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.
We handle bifold or sliding doors as a managed project across Renfrewshire and Inverclyde: one contract, one contact, and trades working to an agreed specification. Coverage includes Paisley, Greenock, Newton Mearns and Renfrew and their surroundings. In Scotland the consent rules have their own details, which we check for you. Typical prices in Scotland fall within £2,900–£7,700, VAT included, and are fixed in writing after a survey.

Homes in Renfrewshire and Inverclyde
Paisley has sandstone tenements and terraces from its textile era, Greenock and Port Glasgow have tenements and housing climbing the hills above the Clyde, and Gourock and Kilmacolm have Victorian villas. Post-war estates and newer private housing surround the towns, and roughcast is a common finish.
Roughcast and tenement buildings commonly need re-rendering, window replacement and roof work. Villas suit kitchen extensions and landscaping, and semis often take loft conversions and driveways.
Inverclyde is one of the wettest parts of lowland Scotland, and homes facing the Firth of Clyde take wind and driving rain.
Do you need permission in Renfrewshire and Inverclyde?
Because Renfrewshire and Inverclyde falls under Scotland's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
In Scotland, replacing windows and doors on a house generally needs no planning permission when the style is similar, but listed buildings and conservation areas are closely controlled and often need consent for any change of material or pattern.
A building warrant is not usually needed for like-for-like replacement windows, but the new units must still meet the Scottish building standards, including energy performance and, where relevant, escape from upper floors.
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
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for bifold or sliding doors, and photograph or measure anything the quote needs to reflect.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for bifold or sliding doors.
Dates and permissions
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
How we work
Frequently asked questions
Can you combine bifold or sliding doors with other work?
Yes. Because we manage several trades under one contract, we can plan bifold or sliding doors alongside other work on your Renfrewshire and Inverclyde 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.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from bifold or sliding doors, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
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.
Should I choose bifold or sliding doors?
Bifold doors suit you if you want to open the whole width to the garden, because the panels fold and stack to one side. Sliding doors suit you if you mainly want the view, because they have fewer, larger panes and slimmer frames, though only part of the width opens. Sliding doors also take up no room when open. We help you weigh up how you will use the space in summer and winter.
