Deck Repair & Replacement in the GTA

An old deck rarely fails all at once. Boards soften, a railing starts to move, the stairs feel loose, and one day the whole deck feels less solid than it used to. Royal Decks and Landscapes repairs and replaces decks across Toronto, Mississauga, Oakville, Burlington and Brampton, and we have been building decks in the GTA since 2005.

As deck repair contractors, we start every job with the frame. If the structure is sound, we repair what is worn and keep what is worth keeping. If it is not, we tell you plainly and price a replacement, so you only pay to fix your deck once.

Signs Your Deck Needs Repair

• Soft, cracked or rotting boards
• A railing that moves when you lean on it
• A floor that bounces or slopes
• Loose, cracked or uneven stairs
• Posts sitting in soil, or footings that have heaved or settled
• Rusted hangers and screws, or a ledger board with no flashing against the house

Some of these are cosmetic. Others, like a loose railing or a rotting ledger, are safety problems that should not wait until spring.

Deck Repair Services

• Board replacement and spot repairs
• Railing repairs, or new aluminum, glass or composite railings
• Stair rebuilds and new landings
• Joist, beam and post repairs
• New footings, including helical piles where digging is difficult
• Ledger repairs and proper flashing at the house

A repair is often the right moment to improve the deck. While the old boards are off, it is easy to add a step, widen a landing or switch to low-maintenance composite.

Deck Replacement

When the frame is rotten, undersized or was never built to code, patching it is money spent twice. A deck replacement takes the old deck down to the ground and rebuilds it properly: new footings or piles, a new pressure-treated frame with joist protection tape, and composite, PVC or wood decking with railings that meet today’s code.

A replacement is also a chance to fix what never worked: stairs in the wrong place, a deck too small for a dining table, or one level where two would suit the yard better. We design the new deck before the old one comes down, and you can see it in 3D first. See our custom decks for what a rebuilt deck can look like.

New Boards on Your Existing Frame

If the frame passes inspection, resurfacing is often the best value. We remove the old boards and railings and install composite or PVC decking on the existing structure. These boards usually need joists closer together than older wood decks, so we check the spacing and add joists or blocking where needed before a single board goes down.

Permits for Deck Repairs and Replacements

Replacing boards or railings on a sound frame usually does not need a building permit. New footings, a new frame, or a deck more than 60 cm (24 inches) above the ground usually does. We check with your city for each job and prepare the drawings and the permit application for you.

Deck Repair and Replacement FAQ

Should I repair or replace my deck?

It depends on the frame. If the joists, beams, posts and footings are sound, repairs or new boards on the existing frame usually make sense. If the structure is rotten or was built below code, a replacement costs less over time than repeated repairs.

How long does a deck last before it needs replacing?

A pressure-treated wood deck often needs major repairs after 15 to 20 years, sooner if it was poorly built or stays damp in the shade. Composite and PVC boards last longer, but they are only as good as the frame under them.

Can you put composite boards on my old wood frame?

Often, yes. We check the frame and the joist spacing first, and reinforce it where needed so the new boards stay flat and keep their manufacturer warranty.

Can you fix just the railing or the stairs?

Yes. Many repairs start with one problem, like a loose railing or worn stairs. We look over the whole deck while we are there, so you know whether anything else needs attention.

Do I need a permit to replace my deck?

Usually, if the work includes new footings or framing, or the deck is more than 60 cm (24 inches) above the ground. Replacing boards and railings on a sound frame usually does not need one. We confirm the rules with your city and handle the permit.
