A very professional job

From the moment I sent the text to request a quote to have new windows and doors fitted, Jon and Joe were the ultimate professionals. They visited promptly and, once we had agreed on the style and measurements, they were quick to order the materials and get a fitting date in the diary. On site, they were friendly, efficient, keen to ensure that everything was to my satisfaction and extremely tidy! I am so pleased with the result and would highly recommend them to anyone considering their services.

We decided to us JC Friend & Sons as we were recommended to them by family. What a good choice that was from the start, we were impressed with the choices given by the surveyor and follow up drawing details to show us what we were getting. A date was set and the fitting was carried out with ease by two of the most polite installers I have ever met.There was no impact on us at all, we could have gone out and come back to new doors in place of our old ones. Many thanks John,Jon and Joe.

Outstanding service and quality workmanship from start to finish

We recently used J.C Friend & Sons Glazing Ltd for a full window replacement across our house, including additional windows as part of an extension, and I honestly couldn’t recommend them highly enough. Jon and Joe were brilliant from start to finish. They’re genuinely nice, down to earth people who clearly take pride in their work, which makes a big difference when you’ve got a major job going on in your home. The quality of the installation is excellent, and the 5m wide Cortizo sliding doors they fitted are a real standout feature, they look incredible and have completely transformed the space. What really impressed me was the turnaround time, everything was done quickly and efficiently, without cutting corners, which is pretty rare. This isn’t the first time I’ve used them either, they’ve done work on previous houses I’ve owned, and I’ve always had the same great experience. Consistently reliable, high quality work, and a pleasure to deal with. I wouldn’t hesitate to recommend Jon, Joe and the team to anyone looking for glazing work.

We recently had two windows and a new door fitted and couldn’t be happier with the service we received. Jon and Joe arrived exactly when they said they would, which was really appreciated, and carried out the work efficiently and to a very high standard. The quality of the installation is excellent, and everything was left spotless at the end of each day — they cleaned up exceptionally well, which made the whole process smooth and stress-free. We’re very pleased with the finished result and would happily recommend them to anyone looking for reliable, professional glazing work.

From the initial enquiry to completion John and his sons were great. We had replacement windows throughout the whole house. We were given excellent help and advice as we made our design decisions. The installation went seamlessly. The house was left tidy at the end of each working day, and John's sons, who did the installation, even pointed out some small unrelated issues which we would need to deal with. We are delighted with the quality of service we received, and would have no hesitation in recommending them.

Fitted our home with new windows & doors to a high standard. They worked very well, completing work within specified time period. Disruption kept to a minimum & always cleared up at the end of each day. They took all the old windows & doors away for recycling.

The company was highly recommended by neighbours who’d had a great job done on their front door and porch windows. After getting in contact, Joe came round to take a look, then quickly came back for measurements and details and was so friendly and helpful at all times. They helped us choose the front door and porch windows we wanted and even pointed us towards other examples locally for an idea. They fitted us in as soon as they could and the actual job was very speedy with minimal disruption. Communication was perfect and when we had a little teething trouble with the door both Joe and Jon were round in no time to help us fix it. We’re so happy with our new door and windows and have recommended them to our friends and family.

J. C. Friend & Sons installed four windows and a French door for us and completed the job to a fantastic standard. Jon and his brother were always attentive to making the task of removing and installing the units as quick and stress-free as possible, going out of their way to deliver high quality of work in a convenient fashion. They also provided some really useful advice relating to the ongoing work we're doing on our home and how best to arrange future window and door installation around it, in a way that demostrated that they had our interests at heart. We wouldn't hesitate to use J. C. Friend & Sons again, and thoroughly recommend them.

JC Friend and Sons is a family business and have replaced all our doors and windows over the years and installed 2 x French Patio Doors in early Oct 2004. The workmanship was excellent. They delivered and arranged work when they said they would and were on time and to budget. The two young men who carried out the installations were very professional and tidy! I would happily recommend their workmanship and professionalism.
