Here's our story.... Once upon a time (over 10 years ago to be exact and counting) two great guys started in the waterproofing industry. After working our way to the top of some of the biggest and well known waterproofing companies in the industry gaining tons of practical experience we had an epiphany. We realized 2 major things. First we were doing phenomenal work, late nights, tons of back breaking labor with absolutely no recognition and little pay. Second we realized the most important issue in this business is the lack of customer satisfaction. Most of the big time companies only care about the money not how much the customer saves or if they solved their wet basement issue but how much they can put in their bank accounts. We got tired of hearing customers complain about the lack of respect and attention they received from the big companies so We set out to change this by putting YOU the customer first. Strongmen Waterproofing truly cares about helping solve your Wet basement problems with the latest and most efficient methods to date. So if you want the experience of a dry basement with out all the B.S. just results then call us today! We guarantee you will be glad you did!

"Nick and the crew were professional, hardworking and did above and beyond. I can't express how much I appreciate the hard work they did within my basement to redirect the ground water to a new sump pump; it rained out heavy the next two days and my basement was dry, and my new sump pump was working great! I couldn't believe what a great job they did it shows they did not cut any corners and new what they were doing. I highly recommend Supreme Waterproofing to all you friends in need of a dry basement I know I will. Thank you Nick!!!"

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.
