"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"Oscar and his crews are top notch! They aggressively pursued my many faceted project through good weather and bad until the whole job was done. Job included demolition, root removal, new brickwork, brickwork repairs, aggregate concrete, fencing, adding a French drain and sump, sprinkler repairs and additions, laying sod, and yes - planting. Rare to find a single contractor that does all this well at a reasonable price."

Foundation Repair FAQs, answered by experts

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.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.

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.
