Yup, they should. This is still ongoing but seems to now be quite close to being sorted.
Not bad eh? Only took them 2 years to admit there was a fault and to fix it.
That's great that you go it fixed. I logged this as a seperate thread not thinking it would be a common problem.
I'm having a problem too - I'm unsure to contact the builders and get them to do a sound test as it has been a year and a half since I moved in - or have my own done and contact building control i.e. local authority?
I've heard from a diff builder that there's very little that can be done when after construction. I've even heard of someone having the builder come and do remedial work. The person moved out of the house for the duration of the work and when they came back it wasn't much better. That's why I've been reluctant. But as I listen to the family next door have dinner and my neighbour listening to techno music I think I'm going to have to do something.
