Frequently Asked Questions About Foundation Repair in Ontario, CA

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

The total cost of foundation repair depends on a number of factors. Things like the size of your home, the extent of the damage, and the type of repair needed will all help determine the cost. On average, Ontario homeowners spend about $3,940. The easiest way to find out how much a job could cost is to contact 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.

Leak repair and crack repair involve a technician coming to your home, completing an inspection, and using various repair techniques to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and cause of the issue.

Stabilization is the process of fixing 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 piering or leveling, involves underpinning your foundation with concrete piers to level it; the cost is based on how many piers are needed.

If you're interested in waterproofing your foundation or basement, we suggest looking for a waterproofing specialist. This process might include indoor waterproofing, outdoor waterproofing, or both.

Signs that your foundation needs waterproofing include discoloration or odors, white powder or spots on your walls, uneven floors, basement flooding, hairline cracks, or signs of mold, fungus, or mildew. Your contractor can inform 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 costly than exterior waterproofing. Exterior waterproofing can involve things like applying physical barriers to basements and crawl spaces, installing exterior drains, or making landscape changes.

Your foundation repair company should be the one to get the permits. You can ask the company to provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to verify that everything is properly authorized per Ontario regulations.

Although some foundation issues may appear small and not worth the cost to fix, when left untreated, they can cause larger and more expensive problems in the future. Foundation issues can also have underlying causes that are not clear until after a professional inspection. It's important to handle these underlying issues as soon as possible. For these reasons, we recommend you don't procrastinate on foundation repairs.
