What Our Customers Say

The Happy Window company has provided an excellent service at an excellent cost, replacing all our doors and windows. In particular they have provided a bespoke arrangement for the front door. Paul, the installer was friendly, efficient and consulted us at each stage of the installation to make sure that we were happy. When he had finished he cleaned up and ensured that all was to our satisfaction.
