We used Foundation1 to completely rebuild 2 basement walls and push another one back up and support it. They did a great job and done it quickly and professionally. I do not live in the KC area and needed to find a contractor that could be counted on to be honest and stand behind their work....

"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."

"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!
