Today's Homeowner looks at dozens of datapoints on foundation companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
If your foundation needs repairs, it may manifest in a number of ways. Outside your home, you might notice a crumbling or cracking foundation or cracks in your driveway. Your ground floor might have floors that are uneven or cracked. You might notice windows and doors sticking in their frames, or that the frames are skewed. You could also notice buckling, bowing, or cracking walls.
The amount you'll spend on foundation repair depends on several factors. Things like the extent of the damage, the type of repair needed, and the size of your home will all factor in. On average, Walnut homeowners spend about $4,539. The fastest way to learn how much a job could cost is to contact a local foundation repair expert and schedule a free inspection and estimate.

The main types of foundation repair are 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 take necessary measures to remedy cracks or leaks. The price will vary based on the size and cause of the problem.
Underpinning, also called piering or leveling, is when a contractor levels your foundation by underpinning it with large concrete piers. The cost will depend on how many piers are needed. 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 the material chosen and how many strips are used.
Finally, waterproofing is an overarching term for a category of repairs intended 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 planning to waterproof your foundation.
Permits are needed for most foundation repairs, but obtaining one is not your responsibility. Your foundation repair professional should obtain the permit and all other documents required in Walnut, and they should be able to explain the process and/or provide the documents before starting work.
Usually, your foundation repair expert will be licensed as a general contractor. In California, general contractors need to be licensed by the Contractors State License Board in order to work on projects valued at $500 or more. To obtain a license, an individual must 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 law and business and a trade exam, and must be bonded. Individuals or businesses that have employees must also have workers' compensation insurance. There may be additional requirements for contractors to do certain work with concrete.
Foundation repair, especially extensive repairs like basement waterproofing, should last a long time. This is especially true if you hire a reputable company. By solving systemic foundation issues, or reinforcing critical areas, you reduce your risk of future problems.
