What February 2021 taught Princeton
During the February 2021 winter storm, The Dallas Morning News reported that Princeton issued a boil water notice: the system did not have enough supply, or the power to run its pumps. The notice was lifted later that week.
Across North Texas that week, DFW Airport stayed at or below freezing for 139 hours and dropped to minus 2 degrees, and pipes split in attics and outside walls. When pressure came back, a lot of homeowners found the damage all at once: a ceiling giving way, water running down inside a wall, a garage floor covered in water from a split line.
That is the main lesson for water damage restoration in Princeton. Know where your main shutoff is before the next hard freeze, and know who to call when the water starts.

A town that more than doubled
The city's demographics page lists 3,477 residents in 2000, 6,822 in 2010 and 17,027 in 2020. Census Bureau estimates released in 2025 named Princeton the fastest growing city in the country. Growth came so fast that in September 2024 the City Council voted to pause new residential permits for a time, citing water, wastewater and roads at or beyond capacity; that pause has since expired.
So most Princeton houses are recent builds on slabs over Collin County's shrink-swell clay. When they leak, it is usually at a fitting, an appliance, a water heater in the garage, an upstairs bathroom or an AC drain line, or under the slab as the soil moves through wet and dry spells. A plumber stops and repairs the leak. A restoration company finds how far the water spread, dries it and removes what cannot be saved.

Water Extraction and Emergency Water Removal
Standing water from a supply line, water heater or storm: what extraction equipment does, carpet and pad decisions, and why drying has to follow.

Flood Damage Restoration
Rising water from creeks, streets and the Trinity is Category 3. What flood cleanup involves, how to read a FEMA flood map, and why a home policy is not a flood policy.

Water Damage Repair
Putting a house back together after the drying is done: drywall, floors, cabinets and paint, who does each part, permits in Dallas and the paperwork your insurer will want.

Lake Lavon, Sister Grove Creek and rising water
Princeton sits near Lake Lavon, an Army Corps of Engineers reservoir built for water supply, flood control and recreation. The Princeton Herald reported that on June 14, 2021, the lake stood at 500.39 feet, 8.39 feet above its normal level of 492 feet. Sister Grove Creek runs through the area too, and the US Geological Survey keeps a gauge on it at FM 1377 near Princeton.
The IICRC S500 standard puts lake, creek and street water in Category 3, its most contaminated grade. Treat it as if it carries sewage, keep children and pets away from it, and expect the company to replace soaked carpet, pad and lower drywall rather than dry them. A standard homeowners policy does not cover this kind of flooding.

Safety first. Shut off the main water valve if you can get to it without risk. Water and electricity together are the real hazard, so stay out of any puddle that touches an outlet, a cord or an appliance. Switch off the breaker only when the panel can be reached from dry flooring; if it cannot, call Oncor or Texas-New Mexico Power (whichever is on your bill) or an electrician. A gas smell means everyone goes outside, and the calls to 911 and the gas company on your bill are made from there. Floodwater and sewage are not safe to wade through, for adults, children or pets. Once everyone is safe, take photos for the insurance claim and carry valuables and documents to a dry room.
Permits in Princeton: do not close the walls too soon
Princeton's Building Inspection Division issues permits for additions and remodeling and enforces the building, electrical, plumbing, mechanical and fuel gas codes. Foundation repair needs a Foundation Permit with stamped engineered plans, and replacing windows or doors needs a Remodel Permit. The rule that matters most after water damage: permitted work has to stay exposed until it is inspected and approved.
- Ask before demolition which repairs will need a Princeton permit and who will pull it.
- Keep moisture readings from the first day and the last, so you can show the walls were dry before they were closed.
- Do not let new drywall go up over permitted plumbing or wiring until the inspection is done.
- If mold appears, ask how big the area is. Texas rules generally call for licensed professionals at 25 contiguous square feet or more; look the names up on the TDLR license search.

How a Princeton call works
Water Damage Pro Dallas is a free phone line for Dallas-Fort Worth. It does not dry, clean or repair anything. It answers, finds out what you are dealing with and connects you.
- Call the numberAn automated assistant answers (469) 649-7066 at any hour and asks what you need help with. The same number answers other home service calls too, so start with "water damage" or "mold".
- Describe what happenedA burst pipe, standing water, a wet ceiling, a slab leak, a sewage backup or mold, plus your town and whether water is still coming in.
- Get transferredWater damage calls go to an independent, locally owned DFW restoration company; mold removal calls go to an independent mold remediation company. Each hears a short summary before it picks up. Mold testing calls are taken as a message for now.
- Deal with that company directlyIt inspects, quotes and does the work, and you pay it (or your insurer does, as you arrange). If it cannot answer, it gets your name, number, city and problem so it can call you back.
Say Princeton, Texas, then what is leaking and whether it has stopped. The company you are put through to visits the house, and any price comes from that company in its own estimate.
