01THE PROBLEM
These Houses Were Built to Breathe. Now They Just Bleed Heat.
Coal-heated homes were framed loose on purpose, drafts were the ventilation plan. A century later the same bungalows run modern furnaces against uninsulated roofs and open chases. No housing type in the metro repays an attic upgrade faster than Englewood’s oldest blocks.
AAttics that were never insulated at all
Open joists, a skim of ancient fill, sometimes nothing but dust: the standard finding in Downtown and Bates-Logan attics. Starting from zero means every inch we add is pure gain, comfort changes the first night.
BBalloon framing pulling air up the walls
Pre-1930 balloon framing leaves wall cavities open from basement to attic, every wall becomes a chimney. Capping those chases before insulating is non-negotiable, and it is the step generic crews skip.
CKneewalls and dormers leaking sideways
Story-and-a-half bungalows lose heat through kneewalls and dormer cheeks as much as through the flat attic. Those angled spaces need foam or careful batt-and-baffle work, flat-attic thinking fails here.
DKnob-and-tube: respect before depth
Live knob-and-tube wiring cannot be buried in insulation, that is code and common sense. We identify it during inspection and give you the straight path: what can proceed now, and what an electrician should retire first.
02THE FIX
A Century-Home Attic Has Three Jobs. We Do All Three.
Seal the chases, handle the angles, then add depth. Here is how the two halves of the work compare:
03WHAT TO EXPECT
Old-House Careful, One-Day Fast.
How an attic day goes in a typical Englewood home:
Knob-and-tube status confirmed, plaster ceilings assessed, and runners laid through the house. Old homes get inspected before they get touched.
Wood shavings, old rock wool, and degraded layers vacuum out through a sealed hose so new material sits on a clean, known deck.
Balloon-frame wall tops get rigid blocking and foam, the chimney gets fire-rated clearance flashing, and the hatch gets rebuilt tight.
Kneewalls and dormer cheeks get their foam or batts before cellulose floods the flat to 14–17 inches, R-49 to R-60 settled.
Depths photographed, chases and chimney details shot for your records, floors cleaned. A 1920s house with a 2020s attic by dinner.

"Our 1924 house near Romans Park had bare joists up top and frost on the bedroom ceiling corners every January. One day of work: sealed, foamed kneewalls, R-60. The upstairs went from the coldest floor to the warmest."

05QUESTIONS
Attic Insulation in Englewood, Answered Straight
The same R-49 to R-60 as any Zone 5B home, but the journey is longer: many bungalows start at effectively zero. That is good news for payback, the first R-20 you add saves more than the last R-20 anywhere else.
Starting point, geometry, sealing scope, and wiring era set the number. A simple ranch top-off is the lightest ticket; a bungalow with kneewalls and balloon chases is more involved and still one of the best-returning projects in the metro. Everything is itemized in writing first.
No, live knob-and-tube cannot be buried, full stop. We identify it during inspection, insulate the areas that are clear, and coordinate honestly on retiring the old circuits before finishing the rest. Safety sequencing is part of the service, not an upsell.
They are the short walls between living space and the roof in story-and-a-half homes, Englewood’s signature floor plan. Left bare, they leak heat sideways all winter. Foaming or batting them properly is often half the comfort gain in these houses.
One day for most Englewood attics, including sealing. Kneewall and dormer work can add a half-day, and any old-fill removal happens the same visit. You get the schedule in writing with the quote.
Almost certainly, that pattern is warm, moist indoor air hitting a freezing roof deck through an uninsulated ceiling. Sealing the leaks and adding real depth keeps the deck cold and dry on the outside and your ceiling warm on the inside, which ends the frost cycle.
