Crawl Space Structural Repair Contractor in Greater Toronto

Repair your sagging crawl space & restore the structure -- without rebuilding!

Your crawl space plays a key role in your home's structural integrity by bearing the weight of the home through the foundation walls and crawl space support columns. However, many crawl spaces are designed with a support system that is either inadequate, rotting, or has soils underneath the support posts that cannot support the weight of your home.

At Clarke Basement Systems, we can restore your crawl space's structural integrity with our crawl space support jacks. If you have sagging or bouncy floors, our system is the proven, effective repair solution you need.

How crawl space supports fail

  • Sinking crawl space supports: Sometimes, crawl space support pillars are built on soils that are not strong enough to support the weight of your home. Over time, these supports will begin to sink into the soil. As they do, the floor they hold up will sink as well, leading to uneven floors and interior wall cracking.
  • Inadequate structural design: Sometimes, the contractor who builds a home will improperly space out the support beams that hold up your floor and interior structure. When this happens, the floor may sink in the spans between each support, leading to damage to your home structure.
  • Rotting floor joists: When crawl spaces are damp, humid, or experience flooding, they become an ideal environment for mold and rot. Termites, carpenter ants, wood-eating beetles, and other damaging insects may also feed on organic materials in the crawl space. As the wood deteriorates, it will no longer be able to support your home, leading to significant structural damage.
  • Foundation failure: The foundation walls themselves can fail in a large number of ways. Most commonly, these walls will be damaged by foundation settling due to poor supporting soils. It's also very common for the walls to buckle inwards due to pressure from expansive soils outside the home. If you have a structural issue with your foundation, it's important to contact a foundation specialist right away.

Our crawl space support post system

At Clarke Basement Systems, our solution to failing crawl space supports is the SmartJack® Crawl Space Stabilizer, an adjustable supplemental support system used for sagging crawl spaces. This system not only provides supplemental support to your failing structure -- it can also often lift failing floor joists or beams, restoring them to their original position.

This crawl space support system is unique in that it's made with strong, corrosion-resistant, galvanized steel. SmartJack® posts will not develop rust, meaning it will remain adjustable for years if you need to perform future adjustments.

Why choose the SmartJack® system

  • Fast, year-round installation: The SmartJack® can be installed year-round, with installations completing in about a day. There's no waiting time for concrete to cure!
  • Stronger crawl space support: Our crawl space support system can support vertical loads exceeding 60,000 pounds, which is far stronger than conventional concrete repairs.
  • Versatile installation: The SmartJack®'s portable size allows it to be installed in even the tightest of crawl spaces.
  • Superior support: Our support jacks do more than merely halt the downward movement of your floor. The SmartJack® may also be adjusted to try to lift the floor above to its original position.
