Common Causes of Foundation Problems in Ontario

A home in Ontario might experience foundation issues for numerous reasons. Some are specific to the local environment, while others are widespread nationwide. They include:

  • Standing water: Pooling water around your home can be a menace to your foundation, especially when it gathers in areas your drainage system doesn't cover.
  • Improper modifications: Roofing or landscaping work that wasn't completed to standard could result in your foundation settling.
  • Aging plumbing: The average Ontario home construction year is 1975. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start to erode, leaking water could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can encroach on a home's foundation through crevices, and may create stress that leads to your foundation breaking, pipes rupturing, and overall structural destabilization.

How to Choose the Best Foundation Repair Company

Your home's stability relies on its foundation. It's important to choose the best team possible. Focus your research on these characteristics:

Licensing and Experience

The Golden State issues many different kinds of contracting licenses, and foundation companies often have more than one. You can verify a company's licensing information through the Contractors State License Board, a division of the California Department of Consumer Affairs. Look for a company with a General Building Contractor, General Engineering Contractor, C-8 Concrete, or C-61 Pile Driving credential. You can also get a sense of a company's experience through the information its team gives you. Ask about its inspection methods, local building regulations, permit-pulling procedures, and fees.

Another way to gauge a company's reputation is to look at its website. There, you can learn how long it's been in business and its trade credentials. It might also share insights and knowledge through blog posts, podcasts, or videos.

Customer Reviews

When you're researching a company's standing, check out its Better Business Bureau (BBB) profile. There, you can find its "letter grade" rating and a list of customer reviews, both positive experiences and complaints. Remember that negative feedback doesn't necessarily mean a contractor is unqualified. The BBB shows how companies resolve complaints. A responsive team that works toward amicable outcomes is a good one. Don't work with a contractor if you don't see good communication about problems.

Foundation Repair Cost in Ontario

For minor foundation fracturing and settling issues, you may pay as little as $1,800. However, if there is significant destruction, the average cost will be around $2,800. More involved jobs involving digging, helical piers, or extensive concrete leveling could run you $6,800. Below are the average foundation repair costs for common issues.
