Global Basement Waterproofing is family owned and operated and has been in business since the year 2000. We service all of Southern Massachusetts and all of Rhode Island.Our goal is to make your basement Dry and provide continued protection against water intrusion. We install Sump Pumps, French drain systems, Bulk Heads, and Wall Crack Repairs. Most jobs are completed in 1 to 3 days! All of our work is backed up by a Lifetime Transferable Warranty!

"Excellent service. I now feel secure knowing that my sump pump will go on if the power goes off. Unfortunately, I didn’t install the battery backup before the March storms. After Global had done several jobs for me in the past, I thought I was finally going to live without water in my basement but Mother Nature had other ideas. Luckily Bob came to my rescue rather quickly after the flooding. Now I KNOW I’ll be water-free. Bob has never tried to pressure me into buying something I don’t need or can’t afford but I wish I had bought the battery years ago when he first told me about it. I won’t make that mistake again. Cost-wise, Bob will break down the requested work into separate jobs and estimate each so I can make a decision if I can afford all of the work or only some of it. I don't think I've ever worked with a service provider who either answers his phone immediately or calls back promptly. Bob has always kept our appointments, except once when another customer had an emergency. He said he was willing to come over later after hours if I needed him that day. We set up another day for my job, as rescheduling was not a problem for me. I really appreciated that he didn't leave me hanging by not showing up or not calling, like a lot of service providers do. Bob cares about his customers and I’m happy to recommend him and his company."

FAQs for basement waterproofing projects in Harmony, RI

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.
