Carpenters who finish what they said they would, when they said they would.
Lake Ontario Contracting started as a deck sanding and staining operation in high school. A decade-plus later, we build custom decks, pergolas, fences, interior work, and refinishing across the Lake Ontario corridor — from Oakville to Burlington, Mississauga to Toronto. Craftsmanship, honest timelines, no corners cut.
We respond to inbound within one business day — usually same day.
Carpentry built to last through the Great Lakes freeze-thaw.
Four of our most-requested outdoor-living specialties below — plus interior work, drywall, flooring, trim, and glass + door installation. Everything on one invoice, one crew, one point of contact.
Custom DecksNew builds, walkouts, multi-level, cedar + composite — built for Ontario winters.
From a backyard walkout to a wrap-around multi-level — code-compliant framing, your choice of cedar / pressure-treated / composite, permit handled where required.
Deck RefinishingSanding, staining + sealing — bring an aging deck back to new.
Full strip, sand smooth, re-stain and seal — the right stain system for your species, properly prepped so it actually lasts through a Great Lakes winter.
PergolasFreestanding + attached — cedar, aluminum, with privacy walls on request.
Freestanding or attached to the house. Cedar, pressure-treated, or aluminum. Beam-and-rafter traditional or slatted modern. Built on footings that survive the thaw.
FencesWood, cedar, horizontal-plank — properly posted so they outlast the warranty.
Pressure-treated board-on-board, cedar privacy, horizontal-plank modern, aluminum ornamental. Posts set below frost line so they don't heave the first winter.
