"I recently had the pleasure of working with Stay Dry Waterproofing and I can confidently say that they are the best waterproofing company in town. From start to finish, their team of experts were professional, knowledgeable, and attentive to my needs. The project manager, Brock, was fantastic to work with. He took the time to thoroughly explain the waterproofing process and answered all of my questions with patience and expertise. He also provided a detailed timeline for the project, which helped me plan accordingly. The installation crew arrived on time and worked diligently to complete the project on schedule. They were respectful of my property, kept the work area clean, and were mindful of noise levels. Overall, I was extremely satisfied with the quality of work and level of service provided by Stay Dry Waterproofing. My basement is now completely dry and I have peace of mind knowing that my home is protected from water damage. I highly recommend this company to anyone in need of waterproofing services. They truly deserve 5 stars!"

"I’m so glad we chose Ever Dry to waterproof our basement. The sales rep did a fantastic job at communicating, explaining the process, and had a very competitive price. The workers did a great job and had it done quickly and left no mess behind. I highly recommend them. Ever Dry has a warranty and they fully stand behind their work."

"Stay dry waterproofed my basement and the white plastic they put on my walls to stop the leaks makes my basement look amazing. The bright white makes the space look bigger. I actually can use my basement for storage now."

"We just had Jayson Wright, Service Manager, to our residence to do an inspection of our egress window and a potential water issue on one of the basement walls. Jayson did an excellent job and explained everything that we were concerned about. I fully recommend Jayson Wright and Groundworks for any and all basement issues involving waterproofing."

"They fixed the leak and put in a sump pump and water trench. The basement leaked 2 more times afterwards, but they returned to correct it right away. We were responsible all 3 times to repair the drywall and wood landing at the bottom of the stairs,so I called saying that I should not have to keep fixing those thing over and over. The CEO of the company called back and came out to the house himself to inspect. He had his people come out to the house again to do more that he felt would fix the problem for good, as well fixing the drywall and landing at no cost. It was a frustrating experience, but this company and it's CEO stood by thier work and made it right. I would use them again."

"We had a water issue in our basement, and when we called, one of the owners of Concrete Pro discovered it was from our HVAC condensation line. They explained the issue ( call the HVAC guy). So impressed with the honesty and would refer to anyone"

"Perfect. The technician, Jake, was very knowledgeable and professional. Plumbing was replaced from the outside of the house to the shutoff valve in the basement. Excellent job. I would definitely hire again for any of my plumbing needs."

Basement Waterproofing questions, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
