Choose the right deck material for your Oswego yard with both options priced side by side. We build in treated lumber or composite and frame it to last.
The first decision on a new deck is the surface, and it shapes everything under it. Composite costs more up front and asks for little beyond a wash each year, while treated wood costs less to build and needs sealing or stain to hold up. Whichever you pick, we frame the deck on footings below the frost line, flash and bolt the ledger to the house, and build stairs and railings to the current code. We also resurface sound frames and replace rotted boards, joists, posts and ledgers on decks that need repair.
Oswego is on our regular route in Kendall County, reached on Route 34, Route 71, Orchard Road and Wolfs Crossing Road. If your Oswego deck faces south or west with no shade, the surface takes full afternoon sun, and that affects the choice: darker composite boards get hot underfoot, and treated wood in full sun dries out and checks faster without a good sealer. We bring samples to the estimate so you can see the colors in your own light. We also look at where the deck meets the house and how the yard drains, because water against the ledger or pooling under the frame matters more than the board you pick.

We price treated lumber and composite on the same estimate, along with the upkeep each one needs.
The frame is laid out to the spacing your decking calls for, which is often tighter for composite.
Boards are fastened the way that product is made to be installed, with gaps that let water drain through.
The deck connects to the house with bolts into the framing and flashing that keeps water out of the wall.
Steps and guards are built to the dimensions the village inspector checks.
A sound frame can take a new surface, and damaged framing gets fixed before it does.
We meet you in the yard with samples, measure the space and write a free estimate that prices the deck in both materials if you want to compare. Once you choose, the written scope lists the frame, the surface, the stairs and the railings, plus the permit. If something comes up during the build that changes the work, you get the price on paper and approve it before we do it. We finish by walking the deck with you and cleaning up the yard.
