Established in 1989, Harp Windows is a family run company manufacturing and installing high quality replacement windows, doors and conservatories. Over the years, we've worked hard to build a reputation for professional integrity, efficient customer service, high quality products and value for money. Customer satisfaction is paramount to Harp Windows, we do everything possible to ensure our customers are delighted with their new windows, doors or conservatory. We are fully endorsed by WHICH as a Trusted Trader, plus you can read many reviews about us on Checkatrade - and for further peace of mind our customers are always welcome to visit us at our showroom in St Albans Road Watford, or our factory in Watford, where we manufacture many of our products.

From the sublime to the simple, we can make your conservatory dream become a reality. From a modest lean-to design to a stunning Victorian classic, the choice is yours. A cost effective and enjoyable way to add light and space to your home, a conservatory can offer a welcome retreat with resplendent views of your garden and the great outdoors. And, because most domestic conservatories are exempt from mainstream Building Regulations and Planning permissions, they can be installed with the minimum of fuss.

By using the latest modern materials, our long lasting highly durable doors need very little maintenance, boast excellent thermal and soundproofing properties and extremely efficient security features.
