These doors make a statement and give a fantastic first impression for those that come knocking.

High security as standard

Our doors are designed with security in mind. There are multi-point locking mechanisms tested to the very highest British Safety Standards. To further increase the security they also have two sets of triple dog bolts to keep intruders out and your family safe.

We would like to put on record our complete satisfaction with the conservatory that your company planned and built for us. We were very impressed with the speed and tidiness of your workforce – not once did we have cause complaint in the way they left our property neat and tidy after each day’s work.
Our special thanks go to Darren, Nigel, Ken, Lyndon and Dave for the way in which they conducted themselves. They were all very pleasant and courteous and put themselves out to ensure we were not inconvenienced in any way.
Their standard of work was exemplary. Thanks too, to you Tony for your advice and guidance in choosing the conservatory and for ensuring that everything went to plan and with the minimum of fuss. We will certainly recommend your company to our friends and neighbours and, if at any time you would like to bring prospective clients to view the ‘finished product’ please feel free to ring us. It will be a real pleasure”.
Kindest Regards
