"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Foundation Repair questions, answered by experts

You may want to hire a concrete floor contractor to check out your home’s concrete surfaces or inspect your home’s foundation for minor damages that they can fix while on site. They may be able to fix cracks in your driveway or garage floor the same day they fix your concrete steps, as well. General concrete repair experts usually won’t be able to handle larger jobs, like leveling a sunken foundation, so you’ll need to hire a structural engineer for bigger projects.

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

Yes, foundation problems can cause ceilings to collapse or even your whole house to crumble. Left unaddressed, natural sinking can build up and eventually harm your home’s supporting structure, such as walls, beams, and frames. Your basement ceiling may be the first place to look for signs of a ceiling collapse caused by foundation problems.

Periodic sealing and cleaning to maintain appearance and integrity.
