A Willow Springs deck that stands firm on a hillside and holds up under the trees, with the footings and the house connection done right.
On a sloped yard, the posts do most of the work: they get taller, they need bracing, and the footings under them have to sit on undisturbed soil below frost. We build decks in treated lumber or composite on that kind of foundation, and we repair existing decks where posts have rotted at grade or footings have heaved. The ledger at the house is flashed and bolted, because that connection is where most decks start to fail. Every stair and railing goes in to current code.
We cover Willow Springs from I-294 and Archer Avenue, and Willow Springs Road takes us through the village to the Des Plaines River and the forest preserves along it. It is a Cook County village on the river. If your lot backs up to trees, the deck spends more of the day in shade and stays damp longer after rain. That is hard on treated boards and on the tops of joists, so we talk through composite, joist tape and board spacing for airflow before you pick the decking.
Holes are dug below frost to undisturbed soil, with concrete sized for the load each post carries.
Where the grade drops away, posts are braced and connected to the beam with proper hardware so the deck does not sway.
Composite or treated boards are spaced for drainage, with joist tape where moisture lingers.
Posts that rotted where they meet the soil are cut out and replaced on new footings.
Long runs get broken up with landings, even risers and a continuous handrail.
Front porch steps, railings and column bases get rebuilt where water has done its damage.
We look at the slope, the shade and the house wall during a free on-site estimate, then send a written scope with each part of the deck priced. If an old post or ledger turns out worse once it is opened, you get a written price for the fix and decide before we do it. The village permit and inspections go on our list, not yours, and the build runs on the days we put in writing. We walk the finished deck with you top to bottom.
