"I had fascia damage where the sloped roof met the flat roof. They repaired both the damage and repaired the roofs. They showed up as promised on time. They are very careful about cleaning up cleaning both during and after the work."

"Apex Plumbing employees, James and Zach, came to my house to repair a water leak that stopped all water service to my house. James came and cleared the lawn covering my pipes. Then Zach came, located the leak and replaced the water pipe serving my house. Unfortnately, The meter showed a continuing leak. James crawled under my house and found an unknown second leak. They eliminated that pipe leak under my house. I now have full water service to my house with no more leaks. Thank you Zach and James for a complete repair of known and unknown leaks. Good job!"

"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."

Basement Waterproofing FAQs, answered by experts

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.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

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.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.
