Exterior Maintenance Services for Commercial Properties

Expert Exterior Maintenance for Businesses

When the outside of your building starts looking tired, grimy, or streaked with moss, it’s more than just a cosmetic problem; it’s a message. And not a good one. Our exterior maintenance services are designed to make sure your property speaks volumes, for the right reasons. At NZ Facilities, we help businesses across Auckland and Wellington keep their buildings clean, safe and looking sharp, no matter the weather or foot traffic.

Whether you manage a retail outlet, corporate office or industrial facility, we provide fully managed, professional-grade commercial exterior cleaning that protects your assets and enhances your presentation.

The Importance of Commercial Property Maintenance

Beyond aesthetics, regular, professional exterior maintenance plays a direct role in the performance, safety and reputation of your commercial property. Whether you manage a retail space, office building or industrial site, neglect on the outside can cost you, visibly and invisibly.

Here’s what a smart exterior maintenance plan actually gives you:

Moss, grime, pollution and UV damage don’t just affect appearance; they degrade materials over time. Regular building washing, roof treatments and pressure cleaning help prevent premature deterioration of paint, cladding, concrete, metalwork and roofing systems.

A clogged gutter today can become water damage tomorrow. Mould on the roof now can lead to internal leaks next season. By addressing issues early through routine maintenance, you avoid costly repairs and emergency callouts down the line.

Slippery walkways, hidden mould, blocked drainage, all can present risks to staff, tenants or the public. Regular pressure washing, gutter clearing, and roof cleaning help maintain a safer environment and support your compliance with health and safety standards.

Customers notice when a building looks clean, cared for and professional. The opposite is also true. Clean windows, tidy exteriors and grime-free signage show that your business takes pride in its space; and by extension, in its services.

No one wants to work or live in a place that looks and feels neglected. Keeping your building’s exterior in top shape creates a more pleasant environment for everyone on-site, from clients and staff to tenants and visitors.

Organic buildup in gutters and on roofs can attract birds, rodents and insects. By removing nesting and feeding grounds, exterior maintenance helps reduce pest intrusion, especially in hard-to-reach places where infestations typically begin.

Our Exterior Maintenance Services

We take care of the outside, so you can focus on what’s happening inside. Whether your building needs a fresh face, your roof’s looking worse for wear, or the gutters are hosting a wildlife convention, our team is equipped to keep everything clean, compliant and well looked after.

Window Cleaning

There’s something instantly sharper about a building with clean glass. Our commercial window cleaning service gives your property that fresh, polished look using a water-fed system and purified water technology. It allows us to clean windows up to several storeys high safely from the ground, with no streaks, no chemicals and no disruption to your workday. Whether it's a corporate office or a busy storefront, we make the outside view just as impressive as the inside one.

Building Washing

Exterior walls deal with more than the odd splash of rain. Dirt, dust, algae and city grime settle in slowly, making the building look older than it really is. Our commercial building washing service brings facades back to life using soft-washing techniques that gently but effectively remove surface build-up without damaging paint or materials. It’s the low-pressure way to make a big difference to how your building presents itself.

Roof Washing & Treatments

Moss and mould don’t just make a roof look neglected; they shorten its lifespan and invite costly problems. Our roof washing service helps remove years of growth, grime and moisture, and includes treatment options to slow down regrowth. It’s a preventative step that protects your property from avoidable leaks and structural damage, while keeping your roof looking tidy and well-maintained.

Gutter Cleaning & Sky Vac

If your gutters are blocked, it’s only a matter of time before the overflow becomes a problem. We use the SkyVac system, which allows us to clean gutters safely from the ground using a high-powered vacuum with a built-in inspection camera. It’s quick, effective and ideal for hard-to-reach places, all without disrupting your site or staff.

Pressure Washing

Carparks, entryways and outdoor footpaths get filthy fast. Oil stains, moss, chewing gum, tyre marks — you name it, we’ve cleaned it. Our pressure washing service is ideal for restoring concrete, paving, and other ground-level surfaces to a safer, more professional state. We use the right pressure for each surface to avoid damage while delivering maximum impact.
