Blown-In Attic Insulation
Blown-in attic insulation spreads an even layer over the entire attic floor, around wires and trusses, while a clean existing layer stays in place.
How it works and what it costs
Every service on this page follows one order of work: the visit, the sealing, the baffles, then the insulation. Most homes need two or three of them together, and the visit tells us which. Pick the job that sounds like your attic, or phone and we can sort it out together over the line. A townhouse top-up, a cold room over the garage and a vaulted great room each have their own page below, with the method and the usual price range.

Attic insulation removal vacuums out wet, dirty or flattened material, leaving a bare floor that can be sealed and filled again from scratch.

Attic air sealing plugs the gaps in the ceiling so warm house air stays downstairs, and it happens on every job before anything new goes on top.
How it works and what it costs
Attic ventilation moves outside air in at the soffits and out near the ridge, so the attic stays cold and dry in winter and less hot in summer.
