"After seeing Channelglaze's full hopper thermal break windows at the Crick Boat Show, I knew right away my boat needed an upgrade — and I couldn't be happier with the decision. These windows are, hands down, the best I could have chosen. Compared to my old single-pane top hoppers, the difference is night and day: far better insulation, cooler in summer, excellent soundproofing, improved security, unbroken views, and premium aesthetics. I'm absolutely delighted with the investment, and my partner was so impressed, he upgraded all of his windows too. Channelglaze is a friendly, family-run business and it shows. Dave was incredibly helpful, answering all my questions and even resolving a minor issue with one of my portholes by designing and 3D-printing a custom component. That kind of service is rare. If you're looking for high-quality, thoughtfully designed boat windows — look no further!"

"Had a great experience with ChannelGlaze from start to finish. Dave P was very helpful over email at the design stage, patiently explaining all the options to me until I'd selected exactly what I needed. The windows were made on schedule and delivered on time. I've come back nearly a year later just to reiterate the same — it's important to know whether your window will last, and happily my windows (Thermal Break, full hopper, anodized frames) seem to be in just as good a condition as the day they went in. The difference it makes to the quality of life here on the narrowboat in winter is truly astonishing — I have no doubt I saved hundreds on heating costs this winter just gone. Highly recommended still, after a year."

"The single glazing and lack of thermal break window frames on my Sea Otter would unsurprisingly give the condensation problem. After many a conversation with Dave at Channelglaze, I decided on the full hoppers and portholes, double glazed and thermal break. Matt oversaw the measuring of the not so easy to measure arch windows and the subsequent fitting. I was pleased that the removal of the old, and fitting of the new, was achieved carefully without damage to the existing paintwork. They certainly look very smart and very well built and I am confident that all the benefits theories will be proven. I was very pleased and comfortable with all the exchanges with Channelglaze. My thanks to all concerned. Yes I recommend."

"Our experience with working with the Channelglaze Team on installing replacement windows and portholes to our Narrow boat has been 1st class. The knowledge provided and advice given was most appreciated and the quality of the windows fitted and materials used is excellent. Matt and Dave worked proactively around our fitting schedule and the standard of workmanship carried out on fitment was excellent. Very satisfied with the windows and ports installed and would highly recommend their services."

"Speaking directly with the owner made the process of deciding which type of window I needed for my boat so very easy and with confidence. After many discussions regarding the selection I received the new windows in the agreed time and now they are fitted the boat looks so much better. The windows have a simple and clean design and are very easy to open and close. I would definitely recommend this company to anyone looking for new boat windows."

"Great service from the start to finish, from making our initial enquiry to the fitting we received excellent customer service. All 7 windows fitted in one day, definitely recommend."

"So far so good but I haven't fitted the windows yet. Based on the service so far, it's all been excellent. Helpful & friendly. I would definitely recommend their measuring service, if nothing else but to identify any points to consider that we hadn't. Looking forward to fitting in the spring."

"Our new windows by Channelglaze are great, we chose thermal break windows with a tint on glass. Front and both sides done and fitted in one day."

"Our 4 windows on our old (1971) David Piper narrow boat were replaced by Channelglaze nearly two years ago. The standard of both workmanship and quality of products were excellent. Since fitting we have experienced no issues whatsoever and we're delighted that we chose Channelglaze to undertake the refit on our behalf. I highly recommend giving the company a telephone call should you be considering having any windows replaced on your own narrow boat."

"Massive thanks to Matthew, Dave and Kevin. It was a few years ago when I set out to refit my boat that I decided when it came time to redo the windows, Channelglaze. And when I finally got around to it, they did not disappoint. The windows are absolutely stunning, and exactly what I wanted. One of the 10 windows had a hiccup, but they collected it the same morning and fixed it immediately. Top-notch service, incredible windows, highly recommend. 11/10."

"I am so pleased with my new windows in my narrowboat. I visited the showroom where Dave was so friendly and helpful without being pushy at all. I fitted the windows myself following the extensive printed instructions and the YouTube video link. Can't wait to see how much warmer I am in winter!! Thank you so much."

"Channelglaze were excellent in providing a professional service throughout my dealings with them, from initial discussions at Crick Boat Show to having the very good quality end product ready within their time estimate for me. Their aftercare has been excellent also. A very happy experience that I would have no regrets in recommending to other boaters."

"Windows look amazing. Team were extremely friendly and worked very hard to finish when we had issues that made us run over time. Had a small problem with one window but they dealt with it promptly. Have recommended them to friends."

"Our new windows have totally transformed our 23 year old girl. We have had so many positive comments and are so proud of our choice. Thank you, Channelglaze. Highly recommended as such a helpful company."

"Great service guided throughout from quote to completion. Had issue with one window, contacted them and sorted without fuss. Would use again."

"Channelglaze gave me good advice on the specification, finish and self-installation of thermal break double-glazed units in my 57 foot narrowboat. I especially liked the way that the opening windows were fully removable and that has been a real boon during the hot days of spring and summer."

"I had great service from Channelglaze. All the windows fitted perfectly, were ready on time and retain the heat in winter whilst being removable in summer."

"Guys were absolutely brilliant, difficult windows to remove due to Sea Otter using really strong adhesive. Great product, well done."

"We at Perrydale Narrowboats have always placed our orders with Channelglaze, and can honestly say they are faultless. Orders on time every time, and a privilege always doing business with them."

"Fantastic service, really helpful, excellent job done. Can't recommend them enough."

"Great service from start to finish."

"Great product together with great customer service."

"Dave, Matt and the whole team were great to deal with through the whole process. They communicated clearly to us from our initial enquiry, through the measuring process to the removal of our old windows and the fitting of our warm, waterproof, condensation free new ones! We are really pleased with the outcome and would recommend them to anyone thinking of new windows for their narrowboat."

"What a fantastic job done by these guys — they came and did it in a day in my marina at the price I was quoted. Clean, efficient thermal break windows, no condensation and the boat is absolutely toasty. Wonderful job lads, thank you so much."

"Excellent products and excellent service, I couldn't recommend Channelglaze more highly!"

"A very satisfactory experience with Channelglaze Ltd. The team handled the work with professionalism maintaining clear communication and a well-structured approach throughout. Every stage was managed with care ensuring the job was completed smoothly. The finish reflects strong workmanship with everything installed neatly and to a high standard. A reliable and well-organised service worth considering."
