Crawl Space Support Posts
Sagging floors, weakened beams, and unstable support systems can be signs of structural issues beneath your home. DBS Repair provides professional Crawl Space Support Posts using the SmartJack® system to permanently stabilize and lift sagging crawl space beams and girders. Installed on a foundation-grade steel base and adjustable for future leveling, these support posts help restore structural integrity and improve the long-term stability of your home.
SmartJack® Crawl Space Support Posts:
Permanent, Adjustable Floor Support
The SmartJack® system is a patented adjustable steel support post engineered specifically for crawl space floor beam support. It replaces failing wood posts, deteriorating block stacks, and inadequate shimmed supports with a permanent, galvanized steel solution that will not rot, rust, or shift.
Each SmartJack® post is installed on a steel base plate that is set in poured concrete, creating a stable, engineered footing directly under the sagging beam. The post is then adjusted to lift the beam back toward its original position.
Because SmartJack® posts are adjustable, our crews can return in the future to make additional incremental lifts if needed without reinstalling or replacing the system.

What to Expect
1.
Free on-site inspection and estimate
A DBS foundation specialist visits your home to assess wall movement, measure deflection, and determine the correct anchor type and placement.
2.
Base plate footing preparation
At each post location, a hole is excavated and a concrete footing is poured to engineered specifications to serve as the base of the SmartJack® post.
3.
Post installation and beam engagement
The galvanized steel post is set on the base plate and the top bracket is positioned under the sagging beam or girder.
4.
Incremental lift
The post is adjusted to begin lifting the beam. Lift is applied incrementally to avoid cracking drywall or finishes above.
5.
Cleanup and documentation
Crawl space is cleaned, warranty documentation is issued, and adjustment instructions are provided for future maintenance lifts.
