uPVC doors can come in all shapes and sizes and be made for both front and back. The benefits on a uPVC door is that they require very little in the way of maintenance as oppose to an external wooden front or back door. A wooden external door will require painting and some form of weather protection applied every couple of years. uPVC doors can be installed and then wiped clean once every so often and they'll keep looking as good as new for years to come.
You can find uPVC doors fairly cheap now. Due to the popularity of them a standard size front or back door should be around £150-£200. They come complete with the frame, hinges, locks and door knocker too. So when comparing prices to a wooden front or back door this is worth remembering.
Cheap uPVC french doors, or patio doors as they can be called can be pretty easy to come across too. Again, these come in complete sets including the frame, locks and so on. For a full set you should be looking around £500. But take in to account that you'll need the a space bigger than a normal size door, and fitting them isn't as easy as a uPVC front door.
If you're looking for something a little fancier, like bi-folding doors then expect to have to pay a fair amount more. Finding low priced bi-folding external doors can be hard. B&Q have some good bi-folding doors to look at, but the cheapest ones start at over £1000. They do look great, but be ready to pay out for them. It pays to spend time looking at the clearance section of websites, and even making a trip to your local B&Q or Wickes to see if they have any older styles that are reduced.
B&Q and Wickes are great for getting the best deals and offers on uPVC doors of all types as they often need to make space for more stock, and most of us are usually never that far from one, or both of these DIY stores. We've got listed here the cheapest external doors from both of these retailers. This makes it easier to find the best deals. We have also made sure we include any sales that they have on uPVC doors too.
