Fantastic service throughout the whole process. The fitter arrived and was aware we were a shielding household during covid. All necessary precautions were taken to keep us safe. The new front door looks amazing, fitter was polite and careful, no redecoration required and no mess .We will definitely recommend you to friends and family.
The gents who came to fit our new doors were absolutely amazing. They both worked very hard and efficiently. They worked well as a team and brought a positive attitude with them. Our doors look absolutely amazing. I’m recommending Spire Glass to everyone!
The fitter was meticulous, friendly and considerate, and his attention to detail was really impressive - it's very seldom that I'm this happy with work carried out for us!
When I got home from work today to see the finished job I was gobsmacked to say the least. The finish of the door is superb, the installation is completely snag free, and both the admin staff and the fitter have been amazing throughout. The whole process from the initial contact through to the complete job has been totally easy and stress free. I would 100% recommend Spire Glass to anyone and everyone!
Really pleased with the team that fitted the windows and the support I got from Spire Glass throughout the issues I had with the management company within my block of flats. Loving my new windows and the saving on the electric bill! Thank you
I had been putting off getting my windows repaired or replaced due to the cost and potential mess. I have a lot of windows but was surprised by the quoted cost and went for a phased replacement of all windows. I was very pleased at the outset with the level of finish and lack of any redecoration necessary. So pleased that I amended the order to replace one large window with a set of Bi Fold doors! Very pleased, I'll be back next year.
Spire Glass' installers did an excellent job. They were quiet, respectful, tidy and efficient. We are delighted and have already recommended Spire Glass.
Not only was the price great but the service has been fabulous from start to finish. All work was completed with complete perfection and thoroughness which was a delight
My son and I are delighted, no more draughts and condensation! The superb quality and high standard of fitting – second to none. It was a true pleasure to have you here. We will not hesitate to recommend Spire Glass to any likely customers seeking replacement windows, as we consider, without doubt, that you are the best!
Thank you so much for doing such a splendid job and in such an efficient manner. The windows have been much admired by people.
We are very pleased with the standard of workmanship and quality of the windows and doors you supplied.
...may I say thank you for an excellent job. From your friendly help at the estimate stage, through to fitting...... together with the excellent fitting and very neat work... it has been a pleasure to deal with your company. I will certainly be pleased to recommend Spire Glass to anyone who asks for an opinion
Thank you for making a first class job of my windows. The workman was pleasant, hard-working, clean and tidy
Two gentlemen fitted a very large mirror and measured for my secondary glazing. I would like to express how delighted we were with their professionalism. First class service which is difficult to find these days.
I can’t believe how easy this has been ! The glass is exactly what we wanted and it looks perfect. Result, one happy wife ! Thanks again for your help with this, first class service.
Just had a composite door and 2 side lights fitted by Spire Glass Ltd. It was a first class experience from start to finish with special thanks to the fitters Neil and Tom who did a very professional job. We look forward to getting other windows done in the future
