Groentech Security Services
Nathan visits every site himself — a detail commercial clients specifically call out as the difference-maker.
That matters most for commercial and multi-tenancy properties where security needs aren't obvious from a floor plan. The business is relatively new (under two years), but reviewers note Nathan's prior industry experience directly, and the scope of work described — including an 18-storey mixed-use building — suggests the team isn't learning on unfamiliar jobs. With only 12 total reviews to draw from, you can't call this a long track record, but every review is five stars with no exceptions in the sample. If you're a building manager or commercial property owner, it's worth asking Nathan to visit the site before accepting a quote — that's apparently where this business differentiates itself most.

About Groentech Security Services
Nathan leads the team at Groentech Security Services, and his name comes up across virtually every review — specifically for taking time to visit sites, understand the actual layout, and explain options before quoting. That site-first approach stands out in a category where competitor quotes are often done at arm's length without inspection. The team handles both residential and commercial security, but the commercial work is notably complex: one project involved cameras, monitors, lift and door access systems, fob devices, and full security data wiring across an 18-storey apartment building with 115 apartments and 5 commercial lots. For smaller residential jobs, like camera installs on investment properties, turnaround is fast and communication is direct. Installations are consistently described as leaving the site neat and tidy, which matters in occupied offices and childcare centres where mess creates problems after the crew leaves. Worth knowing: Nathan brings years of industry experience from prior roles, which means the business is newer than his personal expertise — something reviewers specifically flag as reassurance.
Best for: complex commercial and multi-tenancy security installs, investment property CCTV setups, and business owners who want the person quoting the job to also be the one running it on-site.

What types of properties does Groentech Security Services work on?+
Reviews cover a wide range — from investment properties and childcare centres through to an 18-storey apartment complex with 115 apartments, 5 commercial lots, and full lift and door access integration. The team appears equally comfortable on small residential jobs and large-scale commercial projects. If you have a complex or multi-tenancy site, it's worth contacting Nathan directly, as he reportedly visits sites before quoting rather than pricing from plans alone.
Who will actually show up to do the work?+
Nathan is named in nearly every review as the person leading the job — quoting, attending the site, and overseeing installation. Reviewers describe him as knowledgeable and customer-focused. There are references to 'his team' being involved on larger commercial projects, though individual team members aren't named in the reviews we reviewed.
How does Groentech's pricing compare to other security companies?+
One commercial client — a building manager overseeing a large apartment complex — specifically noted that Groentech's quote came in significantly lower than a competitor's bid for the same scope of work. There isn't enough pricing data across multiple reviews to call this a consistent pattern, so treat it as a useful data point rather than a guarantee. It's worth getting a comparison quote if budget is a factor.
Is the business experienced enough for a large or complex security project?+
The business itself is under two years old, but one reviewer specifically flagged that Nathan brings years of hands-on experience from prior roles in the security industry. The completed project list includes multi-storey commercial buildings with integrated CCTV, access control, fobs, and lift systems — suggesting the team has handled technically demanding scopes. For large projects, ask Nathan to walk your site before finalising any scope of works.
What areas does Groentech Security Services cover?+
The business is based in Clarkson, WA. Reviews mention projects in Gidgegannup and other Perth metro locations, suggesting they travel across the broader Perth region. The reviews don't specify a firm service radius, so if you're outside the northern suburbs, it's worth confirming coverage and any travel costs directly with the business.
