A plain-English guide to running Facebook and Instagram ads for a building business. What leads cost, which projects pull, and how to handle the longer sales cycle.
Yes, but builders have to play a longer game than a plumber or electrician. Building work is a big, considered purchase. A homeowner doesn't see your ad on Monday and sign a contract on Friday. They see it, save it, show their partner, get plans drawn, sort finance, and book a builder months later. Facebook's job for a builder is to get you in front of those homeowners early, build trust with real project photos, and capture the enquiry so you're on the shortlist when they're ready. This guide walks through how to make that work, in plain English.
Quick note on wording. "Facebook ads", "Meta ads" and "Instagram ads" all run through the same platform, because Meta owns both Facebook and Instagram. For builders, Instagram pulls more weight than it does for most trades, because building is so visual. Great project photos can do real work in the Instagram feed, while Facebook captures the older homeowner planning a renovation. You're running across both and letting the system find the buyers.
Cost per lead depends on your city and your offer more than your trade. Across the NSW trade campaigns we run, cost per lead has landed roughly between $14 in regional areas and $44 in Sydney. Building leads often sit at the higher end, and that's completely fine, because one extension or renovation is worth tens of thousands of dollars. At $40 a lead, even if only one in ten enquiries becomes a job, that job dwarfs the entire ad spend.
The number that matters for a builder isn't cost per lead, it's cost per booked job against the value of that job. Budget around $300 to $600 a month in ad spend to start, plus a management fee for someone to set up and run the campaigns, and judge it over a few months. For the wider picture, see our guides on cost per lead for Sydney tradies and what Facebook ads cost for tradies.
Judge it on the pipeline, not the fortnight. A builder who switches ads off after two weeks because nothing's booked has misread the game. The enquiries you collect now are the jobs you sign in spring. Track leads and where they're up to, not just this week's bookings.
Both, doing different jobs.
Google Search catches people already looking. Someone searching "home extension builder near me" or "knockdown rebuild [suburb]" is high-intent and close to ready. A strong Google presence and Google Business Profile are hard to beat for those active searchers.
Facebook creates demand. It puts your finished projects in front of local homeowners who are dreaming about a renovation but haven't started ringing builders yet. Because building is such a long decision, Facebook's strength is getting you on the radar early and keeping you there while they plan.
Most builders do best with both: Google for the ready-to-go searchers, and Facebook ads filling the pipeline with planning-stage homeowners. We compare the two in Google Ads vs Facebook Ads.
Facebook works best for the visual, discretionary projects homeowners aspire to. The strongest performers for builders tend to be:
Commodity or urgent repair work leans more towards Google. Use Facebook to showcase your best completed projects to local homeowners in the planning phase.
From running trade campaigns, a few things separate the ads that pull from the ones that flop, and for builders the photos matter more than for any other trade:
Lead form ads are the best starting point, because they capture the enquiry while interest is high and remove the friction of a slow website. For builders there's a useful twist: a slightly longer lead form, with a question or two about the project type, budget range and timeframe, helps filter out tyre-kickers and gives you a real conversation starter. You'll get fewer leads, but better ones.
Traffic ads sending people to a gallery of your work can play a supporting role for awareness, especially with strong photos. But for capturing enquiries on a sensible budget, start with lead forms, and make sure you follow up fast and keep nurturing the leads who aren't ready yet.
Qualify, then nurture. A handful of well-qualified extension leads you follow up properly will out-earn a flood of cheap clicks every time. For builders, lead quality and follow-up beat lead volume.
Enquiries usually start in the first week or two, but booked jobs take longer because the building sales cycle is long. A homeowner might enquire in June and sign in September once their plans and finance are sorted. That's why builders should judge Facebook ads over three to six months, not a fortnight, and keep a simple system to follow up with leads who aren't ready yet. The pipeline you build now is the work you sign later.
Here's the short version for a builder thinking about Facebook ads:
Win one extension or renovation off a few months of leads and the ads have paid for themselves many times over.
