Welling leasehold flooring — impact-sound compliant underlay
Complaints from the flat below almost always trace to two things: no acoustic underlay, or an underlay bridging the wall via the skirting. Around East Wickham 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.
What acoustic underlay for flat conversions in Welling actually involves
Complaints from the flat below almost always trace to two things: no acoustic underlay, or an underlay bridging the wall via the skirting. Around East Wickham we've retrofitted hundreds of flats where the original fit passed sound testing then failed a year later because the perimeter wasn't isolated.

Falconwood bungalows often sit on solid concrete — minimal prep, ideal for LVT.
Three things that decide a lvt fit in Welling
- Subfloor flatness
LVT shows every bump — 1930s semis subfloors in Welling almost always need ply or self-levelling screed first.
- Door undercut
We trim doors on the day so they swing cleanly over glue-down LVT — no scraping, no callbacks.
- Pattern direction
Plank run follows the longest sightline; in narrow Welling hallways that means front-door to kitchen.
- Rubber-crumb and cork-composite underlays rated ΔLw 18–21dB
- Meets typical London leasehold requirement (≥17dB impact reduction)
- Signed spec sheet supplied for managing agent / freeholder approval
- Perimeter isolation strip fitted so plank noise doesn't bridge the wall
Bottom line: if your lease says 17dB, standard foam won't pass. We fit and document the underlay that will in Welling.

Acoustic Underlay for Flat Conversions in Welling — 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 Welling 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 Welling 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.
