Get matched with top basement waterproofing pros in Longboat Key, FL

Q: How do you keep moisture out of a brick wall?

• <div><p>Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn&rsquo;t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it&rsquo;s more likely that you have a crack or other issue at play that a typical sealant won&rsquo;t fix. So, instead of investing in sealant, try <a href="https://www.angi.com/articles/how-much-does-repairing-brick-wall-cost.htm">repairing your brick wall</a> instead. </p></div>

Q: Can I add a sump pump to an existing basement?

• <div><p>A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.</p></div>

Q: Can you make a crawl space liveable?

• <div><p>Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable. </p></div>

Q: What is the best drainage around a foundation?

• <div><p>Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it&rsquo;s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques&mdash;like soil gradation and gutter and leader installation&mdash;to resolve the underlying problem.</p></div>

Q: What is the safest insulation for basement walls?

• <div><p>Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don&rsquo;t have to worry as much about a fire breaking out as you would with spray foam insulation. </p></div>

"Our neighbor's yard slopes down towards our house. So water kept gathering around our foundation and leaking through after rain storms. This caused mold problems inside. Bullfrog waterproofed the foundation and installed a French drain system with catch basin drains to help move water away from this area of our yard. They also handled the mold and water restoration work on the inside at the same time. Thanks again for taking care of everything for us at a difficult time."
