We build.
We repair.
We protect.

Commercial buildings fail in predictable ways: concrete spalls, sealant joints reach the end of their service life, roofs leak where drainage was undersized, and height safety systems lapse between certifications. Allied Commercial exists to fix all of it under one contract. From offices in Brisbane, Sydney, Melbourne and Perth, our crews deliver construction and remediation, facade services, commercial roofing and height safety across 17 Australian cities.

Concrete remediation and commercial repairs

Concrete cancer does not stop at the patch you can see. Our remediation crews break out drummy concrete, treat corroded reinforcement, and reinstate to AS 3600 and EN 1504 specifications with engineering sign-off where certification is required. For everything between major projects, the commercial repairs team handles planned maintenance and reactive works for portfolios from a single phone call.

Facade repairs, glazing and audits

Facade work is access work. Allied self-performs rope access, which means facade repairs, commercial glazing replacement and high-rise window cleaning proceed without the cost and street disruption of scaffolding on most buildings. Where owners need a documented starting point, a facade audit maps every defect with severity ratings and budget pricing, turning engineer findings into a works programme a committee or board can approve.

Commercial roofing that ends the leak cycle

Most recurring leaks are drainage and detail failures, not holes. Our leak detection service uses thermal imaging and controlled water testing to find the true entry point before any repair is priced. When roofs reach end of life, re-roofing crews replace them with Colorbond and Zincalume systems installed to AS 1562.1, staged so warehouses, retail centres and offices keep operating underneath.

Height safety, certified and documented

Every trade above two storeys depends on compliant anchorage. Allied designs, installs and certifies anchor points, static lines, walkways and guardrails, and our ATA Certified technicians inspect and recertify systems to AS/NZS 1891.4:2025 and AS 5532:2025 with digital records. Sector-specific delivery for strata, commercial property, retail, industrial and government clients is documented in our field methodology and standards reference.
