"DP Plumbing and his crew went above and beyond to make sure that this job was done correctly and for the most reasonable price possible. They were professional efficient and got the job done as quickly as possible. I would highly recommend this company to my friends and family and to anyone else who wants a fair price and a professional team working at your home. I had other people come out and give me bids and none of them gave me the Comfort level that this company did. I just trusted them. I am actually having some other work done and have their card because I'm going to give them a call back for sure."

"Meyer construction did everything for me. They smoothed out my yard, removed a lot of brush, put down a few inches of dirt, and then laid the sod all for a reasonable amount! I would definitely use them again! Job well done. Very friendly to work with also. You will not go wrong with using this company!"

Foundation Drain Installation FAQs, answered by experts

DIY is possible for small systems like French drains. Professional installation ensures proper grading and long-term effectiveness.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.
