London Case Studies: Measured Noise Reduction, Borough by Borough
Every project below includes real before/after dB measurements taken with calibrated sound level meters. No estimates, no marketing claims — just independently verifiable acoustic data from installations across London.
"We couldn't hold a conversation in the front room. Now it's quieter than our country cottage."
— James & Catherine R.
"The 5am freight trains used to shake us awake. Now we sleep through every single one."
— Tom & Lisa P.

About Our Measurements
Are these real measured results?
Yes. All dB measurements were taken using calibrated sound level meters during our standard pre- and post-installation acoustic surveys. Before measurements are taken with windows closed before installation, and after measurements are taken 48 hours after installation completion.
Will I get the same results in my property?
Results depend on your specific noise source, window configuration, and available reveal depth. Most London properties achieve 42-54dB reduction. We provide predicted performance figures in our free survey report before you commit.
How long do these installations take?
Most residential properties (6-10 windows) are completed in a single day. There's no structural work, scaffolding, or mess. You can continue living normally during installation.
