Gutter Cleaning in Windsor
When you hire guttering cleaning professionals, just like us, you’re not leaving the health of your property to chance. Just like anything that works systematically, your guttering system needs to be well-looked after and optimised to do the best possible job. Abacus have the industry-leading equipment, expertise and tools to ensure your water-flow is working just like it should be. We’ll also do a site-survey to check if there’s any potentially damaging signs of water leaks.
To make sure your guttering system is working effectively throughout the year, we recommend you getting it checked at least once or twice a year. This is to ensure no blockages are happening or about to happen and we can step in before things get worse.

UPVC Fascia, Soffit & Cladding Cleaning in Windsor
Cladding cleaning at domestic properties is a time-consuming process. As well as cladding cleaning, we can also thoroughly clean your UPVC fascias and soffit boarding. By keeping on top of this type of cleaning, you’re significantly reducing the chances of repair or replacements which could be very costly.
What is UPVC?
UPVC is soft white plastic, with a coating on the outside. If dirt is left on UPVC for a long time, it can destroy the coating and damage your installation.
There are benefits to having your UPVC Fascia, soffit boarding, and wall cladding cleaned. They are listed below:
- No need for expensive scaffolding.
- No need for hydraulic lifts.
- Immediately brighten the appearance of your property.
- No need to risk anyone’s life.
- No need for replacement.
Roof Lantern, Rooflights & Dome Cleaning in Windsor
Roof lanterns are the ideal installation if you’re aiming to bring more light in your property and be more environmentally friendly. When left too long and neglected without maintenance, lichen and moss can start to build up and damage the appearance and health of your roof lanterns or domes.
Our non-aggressive service removes these unwanted and unsightly materials to reveal its original state. If you would like your tile or slate roof cleaned, call Abacus – your expert window cleaners in Windsor – to arrange your free no-obligation quote.


Commercial Cladding Cleaning in Windsor
Having solid cladding on a commercial building is essential to prevent damage from weathering.

If you’re trying to attract or seal more business, the long-lasting impression of your outside exterior may be more important than you first anticipated. Offering tailored commercial cladding cleaning services for different types of commercial properties, we can get your cladding looking as good as new by the time we’re finished!

Abacus Window Cleaning have been doing my windows for the last few months and after issues with previous window cleaners not turning up I can highly recommend Abacus. They are a professional and reliable company and always let me know when to expect them. My windows are always left looking so clean once they’ve been. Thank you guys.

Just had my first clean and I was extremely impressed. The guy who came to clean was super quick and efficient, no messing just came and did the job as promised. Payment was done online and I received a text the day before they came so I was not disturbed and literally had to do nothing.
