A homeowner contacting them would typically discuss the type of windows or doors they need—such as uPVC, aluminium, or timber—and request a free, no-obligation quote. The company would arrange a survey of the property to take accurate measurements and discuss any specific requirements, such as double or triple glazing, security features, or energy efficiency ratings. They would also go over the installation timeline and any necessary preparations.

When speaking to them, it is advisable to ask whether they are FENSA registered, as this certification is required for replacement window and door installations to comply with building regulations in England and Wales.
