How To Choose a Foundation Repair Company

Hiring a qualified foundation repair contractor ensures you have someone who will inspect the damage thoroughly and make appropriate fixes. It's important to do your research beforehand, focusing on the factors listed here.

Experience

We suggest looking for a local foundation repair company with a proven reputation for fixing various kinds of foundation problems. These companies should have deep knowledge of the latest materials and techniques. Ask providers how long they've served your area.

Reputation

Researching online reviews, checking the Better Business Bureau, and asking for local references helps you confirm that a provider consistently delivers quality work and a positive customer service experience. Pay attention if you see numerous complaints about shoddy repairs or poor service.

Licensing and Insurance

Only hire companies that are properly licensed, bonded, and have both liability and workers compensation insurance. In Maine, general contracting requirements are set by your city, county, or municipal government, and you'll need to check with a representative at this level 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. There may be additional requirements for contractors 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

While researching options for foundation repair providers, get detailed answers to questions such as:

  • What repairs would you recommend for my situation, and why? Your contractor may consider options such as carbon fiber, steel piers, and wall anchors. Asking allows you to compare suggested solutions between companies.
  • Can you provide a project scope and cost estimate in writing? Be sure to get quotes in writing to protect yourself from unexpected expenses.
  • 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 extra work.
  • How long will the repairs realistically take? Look for providers that provide reasonable estimates.
  • What financing options do you offer? Providers often offer payment plans for larger foundation repairs.
  • What type of warranties do you offer? Trustworthy providers typically offer warranties of at least 10 years on materials and labor.

Carefully reviewing foundation repair companies will help you identify the right one for you. Providers that can thoroughly answer these questions will likely offer durable, high-quality repairs. Promptly addressing foundation issues helps avoid future structural damage.

Frequently Asked Questions About Foundation Repair in South Portland, ME

There are a number of signs that your foundation is in need of repair. These can include:

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

On average, South Portland homeowners pay roughly $3,067 for foundation repair, although the cost will vary widely depending on several factors. The fastest way to estimate the cost of your specific job is to get quotes from a handful of local foundation repair companies. The total price will be determined by things like the size of your house and type of repair(s) needed.

The primary 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 take necessary measures to remedy cracks or leaks. The price will depend on the size and cause of the problem.

Underpinning, also called leveling or piering, is the process of leveling 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 cost will depend on the material chosen and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs intended to stop water from getting into your foundation or basement. This can include exterior waterproofing, interior waterproofing, or both, and costs can vary widely. We recommend contacting a waterproofing specialist if you think your foundation needs waterproofing.

One way to protect your foundation is to make sure that it has the right amount of moisture. South 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. Additionally, make sure that you promptly identify and repair any leaking gutters or pipes.

If you have any concerns about your foundation, you can contact a structural engineer for an evaluation. This will cost a few hundred dollars, but the consultation can provide you with a list of things to be aware of as well as more ideas to help you further protect your foundation. Finally, if you're constructing a new house, make sure that you have a soil report done. This report provides information regarding how well the soil on your property will be able to support a foundation and highlights potential future problems.

Your foundation repair provider 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 acquired to make sure everything is properly authorized per South Portland regulations.

You should ask your foundation repair professional about this issue before committing to any project. Typically, yes, you and your family will be able to remain at home while foundation repairs are underway.

Generally, foundation repairs will have a positive effect on your home's value. In some cases, you may be able to consider foundation repair a capital improvement, which might 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. Speak with your Maine tax professional for the most accurate information.
