Mold and water damage questions

Fixr's national figures put a typical mold remediation job at $1,500 to $9,000 (about $3,500 on average), or $10 to $30 per square foot. A basement runs $1,500 to $4,000, an attic $1,500 to $9,000, and a whole house $10,000 to $30,000. In New York a job bigger than 10 square feet also needs a licensed assessor, who is paid separately, so budget for the plan and the clearance visit too.

Fixr's national figure for a whole house is $10,000 to $30,000. Most Buffalo jobs are one area, usually a basement ($1,500 to $4,000) or an attic ($1,500 to $9,000). Whole-house jobs tend to follow a flood, a leak that ran for months inside a wall, or a house that sat closed up through a humid summer.

Fixr lists a mold inspection at $450 to $800, about $500 on average, with lab samples at $60 to $80 per sample beyond the first few. Bob Vila puts basic air testing at $250 to $350. In New York the assessment that writes the remediation plan has to come from a licensed mold assessor who will not do the removal.

Fixr lists water damage restoration at $1,200 to $5,000 with a $3,000 national average, and Bob Vila at $1,305 to $5,707. Clean water from a supply line costs less per square foot ($3.75 to $4.25) than sewage ($7 to $7.50). Rebuilding is extra.

New York licenses mold work under Article 32 of the Labor Law, in force since 2016. For jobs larger than 10 square feet, a licensed assessor writes the remediation plan, a separately licensed remediation contractor does the work, and the assessor comes back for a clearance check. The same company may not do both the assessment and the removal on the same property.

Not on the same property. New York Labor Law section 936 bars a licensee from doing both the assessment and the remediation on one property, and bars anyone from owning a stake in both companies on that job.

The NY Department of Labor publishes every mold contractor license on data.ny.gov and updates it daily. Search the business name, then check that the license type fits the job (SH125 is assessment, SH126 is remediation) and that the status says Active.

The state license. A remediation company needs a Mold Remediation Contractor License, and its crew needs individual state licenses. Private certifications are training, not permission to do the work, so ask for the license number first.

Sealing off the area so spores don't travel, removing what can't be cleaned, cleaning what can, then drying the structure and checking that it worked. In New York, a job over 10 square feet follows a licensed assessor's written plan and ends with that assessor's clearance visit.

Almost always. Mold is a moisture problem with a cleanup attached. Fix the water source and remove what can't be cleaned. Clean the rest and dry the structure. Whole-house jobs exist, but Fixr's whole-house figure is $10,000 to $30,000, far below the cost of the house.

There's no federal or New York number for an acceptable indoor level. The EPA's guidance is to clean up mold indoors and fix the moisture, and that if you can see it or smell it, you have a problem. Some spores are always in the air, indoors and out.

Often not. The EPA says that if you can see or smell mold, you have a problem, and sampling usually isn't needed to decide to fix it. In New York the licensed assessor's job is less about lab numbers and more about writing the plan: what gets removed, how, and what counts as clean.

When you smell mold and can't find it, after a leak inside a wall, before buying a house with a damp basement, and on any job over 10 square feet, where New York requires a licensed assessor's plan anyway.

For a small patch, usually yes. The EPA says an area under about 10 square feet is something most people can clean themselves: scrub hard surfaces with detergent and water and dry them. Throw out porous things that stay moldy. New York's license rule also starts at 10 square feet, and homeowners working on their own home are exempt.

The EPA's guidance is detergent and water on hard surfaces, then drying them. Bleach doesn't fix the moisture, and on porous material like drywall or ceiling tile the mold can stay in the material. The EPA warns never to mix bleach with cleaners that contain ammonia.

Nothing in a spray bottle. Mold stops when the material stays dry. Clean or remove the growth, then fix the moisture that fed it. In a Buffalo basement that often means a dehumidifier running from June through September and downspouts that drain well away from the wall.

Drying after a leak usually takes about three days, according to Fixr and Bob Vila. Mold jobs add the assessor's plan before work and the clearance visit after, so plan on a week or more from first call to a passed clearance report, longer if lab results or insurance are involved.

The EPA says to dry water-damaged materials within 24 to 48 hours to prevent mold growth. In a Buffalo basement in July, when the outdoor dew point averages about 61°F and the foundation walls sit cooler than that, wet material does not dry on its own.

Sometimes. New York's Department of Financial Services says mold is covered when it results from a covered event, such as a sudden pipe burst, and that many policies cap what they pay for mold remediation. Mold from long-term seepage or humidity usually is not. Flood needs a separate flood policy. Sewer or sump backup usually needs a water backup endorsement.

New York's warranty of habitability (Real Property Law 235-b) requires landlords to keep a rental fit to live in and free of conditions dangerous to life, health or safety. Tell the landlord in writing first, with photos and dates. Inside Buffalo, investor-owned singles and doubles also fall under the city's 2020 Proactive Rental Inspections law, which requires a Certificate of Rental Compliance renewed every three years.
