooftop air-conditioning unit is a question for an air-conditioning contractor before anyone repairs the ceiling.
Restroom fixtures, supply lines and water heaters are plumbing work under Texas Occupations Code Chapter 1301, and the state plumbing board's website lets you check a plumber's license. Valves can be closed, and extraction and drying can start, while those repairs are on the calendar, which matters most after a freeze or a storm when every trade is booked.
Who is responsible when one tenant's leak damages the suite below?
The lease, the building's rules and each party's insurance decide, not the crew. A tenant's fixture, a landlord's riser and a roof defect can each put water in the same ceiling. The practical steps are constant: notify in writing, document every affected space separately, and let each insurer decide its own part.
Begin by telling the property manager and the landlord's engineer in writing, with the time, the suite number and a photograph, then tell your own insurer. Commercial policies differ widely. Ask your agent what yours says about the building, your contents and any cover for lost business while the space is unusable, and treat none of it as settled until the wording says so.
Each affected suite is its own file, with its own photographs, its own moisture readings and its own list of removed material. That structure matters because who pays often differs by suite, and because a tenant below needs evidence of what the water did in its space regardless of where the water began.
Floodwater is a separate subject. Water that enters at ground level from a street or a creek is flood, which a standard property policy may treat differently. Flood cover is a separate purchase, from the National Flood Insurance Program that FEMA runs or from a private carrier, and the federal policies generally wait 30 days before they begin, so cover has to be arranged in a dry month.
What do asbestos and mold rules mean for a commercial building?
Two separate rules apply. Texas calls for an asbestos survey before public or commercial buildings are renovated or demolished, with written notice at least 10 working days ahead of a covered abatement project. Mold work is licensed through TDLR from 25 contiguous square feet, and assessor and remediator have to be separate license holders.
On asbestos, the state program expects a survey before a public or commercial building is renovated or torn down, and an apartment building with more than two dwelling units counts as commercial for that purpose. If a project is covered abatement, written notice is due at least 10 working days beforehand. Single-family homes follow different rules. For anything beyond routine repair, put the question to the state program and your city, ideally before ceiling tile, joint compound or flooring is cut.
On mold, Texas keeps the roles apart. TDLR licenses assessment and remediation as separate jobs, licensing begins once the area reaches 25 contiguous square feet, and no single license holder may do both on one project. Nobody can lawfully sell testing and removal together at that size. The assessor writes the protocol, and a separate remediator carries it out.
The EPA enters as a guideline. Its advice is to start drying water-damaged materials inside 24 to 48 hours; it calls that a guideline, not a deadline, and notes mold may have grown even when materials were dried within that time. What a building owner controls is how fast the water is extracted and whether readings confirm the materials are dry.
