Plomberie JL

What Plomberie JL does

Plomberie JL Inc. is a third-generation, family-owned mechanical contractor founded in 1989 by Jules Lamoureux and headquartered in Longueuil, Quebec. The company provides plumbing, hydronic heating and cooling, natural gas, and building mechanics services across residential, commercial, and industrial end markets in the Greater Montreal area and broader Quebec, employing more than 120 field and office staff. Its service portfolio covers new construction plumbing, renovation work, on-demand service calls (pipe unclogging, camera inspection, pipe thawing, water heater replacement), and recurring annual maintenance contracts for plumbing, gas, heating, and cooling equipment.

Technically, the firm differentiates on specialized hydronic and high-efficiency systems, including radiant floor heating, snow melting, geothermal installations, four-pipe combined heating/cooling hydronic systems, and high-performance mixed water (eau mitigée) systems using heat pumps, water towers, and high-efficiency boilers. It has adopted BIM (Building Information Modeling) construction workflows to integrate with general contractor and developer processes on large multi-unit residential and commercial builds, and holds preferred partnerships with Bradford White, A.O. Smith, and Lochinvar for water heating and boiler equipment, alongside a natural gas installation relationship with Energir. Regulatory standing includes RBQ licensing and CMMTQ master pipefitter credentials.

Commercially, Plomberie JL generates revenue primarily through project-based professional services for developers and general contractors (e.g., Sotramont, Prevel, Trigone, Cogir, Devimco, Construction Quorum) on large multi-unit residential, commercial, retail, and select industrial builds, layered with a recurring maintenance contract stream and a distributed base of on-demand residential service calls. Pricing is not publicly disclosed; service requests are captured via website forms and a dedicated phone line. Operations are concentrated in the Greater Montreal region including Longueuil, Brossard, Boucherville, Saint-Bruno-de-Montarville, Saint-Lambert, and Saint-Hubert, with project reach extending to other Quebec cities such as Griffintown, Dunham, La Prairie, Mascouche, Matane, and Rimouski.
