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 conduct research beforehand, focusing on the factors listed here.

Experience

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

Reputation

Looking through online reviews, checking the Better Business Bureau, and requesting local references helps verify that a company consistently provides quality work and great customer service. Pay attention if you see numerous complaints about faulty repairs or poor service.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both liability and workers compensation insurance. Pennsylvania does not require general contractors to hold state-level licensure; however, home improvement contractors must register with the Attorney General's Office. You should check with your county or city government to find out if there are local licensing requirements for contractors. There may be additional requirements for contractors to do certain concrete work.

Warranties

Choose a provider that offers long 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

When examining potential foundation repair companies, make sure to ask precise questions such as:

  • Can you provide a cost estimate and project scope in writing? Be sure to get quotes in writing to shield yourself from unexpected costs.
  • What are some likely causes of the problem 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? Providers often offer payment plans for larger foundation repairs.
  • 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.
  • Realistically, how long will the repairs take to complete? Look for companies that provide reasonable estimates.
  • What guarantees do you provide? Reliable companies typically provide labor and materials warranties for at least 10 years.

Taking time to vet foundation repair companies will help you select the right one for you. Providers that can thoroughly answer these questions will likely offer long-lasting, high-quality repairs. Promptly addressing foundation issues helps prevent future structural damage.

Frequently Asked Questions About Foundation Repair in King of Prussia, PA

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

On average, King of Prussia homeowners spend roughly $3,609 on foundation repair. The amount you'll spend on foundation repair is based 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 easiest way to determine how much a job might cost is to talk to 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 exactly as they sound: your foundation repair expert will perform an inspection and take necessary measures to remedy cracks or leaks. Costs will depend on the size and cause of the problem.

Underpinning, also called leveling or piering, is when a contractor levels your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are needed. The price of stabilization varies similarly. This process involves fixing bowing walls by reinforcing them with steel or carbon fiber strips, and the cost will depend on what material is used and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs intended to 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 constructing a new home, have a soil report completed. A soil report will contain information about how well the soil on a given piece of land can support a foundation, and can provide you with a heads-up about potential future issues. If your concerns are about an existing home, for a few hundred dollars, you can get an inspection and report by a structural engineer. The engineer can point you to any issues that need attention, and give you advice on avoiding future problems.

It's also important that the moisture around your foundation is appropriate. As King of Prussia 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 pipes or gutters, so you can get them repaired quickly.

Your foundation repair provider should be the one to get 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 verify that everything is properly authorized per King of Prussia regulations.

You should talk to your foundation repair technician about this before beginning any project. Most of the time, yes, you should be able to remain at home while foundation repairs are underway.

You may not want to spend money hiring someone for what appears to be a small foundation repair. However, it's always a smart idea to consult a professional. This helps you avoid more expensive issues down the road. You may be able to fix small hairline cracks yourself, but it's always a smart idea to get an expert opinion first.
