What Réno'Line does

Réno'Line is a French general renovation contractor (entreprise générale du bâtiment) headquartered in Colmar at 6 rue de Mulhouse with an operational base in Herrlisheim-près-Colmar, operating primarily across the Haut-Rhin department and broader Alsace region. Founded in 2017 and operating with a 1-10 employee headcount, the privately held company is led by Julien Dietemann and delivers turnkey residential and light-commercial renovation projects for individual homeowners and local professionals (shops, real estate promoters, medical practices). The service range spans light interior refresh, complete renovation, energy renovation, heavy structural renovation, custom timber-frame extensions, and attic conversions.

The company's service portfolio is organized into core turnkey offerings and specialized technical services. The technical stack centers on a general contractor coordination model that aggregates all trades, augmented by 3D design visualization produced during the design phase to preview renovation outcomes, and the use of ecological and durable materials including wood fiber and hemp insulation, low-VOC paints, Fermacell dry screeds (recycled cellulose fibers, chemical-binder-free), and Atlantic air-to-water heat pumps. RGE certification enables customer access to French government financial aids for energy renovation work, and is a core go-to-market enabler.

Revenue is generated entirely through project-based, one-time all-inclusive fees that bundle design, coordination, and execution of multiple trades. Published pricing ranges from €200-500/m² for light refresh to €1,100-2,000/m² for heavy structural renovation, with representative project values of €25,000-€70,000 for a 100 m² light renovation and €132,000-€240,000 for a 120 m² heavy renovation. Go-to-market is sales-led: customers initiate contact via website forms or phone, receive a free on-site consultation and quote, and are then supported by a dedicated project referent from quote through completion. Marketing combines a content-rich website, organic social on LinkedIn, Instagram, and Facebook, and bottom-of-funnel credibility through Google Reviews and Trustindex verification.
