Lead generation for windows and doors: +850 quote requests and a 1:10 return

The customer

3C Serramenti is a company specializing in the supply and installation of windows and doors for new homes and renovations, operating in multiple provinces. A solid brand with a strong local identity, it's also recognizable by its orange 3C logo , a distinctive element that has become a true symbol of recognition over time.

The point was not to improve the product, which was already competitive, but to make a qualitative leap in the way the company transformed interest into concrete requests for quotes .

The challenge

The initial problem was simple, but very widespread: there was no structured lead generation system .

Contacts arrived sporadically, without a clear logic, without tracking, and above all without any real quality control. This resulted in requests that were often generic, lacking in detail, and difficult to manage from a commercial perspective.

In the window and door industry, this is a critical point: every poorly qualified request means wasted time, poorly targeted quotes, and a real difficulty in converting marketing into revenue.

The goal was therefore not just to “generate more leads”, but to build a system capable of producing more informed requests for quotes that are closer to closing .

The approach

The work started from a precise logic: not to think about the channels, but about the customer's decision-making process .

Through the Connection Funnel, we've built a system that doesn't just capture interest, but progressively guides it toward a more structured request. In the window and door industry, the difference isn't made by the number of contacts, but by the level of clarity with which a person requests a quote.

The goal was therefore this: to transform a general audience into people who know what they want, already have an idea of the project and are ready to enter a concrete commercial phase.

The intervention

To achieve this result, we built a complete ecosystem, working in a coordinated manner on multiple elements.

The first step was to redesign the WordPress site , completely redesigned to increase conversions. This wasn't just a cosmetic update, but a structure designed to guide users, clarify the offering, and seamlessly lead them to requesting a quote.

We added an advanced tracking system with Google Tag Manager to this, which is essential for connecting each lead to its origin and clearly understanding what was working and what wasn't.

On the acquisition front, we've activated two main channels. On the one hand, Meta Ads campaigns with an internal module , useful for reducing friction in the initial phase and generating volume. On the other, Google Ads campaigns , designed to capture more informed demand, linked to specific searches for windows, doors, and quotes.

Once the contact was acquired, the work didn't stop. We implemented post-lead automations to support the user even after the request, increasing awareness and improving the quality of interactions with the sales team.

At the same time, a branding overhaul was also carried out. The logo restyling retained the iconic orange 3C element, but made it more contemporary and consistent with the new digital positioning.

A subtle but important task, because brand perception directly impacts the quality of the contact generated.

The results

Over the course of 2025, the system generated approximately 850 total leads , with a return of 1 in 10 compared to the total investment between management and advertising.

The leads generated aren't just generic inquiries, but contacts that arrive with a much higher level of detail: they indicate measurements, number of windows, desired features, and project context. In other words, they're not just "requesting information," they're already setting up a quote.

This has a direct impact on sales work. Conversations become faster, quotes are more focused, and the likelihood of getting the quote confirmed , which is the true final indicator of the project, increases.

Conclusion

The case of 3C Serramenti demonstrates a very simple thing: in the window and door sector, the winner is not the one who generates the most contacts, but the one who generates the best contacts .

When your website, campaigns, tracking, and brand work together, the result isn't just an increase in leads, but a change in the quality of demand. And when demand is more informed, the sales process also becomes more efficient.

This is where lead generation stops being marketing and starts becoming real growth.
