Hi All. Can someone please help me? I am a Carpenter/ builder and just finish a job which is listed below. the home owner has asked me for a certificate so that I can get paid? I made it very clear before I started the job that I could not supply a certificate but only those issued by the manufactures? How do I go about this? Here is the list and details of what I did. 1.. took out existing glass in transom and replace with 7.2 Pyrogaurd. fitted them with hardwood beading, glued, screwed, and 30min fire seal tape both sides. All glass are etched I basically followed instruction I found online. 2.. Removed existing 100mm steel hinges and replaced with fire rated hinges with a third added to the centre, so now all doors have 3 x fire rated hinges. 3..Replaced a badly fitted door, like for like FD30 with intumescent strips, sides/top 4.. 2 x doors were cut too short by previous owner, they had wood flooring. so the gap at the bottom were 30mm. so I added a hardwood threshold to get the gap to 5mm. Thanks in advance, your help is very much appreciated. Cass
