What Rakennuspalvelu J.Martti & Co Oy does

Rakennuspalvelu J. Martti & Co Oy is a privately held Finnish renovation and new-construction contractor founded in 1991 and headquartered in Littoinen (Turku). The firm specializes in technically demanding construction projects, including museum and heritage renovations, housing-company pipe replacements (linjasaneeraus), facade and basic renovations of residential apartment buildings, and commercial fit-outs for office, retail, healthcare, and industrial customers. Its portfolio spans six interconnected service lines: new construction (uudisrakentaminen), commercial construction (toimitilarakentaminen), renovation (korjausrakentaminen), pipe renovation (linjasaneeraus), KVR turnkey contracting, and project-management contracting (PJU). References page lists engagements from 2006 to 2026 across residential, healthcare, education, retail, banking, industrial, and public-sector clients, including As Oy Puistokatu 3, Turun Ylioppilaskyläsäätiö, Kurjenlinnan sairaala, Gigantti Oy, Pihlajalinnan lääkäriasema, Burger King Skanssi, Danske Bank Turku, and Amomatic Oy.

The company's core technology stack is light: a proprietary company-specific quality management system (yrityskohtainen laatujärjestelmä) standardizes execution, and the firm deploys the HomeRun.net digital platform across all pipe-renovation projects to manage apartment-specific product selections, room-card approvals, and multi-channel resident communications. It holds RALA competence certification, uses the RALA-palaute feedback system, maintains Suomen Asiakastieto Platina creditworthiness continuously from 2017 through 2025, is a member of Rakennusteollisuus RT, and is enrolled in the Vastuu Group trust-verification service. Approximately 15 staff are listed across office and site roles.

The business model is project-based construction contracting under main-contract (pääurakointi), KVR turnkey, or project-management (PJU) delivery formats. Pricing is custom-quoted per project with no public price list; customers initiate engagement via the company website, phone, or email and negotiate contracts tied to scope and milestone completion. GTM is sales-led and relationship-driven, with demand generated primarily through the company website, direct outreach, and referrals from existing clients in the Turku economic area, with project-based expansion to Tampere and Helsinki. Customers include housing companies (As Oy), commercial property owners and tenants, public-sector and institutional buyers, and real-estate developers seeking single-point-of-contractor accountability.
