Decks Built to Last Illinois Winters

Composite and cedar decks, elevated decks, pergolas and pavilions — designed, permitted and built by our own carpenters across Lake County.

What We Build

Every deck below was built by SDI crews. We handle the design, the village permit and the inspection, so you are not chasing paperwork.

Low maintenance composite in a range of colours — no staining, no splinters, and it holds up to freeze and thaw.

Classic cedar and pressure treated framing when you want real timber, built on properly footed posts.

Second-storey decks, walkouts and stepped levels that work with a sloping yard instead of fighting it.

White composite posts, black aluminium balusters, cedar handrails, cascading stairs and code-compliant guards.

Cedar pergolas, covered pavilions and privacy screens to make the deck usable in full sun.

Recessed riser and post lighting, built-in benches, planter boxes, hot tub platforms and skirting.

36 decks, porches and outdoor structures we have built across Lake County.

We come out, measure, talk through materials and layout, and give you a written price. No charge and no pressure.

We draw it, submit to your village and handle the permit. Lake County towns each want something slightly different — we know them.

Concrete footings below the frost line, then framing and joists. This is the part nobody sees and the part that decides how long it lasts.

Decking, railings, stairs, lighting and skirting, finished and cleaned up. We book the final inspection for you.
