Commercial exterior cleaning in Belfast and Lisburn


The first impression of a business gets made in the car park, not the reception. We clean the outside of commercial buildings across Belfast, Lisburn and the wider area. That includes car parks and yards, cladding and walls, gutters, shop fronts and windows. We can do a single clean, or come on a schedule so the site never looks neglected.
Car parks, yards and hard standing
Bay markings disappear under algae, oil stains spread from the same three spaces, and moss creeps out from the kerb line until a car park looks like nobody is minding the place. We rotary-clean the surface, degrease the oil patches, and take the arisings with us rather than leaving a tide line across your entrance. Loading bays, service yards, warehouse aprons, bin stores, walkways and fire escapes all go in the same visit.
Cladding and building elevations
Profiled steel, composite panels, painted cladding and render all clean up well, but not with a pressure lance. High pressure drives water behind the panel joints and lifts coatings. We soft wash elevations with the correct solution at low pressure and rinse down, which takes off the algae streaking and traffic film without touching the finish or the seals. Most single-storey units and two to three storey buildings are done from the ground with no access equipment.
Gutters on larger buildings
Blocked commercial guttering is what turns into a water ingress claim. We vacuum gutters up to 70 feet from the ground with a camera on the pole, so you can see what came out and what condition your gutters are really in. There's more detail on our commercial gutter clearing page.
Shop and office frontages
We clean the glass, frames, signs and entrance area early in the day or on a set day, so we don't get in the way of your trade. Regular cleans are invoiced monthly rather than paid on the day. See commercial window cleaning for more.
Maintenance schedules, not rescue jobs
Most sites work out better on a schedule: car park quarterly, cladding once a year, gutters once or twice depending on the trees around you. It costs less per visit than letting a site go and paying for a recovery clean, and the place never has a bad month. Tell us what you have and we will put a sensible frequency and a fixed price against each part of it.
Working on your site
Method statement and risk assessment before we start, public liability cover to £1,000,000, and out-of-hours or weekend working where access and noise make that the sensible option. Commercial accounts are invoiced monthly.
Who we work for
We work for factory and warehouse units, shops, pubs and restaurants, offices, schools and colleges, and letting or managing agents with several sites to look after. A recent example is Hazelwood College in Newtownabbey. We cleared the gutters on every roof on the site from a cherry picker, because the shape of the roofs meant our poles couldn't reach.
Send the site address and a couple of photos, or ask us to walk the site with you. Surfaces and elevations are covered in more detail under pressure washing and soft washing.
On site
Commercial work, photographed on the day
Here's our work on cladding, yards, shop fronts, churches and warehouse roofs, for Tesco, storage units, industrial sites and retail parks. It's the same equipment we bring to a house, scaled up for a business site. High work goes up in a cherry picker.

Hazelwood College: gutters cleared from a cherry picker
Every roof on this Newtownabbey school needed its gutters cleared. The gutters were long and packed with moss, and in places grass and weeds had taken root in the silt. We worked from a cherry picker instead of walking on the roofs, so nothing fragile was stood on and the car park stayed open around us.
