Testimonials for timber windows

"I would also like to add how pleased I've been with you and your team's professionalism from start to finish. It is always a pleasure to work with a company who do what they promise and when it was promised. Please pass my thanks to Paul for excellent design accuracy and supervision of installation and especially to Kevin and Michael, who were a pleasure to have around the house. They worked extremely hard, have done a first class job and were incredibly tidy workers, too. I am delighted with their work."
Andy H, Teesside
"I would like to confirm, how happy we are with the windows themselves, together with the excellent workmanship of the team...... manufacturing as well as installation. Mike, Kevin and Willie were outstanding (also for a couple of days Kevin and Michael). They completed the positive experience we have experienced whilst dealing with you and the team at Blackthorn Windows. I will never look at another window in quite the same light again!"
Mark and Helen
Near Beverley, North Humberside

"I just wanted to say how delighted we are with the windows and the way they were fitted. I was not looking forward to the job being done since I was worried about the state of the render on the outside and the dirt on the inside after completion. I can honestly say that the lads have done a superb job concealing the slight tilt in the previous windows and leaving the house and outside clean and tidy. They were easy to have around and were happy to provide extra help if asked. They appeared to take a pride in their work."

I have just had a curtain fitter come to the house, he said that he saw lots of windows and he commented how nice it was to see the beautiful windows so well fitted.

Should you need a recommendation for a customer in Leeds, we would be very happy to be contacted.

"Rachel & I are very pleased with the sash windows and front door, they have certainly finished off the front of the house beautifully. Please pass on our thanks to Kevin & Michael for the job they did fitting the windows with minimum impact to the existing shutters and panelling, outstanding job."
Mr & Mrs I, Blaydon
"I would like to thank you for making the experience of replacing our windows a good one. It is nice to know that companies still exist where customer service, pride in workmanship and quality of product are clearly of as much importance to the members of staff as they are to the customer."
Mrs Handy, N. Yorkshire

"I would like to take this opportunity to express our appreciation for the straightforward, efficient and professional manner in which you and your team have worked and especially for the way in which your fitters carried out the installation. They were courteous and considerate, doing their best to minimise and clear up any mess that such a job inevitably involves. Not only are the new windows a big improvement on the ones that were in our house before but their style is also very much in keeping with its character."

Testimonials for timber orangery

"I would just like to take this opportunity to thank you and your team for another outstanding project at Mole End. I must say, I am so pleased that Paul persuaded me to go with the windows you have installed. They look fantastic and this was down to his expertise (and patience!) that we got the right choice. I would also like to express my appreciation of Kevin and Michael’s first class workmanship. They are a credit to your company and by some way the best tradesmen we have ever had do work on our house. Please pass on my thanks to them."
Mr Hurst, returning customer
"I should like t take this opportunity to say that we are delighted with the doors and to thank you for your excellent service. My wife and I found the window fitters to be extremely thorough and efficient and they made a great job of the installation."
Mr & Mrs Whitesmith, Co. Durham
"Can I also add that the level of workmanship shown by Alan and Michael was excellent? They showed an exceptional degree of care and pride in the work they carried out and we are more than satisfied with the results. As you know we have plans to re-glaze the front bay window in the Spring and will have no hesitation in asking you to quote for the work. And should you wish us to comment on the high level of workmanship to other future customers we would be more than happy to do so."
Mr & Mrs Coles, York
"A quick note to say that our new doors - and window - are installed and we could not be more delighted. We can't walk past the doors without trying the handles or the marvellous blinds or just standing and looking at them. I guess the novelty is bound to wear off eventually, but the products themselves are clearly built to last. The sheer quality of the doors and window is unmistakeable, and I have to say is matched by the quality of the installation; Michael's and Alan's work was impeccable in its attention to detail and they remained indefatigably cheerful in spite of the miserable weather they had to cope with outside. They're brilliant!"
Mr & Mrs McConway, Newcastle upon Tyne
"Following completion of your work on Friday, I just wanted to write and thank you for a job extremely well done! Your assessment of the project and organisation of the supply and fitting were very good and mention should be made of Paul Coates’ accuracy and precision with regard to design and planning. Also, the painstaking effort undertaken by Kevin and Michael who were extremely accommodating is particularly worthy of note! The standard and level of workmanship produced was second to none and it was a great pleasure to have them around! Overall, I cannot recommend you and your team highly enough and they are a tremendous credit to Blackthorn Timber."
