I hired William Hartley to soundproof my bedroom wall.
Unfortunately after the work was completed, sound came through just as before, so I contacted them to try and see if they would do some further work and finish the work they started. I had paid them cash in hand at a premium price compared to other quotes expecting a premium wall, so I would rather not have further work, but was willing to have it finished.
I was roundly ignored and dismissed. I was told theres nothing more they could do, and despite 7 emails, 2 voicemails, texts whatsapps etc etc, I am now £1000 down on a wall which has not done the job intended. I had 1 reply to these 7 emails, and it was stating they didnt know what else to do. That was it.
I have now hired another company who not only offered me a better quote on top of plastering, but have also pointed out thing that William Hartley have done wrong which could make the soundproofing worse than before, such as wood frames touching the sound source, and soundproof boards also touching the source.
In general, good workmanship, but if you have any problems, don't expect any help.
This would have been a positive review, and more money would have been in their pocket to do a second round of work, had they responded to my emails and accepted further work, rather than ignoring me and dismissing my questions. Its a shame they missed out on a great review and more money due to bad customer after-care. Wont be using again or recommending.
