Ask anyone who lives in Unionville why they chose it and the answer is rarely just about square footage or school ratings. It’s about Main Street on a summer evening. It’s about Toogood Pond in the morning. It’s about a community that feels like a place, not just a postal code — one that has held onto its heritage character through decades of development pressure on every side. People who choose Unionville are people who care about how things look and how they feel, not just what they cost.
That matters enormously when it comes to building a deck. Deck builders in Unionville are working in a community where the aesthetic standard is set by heritage storefronts, mature tree canopies, and homes that people have invested in deeply — not just financially but personally. A deck that looks like it was ordered from a catalogue and installed in an afternoon doesn’t belong here. A deck that was designed for the property, built with care, and chosen for materials that age well in the Ontario climate absolutely does.
Captain Handy builds custom decks across Unionville and the broader Markham area. We design and construct outdoor living spaces that respect the architectural character of the home they’re attached to, work within the specific constraints of the lot, and hold up through everything an Ontario winter and summer can deliver. If you’ve been searching for deck builders near me and want a contractor who treats your Unionville property as carefully as you do, this is the right starting point.
Why Deck Building in Unionville Deserves Careful Thinking
Unionville isn’t a one-size-fits-all community. You have heritage homes on and near Main Street with specific architectural character and, in some cases, heritage overlay considerations that affect what can be built and how. You have established suburban developments from the 1980s and 1990s with mature lots and traditional home styles. And you have newer builds in the surrounding Markham communities that lean contemporary. Deck building in Unionville means understanding which context you’re working in — and making decisions accordingly.
It also means understanding the City of Markham’s building department process, which governs permits across Unionville. Markham takes residential construction compliance seriously, and a deck contractor in Unionville who doesn’t know the local process adds weeks and frustration to a project that should run smoothly.
Captain Handy has worked across Markham long enough to know the permit timelines, the documentation requirements, and the inspection process. We handle all of it, which means you focus on choosing what you want — not navigating city bureaucracy.
Heritage Character and How It Shapes Deck Design
For homes in and around Unionville’s heritage core, a deck project involves an additional layer of design consideration: how does the new structure relate to the existing architecture? A modern glass-and-cable railing system on a Victorian-era home often fights with the building rather than complementing it. A cedar deck with period-appropriate trim and railing profiles, on the other hand, looks like it was always there.
This isn’t just aesthetics. In heritage-sensitive areas, the City of Markham may have specific requirements around what materials and profiles are appropriate for visible additions to designated or heritage-adjacent properties. Captain Handy approaches every custom deck design in Unionville with the home’s architectural context as the starting point — so the result enhances the property rather than working against it.
Deck Materials Built for Unionville Properties and Ontario Weather
Choosing the right material is where the long-term success of any deck is determined. In Unionville, that conversation involves Ontario’s freeze-thaw climate, the specific character of the lot and home, and how much ongoing maintenance the homeowner wants to carry. Here is an honest guide to every material we work with.
Cedar Deck: The Heritage-Appropriate Natural Choice
Cedar decking is the natural first conversation for heritage-character homes in Unionville. It’s a traditional material with a warmth and grain that genuinely complements older architectural styles — Victorian, Edwardian, and the traditional colonial designs common throughout established Markham neighbourhoods. Cedar is naturally resistant to rot and insects without chemical treatment, which matters on lots with significant tree cover and higher ambient moisture from mature landscaping.
A cedar deck installed by Captain Handy isn’t off-the-shelf cedar. We source tight-grain, kiln-dried lumber, build with hidden fasteners for a clean finished surface, and specify a finish suited to the local sun and moisture exposure. Properly maintained, cedar decking ages beautifully over 20 to 30 years — developing the kind of character that suits a Unionville property.
Composite Decking: The Practical Long-Term Choice
Composite decking is where most Unionville homeowners end up when they think carefully about the full cost of ownership. Premium composite brands — Trex, Fiberon, TimberTech, Azek, TruNorth — deliver the appearance of natural wood with none of the annual maintenance commitment. No staining, no sealing, no sanding splintered edges in spring. Just a consistently good-looking surface through every Ontario season for 25 to 30 years.
Composite deck cost in Unionville runs higher upfront than pressure-treated lumber or cedar — typically $60 to $95 per square foot installed depending on brand and project scope. But when you remove every maintenance cost from the equation over three decades, the investment makes straightforward financial sense. A trex deck in Unionville carries a 25-year fade and stain warranty. For a family that wants outdoor space they enjoy rather than outdoor space they maintain, composite is the professional recommendation.
Pressure Treated Deck: Honest Value, Properly Built
A pressure treated deck is the most cost-accessible starting point for a Unionville project, and when it’s built correctly, it’s a legitimate long-term choice. Pressure-treated lumber is chemically rated to resist rot, moisture, and insects, and a PT deck built with proper fasteners, correct board spacing, and adequate substructure ventilation will perform reliably for 20 years.
The critical variable is the build quality. Pressure-treated decks that underperform — and many do — fail because of under-specified framing, wrong fastener choice, or inadequate ventilation causing moisture accumulation under the boards. Captain Handy builds every pressure treated deck in Unionville to the structural standard it deserves, regardless of price point.
PVC Decking: When Moisture Is a Primary Factor
PVC decking is 100% synthetic — no wood content — which makes it completely waterproof in every direction. For pool deck applications, shaded lots with high moisture, or elevated deck structures where drainage is constrained, PVC eliminates moisture as a failure variable entirely. It won’t swell, won’t absorb, and won’t degrade regardless of what Ontario weather delivers. As a dedicated pool deck builder in Unionville, Captain Handy specifies PVC for most poolside applications where longevity and slip resistance are the primary requirements.
IPE Deck: The Premium Hardwood Option
An IPE deck is a long-term investment in the most literal sense. This South American hardwood resists rot, insects, fire, and UV damage without any chemical treatment, and carries a documented lifespan of 40 to 75 years. For Unionville homeowners building a premium outdoor space and making a once-in-a-generation material choice, IPE delivers a quality and longevity that nothing else in the deck materials category matches.
Every Type of Deck We Build in Unionville
Backyard Deck: The Heart of Family Outdoor Living
In Unionville, a backyard deck is where summer actually happens. It’s where the family eats from May to October, where the kids come back to from the garden, where neighbours are entertained on weekend afternoons. A backyard deck in Unionville needs to work hard: enough space for a table and chairs and still room to move, surfaces that hold up to kids and wet feet and years of use, and a design that feels right against the back of the house it’s attached to.
Captain Handy designs every backyard deck in Unionville around how the family actually uses the space — not a generic layout. We generate a 3D deck design before construction begins so you can see the scale, the flow, and the relationship to the house and garden before a single board is installed.
Elevated Deck: Making Grade Changes Work for You
Unionville’s established lots frequently have meaningful grade changes — a rear yard that drops away from the house, or a foundation height that puts the back door above natural grade. An elevated deck turns those conditions into an opportunity: a raised platform with improved views, better air circulation, and a visual presence that a ground-level structure simply can’t achieve.
Captain Handy engineers elevated deck structures with footings below the Ontario frost line, correct beam and joist sizing for the span, and post connections that meet Markham building code requirements. The structure underneath an elevated deck is as important as the surface on top of it — and we build both with the same standard of care.
Pool Deck: Built for Ontario Summers
A pool deck is one of the most demanding environments in residential construction: constant water exposure, UV intensity, heavy barefoot traffic, and pool chemistry contact. As an experienced pool deck builder in Unionville, Captain Handy designs pool surrounds with all of it in mind — composite or PVC decking rated for poolside conditions, proper drainage slopes, slip-resistant surface texture, and a finished appearance that integrates cleanly with the pool coping and surrounding landscape.
Rooftop Deck: Capturing Space You Didn’t Know You Had
On properties with flat-roofed garages or rear additions, a rooftop deck in Unionville is an option that many homeowners overlook entirely. A properly designed rooftop deck creates a private outdoor living platform above the garden — open sky, elevated views, and a level of privacy from neighbours that ground-level decks can’t offer on a suburban lot. These projects require waterproofing expertise, structural load assessment, and proper drainage engineering. Captain Handy manages the complete scope including the City of Markham permit process.
Deck Renovation: Bringing an Existing Deck Up to Standard
Many Unionville homes have decks that were built 15 to 25 years ago and are showing their age. Deck renovation in Unionville is often the most cost-efficient path to an outdoor space you’re genuinely proud of: replacing the decking surface and railings on a structurally sound frame can deliver a result that looks and performs like a new deck at 40 to 60% of a full rebuild cost.
Captain Handy always starts a deck renovation with a structural assessment. If the frame is solid, we renovate. If it isn’t, we’re honest about it and propose a rebuild that’s priced and scoped fairly. The goal is the right outcome for the property, not the quickest sale.
Deck Permits in Unionville: Handled From Start to Finish
Building permits for decks in Unionville fall under the City of Markham’s building department, operating under Ontario’s Building Code. Most residential decks require a permit — any deck attached to the house, any structure elevated more than 600mm above grade, and most projects above a minimum footprint threshold.
A deck permit in Unionville is not optional paperwork. Building without one creates real exposure: stop-work orders, compliance orders, and significant problems at the time of sale when an unpermitted structure has to be disclosed. Heritage-adjacent properties carry additional considerations around design compliance that make the permit process even more important to manage correctly.
Captain Handy handles the deck permit in Unionville from first drawing to final inspection. We prepare the documentation, submit to Markham’s building department, coordinate inspections at each required stage, and deliver a fully compliant, fully documented structure. You don’t need to learn the permit process — that’s our job.
What Does Deck Installation in Unionville Cost?
Deck cost in Unionville depends on materials, size, and project complexity. Here is a current, honest breakdown of installed costs:
- Pressure treated deck: $35–55 per sq ft installed
- Cedar deck: $45–70 per sq ft installed
- Composite decking: $60–95 per sq ft installed
- PVC decking: $70–100 per sq ft installed
- IPE deck: $90–130 per sq ft installed
Installed costs include framing, decking boards, standard railings, and permit coordination. Elevated structures, glass or cable railing systems, built-in lighting, privacy screens, or pool deck integration add to the total and to what the finished space delivers.

FAQs About Deck Builders in Unionville
Do heritage homes in Unionville have special rules for deck construction?
Properties within or adjacent to Unionville’s heritage conservation district may be subject to additional design requirements under the City of Markham’s heritage guidelines. This can affect the materials, profiles, and visual character of additions including decks — particularly for structures visible from the street or affecting the heritage facade. A licensed deck contractor familiar with Markham’s building department will identify any heritage considerations during the design phase and ensure the project meets all applicable requirements before submission.
What decking material requires the least maintenance in Ontario?
PVC decking is the zero-maintenance leader — completely synthetic, waterproof, and requiring only occasional cleaning. Premium composite decking from brands like Trex, Fiberon, or TimberTech is a close second and the most popular choice overall, requiring no staining, sealing, or sanding and carrying warranties of 25 to 50 years. Both outperform natural wood significantly in the Ontario climate in terms of maintenance obligation over the life of the deck.
How do I know if my existing deck needs renovation or a full rebuild?
The decision comes down to the condition of the substructure. If the posts, beams, joists, and footings are structurally sound and meet current code requirements, a renovation — replacing the decking boards, railings, and hardware — is typically 40 to 60% of a full rebuild cost and delivers an essentially new result. If the framing is rotted, undersized, or non-compliant, a rebuild is the responsible recommendation. A proper structural assessment from a licensed contractor is the only reliable way to determine which path is right for your specific deck.
How long does the permit process take in Markham?
The City of Markham’s building permit process for a standard residential deck typically takes 3 to 5 weeks from a complete submission to approval. More complex projects — elevated decks, rooftop applications, or projects requiring structural engineering — can take longer. Submitting early in the year, before the spring construction rush, gives you the best chance of an approval timeline that doesn’t delay your build date. Captain Handy submits the permit application at the project outset so the timing works in your favour.
Is a pool deck different from a regular backyard deck?
Yes, in several important ways. Pool decks are exposed to constant moisture, pool chemistry, intense UV, and heavy barefoot traffic — conditions that exceed what a standard backyard deck encounters. Material selection, drainage slope, slip-resistance rating, and hardware specification all need to be appropriate for poolside use. Composite and PVC are the professional recommendation for pool surrounds in Ontario because they handle moisture and chemical exposure without warping, staining, or degrading over time the way natural wood does.
