What Longmont's homes say about water damage
Longmont's housing spans several generations: about a third homes predate 1980, while about four in ten were built in 2000 or later. Older homes here are more prone to corroded pipe and failing drains, and newer ones to appliance and fitting leaks, so a good restoration company starts by finding the source rather than assuming it.
With so many homes built over basements or crawl spaces, the lowest level is where water ends up, whether it comes from a burst pipe upstairs or seepage through the foundation.
Vrain River flooded parts of Longmont in September 2013, and the city has since rebuilt flood channels along it. Basements, window wells and frozen pipes are the most common sources of damage.

If water is coming in right now
- Stop the water. Close the valve at the fixture, or the main shutoff for the house.
- Make it safe. Cut power to wet rooms at the breaker only if you can reach the panel without standing in water.
- Protect what you can. If water is in a finished basement, move furniture, boxes and electronics to a dry level and keep everyone off wet carpet near outlets and appliances.
- Photograph it, then get drying started. Photos come first for insurance; drying should begin the same day. Our first 24 hours guide has the full checklist.
Where the main shutoff usually is
Front Range homes usually have the main shutoff in the basement or crawl space where the line comes through the foundation wall, often near the water heater.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

Water damage questions from Longmont
How quickly does water damage need to be dried in Longmont?
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Hidden moisture inside walls and under floors needs meters and drying equipment to find and remove.
What is the most common cause of water damage in Longmont?
It depends on the age of the home. In Longmont's older houses, corroded pipe and cracked drains are common. In newer homes, appliance hoses, water heaters and fittings cause most sudden leaks. Storms and roof leaks add to both.
