Newmarket Deck Contractors — Custom Decks Since 1984
Designing and building custom decks for Newmarket homeowners since 1984. We’re a Trex Pro Platinum installer based on Yonge Street in Richmond Hill — a short drive south — so we’re on your Newmarket property fast, from the established homes in Old Newmarket and Bristol-London to the newer builds in Stonehaven, Glenway, Woodland Hill, and Summerhill.
Serving Newmarket & Nearby Communities
We build decks across the area, including Aurora, Richmond Hill, King City, and Bradford.
Decks Built for Newmarket Homes
Newmarket backyards vary widely. The mature lots in Old Newmarket and around Fairy Lake come with established trees and grade changes; the newer subdivisions in Stonehaven and Woodland Hill bring walk-out basements and tighter setbacks. We design each deck around your lot and how you actually use your yard — not from a stock plan.
We design and build:
- Multi-level and wraparound decks for sloped and split-grade lots
- Raised and walk-out basement decks
- Composite, PVC, and cedar decks
- Poolside decks, deck replacements, and extensions
- Integrated railings, privacy screens, lighting, and built-in seating

Composite, PVC, or Cedar? Built for Newmarket's Climate
Newmarket winters are hard on decks — freeze-thaw cycles crack and warp wood, and months of snow load keep surfaces wet. The material you choose decides how much maintenance you’ll do and how long the deck lasts. As a Trex Pro Platinum installer — Trex’s highest certification, held by a small share of contractors — we build in low-maintenance composite as well as traditional cedar and PVC, and match the material to your budget and how you use the space.

Building a Deck in Newmarket: Permits & Zoning
We handle the Town of Newmarket permit process for you — here’s what homeowners should know.
Do I need a permit to build a deck in Newmarket? Generally yes if the deck is more than 600 mm (about 24 inches) above grade or larger than about 10 m² (100 sq ft); a guard is required once a deck is more than 2 feet above grade. Lower, smaller freestanding decks may not need a permit — but still must meet zoning.
There’s a zoning step before the permit — we handle it. Newmarket requires a Zoning Preliminary Review before you submit the building permit application (its fee is credited toward the permit). It confirms your deck meets setbacks and lot coverage for your property’s zone before drawings go in — a step homeowners often miss. We manage it for you.
What are the setback and zoning rules? They depend on your property’s specific zone. We confirm your zoning using the Town’s “What’s My Zoning” / Navigate Newmarket tool before we design, so the deck fits the rules the first time.
