Door brand guide · Perth
Perth's own timber, aluminium and Thermopanel door manufacturer, kept running by local technicians: panels matched, springs re-tensioned, and honest advice on repair versus replace.

Danmar
Danmar garage doors are the timber, aluminium and Thermopanel sectional doors built locally in Perth, and Capital Garage Doors repairs, services and replaces them across the whole metro area. Being a genuinely local manufacturer means matching a damaged timber slat, aluminium panel or Thermoflat section is usually straightforward rather than a special order from interstate. A full service to keep a Danmar door balanced and running smoothly is from $140 + parts, with same-day visits available for anything more urgent.

Danmar is one of the few garage door brands actually made in Perth rather than shipped in from an interstate or overseas factory. The business has been building doors locally for more than 35 years, working in natural timber, contemporary aluminium and its own Thermopanel insulated steel, plus a side-slide sectional design for garages where a standard overhead door won't fit. That local manufacturing base is a real practical advantage: when a timber slat, an aluminium panel or a Thermoflat section needs matching, the replacement is usually cut from the same local supply chain rather than sourced from an overseas warehouse months later.
Danmar doors turn up across a wide range of Perth homes, from character properties finished in natural timber to newer builds running the flatter Thermoflat and aluminium ranges. Timber doors need a different kind of care than steel — Perth's sun and dry heat can crack or warp an unsealed timber panel over the years, while the aluminium and Thermopanel ranges are more prone to the usual spring, roller and track wear every sectional door sees. The calls we get most are a timber door that's swollen or sticking on its tracks, a spring that's lost tension, and rollers worn out from a sandy driveway.
Because Danmar manufactures locally, we can genuinely repair rather than replace in most cases — timber slats, aluminium sections and hardware are sourced through the same local supply the doors were originally built from, so a repaired door looks and performs like the original rather than a mismatched patch. When a timber door has warped beyond a straightforward fix, or a decades-old Danmar has simply reached the end of its structural life, we'll say so plainly and quote a straightforward replacement rather than pouring good money into a door that won't hold a repair.

Recognise one of these? Tap through for what causes it and what the repair involves.
Danmar's local Perth manufacturing means matching a damaged timber slat, aluminium panel or Thermopanel section is rarely a special-order problem — we can usually source the exact profile and finish through the same local supply chain the door was built from, rather than guessing at an interstate equivalent. Springs, cables and hardware are replaced with correctly rated components for the door's size and weight, not a generic universal kit.
A new door is the honest answer when a timber door has warped or rotted beyond a structural repair, or a Danmar door from decades ago has simply reached the end of its service life. In those cases we quote a straightforward Danmar replacement in timber, aluminium or Thermopanel, or point you to the full range of doors we supply and install across Perth at new garage doors in Perth — whichever suits your home and budget.
