How To Choose a Foundation Repair Company

Hiring a qualified foundation repair provider ensures you have someone who will inspect the damage thoroughly and make appropriate fixes. It's important to conduct research beforehand, focusing on the factors listed here.

Experience

Look for a local foundation repair company with extensive experience fixing all kinds of foundation problems. It should have expertise in the latest repair techniques and materials. Ask how long a provider has served your area.

Reputation

Looking through online reviews, checking the Better Business Bureau, and requesting local references helps verify that a company consistently 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 company you hire has the appropriate credentials, bonds, and coverage for liability and workers' compensation. In California, general contractors are required to be licensed by the Contractors State License Board in order to work on projects valued over $500. To be eligible for a license, an individual needs to have at least four years of related work experience in the last ten years (or be represented by someone who does), must pass both a business and law and a trade exam, and must be bonded. Individuals or businesses that have employees must also have workers' compensation insurance. Contractors may have to meet additional requirements to do certain concrete work.

Warranties

Choose a provider that offers transferable warranties of at least a decade, ideally up to lifetime guarantees, to fully 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

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

  • Can you provide a project scope and cost estimate in writing? Make sure to get quotes in writing to protect yourself from unexpected expenses.
  • What warranties do you offer? Reliable companies generally provide labor and materials warranties of at least 10 years.
  • 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 repairs would you recommend for this situation, and why? Your contractor may provide options such as carbon fiber, wall anchors, and steel piers. By asking, you can get an idea of what solutions a company offers and compare between providers.
  • Realistically, how long will the repairs take to complete? Look for companies that provide reasonable estimates.
  • What options do you have for financing? Providers often offer payment plans for larger foundation repairs.

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

Frequently Asked Questions About Foundation Repair in Downey, CA

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

On average, Downey homeowners spend about $2,705 on foundation repair. The amount you'll spend on foundation repair is based on several factors. Things like the type of repair needed, the extent of the damage, and the size of your home will all factor in. The easiest way to learn how much a job may cost is to talk to a local foundation repair expert and schedule a free inspection and estimate.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

For both leak repair and crack repair, a technician will come to your home, complete an inspection, and use various repair techniques to fix leaks or cracks. The cost of these procedures will vary greatly depending on the size and cause of the problem.

Stabilization involves reinforcing bowing walls by inserting carbon fiber or steel strips. The cost will depend on the material used and how many strips are needed. The cost of underpinning also varies. This process, also called leveling or piering, involves leveling your foundation by underpinning it with concrete piers; the cost will depend on how many piers are used.

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

When caring for your foundation, you should make sure it gets the right amount of moisture, especially in hot weather. Downey tends to be a very dry place, so in times of little rain you may need to water your foundation. Additionally, 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 reach out to a structural engineer for an evaluation. This will run you a few hundred dollars, but the consultation can net you a list of things to be aware of as well as more ideas to help you further protect your foundation. Finally, if you're building a new home, ensure that you 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 potential future issues.

A permit is normally required for foundation repair, but getting one isn't your responsibility. Your foundation repair provider should get all the permits and other documents required in Downey, and should be able to explain the process and/or provide the documents if asked.

If your foundation needs of waterproofing, you might notice signs like basement flooding, white powder or spots on your walls, uneven floors, hairline cracks, discoloration or odors, or signs of mold, mildew, or fungus.

Your options include interior and exterior waterproofing. Interior waterproofing typically is less expensive, and involves measures like the use of sealants or the installation of drains or sump pumps. Exterior waterproofing tends to be more expensive but more effective. Exterior waterproofing can involve things like external drains, landscaping changes, or physical barriers to stop water from getting into basements and crawl spaces.

In general, home insurance doesn't cover foundation repairs, unless the repair is to fix damage resulting from a covered weather event. It's a good idea to talk to your home insurance company before you begin any foundation repairs.
