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.
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.
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.
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 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.
A simple three‑step process that takes you from first survey to finished installation, with clear communication and costs at every stage.
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.
Posted on Jane PetrieTrustindex verifies that the original source of the review is Google. Linus and his team were excellent. No problem recommending them, they were nice people, clear, easy to deal with, patient with the process throughout and finished everything to a very high standard. They steered us through informatively from start to finish and also tidied up after themselves each evening which we really appreciated.Posted on Justin van RhynTrustindex verifies that the original source of the review is Google. We ordered a number of Velfac windows and doors for supply + installation through Citi Homes Windows. The service was excellent from start to finish - very good communication through the design process and we've been very happy with the installation as well. Linas in particular was a star - super responsive, patient as we made changes, and a pleasure to work with. Highly recommend.Posted on ed goddenTrustindex verifies that the original source of the review is Google. Outstanding service from start to finish. Linas and teams' clear communication and happy to help support throughout, made our windows and back door installation completely stress-free. Even had a site visit post-installation to check we were entirely satisfied with the works and service...which we are. Highly recommend. Many thanksPosted on Michael ScorerTrustindex verifies that the original source of the review is Google. This is a very special building company. I've worked in housing for 30 years and everything I experienced about Citi Homes is best in class. From first contact, communication was quick, clear and high quality. Quotes arrived quickly with high quality cad drawings. Once the detailed design was agreed, a delivery and installation date was agreed and then met. The operatives who fitted all eight windows in two days (bearing in mind the new windows were a completely different design to the ones removed) were polite, extremely conscientious about minimising any damage, very professional, clean and tidy. The result is a great product, perfectly and quickly installed. I have been recommending this company to friends and colleagues. If you need new high quality windows, at a highly competitive price, look no further. I would always recommend getting two or three estimates, but I honestly think that would be for reassurance rather than as a serious competitor to Citi Homes.Posted on thomas humphriesTrustindex verifies that the original source of the review is Google. Citi Homes supplied new Rationel windows for our loft conversion. Great service throughout - good support through the quotation / ordering process and excellent communication on delivery times etc once the order was placed.Posted on Justin EarreyTrustindex verifies that the original source of the review is Google. Citi replaced my damaged Velfac balcony door: Great communication from Linas who managed to source a replacement from the manufacturers, even though the door is no longer produced. The install team also did a great job delivering and troubleshooting on site to ensure the door was replaced and now fully usable. Highly recommend.Posted on Mary ThumTrustindex verifies that the original source of the review is Google. Citi supplied a very large (2 metres X 2 metres) window to replace one that had shattered. The job involved craning the new unit up to our fourth-floor terrace and fixing it in position. Citi found a very good crane company to do the lift and dealt with our local council to get the necessary license to close the street during the work. We found Linas, the Citi manager who ran our job, to be very professional and easy to work with.Posted on dermot hayesTrustindex verifies that the original source of the review is Google. I spent an enormous amount of time researching doors and windows. I wanted triple glazed, thin elegant frames, affordability and value for money. I searched the net and contacted very many companies; some looked very good indeed apart from the affordability and some were not worth bothering about. I contacted Velfac UK who I had heard were very good and they put me on to Citi Homes Windows who handle their products. We went to visit the Citi Homes showroom and they were fantastic. Over a cup of tea we discussed with them what we wanted and they showed me frames that exactly fitted the brief. They were able to give me an estimate on the spot, based on approximate sizes and followed up with a visit to discuss the project with my builder and to take accurate measurements. They confirmed the price and we placed the order just before Christmas 2025, taking delivery in the middle of March 2026, about eight weeks turnaround if you take out the Christmas period. The windows and doors are installed and I am delighted with them. They are substantial and elegant frames of excellent quality. The fitters were great and very charming; in fact all the people at City Homes are very charming and excellent communicators which really helps. I think the doors and windows are of excellent value and I got exactly what I wanted; triple glazed, thin elegant frames, affordability and value for money. The total price including fitting was under £8000.00. I would certainly highly recommend them. Dermot Hayes.Posted on Rosie GastonTrustindex verifies that the original source of the review is Google. Wonderful experience with the team from start to finish. They replaced 5 floor to ceiling window panels for us after damage caused by a fire. The installation and service was seamless. Great communication, constant updates on progress, and the guys were super efficient, hard working, respectful and tidy. They’ve done a fab job and we couldn’t be happier with both the process and the final product. Thank you!Posted on Philip WareTrustindex verifies that the original source of the review is Google. Excellent service from the Citi Homes Windows Team. Very helpful and competative with their prices. We would have no hesitation in using them again on any future projects.
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.
We supply and install. Every door comes with full professional installation by our own teams across London.
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.
