Welcome to Holtye Windows
Holtye Windows Ltd was established in 2007 by Thomas Attrell and has grown into one of the best-known home improvement companies in the East Grinstead area. What started with double glazing now covers windows, external and internal doors, soffits and fascias, warm roof insulation and conservatories, alongside full renovations, refurbishments and commercial building works.
Everything we fit is manufactured from modern, energy-efficient, lead-free profiles with high-security locking as standard, in a wide choice of colours and finishes suited to contemporary, rural and traditional properties alike. You’ll get expert advice, an honest opinion on what your home actually needs, and a free written quotation.

Why choose us
National companies sell from a call centre. We survey your home ourselves, fit it ourselves, and are still just down the road afterwards.
Our own surveyors and fitters handle every job, so you always know who’s turning up.
Free, no-obligation quotes with the price and specification in writing. No pressure, no gimmicks.
Certass registered, SafeContractor approved and fully insured, with a 10 year guarantee on every product.
Kitchens, bathrooms, roofing and full building works too, so you rarely need a second contractor.
Everything is surveyed and made to your openings, in the colours and finishes you choose.
Rated 10/10 from 149 reviews on Checkatrade, where we’ve been vetted members since 2014.
Energy efficiency
Old frames leak heat through the glass, the gaps and the frame itself. Replacing them is one of the most effective ways to make a house more comfortable and cheaper to run.
Modern, fully sculptured, lead-free profiles built to hold heat in and keep draughts out.
No more sweltering summers and freezing winters — especially with an insulated warm roof.
Sealed double and triple glazed units cut outside noise as well as heat loss.
We’re Certass registered, so every installation is certified Building Regulation compliant.
