About the author

Hi — I’m Azlan. I built this calculator because every deck quote my friends and family showed me started with the same line: “it’ll be somewhere between eight and twenty-five thousand.”That’s not a budget. That’s a shrug.

I’m based in Toronto and work on small software projects in construction, real estate, and consumer finance — spaces where the difference between a real number and a marketing number is the difference between making a good decision and a regret. After watching a few too many people sign deck contracts they didn’t understand, I built something for myself. Then I cleaned it up and put it online, because if it’s useful to me it’s probably useful to other people in the GTA looking at the same question.

Why I built this

Most online deck calculators are one of two things: a single dollars-per-square-foot multiplier that’s usually wrong by thousands of dollars, or a lead-generation funnel where the calculator is a bait-and-switch designed to land an under-priced quote and then upsell. Neither is what a homeowner actually needs.

What I wanted was something I’d have used myself before getting on the phone with a contractor: a real range, broken out by material, size, height, railing type, and the obvious finishes — built on numbers I’d be willing to defend if a builder pushed back on them. The goal is for you to read your contractor’s quote and understand which lines are normal, which are high, and which are worth questioning.

How the numbers are sourced

The pricing coefficients come from installed quotes I’ve seen on real GTA deck projects through 2024 and 2025, cross-checked against contractor pricing schedules where I could get them, and padded modestly to keep the high end realistic for 2026 conditions. They get reviewed before each major site update. Anywhere the model would require a number I couldn’t honestly defend — say, exact municipal permit fees that vary by lot — I leave it out and point you to the city’s building department instead.

The calculator always shows a range, never a single number. A quote that lands at the low end of the range usually has tradeoffs (fewer cuts, simpler footings, no lighting, basic railing). A quote at the high end usually has reasons (premium boards, tricky access, complex layout, integrated features). Both are legitimate. The middle is normal.

What I won’t do

• Track you across the web. Analytics on this site is cookieless and aggregated only. I don’t know who individual visitors are.
• Sell or auction contact details.If the lead form is on (it’s currently off while I rebuild that piece), it routes to a small set of GTA-based builders I’ve actually vetted — not a national lead network.
• Require contact information to use the calculator. The estimate is free, anonymous, and complete. You don’t owe me an email to see the breakdown.
• Publish AI-generated content as my own opinion. I use AI as a writing assistant, the same way most modern writers use a spellchecker, but every page on the site has been edited and fact-checked by a human (me) before it goes live. The pricing coefficients, the city-specific context, and the editorial framing are mine.

Where it’s going

The next phase is more depth on the city pages, a journal of practical long-form posts (composite vs cedar in southern Ontario winters, permit walkthroughs for each municipality, etc.), and a small developer API for anyone building tools on top of GTA construction pricing. The changelogtracks what’s shipped and the developer APIpage shows what’s available so far.
