Abacus Window Cleaning Ltd

We’re so pleased we found Abacus. They clean the outside windows at our home in Ascot, and every time they visit the house feels instantly brighter. There’s something lovely about looking out through properly clean, sparkling glass — especially on a sunny day — and they never disappoint. They’re always reliable, friendly and professional, and it’s clear they take real pride in their work. Even in unpredictable weather, the standard is consistently excellent. It’s such a comfort to have someone dependable who quietly does a wonderful job every time. We wouldn’t hesitate to recommend Abacus.

Our windows and doors were cleaned by them for the first time today. The entire job took only two to three minutes, which I confirmed on my outdoor cameras. I can assure you that, despite all the promises they make – whether customer satisfaction, spotless glass, or cleaned frames, sills, doors and windows – they do not deliver, not one of them. It is remarkable how consistently disappointing they are. All they did was splash some water. They certainly did not clean the sills or anything else, and in fact our windows were noticeably cleaner before their visit. Now they are covered with spots and streaks, despite their so-called guarantee. They are refusing to issue a refund because I will not allow them to “rectify” the work. That is hardly surprising, as they are clearly incapable of cleaning properly, and I will not give them the chance to make things worse, as they have already done for many other people according to their Google reviews.

Had my windows cleaned today 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.

Had our first window clean today by Abacus. Very pleased with the service today. Just wanted to also highlight Calum, who did the clean today. He was friendly, professional and did a great job. Thank you Calum! Also just wanted to mention I spoke with Luke when I signed up to the service who was equally friendly and professional. Really impressed so far! Cheers!

The whole service was brilliant from start to finish! Easy to book and easy to pay. Windows left sparkling. I look forward to having them cleaned again in another 6 weeks.

We got recommended to used Abacus to clean our windows, frames, and seal, and can say we have 0 complaints throughout the last few months! Additionally Cobi and Hayden seem to be great characters, always friendly, smiling and giving unmatched customer service

Abacus have been cleaning my windows for the last few years. I have always been happy with the quality of the cleans and the professionalism of the team. I recently had my driveway cleaned with them for the first time and I am extremely happy with the result. I would highly recommend Abacus for window cleaning and now driveway cleaning too! Excellent work.

I basically signed up for a £30 month subscription just for someone to spray water on my windows and clear off. When I had a cold call at my door to sign up for this service I was informed the windows and sills, plus the fascia’s would get cleansed, but no such luck. The first clean was complete waste of my money, guy came round sprayed waters at windows, leaving streaks and the sills and fascia’s remained dirty. I immediately cancelled after the service. I could have done what he did myself with the jet wash!

Kieran came out to clean my windows today, he was so friendly and professional. He done such a great a job, you can really tell he takes pride in his work. I will be recommending him to my friends and neighbours

We've been having our windows cleaned by abacus for around a year now. It's great to receive the texts ahead of time to remind me of their visits, payment system is really easy and I'm always impressed with the job they do. Very discreet and easy to work with.
