Double Glazing
Our double glazing solutions enhance thermal efficiency and security for homes and businesses. Using high-performance Eurocell profiles, we install uPVC, aluminium, and timber windows with options for triple glazing. Each installation includes expert fitting and a 10-year insurance-backed guarantee.
Conservatories
Bespoke conservatory designs create additional living space with year-round usability. We offer Edwardian, Victorian, and modern styles, incorporating advanced glazing and self-cleaning glass. Full installation includes structural support and customised finishes to match property aesthetics.
Composite Doors
Durable composite doors combine security and style with a range of colours and finishes. Manufactured in-house, our doors feature reinforced frames and multi-point locking systems. Customers can customise designs to suit traditional or contemporary properties.
Bi-Fold Doors
Space-saving bi-fold doors provide seamless indoor-outdoor access. Available in aluminium or uPVC, they feature thermal breaks for energy efficiency and come with low-threshold options for accessibility. Installation includes precision-aligned tracks for smooth operation.
Skylights
Skylights maximise natural light in flat-roof properties. Our units include temperature-controlled glass and self-cleaning coatings for low maintenance. Available in 2 or 3-bar designs with frame colour options to complement interior and exterior decor.

We have used Diamond Windows for our patio doors, composite front door and now replacement front windows. Each time they have performed in a friendly and professional manor. There is no doubt that we can highly recommend Jill and her team for any work they carry out. Next year we intend to replace our rear windows so have no doubt that we shall be in contact again.

We have used Diamond windows for all of our replacement windows and soffits. They also installed our wonderful new conservatory. Their service is first rate, as are their products. I highly recommend Diamond Windows.

HAPPY CUSTOMER WOULD RECOMMEND....Fantastic service from start to finish. No pushy sales, and the fittters are brilliant! Don't be ripped of by a company called 1st Home Improvements who want to charge 18,000 or 6000 if you sign up on the day! People deserve to know who the cowboys are.

Very keen pricing and the quality of the Windows is of the highest standard as are the fitters who work quickly and cleanly. Family run business where the mother and son do the home visit and measure up, the Windows are made in their own factory in Maldon. They even organised someone to do our soffits too!

Have just had a new front door with side windows fitted. Mike could not have been more helpful with his advice from the first initial contact. Very keenly priced. Excellent product which has been fitted extremely well. The fitter was polite and very hardworking and left everything clean and tidy. Exceptional service throughout from this local family firm who we would highly recommend without hesitation.
