What a throughly super nice guy Konstantin is. He did a fantastic job of my very dirty post renovation windows. The windows were covered in brick dust, plaster dust and paint splashes. He arrived on time, and then worked for 9 hours solid. They look amazing! Cant recommend enough, will use him again. Thank you Konstantin.

Excellent job. Konstantin arrive right on time and did a very thorough clean of my windows. He also cleaned the surrounding paintwork, frames and sills, which I wasn't expecting. Windows are really bright and clear now. Friendly and professional, highly recommended.

Great work and great communication from Konstantin. Highly recommended

Konstantin and his son did amazing job cleaning my windows. I was really impressed with his thorough and almost scientific approach. He brought his own filtered soft water! So it doesn’t leave any streaks! The difference in the before and after is really massive. On the top of being really good at cleaning Konstantin is also very professional, polite and good at communication. I would not hesitate recommending him and would definitely call on him to clean my windows again!

Very happy with the service. Great people and would use again. Thoroughly recommend.

Konstantin came in last minute and did an absolute brilliant job on my windows. Even though some of them was tricky to reach he was persistent and left a spotless result. Would absolutely recommend!

Very professional deep window cleaning. Recommend them to everyone looking for a professional window cleaning service.

Konstantin arrived exactly on time and was courteous, professional and careful throughout his time in our property. The quality of his work was exemplary, I would go so far to say that he is the best window cleaner I have ever used. Despite the difficult access to all our windows he managed to leave them crystal clear from corner to corner and inside and out. I strongly recommend Konstantin and Key4U Ltd and shall have him back to clean our windows regularly.

The best deep cleaning I’ve ever had. The company is responsible and trustworthy. Recommend 👍

We had Konstantin come out to clean our windows, and we couldn’t be happier with the results! He was professional, quick, and the quality of his work was exceptional. Our windows have never looked this clean before - it’s like we’re seeing everything in HD! The pricing was very reasonable for the high standard of work provided. Highly recommend Konstantin and his company for anyone looking for top-notch window cleaning!

The rep was most helpful in moving furniture back after cleaning at what was a very reasonable price.

Recommended: Best Window Cleaner Just cleaned all our windows with this amazing person who I found cleaning a shop window and feel I should share his details as he did so many windows and wasn't clock watching but wanted to actually get the windows in top condition after all the winter rain and limescale on them.

Without doubt you have given this house the best and cleanest windows in the street and probably in its entire life!
