Hi again
Dermot did indeed come back with a reasonable price, a wee bit more than we had hoped for - but not as bad as we feared ...
Indeed we went to visit one of his reference sites, and they were full of praise for him. We actually changed our design considerably based on what he done for this family, and he came up with other ideas some of which were very useful and we're more than happy with the design now. The price has gone up from the original one, but the design bears no resemblance to the original so he's fine there.
He says he only deals with one property at a time, and so was able to start work within one week of when we originally talked to him. The only other contender who we were talking to was saying 6 to 8 weeks before he could start ;-(
So we've gone with Dermot - he's on site (I hope) as I write. He's done a couple of days work, we had 4 men on site at 8am on Saturday morning.
So far so good ...
