How To Choose a Foundation Repair Company

Working with a qualified foundation repair company is important for accurately evaluating the damage and completing repairs correctly. We suggest focusing on these main factors.

Experience

Choose a well-established local company with extensive experience successfully handling all types 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

Thoroughly reading online reviews, checking the Better Business Bureau, and getting local references helps confirm that a company consistently delivers top-notch workmanship and great service. Pay attention to any complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both liability and workers compensation insurance. There is no state-level licensing in Illinois; you'll need to check with your city or municipal government to learn about any local requirements. You can determine if a company's business registration is in good standing on the Secretary of State's website. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Opt for a provider offering long transferable warranties of at least 10 years, ideally lifetime guarantees, to completely back its repair work. This exhibits confidence that the repairs will be effective and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

To compare foundation repair providers, you should ask specific questions such as:

  • What warranties do you provide? Reputable providers typically provide labor and materials warranties for at least 10 years.
  • What repairs do you recommend for my situation, and why? Your contractor may consider options such as carbon fiber, wall anchors, and steel piers. Asking allows you to compare suggested solutions between companies.
  • Can you provide a project scope and cost estimate in writing? Make sure to get quotes in writing to shield yourself from unexpected expenses.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • What foundation flaws did you identify during inspection that could be causing the issue? The response should have easy-to-understand explanations and solutions. If a provider offers an unclear answer, it may be trying to bill you for extra work.

Thoroughly assessing foundation repair companies helps homeowners identify the ideal match for their needs. A provider that can answer the questions above is likely one that delivers high-quality, durable repairs. Swiftly tackling foundation problems helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in Alton, IL

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

On average, Alton homeowners spend roughly $1,901 on foundation repair. The total cost of foundation repair will vary greatly depending on several factors. Things like the size of your home, the type of repair needed, and the extent of the damage will all factor in. The easiest way to find out how much a job might cost is to contact a local foundation repair company and schedule a free inspection and estimate.

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

Crack repair and leak repair are exactly as they sound: your foundation repair expert will perform an inspection and take necessary measures to remedy cracks or leaks. The price will vary based on the size and cause of the issue.

Underpinning, also called leveling or piering, is the process of leveling your foundation by underpinning it with large concrete piers. The amount you can expect to spend depends on how many piers are needed. The price of stabilization is also variable. This process reinforces bowing walls with steel or carbon fiber strips, and the total cost will depend on the material and how many strips are used.

Finally, waterproofing is an overarching term for a number of jobs designed to stop water from getting into your foundation or basement. This can include interior waterproofing, exterior waterproofing, or both, and the price can vary greatly. We recommend contacting a waterproofing specialist if you think your foundation needs waterproofing.

If you're building a new home, have a soil report completed. This report contains information about how well the soil on a given piece of land can support a foundation, and can give you a heads-up about potential future problems. If you have concerns 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 current problems that need attention, and advise you on avoiding future problems.

You also want to make sure that the moisture around your foundation is appropriate. Don't let the soil around your Alton home get too dry or too wet; at different times, you might find yourself having to reroute your gutters or water your foundation. Also, be on the lookout for leaky gutters or pipes and repair them quickly.

Your foundation repair provider should be the one obtaining the permits. You can ask the company to provide a detailed explanation of its process and to see the paperwork and permits it has acquired to make sure everything is properly authorized per Alton regulations.

You should talk to your foundation repair company about your concerns before you commit to any project. Most of the time, yes, you should be able to remain in your home while foundation repairs are underway.

Foundation repair, especially very involved repairs like basement waterproofing, should last a long time. This is particularly true when you employ a reliable company. By solving systemic issues with your foundation, or reinforcing important areas, you reduce your risk of future problems.
