Tony I was just having a laugh mate, yes you are right if it is a fire door then it is best to leave it to the professionals, particularly in HMOs.
As for solid core blank, as I am not into wood or joinery works, I might know more about boilers! (ha Ha) is this a solid door we call? Do
Wickes not stock various types?
Oh talking of how much to cut off the edges of a door, I will tell you a story and you will die laughing!
we saw an ad and
Wickes had a special offer on internal doors, they were flogging internal doors for £9.99!
me and my mate were renovating a house where we decided rather than to repair a smashed door that we might as well buy this cheap door and cut and fit that,
So we took measurements and the width was 28" and length about 78" and it was for a small utility room.
we hopped over to
Wickes, and found that the only door they had on low offer was surplus stock in size 32" width . all others were normal price, so we asked the store to trim 2" of each side, but the guy who runs the cutting workshop or counter refused to cut it and said they had a policy of not trimming any doors, unless I first pay for the door and obtain approval from his manager.
So we did, paid for it and got the store manager's approval, at our risk, and no come back, so we both had a feeling that if we trim 2" we might not be so lucky and we could start seeing the inner honeycomb spacer they use.
so as soon as the guy started to cut we could see the honey comb was showing through the cut, but the guy continued cutting as if it was OK, he did not stop,
so he then turned the door over and cut off 2" from the other side as well, as if it was OK.
Both me and my mate never felt so embarrassed and felt like a couple of prats,
As soon as we got out of the store we couldn't stop laughing at our selves, and we hurried to our van to hide it quickly, before other customers see us, at one point we were almost going to leave that door in the car park but then if we did, we would not have been able to return to that store ever again to show our faces!
Still we spent the next two days to glue and fit in the edging that was taken out and we managed to rebuild that door and fit it in, in the end it cost us probably £200 in our labour time!
it pays to call de professionals!!
