Tri-Tec: FENSA Approved Installers

At Tri-tec Windows, we believe passionately in the aesthetic and practical qualities of PVC-u glazing. Unlike timber windows, which require regular patching and filling and run the risk of rot, PVC-u glazing is low-maintenance from the day of installation and built to withstand the most severe weather conditions.

Whether you are a contractor or a homeowner, we’d love to hear from you. We supply and install PVC-u windows, doors, conservatories and lantern roofs to enhance the appearance and security of properties throughout the Essex area, underpinned by a 10-year insurance backed guarantee.
