How To Choose a Foundation Repair Company

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

Experience

Look for a reputable local foundation company with significant experience in successfully fixing a wide range of foundation problems. Technicians should have expert-level understanding of current repair methods and materials. Contact the company to ask how long it’s served your community.

Reputation

Looking through online reviews, checking the Better Business Bureau, and asking for local references helps verify that a company regularly provides good workmanship and good service. Pay attention if you see multiple complaints about poor service or faulty repairs.

Licensing and Insurance

It's important to select a provider that has the correct credentials, bonding, and insurance for liability and workers' compensation. You typically want to look for a general contractor license. In Connecticut, this may be called a Home Improvement Contractor license. These licenses are controlled by the Department of Consumer Protection. 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, or preferably lifetime guarantees, to back its repair work. This demonstrates faith that its services are top-quality and safeguards you if issues arise in the future.

Questions To Ask Foundation Repair Companies

When comparing potential foundation repair companies, be sure to ask detailed questions such as:

  • What do you see as the likely cause of the problem 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.
  • How long will repairs realistically take? Look for companies that provide reasonable estimates.
  • What guarantees do you offer? Reputable providers usually provide labor and materials warranties for at least 10 years.
  • What repairs would you recommend for this situation, and why? Your contractor may consider options such as wall anchors, carbon fiber, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • What financing options do you have? Providers often offer payment plans for larger foundation repairs.
  • Can you provide a complete written cost estimate and project scope? Getting the details in writing helps shield you from unexpected costs.

Carefully assessing foundation repair companies helps homeowners locate the best fit for their needs. A company that can answer the above questions likely delivers durable, long-lasting repairs. Repairing foundation problems right away decreases the risk of future structural damage.

Frequently Asked Questions About Foundation Repair in Kensington, CT

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

On average, Kensington homeowners pay around $2,932 for foundation repair, although the total cost will change based on several factors. The fastest way to get an estimate for the cost of a specific job is to ask for quotes from one or more local foundation repair companies. Your total cost will be influenced 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 what they sound like: 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 leveling or piering, is the process of leveling your foundation by underpinning it with large concrete piers. The price will be based on how many piers are used. The price of stabilization is also variable. This process fixes bowing walls by reinforcing them with carbon fiber or steel strips. The cost will depend on what material is used and how many strips are used.

Finally, waterproofing is an overarching term for a category of repairs intended to prevent water from getting into your foundation or basement. This can include 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.

When caring for your foundation, you should make sure that it gets the proper level of moisture. Kensington 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. You should also make sure that you promptly identify and repair any leaking gutters or pipes.

If you have any concerns about your foundation, you can call 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 potential concerns as well as more ideas to help you further protect your foundation. Finally, if you're constructing a new house, ensure to have a soil report done. This can provide information about how well the soil on your property will be able to support a foundation, and can highlight any potential future problems.

Your foundation repair provider should acquire the needed permits. You can request that the company provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to make sure everything is properly authorized per Kensington regulations.

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

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

It's a good idea to talk to your foundation repair company about this question before beginning any project. Generally, yes, you should be able to remain at home while foundation work is being done.
