Most of the houses in McKinney are young. The Collin County seat had about 54,000 residents in 2000 and more than 195,000 by the 2020 census, so a large share of today's homes, shopping centers and apartment complexes went up in the last two decades. Newer construction does not mean drier construction, though. Supply lines, water heaters, washing machine hoses and roof penetrations installed in the same building boom tend to reach the end of their service life around the same time, and a single failed fitting upstairs can soak two floors before anyone notices.

Wilson Creek, Lavon Lake and Blackland Prairie Runoff
Wilson Creek rises east of Celina and runs about 23 miles southeast through McKinney, passing under U.S. 380 and State Highway 75 before it meets the East Fork of the Trinity River at Lavon Lake. Smaller tributaries and drainage channels feed it from neighborhoods all over the city. During a slow-moving spring storm, those channels can rise quickly, and yards that back onto them collect water that has nowhere else to go.
The heavy, clay-rich soils of the blackland prairie make this worse. Once the ground is saturated it sheds water like pavement, so runoff pools against foundations, finds gaps around door thresholds and seeps under garage slabs. May is the wettest month on average, with roughly 5.7 inches of the city's 41 inches of annual rain. Before you buy or remodel near a creek, look up the parcel on the FEMA flood map, and remember that a standard homeowners policy does not cover rising water. Flood coverage is a separate policy with its own waiting period.
Tornadoes and Severe Storms in Collin County
Severe weather has a long record here. A tornado struck McKinney on May 3, 1948, killing three people, injuring 43 and causing about $2 million in property damage at the time. Much more recently, on May 9, 2006, a tornado tracked through Anna, Westminster and Van Alstyne in northern Collin County, and the same storms dropped hail up to golf ball size.
Wind and hail damage becomes water damage when the next rain arrives. Lifted shingles, cracked skylights and broken windows let water into attics and wall cavities, where it can soak insulation for days without showing on the ceiling. After a storm, a provider offering storm damage cleanup can tarp openings, remove wet insulation and check framing with moisture meters before drywall is closed back up.
Ice Storms, Long Freezes and Plumbing in Newer Homes
North Texas winters are usually mild, which is exactly why hard freezes catch people off guard. During the January 23 to 26, 2026 winter storm, the National Weather Service recorded 58 consecutive hours at or below freezing at DFW Airport along with sleet, snow and freezing rain across the region. Pipes running through exterior walls, attics and unheated garages are the usual failures. Many split while frozen but do not leak until the thaw, so the damage often shows up a day or two after the storm passes.
- Know where your main shutoff is before a freeze. In many McKinney homes it sits in a box near the curb or in the garage.
- Open cabinet doors under sinks on outside walls and let faucets drip during long freezes.
- Check the attic and the garage ceiling once temperatures rise above freezing.
- Photograph damage before cleanup begins, for your insurance claim.
Older Buildings Around the Downtown Square
Historic downtown is a different story from the newer subdivisions. The Old Collin County Courthouse dates to 1876 and now houses the McKinney Performing Arts Center, and many of the commercial buildings around the square are of a similar vintage. Masonry walls, older roofs and shared party walls between storefronts mean that a leak in one building can show up in the next one over. Owners of older properties should ask a restoration provider about drying methods that avoid unnecessary demolition of original plaster, trim and wood floors.
Drying Out Before Mold Gets Started
Humid summers and warm spring nights give mold an easy start once drywall, carpet pad or cabinet bases stay wet. Growth can begin within a couple of days, which is why fast removal of standing water and steady drying matter more than any cleaning product. A typical job involves extracting water, removing pad and saturated drywall where needed, then running air movers and dehumidifiers while readings are taken each day until materials return to normal.
If musty odors or spotting appear after an earlier leak, professional mold cleanup focuses on finding the moisture source first. Removing visible growth without fixing the leak only buys time.

Frequently Asked Questions
My backyard backs onto a creek in McKinney. Am I in a flood zone?
Possibly. Wilson Creek and its tributaries run through much of the city, and mapped flood areas follow those channels. The FEMA Flood Map Service Center shows the official zone for any street address. Even outside a mapped zone, clay soil and heavy spring rain can push water against a slab, so a separate flood policy is worth pricing, especially since it usually has a waiting period before coverage starts.
Pipes froze during a winter storm but nothing is leaking. Am I in the clear?
Not yet. Frozen pipes often crack while full of ice and only start leaking when they thaw. After a hard freeze, check walls along the north and west sides of the house, the attic, the garage and any outdoor hose bibs once temperatures climb. If you see water, shut off the main valve and call for help before the wet area spreads into flooring and cabinets.
Does a newer McKinney home really need professional drying after a leak?
Newer homes are built tighter, with more insulation and less air movement, so trapped moisture can linger inside walls and under laminate or engineered wood. A box fan dries the surface but not the cavity behind it. Providers use moisture meters and thermal cameras to find where water travelled and set up equipment to dry those areas, which helps prevent mold and swelling later.
Who do I call if storm damage lets water into my house at night?
Call (888) 317-9980 at any hour. The Restoration Job is a referral service, so we connect you with an independent restoration provider that serves McKinney. Many providers in the area offer emergency service for tarping, water removal and drying. If wires are down or water is near outlets, keep clear and contact your utility or 911 first.
