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 Brentwood, as anywhere in Essex, the price of a new front or back door is driven mainly by size, materials and access. Across the East of England our guide sits at £1,050–£3,700 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.

Homes in Essex
Essex ranges from timber-framed and weatherboarded cottages in the north, some with decorative pargeting, to Victorian terraces in Colchester, Chelmsford and Southend. Basildon and Harlow were built as post-war new towns, much of the south-east has interwar suburbs and bungalows, and large new estates continue to appear around Chelmsford and Braintree.
Terraces and semis commonly suit loft conversions and rear extensions, and many bungalows can take a loft room. New-town homes often need cladding, window and roofline renewal, while timber-framed cottages call for lime plaster and repairs that respect the original frame.
None of this holds for every street in Brentwood, which is why we look at your actual house before pricing a new front or back door rather than assuming from its age alone.
Planning and building rules in Brentwood
Homes in Brentwood come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
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.
How does the job run?
Survey and measure
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Price and scope agreed
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
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Brentwood property.
Build and hand over
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Front and back doors in Brentwood: 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.
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 does it take to make a new door?
Made-to-measure doors usually take a few weeks to manufacture after the survey and your order are confirmed. Bespoke colours, special glass designs and aluminium doors can take longer. Once the door arrives, we arrange a fitting date that suits you. We give you a realistic lead time with your written quote, and we keep you updated if the manufacturer's dates change.
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 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.
