Keep your Romeoville deck level through every freeze and thaw with posts and footings that hold. We rebuild failing supports, replace rotted framing and build new decks from the ground up.
A deck is only as level as the posts and footings under it, and those are the parts most people never look at. Posts buried straight in the ground, or set on concrete that sits too shallow, rot or heave until the deck tilts and the railings go loose. We replace them with posts on proper footings below the frost line, with hardware that keeps the wood off the concrete. From there we repair or replace joists, beams and boards, rebuild stairs and railings to code, and make sure the ledger is flashed and bolted to the house.
We cover Romeoville in Will County off I-55, Route 53, Weber Road and 135th Street. If your Romeoville yard holds water after a rain or the ground under the deck stays damp, the bottom of each post is where rot starts, and you can often find it with a screwdriver before you can see it. Replacing posts under a standing deck takes temporary shoring, so we support the beam while the old post comes out and the new footing cures. That keeps the deck and the house connection from shifting while the work is underway.

New concrete footings go deep enough that freezing ground cannot lift them.
Rotted or heaved posts come out while the beam is shored, and new treated posts go in on standoff bases.
Cracked beams and joists with soft spots get replaced or sistered with new treated lumber.
Once the supports are right, the frame comes back to level so the door and the railings line up again.
We confirm the deck is bolted and flashed at the house, and correct it if it is not.
We build complete new decks in treated lumber or composite, from footings to railings.
We check every post and footing, probe the frame and write a free estimate that says which supports get replaced and why. When a post comes out and the footing below it is worse than it looked, we show you and price the extra work in writing before we pour anything. The village permit and inspections get scheduled into the plan, and we book the crew around the days we said. Before we leave, we put a level on the deck with you and check that the door and railings line up.
