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.
For a homeowner in Blackburn, planning a new front or back door tends to begin with two questions: what will it cost, and how disruptive will it be? Our guide range is £950–£3,300 including VAT, and a typical job runs to Usually half a day to one day per door. Both numbers firm up once we have seen the property, measured up and agreed exactly what is included.

Building in Blackburn
East Lancashire mill towns such as Burnley, Blackburn and Accrington have long rows of stone and brick terraces, while Preston is mostly red brick. Lancaster uses sandstone for its Georgian centre, Blackpool and the Fylde coast have guest-house terraces and many bungalows, and interwar and newer estates surround most towns.
Mill-town terraces commonly suit attic conversions, kitchen extensions and repointing. Bungalows on the coast often take loft rooms and porches, and stone properties may need lime pointing and roof repairs.
So when we survey a Blackburn property for a new front or back door, the first step is working out how it was built and what has been changed since.
Do you need permission in Blackburn?
As Blackburn 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.
The four stages
We look at the job
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.
Your fixed price
After the survey we send a quote for a new front or back door that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
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 Blackburn 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
Common questions
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.
Can I have a low threshold for wheelchair or pushchair access?
A low threshold is a flat or very shallow sill that makes a doorway easier to cross with a wheelchair, walking frame or pushchair. Most composite, uPVC and aluminium doors can be supplied with one. The outside ground level and drainage need checking, because a low threshold must still keep rainwater out. We look at this during the survey and suggest a channel drain or small ramp if needed.
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.
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.
