What SEGUIN91 - Cheminées des 2 Vallées - Groupe ELMAT does

SEGUIN91 — Cheminées des 2 Vallées is an RGE-certified fireplace and heating installer and multi-brand distributor headquartered in Palaiseau, Île-de-France. Founded in 1992 and acquired by Laurent Hermesse in 2016, the company has scaled revenue roughly 9x over the subsequent seven years to a current run-rate of 400+ installations per year, accumulated over 8,000 customers and 6,000+ completed projects over its history. The business sells and installs wood-burning stoves and inserts, pellet appliances, gas units, pellet boilers (Thermolab), and indoor ventilation systems (Vitalome), drawing on exclusive or privileged distribution rights for premium brands including Seguin (25+ year partnership), JC Bordelet, Hwam, Piazzetta, Vulx, Axis, and Thermolab.

The operating model is vertically integrated around in-house certified technicians — the firm explicitly does not subcontract installation work — which underpins its RGE Qualibois certification and access to French state renovation subsidies (MaPrimeRénov', CEE). A subsidiary, Brun Entreprise (acquired 2021), handles chimney sweeping and after-sales maintenance, converting one-off installations into recurring service relationships. The customer base is predominantly long-tail residential, with periodic B2B project exposure (notably a 200-unit Center Parcs / Pierre et Vacances contract).

Commercial activity spans Île-de-France as the core market, with an active geographic extension into Normandy and Le Perche targeting the secondary-residence segment. Professional-grade customer financing is offered via the Eldo platform. The company operates as part of the Seguin Club / Groupe ELMAT dealer network, and carries a 4.8–4.9/5 Google rating as a reputation asset.
