"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."

"Called Dean with an emergency on a raining Sunday after turning to Angieâ s List to get my sump pumps working. Had never used him before. He came immediately. He got 2 of 3 working and replaced the third. Got everything set back up and running. Charged me only $150 ona Sunday plus the cost of the new sump pump, which was about the same as the last time I got a new pump from a plumber. Knows his stuff, friendly and reasonable. Would definitely recommend."

"Flooding in our basement has been a recurring problem over the years. We’ve had various companies do work for us but they failed to keep our basement dry for longer than a few months at a time and only did a semi okay job. That all changed when we hired Empire Construction Waterproofing. Chris gave me a very reasonable price for the size of our project. They had a team down there starting to work almost right away! They were incredibly professional and worked very efficiently. Once they were done they left the space in great condition. My husband and I were very satisfied with the project. The results went above and beyond our expectations, the quality was unlike anything we’ve ever seen before. It was such a pleasure working with Chris and Empire Construction Waterproofing. I have recommended them to all of my friends and family. If you’re having basement issues definitely give them a call."

Basement Waterproofing questions, answered by experts

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
