Each year sinking foundations, cracked and buckled walls, and cracked and uneven floors affect millions of families. Buildings situated on unstable soils will settle when the foundation is subjected to moisture or poor drainage. A shifting foundation could result in structural damage and potentially, a loss of your investment. Foundation problems should be addressed as soon as they are discovered before the damage is irreversible. If you notice any of these signs, call us at Seattle Foundation Repair to protect your property value and ensure the safety of your home.

"I contacted them for work and have regretted it ever since. They pull you around and act responsive until the rubber hits the road to take action, ghosting me ever since. They billed me 900 dollars for something they did not do. They promised to bury the concrete they dug up and broke their word. I texted the owner until he stopped responding. I emailed them until they stopped responding—terrible company to work with."

Foundation Repair questions, 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.

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.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.
