Professional sign maker in Portsmouth

Over the last 50 years we have built up an enviable reputation in Portsmouth as the city’s one-stop sign maker solution. From shop fronts and billboards, to van signage and wall mountings, we can make any kind of sign that you might require for your business. As the foremost sign company in the area, we pride ourselves on the personal and professional service we provide. We will work alongside you from day one, assisting you through the initial design stage with our years of experience, and then transforming that vision into a solid range of signs that will draw the attention of your clients. As firm believers in the value of branding and platform-building, we make every effort to make your signs accentuate the values and image of your business.


Here's just a sample of the services we provide as Portsmouth’s top sign company.

Shop fascias

A well designed and produced fascia is perhaps the most essential investment any enterprise can make for the growth of their business. Not only do they signpost customers to your establishment, they act as a 24-hour advertisement when people walk by. A striking design is vital to attract the attention of potential clients, and it helps to establish you brand in the local market and beyond.

Vinyl signs

With your main shop fascia out of the way, you need to consider other signs both inside and outside the property. As vinyl sign makers, we use the finest materials specially chosen to be lightweight, durable, and scratch-resistant, for both indoor and outdoor use.

Point of sale displays

Once your customers are in your store, further signage is useful to direct them towards your special offers, and other items of interest. With a fast and effective digital printing service on site, we can produce attractive point of sale signs very quickly, as and when you need them. Our sign maker experience means that, even here, clarity and quality is assured.


Whether it’s for a convention or a private function, quality printed banners naturally draw the eye in their direction. With the equipment at our disposal as Portsmouth’s premier sign company, we can produce banners up to 30 metres in width.

Window signage

Attractive window signage, be it text, graphics, or a combination of the two, can really draw attention to the goods you have on display. Whether you’re furthering your brand with the store’s name and logo, or highlighting a seasonal sale, we can produce attractive window decals for you, and apply them to guarantee a smooth finish.

Van signage

As the area’s top sign company, we know that if there is one thing guaranteed to boost awareness of a company’s brand, it is clear and beautifully applied vehicle livery. Using your corporate colours as a base, and building on it with eye-catching text and graphics, we can create effective mobile marketing for your business.

Estate and commercial agents

We offer a unique sign maker service to estate and commercial agents in the area. As well as helping with your design, if needed, we will produce robust and hard-wearing signs for each of the properties in your portfolio, creating a uniform look that enhances your brand, and we will even install them at the properties for you.

We have been designing and producing the highest quality signage to our clients in Portsmouth and the surrounding areas for over 50 years, and have built a reputation for our professional service, and exceptional products.
