SOUNDPROOFING - IS THIS A FAIR QUOTE?

    Im looking to get some guidance on how fair this quote is, would one consider it reasonable?

    My house needs to be sound proofed. This requires party wall being striped bare - removing existing plaster board, sand cement etc.. down to the original cavity wall and being rebuilt again. This would involve batons being placed on each party wall, followed by layers of rockwool in between, new plaster board, re-skimmed etc. The job will take a week to do and the quote Ive been given is approx E8200.
    This quote consists of: materials & delivery approx E3k, labour E3k (which consists of carpenter x2, plumber, plasterer - (how much they are required during the wk, i dont know? as i would think the major job is plasterwork)), VAT approx E1k, 10% profit for the company all going well and revenue commitments, company insurance etc. I still have to allow for an electrician. The house is left in the same condition as it was found only it is not re-painted - we have to do this ourselves.

    I trust the company going by what ive been told and there have been no complaints (as far as i have been told!) however, I just want to be sure that we are not being ripped off as Im sure you can appreciate, it is not a cheap job to do. Any comments would be appreciated! :)

    Are you 100% that the solution offered will actually work? In my opinion adding density to the build up will be of benefit - not putting insulation between battens!

    PM me and I'll put you in touch with someone who can advise.

    Dont know if Im a bit late responding to this.
    Im going to get a wall done in my home by a company I saw mentioned on these boards and on pick a pro.
    I figured if I was going to get the job done Id get it done by someone qualified in sound reduction rather than just building qualifications or experience.
    It seems to be a very complicated area, from what I have read on these boards and on others, which if not done right can be a waste of money. Also theres a lot of different people selling different methods of sound proofing with different products.
    Anyway I dont know yet if I made the right choice but thats how my thinking is going.
    So regarding your question. I went to Acoustifire and got a quote for about 1400 and its going to cost a bit extra because I may need a wardrobe moved and sockets refitted.
    Also and I think this is important the guy reccomended doing only one room at a time, to see how well it fixes the problem.

    It is possible to significantly decrease sound attenuation in walls. I've designed and built a hearing aid clinic, recording studio and hotel bedrooms.
    I do not understand why the OP's builder is removing plaster down to the bare block. Unless he plans to check mortar has filled all blockwork.

    I would dry line one wall with accoustic material (many available) or soundblock gypsum plasterboard on battens with rockwool between. Rockwool also needed in roof space if it's a 1st floor bedroom and maybe even in timber floor. 'Flanking' is a big problem with sound proofing. That is where you have made a wall soundproof but the sound goes over, under or around the wall. See how one room works and then do another.
