What Are The Main Problems With Composite Doors?

problems with composite doors

It’s not so very long ago that the UK went a bit mad for those delightful white uPVC doors. That was around the same time that shoulder pads and mullets seemed like a good idea too!

Thankfully, for most of us anyway, times have moved on, and along with mullets and shoulder pads, bog-standard white uPVC doors are no longer our first choice!

Today, composite doors (and hipsters, sadly) are all the rage. In this case of doors, the composite variety are likely to be here to stay. So what exactly are they, what are their benefits and are there any problems with composite doors? On this page we’ll take a look at those questions in greater detail…

Composite Doors: The Basics

Composite should give you a good starting point when it comes to the ‘what’ question. Different to uPVC doors (made purely of plastic) composite doors are made with a variety of different materials.

This is designed to make them sturdy, long-lasting, secure and more attractive than a plain old plastic door.

Composite Doors: The Manufacturing Process

As mentioned before, composite doors are created using a range of materials. These are glued and pressed together under high pressure.

This includes: timber from sustainable sources, glass-reinforced plastic, and sometimes metal too.

The process creates a much stronger, thicker door, which offers better security and better insulating properties than old-school uPVC.

In addition to this, a composite door will also have a PVC subframe and hardwood inner frame, which supports the overall structure, making it resilient to all types of weather, and far stronger and more secure.

Unlike UPVC doors, their composite cousins contain a layer of polyurethane foam inside, enhancing their thermal efficiency; a must if you live in more Northerly parts of the country, where harsh Winters are the rule rather than the exception.

Problems with Composite Doors

There aren’t many problems with composite doors, but if you’re a D.I.Y enthusiast, they may not be the easiest to deal with. They’re extremely weighty – thanks to their solid construction.

If you want to fit them yourself, it’ll be at least a two-person job. Generally speaking, it’s advisable to have the door fitted by a professional firm for the best results.

One other minor drawback of this door type is that they are slightly more expensive than UPVC equivalents; mainly due to the fact that they are made from several different materials, and consequently, take longer to manufacture.

However, cheaper choices often, in the long-term, prove to be a false economy. If you receive a quote for your new front door that seems to good to be true then it probably is-and is unlikely to last as long as a door made from quality materials.

Some homeowners also comment on how their composite doors take a lot of effort and upkeep to maintain. While to a certain extent this is true, they are definitely far easier to preserve than tradtional wood-which is prone to rotting and warping.

Sometimes, Choice Can Be a Bad Thing!

Choice, colour and style is all very well, but once you’ve made the choice, you will have to stick with it. If you change the colour scheme of your home, it’ll be hard to change the colour of the door!

The same applies to plain old uPVC of course, which will stay decidedly unattractive, whatever you do to your home.

Highly engineered and designed, composite doors and frames really need some expertise when it comes to fitting. Some consumers have fallen foul when ordering “cheap” doors from inexperienced fitters.

Cracking in the unit, bowing or draughty frames can all be the result. Don’t choose cheap over experienced when sourcing a composite door installer/supplier.

Whatever the reason, replacing glazed sections is a simple and easy job.


Given their solid, hard-wearing construction it should be no surprise that composite doors offer a long-lasting solution.

Many have lengthy guarantees with companies suggesting that the average lifetime of a composite door can be 35 years.
