"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

Underpinning is a type of foundation repair in which a repair specialist installs piers under your foundation to provide additional support for the concrete and structure above. Foundation repair is an umbrella term that includes many other repair methods, including foundation crack repair, waterproofing, cosmetic repair, concrete block wall stabilization, and more.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.
