Commercial Window Cleaning in South Wales
Dirty windows say something about a business before anyone walks through the door. A layer of grime on the glass, water marks from months of rain, a film of dust on the frames. Visitors notice. Staff notice. Clients notice. And the longer it sits, the harder it is to shift.
MÔR Cleaning provides professional commercial window cleaning across South Wales. Internal and external glass, frames and sills, partitions and entrance glazing, all cleaned using purified water systems and modern reach and wash technology for a streak-free finish, safely delivered, with minimal disruption to your working day.
What our window cleaning service covers
We clean the full window, not only the glass. Our commercial window cleaning service includes everything the building needs to look its best from the outside in.
That typically covers external glass cleaning, internal glass and partition cleaning, window frames and sills, removal of dirt, dust, fingerprints, water marks, and environmental build-up, glass entrance doors and internal glazing, and cleaning of glass partitions and meeting room screens. We work across offices, business parks, schools and educational facilities, healthcare environments, retail premises, industrial & manufacturing units, hospitality venues, and communal areas of commercial buildings.
External Glass Cleaning
We clean external windows using purified water systems and reach and wash technology for a streak-free finish without the need for chemicals.
Internal Glass and Partitions
Internal glass, meeting room partitions, entrance doors, and glass screens are cleaned by hand with professional-grade squeegees for a thorough finish.
Window Frames and Sills
Frames and sills are cleaned as part of a full window cleaning programme to ensure the whole window looks right, not only the glass.
Removal of Environmental Build-up
We remove dirt, dust, fingerprints, water marks, and environmental contaminants that can cause lasting damage to frames and glazing if left unchecked.

How we clean
Purified water systems
Our primary method uses deionised, filtered water fed through a pole system. The water does the work. Because the impurities have been stripped out, the glass dries naturally without leaving residue, streaks, or spotting. No chemicals needed for the external glass, and no smears left behind.
Reach and wash technology
Water-fed pole systems allow us to clean higher-level windows safely from ground level. That means fewer access platforms, less disruption on site, and no one working at height when there is no need to be. For most commercial buildings, reach and wash covers everything up to several storeys without specialist access equipment.
Traditional cleaning where it suits
Some internal glass, low-level glazing, and detailed partition work calls for hand-cleaning with professional-grade squeegees and applicators. We use the right method for the right surface, and we pick that based on the building, not a fixed process.
Safety and compliance
Every job is covered by a site-specific risk assessment and safe working practices. We are fully insured, and our teams follow health and safety compliant procedures on every visit. You get clean windows without any of the liability concerns that come with poorly managed access.
Scheduled or one-off cleaning
Some buildings need monthly cleans. Others work better on a bi-monthly or quarterly cycle. It depends on the site, how exposed the glass is to traffic, weather, and pollution, and how much natural light matters to the people inside. We set a schedule that fits your building and your budget, and we stick to it.
If you need a one-off clean before an event, a new tenancy, or an inspection, we do that too. Same standards, same equipment, no ongoing commitment required.
Why clean windows matter more than people think
Natural light improves how a building feels to work in. Dirty glass blocks more of it than most people realise. A properly cleaned window lets more daylight through, which makes the space brighter, the atmosphere better, and the energy bill a little lighter.
Then there is the appearance. A clean building front tells visitors and clients that you pay attention to detail. A neglected one tells them the opposite. The glass is often the largest visible surface on a commercial property, and it is the first thing people see.
Regular cleaning also protects the glass itself. Environmental contaminants, hard water deposits, and pollution build up over time and can cause lasting damage to frames and glazing if left unchecked. Cleaning on a proper schedule prevents that and extends the life of the windows.
Flexible scheduling, minimal disruption
Window cleaning can typically be completed during business hours with little disruption. For sites where that is not practical, we schedule visits early, late, or at weekends to suit the way your building operates. Either way, we work around you.
Eco-friendly where it counts
Our purified water systems clean effectively without chemicals on external glass. Where cleaning solutions are needed for internal surfaces, we use eco-friendly products that are safer for occupied buildings and better for the environment. That approach sits at the heart of how we work across every service we offer.
Part of a wider service
Window cleaning often sits alongside our other building services. We also handle commercial cleaning, washroom services, carpet and hard floor maintenance, janitorial supply, and pest control. One team, one point of contact, and one provider who already knows your site. That makes scheduling easier and keeps standards consistent across the whole building.
Accountability built in
We audit our own work. Every visit is tracked, and our GPS-enabled clock-in and clock-out system verifies attendance. If something is not right, we want to know about it before you do, and we act on it. That is the same accountability we apply across every MÔR service, and it is why our clients trust us to keep coming back.
