Website & Marketing Case Study: £100k Sales In Just 3 Months - For A Small, Family-Run Window & Door Company
by Will Williamson on 11-May-2026 10:00:01
This client is a family-run window and door installation company serving homeowners within a 20-mile radius. With 16 years in business and a strong local reputation, most of their work came from word-of-mouth referrals.
While referrals had sustained them for years, they were vulnerable. When recommendations slowed, so did enquiries. Their website was outdated, difficult to update, and generating only around 10 enquiries per month. They had no CRM system, no database, no email marketing, and limited visibility into what their advertising was actually producing.
Previous experiences with marketing providers had left them sceptical. Reporting was unclear, ROI was uncertain, and they felt pushed into services without transparency.
They wanted clarity, control, and measurable results, so they came to us because they to get everything in one place - SEO, Ads, website, tracking, with clear reporting.
Within weeks of their new website (which we built for them) they are seeing an immediate impact:
- 26+ leads generated through Google Ads
- 90% of enquiries classified as "high quality"
- Their surveyor’s diary filled consistently due to increased enquiry volume
- Website health score of 92%, placing it in the top 10% of websites
- £106,330 in confirmed business from website leads within 3 months of the website going live
Here's how we did it...
A Tailored Digital Marketing Programme
After conducting a competitor, keyword, and business analysis, we designed a tailored marketing programme that included:
- Marketing Strategy - We developed a plan to attract their ideal customers, including customer profiling and research into keywords and competitors to create a content and conversion strategy.
- Website Design - we created a custom design to modernise the look, feel and user experience of the site built on the HubSpot website platform.
- SEO (Search Engine Optimisation) - Ongoing SEO and AI Optimisation was also included to achieve high organic rankings on Google.
- PPC management - we set up and managed Google pay-per-click advertising for them.
- Lead Generation - We are applying several Conversion Rate Optimisation strategies to the website.
- HubSpot CRM - (Customer Relationship Management) - We introduced HubSpot as a way of tracking the source of all website enquiries, and have now trained the team on how to use it as a CRM system to manage their sales process, quotes and more.
- Access to JDR's Exclusive Video Training Hub - With training videos on sales, social media, video and much more.
The Results
Here are some of the key marketing achievements:
A Modern, HubSpot Website That Immediately Improved Performance
We rebuilt the website from scratch on HubSpot.
The new site:
- Achieved a 92% health score
- Is cloud-hosted and secure
- Integrates directly with their CRM
- Is fully owned and editable by the client
The feedback was immediate and overwhelmingly positive. The new site presents them as credible, established and professional, positioning them above many local competitors.

Enquiry volume increased almost immediately once the new site and tracking were in place.
Google Ads Delivered 26+ High-Quality Leads Within Weeks
This client had experienced disappointing results with Google Ads before, but we rebuilt their account strategically, giving them full ownership and tracking.
Within the first few weeks:
- 26+ leads generated
- High-intent phone enquiries
- 90% of leads classified as genuine
Every phone call is now tracked back to its source - so no more guessing, and no more confusion about which marketing channel generated which lead.

The client can now see exactly what is working.
SEO Progress Already Showing First Page Rankings
Despite the website being newly launched, early SEO progress is already visible.
One targeted phrase, “aftercare window”, is already ranking at position 10 on page one of Google, with multiple other keywords progressing upward.

This is the foundation for long-term, sustainable organic growth.
From Scepticism To Confidence
Before working with us, the client was cautious. Previous marketing experiences had left them uneasy and doubtful.
Now, they can clearly see that what we are doing is working.
Every enquiry is tracked. Every call is logged. Every campaign is visible in simple dashboards. No jargon, no smoke and mirrors.
They have moved from:
- Unclear ROI
- No CRM
- No lead follow-up process
- Limited visibility in Google
To:
- Clear reporting
- Structured lead management
- Multiple enquiry channels
- A scalable growth platform
In just 4 months, this family-run window and door installer has:
- Transformed their online presence
- Increased enquiry volume
- Improved lead quality
- Gained full clarity over marketing ROI
This has generated £106,330 in the first 3 months since the website went live.

Most importantly, they now have a structured, trackable system to support their goal of growing back to three fitting teams and beyond.
