"I highly recommend this contractor. They were highly professional in every way: they always came just when they said they would, they did exactly what they said they would, they were great at solving problems that arose during the basement waterproofing project, and they did a really good job of keeping us informed multiple times a day about the progress of the project. The crew that handled our project was outstanding. We were especially appreciative of the work done by the foreman, Dan. Just great all around work."

"Josh Taft and Brad were very personable, professional and efficient. They were also respectful of my house. This is the second time I’ve used your company. No offense, but I hope I don’t need the services of your company again."

"I called numerous companies to give me an estimate on waterproofing our basement. Brandon was quick to respond and was able to address the problem and find a solution that was directed at the specific issue. Highlander was easy to work with and actually enjoyed having the entire crew at the house. They went above and beyond answering any questions with a guarantee and cost that I could live with. I highly recommend Highlander to anyone looking to fix a damp basement."

Basement Waterproofing FAQs, answered by experts

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

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.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
