How To Choose a Foundation Repair Company

Do thorough research before beginning your foundation repair project in order to find the most qualified foundation repair provider. Here are the main factors we recommend considering.

Experience

Look for a reputable local foundation company with a proven history of successfully fixing a wide range of foundation problems. Technicians should have up-to-date knowledge of current repair materials and methods. Contact the company to ask how long the business has served your community.

Reputation

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

Licensing and Insurance

Choose a company that has the right licenses, bonds, and insurance policies for liability and workers' compensation. In Arizona, all contractors must be licensed via the Arizona Registrar of Contractors, unless working on a job that is valued at less than $1,000 and that doesn't require a permit. To be eligible for a license, contractors must have four years of experience, be bonded, and pass an exam. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Opt for a provider offering long transferable warranties of at least 10 years, ideally lifetime guarantees, to completely back its foundation services. This exhibits belief in the quality and durability of the repairs and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

When comparing potential foundation repair companies, be sure to ask detailed questions such as:

  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.
  • How long will repairs realistically take to complete? Look for providers that provide reasonable estimates.
  • What do you see as the likely cause 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 unnecessary work.
  • Can you provide a complete written cost estimate and project scope? Asking for a quote in writing helps shield you from unexpected expenses.
  • What repair method do you recommend for my specific situation and why? Your provider 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 guarantees do you provide? Reliable companies generally provide labor and materials warranties of at least 10 years.

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 offers durable, high-quality repairs. Promptly fixing foundation issues helps avoid further structural damage.

Frequently Asked Questions About Foundation Repair in Flagstaff, AZ

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

On average, Flagstaff homeowners pay around $2,360 for foundation repair, although the total cost will vary depending on several factors. The fastest way to estimate the cost of your specific project is to request 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.

The primary types of foundation repair include crack repair, leak repair, underpinning, stabilization, and waterproofing.

Crack repair and leak repair are what they sound like: your foundation repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will vary depending on the size and cause of the issue.

Underpinning, also called leveling or piering, is when a contractor levels your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are required. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with carbon fiber or steel strips, and the total cost will depend on what material is used and how many strips are used.

Lastly, waterproofing is an overarching term for a category of repairs intended to stop water from getting into your foundation. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary greatly. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

If you're building a new home, have a soil report completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can provide you with a heads-up about any potential future problems. If your concerns are about an existing house, a few hundred dollars will cover an inspection and report by a structural engineer. The engineer can alert you to any things that need attention, and advise you on avoiding future problems.

It's also important that the moisture around your foundation is appropriate. The weather in Flagstaff 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 gutters or pipes and repair them promptly.

Your foundation repair provider should acquire the needed permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to ensure everything is properly authorized per Flagstaff regulations.

In general, foundation repairs will have a positive effect on your home's value. In some cases, foundation repairs may be considered a capital improvement, which might help you qualify for tax breaks. Generally, a capital improvement is defined as one that adds to a home's overall market value, prolongs its life, or adapts it to new uses. Speak with your Arizona tax professional to learn more.

We advise against putting off a foundation repair project. A seemingly small issue may have an underlying cause that could lead to numerous future problems, and it's best to get ahead of the issue as soon as possible. A small and moderately costly problem now could become a large and expensive one in the future if left untreated.
