This company is dreadful, we have got a half built garden room which is still wrong in that the walls are too high to have a pitched roof and the window apperture is too high from the ground. He sent... See more

Excellent service throughout,excellent price,great team of helpful/skilled fitters! I love my new sliding sash windows and my home is so much warmer now.A big thanks to John and all involved
New window
I found sage after having a bad experience with another company. Sage gave me a no obligations quote that was almost a third the price than the other company had quoted. The window was installed to a high standard and completely changes the room. Would definitely recommend.
Great Quality Fitting & Doors
I had double french doors fitted and Sage Windows and Doors did a great job. It was done very quickly and they kept me in the loop every step of the way from quote to order to delivery and fitting. Fitted to a high quality standard.
Thanks!!
Christmas cheer

Highly Recommended
Having requested quotes from at least 5 x Window and Door Companies my wife and I decided to go with Sage Windows and Doors. We were both impressed with the pre-sale chat and found Sage Windows & Doors to be very competitive with their quote compared to other companies. The timelines given for installation were kept and we were both very happy with the finished product. The installation team were very professional causing little or no disruption and leaving each room in a clean state after installation.
Several months have now passed since the installation and we are still more than satisfied with the quality of the windows and doors, we would have no hesitation in recommending Sage Windows & Doors to anyone looking to replace their own windows or doors.
I would not buy from this company again
I would not buy from this company again. A one star review speaks for itself but I have been asked to add clarification.
Following the installation I reported a number of issues to the company. The two main ones being a) the patio door was on the wrong side and b) I was not happy with the plastic strips that had been used to hide the gaps between the installation and the wall. I eventually raised a formal complaint but despite extensive communication with the company these issues have not been resolved. The whole process has been painful. I have since had the the walls replastered to fill in the gaps and the company has told me that this has invalidated the guarantee. Not sure why.
I strongly suggest that with this, and any such company, that you write down the exact details of the installation regarding door / window sizes and location (what side the door is on) and exactly what you expect from the company in terms of installation and fitting. Get this signed as part of the contract and it will be legally binding. The simple document the company uses is insufficient in detail to provide legal protection. Buyer beware.

Brilliant quality windows installed by experts at a very competitive price. I was impressed with the sales representative who described the product and process succinctly. The windows transformed the house and the heating bill. Very pleased that I chose this company.

Contacted John at sage on the recommendation of my neighbour who was so pleased with the windows and doors.
John visited us on a Sunday morning and went through every detail regarding what we wanted.
We requested windows throughout, 3 doors, fascia and guttering.
Having contacted other companies and being staggered by their prices we were bowled over with the excellent quote.
A time was arranged for fitting and work started exactly as planned. We had lovely workmen here who were polite and courteous at all times. They kept the house as mess free as possible and cleaned up to a high standard every day.
The work was completed in an excellent fashion. We had one window that was cracked in fitting but this was replaced the very next day. Nothing was too much trouble for them and the standard of product and work completed was second to none.
We would highly recommend not only John who was a pleasure to deal with but the company as a whole. Their reasonable prices with no compromise on quality, the professionalism, and overall stress free experience.
We would certainly use them again.
Thank you for giving our house kerb appeal and most of all nice and cosy with these excellent products.
I would totally recommend Sage Windows…
I would totally recommend Sage Windows to anyone. All our windows were replaced last year. Their rep was lovely, most informative and helpful. Their price was extremely competitive and the fact that we were in a 3rd floor flat was not an issue - unlike other well-known competitors who would not quote for a property above a 2nd floor! The work was carried out in one day, was of top quality and perfectly fitted, with absolutely no mess and guaranteed. We'd give them 5/5!

I had all my windows replaced including two bay windows last year. In addition to this I had a new front door fitted. The service was excellent and can not fault it. They even fixed my patio door whilst carrying out the installation.
I have since recommended to several friends
