Quality conservatories, windows and doors in Letchworth, Baldock and Stevenage

Hertfordshire Window Company Ltd is an independently run double glazing business established over 35 years ago.  Over this time we have grown into a leading manufacturer and supplier of high quality uPVC windows, doors and conservatories.

As a FENSA registered company, we manufacture all our uPVC frames in our 10,000 sq ft factory in Letchworth Garden City, ensuring the quality meets and exceeds British Standards. We use Pilkington glass in all our double glazed units, again for quality and reliability.

For security we use a shoot bolt, multi-locking system. Our uPVC frames are internally glazed and our doors are fitted with 5-cylinder dead locks as standard, which meet the requirements for insurance approval. All of this is implemented to give you a high quality, reliable and secure double glazed installation.
