Frequently asked questions
Which window material is best?
It depends on your priorities. uPVC offers the best value and suits most homes, aluminium gives slimmer frames and a modern look, and timber suits period properties. We are happy to advise at your free survey.
How much do new windows cost?
It depends on the number of windows, the style, the material and the glazing. We give a fixed written price after a free survey rather than a misleading average. Request a quote for an exact figure.
Are your windows FENSA registered?
Yes. Every installation is FENSA registered and certified as compliant with building regulations, with a certificate provided on completion.
