What makes us different?

We completely understand why it’s so important to take your time before choosing the right team to carry out your next project, but we’re always on hand to offer free quotations and advice – not a disguised sales pitch, which is all too common across parts of the double glazing industry! Our goal is to understand what’s right for you and your home, and our friendly team will run through everything in great detail, suggesting the best windows, door or conservatory for you, your family and your home.

With hundreds of satisfied customers across Buckinghamshire, our installers are experts in dealing with wood, uPVC and aluminium windows, doors and conservatories. We are also FENSA approved and Guardian Warm Roof certified with full Public Liability Insurance.

Our journey to becoming Guardian Warm Roof Certified

Having been in the industry since 2001, we’ve witnessed some incredible technological developments in windows, doors and conservatories, however, there has been a sudden surge in Smart Roof replacements. It’s a sad truth that too many homeowners who invested in a conservatory 10, 20 or even 40 years ago are still yet to reap the rewards they were originally promised. Many conservatories in the UK are unused for large parts of the year because they’re way too hot in the summer and freezing during the wintertime.

We wanted to provide the best possible solution for customers seeking an upgrade to make their conservatory feel more like an extension that can be enjoyed all year round. The Guardian Warm Roof is the UK's official, LABC approved Replacement Conservatory Roof, and having trained to become approved installers, we’re now so pleased to be able to offer this solution to our broad range of customers in Olney and the surrounding areas of Buckinghamshire.

If you’re looking for a specialist in windows, doors, conservatories, glazing or security, we’d love to speak to you about your particular needs, and you can do so by calling the office on 01234 712242 / 01908 980068. Alternatively, you can send us a message using the contact form and we’ll be in touch with a reply as soon as possible.
