Local housing and a new front or back door
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.
These patterns matter for a new front or back door: older walls, roofs and floors in Mitcham can need different materials or extra preparation compared with newer homes.
Permissions for a new front or back door in Mitcham
Mitcham is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we 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.
From survey to handover
A visit to your home
First, someone visits your home in Mitcham to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Quote in writing
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Booking the work
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
The work itself
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Common questions
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
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.
Can you combine a new front or back door with other work?
Yes. Because we manage several trades under one contract, we can plan a new front or back door alongside other work on your Mitcham home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same 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.
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.
