Common Causes of Foundation Problems in Renton

Some frequent reasons why Renton homeowners face foundation issues include:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Renton receives, the soil soaks up moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction puts pressure on nearby foundations, even if the foundations stay dry.
  • Improper modifications: Roofing or landscaping work that wasn't done properly could result in your foundation settling.
  • Standing water: Standing water around your home can threaten your foundation's integrity, especially when it gathers in areas your drainage system doesn't cover.
  • Tree Roots: Tree roots can enter a home's foundation through crevices, and may exert pressure that causes your foundation cracking, pipes leaking, and overall structural weakening.

How to Choose the Best Foundation Repair Company

Your home's stability relies on its foundation. It's vital to hire the top professionals possible. Center your research on these characteristics:

Licensing and Experience

Washington foundation repair companies can be either general or specialty contractors. Look for companies with a concrete certification, showing that they follow best practices in the foundation field. You can also get a sense of a company's experience through the details its representatives share. Inquire about its inspection methods, local codes, permit-pulling procedures, and fees. Another way to determine a company's credibility is to check its website. There, you can learn how long it's been in business and its trade accreditations. It might also share knowledge and insights through blog posts, podcasts, or videos.

Customer Reviews

Before choosing a company, examine its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. Complaints don't mean a contractor is unreliable. BBB reviews show how the company dealt with complaints. It's a positive sign if the company has settled issues proactively and favorably. You should avoid a company with many negative reviews, no credentials, and no communication regarding issues.

Foundation Repair Cost in Renton

The price of foundation repair can range widely depending on the extent of the issues and what's required to resolve them. For minor foundation cracking and settling issues, you may pay as little as $1,800. However, if there is significant deterioration, the typical cost lands at about $3,000. More complex projects involving tunneling, helical piers, or major mudjacking could cost upwards of $6,900.

Below are the average foundation repair costs for common issues.

Common Foundation Repair ServicesAverage Cost
Crack Repair$358
Leak Repair$2,890
