How To Choose a Foundation Repair Company

Do thorough research before beginning your foundation repair project, so you can find the most qualified foundation repair provider. Here are the main factors to consider.

Experience

Look for a reliable local foundation company with many years of successfully fixing foundations. Technicians should have up-to-date knowledge of current repair materials and methods. Contact the company to ask how long it’s served your community.

Reputation

Reading online reviews, checking the Better Business Bureau, and asking for local references helps confirm that a company regularly provides good workmanship and good service. Pay attention if you see many complaints about faulty repairs or poor service.

Licensing and Insurance

Make sure any company you hire has the appropriate credentials, bonds, 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 work with concrete.

Warranties

Opt for a provider offering transferable coverage for 10+ years, ideally lifetime guarantees, to completely back its repair work. This exhibits belief in the quality and durability of the repairs and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

As you evaluate potential foundation repair companies, make sure to ask in-depth questions such as:

  • Can you provide a complete written project scope and cost estimate? Asking for a quote in writing helps shield you from unexpected expenses.
  • What repairs would you recommend for this situation, and why? Your contractor may offer options such as carbon fiber, steel piers, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be trying to bill you for unneeded work.
  • How long will the repairs realistically take to complete? Look for companies that provide reasonable estimates.
  • What type of guarantees are provided? Trustworthy providers often offer warranties of at least 10 years on materials and labor.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.

Taking time to carefully evaluate foundation repair contractors will help homeowners find the right company for their needs. A company that can thoroughly answer these questions is likely one that offers durable, high-quality repairs. Promptly fixing foundation issues helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Thornton, CO

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

On average, Thornton homeowners pay roughly $2,830 for foundation repair, although the cost will change based on several factors. The best way to estimate the cost of a specific job is to solicit quotes from a few local foundation repair companies. Your total cost will be determined by things like the type of the repair(s) and the size of your house.

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

For both leak repair and crack repair, a technician will come to your home, complete an inspection, and use various repair techniques to fix leaks or cracks. The amount you spend will vary greatly depending on the size and root cause of the issue.

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

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

When building a new house, have a soil report completed. A soil report will contain information regarding how well your soil can support a foundation, and can offer you a heads-up about any potential future problems. If you have concerns about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any issues that could use some attention, and give you advice on avoiding future problems.

You also want to make sure that the moisture around your foundation is at an appropriate level. The weather in Thornton tends to be very dry, which means that at times you may need to water your soil and foundation. Also, be on the lookout for leaky pipes or gutters and repair them quickly.

A permit is normally required for foundation repair, but getting one should not be your responsibility. Your foundation repair professional should put together the permit and all other documents required in Thornton, and should be able to explain the process and/or provide the documents before starting work.

Generally, foundation repairs will positively affect your home's value. In some cases, you may be able to consider foundation repair a capital improvement, which can sometimes allow you to qualify for tax breaks. Generally, a capital improvement is defined as one that adds to your house's overall market value, prolongs its life, or adapts it to new uses. Contact your Colorado tax professional for the most accurate information.

We strongly suggest talking with your home insurance provider before you begin any foundation repairs to figure out what may be covered. Typically, foundation repairs aren't covered by home insurance unless they're to fix damage that was caused by a covered weather event.
