About us
Consti Oyj is a publicly listed Finnish company (Nasdaq Helsinki) and self-described leader in repair and renovation construction in Finland, focused on effectively renewing the country's existing building stock — housing companies, corporate properties, and public-sector buildings — rather than new construction. The group provides specialists across pipeline renovation, façade and roof renovation, window renovation, balcony renovation, building technology (heating, water, electricity, ventilation, fire safety, and automation systems), and yard/environment construction for residential, industrial, commercial, hotel, office, and public buildings.
For housing companies specifically — Finland's apartment co-operative ownership structure covering much of the country's urban housing stock — Consti offers full pipeline ('putki') renovations, façade and roof renovation, microbial/mould damage repair, and a dedicated 'Eco Consti' energy-saving solutions line covering solar power (aurinkosähkö) installation and EV charging infrastructure for existing apartment buildings undergoing renovation. The company frames sustainable development and climate-change mitigation as core to its corporate strategy, and holds RALA (Finnish construction quality/competence) certifications for competence, quality, safety, and environmental management, alongside 'Avainlippu' (Key Flag, denoting Finnish-made services) and 'Luotettava Kumppani' (Reliable Partner) status.
Consti operates through several business areas — Housing Companies, Corporations, Public Sector, and Building Technology — each led by a named director, and publishes a formal sustainability ('vastuullisuus') report and whistleblowing channel. Consti Oyj is headquartered in Finland and can be reached at +358 10 288 6000 or asiakaspalvelu@consti.fi.contact
