5 Areas Of Your Home To Waterproof

Water damage can be one of the most destructive forces in a home. Water seeping into walls, floors, and other structures can cause mold, rot, and deterioration, and lead to very expensive repairs. That’s why it’s critical to waterproof key areas of your home to prevent water intrusion and damage. Here are 5 key areas to focus your waterproofing efforts.


The basement is one of the most vulnerable areas for water intrusion. Being underground, basement walls and floors are subject to hydraulic pressure from surrounding soil and groundwater. Moisture can seep in through cracks and pores in the concrete. In addition, items stored in basements are at risk of water damage during heavy rains or flooding.

To waterproof your basement, apply a concrete sealer to form an impermeable barrier. Also, install a French drain system around the perimeter to collect and divert groundwater before it enters the basement walls. Use waterproof paints on any exposed wood framing. Ensure downspouts direct rainwater away from the house foundation as well. With proper basement waterproofing, you can turn this space into a pleasant, usable living area.

With constant water usage, bathrooms contain many sources of potential leaks. Damaged or improperly installed toilet seals, leaks around bathtubs and showers, and spilled water can all lead to water intrusion and damage in flooring, walls, and subfloor.

Seal tile grout and caulk around sinks, tubs, showers, and fixtures. Ensure overflow drains are working properly. Replace any damaged or loose tiles or cracks in the flooring. Consider applying waterproof membranes or paints, especially under tile floors and around showers/tubs. Installing drain pans under units and leak detectors can also help minimize damage from unnoticed leaks.


As the most exposed part of the home, roofs take a beating from rain, snow, and other weather. Water that gets past the exterior roofing material can damage the roof deck and leak into the attic and interior spaces.

Inspect roof flashings, valleys, chimneys, skylights, and gutter connections for any worn or missing material. Reapply roof cement or tar as needed. Check for damaged or loose shingles and replace them promptly. For older roofing at the end of its lifespan, consider professional re-roofing to apply modern, waterproof roofing membranes for full protection.

Doors And Windows

Seals around doors and windows can break down over time due to movement, weathering, and wear. This allows air and water intrusion that can lead to damage.

Inspect seals around doors and windows for gaps or cracks. Reapply caulk or weatherstripping as needed to form a watertight barrier. Check that window panes are securely glazed, and replace any cracked or broken panes. Ensure doors have proper overhangs, awnings, or porches above them to divert rainwater. Keeping doors and windows properly sealed is one of the most cost-effective waterproofing measures.
