The team's customer service was outstanding, making the entire experience smooth and enjoyable. I highly recommend their services to anyone considering secondary glazing! I can officially relax in my home with my family with warmth and no more outside traffic has virtually gone and save money on my heating bills.
The tension to detail is outstanding and you wouldnt even know the windows have been installed. Thanks you again to all the team at Invision Seconday Glazing 5**** Kind regards, Andrew Wilkins
His quote was 20% cheaper than other quotes we got for the same product from the same manufacturer. We chose low-e glass (as it was primarily for heat retention), with vertical sliders and tilts for our sash windows. Once we paid the deposit, we were told it would take approx. 5 weeks for manufacture. Almost to the day, Aaron called to say the windows were ready and booked in the installation. Steve and Connor came to install the windows shortly after.
They did an excellent job, turned up on time and took their time to get the perfect finish. They showed us how everything worked, then came back the following day to fix our curtain poles and boxed it out nicely so it would match the secondary glazing boxing. We have noticed a huge difference with our heat retention - our house now stays warm through the day and night and it has also massively reduced sound from the road outside. Further, the windows look GREAT, so much better than we expected, we think it's actually improved the overall look of our windows, as it's framed them really nicely - something we were a little worried about prior to installation. Highly recommend Invision Secondary Glazing, a company with real integrity.
They knew exactly what we wanted and did a fantastic job at working with us. The service from this invizion has been excellent throughout the whole process, starting with Aarons survey to installation. I will also add the installation team were very helpful, polite and tidied up any mess during and after installation. I thoroughly recommend this company and their products. Ps: enjoy the chocolates!
That was no easy job, with 11 windows to install some complicated aspects, but they were here working for a full 12 hours. (before setting back off home!) The result is as good as I could have hoped for. We have a period cottage, with irregular openings and uneven rebates and I was concerned about how the units may fit and how they may look with our Georgian windows.
In fact they fit and look excellent and are incredibly discrete. I could not recommend these guys highly enough. In addition to being extremely competent at what they do, they are delightful to have around, very thoughtful and they tidied up exceptionally well. Once again very many thanks for a great job done.
We can finally have a good night sleep and enjoy relaxing time in our home, plus we have cut back on the heating bills within the last two months because of the secondary glazing. I would recommend Invision glazing to anyone suffering from noise and wanting to save money on the heating bills. Outstanding workmanship 5
