Personal Information

Sagging Crawl Space

Have you noticed unlevel or bouncy floors in your home?

If so, there is a good chance your crawl space is experiencing structural problems causing it to sink or sag in the middle.

Crawl spaces experience structural sagging for three primary reasons:

  • Support columns are spaced too far apart
  • Joists, girders, and posts are weakened by rot
  • Columns are settling due to weak soil or poor footings

Inadequate crawl space support leads to sinking floors, uneven floors, and damage to your structure. If you experience any of the following, it's time to call a professional:

  • Tilting or sagging crawl space supports
  • Too few supports
  • Moist, rotting wood
  • Sagging, sloping, or uneven floors
  • Cracks in interior drywall
  • Cracks in door & window frames that are skewed and unlevel

The sooner you call, the better. We will send out our team to evaluate your sagging crawl space and determine if you need repair.

SmartJack® Crawl Space Support System

For our clients with sagging crawl spaces who need structural support, we recommend the SmartJack® System.

Advantages of SmartJack® for Sagging Crawl Spaces

This system is state-of-the-art and offers clients many advantages over other crawl space repair options.

Galvanized Steel Supports

Made with galvanized steel for corrosion resistance, SmartJack® can support vertical loads exceeding 60,000 lbs. The adjustable design of our crawl space jack system means that sagging crawl space floors can not only be stabilized, they can also be restored to their original position in many cases.

The heavy-duty steel crawl space jack is adjustable. The steel posts install quickly and provide the best solution for restoring stability to a house.

Fast Installation

The SmartJack® system can be installed in tight conditions, usually in less than a day. It will not disrupt your home or landscaping.


Each crawl space jack distributes the weight of the home through a precast concrete footing and a base of engineered fill material. The SmartJack® is the only solution that addresses problem soils during crawl space restabilization!

Installing the SmartJack® for Sagging Crawl Spaces

Installing the SmartJack® is a fast, five-step process:

How to NOT fix a sagging crawl space

Here are fixes that LRE Foundation Repair does NOT recommend for sagging crawl spaces:

Concrete columns

Crawl space girders or beams are sometimes supported by columns made from concrete blocks. Once the column has been built and the mortar has cured, the extra space between the uppermost block and the floor girder above is filled with wooden spacers or shims. This is a very slow, time-consuming process that results in a completed column that isn't adjustable, meaning additional shimming will be needed as the concrete column settles or the wood girder shrinks.

Additional shimming

This is a cheap fix solution for repairing a girder and floor that have sagged because of settled concrete columns. Temporary jacks are used to lift the girder, and wooden shims are pushed between the existing column and the floor girder. The jacks are then removed. This is a short-term fix only - the concrete columns will continue to settle, requiring additional shimming and maintenance in the future.

Light-duty jack posts

Skinny, light-duty jack posts for fixing crawl space floors are available at many hardware stores and home centers. This type of adjustable steel post is often installed on top of a concrete block that rests on the ground in the crawl space. Unfortunately, these posts hold very little weight, have poor stability and are difficult to adjust. Also, they won't compensate for poor supporting soils in the crawl space.
