Fönster & Hantverk

What Fönster & Hantverk does

Fönsterhantverk i Östergötland AB is a privately held Swedish crafts and restoration company founded in July 2007 (originally as Fönster & Hantverk) and headquartered in Linköping, Sweden. The company specializes in the renovation and new fabrication of older windows, doors, and joinery in cultural heritage buildings—typically more than 100 years old—using traditional materials such as linseed oil paint, cultural (historically blown) glass, tight-grained timber, and period-appropriate hardware (kulturbeslag). Work is frequently performed under antiquarian supervision to meet Swedish heritage preservation requirements, and the company operates from a workshop in Linköping while serving clients across Östergötland, Stockholm, Uppland, Norrköping, Vadstena, and Karlsborg.

The service portfolio is anchored by three core offerings—Window Renovation, Door Restoration, and Lead-Framed Window Work (blyinfattningar), including stained glass—with supporting services in wood repair, new fabrication to original templates, energy-efficiency upgrades for heritage windows, rust protection for gates and iron structures, and decorative painting techniques such as marmorering (marbleizing) and ådringsmålning (graining). The technical foundation is in-house traditional craftsmanship across wood, glass, paint, and iron trades rather than digital or automated production; the energy-efficiency offering is the principal bridge between heritage compliance and modern building performance.

The business operates on a project-by-project, quote-based revenue model with no public pricing. Customers are acquired primarily through direct outreach via the company website, phone, email, and workshop visits, with a notable portion of revenue anchored by a multi-year framework agreement (ramavtal) with Statens Fastighetsverk (SFV) covering state-owned heritage buildings including Stockholm Palace, alongside work for the Church of Sweden, housing cooperatives (Brf), regional real estate owners (LF Östgöta), general contractors (NCC), and private heritage property owners. The firm is founder/management-owned with no disclosed external investors or funding events, operates as a small workshop-based business, and has shown progressive rather than aggressive growth since inception.
