Window Cleaning References:

“I must say that was the most professional window cleaning I’ve ever experienced. Well worth the wait. Big thumbs up to your guys – I shall definitely be using N Clark again.”
Daniel – Islington – N1 – July 2017

“My windows were cleaned by Ryan and Tash. They were very punctual, very honest, extremely professional. I didn’t speak to Tash at all but I must say Ryan was exceptionally polite, well-mannered and friendly. He assessed my windows quickly and understood what I wanted and worked well within the confines of the budget that I had. They were neat and time efficient. The windows were cleaned well. I will not hesitate to recommend them. I would also like to add that Cleo, the lady I spoke to on the phone also had an exceptionally nice phone manner, which is quite rare these days. As a whole I have had a really good experience with your company.”
Rebecca – Kensington – W14 – July 2017

“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”
Mandana – Chiswick – W4

“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.”
Steven – Notting Hill – W11

“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.”
