The rollout

Which province opens next? You decide.

We open provinces in the order people ask for them. Every province is at zero today: the first signups set the order.

Add your province

You sell materials

Put your prices in front of the contractors and homeowners who are shopping. You choose the audience.

No subscription, no commission.

You bid on projects

Verify your rep’s price in 30 seconds and claw back 5 to 10% on your materials. Every dollar counts toward your margin.

Carpentry, decks, sheds, fencing, drywall.

You’re renovating your place

One reno, one budget. We compare 800 stores and build your lowest buying plan. Save thousands of dollars.

I’m renovating

Kitchen, bathroom, basement, roofing.

You’re building your home

From foundation to finish. Hundreds of items, all at the best price, store by store. Keep control of the budget.

I’m self-building

Framing, insulation, doors and windows, finish.

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.
