Practical uPVC back doors in Luton, St Albans, Cambridge and Bedford

As uPVC offers excellent resistance against discolouration and warping, it’s great for anyone looking for a durable back door option. However, uPVC is also super easy to clean, so maintenance times are low with them. Combining great natural insulation qualities with multiple heat-trapping chambers, uPVC back doors are some of the most efficient of their kind too.

We offer white uPVC back doors which are always a hit with homeowners. However, stylish woodgrain finishes are available too, for doors that look just like wood but offer all the practical qualities of uPVC. There's also a huge range of alternative colour options available, including pebble grey, sage smooth and claystone.

In addition to standard entrance doors, we can also fit uPVC French and patio doors to the back of your home.

Modern aluminium back doors in Market Harborough, Peterborough, Banbury and Dunstable

As a super-sturdy material, aluminium is perfect for creating robust and secure back doors. Plus it won’t corrode, so you can expect aluminium back doors to last for a very long time. Aluminium back doors are also thermally broken, which means that insulating materials are fitted within their frames to keep your house warm. Aluminium doors are also known for their slimline frames, resulting in larger areas of glass. For this reason, they're a great way to bring the outside into your home also.

Along with aluminium back entrance doors, we’ve got sleek and slender sliding patio and bifold doors to choose from. Both options are a great way to flood the back of your home with light whilst keeping it secure. Plus, our aluminium door options come in over 200 RAL colours, so adapting their look to suit any home is no trouble at all.

Wonderful wooden back doors that can last a lifetime

It’s hard to beat wooden back doors in terms of beauty, although they’re exceptionally practical too. They make full use of timber’s excellent natural insulation and durability, leaving homeowners with a warm home and a back door that can last a lifetime. Contrary to popular belief, they also require little in the way upkeep; simply wipe them down occasionally with a soft cloth and retreat them every 6-8 years and that’s all you need to do with them.

They’re available in a superb selection of opaque and paint finishes, so there is a wealth of looks that you can achieve. Style wise, there are plenty of choices too; choose from timber entrance, patio, bifold, French, tilt & slide, and stable doors.

Are solid wood doors worth it?

Double glazed back doors for a warm and secure home

If you’re opting for a set of French, bifold or sliding patio doors, no matter whether they’re built from uPVC, aluminium or timber, they all come equipped with high-quality double glazing as standard. Therefore, they offer excellent heat retention, leaving you with a home that is brighter lit than before without having to sacrifice any warmth. Toughened glass, which is heavily compressed, making it much harder to break than standard glass, is also used on these types of doors, for security and safety.
