Background: Clients were experiencing airborne and impact noise from flat above and loud ‘cracking’ noises from the lathe and plaster ceiling. They had employed someone to overboard the ceiling with a layer of plasterboard but with little improvement. The owner of the flat above was not prepared to consider any treatment to the floor so all work needed to be done from below.
We were concerned about adding extra weight to the floor/ceiling structure in view of the ‘cracking noises’ so removed two small areas of ceiling to expose the ceiling void to check the depth of joists. Having discussed with our structural engineer, we decided to propose a solution which involved the complete removal of the existing lathe and plaster ceiling and over boarding. Following removal of the waste, gaps in the floorboards above were sealed from below and a new suspended acoustic ceiling was fitted and a plaster skim applied.
We guaranteed that the new ceiling would meet the impact and airborne sound requirements for conversions carried out under building regulations part E. However, the clients were so pleased with the final result that they decided they didn’t need a final sound test.
The clients wrote: “Dear Mr Harris
I’m writing to thank you and your company for the recent work you carried out, providing my wife and myself with a a sound-proof ceiling in our living room. Your team worked incredibly hard to get the job done within the planned schedule and showed flexibility in dealing with unforeseen issues when they arose (without adding excessive costs to the project). We have now been able to enjoy our living room fully for the first time in years, without being disturbed by noise from above.
I wish you continued success with your company and would certainly use your services again should similar work be required.
