I had my windows cleaned today by Abacus Window Cleaning. A polite young man called George carried out the cleaning very efficiently and he did a very meticulous job.
Will definitely be using this service again.

Had my windows cleaned for the first time by Sid at Abacus and he did a fantastic job! His work was to a very high standard, he was polite, friendly and helpful and he came across as genuinely wanting to do a good job. The Velux windows had not been cleaned for a while, but his attention to detail to get rid of the stubborn moss was exceptional. I am very impressed with the care and consideration that went into his work and he made a brilliant first impression. Thank you Sid and thank you Team Abacus

Had my conservatory cleaned by Abacus Window Cleaning - highly recommend so sparkly.

Abacus Window Cleaning clean our windows and gutters at work and the service and results are excellent. Highly recommend Abacus.

Used this company for the first time and the windows were not cleaned properly, some were missed completely. Then they broke our roller shutter door, as they knocked something over, left it and then told me I could shut it. I did this and heard a noise and so ran to stop the shutter and removed what was stopping it from shutting. We had this on camera and they would not accept responsibility and tried to blame me, even though it was obvious this was not the case. We didnt have to pay for the windows but now we are being ignored and have had to pay to fix damage caused by their carelessness to our roller shutter door. Will not use again.

Ollie is always courteous and does a great job cleaning our windows. I will be extending the service soon to get our gutters cleared.

My gutters and windows were cleaned by Kieran today for the first time in 5/6 years. They have been completely transformed and look amazing. Thank you.

Had my windows cleaned inside and outside plus a gutters clearance. Perfect job carried out by Jayden. He explained exactly what he was going to do before hand and roughly how long it would take. A lovely young lad and very respectful. Would recommend asking for him.

Been using for years.
Always very professional and do a great job

We had a successful trial clean, but didn't want the frequency of future visits insisted on.
At short notice the company said they were coming the following morning, I didn't see that message or I would have cancelled - but they came anyway and did the front of the house but couldn't access the back.
They then sent a bill for £40 for work we had NOT authorised and have been hassling us regularly to pay and now (19/08/25) are threatening legal action if we don't capitulate - not a welcome prospect for people in their 80's....

I had Ollie clean my windows for the first time today and was very impressed with this conscientious young man. He was polite and courteous and carried at a tremendous clean of my property.
I have to say that I was dubious about using the water fed pole system as I just didn't see how purified water was going to leave my windows, frames and sills clean, however I can now state that my doubts were unfounded and this system has produced wonderful results.
Will definitely be sticking with Abacus Windows.

Amazing service by Olli. Brilliant Clean and a lovely young man.

Great window clean by Harry!

I have been a customer of Abacus for the last 3 years here in Ascot. On several occasions they have purported to have cleaned my windows and reminded me to pay but have not been anywhere near the property. The last visit on 20th November they completely neglected to clean one of our main velux windows (they have always cleaned it in the past) so I sent them a picture of it and asked if it could be done and/or a solution found to cleaning it (if their equipment no longer reached) to which I still have had no reply. They msg me today to say the cost of cleaning my windows was going up too…no thanks! Bye!
