Sliding uPVC Patio Doors for Light, Views and Easy Garden Access
uPVC is a popular choice for patio doors because it is affordable, low maintenance and clean looking, and it will not warp, swell or rot in the British weather. A sliding door glides along a track, so it suits narrow gardens, tight kitchens and any room where furniture sits close to the glass.
Our uPVC patio doors are made to measure in two, three and four pane layouts, with durable frames, strong locking and double or triple glazing. Our FENSA certified team fits them with a full product and installation guarantee, across Hayes, Hillingdon, Uxbridge, Southall and Yeading.
Light and views
- Large glass panels flood your kitchen, dining room or lounge with natural light
- Panels glide on a track, so no floor space is needed for a door to swing
- Two, three and four pane layouts suit narrow openings and wide extensions
- Colours and woodgrain finishes match your windows and your garden room
Security and everyday use
- Anti-lift blocks and hook locks stop the door being forced or lifted off its track

- Frames never rot, swell or need repainting, and the track wipes clean
- FENSA certified fitting and a full guarantee give lasting peace of mind

What Is Inside a Sliding Patio Door
A sliding door looks simple, but its performance depends on a handful of parts working together.
- Track: a low rail along the cill that the moving panel runs on
- Rollers: adjustable wheels under the moving panel that carry its weight
- Fixed panel: stays in place and is mechanically secured to the frame
- Locking: a handle that engages hooks into the frame, plus a lock cylinder
- Seals: brush and compression seals that keep out draughts and water
- Drainage: small channels and weep holes that let rainwater drain out of the track

How Much of the Opening Will You Get?
This is the question most sliding door pages avoid. In a standard sliding door, the moving panel slides behind or in front of a fixed one, so at least one panel width of the opening always stays blocked. A two pane door opens roughly half its width.
| Layout | What it suits | Typical width range |
|---|---|---|
| Two pane | Standard openings, the best value | About 1.8m to 2.9m |
| Three pane | Wider extensions and more glass | About 2.4m to 4.2m |
| Four pane | The widest openings | Wider still, made to measure |
If you want the whole width clear, a bi-fold door is a better fit, and if you want a traditional hinged opening, see our uPVC French doors. We will tell you honestly which suits your space.

Which Way Should It Slide?
- Decide whether the moving panel slides to the left or the right, looking from the garden
- Choose the side that keeps the handle close to where you walk through most often
- Think about where your furniture, a patio table or a dining table will sit when the door is open
- Tell us how you use the room at your survey, and we will recommend the layout

Sliding Door Security: A Buyer's Checklist
Older sliding doors were known to be easy to force or lift off the track. Modern doors fix this with specific features. This is what to look for.
| Feature | What it does |
|---|---|
| Anti-lift blocks | Stop the moving panel being lifted off its track from outside |
| Hook locks | Engage the frame at several points so the door cannot be slid open |
| Secured fixed panel | The fixed pane is mechanically fixed to the frame so it cannot be removed |
| Anti-snap lock cylinder | Protects the lock from being snapped |
| Toughened glass | Stronger than standard glass and safer if it breaks |
| Certification | Look for PAS 24 or Secured by Design on the exact door you are quoted |

Is It Time to Replace Your Patio Doors?
Patio doors wear out slowly, so people often put up with problems for years. If several of these sound familiar, it is time to talk.
- The door drags, needs two hands, or jumps off the track
- Draughts, rattles or rain are getting in around the doors
- The glass has misted up between the panes
- The track is corroded, or the lock no longer lines up
- An older aluminium frame feels cold and attracts condensation
A worn roller or a dirty track can often be repaired cheaply. Replacement makes sense when problems stack up, such as misting, a corroded frame, a failing lock and draughts together. We will tell you honestly which applies at your survey.

Keeping Your Patio Door Gliding
- Vacuum the track first, so grit is not dragged into the rollers
- Wipe the track and frame with warm soapy water, and avoid harsh chemicals
- Clear the drainage channels and weep holes so rainwater can escape
- Apply a little silicone based lubricant to the track and moving parts, not heavy grease
- Check that the door still closes squarely and locks smoothly, and ask for the rollers to be adjusted if it drags
Do this once or twice a year and your door will glide for many years.

Light, Heat and Privacy
- Solar control glass can reduce summer overheating on a south facing garden
- Triple glazing adds warmth and sound reduction on cold or noisy elevations
- A low threshold makes access step free for wheelchairs, pushchairs and older family members
- Blinds, curtains or privacy glass add comfort and privacy where you need them
- Colour matching with your windows keeps the house looking consistent

Frequently Asked Questions
Ask Us a QuestionHow much of a sliding patio door actually opens?
Roughly half. In a standard sliding door, the moving panel slides behind or in front of a fixed one, so at least one panel width of the opening always stays blocked. If you need the whole width clear, a bi-fold door is a better choice.
Can a sliding patio door be lifted off its track?
Not if it is fitted with anti-lift blocks. These sit in the track and stop the moving panel being lifted out when the door is locked. Older sliding doors without them were vulnerable, which is one reason many people replace them.
Why is my patio door hard to slide, and can it be fixed?
Most sticking comes from a dirty track or worn, unadjusted rollers. Vacuum and clean the track, check the drainage channels, and ask for the rollers to be adjusted. If the door still drags, the rollers or track may need replacing.
Should I repair or replace my patio doors?
Repair if the problem is one worn roller, a dirty track or a loose handle and the frame and glass are sound. Replace if you have several problems together, such as misted glass, a corroded frame, draughts and a failing lock, because repairs then cost more than the doors are worth.
Which way should my patio door slide?
Choose the direction that suits where you walk, where the handle sits and where furniture will go when the door is open. Left or right is chosen when the door is made, so it is worth deciding at your survey.
How wide can a sliding patio door be, and how many panes do I need?
Two pane doors suit standard openings up to roughly 2.9m wide, and three pane doors suit wider spans up to roughly 4.2m. Wider openings usually need four panes or more. Ours are made to measure, so we match the layout to your opening.
Can I have a low threshold for step free access?
Yes, a low threshold option makes access easier for wheelchairs, pushchairs and older family members. It can affect weatherproofing at the base of the door, so we talk through the trade offs and recommend the best option for your garden level.
Will a large glass door make my room too hot or too cold?
Not if the glass is chosen well. Solar control glass reduces summer overheating on a south facing garden, and double or triple glazing with strong seals keeps heat in during winter. Curtains or blinds add extra control.
How much do uPVC sliding patio doors cost, and are prices higher in London?
UK guides put a fitted standard two pane uPVC sliding door at roughly £1,200 to £2,500, with larger sets costing more. Guides also report that London prices typically run about 20 percent above the UK average because of higher labour costs. These are national figures, not a Eurothermal quote, so book a free survey for an exact price.
When are patio doors a better choice than French doors?
Patio doors suit wide openings, narrow gardens and rooms where furniture sits close to the glass, because they need no space to swing. French doors suit narrower openings, a traditional look and a lower budget. See our uPVC French doors page for the other option.
