Why does my basement leak after heavy rain?

• <div><p>If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.</p></div>

Q: How long does it take for water to cause structural damage?

• <div><p>Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they&rsquo;ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.</p></div>

Q: Do services include waterproofing or UV protection?

• <div><p>Yes, many repair services include reapplying waterproofing and UV-resistant coatings.</p></div>

Q: How can I prevent ductwork from sweating in a crawl space?

• <div><p>Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.</p></div>

Q: How do I make good drainage around my house foundation?

• <div><p>The best way to ensure the ground next to your home&rsquo;s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil. </p></div>
