The company delivers new construction, conversion, renovation, and restoration services across residential, institutional, commercial, and cultural-heritage segments, with a particular specialisation in social-housing renovations, schools, hospitals, and listed/heritage buildings. Its service portfolio is organised around five competencies: new construction (Nybygning), conversion (Ombygning), building renovation (Bygningsrenovering), restoration (Restaurering), and a specialised in-house Master Craftsman Department (Mesterafdeling) handling heritage projects such as the post-2022-fire reconstruction of Hyltebjerg Kirke and work at Designmuseum Danmark and Amalienborg.

The company operates exclusively on a project-based contracting model, winning work through competitive public tendering under totalentreprise (turnkey), hovedentreprise (main contractor), and integrated collaborative arrangements. Recent contract values range from 65 mio. DKK (Mændenes Hjem) to 500 mio. DKK (Moserne renovation of 560 apartments), with an active portfolio spanning AKB Rødovre, Lejerbo, Boligselskabet Sjælland, Gentofte Kommune, Københavns Kommune, Herlev Hospital, PFA Pension, Scandic Hotels, and Designmuseum Danmark. The company is a serial award recipient, including the Tømrerprisen 2024, two RENOVER Prisen nominations, and the Arbejdsmiljøprisen 2020 for apprentice safety programmes.

Einar Kornerup A/S is privately held by the Kornerup family (with Jens Kornerup as director and co-owner, grandson of the founder) and runs an apprenticeship pipeline of 15–17 trainees across bricklaying, carpentry, and concrete trades. Its current CEO, Jón Kristjánsson, was appointed on 1 September 2022 after rising internally from building manager (2013) to project chef (2019). The firm has no disclosed revenue, no public listing, and operates exclusively in the Danish market with a primary focus on the Greater Copenhagen and Sealand regions.
