Mold Remediation in Wylie, TX
On April 11, 2016, hail hit about 80% of the homes in Wylie. Nearly a decade later, those roofs, attics and ceilings are still a big share of the mold calls here. Plano Mold Experts is a free quote service that connects Wylie homeowners with independent, TDLR-licensed mold assessment and remediation companies. We do not do the work ourselves.

April 11, 2016
A supercell that stretched roughly from Wichita Falls to Tyler peaked over Collin County. The National Weather Service recorded that 80% of Wylie’s homes were affected and that damage in the city alone passed $300 million. Plano, Frisco and Allen were hit the same evening.
2016 to 2017
Most of the city re-roofed at once: a rush of crews, and a lot of flashing, pipe boots and valley metal reset in a hurry.
February 2021
Winter Storm Uri held DFW below freezing for 139 straight hours, bottoming at minus 2 °F on February 16. Attic water lines split across Collin County; homes dried fast and never opened up are a common hidden-mold scenario today.
Spring 2024
Severe storms, straight-line winds and flooding brought a federal declaration (FEMA DR-4781) covering Collin County, and tested every 2016 roof again.
Now
A nine-year-old roof with a small flashing leak, insulation that soaked it up, and a ceiling stain that finally shows. See attic and roof leak mold.
Lake-country humidity and 2000s tract homes
Wylie sits between Lavon Lake and Lake Ray Hubbard, with Lavon Dam about five miles north of town, roughly 9 miles east of central Plano. The Census Bureau’s July 2025 estimate is 63,842 residents, up 11% since 2020, after a run from 8,716 in 1990 to 57,526 in 2020. The ACS 2024 5-year survey gives a median year built of 2006, 7.0% of homes predating 1980, and the second-highest owner-occupancy on our list at 77.4% of 18,701 occupied homes.
That is a city of slab-on-grade two-story tract homes built in one short burst on Blackland Prairie clay, with the air handler in the attic. Beyond the roofs, the companies see condensate pans overflowing onto ceilings in July, slab leaks on lines stressed by clay movement, and bath fans that empty into the attic. Downtown Wylie was also hit by a tornado on May 9, 1993, so the older core near the rail line has a longer repair history.
What to do today if you found it
Stop the water, even if that means shutting the main. Photograph the stain, the mold and the leak before anyone cleans. Do not scrub a large area: Texas sets the hired-work threshold at 25 contiguous square feet, and a DIY job that grows past it loses the exemption. Keep kids and pets out of the room, run the AC, see a doctor if anyone has symptoms, then request quotes.
What a licensed job looks like in Wylie
For 25 square feet or more, Texas requires two companies that cannot share an owner: a TDLR-licensed assessment consultant who writes the protocol, and a licensed remediation company that notifies TDLR, contains the area, runs HEPA filtration and removes the material. The assessor returns for clearance, and the Certificate of Mold Damage Remediation (TDI form MDR-1) is due within 10 days. In a town with Wylie’s claims history that certificate matters: insurers may not base underwriting decisions on remediated damage it documents, and buyers must receive copies for five years.
Typical published ranges, not quotes: attic $1,000–$4,000 (This Old House 2026), $10–$25 per square foot overall, bathroom $500–$1,500 (Fixr 2025), separate licensed assessment $303–$1,044 (HomeAdvisor 2025). Wylie quotes come from the companies. More in the cost guide.
Hail and burst-pipe water is usually the “sudden and accidental” kind policies cover; a roof that dripped for two years usually is not. Many policies cap or exclude mold remediation unless endorsed, so check your declarations page and report hidden losses within 30 days. A roof replacement or any plumbing or wall rebuild needs a City of Wylie permit pulled by that contractor.
Wylie mold questions
My Wylie roof was replaced after the 2016 hail. Can it still be leaking?
Yes. A roof installed in 2016 or 2017 is now nine or ten years old and has been through the spring 2024 storms. Slow leaks at valleys, pipe boots, satellite mounts and chimney flashing are the usual culprits, not the shingles themselves. Attic insulation absorbs the water, so the first sign is often staining on the roof decking or a brown ring on an upstairs ceiling months later.
Does living between two lakes make mold more likely in Wylie?
Outdoor humidity is high across North Texas in summer, with dew points typically in the mid-60s °F, and Wylie sits between Lavon Lake and Lake Ray Hubbard. The EPA’s guidance is the same everywhere: keep indoor humidity below 60%, ideally 30 to 50%, and dry wet materials within 24 to 48 hours. An AC system that keeps up does that; a clogged condensate line, an oversized unit or a closed-up vacant house does not.
Is a free quote the same as a free inspection?
No. We offer free quotes, meaning independent companies reply with pricing and a proposed approach at no charge. A licensed mold assessment is a paid service by a TDLR-licensed assessment consultant, typically $303–$1,044 (HomeAdvisor 2025), and it produces the written protocol a remediation company must follow on any job of 25 square feet or more. Be wary of door-to-door “free inspection” offers after storms; Texas gives you three business days to cancel a door-to-door sale.
