How To Choose a Foundation Repair Company

You need a good foundation repair company to properly assess issues and make appropriate repairs. Do your research and focus on these factors when selecting the right company.

Experience

Look for a well-established local company with many years, ideally decades, of experience successfully handling all manner of foundation repairs. These companies have specialized expertise with the latest materials and methods. Ask how long a company has been serving your area.

Reputation

Thoroughly reading online reviews, checking the Better Business Bureau, and asking for local references helps verify that a provider consistently delivers high-quality work and great service. Pay attention to any complaints about poor service or faulty repairs.

Licensing and Insurance

Only hire providers that are properly licensed, bonded, and have both workers compensation and liability insurance. 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. Contractors may have to meet additional requirements to do certain work with concrete.

Warranties

Choose a provider that offers long transferable warranties of at least a decade, ideally up to lifetime guarantees, to back their foundation repairs. This demonstrates confidence in the quality of their work and offers protection if future issues arise.

Questions To Ask Foundation Repair Companies

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

  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide unclear answers may be attempting to bill you for extra work.
  • What repairs do you recommend for this situation, and why? Your contractor may provide options such as carbon fiber, steel piers, and wall anchors. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What options do you have for financing? Many providers offer payment plans for larger foundation projects.
  • Can you provide a cost estimate and project scope in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What guarantees do you offer? Reliable companies usually provide labor and materials warranties that last at least 10 years.
  • Realistically, how long will repairs take to complete? Look for providers that provide reasonable estimates.

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

Frequently Asked Questions About Foundation Repair in Islip, NY

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

On average, Islip homeowners pay roughly $2,884 for foundation repair, although the total cost will change based on several factors. The best way to get an estimate for the cost of your specific job is to get quotes from one or more local foundation repair companies. Your total cost will be affected by things like the size of your house and type of repair(s) needed.

The primary 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 repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will vary depending 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 used. The price of stabilization varies similarly. This process reinforces bowing walls with steel or carbon fiber strips. The cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a number of jobs designed to stop water from getting into your foundation or basement. This can involve exterior waterproofing, interior waterproofing, or both, and the price can vary greatly. We recommend contacting a waterproofing specialist if you're interested in waterproofing your foundation.

To protect your foundation, you should make sure that it has the right amount of moisture. 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 promptly identify and repair any leaking gutters or pipes.

If you think there may be any problems with your foundation, you can call a structural engineer for an evaluation. This will cost a few hundred dollars, but the consultation can provide you with a list of potential concerns as well as more ideas to help you further protect your foundation. Finally, if you're building a new home, make sure 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 any potential future problems.

Foundation repair usually requires a permit, but getting one isn't your responsibility. Your foundation repair provider should obtain all the permits and other documents required in Islip, and should be able to explain the process and/or provide the documents before starting work.

Foundation repairs can sometimes, foundation repairs can be considered capital improvements if they meet the criteria of an improvement that adds to your house's overall market value, prolongs its life, or adapts it to new uses. Making capital improvements sometimes helps you qualify for tax breaks. (Contact your New York tax professional for the most accurate information.) Tax breaks aside, foundation repairs will generally have a positive effect on your home's value.

While some foundation problems might seem small and not worth the cost to fix, when left untreated, they can result in larger and more expensive problems later on. Foundation issues can also have underlying causes which are not obvious until after a professional inspection. It's important to fix these underlying issues as soon as possible. For these reasons, we advise against procrastinating on foundation repairs.
