"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

"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!!"

"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."

Foundation Repair questions, answered by experts

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

In most cases, yes, homeowners insurance will cover burst pipes, even if they run through your foundation. Not only that, but most home insurance companies will also cover any foundation repair you need done that resulted from the plumbing leak because your insurer will view the leak as an unforeseen and non-preventable issue.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

It’s usually not a big deal if your foundation sinks between 2 and 3 inches into the ground after construction, provided the settlement occurs evenly. This is usually indicative of normal settlement that occurs as the soil under your home adapts to the weight of the structure. If the home sinks more into the ground or the settlement occurs unevenly, leaving portions of your home to sink further down than others, then call a foundation repair specialist to address the issue and avoid additional damage.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation.
