Yeah, composite decks and PVC decks are nice. But they cost 2-3 times more upfront. A lot of homeowners in Toronto & GTA would rather put that extra $15,000 into landscaping or a backyard kitchen. Makes sense to us.
Here’s what you actually get with a quality pressure treated deck built by our team:
✔ Most affordable decking option – real savings compared to composite or PVC
✔ Natural wood look and feel that many homeowners love
✔ Can be stained any color you want – change it up every few years if you like
✔ MicroPro Sienna lumber comes with manufacturer Warranty against rot and termites
✔ Easy to repair – just replace a board or two if needed
✔ Built to handle Toronto’s freeze-thaw cycles when installed properly
✔ 2-year labor warranty from Decksforlife on every installation
One family in Vaughan told us they were quoted $38,000 for a composite deck. We built them a beautiful pressure treated deck with MicroPro Sienna lumber for $18,000. They used the savings to add a pergola and privacy screen. Smart choice.
Not all pressure treated wood is the same. That greenish lumber you see at big box stores? It works, but it doesn’t look great and takes months to dry out before you can stain it.
We use MicroPro Sienna exclusively on our pressure treated deck projects. Here’s why:
Better Looking Right Away
MicroPro Sienna has a warm brown tone straight from the lumber yard. It looks more like cedar than traditional pressure treated wood. Your deck will look better on day one, and you don’t have to wait months before staining.
Eco-Friendly Treatment Process
The MicroPro process uses micronized copper azole (MCA) instead of older chemical treatments. It’s certified as an Environmentally Preferable Product and has UL GREENGUARD Gold certification for low VOCs. If you’ve got kids running around barefoot on the deck, this matters.
Less Corrosive to Hardware
Older pressure treated wood was tough on metal fasteners and connectors. MicroPro Sienna is no more corrosive than untreated wood, which means your deck hardware lasts longer and your structure stays solid.
Manufacturer Warranty Protection
MicroPro Sienna products are backed by a Manufacturer Limited Residential Warranty against structural failure from fungal decay or termites. That’s real peace of mind for homeowners in Toronto where we deal with moisture and humidity all summer long.
We’re a local deck company based right here in the GTA, and we service the entire Toronto area. Whether you’re in a North York townhouse, an Oakville detached home, or a Markham property with a pool, we’ve probably worked on a similar project nearby.
Some of the areas where we build pressure treated decks regularly:

✔ Mississauga: Port Credit, Streetsville, Meadowvale, Erin Mills
✔ Brampton: All neighborhoods
✔ Vaughan: Woodbridge, Thornhill, Maple
✔ Richmond Hill & Markham: Full coverage

Every area has its own building codes and permit requirements. We handle all that paperwork for you because honestly, dealing with Toronto building permits is not fun.
Our Recent Pressure Treated Deck Projects
This is the question everyone wants answered upfront. And we get it. You need to know if a pressure treated deck fits your budget before wasting time on consultations.
Here’s what pressure treated deck installation actually costs in Toronto right now:

- Materials only: $17 – $25 per square foot
- Installed (complete project): $30 – $50 per square foot
Complete Project Pricing
| Deck Size | Price Range (Installed) |

What Affects Your Price
Deck Height: Ground-level decks are cheapest. Second-story walkouts can add $5,000 – $15,000 for the extra structural work and stairs.
Deck Shape: Simple rectangles use materials most efficiently. L-shapes add 10-15%. Multi-level designs add 25-40%.
Railings: Pressure treated wood railings are most affordable at $55-65 per linear foot. Want glass panels? That’s $130-300 per foot. A typical 200 sq ft deck has 45-50 linear feet of railing, so this adds up fast.
Every pressure treated deck we install comes with our 2-year labor warranty, plus the Manufacturer Limited Warranty from MicroPro Sienna on the lumber itself. That’s real protection for your investment.
Pressure Treated vs. Composite – Which is Right for You?
We build both pressure treated and composite decks. Neither is “better” – it depends on what matters most to you.
Choose Pressure Treated If:
- Budget is your primary concern
- You like the look and feel of real wood
- You don’t mind spending a weekend every 2-3 years on maintenance
- You want to stain your deck a specific color (or change it later)
- You’re comfortable with a 15 year lifespan with proper care
Choose Composite If:
- You want zero maintenance (no staining, no sealing)
- You’re okay paying 2-3x more upfront for long-term savings
- You want a 25-50 year warranty on the decking material
- Splinters are a concern (kids, bare feet, pets)
Most Toronto homeowners we work with in neighborhoods like The Beaches, High Park, and Lawrence Park choose pressure treated when they want to maximize their outdoor living space within a budget. Composite makes sense when you’re building once and want to forget about maintenance forever.

Caring for Your Pressure Treated Deck in Toronto
Pressure treated decks do need some maintenance. Here’s what Toronto homeowners should know:
First Year
Let your new deck weather for a few weeks before staining. MicroPro Sienna lumber can usually be stained sooner than traditional pressure treated wood – often within 2-4 weeks once it’s dry to the touch. Test a small area with water. If it soaks in rather than beading up, the wood is ready for stain.
Ongoing Maintenance
- Sweep regularly to remove debris that traps moisture
- Clean annually with a deck cleaner and stiff brush (or pressure washer on low setting)
- Re-stain every 2-3 years to protect against UV damage and moisture
- Check for loose boards each spring and tighten as needed
- Clear snow carefully using a plastic shovel to avoid scratching
Protecting Cut Ends
When we cut pressure treated lumber during installation, we expose untreated wood inside. We always apply cut-end sealer (like Cut-N-Seal) to these exposed areas. This is actually required to maintain the MicroPro Sienna warranty. Some contractors skip this step – we don’t.

Frequently Asked Questions About Pressure Treated Decks
How Long Do Pressure Treated Decks Last in Toronto?
With proper maintenance, a quality pressure treated deck should last 10-15 years in Toronto’s climate. The lumber itself is warrantied against rot and decay. What typically fails first is the finish – that’s why re-staining every 2-3 years is so important. We’ve seen well-maintained pressure treated decks last 25+ years.
Is Pressure Treated Wood Safe for Kids and Pets?
Modern pressure treated wood like MicroPro Sienna uses micronized copper azole (MCA), which is much safer than older treatments like CCA (chromated copper arsenate) that was phased out in 2004. It’s certified UL GREENGUARD Gold for low VOCs and is approved for use in playground equipment. That said, wood splinters can develop over time, so keeping up with maintenance helps prevent this.
When is the Best Time to Build a Pressure Treated Deck in Toronto?
We build pressure treated decks from late March through November in most years. Spring and fall are actually ideal because the weather is mild and we’re slightly less busy than peak summer months. If you want your deck ready for summer entertaining, booking in early spring is smart.
Can I Build a Pressure Treated Deck in Winter?
Technically yes, but we don’t recommend it. Ground can be frozen, making post installation difficult. The wood is harder to work with in extreme cold. And you’ll be waiting until spring to stain anyway. If you contact us in winter, we can do a site visit and get you quoted so you’re ready to go when weather warms up.
What's the Difference Between Ground Contact and Above Ground Pressure Treated Lumber?
Ground contact lumber has more preservative treatment to handle direct soil contact. Above ground lumber is fine for deck boards and railings that stay dry. We always use the right grade for each application. You’ll see it marked on the end tag of each piece.
How Much Does a 12x16 Pressure Treated Deck Cost in Toronto?
A 12×16 deck (192 square feet) typically costs $7,000 – $12,000 installed with pressure treated MicroPro Sienna lumber and a small set of stairs. Price varies based on height, access, railing choices, and site conditions. We provide detailed quotes after a site visit.
Can You Remove My Old Deck Before Building a New One?
Absolutely. Deck demolition and disposal is something we do regularly. Depending on the size of your old deck, removal typically costs $500 – $2,500. We’ll include this in your quote if needed.
