we had Castle Windows fitted windows in September 2025. From the start Carl came out and did a thorough assessment and gave excellent advice. The windows were fitted by Nathan and Alan who did an excellent job. They also tidied up after fitting the windows. Very professional service from the start to the end. We would highly recommend Castle Windows without and hesitation.

They also repaired older window mechanisms that were installed by other companies as well as rectified minor glitches that appeared willingly and promptly. Superb company and really do above and beyond. Anywhere they can help, they do. Really pleased with the improvements made. So delighted with workmanship and the products.

Excellent communication, advice and service throughout whole process. Carl visited to measure up, discuss options and provided a quote there and then. Carl was very helpful, highlighted issues I hadn’t considered and uploaded various options onto my TV. This was very helpful in deciding which option to choose. Carl is hugely knowledgeable, experienced and listened closely to my requirements, with no pressurised sales. Carl has a small number of fitters who have worked exclusively for him for years. Castle Windows have a large number of positive reviews on Which? Trusted Traders, Checkatrade and Trustatrader. When I chose to proceed with the work, it was easy to agree a convenient installation date. The fitters, Nathan and Alan were punctual, polite, friendly, efficient and respectful of my home. The windows were expertly fitted and it was clear they both take pride in their work. It was a two day job, they were tidy throughout the installation and they cleaned up thoroughly inside and outside before leaving on both days. I am very pleased with the finished windows; they provide functionality and meet building regulations that the old windows didn’t and they look much more uniform and elegant. In short, Castle Windows fitted the windows to a high quality at a competitive price. If I need any further windows/doors fitted, I won’t hesitate in using them again and highly recommend them to anyone needing the same.

Initial contact was good. Arranged a time for a quote, and Carl was on time. Happy with the price quoted, so measurements were taken and a day was arranged for fitting. Fitters were on time and replaced my patio door with no mess left. Really pleased with the new door. Would recommend.

Excellent overall experience. I wanted a composite door fitted, my back door and six UPVC windows replaced, which included the main windows at the front of the property. When Castle Windows first came, a picture of my house was uploaded onto the tv and various windows and doors were added to help me make a choice, and decide if this was the right company for me. Very useful. I was contacted by the office a week before the installation to confirm the dates and time of arrival. The fitters, Billy and Josh, were first class, timely, polite and efficient. The windows and doors were expertly fitted, as you would expect. I was particularly pleased with how they managed the patching required externally around the windows, something that was left over from when the previous UPVC windows were fitted. It was very neat. They were tidy throughout the installation and cleaned up inside and out once the work was completed. I am happy to have chosen Castle Windows and am confident that the windows and doors have been fitted correctly. I love the new look of my house and have already had nice comments from a few of my neighbours.

Great communication and advice throughout the whole process. Selected Castle due to the quality of the windows/doors and a competitive price. No pushy sales techniques and gave me a price straight away, whilst others took weeks or didn't even come back to me. The fitters were friendly and clean/tidy throughout the 3 days. Would highly recommend Carl and his staff. Very pleased with the windows/door - they look great!

We decided to use Castle Windows again as we were impressed with them 5 years ago. Firstly, arranging an appointment was easy. Carl attended on the agreed day/time and talked us through what we wanted, especially with the replacement doors. We had French doors and we were walked through all the pros and cons of French, sliding, bi-fold etc. We decided and a date for fitting was arranged. I had a call the week before as a reminder/confirmation. On the day, the guys arrived promptly (Early actually) and started straight away. They were very keen not to make a mess and were very courteous. The speed in which they got the old windows and doors out was amazing. The new windows and bi-fold doors look amazing and we are very happy with them. Everything was cleaned up afterwards and the job was finished in the one day. I’d recommend Castle Windows to anyone.

We had a window changed into patio doors and we are extremely happy with the result. We got a quote very quickly, the work was booked in immediately and then on the day the guys completed the job carefully and speedily. They left the place really tidy and were courteous and considerate throughout. The communication with the company was good, the price was fair and we are very satisfied.

The above installation by Castle Windows was an excellent job done. The fitters were clean and friendly workers. Respectful of working in your home. The fitters work exclusively for Castle Windows which was important to us as we have had issues previously with contract fitters. Which means even if the product is good the quality of the installation is not! You can be very disappointed with the outcome. We managed to agree an amicable price after negotiation which we were more than happy with. Overall a great job.

From the day we got a quote to the day everything was completed Castle Windows have been amazing. Carl who came to quote was really friendly and gave the best advice he wasn’t pushy at all. The window fitters were on time friendly and tidy. The soffits, guttering, cladding and dry verge look amazing, the fitter was really helpful and explained everything we asked about. Although we won't need replacements for a while we would use Castle Windows again and would highly recommend. Fantastic company and fantastic staff.

We recently used Castle Windows to install new doors and windows throughout our detached bungalow. I cannot emphasise how happy we are with the finished result and the service we received. Carl was very knowledgeable and helpful, offering advice based on our personal taste and was able to provide a quote on the initial visit which was very reasonable. We were also able to see exactly what the windows we’d chosen would look like in our bungalow on the initial visit, thanks to some nifty software which rendered the property (with Windows installed). There were also absolutely no “hard sell’ techniques (which I despise), as Carl simply provided us with a quote and left the decision with us. Installation itself went extremely smoothly, thanks to two absolutely outstanding fitters (Billy and Josh) who were both really knew their stuff and were highly skilled. They turned up on time every day and worked extremely hard, even doing smaller jobs which were outside the provision of installing doors and windows. Their work was so neat and professional and they tidied up as they went along ensuring that there was minimal disruption. What was initially a four-day job, was completed in just over three days, due to how hard the boys worked and how good they were at their jobs. Absolutely outstanding service all around from a very professional company. I can’t recommend or rate them highly enough.

From the initial response to our enquiry to the completion of all the work carried out (replacement Conservatory with triple glazing and two replacement doors), Castle Windows have provided the most excellent of service. We felt Carl understood our requirements from the outset and he was also very thorough in carrying out the survey. We were given a date for the start of the work and this was held to. The preparation work completed by Ben ensured that our existing flooring and underfloor heating was completely protected while the work was carried out. Josh and Billy who carried out all of the construction work were polite, courteous and extremely thorough. Their work ethic amazed us, especially on the first day when they worked right into the darkening light to ensure we were both weatherproof ahead of incoming stormy weather and also secure with locks fitted. We could not thank them enough but hope they realised our appreciation. We highly recommend this company.

Castle Windows did an excellent job for us two years ago, when they replaced windows to the living room and main bedroom. Early this year, the dining room window began to give problems. It was installed 20 years ago, by another firm, whom we contacted, and they attempted a repair, but it did not work. We decided to replace it, and Castle Windows were our first choice. As previously, Carl gave good advice when he visited, and the installation team were first class also, everything was done to timetable, they were communicative, and left no mess. Again, we are pleased with the installation, and, while two years is insufficient for a long term opinion, we are not anticipating any problems, and expect the new window to be as trouble-free as the living room and bedroom windows have been.

Got quotes from national and local companies, Castle were the cheapest. Helpful salesmen, explained options and showed them on his laptop. Fitted 4 weeks after placing order, as agreed. Fitters arrived on time and began work immediately. Cleaned up as they went. Everything fitted first time and fitters clearly knew their job. Installation completed in 1.5 hours, area and windows cleaned. They explained operation of door and that they would fix any problems within the 10 year warranty period. Doors look great. Can't recommend this supplier highly enough.
