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. builds the sales and marketing engine for established window and home improvement businesses. Every system we build, every campaign we run and every automation we configure is built specifically for this sector.
Our focus is the revenue-generating end of the pipeline — from first digital touch to confirmed appointment. Lead generation, pipeline conversion, follow-up discipline, content production and the AI systems that connect them. That's what we build. That's what we measure. That's where we produce results.
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× ROAS for ADS Windows, and 55% lead growth 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.
