Property Maintenance

Planned, reactive and emergency property maintenance services designed to keep your buildings fully functional. From small repairs to major works, our multi-skilled teams handle every aspect of upkeep – ensuring minimal disruption to your business and maximum value for money by handling jobs requiring multiple skillsets which typically means multiple contractors, visits and documentation. NIS’s ethos is simple:

One Team. One Workflow. One Goal.

If you want some time back, less admin and more time to run your business, here’s how we can help…

Roofing & Guttering

From leak detection and repairs to complete roof renewals, we protect your assets from the elements. Our teams install, repairs and maintain flat and pitched roofs, gutters, gulleys and downpipes to ensure long-lasting weather protection and compliance with building standards. Using drones where roof access is an issue we can often establish what work is required without the initial expense of a MEWP or scaffolding.

Masonry, Pointing & Rendering

We preserve and restore the structural integrity and appearance of your building envelope.

Our masons carry out brick and stone repairs, re-pointing and rendering, combining traditional techniques with modern materials for durability and aesthetics.

Electrical

Our qualified electricians can provide full electrical installations, testing, inspection and maintenance. We may be required to change a plug socket or fix a faulty light switch or install Cat6 cabling across a large-scale office refurbishment, we have the required competences to complete every project safely, efficiently and with minimal disruption to your operations.

Plumbing

From emergency leaks to complete plumbing installations, we deliver reliable services to keep your systems running efficiently. Our engineers handle hot and cold-water systems, waste pipework, boiler replacements, dead-legging to avoid Legionella and shower block or kitchen installations – ensuring optimum safety and hygiene at all times and minimising down-time.

Windows, Fascias & Soffits

We supply, install and maintain a wide range of window systems, fascias and soffits. Whether you need energy-efficient replacements, facade repairs, or timber sash windows for a period property, we help you by specifying the most appropriate solution to improve your building’s insulation, weather resistance and aesthetic appeal.

Plastering, Painting & Decorating

Our decorators deliver high-quality finishes for both interiors and exteriors through expert plastering, painting and decorating services. From wall repairs and skimming to full-scale redecoration projects, every job is completed with precision and attention to detail. We frequently work across communal areas in residential blocks, hotels and complete full office repaints, transforming tired or dated interiors into bright, refreshed spaces.

Flooring Installation

We install and maintain all types of flooring, from carpet tiles and vinyl to wood and safety flooring. Whether it’s as school gymnasium floor replacement, entire medical facility floor or a decadent reception area in a London office, our team ensures smooth, durable finishes suited to commercial, industrial or residential environments.

Walls & Ceilings

From partitions and suspended ceilings to repairs and upgrades, we provide tailored wall and ceiling solutions to transform your interior spaces. Our work improves acoustics, aesthetics and energy efficiency while meeting fire and building safety standards. In some cases, we may remove suspended ceilings to showcase HVAC features to create a cool-looking exposed industrial feel.

Heating, Air Conditioning & Ventilation (HVAC)

We design, install and maintain heating, cooling and ventilation systems that keep your environment comfortable and compliant. Our engineers ensure energy-efficient performance and reliable operation year-round, including servicing and emergency repairs.

Refits & Refurbishments

Whether modernising a workspace, upgrading facilities or reconfiguring layouts, our refit and refurbishment services deliver complete transformations.

We manage every stage, from design consultation to final handover – ensuring quality, safety and timely completion. For more information and examples of our work, take a look at our Projects division page.

Doors, Shutters, Barriers & Gates

We supply, install and maintain a comprehensive range of physical security systems, including roller shutters, access barriers and security gates.

Our team also installs a variety of doors, from louvred external security doors to FD60-rated fire doors – ensuring the right level of protection is selected for your specific requirements. Every solution is designed to provide lasting security, ease of operation and complete peace of mind.

Fire Safety & Security

Protecting people and property is at the heart of what we do. Following a Fire Risk Assessment (FRA) we’ll make recommendations which may include improving fire stopping measures, replacing or maintenance of fire alarms, extinguishers or emergency lighting. If you’re concerned about the vulnerability of your site, we’ll conduct a Security Risk Assessment to identify threats to your assets and may suggest key measures, such as the installation of window grilles, anti-climb collars, CCTV, access control and intruder systems ensuring compliance with all relevant safety regulations.
