Where does a bungalow actually need foam?
In pre-war homes the losses hide in the angles. Here’s where foam earns its keep in the Englewood houses we assess:

The Brands Behind Every Grizzly Install
We don’t install mystery material. Every Arvada project uses products from the industry’s most trusted manufacturers.
01THE PROBLEM
Plaster Outside, Nothing Inside. Foam Fixes That Without Demolition.
You cannot batt a two-inch cavity or dense-pack a blocked one, and nobody wants their 1920s plaster opened up. Injection and spray foam deliver insulation into the spaces old construction left empty, through small openings, at R-values fiber cannot reach per inch.
AKneewalls radiating cold into bedrooms
The upstairs bedrooms in a story-and-a-half bungalow sit inches from the roof behind bare kneewalls. Closed-cell foam on those short walls and slopes is the single biggest comfort move in Englewood’s signature floor plan.
BCentury-old rims above damp cellars
The rim joist over a stone or early-concrete foundation leaks air and wicks moisture. Two inches of closed-cell seals and insulates the whole band, one morning, decades of benefit.
CCavities too shallow for anything else
Some Englewood walls were framed at depths no batt fits and dense-pack cannot reach code in. Injection foam fills them completely through small patched openings, plaster intact, cold walls retired.
DPorches that became rooms, but not warm ones
Half of Englewood’s sunrooms and back bedrooms started life as porches, enclosed but never insulated. Foam brings those thin-walled add-ons up to the standard of the house around them.
02THE FIX
Closed-Cell, Open-Cell, Injection: Old Houses Use All Three.
The chemistry follows the assembly. Here’s the honest split, and where cellulose still beats them all:
03WHAT TO EXPECT
Small Openings. Big Difference. No Demolition.
A foam day in an Englewood bungalow, start to finish:
Original floors, trim, and plaster get masked and padded before anything else. Old-house work starts with respect for what cannot be re-bought.
Sagging kneewall batts and cellar debris clear out so foam bonds to clean framing, adhesion is everything in this work.
Century-old lumber gets moisture-metered and temperature-checked; injection ports get drilled and mapped. Foam on unprepared old wood is a callback waiting to happen.
Closed-cell goes onto rims, kneewalls, and slopes in gauged lifts; injection foam fills the closed cavities port by port until each one reads full.
Ports patched flush and ready for paint, overspray trimmed, thickness documented. Re-entry after the cure window, typically the same evening.

"The upstairs of our 1919 house near Cushing Park was a freezer, bare kneewalls the whole length. They foamed the walls and slopes and injected the shallow cavities in a day. Same plaster, same trim, completely different winter."

05QUESTIONS
Spray Foam in Englewood, Answered Straight
Because pre-war construction created spaces nothing else can insulate properly: two-inch cavities, blocked stud bays, kneewalls inches from the roof, rims over damp cellars. Foam reaches all of them through small openings at double fiber’s R-value per inch, without opening plaster.
Geometry sets it: board feet across kneewalls, rims, and slopes, plus per-run pricing for injection work. A rim-and-kneewall package on a bungalow is a moderate ticket with an outsized comfort return. Line items come in writing after the on-site measure.
No, protecting the plaster is the point. Foam enters through small drilled ports at controlled pressure, each port is patched flush and paint-ready afterward, and the wall face is never opened. It is the least invasive way to insulate a finished old wall.
Yes, with proper process. We verify substrate moisture and wiring condition first, knob-and-tube gets addressed before foam, ever, and application runs in controlled lifts with ventilation. Cured foam is inert and compatible with historic framing.
Most Englewood foam projects finish in one day: masking and prep in the morning, application midday, patch and cure check by afternoon. Re-entry follows the cure window, usually the same evening.
The upstairs half-story, immediately, kneewall foam transforms those bedrooms. Converted porches and rooms over cellars come next. Anywhere your house currently feels like the outside is winning is exactly where foam works hardest.
