Seal the Leaks. Then Insulate.
Attic, Spray Foam & Home Insulation for homes and small buildings across Canada and the US.
Calenta focuses on one part of the house: keeping heat in during winter and out during summer. Attic insulation, spray foam, blown-in insulation, air sealing, and basement and crawl space insulation. When it is missing or done badly, you feel it as cold rooms, drafts, ice dams on the roof, an upstairs that bakes in July and a furnace that runs all the time.
The most common mistake is piling more insulation on top of the problem. Insulation slows heat, but warm air still pours through gaps around pipes, wires, pot lights and the attic hatch, and an attic with blocked vents traps moisture. So every request starts with a look at the whole picture: what insulation is there now and how deep, where the air leaks are, how the attic is vented, and the state of the basement or crawl space.
You describe the house once through the quote form. A specialist who works in your area follows up, looks at the house and gives you a written quote with the areas, materials, target R-values and air sealing. Homeowners, small multi-unit owners and small commercial building owners across Canada and the US can request a quote.
