How To Choose a Foundation Repair Company

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

Experience

We suggest choosing a local foundation repair company with a long history of fixing various types of foundations. These companies should have expertise in the latest techniques and materials. Ask providers how long they've served your area.

Reputation

Reading online reviews, checking the Better Business Bureau, and requesting local references helps verify that a company regularly 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 right licenses, bonds, and insurance for liability and workers' compensation. In New Jersey, contractors must provide proof of liability insurance and register as a Home Improvement Contractor with the Division of Consumer Affairs There are no other state-level licensing requirements, but you should be sure to check with your city, county, or municipal government to learn about any local regulations. There may be additional requirements for contractors to do certain work with concrete.

Warranties

Opt for a provider offering long transferable warranties of at least 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:

  • What financing options do you offer? Many providers offer payment plans for larger foundation projects.
  • Realistically, how long will repairs take to complete? Look for companies that provide reasonable estimates.
  • What repairs would you recommend for my situation, and why? Your contractor may consider options such as wall anchors, steel piers, and carbon fiber. Asking allows you to compare suggested solutions between companies.
  • Can you provide a complete written cost estimate and project scope? Getting quotes in writing helps protect you from unexpected costs.
  • What are some likely causes of my issues based on your inspection? Look for clear explanations and solutions in the answer. Companies that provide vague answers may be attempting to bill you for unnecessary work.
  • What warranties do you offer? Reputable providers generally provide labor and materials warranties for at least 10 years.

Thoroughly reviewing foundation repair companies helps homeowners identify the best fit for their needs. A company that can answer the above questions likely performs durable, long-lasting repairs. Fixing foundation problems right away decreases the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Iselin, NJ

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

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

On average, Iselin homeowners pay roughly $3,536 for foundation repair, although the actual cost will vary widely depending on several factors. The easiest way to get an estimate for the cost of a specific project is to solicit quotes from a handful of 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 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 repair expert will perform an inspection and complete any repairs necessary to remedy cracks or leaks. Costs will depend on the size and cause of the issue.

Underpinning, also called piering or leveling, 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 fixes bowing walls by reinforcing them with carbon fiber or steel strips, and the cost will depend on the material chosen and how many strips are used.

Lastly, waterproofing is an overarching term for a category of repairs designed to stop 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 planning to waterproof your foundation.

If you're building a new home, make sure that a soil report is 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 potential future issues. If you have concerns about an existing home, for a few hundred dollars, you can get an inspection and report by a structural engineer. They can point you to any things that could use some attention, and give you advice on avoiding future problems.

Also ensure that the moisture around your foundation is at an appropriate level. As Iselin 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 gutters or pipes, so you can get them repaired quickly.

Foundation repair usually requires a permit, but applying for one isn't your responsibility. Your foundation repair professional should put together the permit and all other documents required in Iselin, and should be able to provide the documents and/or explain the process before starting work.

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

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

You may be able to handle small hairline cracks on your own, but in general, it's a good idea to consult a professional before you start any foundation maintenance. While you may balk at the idea of paying someone for work you feel you can handle yourself, mistakes made during foundation repair can be even more costly in the future.
