Get a deck laid out around how you use the back yard, with the stairs, the grill spot and the table where they make sense. We cover Downers Grove.
A new deck with us covers the design, the permit, the footings, the frame, the boards, the stairs and the railings, built by one crew. You pick treated lumber or composite, and we price both so the trade-off is clear: composite costs more now and asks for little upkeep, while treated wood costs less and needs sealing. The ledger gets flashed and bolted to the house on every build, since that connection is where most decks fail. Nothing starts until you have the plan and price in writing.
Downers Grove is on our route along I-88 and I-355, with Ogden Avenue, Butterfield Road and Main Street carrying us across town, from the Metra station downtown to the side streets. Where a back door opens onto a deck, the layout decides how it lives: which way the stairs land, where the grill can sit clear of the siding, and whether a table fits without blocking the door. We sketch those choices before we price anything. If your house also has a front porch with tired steps or a sagging rail, we can fold that into the same estimate.

We place the stairs, the table area and the grill spot on a sketch before we price the build.
Posts sit on concrete footings set below the frost line, and the frame is sized for the span and the load.
Flashing keeps water out of the house rim, and structural bolts hold the ledger tight.
Treated or composite boards go down with the fasteners the board calls for, spaced so water drains.
Stairs get even rises and a graspable handrail, and the guards meet current code.
We rebuild worn porch steps, replace rotted boards and set railings that hold firm.
We start with a free visit to measure, look at the back wall and the door, and talk about how you want to use the space. You get a sketch and a written scope with the size, materials and stair plan, plus the price. We pull the permit with the village and schedule the inspections, then lock in build days you can plan around. Any change, from a wider stair to an extra step, is priced on paper and approved by you first, and the job ends with a walkthrough on the finished deck.
