What Is Water Intrusion?

Water intrusion is excess water accumulation in unwanted places of the house like the roof, the floor, or the walls. It accumulates and slowly damages the structure of the affected area.

This is due to water leaks through any plumbing lines and seeps into the concrete structure of the house.

You may not notice it if the accumulated water is very low. But as water leaks more and slowly accumulate, it starts to show various signs. When you find the problem, it is important to take immediate steps and prevent any further damage.

If you feel that the air has a wet smell even when there is no rain, then there might be a water intrusion in your house.
