Front & Back Doors
Improve the appearance of your property.
uPVC doors are a popular choice for homes across the UK, and it’s easy to see why. They offer many benefits, making them a great choice for both a uPVC front door and a uPVC back door.
uPVC doors help to maintain high levels of energy efficiency with very little maintenance. No rot. No warping. No fading or discolouration.


The Benefits
Heading
The main benefit of a uPVC door’s low maintenance is the minimal upkeep required, as they do not need painting, varnishing, or regular treatments to stay functional and look good. They are resistant to rotting, warping, and fading, and a simple wipe down with a damp cloth is typically sufficient to keep them clean. This saves homeowners time and money compared to other materials like traditional wood.
Energy Efficiency
Multi-chambered uPVC frames combined with A-rated double or triple-glazed units cut heat loss right back. A new uPVC door seals tight against draughts, so the heat you pay for stays in the house — most customers notice the difference on the very next energy bill.
Durability & Weather Resistance
uPVC is built for the British weather. It won’t rot, swell or warp in the damp, won’t corrode by the coast, and won’t crack or fade in the sun. The colour runs right through the foil finish, so it keeps looking smart for decades with no repainting.
Cost Effective
Security
Every uPVC door we fit comes with multi-point locking, anti-snap and anti-bump euro cylinders, internally beaded glass and reinforced hinges — built and tested to PAS 24 against the methods burglars actually use.
Variety
Choose from 18 foil finishes including anthracite grey, chartwell green, irish oak and rosewood, dozens of decorative and obscure glass designs, and a full range of handles, knockers and letterplates — with different colours inside and out if you like.
Security
Multi-point locking and toughened glass come as standard, giving you the reassurance of a home that is properly locked up without having to think twice about it.
Quick Installation
Most jobs are in and finished within a day or two, with the mess kept down and everything tidied up before we leave.
Fix Don't Replace (3)
Most faults come down to a worn part or a simple adjustment, so a repair is usually far cheaper and quicker than a whole new window or door.
Genuine Parts (4)
We supply genuine parts for the common window and door systems, so the repair lasts properly rather than failing again a few months down the line.
Workmanship Guaranteed (5)
The parts we fit and the work we do are guaranteed, so if anything is not right after we have been out, we will come back and put it straight.
Our Suppliers
We work with a range of local suppliers to ensure you are looked after every step of the way.
What is an anti-snap cylinder and do I need one?
It is a cylinder built to resist a break-in method where the barrel is snapped. If your door has an older standard cylinder, upgrading is a cheap and very worthwhile security improvement.
I have moved house, should I change the cylinders?
It is well worth it. You have no way of knowing who else holds a key, so fitting new cylinders means only your keys work. It is quick and inexpensive.
Can all my doors be on the same key?
Yes. We can key your cylinders alike so one key works every door. Just let us know when you book.
I have lost a key, is that a problem?
Will a new cylinder fit my existing door?
In nearly all cases, yes. Cylinders come in standard sizes and we measure to match, so there is no need to change the whole lock or door.
Is it guaranteed?
Yes, the part and the fitting are guaranteed.
