- Exterior trades, one crew

- Foreman from quote to cleanup
Scope and materials
Built around the way you use it.
It starts underfoot. The decking you choose sets the look, the upkeep, and how the whole deck feels to walk on.
Set it and forget it
Composite Decks
A manufactured board that holds its colour and skips the yearly sand-and-stain, so the deck looks the same in year ten as it did on day one.
- No annual maintenance
- Consistent colour and texture
- Resists fading and splintering
The statement deck
Hardwood Decks
Dense, richly grained wood for homeowners who want the deck to be the feature of the yard, not just the floor of it.
- Deep, distinctive grain
- Naturally dense and durable
- A premium, high-end finish
From first look to final detailOur process
A process you can follow.
Three steps, one crew. You deal with the same foreman from the first walkthrough to the final sweep.
- 01
Walk the yard
We look at the grade, the access, and how you want to use the space, then talk through materials and a layout that fits the lot.
- 02
Lock the details
Decking, railing style, stair runs, and any lighting rough-in get confirmed on paper before we order material, so the quote is the price you pay.
- 03
Build it clean
One crew handles footings, framing, decking, and finish work, and the site gets swept down at the end of each day.
Details that matter
What good work looks like.
A durable deck starts with the details permit reviewers and manufacturers focus on: footings, spans, stairs, guards, fasteners, and safe excavation.
01
Deck footings and framing
Permit drawings identify footing size, depth, frost protection, and beam and joist spans. We build those structural details to the approved plan so the deck stays firm underfoot.
02
Composite installed to spec
Composite decking expands and contracts differently from wood. Joist spacing, board gaps, fasteners, and end clearances follow the selected manufacturer’s installation guide.
03
Stairs and guards built in
Stair rise and run, guard height, openings, and connections are resolved with the deck layout, not improvised after the platform is already framed.
04
Utility locates before digging
Ontario requires public utility locates before excavation. We wait for the locate responses and account for any private lines before deck footings or posts go into the ground.
05
Ledger and water management
Where a deck meets the house, structural ledger attachment and water management both matter. Flashing and drainage details are integrated so runoff does not collect against wall sheathing.
06
Care matched to the decking
Pressure-treated wood, composite, and hardwood have different cleaning and finishing needs. We explain the maintenance cycle, repairability, and manufacturer requirements before material is ordered.
In our clients’ words.
Built with us? Share your experienceThe quote we got didn't change at all, even after they pulled the old ledger board and found rot underneath. And it was the same foreman the whole way through, from the first walkthrough to the final cleanup.
We needed a fence up fast before our dog found another way out. The crew had it done in three days and the gate still swings straight, so we haven't had to call them back for anything.
They replaced our cracked driveway here in Vaughan. They sorted out the permit themselves, and even with a few rain delays they still poured when they said they would. The cleanup afterward was better than we expected too.
