"Ryan, Sr. Inspector, was professional, courteous, and walked me through my basement, pointing out what needed fixing and exactly what would be done. Came on time and left on time... cleaned up their mess, too! Very fair pricing, definitely worth every penny for a mold-and-moisture free basement! Very highly recommended!"

"Dave with 2 other workers were prompt and efficient. They came when they said they would and finished everything in 2 days. Everything looks fantastic because they protected my personal space with a plastic shield and cleaned everything up. Dirt and rubble was hauled away and they even sprayed my walkways outside. They installed the basement system and connected all my outside downspouts. I would highly recommend Highlander to anyone who needs waterproofing because they went above and beyond to make sure I was happy."

"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."

SaniDry Sedona is the world's most efficient, high-performance dehumidifier and filtration system and is a crucial element in basement waterproofing and crawl space repair. As a result of its compact size, it occupies less space in a basement and can easily be tucked away in a crawl space. The unit eliminates damp, musty odors by drying and filtering the air, and it costs less to run than other dehumidifiers. It filters mold spores, dust mite droppings, dust and other particles, and it keeps hu

"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 FAQs, answered by experts

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

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.

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

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.
