What does deck building cost in Newmarket? A pressure treated deck in Newmarket runs about $45 to $75 per square foot, cedar decking runs $58 to $92 per square foot, and composite decking or PVC decking runs $75 to $128 per square foot, depending on layout, railings and site access. A standard 300 sq ft backyard deck typically lands between $18,000 and $34,000 fully installed. Older properties near the Main Street heritage core sometimes carry extra site-prep costs, which we account for during the free quote.
Who best deck builders in Newmarket? Captain Handy is a licensed, insured deck contractor serving Newmarket homeowners across both the town’s historic streets and its newer east-end subdivisions. We install pressure treated, cedar, composite and PVC decking (Trex, Fiberon, TimberTech) in every configuration — backyard decks, elevated decks, rooftop decks and pool deck builds — with most Newmarket deck installation projects wrapping up in 1 to 4 weeks.
Old Newmarket vs. New Newmarket
Newmarket has two distinct personalities, and they call for different approaches to deck design. Close to Main Street and Fairy Lake, lots tend to be older, narrower and sometimes shaded by mature trees that limit where a deck can sit. Head east toward the newer subdivisions and you get bigger, flatter backyards on more recently graded lots — better suited to larger custom deck design layouts with room for a pergola or built-in seating. As deck builders near me, we design around whichever version of Newmarket your property sits in, not a one-size template.
Why Homeowners Choose Captain Handy in Newmarket
We’re a licensed, WSIB-insured deck contractor that gives every Newmarket homeowner the same process: an on-site visit, a 3D deck design walkthrough, a fixed written estimate, and a schedule we actually hit. There’s no vague “allowance” pricing that grows once the crew shows up. We also cover the towns that border Newmarket — Aurora, East Gwillimbury and the rest of York Region — so a property just outside town limits is never a problem.
Decking Materials for Newmarket Homes
Pressure treated deck lumber is still the most common starting point in Newmarket, especially for straightforward backyard deck rebuilds — it’s affordable and performs well when properly maintained. Cedar decking is the natural upgrade: warmer tone, better rot resistance, and a good visual match for the wood-frame character found around Newmarket’s older neighbourhoods.
Composite decking and PVC decking (Trex, Fiberon, TimberTech) are the move for homeowners who don’t want to sand or restrain every couple of years — they hold up through Ontario’s freeze-thaw winters with minimal upkeep and typically last 25 years or more. For larger Fairy Lake-adjacent or east-end estate properties, an ipe deck or a premium trex deck delivers a denser, longer-lasting finish that suits a bigger build.
Backyard, Elevated, Rooftop and Pool Decks
Most Newmarket projects are a standard backyard deck connecting the house to the yard, but grade changes near the older parts of town — especially close to Fairy Lake — often push us toward an elevated deck instead, with engineered footings for the slope. Rooftop deck requests are less common here than in denser parts of the GTA but do come up on newer builds. And for the in-ground pools common in Newmarket’s east-end subdivisions, a pool deck builder needs a slip-resistant, well-drained surface — composite decking and PVC decking are what we typically spec around pool edges.
Designing Before You Build
Every custom deck design at Captain Handy starts with 3D deck design software, not guesswork. You’ll see material and railing options, plus a realistic layout, before we order a single piece of composite decking or cedar. For homes near Newmarket’s historic core, this also helps confirm the design will sit comfortably with the streetscape before permit submission.
Deck Permits Through the Town of Newmarket
A deck permit is required for most new deck construction in Newmarket, issued through the Town of Newmarket’s building department. Requirements shift based on deck height, whether it’s attached to the house, and proximity to property lines — older, narrower lots near Main Street sometimes need extra setback review. Captain Handy prepares the drawings and manages the deck permit process so you’re not chasing paperwork yourself.
Replacing or Restoring an Existing Deck
Deck renovation is a regular part of our Newmarket workload, especially in the town’s older neighbourhoods where original pressure treated decks are now 20-plus years old. Soft boards, wobbly railings and undersized footings are the usual culprits. We’ll tell you plainly whether a renovation gets the job done or whether the structure is due for a full rebuild — we’re not in the business of upselling work you don’t need.

FAQs About Deck Builders in Newmarket
How much does it cost to build a deck in Newmarket?
Most Newmarket deck projects run between $18,000 and $34,000 for a standard 300 sq ft backyard deck, depending on material. Pressure treated construction sits at the lower end of that range, with composite deck cost and PVC decking at the higher end. Captain Handy provides a fixed written quote after a site visit.
Do I need a permit to build a deck in Newmarket?
Yes, most new decks require a permit issued through the Town of Newmarket, and older lots near the Main Street heritage area may need additional setback review. Captain Handy handles the drawings and permit submission as part of the project.
What’s the best decking material for Newmarket winters?
Composite decking and PVC decking handle freeze-thaw cycles with the least maintenance, while cedar decking offers a natural look that needs occasional resealing. Pressure treated wood is the most budget-friendly option but requires more regular upkeep.
How long does it take to build a deck in Newmarket?
A standard backyard deck usually takes 1 to 4 weeks from approved design to completion. Older lots near Main Street or Fairy Lake can take a bit longer if extra site prep or setback review is needed, and we’ll give you a realistic timeline before work starts.
