Newton Mearns Windows And Doors supply and fit patio doors for homes across Newton Mearns and the nearby areas. If you want to open up your living room to the garden or simply let more light into the back of your house, new patio doors make a real difference to how your home feels day to day.
What patio door styles do you offer?
There are three main styles available, and each one suits a different kind of home and garden setup. Sliding patio doors are a great fit where space is tight. They glide smoothly on a bottom track and take up no room when open, yet the large glass panels bring in a lot of natural light. You can choose from two, three or four panel configurations depending on the width of your opening.
French doors are hinged and open outward as a pair, giving you a wide, clear opening with a classic look that suits both older properties and newer builds. Bi-fold doors are the other option, folding back in sections to open up almost the full width of the wall. These work particularly well on larger rear extensions or kitchen dining rooms where you want the garden to feel like part of the space.
What materials and colours are available?
Frames come in uPVC or aluminium. uPVC is a solid choice if you want good thermal performance and low ongoing costs. Aluminium has slimmer sightlines, which means more glass and a cleaner, more contemporary look. Both materials are durable and need very little upkeep.
On colours, you have a good range to choose from. Popular finishes include:
- White, the classic option that works with almost any property
- Anthracite grey, a popular modern choice that suits both uPVC and aluminium frames
- Black, particularly striking on aluminium bi-folds or French doors
- Woodgrain effects, which give a warmer finish without the maintenance of real timber
- Dual colour options, so the inside and outside of the frame can be different shades if needed
How energy efficient are your patio doors?
Every patio door we install comes with A-rated double glazed sealed units as standard. The units are filled with argon gas and fitted with warm edge spacer bars around the perimeter, both of which help reduce heat loss through the glass. That means less cold air coming in from the garden side during winter and less reliance on heating near the back of your home.
The frames themselves are also thermally broken, meaning there is no direct path for cold to travel through the profile from outside to inside. This matters more than most people realise, particularly in older homes where a poorly insulated door can make a room feel noticeably colder.
Are your patio doors secure?
Security is built into the doors rather than being an optional extra. Every door we fit comes with a multi-point locking system that engages at several points along the frame when you lock up, not just at a single point like a standard door lock. Anti-lift devices are included on sliding doors to prevent the panels being lifted out of the track from the outside.
The glass itself is toughened safety glass throughout. On bi-fold and French door options, you also get shootbolt locking at the top and bottom of the active panel, adding another layer of resistance at the points where forced entry is most commonly attempted.
How long does fitting take?
For most patio door installations, fitting takes a single day. The team will arrive in the morning, remove your existing door or opening, and have the new door fitted and sealed before they leave. There is a small amount of making good around the frame once the job is done, and we tidy up fully before we go.
Bi-fold doors on larger openings can sometimes take a little longer depending on the number of panels and the condition of the existing structure. We will always give you a clear idea of timescales before any work starts so you know what to expect.
What guarantee do I get?
All patio door installations carried out by Newton Mearns Windows And Doors come with a full 10 year guarantee. That covers the frames, the glazed units, the hardware and the fitting. If anything develops a fault within that period, we will sort it out.
Right now there is a sale running, and Newton Mearns homeowners can save up to 50% on the cost of new patio doors.
