Precision in Heating, Ventilation & Sanitary.
Rubicor HLS provides complete, senior installation crews for contractors in Germany and Austria — executed to German quality standards, from mobilization to signed-off hours.
A partner your site management can rely on.
We combine veteran craftsmanship with the paperwork discipline German sites expect — crews that deliver, and documentation that holds up.
Senior crews
Every installer brings 15–30 years of experience from demanding German and Austrian projects. No trainees on your site.
German standards
We work to VDI, DIN and DVGW — clean execution with documentation included as standard, not as an extra.
Transparent hours
Hours are logged daily and signed off by you. Invoices are generated from signed time sheets only — no surprises.
Compliance sorted
A1 posting certificates, proper employment contracts and insurance — the paperwork is ready before the crew arrives.
Three disciplines. One standard.
From inquiry to signed hours.
A clear four-step process — built the way contractors actually work.
