"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

FAQs for basement waterproofing projects in Plainsboro, NJ

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.
