Get matched with top basement waterproofing pros in Wolfeboro, NH

Q: Can a leak outside cause damage to your house?

• <div><p>Yes, outside leaks can easily cause damage to your home if you don&rsquo;t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home&rsquo;s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.</p></div>

Q: Is it better to have a crawl space or a slab?

• <div><p>Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn&rsquo;t an issue because they&rsquo;re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue. </p></div>

Q: How much does it cost to finish a crawl space?

• <div><p>If you don&rsquo;t wish to dig it out and convert it into a finished basement, you can still <a href="https://www.angi.com/articles/how-much-does-crawl-space-encapsulation-cost.htm">encapsulate your crawl space</a> to protect it from damage for an average cost of <b>$5,500</b>. Finishing a crawl space beyond this isn&rsquo;t really worthwhile, as the low ceilings mean you won&rsquo;t be able to use the area as living space.</p></div>

Q: Can water seep through cracks in the basement floor?

• <div><p>Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don&rsquo;t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.</p></div>

Q: How do you seal a leaky concrete slab?

• <div><p>You can <a href="https://www.angi.com/articles/how-to-seal-concrete.htm">seal a concrete slab</a> by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.</p></div>
