Is your contractor’s quote fair?
Sumwise reads your plans and tells you what the work should cost — an independent, itemized opinion of probable cost, priced to your region and delivered as a range with a confidence class. So you can sign, or push back, knowing where the number should land.
We’re an advisor, not a bidding tool. We give an opinion of probable cost at fair-market pricing — we never tell you what to bid or take a side in negotiations.

How it works
Upload your plans
Drop in the drawings or plan set as a PDF — a renovation quote's scope, a permit set, an architect's package.
We take it off, sheet by sheet
Sumwise measures the quantities from the drawings and prices them to your region using current cost data — not a rule of thumb.
You get an itemized opinion
A fair-market range with a stated confidence class, broken out by trade, with every line traceable back to the sheet it came from.
What makes a Sumwise estimate different
Itemized, never a black box
Every quantity cites the drawing it was measured from. You can see exactly what's included — and what isn't.
A range with a confidence class
We give an opinion of probable cost as a range with an AACE-style confidence class, never a single false-precision number.
Priced to where you build
Costs reflect your local market — Ontario first, more regions to follow. Location is built into every estimate.
Calibrated against reality
Built by a construction estimator and checked against real, published tender results — so the numbers stay honest.
Who it’s for
Homeowners & property owners
Planning a renovation, addition, or build? Check a contractor’s quote against an independent number before you sign — and budget with a range you can trust instead of a single figure.
Contractors & subtrades
Faster take-offs and a fair-market benchmark for your bids and budgets — itemized by trade, every quantity sheet-referenced, ready to price your way.
