4 recaps
Insulation recaps are episodes tagged with insulation, spray foam, or air sealing. Those tags name the same envelope work at different steps. A recap is listed when it carries one of them.
This Old House · S47 E24
In Walpole, a two-unit ranch gets a code-rated firewall, a shared hydro-air HVAC system, whole-house water filtration, and a cold-joint injection that makes old-meets-new basement walls honest. Then Kevin and Tom tour a finished attic ADU in Dorchester—proof that 700 square feet can feel like a yacht.
This Old House · S47 E20
The Needham Victorian wraps on a 24-inch snow day. Charlie installs the mortise lockset Tom patched into the original front door, Kevin tours the open kitchen, mudroom, primary suite, and finished basement, and Richard explains why the old furnace stayed while attic foam and a new heat pump did the heavy lifting.
This Old House · S47 E15
HVAC gets targeted upgrades instead of a gut job, Charlie chooses closed-cell spray foam for the third floor, and Tom proves that proper window flashing is a lost art worth finding.
This Old House · S47 E5
Building science experts seal a house with pressurized mist (yes, really), FEMA tackles the hazardous trees still looming overhead, and Mark gets a history lesson at one of Asheville's most iconic hotels.
