About Us

Established in 1993 and specialising in West Cornwall, Pro-Line are the leading company in the area for all your double glazing needs. 


With in excess of 13,000 local installations you can see our products in and around every corner of the local towns and villages across the West Cornwall peninsular.

All windows and doors are fabricated using high quality PVCu profile and hardware, along with the latest energy saving glass, including Argon gas filled sealed units. Our skilled installers work to high standards to achieve an installation which you will be proud of. As a free service we remove and dispose of all old window and door frames. All of our work is Certass certificated as required and comes with an insurance backed warranty.

Our History

Our company proprietor, John Elsey, gained 10 years experience working for a large window and door manufacturer. In 1993 he decided that the time was right for West Cornwall to have its own local double glazing company. 

Our mission from day one has been to offer our customers high quality products, expertly installed at fair prices. This principle has carried Pro-Line forward to where we are today - the number one local supplier of windows, doors & conservatories in West Cornwall.

An Unrivalled Service

When you’re looking for replacement windows, residential doors, or a new conservatory, we are happy to offer you a free quotation. You will receive straightforward advice with no gimmicks. We will also offer guidance regarding design, which must take in to account rules regarding fire 'egress' in habitable rooms. If you are looking to place your business with an established local company who offer high quality products and service, we will exceed your expectations, and you will find our prices attractive.
