"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."

"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

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

If your foundation is unfinished, has surface damage, or is just plain unappealing, foundation refacing can be another great way to increase your curb appeal and give your foundation a fresh look. Used in conjunction with foundation planting, refacing can completely change the look of your foundation and your home. 

Foundation repairs typically require a building permit, depending on the state and local jurisdiction. Make sure your contractor follows all building codes, and a local building inspector will review all work to ensure that it is up to code. Not following local building codes can prevent the sale of your home and potentially put your home at an even greater risk of damage if the work isn’t done properly. You can call your local municipal office to confirm that your contractor has filed the necessary permits.
