Get a deck built for damp ground, with ground-contact lumber, posts kept up off the dirt and a frame that can dry out. We cover Channahon.
Our crew builds new decks, replaces worn ones and repairs porches, start to finish. We frame in treated lumber, and you choose treated or composite for the boards and rails. Before anything goes on the house, we deal with the ledger: if the existing one is rotted, nailed on or missing flashing, it gets fixed first, because that joint is where most decks fail. Every job starts with a written estimate, and anything that changes along the way is priced on paper before we do it.
Channahon is off I-55 and I-80 for us, with Route 6 running through town. The Des Plaines and DuPage rivers, Channahon State Park and the I&M Canal are all close by, and if your yard sits low or holds water after a rain, the deck has to be built for it. That means lumber rated for ground contact where it is near the soil, posts set on concrete instead of buried in dirt, and enough open space under a low deck for air to move. A deck that cannot dry out is the one that rots from the bottom up.

Joists and beams near the soil use lumber treated for ground contact, not the lighter grade meant for above-ground use.
Posts sit on brackets atop poured footings, so they stay dry at the base instead of wicking water up from the soil.
We pull back the old ledger, check the rim of the house for rot, then flash it and bolt it back properly.
Rotted joists get sistered or replaced, and soft or split boards come out, so the surface is sound underfoot.
Stairs get matching rises and solid stringers, and guards and handrails go in at the height and spacing the code requires.
Front steps that have heaved or rotted get rebuilt, and porch columns get new bases where water has worked in.
We come out for free, walk the yard, and look at the drainage, the old deck if there is one, and the wall it ties into. You get a written scope that spells out the size, the lumber grade, the board material and the stairs, with the price. We pull the permit, schedule the inspections, and give you build dates we keep. If we find rot behind the ledger or under a board, we show you, price the fix in writing and wait for your yes, then we finish with a walkthrough of the whole deck.
