Hidden cost

You’re overpaying up to 25% on construction materials

The same 2x4, the same drywall, the same shower: the price swings up to 25% from one store to the next. Without comparing them all, you go back to the store down the street and overpay on your project without knowing it.

Two Quebecers leveling the playing field for builders

Two friends from Quebec, same observation on every job site: blown-up material bills, prices that swing wildly store to store, and no simple tool to help people pay the fair price. Our mission: give the power back to the people who build.

Frequently asked questions about construction material prices

Do you have a mobile app?

No native app yet, but you can install Buildsavr on your phone in seconds. Open buildsavr.com in your browser, then tap "Add to Home Screen". The icon installs like a real app (it’s a Progressive Web App, or PWA) and opens full-screen, no App Store needed.

How do I compare construction material prices in Quebec?

With the Buildsavr app. You paste your materials list (text, photo, Excel, PDF or chat) and our AI compares prices across Quebec’s major hardware stores. In seconds, you get your cheapest buying plan, store by store, with the route and total savings.

Which hardware stores does Buildsavr compare?

RONA, Home Depot, Canac, Patrick Morin, BMR, Matério, Laferté, Gagnon, L’Entrepôt de la Réno and other Quebec banners. Coverage keeps growing as retailer partnerships come online.

Is the Buildsavr app free?

Yes. The free plan gives you 5 comparisons per month, no credit card. You only move to a paid plan if you want more comparisons or advanced features: photo, Excel and PDF import, retailer selection, contractor discounts applied and unlimited AI chat.

Can Buildsavr have my materials delivered to my job site?

Yes. On top of in-store pickup within your radius, you can choose delivery to your job site. We then compare the retailers that deliver to your address, anywhere in Quebec.

Where do the material prices come from?

Public weekly flyers from Quebec hardware stores, official retailer catalogs and publicly accessible sources, plus the retailers affiliated and partnered with us. Nothing unlawful.

How accurate are the compared material prices?

We compare the vast majority of popular construction and renovation products in Quebec, updated weekly. For items we don’t cover yet, we say so clearly rather than displaying an estimated price.

I’m a retailer or supplier: how can I receive qualified leads?

Buildsavr forwards partner retailers and suppliers qualified leads with the complete shopping list and confirmed purchase intent. Email partenaires@batirarabais.ca.
