Right Stone Masonry takes pride in helping residential, commercial, and industrial property owners maintain safety, preserve character, and repair masonry structures, whether You want to keep Your building in great condition or achieve a new vision entirely.

"James and his team were quick, punctual, and James was incredibly responsive, always responding to calls or texts within minutes. Proposed a sound engineering solution to a challenging problem, where other contractors I spoke to offered expensive decorative solutions that would not have addressed the problem. The finished work is also beautiful, and adds to the appeal of our back yard. I would hire him and his team again."

Basement waterproofing services FAQs

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.
