"I was very pleased with Smith Waterproofing. Tom and Kristina did the work themselves. They were here when they said they would be. They explained what they would have to do to fix the problem and then they did it. They kept everything clean and neat. I appreciate the job they did."

"A superior company. They follow through on their commitments. They have long time employees with great experience. BWN waterproofed our leaky basement about 10 years ago. No problems for almost a decade. After a recent weekend downpour we had water along one of the basement western storm-facing walls. We called and opened a service ticket with Gary. They called back in a little over a day and scheduled a repair at our convenience. Joe, a long time employee, very courteous, professional, and respectful, arrived on the job. He had reviewed our prior project and knew the property well. And it was a window well drain that had clogged. Luckily, it was easily unclogged and the problem was completely solved. We have always been pleased with the work and response of this locally owned business."

"I had a previous company come in to waterproof my basement and they charged me more than Once and Done and did a horrendous job. They didn't do it correctly and more mold grew. Once and down came in, tore out the previous work and put in their system and my basement is completely dry even during the wettest months & completely mold-free. They gave excellent customer service and priced the job VERY reasonably. This is an honest company and do super work. I would give them 10 stars if I could."

"This team was great. Tim did the initial site visit and explained everything in detail while drawing a diagram of the work to be completed. Crew was on time, friendly, professional and started work right away. Only about one third of basement needed waterproofing. If future conditions require additional areas to be waterproofed, I will definitely call Highlander."

"This is the second time we have hired Groundworks (formerly Bakers Waterproofing) to perform work at our house. The first project was in 2017 when we had the waterproofing system installed. We called Groundworks a few weeks ago to get an estimate on lifting our front sidewalk and stairs that have sunk a lot over the past year. The steps had sunk to the point that the railings were not connected to the house, making it very unsafe for anyone coming into the front of our home. Aaron Lenker & Corbin Gillichbover were very professional and knowledgeable when they arrived to assess our sidewalk and steps to lift them. They left our sidewalk and the surrounding area better than when they arrived. Our steps and sidewalk are now level, and the railings are securely attached to the house again. We are thrilled! I would highly recommend Groundworks if you need a basement waterproofing system or any concrete lifted."

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.
