This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Causes of Foundation Problems in Danbury

A home in Danbury might experience foundation issues for various reasons. Some are specific to the local environment, while others are prevalent nationwide. They include:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Danbury receives, the soil absorbs moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction puts pressure on nearby foundations, even if the foundations keep dry.
  • Topsoil Frost: When temperatures plummet, topsoil freezes rapidly and lower layers can't expand, pushing upper layers to heave and permanently damage infrastructure.
  • Improper modifications: Roofing or landscaping work that wasn't performed to standard could lead to your foundation settling.
  • Tree Roots: Tree roots can intrude into a home's foundation through crevices, and may create stress that leads to your foundation breaking, pipes leaking, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

Choosing a foundation contractor doesn't have to be challenging. We encourage you to write down what you want most in a contractor, then evaluate each company on your selection against these attributes.

Licensing and Experience

In Connecticut, foundation repair companies need at least a Home Improvement Contractor license from the Department of Consumer Protection for work valued at over $200. Applicants must prove that they have at least $20,000 in liability insurance. Talk to representatives to gain additional insight into a company's experience. You should ask about local permit ordinances, building codes and inspection processes.

Contractor websites are among the best places to do your research. Usually, a foundation company will discuss how long it's been in business. It might also publish other content to assist interested parties.

Customer Reviews

We advise reviewing the company's Better Business Bureau (BBB) profile to determine whether it's accredited and has a high customer review score. You can see whether other homeowners have expressed satisfaction or filed complaints. Pay special attention to what customers say about company warranties. Remember that negative feedback doesn't necessarily mean a contractor is incompetent. BBB comments also show how companies handle complaints. A proactive team that works toward excellent outcomes is a good one. Avoid a company if you don't see clear communication about problems.

Foundation Repair Cost in Danbury

The price of foundation repair can differ quite significantly based on the scale of the issues and what must be fixed. For minor foundation cracking and settling concerns, you may pay as little as $1,800. However, if there is significant deterioration, the average cost falls at about $2,600. More complex projects requiring excavating, helical piers, or major mudjacking could cost $6,800+. See below the average foundation repair costs for common issues.

Common Foundation Repair Services Average Cost
Crack Repair $318
Leak Repair $2,506
Stabilization $4,304
Underpinning $1,222
