"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."

"Dean provided my complimentary basement inspection which consisted of looking for water entry points, foundation and floor cracks, and all potential other water challenges in the basement. He spent about 20 minutes walking me through each point of the Inspection and explaining to me the purpose what he was looking for and why. At the end of the complimentary inspection, Dean confirmed no further action would be necessary. Dean was professional, knowledgeable and polite; never pushy and very honest. I would highly recommend Thompson's Basement Waterproofing's free inspection to anyone concerned about your basement. Thompson's obviously is only interested in selling their products to people who need them; not taking advantage of Homeowner's who don't have the subject matter expertise needed to properly assess this type of situation. Thanks Thompson's!

Basement Waterproofing questions, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

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

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
