Steps in Waterproofing Your House

Water intrusion can take a serious toll on homes, and even small issues can lead to major consequences. Rainwater and ground seepage can ruin a house’s substructures, roof, masonry, and cement, among many others. The best way to prevent water from damaging a home is through prevention. By prevention, we mean waterproofing the entire house not only from exterior sources but from interior sources as well. Sealing and waterproofing chores can go a long way when it comes to protecting houses, and they are fairly easy to do.

Here are some measures to waterproof a house:


Paint is not only used for the aesthetics of a house, but it is also used to seal wood siding from water intrusion. A waterproof deck system applied over plywood is a preventive approach to avoid rotting, cracking, and warping wood. Instead of waiting for things to be broken down, it is best to repaint failing paint and apply wood sealers where necessary.

Reseal Roof Components

The roof is the first line of defense from water damage. Roof components are built waterproof to control runoff and prevent water from getting into the gaps, leaking into the homes, and damaging everything from the attic, the ceiling, to the walls. Constant sun exposure and other harsh elements, however, can cause these waterproofing materials to erode at a drastic pace. Thus, it is important to schedule regular roof inspections and clean the gutters. Adding caulking to roof flashing, apertures, and other points of entry is the most economical roof waterproofing chore.

Seal Cracks and Gaps

Older structures will most likely contain gaps and cracks in their exterior walls, door panels, and window trims. Once a crack develops, it can leave the house’s substructures vulnerable to moisture and further deterioration. Therefore, there is a need to seal these gaps immediately. Do not forget that a house’s solid concrete foundation is still susceptible to water damage because concrete is porous and water can seep through it.

Homeowners should schedule regular inspections around the house to seal all visible cracks with moisture-resistant latex caulk. For larger gaps (more than a quarter-inch in width), a plastic foam filler will do the job thoroughly.

Address Basement Cracks and Window Well Leaks

Just like roofs, builders waterproof basements during construction.  But because they are built below grade level, basements tend to take on moisture and water over time. Also, as cement sets, they shrink, causing floors to literally pull away from the walls. This creates cracks and water entryways.

Humid and damp basements can result in rotten wood, damaged items, mold, mildew, and other biological growth. Understanding where the water is coming from is the first step to addressing the problem. Hydraulic cement and masonry waterproofing products can help fill leaks and even little surface holes. Ventilation fans are another useful tool to control moisture in basements.

It is important to remember that any sealant and waterproofing material wears out over time. Regular inspections are necessary to reapply any caulking that looks worn out. Don’t let water damage your investment.
