Hardwearing and durable GRP (Glass Reinforced Polyester) or fiberglass garage doors are renowned for their stability, strength and resilience. They are lightweight and durable enough to withstand rust, splitting or rot and can endure harsh weather conditions, as well as minor bumps and knocks without compromising the security or appearance of your garage door. They’re perfect for recreating stunning designs that are typically made from wood but are more affordable and without any of the maintenance concerns.

Design Choices for GRP Doors

While you may want a simpler garage door design, there are ways to customise your door to create a more bespoke look. In addition to the mechanism of the door, such as automating your door for added convenience and speed, you can also choose a door with windows that let in plenty of light to your garage and are aesthetically pleasing for added kerb appeal.

There are plenty of colours to choose from too, to suit your personal taste or to match the style of your property. You may also want to upgrade the locking system on your door for higher security or replace your timber sub-frame with a steel version for added durability and strength.

CDC Kingston Double Doors

Naturally impact-resistant – GRP can withstand knocks and dents with ease, so it’s not going to be damaged easily. GRP is incredibly stable and has been tested thoroughly, so it’s ideal for providing durability and maintaining its aesthetic appeal for years to come.

Resistant to shrinking and warping – Unlike wooden doors, which can be prone to warping or shrinking if they’re not properly maintained, GRP is low maintenance and won’t change size or shape when exposed to the elements.

Attractive appearance – GRP doors come in a range of styles to suit your property, from high gloss finishes to wood replica doors that mimic the look of woodgrain, to gel-coat layers which create a moulded design.

Environmentally friendly – Since GRP is made from gentle compounds that are largely naturally occurring, and is also often made from grinding and re-using fillers with no long-term negative effects to the planet, GRP can be seen as an environmentally kinder material.

Greater security – GRP offers an excellent strength to weight ratio, meaning it provides fantastic levels of security for your garage and home.

Fiberglass Garage Doors

GRP, or fiberglass, garage doors are the perfect lightweight, maintenance-free material for the construction of high quality, long lasting garage doors. They come in a variety of styles including up and over garage doors, roller garage doors, sectional garage doors and automated garage doors. Once you’ve chosen your colour and finish, they need no staining or protective finishes to preserve their stability and appearance.

Up and over garage doors are a safe and reliable solution and represent excellent value for money. They’re an extremely popular choice for homes everywhere. Our GRP up and over garage doors are available as ribbed and panelled designs, either as canopy or retractable doors. They look great in a choice of colours and long-lasting finishes that suit both modern and traditional properties.

Sectional garage doors are made up of separate sections rather than a single panel, so they open with virtually no loss of driveway space and with full opening drive-through width, perfect for wider vehicles. Sectional fibreglass garage doors offer excellent single skin or double skin thermal insulation, and rubber weather seals on all sides. Available in high gloss or fine wood effect finishes.

Roller garage doors have a space saving design that is perfect for short driveways and easy access. Open, the rolled-up door stores safely in its own compartment at the inside top of the garage. Closed, the absence of visible locks and handles offers unrivalled security. Our GRP doors are fully powder coated in a variety of finishes, and can easily be automated for complete peace of mind.

Automated garage doors offer the best in user convenience and enhanced home security, with a remote-controlled system that helps you future proof your home. We can install a brand new electric GRP garage door or retrofit automation to your existing door, ensuring many years of fuss-free, low-maintenance operation.


  • What are GRP garage doors made from?

    GRP, or Glass Reinforced Polyester, is a versatile composite laminate that’s made from polyester resins which are reinforced with glass fibres to create a remarkably strong material. GRP can replicate the textures of other natural materials, such as wood, using moulds to create an effective replica that boasts the aesthetics of the material with the strength and durability of GRP.

  • Can GRP garage doors be repaired?

    Yes, one of the major advantages of choosing a GRP garage door is how easily they can be repaired if they become damaged. A scratch, dent or small hole in your garage door can almost always be repaired and refinished as if the damage was never there.

  • How do I maintain my GRP garage door?

    GRP garage doors are easy to maintain and only require a regular wash down with clean water to keep them in good shape. Don’t use abrasive, acidic or caustic cleaners on your door as this can damage the surface. If you have a gloss door, you can also enhance the shine using a fine polishing paste or ‘T-Cut’. As with any garage door, we recommend having your garage door serviced at least once a year to keep it well maintained.

  • Can you paint GRP garage doors?

    If you decide you want to switch up the colour of your garage door, it’s possible to repaint it and both gloss and wood effect finishes can be repainted, although you’ll lose the strained effect of a woodgrain door if you choose to do this. You’ll need a primer and topcoat paint that’s suitable for GRP materials and if you have a woodgrain effect door, you’ll need to remove the original staining using acetone. Gloss doors will need cleaning with an appropriate de-greaser before you can prime and paint them.

  • How much do GRP garage doors cost?

    While GRP doors offer a premium look and performance, they are actually a more affordable option compared to some other materials. Fibreglass is cheaper than wood and can be a competitive solution for steel doors too, as well as being a long-lasting option that makes them a cost-effective choice. And since GRP is very energy efficient, it can also help to lower your utility bills too. The price of the door itself varies depending on the manufacturer, style and size of door you choose – get in touch for a quote.

  • What colours are available for GRP garage doors?

    GRP doors come in a wide range of colours, finishes and woodgrain effects, and can be colour matched to tie in with the trim on window frames and other features of your home for a cohesive look. GRP doors can be manufactured in any RAL colours so if you don’t see a colour you like, you can request for your door to be produced in a colour that suits you.
