How To Choose a Foundation Repair Company

Conduct research before beginning your foundation repair project in order to find the most qualified foundation repair provider. Here are the main factors to consider.

Experience

We suggest looking for a local foundation repair provider with a long history of fixing various foundation issues. These companies should have expertise in the latest materials and techniques. Ask providers how long they've served your area.

Reputation

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

Licensing and Insurance

Make sure any company you hire has the appropriate licenses, bonds, and coverage for liability and workers' compensation. In Maine, general contracting requirements are determined at the county, city, or municipality level, and you'll need to check with your local government to learn about the requirements in your area. You can confirm that a company has a valid Maine business license on the Secretary of State's website. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Pick a company that offers long transferable warranties for a minimum of 10 years and, if possible, lifetime guarantees to fully back its work. This displays faith that their repairs will be high-quality and long-lasting and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

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

  • Realistically, how long will the repairs take? Look for providers that provide reasonable estimates.
  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be trying to bill you for unnecessary work.
  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • What warranties do you provide? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps shield you from unexpected expenses.
  • What repairs do you recommend for this situation, and why? Your contractor may consider options such as steel piers, carbon fiber, and wall anchors. Asking allows you to compare suggested solutions between companies.

Thoroughly reviewing foundation repair companies helps homeowners identify the best fit for their needs. A company that can answer the above questions likely delivers durable, high-quality repairs. Addressing foundation problems right away reduces the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Windham, ME

There are several signs that your foundation needs repairs. These can include:

  • Visible crumbling or cracks in your foundation
  • Uneven ground-level or basement floors
  • Cracked, bowing, or buckling walls
  • Door or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Windham homeowners spend roughly $3,067 on foundation repair. The total cost of foundation repair is based on several factors. Things like the extent of the damage, the type of repair needed, and the size of your home will all play a part. The easiest way to determine how much a job is going to cost is to speak with a local foundation repair expert and schedule a free inspection and estimate.

The main types of foundation repair are 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 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 when a contractor levels your foundation by underpinning it with large concrete piers. The amount you can expect to spend depends on how many piers are required. The price of stabilization is also variable. This process involves fixing bowing walls by reinforcing them with carbon fiber or steel strips. The cost will depend on the material and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs intended to prevent water from getting into your foundation or basement. 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.

One way to protect your foundation is to make sure it gets the proper level of moisture. Windham sees more rain than many places, so be sure that your gutters and landscaping are arranged to prevent too much water from collecting near your foundation. Additionally, make sure that you quickly identify and fix any leaking gutters or pipes.

If you think there may be any problems with your foundation, you can reach out to a structural engineer for an evaluation. This will cost a few hundred dollars, but the engineer's consultation can net you a list of potential concerns as well as more ideas to help you further protect your foundation. Lastly, if you're constructing a new house, be sure that you have a soil report done. This report provides information regarding how well the soil on your property can support a foundation and highlights potential future problems.

Your foundation repair expert 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 assembled to verify that everything is properly authorized per Windham regulations.

Generally, yes, you'll be able to continue living in your home while foundation repair work is being completed. Talk to your foundation repair technician to know for sure.

You may not love the idea of spending money to hire someone for a seemingly small foundation repair. However, it's always good to consult a professional. This way, you can avoid potential future issues that could be even more expensive. You may be able to repair small hairline cracks yourself, but it's always good to get an expert opinion first.
