Your local Richmond Hill deck builder
Deck Master Inc. has designed and built decks for Richmond Hill homeowners for over 20 years. From an estate lot in Bayview Hill to a walkout backyard in Oak Ridges, we design and build decks that respect the grade, the trees and the character of the home. We handle the whole project in-house — design, permits, framing, decking and railings — with our own WSIB-insured crews, which is how we've earned a 3× HomeStars “Best of” record (2022, 2024, 2025), Home Depot Pro partner status and a 5.0 client rating.

Local knowledge that protects your investment
Richmond Hill homes and lots have their own quirks — grade changes, mature trees, walkouts and clay soils all affect how a deck should be framed and footed. We size footings below the frost line for Ontario's freeze-thaw cycles, plan around drainage and existing landscaping, and design to suit the architecture of the home rather than dropping in a generic rectangle. Getting these fundamentals right is what separates a deck that still feels solid in fifteen years from one that heaves or sags after a couple of hard winters.
- Deck designs matched to Richmond Hill lot sizes, slopes and home styles
- Frost-depth footings engineered for Ontario's winters
- Multi-level and walkout decks for sloped and raised properties
- Low-maintenance composite or natural cedar — your choice
Permits & approvals
Most decks more than 600 mm above grade, or attached to the house, need a building permit from the City of Richmond Hill and must respect local zoning setbacks. Deck Master prepares the drawings and manages the permit process for Richmond Hill projects so everything passes inspection and is fully code-compliant — you never have to chase paperwork with the municipality.
