"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!

"Don't be pressured into having the work done on their schedule. I had way too much "stuff: in my basement, that is now pushed to the center of the basement and even though is was covered with plastic, everything is covered with white dust. As far as the finished drainage work, I'm very pleased."

Basement Waterproofing questions, answered by experts

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
