A deck built correctly becomes a permanent part of your home, one that holds its structure, retains its finish, and adds real value long after the build is done. That is the standard Allison Bros brings to every deck construction project in Ontario.
Deck Construction Services
Our Commitment to Provide Professional Deck Construction Services
Most homeowners searching for deck construction services want the same outcome, a structure that looks right, performs through Ontario’s seasons, and doesn’t demand constant upkeep once it’s built. That’s the standard Allison Bros has been delivering for over 20 years as a family-owned deck construction company.
Where other crews build to a template, we work differently. Every project starts with asking the right questions upfront, how the deck will function day to day, what conditions it needs to handle through the seasons, and what your budget realistically allows. Those answers shape a custom deck design that’s built around your property.
Whether you’re creating an entertaining area, a backyard retreat, or a structure that ties your outdoor space together, we build your deck around your life and to a standard that lasts.

FAQs
Frequently Asked Questions
What are the common deck building mistakes?
The most frequent ones we see are posts not set below the frost line, inadequate joist spacing, and skipped ledger flashing where the deck meets the house. Each one is preventable at the planning stage and expensive to fix after. Proper deck construction gets those decisions right before a single board goes down.
What is the average life of a deck?
A properly built deck using quality materials typically lasts 15 to 25 years – pressure-treated at the lower end, composite at the higher. Our deck construction service builds to the longer end of that range through correct material selection, proper framing, and protective finishes applied at the right stage.
Is it cheaper to repair or replace a deck?
Depends on what’s wrong. Surface wear is usually repairable. Structural problems – rotting posts, failing joists, compromised ledger connections – typically make replacement the smarter long-term decision. We start every assessment honestly so you know which one applies before anything gets quoted.
What not to do when building a deck?
Don’t set posts above grade, undersize the joists, skip ledger flashing, or seal unprepared wood. These are the shortcuts that turn a deck into a repair conversation within a few seasons. We’ve been delivering deck construction services in Oshawa, ON for over 20 years and our process is built around avoiding every one of them from the start.
What is the average cost to build a deck?
Costs vary by size, material, and complexity. A basic pressure-treated build typically starts around $15,000–$20,000. Cedar and composite options run higher depending on the scope. We provide clear, itemised quotes based on your specific property – no rough estimates that shift once the work begins.
