About Signmaster Plus

— Who We Are

A family-run GRP sign blank manufacturer,
making quality signs in Dorset for over 25 years.

Founded over 25 years ago in Dorchester, Dorset, our family-owned company has built a reputation for excellence in the GRP industry. What began as a small workshop with a clear commitment to craftsmanship and customer service has grown into a trusted local specialist delivering durable, precision-engineered GRP solutions across the region and beyond.

From the start, our approach has been simple: combine traditional workmanship with modern techniques and materials to produce products that perform and last. Over the decades we’ve refined processes, invested in staff training and equipment, and developed rigorous quality controls so every project, large or small, meets the exacting standards our customers expect. Our expertise covers design, fabrication, repairs and bespoke GRP installations for commercial, industrial and domestic clients.

As a small family business, relationships matter to us. We pride ourselves on clear communication, responsive service and taking personal responsibility for the work we deliver. Many of our customers return to us time and again because they know we stand behind our work and treat every job with care and integrity.

Rooted in Dorchester, we’re proud to support the local economy and contribute to projects across Dorset and the UK. Looking ahead, we remain committed to innovation and sustainability while keeping the same family values that have guided us since day one, quality workmanship, reliability and a genuine focus on customer satisfaction. If you’d like to discuss a project or learn more about our capabilities, we’re always happy to talk.

We pride ourselves on our personal and efficient service, alongside our unwavering attention to quality.

How We Make Our Signs

Every Signmaster Plus sign blank is hand moulded at our factory in Dorset using traditional hand layup methods — the same process we have used for over 25 years. This gives our signs exceptional structural integrity, a consistent surface finish, and the durability our customers rely on.

Our GRP fibreglass signs offer exceptional strength, weather resistance, and long-term reliability, making them ideal for pubs, shops, churches, commercial premises, and heritage applications. The surface is straightforward to apply vinyl and digital print to, and provides an outstanding blank canvas for traditional signwriters.
