Got referred to these guys by a friend and I’m glad I went with them. I expected it to be more expensive, but the price was fair for the quality. Materials look great and the install is nice and clean. Also appreciated that they cleaned up everything after , not everyone does that. Overall, great experience.
I’m really happy with my new deck! The team did a fantastic job. They listened to what I wanted, and it turned out just as I imagined. Great work!
The XP Decking company was really easy to work with. They kept me updated, finished on schedule, and the deck is solid and looks great. I’m so pleased.
Pressure-treated decking is one of the most reliable, cost-effective choices for Ontario homeowners looking for strength, value, and all-season performance. Reasons pressure-treated decks are an excellent choice include:
Ontario’s weather can be tough on outdoor wood. We use ACQ-treated lumber that’s rated for ground contact and built to handle heavy snow, wet springs, and summer heat.
The wood we use is pressure-treated with preservatives that help prevent rot, decay and insect damage, three of the most common reasons decks fail early.
Once the boards have dried out, they’re ready for stain or paint. It’s a great way to customize the look and add extra protection against the elements.
Pressure-treated decking is more affordable than cedar or composite deck. It’s a smart choice if you want something strong and good-looking without overspending.
This lumber is structural as well as visual. It’s load-bearing, and we use it for deck frames, joists and beams so your deck stays solid and safe for years.
We custom build every deck using pressure-treated lumber rated for ground or above-ground contact, delivering strength, safety, and style in any layout. Our popular deck style includes:
For flat backyards, ground-level decks in .40 ACQ-rated pressure-treated wood are stable and the lowest-cost option. We install with proper drainage, joist spacing, and moisture barriers to avoid sagging or rot. Others skip these details, and we don't.
Our multi-tier designs use engineered pressure-treated posts and framing to handle elevation changes, slopes and landscape features. Every level is secured with stainless steel fasteners and joined with clean transitions, so the steps stay firm and quiet.
We build pool decks with ground-contact rated PT lumber that resists chlorine, humidity, and UV. Slip-resistant finishes and gap spacing improve drainage and safety. While others cut corners, we build for long-term function and code compliance.
For homes with rear walkouts, we frame landings with double beam support and install custom staircases with reinforced stringers. Our decks handle Ontario freeze-thaw cycles better, thanks to proper footing depth and correctly installed flashing.
Second-storey decks need real strength. We use pressure-treated structural posts, lag-bolted ledger boards and braced beams to handle load and wind, and we build to the Ontario Building Code so the deck stays level and rigid.
Whether you need a deck attached to your home’s frame or a freestanding floating deck, we build both with joist hangers, rim boards and ACQ-rated framing anchors. Some installers skip permits; we obtain them, have the work inspected, and build to last.
We custom build every deck using pressure-treated lumber rated for ground or above-ground contact, delivering strength, safety, and style in any layout. Our popular deck style includes:

| Cost | ★ Affordable | Moderate | Expensive |
| Maintenance | Moderate | Moderate | Low |
| Resistance | High | Moderate | Very High |
| Lifespan (avg.) | 15–20 years | 20 years | 25–30 years |

Contact UsA pressure-treated deck can last 15–20 years or more, but like anything outdoors, it needs some basic care to stay safe and looking good. Here’s how we recommend keeping yours in top shape:
After installation, your deck needs time to dry out, because new pressure-treated lumber has a high moisture content. Wait at least 30 to 60 days before applying stain or paint, and longer in shady or damp areas.
Use a high-quality, semi-transparent stain that’s designed for pressure-treated wood. This helps protect against UV damage, moisture, and surface cracking.
Sweep off leaves and debris regularly, and give the deck a deeper clean each spring with a deck cleaner or mild soap and water. Use a pressure washer only with care, because it can damage the wood fibres.
Once a year, check fasteners, deck railings, and stairs. Tighten any loose screws and replace corroded hardware to keep the structure solid and safe.
Make sure the space under your deck isn’t blocked. Good airflow lets moisture escape and keeps the wood from staying damp, which is key to preventing rot.
Stick with breathable outdoor rugs. Rubber-backed mats or anything that holds water can create mould spots or lead to wood damage over time.
We inspect soil grade, drainage, and layout, then measure and flag everything. Our pros discuss railings, stairs, framing specs, and local bylaw needs.
You’ll receive a detailed quote with a 3D layout, lumber specifications, and railing and stain options, along with clear pricing and practical advice.

Pressure-treated wood can shrink, warp, or crack if not handled properly during installation. It also requires drying time before staining. That’s why it’s important to work with pros who understand how to prep and install it right.
A basic 10x10 pressure-treated deck in York Region usually costs between $2,500 to $4,000, depending on framing, ground prep, railings, and other custom features.
Yes, it’s a smart choice for durability and value. It’s resistant to rot, decay, and insects, making it ideal for outdoor use in Ontario’s climate, especially if you're building on a budget.
Never burn pressure-treated wood, because it releases toxic chemicals. Also avoid using it for countertops, garden beds or anything in direct contact with food unless it is rated for that use.
With regular care like sealing and staining, a pressure-treated deck can easily last 15 to 20 years or more in Ontario conditions.
Wait about 30 to 60 days after installation. The wood needs to dry out before it can hold stain properly. We can test moisture levels for you before sealing.
Modern pressure-treated wood is considered safe for residential use. It’s treated without arsenic and is commonly used in homes, decks, and outdoor living spaces across Ontario.
