External Doors London, Get A Quote

London homeowners trust London Window Company to supply and fit external doors that look good, last well, and keep their properties secure. We cover all areas across London and the surrounding counties, and our fitting teams work on everything from Victorian terraces to modern new builds.

A new external door does a lot of work. It has to handle the weather, deter intruders, hold in heat, and make a good first impression every single day. Getting the right door fitted properly makes a real difference to how your home looks and feels.

What external doors do you offer?

Composite doors are our most popular choice for front doors in London. They have a solid timber core wrapped in a tough GRP skin, which means they hold their shape and colour for years without warping, swelling, or needing a repaint. Security is built in as standard, with multi-point locking, anti-snap cylinders, and reinforced frames.

uPVC external doors are a solid option for back doors, side entrances, or anywhere you want strong performance without a high price. They come in a wide range of colours and finishes, and every uPVC door we fit includes multi-point locking as standard. French doors are also available if you want a wide opening out to a garden or patio, with low thresholds and locking on both leaves.

If you want to make more of your entrance, external doors with side panels are worth considering. Side panels bring natural light into your hallway and give the whole frontage a more open, generous feel. You can choose from clear, frosted, or decorative glazing to suit the style of your home.

How energy efficient are your external doors?

All our external doors are fitted with insulated cores and double glazed glass units where applicable. This helps reduce heat loss through the door itself, which makes a noticeable difference in hallways that tend to feel cold in winter. Composite doors in particular perform very well on thermal efficiency because of the foam-filled core.

Our doors are rated to current energy performance standards, so you can be confident you are getting a door that meets modern requirements rather than something that just looks the part.

How secure are the doors you fit?

Security is taken seriously on every door we install. Here is what comes as standard on our external doors:

• Multi-point locking on every external door, engaging at several points along the frame rather than just a single bolt
• Anti-snap, anti-pick cylinders designed to resist the most common forced entry techniques used by burglars
• Reinforced steel frames that resist physical attack and do not flex under pressure
• Toughened or laminated glass where glazing is included, making the panels far harder to break
• Shootbolts and hook locks built into the mechanism on French doors and doors with side panels
• PAS 24 rated products available across our composite door range, meeting the enhanced security performance standard

If you have specific security concerns about your property, just mention them when you call. Our team can point you towards the most suitable door and locking options for your situation.

How long does fitting an external door take?

Most single external door installations are completed in a single day. Our fitters arrive in the morning, remove your old door and frame, fit the new one, adjust and test the locking mechanism, and leave everything clean and tidy before they go. You will have a fully working, secure door by the end of the day.

French doors or doors with side panels may take a little longer depending on the size of the opening and whether any structural work is needed. Your surveyor will let you know exactly what to expect before any work begins.

What guarantee do I get with a new external door?

Every external door we supply and fit comes with a full 10-year guarantee covering both the product and the workmanship. That covers the door, the frame, the glazing units, and the locking hardware. If anything is not right, we come back and sort it. No arguments, no extra charges.

The guarantee is registered to your property, so it is not something that disappears if a fitter moves on. You have that cover in writing from day one.
