Bifold doors are glazed panels that fold and stack to one side to open up a wide gap, while sliding doors glide past each other on tracks; both connect a living space to the garden and bring in more daylight.

Housing across Northumberland
Stone dominates rural Northumberland, from sandstone farmhouses and villages to fortified bastle houses in the uplands. Alnwick, Hexham and Morpeth have historic stone centres, Berwick has Georgian streets, and south-east towns such as Ashington, Blyth and Bedlington have colliery terraces. Cramlington grew from the 1960s with planned estates.
Stone homes often need lime pointing, roof slating and breathable render. Colliery terraces suit loft conversions and rear extensions, and estate homes commonly take garage conversions and window upgrades.
The coast is exposed to cold North Sea winds, and the Cheviots and higher moorland see snow and hard frosts in winter.
Do you need permission in Northumberland?
Northumberland 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.

How we work
Questions about bifold or sliding doors in Northumberland
Are bifold doors secure?
Modern bifold and sliding doors are designed to be secure, with multi-point locks, shoot bolts into the frame, internally beaded glass and toughened or laminated glazing. The traffic door, which you use day to day, has a cylinder lock that can take an anti-snap barrel. Sliding doors also have anti-lift features. We explain the locking on each option so you can compare like for like.
Do I need planning permission in Northumberland?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Northumberland is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
How much will bifold or sliding doors cost in Northumberland?
As a guide, expect to pay £2,700–£7,200 including VAT for bifold or sliding doors in Northumberland. That range is adjusted for the North East, which runs about 10% below 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 you fit bifold doors where I have a window now?
Bifold doors can usually replace a window by cutting the wall down to floor level and, if the opening is being widened, fitting a new lintel or steel beam. A structural engineer sizes the beam, and building control approval is needed. Radiators, pipes and cables under the window may need moving. We check all of this at the survey and include it in a single written quote.
How do I maintain bifold doors?
Bifold doors need simple, regular care to keep them running smoothly. Vacuum or brush grit out of the bottom track every few weeks, wipe the frames with warm soapy water and avoid abrasive cleaners. Once or twice a year, lubricate the rollers, hinges and locks with a silicone spray. If the panels start to drop or catch, the hinges can usually be adjusted rather than replaced.
