Heritage looks,
modern performance
Authentic timber aesthetics in maintenance-free UPVC, plus premium aluminium windows and doors. Sash windows, casements and front doors installed across the South East — the heritage look, without the upkeep.
The Collection
The timber look,
without the timber
Our UPVC range is engineered to replicate authentic heritage timber — from woodgrain foils to traditional glazing bars — while our aluminium casements and doors deliver slim sightlines and contemporary precision. Both bring modern thermal performance and zero maintenance.

Why Fenestral
The difference
is in the detail
Precision Installation
Every installation is surveyed with laser accuracy. We measure twice, fit once — ensuring perfect alignment, seamless operation, and zero compromise on thermal performance.
Guaranteed Quality
All products carry manufacturer-backed warranties of up to 25 years. Our installations are FENSA-registered and insurance-backed for your complete peace of mind.
Bespoke Specification
No two homes are alike. We work from architectural drawings or on-site surveys to specify the exact frame profile, glass type, and hardware finish for your project.
Essex Heritage Specialist
Born and based in Essex, we understand the character of period homes across the county — from Victorian terraces in Brentwood to period cottages in Epping — specifying timber-look profiles that satisfy conservation areas.

The Founder
Built on
London precision
Sam has spent the last four years working with windows and doors across London, overseeing multi-million-pound installations across various property types.
From listed period refurbishments to contemporary new builds, that experience shaped an uncompromising standard — for sightlines, for thermal performance, and for the craft of the install itself.
Having worked with individual materials in isolation, Sam founded Fenestral with a clear conviction: that modern UPVC, beautifully foiled, can now replicate authentic timber so faithfully that Essex homeowners no longer need to choose between heritage character and modern performance.
