"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

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.
