Visit Us

As Dunster House Ltd started out as a specialist uPVC windows and doors manufacturer, we would like to think that we have been developing the best windows and doors in the market for our garden buildings. Our Windows and Doors has been developed over a number of years to provide our customers with the best and most secure option available on the market.

High Quality, Low prices

We are able to keep our prices low, and our products high quality because we make all our windows our self at our Bedford factory.

That's why our customers keep coming back for more, year after year.

With our own work force, vehicles and manufacturing capability we are never reliant on outside agents to uphold the standards we've set.

And because we sell direct, with no middle man, our name is synonymous with simply unbeatable value for money.

Why not visit us ?

A selection of the range we sell is always on display at our Bedford branch:

Dunster House,
Factory 1,
Caxton Road,
Elms Farm Industrial Estate,
MK41 0LF

So, if you want to come and check out the colours and quality of what we sell, you're very welcome.
