How To Choose a Foundation Repair Company

Hiring a qualified foundation repair provider 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

Look for a well-established local company with extensive experience successfully completing all manner of foundation repairs. These providers have specialized expertise using the latest materials and methods. Ask how long a company has been serving your area.

Reputation

Reading online reviews, checking the Better Business Bureau, and requesting local references helps confirm that a company consistently provides good workmanship and good service. Pay attention if you see numerous complaints about poor service or faulty repairs.

Licensing and Insurance

Make sure any professional you hire has the appropriate credentials, bonds, and insurance for liability and workers' compensation. 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 city, county, or municipal government to find out if there are local contractor licensing requirements. There may be additional requirements for contractors to do certain concrete work.

Warranties

Look for a provider that offers lengthy transferable warranties for a minimum of a decade, preferably lifetime guarantees, to back its repair work. This demonstrates that the company stands behind its work and safeguards you if issues come up in the future.

Questions To Ask Foundation Repair Companies

As you evaluate potential foundation repair companies, make sure to ask in-depth questions such as:

  • 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 a vague answer, it may be trying to bill you for extra work.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.
  • What warranties do you provide? Reputable providers generally provide labor and materials warranties that last at least 10 years.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • What exact repair method would you recommend for this specific situation and why? Your provider may offer options such as wall anchors, carbon fiber, and steel piers. Asking allows you to compare suggested solutions between companies.
  • Can you provide a complete written project scope and cost estimate? Getting the details in writing helps protect you from unexpected expenses.

Thoroughly reviewing foundation repair companies helps homeowners identify the best fit for their needs. A company that can answer the above questions likely delivers durable, high-quality repairs. Addressing foundation problems quickly lowers the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Radnor, PA

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

  • Visible crumbling or cracks in your foundation
  • Uneven ground-level 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, Radnor homeowners pay about $3,066 for foundation repair, although the cost will depend on several factors. The fastest way to get an estimate for the cost of a specific job is to solicit quotes from a handful of local foundation repair companies. The amount you pay for a job will be determined by things like the type of the repair(s) and the size of your house.

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

Leak repair and crack repair involve a technician coming to your home, completing an inspection, and using various measures to fix leaks or cracks. The amount you spend can vary greatly depending on the size and root cause of the issue.

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

If you're looking to waterproof your foundation or basement, we suggest finding a waterproofing specialist. This process can include indoor waterproofing, outdoor waterproofing, or both.

If you're 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 provide you with a heads-up about any potential future issues. If you have concerns about an existing home, a few hundred dollars will cover an inspection and report by a structural engineer. They can alert you to any current problems that could use some attention, and give you advice on how to avoid future problems.

Also ensure that the moisture around your foundation is at an appropriate level. As Radnor 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.

Permits are needed for most foundation repairs, but obtaining one isn't your responsibility. Your foundation repair provider should get all the permits and other documents required in Radnor, and should be able to provide the documents and/or explain the process before starting work.

Indicators that your foundation needs waterproofing include uneven floors, hairline cracks, basement flooding, white powder or spots on your walls, discoloration or odors, or signs of mold, fungus, or mildew. Your contractor can determine whether you need interior or exterior waterproofing.

Interior waterproofing can involve the installation of sump pumps and drains or the use of sealants and generally is less costly than exterior waterproofing. Exterior waterproofing can involve things like applying physical barriers to crawl spaces and basements, making changes to your landscaping, or installing exterior drains.

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 can sometimes qualify you for tax breaks. A capital improvement is generally defined as one that adds to your house's overall value, prolongs its life, or adapts it to new uses. Talk to your Pennsylvania tax professional for more information.
