Trust every connection on your Crest Hill deck, from the bolts at the house to the hangers under each joist. We repair, rebuild and build new decks and porches with hardware made for treated lumber.
A deck is wood held together by metal, and the metal is often what quits first. Joist hangers rust, nails pull out of the house, and the bolts at the ledger were sometimes never installed at all. We check every connection, replace corroded hangers and hardware with coated or stainless parts rated for treated lumber, and bolt the ledger to the house with flashing over it. On top of that, we resurface sound decks, replace rotted framing, rebuild stairs and railings to code and build new decks in treated lumber or composite.
We reach Crest Hill on I-55, Route 30, Route 53 and Weber Road, and we cover it every week in Will County. If your Crest Hill deck has rust streaks running down from the joist hangers, or hangers with half their nail holes empty, the frame is relying on less than it should. Railing posts are the other weak point, because a post held on with a couple of screws can feel fine until someone leans on it. We push hard on every railing post during the estimate and tell you which ones need new blocking and bolts.

Rusted or half-nailed hangers come off and new ones go on with every hole filled with the right fastener.
We use coated or stainless connectors and screws, since plain steel corrodes in contact with treated wood.
Bolts go through the ledger into the house rim, and flashing over the top sends water past the joint.
Loose guard posts get new blocking and through-bolts so they hold when someone leans on them.
Rotted joists, beams and decking get replaced with new treated lumber.
We build new decks and porch steps from the footings up, in treated lumber or composite.
We get under the deck with a light, check every hanger, bolt and post, and write a free estimate that lists the hardware and framing work separately from the surface. If we find more damage once boards or hangers come off, you get a written price and decide before we do it. When the work is structural, we pull the permit with the City of Crest Hill and schedule the inspection. At the end you can lean on every railing post yourself while we walk the deck together.
Send a photo of the hangers under your deck to (815) 585-1750, or call to set up a free estimate. You get the hardware and framing repairs listed in writing.
