Really pleased with the sound proofing work Nigel has done. I was experiencing daily noise from the tumble dryers and vibrations & noise from the washing machines in the Communal Laundry serving 40 flats . The laundry is situated below my flat . Following the work Nigel has done for me, I can no longer hear the tumble dryers. The noise & vibrations from the washing machines has decreased by at least 80%, which is great and more than I expected due to the nature of how some other residents use the laundry.
