Keep the trees and still get a solid deck in Palos Park, laid out around the trunks and roots and framed to stand up to wet leaves.
A deck built low to the ground lives a harder life than one up on posts: it stays damp, collects leaves underneath and gets little air. We frame those decks with lumber rated for ground contact, leave room for water to drain and air to move, and keep the decking off the soil. Taller decks get footings below frost, posts tied to the beams and a ledger at the house that is flashed and bolted. In either case, the stairs and railings go in to current code.
We cover Palos Park by way of Route 45, 123rd Street and McCarthy Road, with the Palos and Sag Valley forest preserves close by. It is a Cook County village near Palos Heights and Orland Park. If your yard has mature trees, we lay out the deck so footings miss the big roots and leave a gap around any trunk the deck wraps, so the tree can grow without lifting the boards. Leaves that settle between boards hold water, so board spacing and a cleanable underside matter.

Framing wraps a trunk with room to grow, and footings are placed to miss the main roots.
Ground-contact framing, drainage under the deck and enough clearance let air move underneath.
Soft framing is cut out and replaced or sistered so the deck is solid again.
A ledger without flashing or bolts gets corrected before anything new goes on.
Risers are even, long runs get landings, and railings sit at the right height with tight baluster spacing.
Rotted column bases and porch treads are rebuilt and left ready for paint.
We start in the yard, looking at the trees, the grade and the underside of any existing deck, and the estimate is free. You get a written scope with the layout, materials and permit on it. If the old frame hides more rot than we could see, the added work is priced in writing and waits on your approval. We line up the permit and inspections, work on the dates we gave you and walk the finished deck with you.
The trees can stay. Call or text (815) 585-1750 and we will plan your Palos Park deck around them.
