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 recommend looking for a local foundation repair provider with a well-established track record of fixing various foundation issues. These companies should have deep knowledge of the latest materials and techniques. Ask how many years a provider has served your area.

Reputation

Thoroughly reading online reviews, checking the Better Business Bureau, and asking for local references helps verify 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

Make sure any company you hire has the appropriate licenses, bonds, and coverage for liability and workers' compensation. There are no state-level licensing requirements for general contractors in Delaware, but your local government may have its own requirements. You can verify a contractor's business license by searching through the Delaware Division of Revenue. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Look for a company that provides lengthy transferable warranties for a minimum of a decade, or preferably lifetime guarantees, to back its foundation repairs. This demonstrates faith that its services are top-quality and safeguards you if issues come up in the future.

Questions To Ask Foundation Repair Companies

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

  • Can you provide a complete written cost estimate and project scope? Getting the details in writing helps protect you from unexpected costs.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.
  • What do you see as the likely cause 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 unneeded work.
  • What repair method do you recommend for this specific situation and why? Your provider may offer options such as carbon fiber, wall anchors, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What guarantees do you provide? Reliable companies typically provide labor and materials warranties that last at least 10 years.
  • What financing options do you have? Many providers offer payment plans for larger foundation projects.

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

Frequently Asked Questions About Foundation Repair in Wilmington, DE

There are a variety of signs that your foundation needs repairs. These can include:

  • Visible crumbling or cracking of your foundation
  • Uneven ground-level floors
  • Buckling, bowing, or cracked walls
  • Door or window frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Wilmington homeowners spend roughly $3,161 on foundation repair. The cost of foundation repair will vary greatly depending on several factors. Things like the type of repair needed, the extent of the damage, and the size of your home will all play a part. The fastest way to determine how much a job might cost is to contact a local foundation repair company and schedule a free inspection and estimate.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

For both leak repair and crack repair, a technician will come to your home, complete an inspection, and use various measures to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and cause of the problem.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The amount you spend will depend on the material chosen and how many strips are required. The cost of underpinning also varies. This process, sometimes referred to as piering or leveling, involves underpinning your foundation with concrete piers to level it; the cost is based on how many piers are needed.

If you're interested in waterproofing your foundation or basement, we recommend looking for a waterproofing specialist. This process can include outdoor waterproofing, indoor waterproofing, or both.

When building a new house, have a soil report completed. A soil report will contain information regarding how well your soil can support a foundation, and can offer you a heads-up about any potential future problems. If you have concerns about an existing house, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can alert you to any things that could use some attention, and advise you on avoiding future problems.

It's also important that the moisture around your foundation is appropriate. Don't let the soil around your Wilmington 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, so you can get them repaired quickly.

Permits are needed for most foundation repairs, but acquiring one should not be your responsibility. Your foundation repair provider should obtain the permit and all other documents required in Wilmington, and should be able to explain the process and/or provide the documents before starting work.

Small hairline cracks might seem easy to take care of on your own, but in general, it's a good idea to consult a professional before beginning any foundation maintenance. Although you may balk at the idea of paying someone for a job you feel like you can handle yourself, mistakes made during foundation repair can be even more costly in the future.

We recommend that you do not put off foundation repairs. A single 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.
