Boiler Repair & Service

Providing fast and reliable Boiler Repair and Service in the Clarence-Rockland, Hawkesbury and Embrun area since 1976

We have worked on hundreds of boilers in Glengarry, Prescott & Russell and use a thorough boiler repair and service checklist when assessing your boiler problem. When you call us, you will always speak with an employee (during regular business hours). Once our technician arrives on-site, they’ll start diagnosing your boiler problem. Common boiler problems include no heat, leaking, odd noises, a failing pilot light, kettling (steaming due to sludge and lime scale build up), frozen pipes and loss of pressure. Once the problem has been diagnosed, our licensed technician will provide you with an easy to understand explanation and give you honest advice on repair and replacement.

We’re experienced with all major brands including:

  • Bosch
  • Lennox
  • Crown
  • Viessmann
  • Weil-McLain
  • Lochinvar
  • Buderus
  • Burnham
  • Laars
  • Baxi
  • NY Thermal

In addition to boiler repair, we also offer services that can significantly expand the lifetime of your boiler. Our boiler restoration services include boiler refractory, burner and burner control service, annual cleaning and inspections,structural repair including watertubes and firetubes, boiler and condenser retubing and combustion analysis. Our annual cleaning and inspection will ensure that most problems are found before they shut down your boiler and leave you in a “no heat” situation.
