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.
Every house in Marlow is a little different, so we never price a new front or back door from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in the South East should budget £1,100–£3,900 including VAT, with work typically taking Usually half a day to one day per door.

What should you budget for a new front or back door in Marlow?
Here is how the guide price for a new front or back door breaks down in Marlow. We start from national figures and adjust for the South East, which comes out about 12% above the national guide. The resulting range, VAT included, is £1,100–£3,900, and a survey, at no cost to you, firms it up.
| Type of job | What it usually involves | Guide in Marlow |
|---|---|---|
| uPVC back door | A standard uPVC back or side door with a half-glazed panel and multi-point lock. | £900–£1,700 |
| Composite front door | A made-to-measure composite door in your chosen colour, glass design and hardware. | £1,350–£2,800 |
| Aluminium or door with side panels | A premium aluminium door, or a composite door with one or two side panels. | £2,800–£5,600 |
The main things that change the figure:
- Door material: uPVC, composite or aluminium
- Lock, cylinder and hardware specification
- Colour, including different colours inside and out
- Condition of the opening, threshold and surrounding brickwork

Building in Marlow
Buckinghamshire runs from Chiltern villages of brick and flint, through Metroland interwar semis around Amersham and Chesham, to Victorian terraces in High Wycombe and Aylesbury. Milton Keynes adds estates built from the 1970s onwards in brick, render and timber frame, and new housing continues to spread around its edges.
The Chiltern hills are more exposed than the vale below, and clay-with-flints soils make drainage design and footing depth worth checking early.
Building traditions across Buckinghamshire also raise conservation and planning questions, so we check those for a new front or back door in Marlow at the survey stage.
Permissions for a new front or back door in Marlow
The notes below cover England, which is where Marlow sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
From survey to handover
Free site survey
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new front or back door.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Front and back doors in Marlow: questions
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.
How long will my home be open while the door is fitted?
Fitting a new door usually takes half a day to a full day, and your home is only open for the short time between taking out the old frame and fixing the new one. We keep the opening covered if there is any delay, and we never leave a doorway insecure overnight. Once the frame is fixed, we hang the door, adjust the locks, seal around the frame and finish the trims.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new front or back door, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
How secure are modern doors?
Modern external doors are far more secure than older designs because they lock at several points along the frame, not just at the handle. We fit anti-snap cylinders, which resist a common method of forced entry, in reinforced frames. Laminated or toughened glass panels add further protection. For extra peace of mind you can add a door chain, a viewer or a smart lock, which we can include in your quote.
