Who We Help

Built for windows & doors installers who can close, but can't get enough booked in.

You're good at converting in the home. The bottleneck was never closing. It's a consistent flow of qualified homeowner appointments into the diary.

You're a proven closer

You convert roughly 1 in 3 surveys. You don't need to close better. You need more qualified appointments to close.

You live feast or famine

Booked solid one month, staring at a cliff the next. A quiet week now is a cashflow hole at install time in two months.

You've been burned by "leads"

Renters, tyre-kickers, £200-repair enquiries and form-fills that never answer the phone. We book appointments, not leads.

You want to own your region

One installer per area. Every pound you invest compounds for you and locks your local competitors out.

Featured Case Study

How Greencastle generated £82,477 from £3,651 in ad spend.

Their previous agency was charging over £125 per lead. We brought it down and changed the kind of lead entirely.

In a single month we generated £82,477 in sales from just £3,651 in ad spend, a 22.6× return. The difference wasn't more leads. It was qualified homeowners, booked into the calendar, ready to buy.

"We genuinely didn't expect results this fast. The AI bot handles everything. It books appointments with homeowners who are genuinely interested. They show up pre-qualified, already know our pricing, and are ready to book a survey."

The Offer

We only get paid when you do.

No retainer, ever. A one-time setup, then commission only on the sales we generate, and not a penny until the cash is in your account. One installer per region. Built to generate around £250,000 of new work over six months, with roughly 30+ installs booked straight into your diary.

Based on our flagship client's blended results. Not a guarantee. Results vary by market, ad budget and your close rate.

Regional Availability

One windows & doors installer per region.

To protect your results, we never run campaigns for two competing installers in the same area. Once your region is taken, it's closed, and your local rivals are locked out.

FAQ

Questions windows & doors installers ask us.

Most agencies sell you raw leads, form-fills you have to chase, half of them tyre-kickers. We don't. We book pre-qualified homeowner appointments straight into your calendar: homeowner confirmed, in your area, with a real timeline. You spend your time quoting, not chasing.

There's no monthly retainer, ever. We're paid on performance: a one-time setup, then commission only on the sales we generate, and not a penny until the cash is in your account. We carry the cost of building and running everything up front. We'll walk you through the exact numbers for your area on the call, with no pressure.

You do, paid directly to Meta and Google, never through us. That keeps everything transparent: you see exactly what's spent and what it returns. Our fee is separate, and performance-based.

We're typically live within four weeks. We build the system, shoot your video ads, get your approval, then launch. The first booked appointments usually land within 48 hours of going live.

No. One windows & doors installer per region. Once your area is taken, we lock your local competitors out, and it's the fairest way to protect your results, which is why some regions are already closed.

Show up to the appointments and close them like you already do. We handle the ads, the creative, the AI qualification and the booking. You're freed up to do the part you're best at.

Then we've spent our own time and money for nothing, because we don't get paid until you do. There's no retainer feeding us a fee while your diary stays empty. We're on a one-time setup plus commission on the sales we generate, payable only once you've collected the cash. That's exactly why we set our forecasts conservatively. Hitting them is the only way we earn anything.
