First class service from start to finish. The guys turned up on time, they put protective covering down, carried out the work swiftly and to a high standard. Cleaned up afterwards. We are delighted with our new door. I would recommend them to all my friends. Great products and a great service!

I cannot fault any aspect of Celsius Windows' service, from the initial visit right through to the expert fitting of my new replacement windows. I was particularly impressed by the competitive quote, customer service, punctuality, politeness and efficiency. I would not hesitate to recommend them to others.

Celsius replaced a double glazed window for us .John and the rest of the team were efficient and courteous . Their price was competitive and their service and product was first class. We had 3 visits from Celsius , first for an initial quote then the surveyor taking final measurements for manufacture and then the installation. They arrived when they said they would and did a very good job. Would definitely recommend.

Replacement patio doors.

Communication was great. They came when they said they would. Replaced patio doors as although we are in relatively new house we had problems with the locks and there was a gap at the top of one of the doors. Noticed a big improvement in the quality of the new doors. No more draughty or problems with the locks. Would highly recommend, quick to install and workmen cleared up after them.

I found Celsius Windows to be cost effective, efficient and extremely tidy. The team arrived on time and started and finished work on the specified schedule which had previously been discussed and agreed.
My many questions were all answered without making me feel it was an issue.
My new windows are very good and I am already feeling the position difference with hearing and sound. Thank you again John, Kenny and George.

From start to finish I was more than satisfied with the work done by Celsius Windows. Calls made to them were promptly dealt with, visits to the showroom were encouraged and questions/advice helpfully given. I was delighted with the installation of my new door and would not hesitate to use the company for future work and would thoroughly recommend them.

Review Comments
I recently had French doors replaced and some window re-sealing done by Celsius and was impressed from start to finish. The whole process - initial discussion, quotation, survey, installation and follow-up - was smooth and well organised. Everyone I dealt with was friendly, professional and respectful of our home, and any small issues (including a cracked slab outside) were put right quietly and without fuss. The price felt fair for the quality of the product and workmanship and it's clear they care about customer satisfaction and repeat business. I'd be happy to use them again and to recommend them to others.
