Hammer Og Sag

Hammer og Sag AS is a master builder firm that takes on new builds, extensions, renovation and bathroom construction, along with smaller service jobs and scaffolding rental. It coordinates the various trades through a network of partner firms and offers a total delivery package in which the client deals only with the company during the construction period.

Customers are private homeowners. Renovation work includes replacing facades, windows and roofs, and can include added insulation and sealing with energy reports prepared as a basis for ENOVA support applications. The company also builds architect-designed detached houses, including projects over 1000 m2.

The company was founded in Asker in June 2007 by master builder Magnus Robertsen. It has an office and warehouse on Hvalstad, and a branch in Ringerike, opened in 2016 by master builder Alexander Taxt Horne. The website lists 8 employees: two master builders, four skilled workers and two apprentices. Certifications include central approval for responsibility for carpentry work and a wet room certificate.
