Get matched with top basement waterproofing pros in Coventry, NY

Q: Should I pick a topical or a penetrating sealer for my project?

• <div><p>Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.</p></div>

Q: What are the downsides to crawl space encapsulation?

• <div><p>The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.</p></div>

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

• <div><p>Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.</p></div>

Q: How long does crawl space encapsulation last?

• <div><p>Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.</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>
