If you want your home secure then an endeavour door fitted by Tri Tec is the way to go, the quality and build of the door is superb, locks are some of the best and fitted perfectly. It may cost you a bit more, but how much do you value your security, I would never use a high street window company again. Just you tube or google Endeavour doors, you will see the benefit of these doors and they are fitted by Tri Tec a local company.

Tri Tec were quick to respond to all communications and scheduled appointments were attended on time. The sales guidance and various door options were clearly explained to me. The installation team arrived on time, they were polite and tidied up any mess which they created during the replacement of our front door. The Endurance door product that we selected appears to be well made and I cant fault the overall service. I would recommend Tri Tec to anyone.
