Our Front Doors Material

uPVC Back Doors

uPVC is the most popular choice for good reason. These doors are affordable, low-maintenance and a good all-rounder for thermal efficiency. They never need repainting, and a wipe with a damp cloth keeps them looking tidy.

Best for: Homeowners who want reliable performance and good value, and landlords who want a door that lasts without fuss.

Composite Back Doors

Composite doors are built from several layers of materials, usually a solid core with a tough outer skin. They look like timber but are designed to resist warping, fading and weathering. They’re typically heavier and more robust than uPVC, which many people like for security and insulation.

Best for: Anyone who wants a premium feel, strong security and a wide choice of colours and finishes.

Aluminium Back Doors

Aluminium frames are slim, strong and modern. They allow larger glass areas and clean, contemporary lines, which is why they’re a favourite for extensions, bifold-style openings and open-plan kitchens. They’re also long-lasting and don’t rot or warp.

Best for: Modern homes, extensions and anyone who wants maximum light and a sleek look.

Back Door Replacement vs. Repair: Which Do You Need?

Not every problem means a new door. Here’s a simple guide.

Repair may be enough if:

The lock or handle is stiff or worn
The door is dropping slightly and catching on the frame
The weather seals are tired and letting in draughts
A glass panel is cracked or the double-glazed unit has misted up
Hinges need adjusting or replacing

Replacement is usually the better choice if:

The frame is rotten, warped or structurally damaged
The door no longer closes or locks securely
You’re seeing persistent draughts, damp or condensation
Repair costs are approaching the price of a new door
The door is simply old and you want better security and insulation

We’ll always tell you honestly which route makes sense. If a repair will do the job, we’ll say so.

Back Door Repair Services

Small problems tend to get worse if left, so it’s worth sorting them early. Our repair work includes:

Back door repair

Locks, multipoint mechanisms, handles, hinges, letterboxes and weatherstrips. If your door is hard to lock or has started to sag, it’s often a quick and affordable fix.

Back door frame repair

Frames take a lot of punishment from weather, movement and age. We can assess whether the frame can be repaired or whether replacement is safer and more cost-effective.

Back door glass repair

A cracked pane or a unit that’s gone foggy between the layers affects both appearance and energy efficiency. We can replace the glass without changing the whole door in many cases.

What Our Customers Says About Us

Back Door - FAQs

How much does a new back door cost in South London and Surrey?

Price depends on the material, size, glazing and security features. As a general rule, uPVC is the most budget-friendly, composite sits in the middle to higher range, and aluminium is often the premium option. The best way to get an accurate figure is a free survey and written quote.

How long does back door installation take?

A standard back door replacement is often completed in a day, though this depends on the size of the opening and whether any frame or brickwork repairs are needed. We’ll give you a realistic timeframe when we quote.

Can you repair my back door instead of replacing it?

Often, yes. Problems like worn locks, dropped doors, tired seals and cracked or misted glass can usually be repaired. If the frame is badly damaged or rotten, replacement may be the safer long-term option. We’ll tell you honestly which makes more sense.

Which is better: composite, uPVC or aluminium?

It depends on what matters most to you. uPVC offers great value and low maintenance, composite offers a robust, premium feel, and aluminium gives slim sightlines and a modern look. We’ll talk through the pros and cons for your property.

Do I need planning permission to replace my back door?

In most cases, replacing a back door like-for-like doesn’t require planning permission. However, listed buildings, conservation areas and some flats or leasehold properties can have extra rules. It’s worth checking with your local council or freeholder if you’re unsure.

Why is my back door hard to lock or closing badly?

Common causes include dropped hinges, a misaligned lock keep, worn multipoint mechanisms or a warped frame. Many of these are fixable with adjustment or part replacement. If you notice it’s getting worse, get it checked before it becomes a security issue.

Can you replace just the glass in my back door?

In many cases, yes. If a pane is cracked or the double-glazed unit has misted up, the glass can often be replaced without changing the door itself.

Do you fit back doors for businesses?

Yes. We supply and fit commercial back doors for shops, offices, restaurants and other premises. Let us know your requirements, including security and access needs, and we’ll advise on suitable options.
