Insulating Jenkintown's Older Homes the Right Way
Insulating a Jenkintown Victorian is a sequencing problem before it's an insulation problem. Many houses along the Old York Road corridor still hold knob-and-tube-era wiring and balloon-framed walls, and both need attention before any cellulose gets blown in. Our crews handle the full sequence — wiring verification, air sealing, then dense-packed walls and attic insulation — often paired with a heating upgrade in the same project.
Knob-and-tube and balloon framing: the work before the work
Two features of Jenkintown's older housing stock have to be dealt with before insulation goes in. Knob-and-tube wiring sheds its heat to open air by design, so burying live circuits under insulation creates a fire hazard — any active knob-and-tube must be confirmed dead or remediated first. Balloon-framed walls are the second issue: stud cavities that run open from basement to attic move air through the house like chimneys, so dense-packing without sealing the tops and bottoms of those channels forfeits much of the benefit. We work in order — verify the wiring, seal the bypasses, insulate the walls and attic — because insulation installed out of sequence underperforms, or worse.

Insulation Questions — Jenkintown, PA
Can you insulate a house that still has knob-and-tube wiring?
Not over live knob-and-tube — energized vintage wiring buried under insulation is a fire hazard. The circuits must be verified dead or remediated first, and we build that check into every older-home insulation project.
What is balloon framing, and why does it matter for insulation?
Balloon-framed walls have stud cavities that run open from basement to attic, letting air rise through the whole wall like a flue. Sealing those channels before dense-packing is what makes the insulation actually perform.
Can walls be insulated without tearing out my plaster?
Yes — dense-pack cellulose is installed through small holes that are patched afterward, so original plaster and trim stay in place.
Should insulation happen before or alongside a heating upgrade?
Alongside is often ideal: air sealing and insulation shrink the heating load, which can allow the new system to be sized smaller and run more efficiently. Our team can schedule both as one Jenkintown project.
