Common Causes of Foundation Problems in Knoxville

Foundation issues have a few possible causes. Here are the most prevalent ones for Knoxville residents:

  • Improper modifications: Landscaping or roofing work that wasn't completed to standard could result in your foundation settling.
  • Standing water: Water accumulation around your home can be menacing to your foundation's integrity, especially when it collects in areas your gutters don't protect.
  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Knoxville receives, the soil soaks up moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction presses against nearby foundations, even if the foundations stay dry.
  • Aging plumbing: Knoxville has its fair share of older homes, with a median building year of 1951. Many of these properties use cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can enter a home's foundation through crevices, and may apply force that results in your foundation fracturing, pipes being damaged, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

When choosing a foundation contractor, you should consider your personal priorities. Ask each provider on your list about the following qualities.

Licensing and Experience

In Tennessee, foundation work has its own residential building contractor license classification. Any company that performs foundation work valued at over $25,000 must have a license, no matter whether it is a primary contractor or subcontractor. You can also get a sense of a company's experience through what its representatives say. Inquire about its inspection processes, local code requirements, permit-pulling procedures, and fees.

Another way to evaluate a company's reputation is to look at 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 committing to a company, check its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. Remember that complaints don't necessarily mean a contractor is incompetent. BBB reviews also show how companies address complaints. A responsive team that aims to achieve positive outcomes is a good one. Avoid a company if you don't see clear communication about problems.

Foundation Repair Cost in Knoxville

The price of foundation repair can differ quite significantly depending on the degree of the issues and what's necessary to resolve them. For minor foundation cracking and settling concerns, you may pay as little as $1,800. However, if there is substantial damage, the average cost lands at about $2,900. More intricate projects involving tunneling, helical piers, or major mudjacking could cost upwards of $6,900. This table shows the average foundation repair costs for common issues.
