How much can you save on materials building your own house?

The spread on the same item between major banners runs about 10 to 25 percent in our Quebec observations. On a full material package that compounds: our co-founder took a $37,000 quote down to roughly $30,000 on an identical list, by pricing it across several suppliers instead of one.

Can you negotiate material prices at a hardware store?

On a single item at the till, no. On a house package quoted at the contractor desk, yes, and it is expected. Send the same itemized list to three or more suppliers, tell them you are comparing, and go back once with the best number.

Should I buy all my materials at the same store?

Almost never, if price is the goal. No banner is cheapest on everything, and the gaps move week to week. Buying everything in one place buys convenience, and on a full build that convenience is usually the most expensive line in the budget.

When should I buy materials to pay the least?

Buy in build order, when you need the phase, and let the flyer cycle work in your favour when the timing already lines up. Buying a season ahead to beat a price is a bet, and material stored badly loses more than the discount was worth.

How do I compare prices without calling every store?

Give your list to Buildsavr. It reads a typed list, a photo, an Excel file, a PDF or a chat, matches each line to the right product, and prices it across every retailer near you at once, then returns a store-by-store buying plan. It takes about 30 seconds, and the first comparison is free.

Does it work for a list of several hundred items?

Yes. A full house package is the case it was built for. The bigger the list, the more one-store buying costs you, and the less realistic it is to price it by hand.

How to save money building a house

By Simon Lafortune, Co-founder, Buildsavr · September 19, 2026

When people talk about saving money on a build, they usually mean doing more of the work themselves. That is real, but it is also the hardest, slowest lever you have, and it is capped by what you actually know how to do.

The other lever gets almost no attention and takes no skill at all: paying less for the exact same materials. Not cheaper materials. The same SKU, the same grade, the same brand, bought from whichever store happens to be cheapest on it that week.

A build is won on the material bill, not the labour

On a self-build, materials are usually the largest single line, and they are the line you have the most control over. Labour you either do or you pay for. Permits and services are fixed. Materials are a market, and markets have gaps.

Those gaps are bigger than people expect. Comparing the same items across the major banners in Quebec, we see swings of 10 to 25 percent on identical products, week to week, store to store. On a bathroom that is lunch money. On a house it is thousands of dollars, on materials you were buying anyway.

What $7,000 looks like in practice

Alexandre, who co-founded Buildsavr with me, priced a material package for his own build. The first quote came back at about $37,000. He took the same list to several suppliers, let them see each other, and ended up paying close to $30,000.

Nothing about the build changed. Same list, same grades, same quantities. The only thing that changed was who he bought each part of it from.

**That is the whole idea behind this company.** He did by hand, over days of phone calls, what no one with a day job has time to do. The product exists because that work should take thirty seconds.

Make suppliers compete for the whole package

A yard quoting a full house package behaves differently than a cashier ringing up eight studs. There is a real quote desk, real volume, and real room to move.

Send the same complete list to at least three suppliers. Same quantities, same specs, so the quotes are comparable.
Tell them plainly that you are getting other quotes. That is normal and expected on a package this size.
Ask for the quote itemized, not as one lump. A lump sum hides which lines are actually competitive.
Go back once with the best number. The second round is often where the real movement happens.
Ask what is included. Delivery, unloading and lead time are part of the price even when they are not on the invoice.

Compare before you drive, not after

The most expensive habit in a self-build is buying at whichever store you are already standing in. It feels efficient. It is the single reliable way to overpay.

Pricing online first costs nothing and takes minutes. The catch is that doing it properly means checking every item at every retailer, and nobody does that for a list of two hundred lines. That is precisely the part worth automating.

Play the flyer cycle, but check the regular price

Weekly flyers move real money on framing lumber, sheathing, insulation and drywall. Buying a phase the week its main material is on sale is free savings if the timing already lines up with your build.

**One caution.** A 25 percent discount off an inflated regular price is not a deal. Always check what the competitors charge for the same item at regular price before you treat a flyer as a win.

Where the savings actually hide, phase by phase

Not every phase has the same spread. These are the ones worth pricing carefully.

Framing package. The biggest dollar line and the most volatile. Price it as a package, not by the piece.
Sheathing and subfloor. Sold by the sheet, bought by the hundred, and priced very differently between banners.
Insulation. Bulky, promo driven, and frequently the widest percentage gap of any phase.
Drywall and compound. Heavy, cheap per unit, and delivery terms matter more than the sticker.
Fasteners and connectors. Small lines that add up fast, and the ones people never bother comparing.
Finishes. Doors, trim, paint and flooring, where brand pricing varies the most between stores.

The mistakes that cost the most

These are the ones we see over and over, and they are all avoidable.

Buying everything at one store for convenience. Convenient, and usually the most expensive possible outcome.
Buying the whole build up front. Material stored on site warps, walks, or gets rained on.
Comparing item by item instead of list by list. The savings live in the mix, not in any single line.
Ignoring delivery. Free delivery over a threshold can beat a lower unit price.
Forgetting waste factor, then making an emergency trip at full price for the last four sheets.

Do it in thirty seconds instead of three days

Buildsavr takes your list however you have it, typed out, a photo of a handwritten page, an Excel sheet, a PDF, or just by chatting with it, and prices every line across every retailer we cover at once.

What comes back is a buying plan: which store is cheapest for each item, your total, and what you save against buying everything in one place. You decide what is worth a second stop. The tool gives you the numbers instead of a guess.

It is live in Quebec today across Home Depot, Rona, Canac, BMR, Patrick Morin, Home Hardware and more. Everywhere else in Canada is a waitlist, and we open provinces in the order people ask for them.
