Why mold is common in Spring
Spring is an unincorporated community in north Harris County, bounded by Spring Creek, which forms the line with Montgomery County. NOAA's 1991–2020 normals for Houston show about 56 inches of precipitation a year, with June, September, and October the wettest months.
Cypress Creek runs through the heart of the area. During Hurricane Harvey in 2017, 29.3 inches of rain fell across its watershed in four days, causing record flooding from US 290 east to where Cypress Creek meets Spring Creek, and 9,450 homes in the watershed flooded, according to the Harris County Flood Control District. The Tax Day flood of 2016 had already flooded more than 1,700 homes there. Neighborhoods in Spring and Klein hit hard include Ponderosa Forest, Westador, Champion Forest, and Wimbledon Champions. As more land in the watershed was developed, from about 18% in 1996 to as much as 52% in 2018 by regional estimates, more rain runs off instead of soaking in.
Away from the creeks, most homes are slab-on-grade with air handlers and ducts in the attic, where condensation and overflowing drain pans are common sources of hidden moisture. The EPA recommends drying wet materials within 24 to 48 hours to keep mold from taking hold.

Spring prices follow the Houston market, so the table uses Houston contractor guides from 2026 and a 2025 Houston guide for per-foot pricing. About 30% of homes here were built before 1980, per Census ACS 2020–2024, and an older house that has flooded more than once may need more demolition than a newer home with a single leak. Ask for a written protocol first; it lets you compare contractor bids line by line. See the cost guide.
Texas mold licensing: what to check
Spring has no city government of its own, so the state license is the main credential to check. Texas requires a TDLR-licensed remediation contractor for mold covering 25 contiguous square feet or more, plus a separately licensed consultant to write the protocol and do the post-remediation assessment. One license holder may not do both on a single project.
Since September 1, 2025, every employee doing assessment or remediation has needed a TDLR license or registration. Look up names at tdlr.texas.gov, expect the Consumer Mold Information Sheet before the job, and keep the Certificate of Mold Damage Remediation, which the contractor must provide within 10 days. If you sell, Texas requires handing buyers the certificates issued in the past five years.
Will insurance cover it?
Along Cypress Creek, the Harris County Flood Control District counted 9,450 homes flooded in Harvey and more than 1,700 in the 2016 Tax Day flood, and none of that water is covered by a standard homeowners policy. Flood coverage is a separate purchase, and a new NFIP policy usually has a 30-day waiting period, per FEMA. If your street flooded in either storm, price a policy now rather than when the rain starts.
Inside the home, the Texas Department of Insurance says a typical policy covers sudden and accidental water, such as a supply line that bursts, and mold on belongings that water damaged. Slow roof or plumbing leaks usually are not covered, and many policies cap mold claims at a set dollar amount. Read your mold endorsement, and see does insurance cover mold.
