Greenock Windows And Doors fit and supply composite doors across Greenock and the nearby towns of Gourock, Port Glasgow, and Inverclyde. If your front door is draughty, tired-looking, or just not doing its job properly, a composite door is worth serious consideration.
Composite doors have grown in popularity for good reason. They hold up well against the kind of wet, windy weather Greenock regularly sees, and they do it without needing much attention from you over the years.
What exactly is a composite door?
A composite door is built using several different materials layered together, each one doing a specific job. The outer skin is made from Glass Reinforced Plastic, often called GRP. It gives the door its solid feel and realistic wood grain finish, without any of the maintenance headaches that come with actual timber.
Inside that GRP shell sits either a solid timber frame or a dense foam core, depending on the construction. Both options deliver strong thermal performance and a door that does not flex, bow, or warp over time the way a traditional wooden door can.
What composite doors do you offer?
There is a wide range to choose from, and we will walk you through the options properly rather than just hand you a brochure and leave you to it. Styles include traditional panelled designs, cottage-style stable doors, and cleaner contemporary looks that suit newer builds.
Colours cover everything from classic white and black through to anthracite grey, rosewood, and a range of bold shades. You can also choose a dual colour finish, so the outside of the door is different from the inside. Hardware such as handles, knockers, numerals, and letter plates come in chrome, satin, black, and gold finishes to finish the door off properly.
How secure are composite doors?
Security is one of the main reasons homeowners in Greenock choose composite over other door types. Every composite door we fit comes with a multi-point locking system as standard. The cylinder fitted to the lock is anti-snap, anti-pick, and anti-bump, which covers the most common methods used in break-ins.
The GRP skin and solid core also mean the door itself is far harder to force than a hollow uPVC or thin timber door. On top of that, the door frame is fitted and sealed properly, so there are no weak points around the edges.
How energy efficient are they?
A composite door makes a noticeable difference to draughts and heat loss, particularly in older Greenock properties where the existing door may have gaps around the frame or a thin core. The insulating foam or solid timber centre keeps warmth in, and the door is fitted with quality weatherseals around the full perimeter.
Most composite doors we install achieve strong energy ratings, and when combined with a double glazed glass panel, they perform significantly better than a standard uPVC door of the same age.
How long does fitting take?
In most cases, fitting a composite door takes a single day. Our fitters will remove your old door, prepare the frame, fit the new door, and make sure everything is aligned, sealed, and working correctly before they leave. You will not be left with a gap overnight.
If structural work is needed around the frame, we will tell you upfront before any work begins. No surprises on the day.
What guarantee do I get?
Every composite door we supply and fit in Greenock comes backed by a manufacturer guarantee covering the door itself, along with a workmanship guarantee on the installation. The specific terms depend on the product chosen, and we will go through those clearly with you as part of your quote.
Key things covered as standard include:
- The GRP outer skin, which is guaranteed against fading, cracking, and peeling
- The locking mechanism, covered against mechanical failure under normal use
- The glazed panel, covered for any seal failure or misting between the panes
- The frame and threshold, covered against warping, splitting, or structural movement
- The installation itself, with our workmanship guarantee covering the fitting and sealing of the door
