About
Dukes Windows was founded by Alex Dukes and is based in Hemel Hempstead. We’re proud to provide homeowners across Hertfordshire, Buckinghamshire, Bedfordshire and North London with high quality windows, doors and conservatories, backed by exceptional customer service.
At Dukes Windows, we’re specialists in supplying and installing high quality windows, doors and conservatories. Built on decades of industry experience, we’ve created a company where quality, trust and exceptional customer service always come first.
From your initial enquiry through to the final installation, we manage every stage of your project with care and attention to detail. We work with trusted manufacturing partners and highly experienced installers to ensure every product is fitted to the highest standard, and every installation is backed by our comprehensive 10 year written guarantee.
We’re not driven by high-pressure sales or unrealistic discounts. Instead, we focus on honest advice, transparent pricing and delivering the right solution for your home. It’s a straightforward approach that’s built on professionalism, reliability and treating every customer’s home with the care and respect it deserves.
From the outset, we’re open and transparent. We’ll give you realistic lead times, honest advice on whether uPVC or aluminium is the best solution, and if we’re not the right company for your project, we’ll tell you. We believe that’s how we would expect to be treated.
Every home is different, which is why every project deserves the right solution. Whether we’re installing windows, doors or a conservatory, we take pride in delivering exceptional quality, expert installation and meticulous attention to detail. From the products we recommend to the finishing touches, we believe every aspect of your project should be completed to the highest standard.
Trust is built through professionalism, transparency and consistency. That’s why we communicate clearly, provide honest recommendations, keep you informed throughout your project and deliver the high standards we’d expect in our own homes.
