"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"They did the job as defined in the scope. I have not been able to test its full function until we have a heavy rain storm . It is designed to keep the basement dry under heavy rain or tropical down pours.. I was very pleased that they were on time and very communicative throughout the engagement."

"When I first called, I was surprised at how quickly they returned my phone call to set up an estimate. He was able to come over the next evening to check out our basement. He was punctual and provided us information about what would need to be done. He stated that he would provide us with an estimate that evening. I waited, but the estimate never came. I called the following week to see the status of the estimate. They stated that they were busy, but I should have it by now and would email it ASAP. After a second week, I called again. They said they would get it to me again. After the third week, I called again and was told the same thing. I gave up at that point and contacted someone else, who will be fixing the basement tomorrow. It's been over a month now and never received an estimate for the work. I understand that it's a busy time of year, but was disappointed to never get the estimate and didn't feel like I should have to pester them for it.

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

Basement Waterproofing FAQs, answered by experts

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits
