The sales and marketing engine
for established window businesses.
We exist because serious window businesses deserve a growth partner who understands their world — not one that adapts a generic agency model and hopes it fits.
A boutique specialist team
focused on revenue.
Window Growth Co. didn't start with a grand plan. At the end of COVID, I lost my job. The first business that took a chance on working with me was a window company. We got serious results, quickly — and six years on, they're still a client.
That longevity taught me something more valuable than any campaign metric: when you stay close to one sector, everyone wins. The lessons learned with one client make the next one sharper. The patterns become clear. The system gets better. And the clients benefit from six years of accumulated knowledge that a generalist agency simply can't offer.
So I made a deliberate choice to go narrow rather than broad. Not because I have a lifelong passion for windows — but because I understood that depth beats breadth when it comes to building something that actually works.
Window Growth Co. now exists to do one thing: build the growth infrastructure that established window businesses are missing. Not leads. Not ads. The whole system — from how you generate enquiries digitally to how fast you quote, how consistently you follow up, and how clearly you can see what's working.
Six years in one sector. A Chartered Marketer. And a first client who's still here.
That's not luck. That's what a system does.
The team behind the system.
Window Growth Co. is a specialist team of practitioners — every discipline focused exclusively on the window and home improvement sector.
Marketing & Sales Strategists
The strategists who design your lead generation campaigns, set performance benchmarks against real window industry data, and ensure every pound of marketing spend is tracked to jobs won.
Software Developers
The engineers who build the custom applications, automation logic and technical integrations that make the whole revenue engine work as a single unit.
Automation & AI Specialists
The team who build and maintain the automated follow-up sequences, AI response bots and nurture workflows. Trained on your products, your language and your customer journey.
Designers & Content Producers
The creatives who build the content production engine — turning every completed installation into reviews, case studies, before-and-afters and social content, distributed automatically.
Computer Scientists & Data Analysts
The analysts who build the reporting systems and interpret what the data is telling you. They translate lead volume, conversion rates and revenue figures into decisions.
How we operate.
Selective by design
We work with a small number of businesses at any one time. Every client gets direct access to the specialists doing the work, not account managers reading from reports.
Sales and marketing machine
Our focus is the revenue-generating end of the pipeline. We don't manage operations, installation scheduling or post-appointment processes. We make the phone ring and the diary fill.
Data before instinct
Every decision is benchmarked against real window industry data. We report on cost-per-lead, cost-per-appointment and cost-per-job. If it doesn't show up in your pipeline, it doesn't count.
Results we stand behind
Verified outcomes: 7,080% ROAS for Roofriendly, 50%+ more appointments booked outside business hours for ADS Windows, and 15% Sales Growth Year 1 for Strata. These are the outcomes we measure against.
Area exclusivity
One window business per region. Your investment builds your advantage — not your competitor's. We commit to this before we take your money.
Growth requires change
More marketing spend without a functioning sales system makes the problem worse. We help you build the solution. We're a growth partner, not a campaign manager.
"We do not scale chaos.
We only scale systems."
This isn't a tagline. It's the filter we apply to every business we work with. If you're running a serious window business and want a partner who understands what that means — let's talk.
