Sagging & Sinking Crawl Space Repairs in Greater Denver

A failing girder showing signs of compression damage in a Colorado home

A floor joist shows signs of compression due to the weight of the home — and too few support posts. Inadequate crawl space support leads to sinking floors, uneven floors, and damage to your structure.

The Problem:

Your crawl space is experiencing structural problems that are causing it to sink or sag in the middle.

What’s Happening:

Crawl spaces experience structural sagging for these three primary reasons:

Telltale Signs:

  • Tilting or sinking crawl space supports
  • Too few supports in the crawl space
  • Moist, rotting wood
  • Sagging, sloping, or uneven floors upstairs
  • Cracks in interior drywall
  • Door & window frames skewed and/or unlevel

How to Fix It:

Additional crawl space supports should be installed to ensure that your structure is properly stabilized. Mold and rot should also be addressed by installing a crawl space liner and removing excess moisture from the crawl space.

A moldy, unsupported girder (right) sinks under the weight of a home — due to an improperly installed crawl space support. If not addressed, could mean significant damage to the home.

Advantages To Our System:

At Rod Martin’s Complete Basement Systems, we recommend installing the IntelliJack System, which uses adjustable heavy duty steel crawl space jack posts. These posts install quickly in a home and provide the best solution for restoring stability to your structure.

The IntelliJack system can be installed in tight conditions, usually in less than a day. Made with galvanized steel for corrosion resistance, it can support vertical loads exceeding 60,000 lbs.

The adjustable design of our crawl space jack system means that sagging floors can not only be stabilized; they can also be restored to their original position in many cases.

To address the issue of poor supporting soils, each crawl space jack distributes the weight of the home through a precast concrete footing and a base of engineered fill material.

The IntelliJack is the only solution that addresses problem soils during crawl space restabilization!

Support Columns Spaced Too Far Apart

When a crawl space is built, columns made of block, brick, and even wood are located throughout the crawl space. These columns are designed to support the weight of the home above.

If these columns are spaced too far apart from each other, the beams and girders may be overloaded with weight, causing them to sag between the columns. When the girder sags, so does the floor above it.

Rot-Weakened Floor Joists/Girders

Because crawl spaces are often not sealed from the earth around them, excess moisture and humidity is a common problem. This moisture creates an environment where mold and rot can thrive, damaging the wood structure of your home.

The weakened girders and floor joists will be unable to continue to support the weight above. In time, the floor above the crawl space will become bouncy, soft, and will. In some extreme cases, the floor may even collapse.

Columns Settling Due To Weak Soil

Often, the soils that the crawl space supports are installed on are not strong or solid enough to support the weight being transferred from the home. Weak supporting soils will allow your existing crawl space columns to sink or settle, often creating a gap between the top of the column and the bottom of the girder it supports.

Once the column has settled, the girder above will begin to sag as well.
