Facebook Ads for Builders: Turning Scrollers into Extension Enquiries

Building work doesn't get bought on impulse. Someone thinking about an extension might spend months looking at photos, talking it over at home and asking neighbours who they used before anyone gets in touch. By the time they search "extension builders near me", they've often already got a shortlist in their head.

That's why Facebook and Instagram can work so well for builders. They let you get onto that shortlist early, while people are still dreaming about the project rather than comparing quotes.

Why Meta suits building work

Google is brilliant at catching people who already know what they want and are searching for it now. Meta works the other way round: it puts something in front of people who weren't looking for it yet. For a burst pipe that's useless. For a kitchen extension it's ideal, because:

• The work is visual. A good before-and-after does more selling than any amount of copy.
• The decision is slow. Ads can keep you in front of the same local homeowners over the weeks they spend mulling it over.
• The job is worth a lot. One signed extension can pay for months of advertising.

We go into when Meta beats Google more generally in do Facebook ads actually work for local businesses.

Use your own projects, not stock photos

The best-performing creative for builders is nearly always their own work. People can tell a stock photo from a real job, and real jobs build trust. Things that work well:

• Before-and-after photos of the same space, taken from the same angle.
• Short progress clips showing the build going up, filmed on a phone.
• Finished walkthroughs, ideally with the homeowner saying a few words.

Get into the habit of taking photos and a quick video on every job. It costs nothing at the time and it's the raw material for months of ads.

Let the algorithm find the audience

It's tempting to narrow the targeting right down to particular interests or ages. With Meta's current systems that usually backfires: the platform now does most of the targeting itself, based on who responds to your ads. Set a sensible area around the towns you cover, give it good creative and let it learn. We explain the changes behind this in Meta ads in 2026: what's changed.

Ask qualifying questions in the lead form

Meta's lead forms are quick for people to fill in, which is good for volume and bad for quality. You can fix much of that by adding a few questions you'd ask on the phone anyway:

• What kind of project is it?
• Roughly what budget do you have in mind?
• When are you hoping to start?
• What's your postcode?

You'll get fewer enquiries, but far more of them will be worth a site visit. Meta also offers a higher-intent form option that asks people to review their details before submitting, which helps filter out accidental taps.

Follow up fast

The quickest builder to respond often wins the visit. Someone who fills in a form on a Sunday evening and hears back on Monday morning is far warmer than someone who hears back on Thursday. Set up an instant automatic reply, then call or message personally as soon as you can.

Pair it with Google

Meta builds interest; Google catches the people who are ready now. Running a small Google Ads campaign for searches like "loft conversion [town]" or "extension builders [town]" alongside your Meta ads means you're there at both ends of the decision.

Judge it on signed jobs

Facebook leads usually cost less than Google leads, but fewer of them turn into work. That's not a failure, just a different kind of lead. Track enquiries through to site visits and signed jobs, and judge each platform on cost per booked job, not cost per enquiry. We explain why in why cheap leads are usually expensive.

Building projects take time to turn into contracts, so give any campaign at least three months before deciding whether it works.
