COMMERCIAL WINDOW CLEANING

Bringing clarity and curb appeal to your property with professional corporate window cleaning.

Window Cleaning For Businesses

Commercial window cleaning keeps your premises looking professional while protecting your building’s materials over time. Clean windows allow more natural light in, create a better working environment, and leave a positive impression on staff, visitors, and clients. When left untreated, dirt and grime can lead to staining, reduce visibility, and even contribute to long-term damage.

At Neptune Cleaning, we provide commercial window cleaning for a wide range of sectors, including offices, schools, retail, hospitality, and industrial sites. From one-off cleans to regular contracts, our experienced team delivers consistent, high-quality results, even on buildings with complex access needs.

We’re also experienced in working with businesses through formal tender processes and can provide supporting documentation and mobilisation as needed. For those seeking a complete solution, we offer additional exterior cleaning services to help streamline building maintenance under one reliable provider.

When you book regular commercial exterior cleaning with Neptune, you gain the benefit of always knowing that your premises remains spotless year-round. Attract new clients and impress existing ones! As the exterior façade is the first thing people see when they interact with your business, it’s important to keep it in top condition. Regular cleaning also stops the spread of moss and algae, which can damage a building over time. You will appreciate your building more when it has no streaks or marks, brightening the environment you come to work in!

Depending on the type of business you run and where it is situated, your business exterior may need bi-weekly or monthly cleaning. In different seasons, building exteriors have different needs as well: in Winter, there is a higher level of rain which can create streaks and scatter debris. In Summer, sun can bleach building façades and fade paint. If you’re concerned about how your building will fare over the year, talk to us today!

As our cleaning concerns your business’ exterior, you don’t need to be there to let us into the interior. We can perform our cleaning duties outside of your normal working hours. If your building is enclosed and needs gate access, we can liaise with you about how to enter the exterior property without you needing to physically be there.

One of the secrets of this system is the final rinse. This removes any pollutants which may have been dislodged from the tiny gaps between the window frame and sealed units. The final stage of the filtration takes place as we pump the pure deionised water from holding tanks in our van through resin filters into the hoses which feed our cleaning poles, ensuring that this water is as pure as it practically can be. The water droplets left on the window will be 100% pure and will dry completely clear. Using a cloth or squeegee to dry windows would only result in contaminating the clean surfaces with smears and blemishes. We offer a 100% satisfaction guarantee and have a high retention rate of customers. Neptune Window Cleaning will give you the cleanest windows and frames you have ever had.

Unlike traditional window cleaning, there are no soapy residues left on your windows after they have been cleaned to be dissolved by the pure rainwater and cause spotting or streaking. Rainwater is nearly as pure as our 5 stage filtered, deionised pure water, and will also dry perfectly clear without spotting. This means we work all year round apart from in the most extreme of weathers when it would be unsafe to work.

This means you get unrivalled reliability and service, and windows and frames which are always clean.
