A replacement front or back door is a new door and frame, usually composite, uPVC or aluminium, made to fit your existing opening and fitted with multi-point locks and weather seals to improve security, warmth and kerb appeal.
In Pinner, as anywhere in London, the price of a new front or back door is driven mainly by size, materials and access. Across London our guide sits at £1,300–£4,600 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

What are homes like around Pinner?
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
Knowing the typical building types in London helps, but a survey of your own home in Pinner is what decides the right approach to a new front or back door.
Planning and building rules in Pinner
As Pinner is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.
Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

Common questions
What is the difference between a composite and a uPVC door?
A composite door has a tough outer skin over a solid insulated core, so it feels heavier and more solid than uPVC and holds its colour well. A uPVC door is built from reinforced plastic panels and costs less. Both can have multi-point locking and good weather seals. Many people choose composite for the front door and uPVC for back or side doors, where looks matter less.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How much does a new front door cost?
A new front door costs £1,300–£4,600 supplied and fitted, depending on the material, the amount of glass and whether you want side panels. A uPVC back door sits at the lower end, a composite front door in the middle, and aluminium doors or doors with side panels at the top. Locks, letterplates and dual colours also affect the figure. We confirm a fixed price in writing after measuring your opening.
How long will a new front or back door take?
On a typical home, allow Usually half a day to one day per door. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
How do I look after a composite or uPVC door?
Looking after a composite or uPVC door is mostly a matter of regular cleaning with warm soapy water and a soft cloth. Avoid solvents and abrasive pads, which can dull the finish. Once or twice a year, lightly oil the lock mechanism and the moving parts along the edge of the door, and check the seals. If the door starts to catch, the hinges can usually be adjusted easily.
