Deck Repairs in Chicago
Rotted boards, loose railings, worn stair treads and popped fasteners, fixed with matched materials
The repairs that keep a sound deck safe and looking like one deck: board swaps, railing anchors, stair treads, lattice and trim. We match the wood, use the right fasteners, and finish the new material to blend with the old. If we find rot in the framing, we say so and hand it to our structural crew rather than patch over it.

What counts as a deck repair
A repair is a fix to the parts of the deck you walk on and hold: boards, railings, stair treads, lattice, trim and the fasteners that hold them. The framing underneath stays as it is. When the ledger, joists, posts or footings are the problem, that is a structural repair, and we quote it separately with the permit work it needs.
We repair with materials that match: pressure-treated #2 southern yellow pine for anything that carries weight, cedar or the deck's own species for boards, hot-dip galvanized or stainless fasteners, and Simpson connectors where a joist or post connection is involved. New boards are finished to blend with the old ones, and we tell you honestly that a new board stays lighter until it has weathered a season.
Cleaning is not a repair, and we have moved it to where it belongs. Washing, brightening and the yearly coat are part of our maintenance plans; this page is about fixing things.
Deck Problems We Repair
The everyday failures on an otherwise sound deck. Each one is a repair, not a rebuild.
Soft or Rotted Boards
One or a few spongy boards, usually where water pooled or a planter sat. Cut out, replaced with matched wood, fastened flush.
Popped Nails and Screws
Fasteners that back out with the seasons are a trip hazard and a splinter waiting to happen. We reset or replace them with the right screw.
Wobbly Railing Sections
A railing that moves when leaned on needs its posts re-anchored and its connections reinforced, not another screw through the same hole.
Worn or Cracked Stair Treads
Treads take the most wear on the deck. We replace cracked or cupped treads and tighten the stringer connections.
Broken Lattice and Skirting
Skirting that has rotted at the ground line or lattice that has come loose is replaced and set off the soil so it lasts.
Sagging Gates and Trim
Gate hinges, fascia boards and trim that have pulled away are re-hung and refastened so the deck looks finished again.
Deck Repair Services We Handle
Everything on this list is done by the same crew, in one visit for most decks.
Board Replacement
Rotted, cracked or cupped boards replaced with matched species and thickness, fastened to sit flush with their neighbours and finished to blend.
Fastener Reset
Popped nails pulled and replaced with coated screws; loose boards refastened; screw heads set below the surface so bare feet are safe.
Railing Tighten and Post Reset
Loose posts re-anchored with through-bolts or the right hardware, spindles replaced, handrails refastened so the railing takes a lean.
Stair Treads and Rails
Cracked treads replaced, stringer connections tightened, stair rails re-anchored. Rebuilding a whole stair is structural work.
Lattice, Skirting and Trim
Rotted skirting and loose lattice replaced and set clear of the ground; fascia and trim boards refastened or renewed.
Finish to Match
New boards and repairs are stained or sealed to blend with the rest of the deck. If the whole deck is due, we quote a restoration instead.
Our Repair Process: Four Careful Steps
Small jobs still get a written estimate and a walkthrough. This is how a repair visit runs.
Inspect the Whole Deck
We check every board, rail and stair, and look underneath. If the framing is the real problem, you hear it now, not after the boards are in.
Written Estimate
Each repair listed with its price. Materials named. A repair-versus-restoration recommendation if the list is getting long.
Repair With Matched Materials
Boards, fasteners, posts and treads replaced with the right material, set flush and fastened to last.
Finish and Walk Through
New wood finished to blend, fasteners checked, debris removed. We walk the deck with you and hand over the two-year warranty.
How long it takes
- Visit 1Inspection and written estimate, usually within the week you call.
- Visit 2The repairs. Most decks are done in one working day; extensive board or stair work takes two or three.
- Same dayFinish applied to new wood where the weather allows; otherwise a short return visit.
- AfterDeck usable immediately; keep furniture off freshly finished boards for 48 hours.
What Shapes a Deck Repair Quote
Repairs are quoted by the piece, so the estimate reads like a list. These are the things that move the total.
What shapes the price
- How many boards, treads or spindles need replacing. Each is its own line.
- Material match. Cedar and ipe cost more than pressure-treated pine; matching a discontinued board size takes sourcing.
- Railing work. Re-anchoring a post takes longer than tightening a rail; through-bolting a post beats a screw every time.
- Finishing. Blending new boards into an existing finish, or refinishing the whole deck if it is due.
- What we find underneath. If a board is soft because the joist under it is rotten, the job becomes structural and is quoted as such before we go further.
Our documented repair project in Chicago shows a 560 sq ft deck with new treads and refinished risers at $1,525. Every estimate is free and written; if we find something under the deck we did not quote, we stop and talk to you first.

Deck Repair FAQs
The questions Chicago homeowners ask before booking a repair.
When It Is More Than a Repair
Rot in the framing goes to our structural crew. A deck that needs a dozen boards and a new finish is usually better served by a restoration. Cleaning and the yearly coat live under maintenance.
