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

We suggest hiring a local foundation repair provider with a proven reputation for fixing various foundation issues. These companies should have expertise in the latest techniques and materials. Ask how many years a provider has served your area.

Reputation

Spend time reading through online reviews, browsing the Better Business Bureau, and asking for local references. This will help verify that a provider consistently delivers good workmanship and professionalism. Take note of any complaints mentioning poor service or faulty repairs.

Licensing and Insurance

Make sure any company you hire has the right licenses, bonds, and coverage for liability and workers' compensation. Pennsylvania does not require general contractors to hold state-level licensure; however, home improvement contractors need to register with the Attorney General's Office. You should check with your city, county, or municipal government to learn whether there are local contractor licensing requirements. 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 foundation services. This exhibits confidence that the repairs will be effective and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

As you evaluate potential foundation repair companies, make sure to ask detailed 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.
  • What foundation defects 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 attempting to bill you for unneeded work.
  • What type of warranties do you offer? Reputable companies typically offer warranties of minimum 10 years on labor and materials.
  • What options do you offer for financing? Providers often offer payment plans for larger foundation repairs.
  • Can you provide a complete written cost estimate and project scope? Getting the details in writing helps shield you from unexpected expenses.
  • Realistically, how long will the repairs take to complete? Look for companies that provide reasonable estimates.

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

Frequently Asked Questions About Foundation Repair in Allentown, PA

There are several signs that your foundation needs repairs. These might include:

  • Visible crumbling or cracking of your foundation
  • Uneven ground-level or basement floors
  • Cracked, bowing, or buckling walls
  • Window or door frames that are skewed or tight
  • Cracks in your basement floor
  • Cracks in your driveway

On average, Allentown homeowners spend around $3,793 on foundation repair. The cost of foundation repair is based on several factors. Things like the extent of the damage, the size of your home, and the type of repair needed will all help determine the cost. The best way to determine how much a job might cost is to contact a local foundation repair expert 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, perform an inspection, and use various repair techniques to remedy leaks or cracks. The cost of these procedures will vary greatly depending on the size and root cause of the problem.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The cost will depend on the material used and the number of strips needed. The cost of underpinning also varies. This process, also called piering or leveling, involves leveling your foundation by underpinning it with concrete piers; the cost depends on how many piers are needed.

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

If you're building a new house, make sure that a soil report is 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, a few hundred dollars will cover an inspection and report by a structural engineer. The engineer can alert you to any current problems that need attention, and give you advice on avoiding future problems.

It's also important that the moisture around your foundation is at an appropriate level. As Allentown 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 expert should acquire the needed permits. You can request that the company provide a detailed explanation of its process and to see the paperwork and permits it has acquired to confirm everything is properly authorized per Allentown regulations.

Small hairline cracks might seem easy to take care of yourself, but in most cases, you should consult a professional before you begin any foundation maintenance. While you may not want to pay someone for work you feel you can handle yourself, foundation repair mistakes can cost you much more down the line.

Generally, foundation repair takes from one to several weeks. This range is wide because the timeline will vary greatly depending on factors like the type of repair needed and the size of your home. You should confer with your Allentown foundation repair professional for a more thorough timeline for your specific project.
