How To Choose a Foundation Repair Company

Working with a qualified foundation repair business is important for accurately evaluating the damage and completing repairs correctly. We recommend focusing on these key factors.

Experience

Find a local foundation repair provider with comprehensive experience fixing all kinds of foundation problems. It should have expertise in the latest repair techniques and materials. Ask how long a provider has served your area.

Reputation

Spend time researching online reviews, browsing the Better Business Bureau, and requesting local references. This will help confirm that a provider consistently delivers good workmanship and professionalism. Take note of complaints mentioning poor service or faulty repairs.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both liability and workers compensation insurance. 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 verify a Maine business license on the Secretary of State's website. There may be additional requirements for contractors to do certain concrete work.

Warranties

Pick a provider that offers long transferable warranties for a minimum of 10 years and, if possible, lifetime guarantees to fully back its foundation repair services. This displays confidence that the company's work is top-notch and provides protection should problems come up later.

Questions To Ask Foundation Repair Companies

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

  • How long will the repairs realistically take to complete? Look for companies that provide reasonable estimates.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps shield you from unexpected costs.
  • What warranties do you provide? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • What repair method do you recommend for this specific situation and why? Your provider may consider options such as steel piers, wall anchors, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • What options do you offer for financing? Many providers offer payment plans for larger foundation projects.
  • What foundation flaws did you identify during inspection that may 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.

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 high-quality, long-lasting repairs. Promptly fixing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Portland, ME

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

On average, Portland homeowners pay roughly $3,067 for foundation repair, although the actual cost will depend on several factors. The best way to get an estimate for the cost of your specific project is to ask for quotes from a few local foundation repair companies. The amount you pay for a job will be influenced by things like the size of your house and type of repair(s) needed.

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 contractor will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will depend 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 price will be based on how many piers are needed. 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 the material and how many strips are used.

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

When caring for your foundation, you should make sure it has the proper level of moisture. Portland 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. Also be sure to promptly identify and repair any leaking pipes or gutters.

If you have any concerns about your foundation, you can call a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can net you a list of things to be aware of as well as additional steps to further protect your foundation. Lastly, if you're building a new house, ensure that you have a soil report done. This can provide information regarding how well the soil on your property can support a foundation, and can highlight potential future issues.

Your foundation repair expert should be the one obtaining the 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 assembled to confirm everything is properly authorized per Portland regulations.

Sometimes, foundation repairs can be considered capital improvements if they meet the criteria of an improvement that will add to a home's overall market value, prolong its life, or adapt it to new uses. In some cases, making capital improvements lets you qualify for tax breaks. (Talk to your Maine tax professional for more information.) Even without these tax breaks, foundation repairs will generally have a positive effect on your home's value.

While some foundation problems might seem small and not worth the cost to repair, when left untreated, they can lead to much larger and more expensive problems in the future. Foundation issues can also have underlying causes which are not clear until after a professional inspection. It's important to fix these underlying issues as soon as possible. For these reasons, we advise against procrastinating on foundation repairs.
