- Well everything's been 'bricked up' in his words and is cemented(?) in. He's back tomorrow to skim it.
- Yes he's suggested that someone has tried to effect a repair previously. He's also doing work on the exterior, so my hope is that what's going on outside will solve it. They are offering a 20 year warranty (whatever that's actually worth...)
- Yes the existing air brick is unobstructed and he's putting an additional one in at our request for good measure.
The wood floor is a concern. We actually had the same issue this time last year when a builder allowed debris to get underneath the corex and scratch/dent the floor quite heavily at the other end of the room. Frustrating to say the least.
Thanks for your pointers!
