Seeing mold right now? Do this first
- Leave it alone. Scrubbing, spraying bleach, or sanding dry mold throws spores into the air.
- Close the room. Shut the door and, if you can, the HVAC vent in that room.
- Find the water. Mold means moisture. Look for a leak, a wet wall, or a sweating duct.
- Measure it. Estimate the size. Patches of 25 contiguous square feet or more fall under Texas mold rules.
- Call us. Reach us at (940) 274-9880 to schedule an inspection.
Local conditions
Why mold grows in Lewisville homes
Lewisville is a lake town. The city sits at the south end of Lewisville Lake and the LLELA nature preserve along the Elm Fork. On long, humid summer days, indoor humidity can climb when an air conditioner is short-cycling or oversized, and that is all mold needs on a surface that is already damp.
Housing age plays a part too. With so many homes here built in the 1980s and 1990s, original shower pans, window seals, and attic condensate lines are aging. Small, slow leaks behind tile or inside a wall are the most common starting point for hidden mold.
Apartments and townhomes, which make up a big share of local housing, can pass moisture through shared walls and ceilings.

The process
How professional mold remediation works
Inspect
We map moisture, look behind surfaces with a thermal camera, and find the water source.
Contain
Plastic sheeting and zip doors seal the work area. A negative air machine keeps spores from drifting into clean rooms.
Remove
Moldy drywall, insulation, and carpet are bagged and taken out. Framing is cleaned or sanded.
Clean the air
HEPA vacuums and HEPA air scrubbers capture spores. Surfaces get wiped and treated with antimicrobial.
Dry and verify
We confirm materials are dry. On larger projects, an independent assessor performs clearance.
Texas mold rules in plain language
Texas regulates mold work through the Texas Department of Licensing and Regulation. Here are the points that affect you most:
We will tell you where your project falls and coordinate with an independent mold assessment consultant when the rules call for one. The TDLR mold program has the full rules and a consumer sheet.

Mold remediation cost and insurance
Price depends on the size of the affected area, what material it is on, how hard it is to reach (attics and crawlspaces take longer), how much containment is needed, and whether an outside assessor is required. Mold on drywall behind a vanity is a very different job from mold across a whole attic deck.
Insurance is the tricky part. Many policies cover mold only when it results from a covered, sudden water loss, and some cap mold payouts at a low limit. Mold from long-term humidity or a slow leak is often excluded. Our mold growth risk calculator helps you judge how urgent your situation is.

FAQ
Mold remediation questions from Lewisville
Can I clean a small mold spot myself?
A few square feet on a hard surface can often be cleaned with detergent and water while wearing gloves and a mask. If it keeps coming back, covers a large area, or is inside walls, get professional help.
Do I need mold testing before remediation?
Not always. Visible mold with a known cause does not always need lab testing. Larger projects under Texas rules require an assessment by a licensed consultant, who may take samples.
Does living near Lewisville Lake mean I will get mold?
No. Lake humidity makes drying slower, but mold still needs a damp surface. Keeping indoor humidity below about 50% and fixing leaks quickly prevents most problems.
How long does mold remediation take?
Small jobs can be done in a day or two. Larger projects with containment, removal, drying, and clearance testing often take several days to a week or more.
Is it safe to stay home during remediation?
Usually, yes, because containment and negative air keep the work zone separate. People with asthma or allergies may want to stay elsewhere during removal.
Will you fix the leak that caused the mold?
We find the moisture source and dry the structure. If the cause is a plumbing, roof, or AC problem, a licensed trade repairs it, and we coordinate so the fix happens before walls are closed.
