Wall insulation for homes that already have walls
Not every home upgrade needs a hammer. For single-story homes with unfinished cavities — older Salem stock, 1970s builds — blown-in wall insulation is one of the best value-for-effort upgrades we install. We drill small holes, fill the cavities, and leave your drywall alone.
What this means for your home
Not every home upgrade needs a hammer. For single-story homes with unfinished cavities — older Salem stock, 1970s builds — blown-in wall insulation is one of the best value-for-effort upgrades we install. We drill small holes, fill the cavities, and leave your drywall alone.
- Blown-in cellulose or fiberglass, chosen for the wall cavity type
- Small drilled holes in the drywall, patched and painted when done
- Works in single-story homes with standard stud spacing — most of the older Salem and Keizer stock
- Not for multi-story homes with load-bearing upper walls — we’ll tell you that upfront without wasting your time
- Done in conjunction with air sealing where it makes sense
Why TCS
“Insulation only works if it’s installed for the way your house actually holds air.”
We look at air leaks first, moisture second, and insulation depth third. That’s why a TCS install stays comfortable and energy-efficient.
Single-story homes
If you’ve got a ranch or a 1960s–90s two-flat, this is probably for you.
Honest fit check
If your home isn’t a candidate, we say so before you book.
Small holes, clean finish
We map the cavities before we drill, so the patching looks right.
How we work
The TCS process, start to finish
We check whether your walls can actually take it
Not every wall is a candidate. Two-story homes with load-bearing party walls, or walls with lots of wiring and plumbing, may not be. We look at floor plans and a physical spot-check before we quote.
We map the cavities first
We mark the stud bays on the wall so we know exactly where the holes go. This is the step most people skip and wish they didn’t — it’s why the patching and paint come out clean.
We drill, fill, and seal the perimeter
Each hole is small, we fill the bay, and we check for any leaks at the top of the wall that the insulation alone won’t cover. Those leak points get caulked or foamed in the same visit.
We patch, paint, and hand it back
Holes get patched to match the drywall, touch-up paint, and a walkthrough. Total mess is a patch kit, not a construction site.
Good to know
Questions people ask before booking
Usually no. Two-story homes with a finished or load-bearing upper wall can have cavities that are harder to access or not isolated enough to fill effectively. If you’ve got a single story, or a split-level where the lower wall can be accessed from one side, that’s the sweet spot. We’ll check your floor plan before quoting.
No. The whole point of this job is small drilled holes, fill the cavity, patch, and paint. If a wall needs to come down for another reason, we’d tell you it’s a separate project and quote it as such.
You usually notice it first on the draftiest wall — the one that was cold to the touch in winter. The wall gets a bit more stable thermally, which is the point. It won’t be as dramatic as a full-wall spray-foam job, and we don’t oversell it.
Depends on the wall and what else we’re doing. Most single walls are a few hours of work including patching. For a full single-story home, plan on a couple of days. We’ll give you a real number once we know the scope.
