Water Fed Pole

How We Work

We use modern window cleaning equipment, utilising water fed poles and pure water cleaning technology. This is proven to be the most effective way of cleaning windows, and ensures the highest standards of service for our customers. As we aim to offer the most comprehensive window cleaning service in Gwynedd and Anglesey, we also clean interior windows by hand using more traditional methods.

Gutter Cleaning

Gutter Cleaning

We have many years of experience when it comes to cleaning all kinds of gutters. We have access to industry-leading technology which allows us to quickly clean guttering in all kinds of properties. Thanks to our equipment, we can often clean guttering from ground-level, which eliminates the need for ladders and scaffolding. As a result, the cleaning project is much safer and can be carried out extremely quickly.
