How To Choose a Foundation Repair Company

Working with a qualified foundation repair provider is important for properly evaluating the damage and completing repairs correctly. We recommend focusing on these key factors.

Experience

We recommend choosing a local foundation repair provider with a well-established track record of fixing various foundation issues. These companies should have expertise in 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 asking for local references helps confirm that a provider consistently delivers top-notch workmanship and great service. Pay attention to any complaints about poor service or faulty repairs.

Licensing and Insurance

It's important to select a company that has the right licenses, bonding, and insurance 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 look up a company's New York business license on this website. There may be additional requirements for contractors to do certain concrete work.

Warranties

Look for a company that provides lengthy transferable warranties for a minimum of a decade, preferably lifetime guarantees, to back its foundation repairs. This demonstrates faith that its services are top-quality and safeguards you if issues come up in the future.

Questions To Ask Foundation Repair Companies

To compare foundation repair professionals, you should ask detailed questions such as:

  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • What warranties do you offer? Reliable companies usually provide labor and materials warranties of at least 10 years.
  • What repair method would you recommend for this specific situation and why? Your provider may offer options such as wall anchors, steel piers, and carbon fiber. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What foundation defects 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 attempting to bill you for unnecessary work.
  • How long will repairs realistically take? Look for providers that provide reasonable estimates.
  • Can you provide a complete written cost estimate and project scope? Asking for a quote in writing helps shield you from unexpected costs.

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 delivers long-lasting, high-quality repairs. Swiftly addressing foundation issues helps prevent further structural damage.

Frequently Asked Questions About Foundation Repair in East Islip, NY

There are certain signs that your foundation is in need of repair. These can include:

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

On average, East Islip homeowners pay roughly $2,885 for foundation repair, although the total cost will depend on several factors. The easiest way to get an estimate for the cost of your specific job is to ask for quotes from a handful of local foundation repair companies. The amount you pay for a job will be affected by things like the size of your house and type of repair(s) needed.

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 remedy leaks or cracks. The cost of these procedures will vary greatly depending on the size and root cause of the issue.

Stabilization involves reinforcing bowing walls by inserting carbon fiber or steel strips. The cost will depend on the material used and the number of strips required. The cost of underpinning also varies. This process, sometimes referred to as piering or leveling, involves underpinning your foundation with concrete piers to level it; the cost is based on how many piers are used.

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

To protect your foundation, you should make sure that it has the right amount of moisture. East Islip sees more rain than many places, so be sure that your gutters and landscaping are arranged to prevent too much water from collecting near your foundation. Also make sure that you quickly identify and fix any leaking pipes or gutters.

If you have any concerns about your foundation, you can contact a structural engineer for an evaluation. This will cost a few hundred dollars, but the engineer's consultation can provide you with a list of things to look out for as well as steps you can take to further protect your foundation. Lastly, if you're constructing a new house, ensure to have a soil report done. This can provide information regarding how well the soil on your property will be able to support a foundation, and can highlight potential future issues.

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

Generally, foundation repairs will positively affect your home's value. In some cases, foundation repairs may be considered a capital improvement, which might qualify you for tax breaks. A capital improvement is generally defined as one that will add to your house's overall value, prolong its life, or adapt it to new uses. Talk to your New York tax professional for more information.

The length of time a foundation repair takes varies greatly based on the kind of repair required and the size of your home. Most repairs will take anywhere from one to several weeks. Consult your East Islip foundation repair expert for the specific timeline for your project.
