What Boulder's homes say about water damage
Boulder's housing spans several generations: more than half homes predate 1980, while about one in six were built in 2000 or later. That means the likely cause of a leak depends a lot on the house. Older homes tend to have corroded supply pipe and cracked drains, while newer homes see more failures at hoses, fittings and water heaters.
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.
About 38% of homes in Boulder are in buildings with five or more units. In apartments and condos, water from one unit often reaches the unit below, so tell management or the HOA right away. The building's master policy and your own unit or renters policy may each cover a different part of the damage.
Many homes here are older, and a large share of residents rent near the University of Colorado.

Weather and ground risks around Boulder
The Colorado Front Range
See the full list of regional water risks, and every city we cover nearby, on our Colorado page.
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 Boulder
How quickly does water damage need to be dried in Boulder?
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 Boulder?
It depends on the age of the home. In Boulder'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.
