"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."

We employee the highest caliber employees and use the best quality products available. We are fully licensed Home Improvement Contractors in every state we serve with the goal of leading the forefront of innovation in all that we do and setting the standard in this trade. We were the first to: Conduct mold remediation while simultaneously waterproofing. Offer lifetime warranties for our waterproofing services for the life of the structure.

Clean out basement crawlspaces and garages while waterproofing.

"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

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.

Sometimes cracked brick can mean a foundation problem, such as when the crack appears indoors and is vertical, or long horizontal cracks either inside or outside. If the crack widens at the top, then it’s safe to assume there is structural damage. Other things to look for are uneven floors, diagonal cracks indoors, and doors and windows that stick.

No, foundation repair is not usually covered by home insurance. Most home insurance companies typically consider foundation repair as part of your home maintenance, so they won’t cover the cost. However, foundation damage is sometimes caused by covered events such as a burst pipe or a house fire. In these cases, repairs may be covered.

Yes, you can fix a block foundation. It’s important to address the issue immediately and have a foundation repair professional understand the severity of the issue and determine the best course of action. If the wall collapses before the foundation is repaired, then you’ll have to reassess your entire foundation.
