Customer Service
Recently had JC Windows fit a new conservatory roof and double glazing throughout. John and his fitters Martin and Mark did an excellent job during 2 of the wettest and coldest weeks of the year. Everything from first contact with Mark the sales adviser through to fitting has been of the highest standard. Couldn’t recommend them enough.

Excellent work replacing 4 windows
Customer Service
We were quoted a very reasonable price, following a visit for inspection and advice. This stage was very informative and enabled us to discuss and design the windows to meet our needs. The fitting was completed efficiently and we are delighted with the final outcome. In the difficult times the workmen took care to socially distance All the company employees we dealt with were friendly, polite and knowledgeable Can certainly recommend

We have just had bi-fold doors fitted and are very happy with the results. The work carried out by the builders and fitters was clean and efficient. All work is done to a high standard by a friendly and professional workforce. Everything was completed on time to a very high quality. Good value for money. Will happily use JC Windows again.

On moving to a property we discovered that the roof in the conservatory due to its age was leaking. I used JC Windows as recommended by Which Magazine. From the initial estimate to the completion of the job it was carried out by what I can only say was in a total professional manner. I am very happy with the result and would not hesitate in recommending this company.

Great work on schedule
Customer Service
A replacement bay window to ground floor and two first floor bedroom windows to the front of the property were installed. The representative who arranged to call round to provide an estimate was helpful and polite and the surveyor who called to measure up was pleasant and efficient. Dates for appointments were pre arranged and on time. I was given two months notice of an installation date. The work was completed on time and the installers were respectful and kept any disruption to a minimum. Extremely happy with the standard of work.

New Windows
Customer Service
We have just had new conservatory windows fitted by JC Windows. We are very pleased with the work carried out on our property. The windows were fitted by two very polite fitters and the conservatory was left clean and tidy on completion. I would fully recommend this company for value and workmanship.

Lovely job - upgraded conservatory
Customer Service
JC Windows did an excellent job totally upgrading our 1990s conservatory - new frames, doors, windows and new roof. They were very polite & tidy and removed all the rubbish. I would recommend them on value for money, quality of work and excellent customer service.
