Water Intrusion in Residential Buildings
Water intrusion is the plain name for water that was supposed to stay out, or stay in a pipe, and did not. It includes a supply-line break, a roof or window leak, and groundwater at a foundation. The word is used in building and insurance conversations, sometimes more formally than 'a leak.' This page is a map. It is residential. It does not diagnose your house from a paragraph. Independent contractors follow the actual path. We refer them.
Three families of intrusion
Plumbing, the building envelope, and the ground.
Plumbing intrusion is water that left a supply, a drain, or an appliance. Use the burst-pipe, bathroom, kitchen, toilet, and sewer pages. Envelope intrusion is a roof, a wall, a window, or a door that let weather in; use roof leak water damage restoration and the storm page. Ground intrusion is water at a basement or crawlspace through masonry, a failed drain, or a grade problem; use the basement, foundation, and crawlspace pages.
The signs of water damage guide helps you notice intrusion early. The causes and prevent pages sit on either side of this one. Category (1, 2, or 3) still applies once the water is in the materials; see category 3 water damage.
Intrusion is a source word; restoration is the response
Stopping intrusion and drying the house are both required. Doing only one of them fails.
A roofer, a plumber, or a waterproofing trade may stop the path. A restoration contractor extracts and dries. Insurance language ('sudden and accidental,' 'flood,' 'backup,' 'seepage') does not always match the building language. See the coverage and claims pages. We check residential contractor availability after a ZIP. We do not promise to find and fix every envelope failure through this network alone.
Frequently Asked Questions
Answers about intrusion versus flood, when to wait, and which trade stops the path.
Not always. In everyday speech people overlap the words. In insurance, flood is often water from outside rising over the ground, and it may need a separate policy. Intrusion can also be a pipe or a roof.
A tiny, stopped, clean drip with no wet cavity might wait a short time, with photos and a watch on the area. An active leak, a sagging ceiling, or dirty water should not wait.
Meters, a look at the room above or the crawl below, a water-meter check, and sometimes a plumber's or roofer's test. See signs of water damage.
Sometimes it reduces a damp spot; often it hides a path that still wets the wall. Chronic foundation water needs a trade that deals with the outside path, not only paint.
