What is moisture intrusion and water damage?
“Moisture intrusion” means water – whether liquid, frozen, condensed or vaporized – that penetrates into your home. “Water damage” means damage or harm caused by moisture intrusion that reduces the value or
usefulness of your home.
How does moisture intrusion and water damage occur?
Some causes of moisture intrusion and water damage are:
Non-working interior ventilation systems
Missing or loose roofing materials or flashing
Window sills or door frames without adequate caulking or weather-stripping
Lack of caulking in siding, mortar in masonry, or grout in exterior ceramic tile installations
Degraded paint on exterior siding or surfaces
Overflowing or clogged gutters
Gutter drains or downspouts that are not a sufficient distance from the structure
Improper drainage slope next to foundation
Plant materials too close to the structure or foundation
Sprinklers that overspray onto the structure or foundation
How can you tell if your home has water damage?
Signs of water damage may include dampness, staining, mildew (blackened
surfaces with a musty smell), or softness in wood (a possible sign of dry rot).
What to do if you see signs of water damage:
If water damage is discovered, you should investigate its source. Take steps to repair
or replace any building parts or materials that allowed the moisture intrusion. You may need to take additional steps, depending on the
extent of the water damage.
If you have specific questions about maintaining your new home, ask your contractor. If you need professional assistance in conducting
a maintenance inspection, you may wish to contact your contractor or a licensed home inspection business.
