"The representative who initially came to the house to explain BDry's procedure was very courteous and professional. I received a quote on the spot. I had two other companies come out (one company did not even bother to get back to me with an estimate). Each company had a different opinion of what needed to be done and BDry's procedure was the least invasive and made the most sense. The team who actually did the work was very courteous and stayed until the job was done - a 12 hour process. (That was one question I didn't think to ask - approximately how long would it take) They communicated with us throughout the day, for example they asked where we wanted the sump pump to drain, instead of just making the decision. Overall, I am very happy we chose BDry.!"

"I subcontracted Dort Dreams for a driveway lane addition and a big patio in the back. He made last minute alterations without any problem to appease my customer on the thickness of the new slab for the patio. Both the driveway and the patio look great."

"Overall, it was a good experience. AAA put down a vapor barrier and installed a Santa Fe dehumidifier with sump pump. The result is that we can now use the stand-up basement/crawlspace to store things under the house without ruining them. This is the part that you need to know. The installation was not without problems. First, they broke an A/C drain pipe, second, they cut a sprinkler controller wire while running a PVC pipe. Here's my take, accidents happen but how does the business respond to these issues? Well, Donna was very quick to send her team out to correct the problems and they even paid for the damage to the sprinkler system. To me, that's top notch customer service. Any business can make a mistake, but how they handle it is the mark of a good company. Every time I lift the roll door and go into the basement now, I'm amazed at how cool and fresh the air is down there. No more mildew and no more smell."

"I interviewed four companies to understand who had the most experience. It was clear that Raisecrete has the most slab and foundation experience of the four companies. Their price was in line with the other three, but I was most interested in their experience. They communicated constantly prior to doing the job to make sure we had everything lined up. They were punctual and took the time to explain the process and discuss the best method of repairs. The outcome was exactly as they said it would be and I feel I have a permanent fix to the crack in my slab. He has a large crew that all worked hard the entire time. In addition, they checked out my entire foundation to make sure everything checked out. I highly recommend them and would use them again."

Foundation Drain Installation FAQs, answered by experts

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

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.
