FAQs About Waterproofing
Waterproofing is not always necessary, but it can be a great way to protect your home from moisture and damage. Water seeps through cracks in the walls, ceilings and floors even if they are properly sealed. A waterproof membrane will prevent this moisture from entering your house and causing damage.
Waterproofing your home can help to protect it from water damage in case of a leak, rainstorm or other weather-related event. Waterproofing also helps keep moisture and mold out during cold months when indoor humidity is high. Additionally, waterproof paint provides an extra layer of protection against fading and peeling over time.
It’s always best to be waterproof from both inside and outside, but it depends on the type of water damage that you are experiencing. If your home is flooded or there has been a leak, then you should definitely waterproof it from inside. Otherwise, if just some areas of your home have been wetted down by rain or sprinklers, spraying down those specific areas will be enough.
Most home builders recommend waterproofing your basement every five to ten years, but it depends on the type of soil and construction materials used.
