Tri Tec Windows
We are FENSA approved installers, specialising in the design and fitting of stylish, low-maintenance and energy efficient UPVC windows, doors and conservatories in Chelmsford and across Essex. Tri-tec Windows is a well-established, family-run company, specialising in high-quality workmanship, first-class customer service and competitively priced UPVC windows, doors and conservatories for homeowners across Essex.

We are a leading installer of stylish and low-maintenance UPVC doors that bring the outside in. At Tri-tec Windows, we believe passionately in the aesthetic and practical qualities of PVC-u glazing. Unlike timber windows, which require regular patching and filling and run the risk of rot, PVC-u glazing is low-maintenance from the day of installation and built to withstand the most severe weather conditions.
Services
We are FENSA-approved installers of UPVC windows, doors and conservatories in Essex, serving trade and domestic customers with genuine kerb appeal. Note: FENSA certification does not cover conservatories, repairs, porches, new-builds, extensions or commercial premises. At Tri-tec Windows, we believe passionately in the aesthetic and practical qualities of PVC-u glazing.
Ready to explore the design possibilities of our low-maintenance PVC-u windows and doors for your home? Or looking for a dependable supplier to install new windows, doors or conservatories for your valued clients? Arrange a free initial consultation to discuss your requirements, allowing us to provide an accurate quotation for bespoke Tri-tec solutions that add visual and practical appeal to properties.
At Tri-tec Windows, we specialise in providing A-rated UPVC windows that offers unbeatable style, durability and security for homes throughout Essex. We work closely with contractors and tradespeople across the county, supplying and installing bespoke windows for their clients featuring the latest double-glazing technology.
We understand that it's important for your windows to complement your home's architectural features and your personal sense of style. Depending on your needs, our UPVC casement windows can be either top-hung opening or side-hung and come in a wide range of combinations, sizes and colours. You can choose clean-cut chamfered beading or a more decorative sculpted ovolo finish, with internal or external Georgian bars if they suit your scheme.
Like the name suggests, these windows offer a smooth, flush fitting appearance when closed, with no lip between the outer frame and the sash. The result is a modern, streamlined look when finished in Grey that's growing in popularity, especially in more modern home designs. For a more traditional timber look choose a woodgrain finish to perfectly complement the aesthetics of your property.

If you want your home secure then an endeavour door fitted by Tri Tec is the way to go, the quality and build of the door is superb, locks are some of the best and fitted perfectly. It may cost you a bit more, but how much do you value your security, I would never use a high street window company again.
Just you tube or google Endeavour doors, you will see the benefit of these doors and they are fitted by Tri Tec a local company.

Tri Tec were quick to respond to all communications and scheduled appointments were attended on time. The sales guidance and various door options were clearly explained to me. The installation team arrived on time, they were polite and tidied up any mess which they created during the replacement of our front door. The Endurance door product that we selected appears to be well made and I can’t fault the overall service. I would recommend Tri Tec to anyone.

I would recommend Tri Tec. From my initial contact for a quote via email, to the survey and then installation of the replacement windows, great service.

We are very pleased with the windows and doors that Tri Tec supplied and fitted. They were well organised, professional and helpful with the quotation and survey and arrangements for the fitting. The fitters were also well organised and worked methodically taking care not to damage any decoration and making strenuous efforts to clean both the windows and the rooms on completion.
