Double Glazing Quotes Hertfordshire

High Quality Double Glazing

More and more homeowners in Hertfordshire and London are upgrading to double glazing to help make their homes energy efficient. Modern double glazed windows are significantly more energy efficient than single glazed windows or even antiquated double glazing styles. This helps keep heat retention levels high inside your house and, as a direct result, could save you money on heating bills.

Ordered and fitted front and back doors. Big thanks to Paul and his team. Pleasure to deal with them all from, quote to installation. Always got back to me quickly and were flexible and reliable, which was handy when I was working. Sensible quote and very happy with the fitting. Feels like a different house! Recommended.

Christine Boon

I had my double glazing fitted by O'Shea Glass and Glazing. Very satisfied with their services. Competitive price, and a very reliable company. Boys were very hardworking from start to finish. I will absolutely recommend them to all my friends and family! Thank you!

Fin Matthews

I was looking for someone to replace my windows, so I found Paul at O'Shea Glass and Glazing, and his level of service was excellent right from the first phone call. The quality of the windows was also top notch, and I noticed the difference straight away in terms of their thermal properties. I would highly recommend O'Shea glass to anyone looking for good quality windows, professionally fitted, and a good price.

After dealing with other companies and wasting my time, I am glad my friend has recommended O'Shea Glass and Glazing. They have done my kitchen splash backs and shower screen. Excellent service, would definitely recommend them!
