Repairs, Resurfacing, Staining and Railing Fixes
We repair decks across Newmarket, Aurora, Richmond Hill, Vaughan and cottage country: rotted boards, loose or wobbly railings, sagging frames, failed stairs and worn finishes. If the frame is sound we fix it. If it is not, we tell you before you spend money on a deck that needs replacing.

A Deck Repair Company That Checks the Frame Before Selling You Boards
Most deck repair calls start with a symptom: a soft board, a railing that moves, stairs that bounce. The board is rarely the problem. Water gets in at the ledger, the post bases or the joist tops, and by the time a board goes soft the framing under it has usually been wet for years. So every repair starts underneath.
We open up the deck, probe the joists and beams, check the ledger connection and the footings, and only then quote. A deck with a solid frame gets new boards, hardware and a finish and goes on for another decade. A deck with a rotten frame gets an honest recommendation for [deck replacement](/deck-replacement-and-removal/), because resurfacing a failing frame wastes your money.
Deck Repair Services We Offer
From a single rotted board to a full resurfacing, these are the deck repairs we handle most across York Region and cottage country.
Board and Surface Repair
Replacing cracked, split or rotted boards, and full deck resurfacing when the frame is sound but the surface is done. Pressure-treated, cedar or an upgrade to composite boards on the existing frame.
Railing and Stair Repair
Wobbly posts, loose balusters, rotted stair stringers and guards that no longer meet the Ontario Building Code. We re-anchor, replace and bring them back to code height and spacing.
Structural Repair
Sistering rotted joists, replacing beams, re-supporting a sagging frame and correcting ledger boards that were fastened to brick veneer or without flashing.
Footing and Post Repair
Posts that have heaved, sunk or rotted at grade. We replace post bases with standoff brackets, pour new footings below the frost line where needed, and level the frame.
Deck Staining and Refinishing
Cleaning, sanding and staining or sealing wood decks, and refinishing weathered cedar and pressure-treated surfaces so they shed water again.
Deck Maintenance and Inspection
A once-over before the season: fasteners, flashing, ledger, guards and footings, with a written list of what needs attention now and what can wait.
What We Use for Deck Repairs
Repairs only last if the replacement parts are rated for the job. These are the materials we bring to a repair.
Ground-Rated Pressure-Treated Lumber
Joists, beams and posts are replaced with ground-contact rated lumber, never deck-grade boards, and every cut end is treated before it goes in.
Joist Tape and Flashing
Every joist top and ledger gets a self-adhesive membrane so the next fastener hole does not become the next rot pocket.
Composite Boards on a Sound Frame
When the frame passes inspection, swapping wood boards for composite is the repair that ends the annual staining. See our [composite decking](/deck-materials/composite-decking/) page for the brands we install.
Railing repairs use aluminum, glass or wood systems matched to what is already there, with hardware rated for outdoor use. Stains and sealers are chosen for the wood species and its exposure.
When a Deck Repair Needs a Permit
Like-for-like repairs usually do not need a permit. Structural changes usually do. This is how the towns we work in draw the line.
Repair permits, at a glance
- Replacing boards or a finish
- No permit when the structure is unchanged. Resurfacing a sound frame with new boards is maintenance.
- Replacing railings
- No permit for like-for-like, but the new guard must meet the current Ontario Building Code: 36 in above grade up to 1.8 m, 42 in above that, openings under 100 mm.
- Sistering or replacing joists
- Usually no permit if spans and loads do not change. We confirm with the town when a beam or post is replaced.
- New footings or posts
- Permit in most towns. Richmond Hill and King Township require one for any deck work that touches the structure.
- Enlarging or raising the deck
- Permit. Any change to size, height or attachment is treated as new construction.
- Decks near water or ravines
- Conservation authority sign-off (LSRCA, TRCA or Kawartha Conservation) may apply before the town issues a permit.
We tell you at the quote which category your repair falls into and file the permit where one is needed.
How We Repair a Deck, Start to Finish
Step 1
Inspection
We probe joists, beams, posts and the ledger, check the footings and guards, and photograph what we find.
Step 2
Repair or replace
You get a written verdict: what can be repaired, what should be replaced, and what each costs.
Step 3
Frame first
Rotted framing is cut out and replaced, joists are taped, post bases and footings corrected.
Step 4
Surface and guards
New boards, stairs and railings go on, fastened and spaced to code.
Step 5
Finish and walkthrough
Stain or seal where the wood needs it, then a walkthrough with you and a note on when to check it next.

What Affects the Cost of a Deck Repair
Small repairs are quoted by the job, larger ones by what the inspection finds. These are the things that move the price.
How much surface is affected
A few boards is a half-day. A full resurfacing is priced like a small build.
What the frame looks like underneath
Sistering two joists is cheap. Replacing a beam or the ledger is not.
Railings and stairs
Re-anchoring posts is minor. Replacing a whole guard to reach code height costs more.
Footings and access
New footings mean digging below the frost line, and tight access adds labour.
Staining and finishing
Cleaning, sanding and staining is priced by square footage and the wood's condition.

Book a Deck InspectionFrequently Asked Questions
Repair it if the frame, posts and ledger are sound and the problems are on the surface: boards, railings, stairs or finish. Replace it if joists or beams are rotted through, posts have heaved, or the ledger was never flashed. We inspect first and give you a written recommendation either way.
Small repairs such as a few boards or re-anchoring a railing typically run a few hundred to around $1,500. Structural repairs, full resurfacing and new railings run higher and are quoted after inspection. We give itemized quotes so you can see what each part costs.
Yes, when the rot is limited. We cut out and sister rotted joists, replace posts and bases, and tape the frame before new boards go on. If rot has reached most of the frame, replacement is the better use of your money and we will say so.
Yes. Wobbly railings are usually a post-to-frame connection problem. We re-anchor posts through the rim joist with rated hardware and bring the guard up to the Ontario Building Code height and spacing.
Yes. We clean, sand and stain or seal wood decks, and refinish weathered cedar and pressure-treated surfaces. New pressure-treated lumber needs 30 to 60 days to dry before staining.
Not for like-for-like repairs such as boards, finishes or replacing a railing to the same design. Structural changes, new footings, or enlarging or raising the deck need a permit, and Richmond Hill and King Township require one for any structural work. We confirm with your town.
Newmarket, Aurora, Richmond Hill, Vaughan, King City, Nobleton, Keswick and Bradford, plus Kawartha Lakes and Muskoka, where repairs are booked as full days on site.
Yes, if the frame is sound and the joists are at 16 inches on centre. Resurfacing with composite on a good frame costs a fraction of a rebuild and ends the staining cycle.
