Aesthetic Appeal

GreenCastle doors come in a range of styles and finishes that can improve the appearance of any home, traditional or modern. If you want a door with a more classic aesthetic appeal, a composite door may be a good choice.

UPVC doors usually cost a lot less than timber doors, and they require less upkeep to maintain durability. In general, wooden doors are at the higher end of the price spectrum, while uPVC doors are more affordable than any other type of door.

Cost Effectiveness

As well as being affordable, our doors are also good value for money. When you upgrade to a uPVC or composite door, it’s a long-lasting investment in your home. 

With no expensive maintenance, your door will retain shape, size and colour, and continue to look as good as new for many years.

Longevity and Durability

UPVC doors and composite doors are both made with tough materials designed to stand the test of time. 

 UPVC doors last on average 20 to 25 years. Composite doors will serve you well for around 30 years. Both types of doors are weatherproof and resist rotting, warping, and cracking.

Easy Maintenance and Cleaning

Unlike timber doors, uPVC doors and composite doors are low maintenance. You won’t have to worry about continually repainting and varnishing your door. 

Just use water and a mild detergent to wipe the door down with a soft cloth or sponge from time to time. This will prolong the life of your door as well as keep it looking its best.

Property Value Boost

The additional kerb appeal of a GreenCastle front door won’t just catch the attention of your neighbours. If you put your house on the market, it will be the first thing a potential buyer will notice as they approach your property. 

When your front door creates a good first impression before a buyer steps over the threshold, they’ll be primed to appreciate the selling points of the interior of your home. And this can potentially get you a better price for your property.

Door Style Options

GreenCastle’s Edinburgh door installation services offer a wide variety of choice when it comes to design styles and finishes and door panel and glazing panel configurations. So your main entrance door will complement your house frontage with an attractive focal point, whether you have a traditional or modern home.

Classic Style 

Our classically styled doors will enhance any home. Perfect for older properties, they also add a feel of timeless sophistication to a contemporary home. 


Cottage Style

With a warm and cosy feel, our cottage-style doors look just as good in urban homes as they do in the delightful villages around Edinburgh.


Modern Style

Our modern-style doors, with a high-grade stainless-steel trim, are the perfect choice for many contemporary homes.


Contemporary Bohemian

Combined with modern glazing, bold colours, and stainless-steel hardware, doors from our Contemporary Bohemian range make a strong design statement.

Bifold, Patio, and French Doors

Besides front doors, GreenCastle offers a range of other equally attractive and secure uPVC or composite exterior doors. These include bifold doors, patio and balcony doors, and French doors.

Bifold Doors

Our bifold doors can give your home the wow factor while making good use of available interior space.

They will fit in tight areas where other types of doors aren’t practical. This is because bifold doors work on a concertina principle, folding back into a compact area. Our bifold doors blend with both traditional and contemporary homes and will flood your interior with natural light.

Sliding Patio Doors and Balcony Doors

Like bifold doors, our sliding patio and balcony doors will give you an uninterrupted view of your surroundings while allowing a lot of daylight into your home.

Sliding doors take up even less space than a bifold door because they don’t project outwards. And you can enjoy the outside view throughout the year – our sliding patio doors, like bifold doors, exclude draughts and reduce heat loss.

French Doors

French doors typically consist of a pair of doors with glass panes extending most of their length.

They add a stylish elegance to home interiors and exteriors and provide an unobstructed view of your outside space and beyond. French doors also make access to your home easier if you have a large pram, for instance, or when you’re having bulky items delivered.

UPVC doors are made from the rigid plastic of unplasticized polyvinyl chloride, which can be combined with steel. Composite doors combine steel-reinforced uPVC with materials such as glass-reinforced plastic and solid timber. It’s the more complex manufacturing process of composite doors that makes them more expensive than uPVC doors.

While wooden doors are prone to fading and discoloration with prolonged exposure to the sun, a uPVC door or composite door will maintain its colour through the years. Because they resist UV (ultraviolet) sun rays, they will continue looking as good as the day they were installed.

Our doors are competitively priced and represent a solid investment in your property. Door prices vary depending on factors such as size, design, and colour. UPVC doors are more affordable than composite doors, but composite doors are made with stronger materials.
