Installation of your bifold doors when installed by us we will always use professional fitters, and at least one of our team members will be a carpenter. Our installation teams have at least two members but sometimes three. Each team know exactly what is expected of them, they install the doors to a high standard and always leave the property clean and tidy.
Supply only bifold doors
Many of our clients choose to save the installation cost and install the bifolding doors themselves this can be carried out by any competent DIY person or builder. Full installation instructions are provided with every supply only order.
Bifolding doors are factory assembled
Every door is fully assembled and set up in one of our auto square assembly jigs. These jigs ensure the doors are fully operational before they are passed to despatch. The doors are completed in an upright position and every door checked to make sure it works correctly.
Quality control of bifold doors
When production has been completed before the bifold is removed from the jig a quality control inspection is carried out by a different employee who checks for ten operational functions and fifteen quality items. Once passed the order is checked to see how the client or surveyor wants the door is delivered. Around seventy per cent of our bifolding doors is delivered complete ready for installation. The balance of thirty per cent have the doors removed and the frame was taken apart. The reason for flat packing the frame is generally because of limited access to the premises or risk of damage because the doors are simply too big to manhandle. When released from the quality control they are wrapped under the supervision of the quality inspector ensuring their preparation for transit. Quality control staff remain in control of the doors in the storage area until they are loaded on the vehicle ready to leave our factory. This ensures all parts are loaded together and none of the product is damaged. The process reduces the risk of incomplete deliveries or damaged goods. Quality control staff don’t load the vehicle they merely supervise the correct handling, loading and securing the load ready for delivery.
Bifolding door installation day
Our installation team will arrive at the same time as the delivery driver. The goods are unloaded and made ready for installation. The very first thing done by the fitter is to inspect the opening and check the dimensions to ensure a successful installation. The fitter will level the base brickwork setting the height to ensure the finished floor height is correct. These doors have to be installed level. When the base is level the cill if required is laid and the frame is set onto the brickwork. The frame is then fixed level and square using the correct length direct fixings. After the doors are set-up and glazed the doors will be operated a few times, then when the fitter is happy with the set-up he will use fixing foam to fill any spaces he feels necessary. This fixing foam is never used to fix the frame only to fill any larger gaps. The doors are always fixed using direct fixings and metal fixing screws into the head of the lintel. We use fixing foam because it does not expand too much and is more controllable it also cures a little quicker. You must make sure no foam contacts any visible part of a door as it will mark the finished product. The door is then sealed around the perimeter. The fitters will then remove the protective tape. You will need to inspect the door prior to them leaving a site as any damage to the doors post-installation will not be accepted as our liability.
