"Mason and Dillon were absolutely wonderful to work with. They were both very wonderful and knowledgeable. They took the time to help us fully understand all the processes for both dealing with insurance and coordinating with the plumbers. They made a very stressful time so much easier and very very appreciative. 5 stars for sure!"

"They came out as scheduled and were able to complete the fence in about 3 days. It included setting posts in concrete and constructing the panels on site as well as two gates, one wider gate in line with outside gate for wheelbarrow entrance and the other narrower and on side close to sidewalk. They also installed wood boards under fence so critters including my dog are discouraged from digging under. Gates have nice latches including a wire loop on the inside to pull the latch open when exiting. I was very pleased with the result. They were respectful of the existing plants and raised bed rows taking care not to trample more than necessary."

Foundation Drain Installation FAQs, answered by experts

Yes, you can install a sump pump yourself. By following the steps above, you can have a sump pump installed in 24 hours. You will have to use some advanced tools and techniques, so if you feel uneasy about taking it on yourself, it’s best to hire a professional.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

Costs range from $2,000 to $7,000, depending on system type and excavation requirements.

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.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.
