"Just had ours put in, and it looks great. Our installation team ( Lenny, Terrence, and Manny ) were on time, friendly, hard working and meticulous. Lenny took time to explain things when I popped down and was very patient with questions while working incredibly hard. We have friends who literally live in a swamp who had Busy Dog a couple years ago and their system has worked perfectly. They were getting water in their basement several times a year-- now NOTHING. And I love the technology innovations by this company, the quality of the materials is top notch. Salesman Mike worked with us to set up the construction, he and their engineer came out several times to make sure they understood our tricky set up and worked to get the timing right for timing that worked for us"

"The system was installed so that the pipes were pitched away from the sump, the pipe from the sump outside leaked back into the basement, and the exterior drain wasnt dug to grade so water backed up towards the house. When contacted about the issue, dryzone sent out a tech who confirmed every issue. The company then refused to fix anything without a second opinion. A month after I filed a chargeback, the GM called to "apologize", and made it sound like he wouldnt contest the chargeback, but offered no remedy to the situation. He then contested the chargeback and lied on the chargeback rebuttal. Eventually they settled for a partial refund. Terrible company, dont recommend."

"Thomas and Angelo (his crewman) were fantastic. (He had more crew, but Angelo was the only one whose name I knew.) They correctly diagnosed the problem (foundation cracks), sealed everything, installed a new sump pump and redid the flooring. They kept me informed every step of the way and started work within a day or two of hiring. The basement has remained dry as a bone ever since. One thing to note: They do require payment quickly (not all upfront but soon) and do not take credit cards."

FAQs for basement waterproofing projects in Westport, MA

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

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.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
