The windows and doors from Ace Double Glazing have excellent energy ratings, so they not only look wonderful but also keep your Tavistock home warmer. All of our products have double or triple glazing, which greatly enhances their ability to conserve energy compared to single glazing.

In double-glazing, an argon gas pocket is placed between the two panes of glass, trapping heat as it tries to escape from your home. By adding a third pane, triple glazing goes above and beyond to significantly cut down on heat loss.

Customer service is second to none!!!!

Could you please pass on our thanks to your whole team who have been excellent, customer service is second to none!!!! The gentlemen who fitted our door today are an absolute credit to your company and they have done a super job of fitting the door and tyding away.  They were prompt, courteous and on time.

Product was great

Can’t fault them. Product was great. Team was great. Acoustic glass is brilliant; so much quieter!

Realise that this is another Peacock Blue door. But, it is a lovely colour.

Many thanks Ace

We are so pleased with our two new exterior doors, from start to finish it has been a very professional and courteous service. The guys who fitted the doors have done an excellent job. I would definitely use Ace again, and would highly recommend them. They have great customer service and meet all our expectations.

Would definitely recommend Ace double glazing.

Our new patio doors are every bit as good as we hoped they would be. Sam and Chris have just finished and they’ve done a brilliant job. They were friendly, efficient and professional. The new door looks great and every bit of the old one was removed without a trace. And Sam and Chris made sure everything was clean and tidy before they drove away.

Very improfessional

A couple of months ago i had a new bathroom window fitted and i was so impressed by the quality and the professionalism that i saved up to get my patio doors done as they were letting in huge amounts of draft (think curtains blowing!). The guys came out and again did another excellent job. Im now saving for the rest of the house to be done. Thank you!

We have just had a new front door installed by Ace Double Glazing and we are totally thrilled with the quality and installation the company have supplied. The whole procedure of choosing the door to being fitted was straight forward and the company kept us informed at all times.
