Double Glazing

Installing double-glazed windows in a property improves the aesthetics and makes the home more energy efficient. Double glazing is also an investment in security and the value of your home.

Double glazing adds about 10% to the value of your home. Replacing old windows with double glazing can also save between £65-£110 per year on energy bills. Modern double-glazed windows also come with upgraded locks and security features.

Double glazing is one of the most popular home improvements for all these reasons. Homeowners in Cornwall have trusted Best Glaze for over 20 years to upgrade their windows, doors, and conservatories to attractive, energy efficient double glazing.

When looking for a company to help with a broken window, I did a bit of research before making contact with a couple of local companies. Best Glaze had very good reviews but not only that they were very helpful from the very first phone call I made. Jay turned up at every appointment on time and answered all phone calls/emails very quickly. Best Glaze have proven to be very reliable and the service given has been excellent. They were also the only company that were able and willing to help us in a short time frame. I have no hesitation in recommending them.

Outstanding service from Jay. He understood our situation, gave us various options and repaired a leak in our conservatory quickly and efficiently. He was a pleasure to have here, very friendly and helpful. We would have no hesitation in giving him 10 out of 10 and would recommend to all.

We contacted best glazeto look at a 5 year old conservatory which was leaking. Jay and Tom quickly explained the reason for the problems and e booked them to do the work. The seemed very knowledgeable compared to other companies. We went for a partial solid roof plug two roof windows. We were very happy with the work carried out. We were very happy with the work carried out and amazing results. Conservatory is now dry and comfortably warm with new sills and guttering. It is like a extension of hour house. All work was carried out without serious mess and our lawn was carefully covered against damage. And unsuitable supporting wall replaced and insulated. Over all we are very pleased and would use their services again.
Many thanks

Great friendly service. We had a glass conservatory roof fitted. Very professional throughout and turned up exactly when they said they would. Perfect communication. Highly recommended. Will be in contact when we need the windows replacing!

My street door is looking great 😊 I would highly recommend BestGlaze

What to do when you suddenly can't get a double glazed window to close & lock
AND you live in a bungalow??????
Jay& Tom are highly skilled & experienced Glaziers who work efficiently as a Team.
Knowing their work from the past I was confident that they would solve the problem. Which of course they did.
Such is their attitude and diligence towards their work , that they then carried a quick maintenance check on a further 13 windows.
Thank you Jay and Tom

The guys carried out an amazing job fitting our replacement uPVC windows and doors, having a converted barn I don't think we have a straight wall in the house, added to that the original windows had been "strapped" which increased the difficulty in removing them. Innovative ideas ensured that the new windows and doors fitted perfectly and looked "right".
The work was carried out with consideration to our home, ensuring that no damage was caused. The work was strategically planned with our input and Jay and Tom were always happy to work on in order to ensure the minimum of disruption to our lives and work areas were always left tidy.
I would have no hesitation in recommending them to anyone considering having work done.

Best glaze were very professional. The installers produced a top quality finish with no cutting corners. They made sure their work area was neat and tidy by keeping tools and sharp objects safely on my property and in their work vehicle, which was very appreciated due to having young kids at home. The level of finish was nothing less than outstanding! I would definitely recommend them and if needed I would not hesitate in booking more work in with them again.

Excellent customer service. Good time keeping. Always updates on work to be carried out. Very clean and tidy even when doing the muckiest of jobs. Would highly recommend. Very pleased with the work carried out on my 40 foot flat roof conservatory.

Customer Testimonials

Front and back windows fitted Jay and his team were great all around. (Communication/price and specially the workmanship, which was perfect, very satisfied with the end result. A great deal of consideration also given to any mess made inside and out, leaving the property spotless. Highly recommend.

We had a replacement conservatory roof from Best Glaze after doing research online and deciding we wanted an Ultraroof.
Best Glaze was one of the most highly rated suppliers and installers of the ultraframe conservatory roofs and after having had ours done, its easy to see why.
Our conservatory had a polycarbonate roof that was leaking and was too cold in winter and too hot in the summer to use as a room, so we decided on a solid tiled roof.
The difference is amazing, the conservatory actually feels like a proper extension now which is exactly what we wanted. We would not hesitate to recommend, first class.

I have just had the leaky polycarbonate roof replaced by Jay and his excellent team on my 15 year old conservatory. I chose the Ultraroof system and their brochures don't lie, it has made such an improvement! Despite the extreme 40% pitch of my roof Best Glaze nailed the job during the coldest and windiest week of the year so far, and they still managed to smile! Customer liaison was excellent and Jay is always available to discuss minor adjustments to the plan as they developed. I would recommend Best Glaze without question; you won't be disappointed!
