"Alpha Foundations in addition to adding pilars around the exterior and doing a great job, I inquired about concrete foaming. They immediately got me in contact with their concrete foam team Bradley and John. Bradley did a great job and took the time to explain everything to me. I asked how big will the size of the drill hole be and he said M&M size (plain M&M). I am thrilled I got this done and feel safe in my home. It was amazing how the foam raised the slab which raised the kitchen floor and no more gaps between the backsplash and counter."

"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."

"Had a great experience with this company! Estimate and scope of work was clear, the price was fair, and Bryce and Jose went above and beyond to reroute my dryer vent inside of an interior wall and away from the waterproofing area! Definitely would recommend"

Basement Waterproofing FAQs, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’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.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
