Doors for London Homes

The door you choose affects how your home looks from the street, how secure it feels at night, how warm it stays in winter, and how much of the outside world you can invite in on a summer afternoon.

We supply and install doors across London, front doors, back doors, composite doors, bifold doors, sliding doors, French doors, patio doors, garage doors, security doors, and more.

We help you find the right door for every opening in your home.

What a good door actually does

A well-chosen door does several things at once.

Your front door is your home’s first impression and its first line of security. Modern composite doors and aluminium entrance doors fitted with multi-point locking and PAS 24 certification are among the most secure residential doors available today. A well-sealed external door also makes a real difference to how warm your home feels in winter — particularly in older London properties where doors and windows together account for a significant share of heat loss.

At the back of the house, the right door transforms how you live. Bifold doors and aluminium sliding doors open up the rear of a home in a way that creates a genuine connection between inside and outside — and once you have experienced a kitchen that flows directly into a garden as one continuous space, that connection stays with you.

Door Types

Every home is different, and so is every opening. Whether you are replacing a tired front door, opening up the back of the house or looking for something entirely bespoke, the right door type makes all the difference to how a space looks and feels.

Your front door sets the tone for the whole property, and your back door takes the most daily use of any door in the house. Both are available in composite, aluminium, and bespoke timber, in styles that suit period and contemporary London properties alike.

Aluminium sliding doors give you a wall of glass across the rear of your home, with slim thermally broken frames and large uninterrupted panes that maximise light and views into the garden. 

Aluminium bifold doors fold the whole rear wall back into a neat stack, opening up to 90–95% of the full aperture and connecting your living space to the garden as one continuous room. 

A pair of full-height glazed hinged doors that open outward or inward onto a garden or terrace, bringing in a wide flood of natural light and creating a proper threshold between the house and outside.

Sliding patio doors give you a clean, practical opening between your living space and garden in a simple two-panel format.

Steel-look aluminium Crittall doors bring the distinctive black grid aesthetic to both internal and external openings.

A pivot door swings on a top and bottom pivot point rather than side hinges, making it possible to create oversized, architecturally dramatic entrance doors in aluminium or bespoke timber.

Security doors are designed to maximise front door security, with reinforced frames, PAS 24–rated multi‑point locking and hardware tested to resist common burglary techniques.

Garage doors play a big part in your home’s kerb appeal and security, and modern sectional and roller designs open vertically so you can park right up to them without losing driveway space.

Door materials

Choosing a door material is really about priorities, security and low maintenance, architectural precision and slim sightlines, or the warmth and character that only real timber can give. Each of the three materials we work with has clear strengths and a natural fit.

Composite doors combine a solid insulated core, a tough GRP skin and multi‑point locking to deliver strong security, excellent thermal efficiency and long‑lasting colour stability.

Aluminium is the material that makes large, slim-framed sliding doors, bifold doors, aluminium French doors, aluminium entrance doors and pivot doors possible. The frames are narrow, the spans are wide, and every system is thermally broken to keep heat on the right side of the frame. 

The weight, the grain, and the feel of a well-made wooden door are genuinely its own thing. Timber doors, including timber French doors, bespoke timber doors, and wooden entrance doors, are made to order by specialist joiners using sustainably sourced hardwoods and softwoods, finished in any paint or stain.

The brands we work with

Glazing Options

The glass inside a door does just as much work as the frame around it.

  • Double glazed doors – standard across the full range, meeting current UK Part L thermal requirements and the right choice for most door positions in the home.

  • Triple glazing – worth considering for exposed positions, north-facing openings or large glazed doors where extra insulation makes a noticeable difference to comfort.

  • Acoustic laminated glass – significantly reduces the intrusion of traffic, rail and street noise; a sensible upgrade for any door that faces a busy road or sits close to a railway line.

Most people think about the frame and the style first, which makes sense — but the glazing specification is what determines how well a door actually performs day to day. A well-glazed door keeps the warmth in, keeps the noise out, and stays comfortable to sit near even in the depths of winter. We advise on the right glazing for every door we install, based on the position, orientation, and what the door needs to do.

How We Work

A simple three‑step process that takes you from first survey to finished installation, with clear communication and costs at every stage.

  • Survey. We visit your property, measure the openings, look at the structure and talk through what you want to achieve.

  • Design and specify. We put together a clear specification covering material, system, glazing, hardware, colour and an itemised price.

  • Supply and install. We source doors from trusted manufacturers and install them across London, with every job signed off to current building regulation standards.

Getting the right door is one thing; having it fitted properly is what makes the difference in the long run. Working with an experienced, FENSA-registered installer means your door is certified to current UK building regulations, comes with an insurance-backed guarantee, and is fully documented if you ever come to sell your home.

FAQ

Composite doors combine a solid insulated core with a GRP outer skin that holds its colour and finish through all weathers with minimal upkeep. Wooden entrance doors and exterior wood front doors are made from real timber, more character, more individuality and more scope for bespoke work, with periodic painting or staining to keep them in top condition. For most London front door replacements, composite is the practical choice. For conservation areas, listed buildings or a genuinely one-off entrance, timber is where we start.

Bifold doors fold back to leave up to 90–95% of the aperture completely clear. Aluminium sliding doors open around half the width, with the other half as a fixed panel, meaning larger, uninterrupted panes of glass and a very clean look when closed. Both are excellent. Bifold gives you the widest possible opening; sliding gives you maximum glass and a minimal frame.

French doors are hinged and open inward or outward — classic, elegant and well-suited to both period and contemporary London homes. Patio doors come in two formats: sliding patio doors that run along a track and keep the full ground area in front clear, or outward-opening patio doors that swing like French doors but with a simpler, more understated frame. Both are a practical choice for smaller gardens and terraces where every metre of outdoor space matters.

Timber is almost always the right answer. Planning authorities in conservation areas and for listed buildings typically require materials that match the original character of the property, and a well-made timber door does that more convincingly than any other option. We supply bespoke timber doors to order that satisfy planning requirements while incorporating modern draught sealing and double glazing where permitted.

Bifold doors and sliding doors are both popular choices for kitchen-to-garden openings, and the right one depends on how much of the opening you want to use. Bifold doors fold the whole wall back to give you a near-full-width opening; ideal if you want inside and outside to feel like one continuous space. Sliding doors keep more glass in view when closed and suit spaces where a clean, minimal frame matters more than the widest possible opening. French doors are a strong third option for smaller openings or period properties where the hinged, classic look fits the character of the room better.

Crittall and Crittall-style doors are just as popular inside the home as they are on external openings. The slim black frames and large glass panels are particularly effective for separating spaces without blocking light, dividing a kitchen from a dining area, creating a home office that feels enclosed without feeling shut off, or adding a glazed partition between a hallway and a living room. In open-plan London homes where people want to zone spaces without losing the sense of space and light, a Crittall-style internal door or screen is one of the most effective ways to do it.

It depends on the material, the size, the style and the glazing. A composite back door and a triple-glazed aluminium bifold system are very different in scope and price. Contact us and we will put together a clear, itemised quote based on exactly what you need.
