I have written a little note with my payment – Your team were just excellent – Oliver, Denzel and Ryan. I have recommended you to my neighbours, and will continue to do so. They were timely, they were keen, nice everything A star!! – I can’t believe I didn’t know you before, I’ve lived here for thirty years and never had such good window cleaners. With pleasure, put my comments on your Website, 100% – Pass them on to the team and your management, I really mean it! Also, the way you answered the phone at the booking, so kindly, not loads of questions, just perfect.

M.J. – South Kensington – 4th July 2024

Rob – Hampstead NW3 – 20th May 2024

It was all ok thank you. Your guys were very professional, kind and polite. I will definitely be using you again, I don’t know why I should use any other company.

Ellie – Euston – NW1 – 20th May 2024

I’m keen to give a hearty two thumbs up to Bradley and Ellis, who were excellent in every way. I hope you will be able to send them every time! They were entirely expert and took every care, inside and out. It was refreshing to have experienced such professional work, and there hasn’t been this much light in the house for many years, if not ever! I hope you will pass my thoughts onto senior management: credit where it is due! – I wouldn’t go anyplace else, you guys are first rate!

Phillip – Twickenham – TW1 – 13th May 2024

It was fine, they did a good job between them, told me what they were doing, if I was happy, asked if anything else was needed. They were careful, and responsible, and very nice. I will call upon you again.

We were happy, The glass box is a difficult job and Bradley did it very well! Looked for you on Google, but was looking for a more specialised company, who do commercial and residential properties, to deal with the box! We’d like the same guy back again next time.

Steve – Muswell Hill – N10 – 15th April 2024

Absolutely Brilliant !! – Carlos and Ashley – they were wonderful, kind, respectful, delightful and on time! Really, really happy. They certainly knew what they were doing, like Spider Monkeys, so confident, efficient and quick! It was beautifully done and they wiped all surfaces. Out of all the companies I phoned, you were the first to get back to me. Very impressed with the staff, it has made a big difference! I have given your number to my neighbour and will give it to my friends. I will call you in about 4 months. I am certainly going to be talking about you!!

Victoire – Chelsea – SW10 – April 2021

The whole experience was absolutely wonderful from start to finish. Rayan was fantastic, the clean was brilliant. Impressed that he took shoes off without being asked, he was careful and polite. Told my friends about you already! I could not have asked for anything better 20/10 !!!

Judy – Twickenham – TW1

I had a visit from one of the cleaners this morning and originally asked for a quote. But Ben who I opened the door to said he could clean my conservatory glass roof now. So why not I thought. He has done a most fantastic job and nothing was a problem to him. So thank you N.Clark for your most professional and reasonably priced service. So until the next time.

Anthony – Chiswick – W4

Very very happy indeed !! Blown away by level of service and courtesy from office staff – superb and an asset to the company The website impressed me and the detailed cleaning video gave me confidence to use you.The team who cleaned were polite, presentable gentleman, engaging and chatty. An amazing job was done!!!! So glad I found you and will definitely be using you going forward – Probably the best window cleaning service in Putney or London!!

Marco – Putney – SW15

Hi Nicholas, I would like to thank you for your help at such short notice. The guys did an excellent job and we are really happy with the level of service they provided. We would highly recommend you. Kind Regards

Very happy indeed, would like the SAME TEAM next time. They were very well presented, very professional. They were also very discreet, checking on each level before entering a room. The job was first class, the windows have never been so clean! Very good ambassadors for your company. I would recommend you to anyone looking for a window cleaner

It was absolutely wonderful, I am incredibly pleased. Fantastic guys who did a really good job – I will recommend you to my family and all my friends. I have been looking for a cleaner desperately. Someone who could clean ALL my windows, because some of them are very tricky. Having such pleasant people made all the difference, and that is so important to me – Thank you
