The main beam carries the house. This carries the main beam.
Foundation jacks are heavy duty adjustable steel supports for the primary beams and girders of your home. Foundation jack installation restores the load path from your floors down to solid ground and holds it there.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What to know about foundation jack installation, and when it's the right call.
The principle is load transfer. Your home's weight wants a continuous route from the roof down through the framing into the ground, and a foundation jack rebuilds the broken segment of that route in steel and concrete. The footing comes first, engineered for the concentrated load a main beam delivers, because the ground is where most of these failures started and no support outperforms what it stands on. The jack is then set and extended to meet the beam. Lifting is done gradually: a structure that settled over years is raised in small increments, with pauses that let the framing, finishes, and openings above adjust without cracking. Elevation readings guide every stage, so the lift stops exactly where the measurements say it should rather than where it looks about right. Once the beam reaches the corrected height, the jack is locked in place and stays as part of the structure. It can still be adjusted later, which matters in this region: soil that moves seasonally is easier to live above when the supports can be adjusted instead of rebuilt. Foundation jacks handle the heavy load points; the rest of the framing repair system has its own repairs. Lighter spans are supported with crawl space jacks, failed wood supports are renewed through post and pier replacement, and a beam too far gone to lift is handled by beam and girder replacement before any jack goes to work.
The symptoms that usually lead to foundation jack installation are on the framing repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install foundation jack installation.
Free evaluation and load assessment
A specialist maps floor elevations, inspects the main beams and their supports, and identifies where the load path failed and what it will take to restore it.
Engineer and pour the footings
Footings sized for the concentrated loads of main beams are excavated and poured at each jack location.
Set the jacks
Heavy duty steel jacks are placed on the cured footings and fitted to the beams above through steel bearing plates.
Lift in controlled stages
The beam is raised in small increments with elevations monitored throughout, letting the structure above adjust safely.
Lock, document, and verify
Each jack is locked at the corrected height and final elevations are compared against the starting survey, so you see exactly what changed.
Bouncy floors, done bouncing.
Galvanized steel jacks go under the sagging beam, each on its own footing, and thread up until the floor is flat. Sag, bounce, and the sloping hallway all come from the same missing support.

Scale and role. Crawl space jacks typically support girders and joists at intermediate points, correcting local sags. Foundation jacks are the heavier duty version of the same idea, installed under main beams and primary load points where the concentrated weight is greatest. Many projects use both, and the evaluation determines the right mix for your framing.
