Most builders, and tradespeople more broadly, end up running Facebook ads for the same reason: the phone's gone quiet, referrals have slowed for a few weeks, and it's the fastest thing to switch on. An ad can be live within the hour, targeted down to the suburbs you actually want to work in.
That speed is real. So is what shows up a few months in, once the cost per enquiry has crept up and half the leads turn out to be homeowners who were only ever after a quote to compare. Here's what Facebook ads actually cost Australian builders right now, what they're genuinely good at, and where they fall short.
How much do Facebook ads cost in Australia?
Costs vary by suburb, season and how competitive your trade is locally, but the direction of travel is consistent: up. Facebook ad costs in Australia have risen roughly 30 to 40% since 2023.
As a rough 2026 budgeting guide: expect somewhere between $0.75 and $5.30 per click depending on targeting and creative, with the national average sitting around $1.47 per click. Cost per lead is harder to pin down for building specifically, since most published Australian benchmarks group by broad category rather than by trade. That same 2026 benchmarking splits cost per lead by category: $40 to $80 for home services, $80 to $150 for real estate and other considered, higher-value purchases. A building or renovation enquiry sits closer to the second group, so budget toward that end rather than the cheaper one. December is also reliably the priciest month to advertise, since every trade and retailer is bidding for the same audience at once.
What Facebook ads do well for builders
- It shows finished work, not a pitch. Facebook is built for photo and video, so a completed extension, a before-and-after renovation, or a walkthrough of a build in progress carries more weight than a written quote.
- Targeting is precise and local. You can set a radius around your service area down to the suburb, so spend doesn't leak into postcodes you'd never take a job in.
- You control the switch. Launch, pause, adjust the budget or swap the creative the same day, without waiting on an agency or a directory listing to refresh.
- Retargeting keeps you in front of warm traffic. Someone who watched 15 seconds of a renovation video or visited your website can be shown a follow-up ad, rather than competing cold for their attention again.
- The lead is yours alone. Unlike shared lead marketplaces, an enquiry from your own Facebook ad doesn't go to three other builders at the same time.
Where Facebook ads fall short for builders
- Costs keep climbing. See the pricing breakdown above; the trend is up year on year, and it's not slowing down.
- It's an interruption, not a search. Someone scrolling Facebook wasn't looking for a builder when your ad appeared. Someone typing "extension builder [suburb]" into Google was. That gap in intent is a big part of why Facebook enquiries tend to convert to booked jobs at a lower rate than enquiries from active searchers.
- Performance moves without warning. Tracking changes, algorithm updates and rising competition in the auction can all shift your cost per lead month to month, with no action needed on your part to cause it.
- It needs ongoing attention. Creative goes stale within weeks, not months. Running Facebook ads properly means testing new video and images on a rolling basis, which is either your time or an agency fee on top of the media spend.
- Nothing compounds. Stop the budget and the enquiries stop the same day. Unlike a review base, a referral network or an organic search ranking, a Facebook ads pipeline doesn't keep working while you're not paying for it.
Are Facebook ads worth it for a building business?
Facebook ads are a genuinely good way to show off finished work and stay visible in your local area, particularly stacked with retargeting once someone's already looked at your page. They're a weaker choice as your only source of leads, because you're paying rising prices to interrupt people who weren't looking for a builder yet, and every enquiry still needs to be requalified before you know if it's worth quoting.
The builders who do best treat Facebook ads as one channel within broader marketing for builders, not the whole pipeline. What's worth stacking alongside it is a way to reach homeowners who are already committed, before they've started comparing quotes at all.
Buildscout works earlier in that timeline. It flags homeowners the moment they lodge a development application, when the project is real but the shortlist of builders hasn't been drawn up yet. See how Buildscout works for SME builders or book a demo to see it against your own area.
