uPVC Door Installation

Our uPVC door installation service covers front doors, back doors, French doors, patio doors, sliding doors and bifold doors.

Every door is measured and made for your home, not forced into it. We take out the old door, fit the new frame, then seal and align it carefully. Before we leave, we check the locks, the drainage and how the door actually opens and closes, because that’s the bit you’ll notice every day.

uPVC Door Fitters

A badly fitted door causes real headaches. It can drop, catch on the frame, let water in, or put strain on the locks until they give up. That’s why our uPVC door fitters sweat the small stuff. The result is a door that closes smoothly and keeps doing it for years.

You get a free survey, a clear written quote and a proper installation, with no pressure.

Our uPVC Door Range

uPVC Front Doors

Your front door is the first thing people see, and the one you rely on most for security. uPVC front doors give you a smart, durable entrance with very little upkeep: no sanding, no repainting and no swelling in wet weather. Choose from a range of colours, woodgrain finishes, decorative glass for privacy, and matching handles and locks. We’ll help you pick a style that suits your property.

uPVC Back Doors

A back door works hard. It’s opened with muddy boots, shopping bags and kids running in and out. uPVC back doors are a practical choice because they’re tough, easy to clean and well insulated, so your kitchen or utility room stays warmer.

We can replace a tired back door with a secure, made-to-measure one, with glazing options if you want more light, or a more solid design if you’d like extra privacy.

uPVC French Doors

uPVC Bifold Doors

uPVC bifold doors fold back neatly to open up a wide gap between your house and garden. They work brilliantly in kitchens, extensions and open-plan spaces, especially when the sun’s out.

At your free survey, we’ll look at your opening, access and the way you use the space. Then we’ll suggest the panel layout that makes the most sense for you.

uPVC Patio Doors

uPVC patio doors slide along a track instead of swinging open, which makes them a smart choice when space is tight. You get wide, clear views of the garden, and they suit kitchens, conservatories and rear extensions.

Got an old, sticky sliding door? We can swap it out, or fit a brand-new patio door as part of a bigger glazing upgrade.

Replacement uPVC Doors

Is your door draughty, warped, hard to lock, or always needing another fix? A replacement uPVC door may be the better long-term move. We can replace old uPVC front doors and back doors, tired timber doors, and damaged patio or French doors with modern, energy-efficient options.

Before we suggest replacing anything, we’ll always check whether a repair could solve the problem. We’d rather be honest than sell you something you don’t need.

uPVC Door Repairs Near You

Looking for uPVC door repairs near me in South London or Surrey? We can help with:

Doors that won’t close or lock properly
Doors that have dropped or gone out of alignment
Faulty multipoint locking mechanisms
Broken or stiff handles
Worn hinges, seals and keeps
Sticking patio, French or bifold doors

If your door is otherwise in good shape, a repair is often quicker and cheaper than replacing it.

uPVC Door Lock Repairs and Replacement

A door that won’t lock properly is more than annoying. It can leave your home less secure. Our uPVC door lock repairs cover faulty multipoint mechanisms, worn cylinders, misaligned keeps and stiff handles.

Most uPVC doors use a multipoint lock, where several bolts and hooks engage along the frame when you lift the handle and turn the key. If the door drops by even a couple of millimetres, those points stop lining up, and a good lock can feel stiff or refuse to turn. That’s why we check alignment first. Often it’s a simple adjustment, not a new lock.

If the mechanism has packed up completely, we can arrange a uPVC door lock replacement and upgrade the cylinder where it’s needed. We’ll also check the door’s alignment so the same problem doesn’t come back a few months later.

Replace Handle on uPVC Door

Need to replace a handle on a uPVC door? We’ll do that, and check the spindle, fixing screws and locking mechanism while we’re there.

Handles come in different sizes, fixing centres and spindle lengths. So we match the new one to your existing door instead of fitting a generic part and hoping for the best.

Doing it yourself? The basic steps are:

Open the small cover on the handle’s base to reveal the screws.
Undo the screws and lift off the old handle.
Check the new handle’s spindle length and screw spacing match the old one.
Fit the new handle, tighten the screws and test it with the door open.

If it still feels stiff or won’t lift smoothly, the fault is usually inside the lock. Give us a call and we’ll take a look.

What Our Customers Says About Us

uPVC Doors - FAQs

How much do uPVC doors cost in South London and Surrey?

It depends on the door style, size, glazing, colour, hardware and what the installation involves. A standard replacement back door usually costs less than French, patio or bifold doors. The easiest way to get an accurate price is a free survey and written quote.

Are uPVC front doors secure?

Yes. Most modern uPVC front doors have a multipoint locking system, which holds the door shut at several points along the frame. To keep things secure, choose a good-quality cylinder and sort out worn locks, handles or misaligned parts quickly.

Can you replace uPVC back doors as well as front doors?

Yes. We supply and fit both, made to measure, with a choice of colours, finishes and glazing.

Can you repair a uPVC door instead of replacing it?

Often, yes. Faulty locks, loose handles, doors that have dropped, worn hinges and damaged seals can usually be repaired. You’d normally only need a replacement if the frame is warped, cracked or badly damaged.

Why is my uPVC door not locking properly?

The usual suspects are a door that’s dropped slightly, keeps that no longer line up, a worn multipoint mechanism, a faulty cylinder or a stiff handle. A professional can tell you whether it needs realigning, a lock repair or a full replacement.

Can you replace just the handle on a uPVC door?

Yes. We match the handle to your door’s size and spindle, then check the lock behind it works smoothly.

Will I get a certificate for my new door?

Yes. As a FENSA-registered installer, we provide a certificate on completion. Keep it safe, because buyers’ solicitors often ask for it.

What is the difference between uPVC French, patio and bifold doors?

French doors have two hinged panels that swing open. Patio doors slide sideways along a track. Bifold doors have several panels that fold back to give you a wide opening. The right one depends on your space, your budget and how much garden access you’d like.
