About Us

Please see below some of the many testimonials that we have received from our domestic customers. We are also happy to supply on request copies of customer testimonials letters from business, charities and organisations.

Sister Cunningham - Our lady of Holy Souls Church - North Kensington

I wish to highly recommend Sash Window London, for there excellent work. Thers prompt attendance on an emergency job call out was wonderful and much appreciated. Sash Window London had to repair a sash, which, because of its age, was almost beyond repair but his patience and skill soon had it looking new. I found John to be extremely courteous and polite and I have no hesitation in fully recommending him and his company.

Sister Mathews - Sisters of Charity - Victoria

May I say how delighted we are with your work and for the meticulous way you and your team carried it out. We also appreciated the care you took to clean up at the end of the hard working day.

Mr Portnoy - St Johns Wood

I would like anyone to know who is considering using this company for the refurbishment of their windows to know how pleased I was with their work. The quote was very competitive. One of the reasons for choosing them is that the owner of the company also does the work. Mr Sisk and his co-workers arrived early on the day and worked until the job was completed. One of the aspects of their works I was impressed with was their cleanliness. They covered the floor and furniture in the room with dust sheets and even the areas outside the room. Their workmanship was to a very high standard and I had no fault with the results. You could not choose a better company for this type of work.

Mr Brake - Kilburn

Both Claire and I are extremely grateful for the work you carried out on our sash windows. We were most impressed by your prompt and efficient service. Sadly in this modern age it is not always easy to locate people such as yourself particularly in the vast expanse of a large city such as London. Once again thank you and we certainly know who to call should any other windows break down in the future.

Mr Rhatigan - Queens Park

I write as a very satisfied customer. I recently had five Victorian sash windows removed and completely overhauled. The standard of work carried out on the windows by John and his colleagues was excellent. I have no hesitation in recommending this company to anyone.

Mr Hazeldean - Camden Town

We are so happy with our new double glazed sashes, the work John and his team done on them has truly exceeded our expectations. John has been a great find, your staff our all so professional and friendly and surprising brilliant at cleaning behind them, the house was left spotless. I have no hesitation in recommending your company to anyone I know.

Mr Petricevich - South Hampstead

I just wanted to write a quick note to let you know how appreciative we were of your prompt and excellent service. We had struggled to find someone with your skills. The replacement window and counter-weight adjustment are splendid and work perfectly - I have not hesitation in recommending your work to any of my colleagues and friends.
