Mold staining on attic roof decking beside a roof leak

The newest housing in Collin County, and its own mold problems

Frisco is the youngest big city on our list. The Census Bureau’s July 2025 estimate puts it at 236,955 residents, up 18.2% since 2020, and the ACS 2024 5-year survey gives a median year built of 2009 across 77,208 occupied homes. Only 1.5% of those homes predate 1980, and 65.9% are owner-occupied.

That means almost no cast-iron drains or asbestos ceiling texture. It also means two-story plans with the air handler in the attic, builder-grade flashing, big roofs that took hail on April 11, 2016 (Frisco was one of the four cities hardest hit, with Plano, Wylie and Allen), and attic water lines that froze when DFW hit minus 2 °F on February 16, 2021.

Frisco sits about 12 miles northwest of central Plano and spans Collin and Denton counties. The mold rules are the same on both sides; permits are not.

Where mold turns up in a 2000s and 2010s Frisco home

These are the patterns the companies we connect you with see most in newer two-story construction. They are general building-science explanations, not a statistic for Frisco.

Attic air handlers and condensate

North Texas air conditioning runs for months with summer dew points in the mid-60s °F. A clogged primary condensate line or a rusted secondary pan drips onto ceiling drywall and insulation for weeks before a stain shows downstairs.

Hail-bruised roofs and flashing

Shingles that survived 2016 or the spring 2024 storms (FEMA DR-4781 covers Collin County) can still leak slowly at valleys, pipe boots and chimney flashing. Attic insulation hides the water until the decking stains.

Frozen lines from Winter Storm Uri

Attic and exterior-wall supply lines split during the 139 straight freezing hours in February 2021. Many homes were dried quickly and never opened up, so a musty smell with no visible leak is a common scenario five years on.

Stacked bathrooms

Two-story plans put wet rooms over wet rooms. A slow shower pan leak upstairs wets the ceiling below, and an exhaust fan that vents into the attic adds humidity where it does the most harm.

Oversized AC

A unit too large for the house cools fast but never runs long enough to dry the air, so indoor humidity drifts above the 60% ceiling the EPA recommends.

Builder defects

Window and door flashing that never sealed is a newer-home problem. If a builder warranty still applies, have the assessor document the water path in writing before tear-out.

How a licensed mold job works in Frisco

Texas requires more paperwork than most states, and it protects you. For any hired job of 25 contiguous square feet or more:

  1. Licensed assessment and protocol

    A TDLR-licensed assessment consultant maps the moisture and writes a protocol specific to your house. TDLR says species testing is usually unnecessary, and the EPA says sampling is usually unnecessary when mold is visible.

  2. Remediation by a different company

    Under Occupations Code 1958.155 the assessor and the remediator may not be the same company or share an owner. The remediation company notifies TDLR five days ahead (next business day in a water emergency), builds containment and runs HEPA filtration while it removes the material.

  3. Clearance by the assessor

    The assessor returns while containment is still up, checks the work against the protocol and issues a passed clearance report.

  4. Certificate of Mold Damage Remediation

    Due within 10 days on TDI form MDR-1. Ask for it by name. Insurers may not base underwriting decisions on remediated damage it documents (Insurance Code 544.303), and sellers must give buyers copies for five years.

What it tends to cost. Typical published ranges, not quotes: $10–$25 per square foot (This Old House 2026; Fixr 2025), $1,000–$4,000 for an attic, $500–$1,500 for a bathroom, and $303–$1,044 for a separate licensed assessment (HomeAdvisor 2025). Frisco quotes come from the companies, not from this site. The cost guide explains the four-part Texas cost structure.

Before you hire in Frisco

  • Verify both licenses at tdlr.texas.gov/LicenseSearch, the assessor’s and the remediator’s.
  • Ask for the Consumer Mold Information Sheet, proof of $1 million liability insurance and the written protocol before work begins.
  • Call your insurer early. Sudden and accidental water, such as a burst pipe, is usually covered; a long-running leak usually is not, and many policies cap or exclude mold remediation unless endorsed. Report hidden losses within 30 days. Nobody can promise coverage.
  • Any roof, plumbing, HVAC or wall rebuild that follows needs a City of Frisco permit pulled by that trade contractor; confirm with the city.

Frisco mold questions

Why does a Frisco house built after 2005 already have mold?

Age is not the trigger, water is. Frisco’s median home was built in 2009 (ACS 2024 5-year), so the usual causes are an attic air handler with a clogged condensate line, a window or roof flashing detail that never sealed, a hail-bruised roof, or a supply line that split in the February 2021 freeze. Ask the assessor to map the moisture before anyone quotes removal.

Do I need a licensed company for a small patch of mold in Frisco?

If the affected area is under 25 contiguous square feet, Texas lets you clean it yourself or hire anyone. At 25 square feet or more, hired work needs a TDLR-licensed assessor for the written protocol, a different licensed remediation company for the work, a TDLR notification five days ahead (next business day after a water emergency), containment, a clearance assessment and a Certificate of Mold Damage Remediation within 10 days.

Is Frisco in Collin County or Denton County, and does it matter?

Frisco straddles both. The Texas mold rules are state rules, so the licensing, protocol and certificate steps are identical on either side of the county line. What changes is who issues permits for any plumbing, roof, HVAC or wall rebuild that follows: that is the City of Frisco building department, not the county, so ask the trade contractor to confirm before work starts.
