Harrow Windows & Construction

Welcome! Please enjoy browsing our site, which is full of information about us and what we do. We welcome all comments and enquiries, so if we've inspired you, please give us a call! Who are we? We're a local independent family run business, specialising in the supply and installation of windows, doors, conservatories, and home extensions and general building work. We offer a wide range of top quality products to improve your home, all available in a range of materials including hardwood, uPVC and aluminium.

We're particularly proud of our conservatories, and our stunning range of bi-folding sliding doors. Our commercial contracts have included the installation of mirrors and glass walls throughout several branches of Marks and Spencer, including the Marble Arch and Kensington stores. We also work closely with major property developers and interior companies.
