First impressions count! The front door to your home is your welcoming card and the only chance to make that all-important first impression.

Here, at J’aDoor we understand that your entrance needs to be both aesthetically stunning whilst offering the highest possible protection to your home and family – both requirements come as standard with our High Security Doors.

Our Security Doors and frames are steel cored structures clad in of a variety of external sheet materials offering complete weather proofing with minimal upkeep over the years. Sold complete with high specification locks with a multitude of locking options to suit your everyday needs, and your choice of door furniture from a vast selection of finishes and styles.

The High Security doors from J’a Door are available to several different levels of security, all of which are far beyond that of standard insurance requirements. Extensive research has been carried out to prevent all possible ways of forced entry resulting in the Level 3 door and constantly updated testing keeps the security level to one that we are proud to install.

Level 3 door advantages include as standard:

  • 100mm L-shaped profile, fixed into the aperture with 16 pins, including steel liners of 24mm
  • 75mm (total thickness) steel core door leaf
  • Hinges with supported bearings
  • Locks, including at least one with a drill resistant plate, which bolt three edges – side, top and bottom
  • Hinge bolts onto the hinge side supplied as standard
  • Insulation seals all round
  • Thermal insulation in both door and frame

We can also offer you higher security – adding additional locks if required, or supplying the Level 4 security rated doors which raise the protection to a bulletproof model. Additional qualities for this level include:

  • Armoured locks, protected by two drill-resistant plates
  • Both locks being installed into steel boxes
  • Additional security hinges
  • Minimum of 8 hinge locking bolts
  • Additional bolts to locks on three sides, a total of 10 bolts all protected within a steel sleeve
  • Double insulation – for both thermal ratings and noise reduction

As you can tell we offer a wide range of reliable high security doors. They will satisfy the most demanding customers by combining high quality and high security with affordable prices whilst offering unlimited styles and design features. We have installed both modern and traditional styled doors from high gloss finish to satin in any colour you desire, as well as a huge selection of wood-type finishes from oak to wenge (all without the upkeep required by standard wooden doors). You are in control of the design, the colour, the finish (both inside and out) and the overall look – or of course, we can help you and suggest alternatives suit the style of your house, apartment or business.

As far as the design is concerned, we can make the doors to suit your opening – incorporating top and/or sidelights to allow light in but not compromising on security – in fact, if you prefer to have glass within the door structure we can arrange for this as well. The unlimited designs available for these doors need not be the same externally as on the internal side of the door – why not match the internal side to your existing doors inside the home?

Finally, the furniture for the door which can really make your door stand out from the rest, available in both contemporary and traditional styles, in a multitude of finishes – there are numerous designs to select from. The extensive choice can really make your door your own.

With each security door, we offer a fitting service, which includes an on-site survey prior to production, to ensure that measurements are correct and any restrictions that may apply are dealt with before the door set is made. An approval drawing is created for each order so that each customer is fully aware of the look of the final door. Fitting dates can be arranged for your convenience and we are more than happy to work with any other trades on site to ensure that your project runs smoothly. For your further security, each door is supplied with installation key, to be replaced (and disabled) by final keys at the end of the installation work.

We aim to provide you with a stress-free service, from design through to installation to enable your vision to be brought to reality.

High Security Doors

Step 1

On meeting with the client and establishing the requirements for your new security door, we create an estimate to include the supply, finishing and fitting (where required) for the structure. We do try and take as many details as possible at this stage so that this initial quote is accurate, and in most cases, will not alter throughout the process.

Step 2

Once you are happy with the quote we will take a deposit for the order and (and assuming we are to fit the new door) arrange for a site survey to be carried out to establish accurate measurements and any special requirements to ensure a smooth fitting. We are happy to work alongside your contractors if openings are to be made, but insist on a site survey to eradicate any future issues that may arise if this is not carried out.

Step 3

An approval drawing is created to ensure that positioning of door furniture and opening direction is correct – and we are all happy with the look of the door.

Step 4

Once approved, production is confirmed and a fitting date is arranged.
