A beam begins to bend. Beams like this one provide mid-span support for floor joists in many crawl spaces. When floor joists weaken and bend, the floor above your crawl space will be uneven and bouncy.

The crawl space is an essential part of a home's structural support. Crawl spaces bear this weight through the foundation walls and crawl space support columns. Many crawl spaces have inadequate support due to mold decay, water damage, and soil settlement or sinking.

Once mold, moisture, or soil settlement becomes an issue, your home may experience sagging floors above the crawl space that could eventually break down if not repaired. That is why we offer warrantied crawl space support posts, which are a quick to install and provide a permanent crawl space structural repairs.

Crawl space support system

Crawl space structural support jacks installed in Springfield, VA

Strong, straight & adjustable. SmartJack® supports solve sagging floor problems in crawl spaces by stabilizing & leveling sagging beams.

When crawl space joists begin to sag because of age, mold, moisture, or pest damage, the floors above them will sag as well. This leads to uneven or "bouncy" floors in the living space, which are unpleasant for you and your family to deal with. This can also damage your home's value and curb appeal.

The SmartJack® Crawl Space Stabilizer is an adjustable supplemental support system used for sagging crawl spaces. It not only provides supplemental support to your failing structure, but can also 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 - which means that your system will not develop rust and remain adjustable for years.

The SmartJack® is available for installation throughout Virginia, including Falls Church, Arlington, Sterling and nearby areas.

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.

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.
