Every review below is a verified Checkatrade review from a real customer. We've put them all here, including the ones that mention Jak being two minutes late.
JBC windows were an excellent choice, replacing 4 window sets (one of which a full bay timber sash like for like bespoke replacement) and 1 new door in 3.5 days of work to a very high standard. No making good required only painting as normal. Fantastic personal service from experts in the field - would recommend and use them again
Very happy with the work that took place, the price was the best out there with my new front door fitted within in an hour and old door removed. Very polite and swift, good service all round.
Jak & Callum made a superb job of removing an old DIY porch and replacing it with new opening windows, door and tiled roof. The UPVC frames and trims are excellent quality and everything is sealed to perfection, using lead where appropriate (not some cheap adhesive tape!). They also installed a new small front porch in the same manner. I've already asked them to quote for another project.
Communication was good. Arrived on time for inspection but 2mins late for install. Thorough as far as mess and clearing concerned. I cannot fault any part of their work. In and out in less than 3 hours. Our plasterer builder commented, 2 days later, they had done an excellent job with a good quality window. I would not hesitate to use their services again.
Work carried out with no fuss and to a good standard. Friendly and knowledgeable team. A good experience
Jak and Callum were fantastic! Great comms, always on time and worked unbelievably hard from the moment they arrived. Will definitely use them again and highly recommend!
Great communication from the start, very reliable, friendly and professional. High standard of work completed including clear up after. Would definitely recommend.
Jack and Callum were exceptional from start to finish. They were punctual every single day, worked quickly efficiently and effectively. They were meticulous in detail and tidied up after every visit. Highly skilled and jovial whilst on the job, if you are lucky you might get to hear them singing along to Smooth Soul Radio.... The perfect feel good listening to music and watching our house come alive with their work. OUR WINDOWS / DOORS ARE ABSOLUTELY AMAZING!! I highly recommend their services. A fantastic service
I recently had Jax from JCB Windows Limited come to replace the window panes in my bedrooms and kitchen, as well as fit a brand-new side light next to the front door with glass above it. The results are absolutely stunning – I honestly couldn’t be happier! Jax and the team were professional from start to finish, extremely helpful, and went above and beyond to make sure everything was perfect. The workmanship is excellent, and the new fittings have completely lifted the look of my home. I would highly recommend JCB Windows Limited to anyone looking for quality work and outstanding service.
I needed some double glazed window panes replacing on a third floor flat and was struggling to find someone who could do the job without hiring scaffolding or hydraulic platforms. Jak got the job done! The new windows panes look great, and they cleaned up and hoovered once done so you can't even tell anyone was there. Excellent communication and service from the team, and I've recommended them all my neighbours.
Jack and the team were very quick to respond and managed to replace our 2 velux windows super quickly. They did a great job and we’ll definitely use them again!
Did what was required, great customer service, and a speedy response to my query. Asked for photos- instead of making a blind guess. Very polite and professional-They came, saw and conquered and were very nice guys. I would use again and recommend their services, no cowboys, obviously highly skilled and knowledgeable in their profession. -And competively priced. Thank you- for doing a great job- and more importantly ur customer service and expediency was on point.
I definitely recommend JBC windows! I've used them multiple times over the years during our home renovations. Jak, Callum, and the rest of the team are super informative and provide great advice on the various window and door options out there. I've always found them to be reliable, and they work really hard, keeping their work areas clean and tidy, always cleaning up after themselves.
The JBC team were fantastic. They were very responsive, great value for money, and fixed our window issue within a few days of me reaching out to them. Would highly recommend and will definitely use again.
Jak and Callum installed our new patio doors and side windows quickly and efficiently with minimal disruption. They left everything clean and tidy and were very pleasant to deal with. We would certainly use them again.
Responded to my request for quote for repair of upvc fanlight window very quickly. Turned up by appointment to carry out repairs the very next day. Very efficient, helpful and friendly. Would definitely recommend.
Responded straightaway to my request for the work. Turned up punctually. Very friendly and helpful. The job was completed very efficiently. Would definitely recommend.
very happy with the service received. swift reply and constant communication kept me very reassured. was so lovely to meet Jack and Callum
Callum and Jack installed double glazed windows, bifold and a roof lantern. The work they carried out was to the highest standard. Communication was excellent at all stages of the project with zero issues.
JBC Windows were very professional, reliable and carried out high standards of workmanship in my home. I have used the services of JBC a few times now and I’m am so pleased with the results and improvements to my home. I have had full double glazing throughout, new front door and porch, large lantern in my kitchen extension and beautiful aluminium bifold doors. The quality of the windows are excellent, the team are very friendly and trustworthy and importantly the services they provided were very competitive on costs. Thank you JBC you come very highly recommended. * * * * *
I cannot tell you how happy we are with the fabulous service we received from Jak and his fab team. Nothing was too much trouble. A real pleasure to have an amazing team to do our work Would recommend their outstanding work to everyone.
Outstanding installation from JBC Windows Ltd. Second time we've used Jack for brand new UPVC sash windows for our Victorian house. On time, extremely fast, super friendly and reliable. He is the best tradesperson we've hired throughout our renovation - they cover your belongings, protect your floors, clean the areas afterwards fully, remove rubbish, and give you your mugs back! Gorgeous windows/french doors - and competitively priced. We've recommended him to neighbours and they have booked in for window replacement too! Thanks Jack and Callum :)
I was really impressed with the service I received, Callum and Jak took the time in providing me options for my home improvements, they were professional, careful and cleaned up leaving no mess. I was nervous with removing existing patio doors replacing with stunning bi-folds, they made it look effortless and it has transformed my living space opening up the inside to the outside. I was so impressed they have also installed a new porch and replaced my old tired facia and soffits. It’s rare to find workman that take pride in their work and are honest and reliable. Highly recommend.
Callum installed the glass for a cat flap, he came and measured the glass and then popped back with the new glass and even helped me install the cat flap instelf which I bought. Very happy!
Had all my windows replaced including 2 bay windows. Excellent service from Callum and Jack they were on time, tidy didn’t even need to do any making good internally. Very happy with the service
Professional, responsive and great attention to detail!
Highly recommended true professional
Work is yet to be carried out but so far the men have spoken to have been very helpful and have beat every price I have been quoted.
Callum and Jak were extremely professional taking their time to listen to our requirements and suggesting improvements on what we had originally planned. There was no pressure and their prices were very reasonable in comparison to other quotes we received who took ages to come back with their quotes and felt like we were being rushed into getting the work done. We ended up using the guys to knock out existing patio doors and installing beautiful bi-fold doors. We then used their services for porch and facia and soffits. Highly recommend, lovely polite and reliable guys.
Callum and Jak completed my entire house for all windows inc a bay window and door both front and back replacement. They were very professional throughout the entire process, they worked efficiently and even took away the old windows and doors which was a bonus. Mindful of neighbours and always arrived on time! Great company and have recommended them to my neighbours who have complemented me on the finished result! Thank you Callum and Jak again
We hired Callum and Jack to instal new windows in our property as well as new guttering and suffixes. They did an amazing job, we are over the moon with how it looks and would highly recommend them to anyone looking for reliable and hard working tradesman. Time keeping was excellent and they were both very respectful and professional throughout.
Jack and Callum were so incredibly professional. On time, answered all my questions super quick and were very reasonably priced for an incredible finish on my bifold doors!! They also installed my plantation shutters where someone else failed me and they were able to do that last minute. Can’t recommend enough!
Callum & Jack have done a few jobs for us over the past few years, polite but honest grafters. The quality of the work is always top tier, they're proper lads that get stuck in. Regards Andy
