Deck Builder in St. Thomas & London, Ontario

Custom deck builds in pressure-treated wood or composite decking, with footings set below the frost line and railings, stairs, and lighting handled as part of one job.

Deck and fence footings before the ground freezes

Deck footings and fence posts need to go below the frost line, which means digging into unfrozen ground. Once the ground freezes, that work stops until spring. If you want a deck or fence built this year, the window to get on the schedule is now, not once the frost is already in the ground.

What's included

Every deck build includes

  • Full design and scope walkthrough before any building starts
  • Footings set below the frost line for a structure that won't heave
  • Pressure-treated or composite decking, built to current code
  • Railings, stairs, and lighting handled as part of one job
  • Final walkthrough before we call it done

Composite or pressure-treated decking?

Pressure-treated lumber costs less to install and is the more common choice in this region. It needs periodic staining or sealing to hold up well, and boards can warp, splinter, or grey over time if that maintenance gets skipped.

Composite decking costs more upfront but doesn't need staining or sealing, resists fading and splintering, and typically comes with a longer manufacturer warranty. For homeowners who want to build once and not think about the deck again for years, composite is usually the better long-term value even at the higher install cost.

We build both, so there's no incentive on our end to steer you toward the pricier option. We'll walk through the real tradeoffs for your project, budget, and how much upkeep you want to take on, during the estimate visit.

Pricing

What affects the cost of a deck installation

Every quote is different. These are the factors that move the number most.

Size and shape

Square footage matters, but so does shape, a simple rectangle costs less per square foot than a deck with multiple levels or angles.

Decking material

Pressure-treated wood costs less upfront than composite decking, which costs more to install but needs less ongoing maintenance.

Height and stairs

A deck close to grade is simpler than a raised deck needing stairs, railings, and additional structural support.

Footings and ground conditions

Rocky or difficult ground takes longer to dig footings in than clear, easy soil.

Railings and features

Built-in benches, privacy screens, and railing style all add material and labour beyond the deck surface itself.

Removal of an existing deck

Tearing out and disposing of an old deck adds work that a new build on a clear site doesn't.

We don't quote decks over the phone, ground conditions and design details need to be seen on site. The estimate visit is free and you get the number in writing with no obligation.

Yes, on every deck build, so the structure moves with the ground instead of heaving over winter.
