A homeowner replacing windows is doing arithmetic. How many, which rooms, all at once or the back of the house first. Here is what a window lead costs on Facebook, why that count question changes what your ad should say, and how the first cold snap of fall moves your numbers.
Windows get put off for years and then get urgent in about a week. The draft that was annoying in October is intolerable by December. The window painted shut since the last owner is the reason nobody opens that room. The panes fog and quietly stop being windows. None of it is new. What changes is the weather.
Then comes the part that makes windows hard to advertise. A homeowner does not buy a window, they buy however many the house has, and the number in their head is almost never the number on the quote. An ad aimed at the whole house loses people at the arithmetic. An ad aimed at the one window that bothers them most gets the call, and the full count comes up on the estimate where you are there to explain it.
Timing is the other lever and it is predictable. The first cold snap of fall is the week homeowners feel the glass and then open the heating bill, and most window contractors have nothing running. Being in the feed through that stretch is worth more than spreading the same budget evenly across the year.
The honest answer is a measured number, not a range somebody guessed. Across every ad and every season for three years, Facebook and Instagram produced 237 landing-page leads at $112.17 each on $26,584 of managed spend, on a window replacement account. Those leads are for whole-home window replacement jobs that run $8,000 to $15,000, and that pairing is the whole point: a lead at $112 for a job at $12k is about one percent of the job. A single strong campaign on the same account can come in well under that three-year average, which is what the case study below shows.
Three things move the number for your account. Your market and the month you launch, since window replacement searches peak in July and August and every company bids hardest then. Your creative and offer, the biggest lever, because footage of a real fogged-pane install beats a stock photo with "free estimates" under it. And your targeting, where a tighter radius of older, owner-occupied homes costs a little more per lead and produces appointments worth driving to. A window replacement client reports booking 45% of the leads we generate; in a different period the same client reported 50 to 60%. At the 45% booking rate the client reports, that's $249.27 per booked estimate.
The full breakdown, with a budget table you can run your own numbers through and the minimum spend before the number means anything, is on what Facebook ads cost for a window company.
Not a case study we made up. Real ads, real spend, real leads.
We ran a window replacement campaign for Elevate BLD, a window contractor serving the Greater Sacramento area with 100+ five-star reviews, a direct dealer relationship with Anlin Windows, and a 24-hour quote turnaround. The creative was simple and honest: video ads built around the everyday pains of old windows (drafts, fogged glass, rising energy bills) paired with an offer built to stand out in their market.
Across roughly two months of ads we spent about $4,211 and brought in 54 window leads at an average of about $78 each, with the best-performing ad landing leads around $63. For a full-home window job that closes in the five figures, that's the kind of lead cost that pays for itself many times over.

"Our home feels brighter, quieter, and more energy efficient. Couldn't be happier. Highly recommend!"
"The windows look great and work perfectly. We're really happy with the results and would definitely recommend them!"
Early on, the fastest way to get a window campaign working was a straight discount. And it worked. But discounts have a shelf life. Once one contractor in a market runs a price cut, everyone copies it within a few months.
Suddenly every ad in the feed looks the same, the discount stops standing out, and all it does is train homeowners to shop for the lowest price. That's a race to the bottom, and it's a bad place for a contractor who does quality work to be.
So we changed our approach. Instead of racing competitors to the bottom on price, we build each window client a custom offer designed around what makes their business different, not a discount anyone can copy.
We won't spell out the exact offers here, because the whole point is that they're built to stand apart from whatever your competitors are running. But the idea is simple: give homeowners a reason to choose you that has nothing to do with being the cheapest. You get the same lead volume, better-quality homeowners, and an offer your competition can't just screenshot and steal.
Window replacement has a rhythm, and most contractors either ignore it or let it run their business for them. Demand climbs in spring and stays strong through summer, when the weather is good and homeowners are thinking about comfort and curb appeal. That's when the phone rings on its own, and it's also when every competitor is bidding hardest, so lead costs creep up.
The mistake we see contractors make is going quiet in the slow months and then scrambling to turn ads back on when they're already busy. That's backwards. The smartest play is to keep a presence year round and lean into the seasons deliberately.
The first cold snap of fall is a window most window contractors underuse. When homeowners feel the draft coming through the glass and watch their heating bill jump, they suddenly have a reason to act now, and a well-timed campaign speaks directly to that.
In the off-season, ads are cheaper and competition thins out. That's the time to fill your winter and early-spring schedule at a lower cost per lead, so you're booked solid before the busy season even starts.
Windows also pair naturally with other exterior upgrades, so a homeowner shopping for siding is often a homeowner who needs windows too. We build campaigns that flex with the calendar instead of fighting it, so your slow months get quieter for the right reason: because you're already full.
If you've bought leads from Angi, HomeAdvisor, or a similar service, you already know the problem. The lead you just paid for was sold to three or four other window contractors at the same time. You're not calling a homeowner who chose you. You're racing to be the first of five to call a stranger who filled out a form to compare prices.
That's the core difference. Lead-selling apps sell shared leads. Your own Meta campaign generates exclusive leads that belong only to you. The homeowner saw your ad, your work, your offer, and reached out to you specifically. You're not the cheapest of four or five quotes, you're the company they already trust.
The math matters too. A shared lead might look cheaper up front, but when you factor in how many you have to buy to win one job (because you're splitting every lead with competitors), the real cost per signed contract is usually higher. With your own campaign, every lead is yours, your close rate goes up, and you're building your brand in the market instead of renting someone else's.
There's a place for both, especially early on. But if you want predictable, exclusive leads that don't have your competitors' phone numbers attached to them, your own Meta ads win almost every time.
