How To Choose a Foundation Repair Company

You need a good foundation repair contractor to accurately evaluate issues and make appropriate repairs. Do your research and focus on these key factors when selecting the right company.

Experience

Find a local foundation repair company with extensive experience fixing all kinds of foundation problems. It should have specialized knowledge of the latest repair techniques and materials. Ask how long a company has served your area.

Reputation

Reading through online reviews, checking the Better Business Bureau, and requesting local references helps you confirm that a provider consistently delivers good workmanship and a great customer experience. Pay attention if you see numerous complaints about shoddy repairs or poor service.

Licensing and Insurance

Choose a provider that has the right licenses, bonds, and coverage plans for liability and workers' compensation. There are no state-level licensing requirements for general contractors in Pennsylvania; however, home improvement contractors need to register with the Attorney General's Office. You should check with your city or county government to find out if there are local contractor licensing requirements. There may be additional requirements for contractors to do certain concrete work.

Warranties

Choose a company that offers transferable warranties of at least a decade, ideally up to lifetime guarantees, to fully back their foundation repairs. This demonstrates that they stand behind the quality of their repairs and offers protection in case of future issues.

Questions To Ask Foundation Repair Companies

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

  • Realistically, how long will repairs take to complete? Look for companies that provide reasonable estimates.
  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.
  • What exact repair method do you recommend for this specific situation and why? Your provider may offer options such as steel piers, wall anchors, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • 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 unneeded work.
  • What guarantees do you offer? Reliable companies typically provide labor and materials warranties of at least 10 years.
  • Can you provide a complete written cost estimate and project scope? Asking for a quote in writing helps protect you from unexpected costs.

Carefully assessing foundation repair companies helps homeowners locate the best fit for their needs. A company that can answer the above questions likely delivers long-lasting, quality repairs. Repairing foundation problems right away lowers the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Philadelphia, PA

There are a variety of signs that your foundation needs repairs. These might 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, Philadelphia homeowners spend roughly $3,608 on foundation repair. The amount you'll spend on 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 play a part. The fastest way to find out how much a job might cost is to reach out to 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 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 piering or leveling, is the process of leveling your foundation by underpinning it with large concrete piers. The price will be based 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, and the total cost will depend on what material is used and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs that help prevent water from getting into your foundation. This can involve 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 constructing a new house, make sure that a soil report is completed. This report contains information regarding how well your soil can support a foundation, and can offer you a heads-up about potential future issues. If your concerns are about an existing house, a few hundred dollars will cover 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 at an appropriate level. As Philadelphia sees more rain than many other places, keep an eye on your gutters and landscaping to make sure too much water isn't getting into your soil or foundation. Also, be on the lookout for leaky gutters or pipes, so you can get them repaired quickly.

Foundation repair usually requires a permit, but getting one isn't your responsibility. Your foundation repair provider should obtain the permit and all other documents required in Philadelphia, and should be able to explain the process and/or provide the documents before starting work.

It's smart to talk to your foundation repair company about your concerns before beginning any project. Most of the time, yes, you and your family will be able to remain in your home while foundation work is being done.

The length of time foundation repairs will take varies greatly based on the kind of repair that is needed and the size of your house. Most repairs will take anywhere from one to several weeks. Talk to your Philadelphia foundation repair professional for a more specific timeline for your project.
