Mr R Knight

Westcott installed VELFAC windows and doors throughout our self-build project. They, and all the Westcott staff we’ve met, have been highly professional and very easy to work. I have no hesitation recommending them.

Paul, Wiltshire

Westcott Architectural Glazing installed Velfac aluminium windows, bi-folds and external doors right across our house refurb. They were friendly, responsive and knowledgeable – and explained things in terms we could easily understand. We have no hesitation in recommending Westcott.

Anthony, Cosham

I have had the pleasure of working with Jeremy and his team on numerous occasions and find them all to work to the highest standards and with the upmost professionalism. Having 25 years experience in the building trade as a plasterer myself I have experienced good and bad companies along the way. However Westcott Architectural Glazing is up there with the best of them and I couldn’t recommend them more highly than I do.
