About Us

Established in 1998, and with many years of experience amongst our key personnel, we offer a decade of expertise in the fabrication and installation of windows and doors, and with our first 10 years of trading, we have completed close to 1 million units installed.

We work across London, East Anglia and the whole of the South East corner of England, providing a personalised, reliable and attentive service to valued clients including new build contractors and property management companies.

All of our products are manufactured following safety and governmental quality standards in-house at our facility in Halstead Essex, where we are in the process of expanding to include the growing demand for our Aluminium products.

We provide a one stop solution for your glazing needs – carrying out excellent quality installations across entire new build housing developments with the confidence  that our team can handle jobs of any size.

The company demands excellent qualifications from all of the staff who undergo comprehensive health and safety training, NVQ’s in window installation and hold Construction Skills Certificates from the CITB.

Denver has a comprehensive in-house Environmental Policy.  In a world increasingly concerned with the environment, we are working towards goals such as carbon neutrality by gradually introducing environmentally friendly policies and methods.  So far we have reached 100% recycling of paper, card, plastic, glass and aluminium wastage through the use of in-place recycling schemes.  We also now receive as many of our materials and supplies as possible from local sources to reduce road miles and are working on further measures to achieve our goals.

Our reputation for consistency has won us many high profile clients with reputations for quality.  See what makes our products and services so attractive and CONTACT US TODAY to discuss your needs, we aim to meet your requirements first time.
