Fit lease-safe flooring in your Orpington flat
Complaints from the flat below almost always trace to two things: no acoustic underlay, or an underlay bridging the wall via the skirting. Around Petts Wood we've retrofitted hundreds of flats where the original fit passed sound testing then failed a year later because the perimeter wasn't isolated. We fix both — underlay spec and perimeter isolation strip.

Acoustic Underlay for Flat Conversions in Orpington — common questions
We provide the underlay's independent test certificate (BS EN ISO 717-2) plus a photo record of the perimeter strip and floor build-up. That's enough for 95% of Orpington managing agents; full on-site sound testing is a separate acoustic-consultant job.
A 5–10mm foam strip around the wall edge stops the plank layer touching the wall or skirting. Without it, footfall bridges into the party wall and the downstairs flat still hears it — even with a great underlay. We fit it as standard.
Only by lifting the LVT first. If the LVT is glue-down we usually replace it; if it's click-lock we can lift, add underlay and refit — subject to a condition check on site.
Usually yes on Orpington leasehold flats. We supply the underlay spec sheet and product data ahead of the fit so you can get written approval — most agents turn it round in a week.
