The marketing that books window jobs is narrower than most ad reps will tell you. For a replacement-window installer, four channels do almost all the work: a complete Google Business Profile, a handful of pages that catch people searching "window replacement [city]" and "cost to replace windows," paid search or Local Services Ads, and reviews collected after every install. A full-home window job runs $8,000 to $20,000, so one booked estimate usually covers a month of spend — which changes the math on every channel below.
We build and run the website, lead capture, and SEO engine for home-service companies — and we run our own HVAC and cleaning companies on the same stack — so this is the order we'd actually spend a window installer's first dollars in, not a list padded to sound thorough.
The single biggest lever and it costs nothing. Window buyers compare three installers; the one with 80 reviews and real install photos wins the visit. Pick the right primary category, post before/after photos from real jobs, and ask for a review after every install. Most installers leave this half-built.
Replacing windows is researched for weeks. Pages on cost by window count, vinyl vs. fiberglass vs. wood, energy-rebate eligibility, and "[city] window replacement" each catch a buyer mid-decision. They compound — a page written once keeps booking estimates for years, unlike an ad that stops when the budget does.
Local Services Ads put you at the very top with a "Google Guaranteed" badge and charge per lead, not per click — a strong fit for a high-ticket job. Search ads work too, but only if conversions are tracked so the algorithm optimizes toward booked estimates instead of clicks. Turn these on after the profile and call handling are solid.
A finished install is its own billboard. Door hangers on the surrounding ten houses, a yard sign during the job, and a referral ask convert cheaply because neighbors see the work daily. It won't scale alone, but the cost per booked estimate is hard to beat.
A booked estimate is not a sale. Work the funnel backward before you set a budget:
We turn down work that won't pay off. Hold off if:
If you're a one-crew installer in a small market, a strong profile and steady reviews may be all you need — and that's free. We'd rather tell you that than sell you ads you don't need yet.

Start with a complete Google Business Profile and steady reviews, add a few cost and city pages, then layer Local Services Ads or search ads on top. Follow up around finished jobs with door hangers. That order spends the least to book the first estimate.
Roughly 5 to 10 percent of revenue, often $1,000 to $5,000 a month for a small installer. Because a job is worth thousands in margin, a single booking usually covers the whole spend — so judge it on cost per booked estimate, not per click.
They benefit from them more than most trades because the intent is high and the ticket is large. But ads only pay when calls get answered and estimates get scheduled, and when conversions are tracked. Build that foundation, then turn ads on.
