Register GuaranteeAbout C&B Windows Ltd, Dunmow
When looking for a double-glazing company in Essex it is essential that you find one you can trust to offer a high quality, guaranteed service. Based in Dunmow, C&B Windows Ltd is a reliable and professional double-glazing installation and repair company with over 17 years of experience.
Double glazing has the potential to significantly reduce your fuel consumption by improving the insulation of your home and reducing heat loss via windows and doors; an investment which in the long term could save you a considerable amount of money. We provide a full range of double glazing, secondary glazing and triple glazing. We can provide services from replacement units to roof windows and patio doors. All of the units we offer are high quality and energy efficient whilst improving the style and value of your home. In the case of listed buildings we are able to advise on secondary glazing which is a cost-effective, non-structural alternative to traditional triple or double glazing.
In order to maintain our high standards and promote excellent service throughout our organisation, we are a fully FENSA registered company who offer insurance backed guarantees with all our installations alongside our workmanship guarantees.
We offer a broad range of double glazing and secondary glazing installations and repairs including:
- UPVC, Aluminium, Timber Windows & Door Installations

Review by Ed Murray

"We couldn’t be happier with the work from David and his colleague James at C&B Windows. They installed ten UPVC sash windows and five casement windows in just four days – an impressive feat given the care they put into each one. They were punctual, professional and conscientious, leaving the house tidy at the end of each day. The quality of the installation is excellent, and the finished result has completely transformed our home. Great service from start to finish, with David always on hand to answer our endless queries – highly recommended!"

Corinne - Image 1 "I found C&B Windows Ltd through Trust a Trader and after getting a few quotes to replace the upstairs windows with double glazing then I decided to go with them. I liked that David was very professional and personable throughout the quotation and installation process. The works were completed, as planned, within the time scale given. David took care of the property thought the process, removing shoes and using coverings to keep everything clean. I am delighted with the new windows and would definitely recommend C&B Windows Ltd to others."
