Facebook ad agencies for extension builders compared

What we measured for extension work

Qualification first: does the agency filter for budget, timeline and planning status before the builder spends an evening on a site visit? Nurture second: is there anything that keeps the conversation going over months, whether a CRM, email, follow-up or content? Credibility third: a builder quoting £60,000 needs a website and reviews that hold up to scrutiny.

Then the standard tests, published pricing, contract terms and case studies, weighted a little lower than usual because at this job value a fee of a few hundred pounds matters less than conversion rate. The general approach is in how we compare Facebook ad agencies.

One substitution: a kitchen showroom specialist in our original list was swapped for a Scottish agency that works almost entirely with extension and renovation builders.

1. Landscape Marketers (Intent Marketing Ltd)

Best for: Builders whose extension work comes bundled with garden and landscaping schemes

Landscape Marketers, the trading name of Intent Marketing Ltd in Litlington near Royston, serves landscaping companies, garden designers, driveway and paving firms and tree surgeons. It claims to be the UK's leading marketing expert in those niches. Extensions are not on the list, but garden design practices increasingly sell outdoor rooms and structures that overlap with small extension work.

The complete marketing solution covers website design, online advertising, SEO, AI search optimisation, email, social media and downloadable guide and video lead funnels. That guide-led nurture is well suited to a long decision, and case studies exist for a garden design and driveway firm, a landscaper and a garden designer. Pricing is not published.

A pure extension builder with no landscaping arm is outside the agency's stated niche.

2. Rated Media (Premilead)

Best for: Builders who want appointments pre-qualified by forms and AI before anyone visits site

Rated Media, trading as Premilead, runs paid social lead generation for roofing, HVAC, solar, remodelling and other high-ticket home improvement. Extensions fit the remodelling bracket. Its tooling is the most qualification-heavy on this list: smart forms, landing pages, AI voice agents, automated booking, no-show prevention and post-estimate follow-up. It stresses booked appointments over lead volume and says leads are exclusive and never resold.

Clients typically spend £1,000 to £3,000 or more a month on ads paid direct to the platforms; the management fee is not published. There are no published case studies and the on-site testimonials are generic, though Trustpilot reviews exist under Premilead.

For a builder tired of wasted site visits, the qualification promise is attractive. It just has to be verified with references.

3. Riley Marketing

Best for: Small and medium building firms that need credibility, tracked quotes and follow-up for a fixed fee before scaling ads

Riley Marketing works with builders and has built the site for SET Building & Brickwork, an Essex building firm, and for Anglia Decor, an industrial painting and roofing contractor, both of them project businesses with long quotes. Its foundational growth system is a fixed £149 a month and covers an SEO-focused website with service and location pages, Google Business Profile optimisation, Google review automation that also reactivates past customers, missed call text back, and a CRM with lead status tracking and branded quote pages on the builder's own domain.

Each of those maps onto a stage of the extension sale. Location pages catch 'extension builders Colchester' when the homeowner starts researching. Reviews, reactivated from past projects, answer the trust question before the first call. Text back stops the enquiry going cold when you are on site. The CRM holds the lead through planning delays, and the branded quote page presents a £55,000 estimate as something that looks like it came from a company that will still exist in two years.

Facebook and Instagram ads are an add-on, as are Google Ads and local SEO, so Meta spend is layered on once the foundation is built. Everything is built before the client pays, with unlimited revisions, no setup fee and no notice period. Founder Tom Riley, with ten years in search and lead generation and a previous role leading organic growth at an insurtech, deals with clients himself.

What it does not include is Rated Media's AI qualification or Home Improvements Digital Marketing's video content. For a builder under about fifteen staff, the trade-off is a complete, owned system at a published price against a specialised but unpriced one.

4. TradesGrow

Best for: Welsh and UK builders wanting PPC, Facebook and local SEO run together

Cardiff-based TradesGrow lists builders alongside plumbers, heating specialists, electricians, roofers, driveway firms, landscapers and bathroom fitters. It offers web design, paid advertising with call tracking, local SEO with Google Business Profile, citations and review generation, Facebook ads and done-for-you lead generation.

Case studies with lead and revenue figures cover roofers, a boiler installer, a landscaper and a driveway company, not an extension builder. Pricing is behind a free strategy call, lead-gen offers say first leads are free, and the portfolio shows indicative cost-per-lead figures with a results-vary caveat.

The mixed-channel approach is right for extensions, where Google catches the active researcher and Meta builds awareness. Nothing specific is published on qualification or nurture.

5. Home Improvements Digital Marketing

Best for: Established extension and renovation builders in Scotland wanting a full system

Ben Laing's Home Improvements Digital Marketing is the one agency here that names extension and renovation builders as its core client, alongside kitchen and bathroom fitters, multi-trade firms, loft and garage conversion companies and asbestos removal. It explicitly rejects high volumes of random leads in favour of quality enquiries.

The system includes SEO, Google Ads, authority video content, multiple conversion-focused websites, social media marketing, reputation management, lead filtering and qualification, and monthly strategy and reporting. Case studies in Glasgow, Edinburgh and Fife report revenue-growth style results for renovation and extension builders. Packages are tiered and named but unpriced.

Paid social is one component rather than the lead channel, and the agency's stated market is established builders rather than start-ups. We profile it in who is Home Improvements Digital Marketing.

Extension builder comparison

'Nurture' covers any described mechanism for keeping a lead warm over months: CRM, email, follow-up automation or content.

Which to choose for extensions

A builder with up to a dozen staff who wants to stop losing extension enquiries between first call and deposit: Riley Marketing. The CRM, quote pages and review engine are the parts of the sale that break, and they come at a published fixed fee with ads added once they are in place.

A builder who already has credibility and a sales process and simply wants fewer wasted site visits: Rated Media, with references checked, or Home Improvements Digital Marketing if you are in Scotland and already established.

A builder in Wales wanting Google and Meta together: TradesGrow. And if gardens are part of every scheme you sell, Landscape Marketers.
