A good door is only as good as it’s fitted. Precise fitting of all doors is essential to maintain ease of opening and closing and reliability over the years to come. Unfortunately, too many get fitted or setup incorrectly. Here at Verysecuredoors, every installation completed by us is carried out to the highest standards leaving no margin for error and we back every single door to operate smoothly and keep draughts out because we know the small details matter when installing and setting up a door and that’s what makes us stand our from the rest.

Professional Composite Door Installers

With over 1,000 doors supplied and fitted by us, we have the experience to ensure all composite doors are professionally installed.

We have fitted composite doors for people who are very well known and don’t want anything other than a good composite door supplied and fitted backed by a first class service but complete anonymity. We take many photos of our door installations but sometimes the customer requests that no mentions or any photos on social media whatsoever so we completely respect those wishes.

Jim and Josh can’t stress enough about getting a reputable installer for your new composite doors as we get at least two calls a month from people who have had doors installed where things haven’t gone too well and that the company that had fitted their door had done a bad job and have now have disappeared on them leaving the customer with a good door butfitted badly. A good composite door badly fitted actually becomes a bad door. Sometimes we can help out where possible but often the workload prevents being able to and it’s not nice to see someone who has paid out a lot of money for composite doors only to be let down by an installer who didn’t know what they were doing.

What are Composite Doors?
What are composite doors? Roughly speaking, composite doors are made from modern materials that mimic the appearance of a natural wooden door without some of the negatives that a wooden door can bring like having to paint it for example.

There are many makes, manufactures and styles of composite doors on the market ranging from average quality to very good quality. Some composite doors are mass produced in three different sizes in China and shipped over to the UK in containers ready to be machined to the right size, have the glazing fitted already and possibly sprayed to the desired colour. A frame is made for the door, a locking system along with hinges and hfurniture is attached and there you have a generic composite door.

The door can only be as good as the quality of materials used and the workmanship bringing it all together. Generally these are the lower cost composite doors that we tend to stay away from because we would rather fit a better standard of composite doors. After all they are built to a budget. The cheaper composite doors however make doors much more affordable (i.e what you would find on a typical new build house) but you get what you pay for.

One thing we don’t like about these door slabs shipped over in mass quantities is that because they use three different sizes you could find that the one used for your composite door has had a fair amount of material removed form the sides to get the width you require, thus weakening it in the process and making it easier to fail if someone tries to break in. The core for these composite doors is generally polystyrene or low density foam which sounds a bit lightweight but actually it is not as bad as it sounds but still not great from a security, robust and efficiency point of view.
Timber Composite Doors

Timber composite doors are the way the likes of Rocal Endurance, Solidor and Solid core doors manufacturer doors. These are made from timber which are cut to size so there is no weakening of the edges of the slab as the strength is consistent across the entire width and height of the door.

Timber composite doors are generally more expensive than generic foam / polystyrene composite doors. One reason for this as well as timber is more expensive in general is that timber is heavier than foam and polystrene so these types of composite doors are heavier meaning hinges and external frames need to be more robust and stronger to be reliable over a long period of time to prevent the door moving and to properly take the weight of the door.

Another reason they are more expensive is because they are considered a higher end composite door compared to the more light weight foam and polystyrene doors as they typically always have better locking mechanisms and cylinders. All the composite doors mentioned so far use what is called a glazing cassette so the glass unit can be added towards the end of the build process and can even be changed at any point in timeif one were to be broken by say a stone. In 15 years of dealing with doors we don’t come across many broken glass units in doors to be honest.

Foam Filled Composite Doors
Another composite door called the Rockdoor is built completely different from the timber composite doors. They use a foam filled door with a 10mm aluminium box section in the door slab for proper reinforcin and is made based upon the size required so you get the same strength around the edge of the slab on every door they make. Even though they are foam filled and having fitted over a thousand of these doors we have never come across one that has been broken into due to having a foam centre. Many timber composite door manufacturers like to make a point of the core of their doors being made from wood thus being harder to penetrate than a foam filled door but in the real world this isn’t really an issue. Where a Rockdoor is unique is in the fact that each glazing unit is built into the door as it is made and is integral to the door. The downside would be if the glass were to break but I have only come across one instance of this but it was shot at with a pellet rifle. A broken glass unit would mean a new slab would be required but it’s a non issue really.
How to fit a Composite Door?

Perfectly is the correct answer. Here are a few very important steps to ensure your new composite door is properly installed: (not in an installation order) 

1) If your new composite door is sitting on a cill, ensure it is completely level, packed underneath so it doesn't flex when the weight of the door is put onto it and ensure it is sealed properly. If its not sitting on a cill, ensure the base layer (generally Stone) is level and flat.

2) Check that the door header across the top of the door is parallel. If the gap gets bigger towards the lock side, it either wants packing across at the top towards the hinge side, or packing across towards the latch side at the bottom, depending on how it looks on the inside/outside. If the header is parallel but you have a swing on your door at around 90 degrees opening, the base/cill is not level. You will have to raise the cill on one side and then recorrect the positioning of the door.

3) It is important once the composite door is in to check the swing of the door, opening the door to 90 degrees tests the side to side level (please use a level to ensure complete accuracy), if it swings one way or another, the door is not sitting square, opening the door to around 30 degrees will test the front to back level (please use a level to ensure complete accuracy), generally most plaster is out of level so you never push a door back to the plaster, it can only take a couple of mm to put a swing on a door. If it swings at around 30 degrees, then it wants the top or the bottom bringing forward or backwards depending on the situation. 

4) Check the twist. The twist on a composite door is an extremely important part of door installation. The twist refers to how twisted the frame is to the door, you want the front edge of the door to be touching or passing the frame top to bottom at the same time, we often see doors that are shut on the latch and its touching the seal at the top of the door, but the bottom of the door is 6-10mm away from the seal, this is almost always because of the twist. To correct the twist, ensure the hinge side is level front to back and then move either the top or bottom of the lock side inwards or outwards to correct.

5) Ensure all fixings are packed and the remaining gaps are filled with expanding foam. Check with your level that the hinge and lock side of the frame are not bowed in any direction and are completely flat.

Help Choosing the Best Composite Door?

All of the composite doors we fit are good quality and generally a customer will make their choice primarily based on the look of the door and the colour rather than the different features. If you need help or are undecided with choosing which composite door for the front, back or side of your house, contact us. A few observations below however:

1) Rockdoor are the most secure composite door we offer and also feel the most premium, especially when combined with Steel Mesh and 4 Hooks (neither of these are essential in my opinion having experienced a Rockdoor attacked with a sledgehammer and 2 hooks, coming out virtually untouched).

2) Solidor offer the greatest amount of accessories, furniture and customisation etc on a composite door.

3) Endurance composite doors by Rocal offer the widest variety of different door designs, colours and glass styles.

4) Solid core doors by future products are fantastic value for money for people who are not too fussed on design, colours etc. They provide great security for the price.
