Deck Building London, Ontario
Custom wood and composite decks designed around how your family actually lives — built to code, square, solid and warrantied.
A deck is the hardest-working square footage on a London property — May barbecues, July evenings, Thanksgiving overflow seating. Quality deck building in London, Ontario starts long before lumber arrives: it starts with footings that reach below frost, a structure sized to real loads, and a design that fits your yard's sun, slope and sightlines. JSQ Gardens designs and builds custom decks across London and the surrounding communities, from compact landings in Old South to multi-level entertainment decks backing onto the ravines in Byron.

Wood or Composite?
Pressure-treated wood remains the budget champion and takes stain beautifully, but it asks for maintenance every two to three years in our climate. Composite costs roughly 40–70% more up front yet never needs staining, won't splinter under bare feet, and keeps its colour through London's intense summer UV and slushy winters. For families planning to stay in their home a decade or more, composite usually wins on total cost; for a starter home or rental, wood often makes more sense. We dig into the numbers in our guide to wood vs. composite decking in London.
Built for Ontario Winters
Every JSQ deck stands on concrete footings poured below the local frost line, so spring heave never racks your structure or pops your stairs out of level. We use proper joist spacing for your chosen decking (composite demands tighter centres), hidden fasteners where the product supports them, and flashing at the ledger so water never gets trapped against your home. Stairs get consistent rises, deep treads and solid stringers — the details you feel every single day.
Make It a Complete Backyard
Decks rarely live alone. Many clients pair a new deck with an interlocking patio at grade for the fire pit, a privacy fence to frame the space, or refreshed garden beds to soften the edges. Quoting these together means one crew, one timeline, and one cohesive design instead of a patchwork.
Deck Building FAQs
Do I need a permit for a deck in London, Ontario?
Decks above a certain height or attached to the house generally require a City of London building permit. We handle code-compliant design and can prepare drawings suitable for your permit application.
How long does a deck build take?
A straightforward single-level deck typically takes one to two weeks including footing cure time. Multi-level builds, custom railings or permit timelines can extend that — you'll get a realistic schedule up front.
What's the real cost difference between wood and composite?
Composite usually costs 40–70% more up front, but pressure-treated wood needs cleaning and staining every 2–3 years. Over 10–15 years the totals often converge; we'll price both for your design.
Can you replace just the deck boards on my existing frame?
If your structure is sound and built to code, yes — a re-deck with new boards and railings costs far less than a full rebuild. We inspect the frame honestly first and never re-skin a failing structure.
What time of year can you build?
April through November is prime season. Booking in late winter gets you on the spring schedule before the rush — and material pricing is often better.
