How To Choose a Foundation Repair Company

You need a good foundation repair company to accurately evaluate issues and make appropriate repairs. Do thorough research and focus on these important factors when looking for the right company.

Experience

We recommend looking for a local foundation repair provider with a proven reputation for fixing various types of foundations. These companies should have deep knowledge of the latest techniques and materials. Ask providers how long they've served your area.

Reputation

Carefully reading online reviews, checking the Better Business Bureau, and getting local references helps confirm that a company consistently delivers high-quality work and great service. Pay attention to any complaints about poor service or faulty repairs.

Licensing and Insurance

Make sure any professional you hire has the right licenses, bonds, and coverage for liability and workers' compensation. There are no state-level licensing requirements for general contractors in New York, but there may be regulations at the city or county level, so make sure that you check with your local government. You can confirm that a company holds a valid New York business license on this website. There may be additional requirements for contractors to do certain concrete work.

Warranties

Opt for a provider offering transferable coverage for 10+ years, ideally lifetime guarantees, to completely back its repair work. This exhibits belief in the quality and durability of the repairs and offers protection should problems develop later.

Questions To Ask Foundation Repair Companies

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

  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to shield yourself from unexpected costs.
  • What repairs would you recommend for this situation, and why? Your contractor may provide options such as wall anchors, steel piers, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • Realistically, how long will repairs take to complete? 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 guarantees do you offer? Reliable companies usually provide labor and materials warranties that last at least 10 years.
  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.

Taking time to carefully evaluate foundation repair contractors will help homeowners find the right company for their needs. A company that can thoroughly answer these questions is likely one that offers long-lasting, high-quality repairs. Swiftly addressing foundation issues reduces the risk of further structural damage.

Frequently Asked Questions About Foundation Repair in Lewisboro, NY

If your foundation is in need of repair, you may notice a number of symptoms. Outside, you might notice a crumbling or cracking foundation or cracks in your driveway. Your ground level or basement may have uneven or cracked floors. You might notice windows and doors that are sticking in their frames, or frames that are skewed. You could also notice buckling, cracking, or bowing walls.

On average, Lewisboro homeowners pay roughly $3,465 for foundation repair, although the cost will vary widely depending on several factors. The best way to get an estimate for the cost of your specific project is to get quotes from a handful of local foundation repair companies. The total price will be determined by things like the size of your house and type of repair(s) needed.

The main 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 take necessary measures to remedy cracks or leaks. Costs will vary based on the size and cause of the issue.

Underpinning, also called leveling or piering, is the process of leveling your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are needed. The price of stabilization is also variable. This process reinforces bowing walls with steel or carbon fiber strips. The total cost will depend on the material and how many strips are used.

Lastly, waterproofing is an overarching term for a category of repairs that help prevent water from getting into your foundation or basement. This can involve exterior waterproofing, interior waterproofing, or both, and costs can vary greatly. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

When building a new house, have a soil report completed. This report contains 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 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 current problems that need attention, and advise you on avoiding future problems.

You also want to make sure that the moisture around your foundation is at an appropriate level. As Lewisboro 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. You should also stay vigilant for leaky pipes or gutters and repair them promptly.

Foundation repair usually requires a permit, but applying for one shouldn't be your responsibility. Your foundation repair provider should get the permit and all other documents required in Lewisboro, and should be able to provide the documents and/or explain the process if asked.

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

Interior waterproofing can involve the use of sealants or the installation of sump pumps and drains and tends to be less expensive than exterior waterproofing. Exterior waterproofing can involve things like applying physical barriers to basements and crawl spaces, installing exterior drains, or changing your landscaping.

Although some foundation issues may appear small and not worth the cost to repair, when left untreated, they can result in much larger and more expensive problems in the future. Foundation problems may have underlying causes that are not readily apparent until after a professional inspection. It's important to fix these underlying issues as soon as possible. For these reasons, we recommend you don't procrastinate on foundation repairs.
