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.
Addresses across DA1 fall within our coverage for a new front or back door, so if your home is in Dartford we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £1,100–£3,900 including VAT before that visit.

What are homes like around Dartford?
Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.
One of England's sunnier, drier counties, but Thanet and the coast are windy, and Weald and London Clay soils can shrink in summer.
Whatever era your Dartford home dates from, we plan a new front or back door around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Dartford
For anyone in Dartford, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
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
Free site survey
A free survey comes first. It gives us what we need to price a new front or back door properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Your fixed price
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.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new front or back door are in place before the first day on site.
Build and hand over
Our trades complete a new front or back door while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

Questions about a new front or back door in Dartford
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.
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 much will a new front or back door cost in Dartford?
As a guide, expect to pay £1,100–£3,900 including VAT for a new front or back door in Dartford. That range is adjusted for the South East, which runs about 12% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
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.
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.
