How To Choose a Foundation Repair Company

You need a good foundation repair contractor to properly assess issues and make appropriate repairs. Do your research and focus on these key factors when looking for the right company.

Experience

Choose a well-established local provider with many years, ideally decades, of experience successfully completing all kinds of foundation repairs. These companies have specialized expertise with the latest methods and materials. Ask how long a company has served homes in your area.

Reputation

Reading through online reviews, checking the Better Business Bureau, and asking for local references helps you verify that a provider consistently delivers quality work and a great customer experience. Pay attention if you see numerous complaints about poor service or faulty repairs.

Licensing and Insurance

It's important to select a company that has the correct licenses, bonding, and coverage for liability and workers' compensation. General contractors in Colorado don't need a state license, but your local government may have its own requirements. To verify whether a contractor has a valid business license, you can check on the Secretary of State's website. There may be additional requirements for contractors to do certain concrete work.

Warranties

Choose a company that offers transferable warranties of at least 10 years, ideally up to lifetime guarantees, to fully back their foundation repairs. This demonstrates confidence in the quality of their work and offers protection in case of future issues.

Questions To Ask Foundation Repair Companies

To compare foundation repair companies, you should ask detailed questions such as:

  • What type of guarantees do you offer? Reputable companies will offer warranties of at least 10 years on materials and labor.
  • What are some likely causes of the problem based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be attempting to bill you for extra work.
  • What exact repair method do you recommend for this specific situation and why? Your provider may offer options such as wall anchors, steel piers, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to shield yourself from unexpected costs.
  • How long will repairs realistically take? Look for providers that provide reasonable estimates.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.

Taking time to carefully evaluate foundation repair contractors will help homeowners discover the right company for their needs. A company that can thoroughly answer these questions is likely one that delivers durable, high-quality repairs. Swiftly addressing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Boulder, CO

If your foundation is in need of repair, it may manifest in a number of ways. Outside, you might see a crumbling or cracking foundation or a cracked driveway. Your ground level might have uneven or cracked floors. You may notice windows and doors that are sticking in their frames, or that the frames are skewed. You may also notice cracking, buckling, or bowing walls.

On average, Boulder homeowners spend about $2,830 on foundation repair. The total cost of foundation repair will vary greatly depending on several factors. Things like the extent of the damage, the size of your home, and the type of repair needed will all help determine the cost. The easiest way to find out how much a job could cost is to talk to a local foundation repair company and schedule a free inspection and estimate.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

Leak repair and crack repair involve a technician coming to your home, performing an inspection, and using various measures to fix leaks or cracks. The cost of these procedures can vary greatly depending on the size and root cause of the issue.

Stabilization is the process of fixing bowing walls by inserting carbon fiber or steel strips. The amount you spend will depend on the material used and the number of strips required. The cost of underpinning also varies. This process, sometimes referred to as leveling or piering, involves underpinning your foundation with concrete piers to level it; the cost depends on how many piers are used.

If you're looking to waterproof your foundation or basement, we recommend speaking with a waterproofing specialist. This process might include indoor waterproofing, outdoor waterproofing, or both.

To protect your foundation, you should make sure that it gets the proper level of moisture. Boulder tends to be a very dry place, so in times of little rain you may need to water your foundation. Also be sure to quickly identify and repair any leaking gutters or pipes.

If you think there may be any problems with your foundation, you can contact a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can provide you with a list of things to be aware of as well as more ideas to help you further protect your foundation. Lastly, if you're constructing a new house, make sure that you have a soil report done. This can provide information about how well the soil on your property will be able to support a foundation, and can highlight any potential future problems.

Permits are needed for most foundation repairs, but obtaining one won't be your responsibility. Your foundation repair professional should put together all the permits and other documents required in Boulder, and should be able to provide the documents and/or explain the process if asked.

If your foundation needs of waterproofing, you might notice signs like hairline cracks, basement flooding, discoloration or odors, white powder or spots on your walls, uneven floors, or signs of mildew, fungus, or mold.

You can opt for interior or exterior waterproofing. Interior waterproofing typically is less expensive, and involves solutions like the use of sealants or the installation of sump pumps or drains. Exterior waterproofing is more expensive but more effective. Exterior waterproofing can involve things like landscaping changes, external drains, or physical barriers to keep water out of basements and crawl spaces.

Foundation repairs can sometimes, foundation repairs can be considered capital improvements if they fit the criteria of an improvement that adds to your house's overall value, prolongs its life, or adapts it to new uses. Making capital improvements sometimes helps you qualify for tax breaks. (Talk to your Colorado tax professional to learn more.) Even if you don't qualify for tax breaks, foundation repairs will, in most cases, positively affect the value of your home.
