We’re proud to offer a comprehensive guarantee that at 10 years, is double the industry standard.

Setting the standard

Windows, doors and living spaces are a big investment. These products aren’t an everyday purchase, and they need a guarantee to reflect that outlay.

We provide a simple but comprehensive guarantee that protects you in the long term. The TradeMark guarantee lasts 10 years. And with decades of history behind us, you can be assured that we’ll be there for you for years to come.

Our Guarantee

Labour & Repair

Unlike other companies, our 10-year guarantee covers associated costs with both parts and labours. So if any maintenance is required, it won’t cost you a penny.

Independent Inspections

To finalise our installations, we ask an independent building inspector to visit and ensure that it conforms with all current building regulations. Just another example of why TradeMark protects you in ways others don’t.

Installation Focus - Fitting
