Saline homes split into two eras, and both lose heat through the attic. The older stock around downtown and Michigan Ave was framed long before anyone air-sealed a ceiling, and the subdivisions that filled in south and east of town through the 1990s and 2000s were insulated to the code of their day — thinly, by today’s standard, and almost never air-sealed. The same Washtenaw County crew that handles our Ann Arbor attic insulation work covers Saline, Pittsfield Township, Lodi Township, York Township and Milan every week.
Why Saline Attics Underperform
The century homes near downtown have the classic problems: open wall chases that run from basement to attic, plaster ceilings punctured by generations of wiring, and original hatches that leak air like an open window. In a snowy Washtenaw winter that becomes a chimney — warm air out the top, cold air pulled in at the sills, and a furnace that never rests.
The newer neighborhoods have a different version. Complex rooflines, bonus rooms over garages, cathedral great rooms and HVAC in a vented attic — builder-grade blown-in that has settled, minimal air sealing, and ductwork leaking into unconditioned space. Ice dams on the north eaves after a February thaw are the tell.
- Balloon-framed walls and open chases in the historic blocks off Michigan Ave and around downtown
- Settled builder-grade blown-in in 1990s–2000s subdivisions south of town
- Bonus rooms and knee walls that bake in July and freeze in January
- Ductwork in vented attics losing conditioned air before it reaches the rooms
- Uninsulated rim joists and crawl spaces in the rural properties out Lodi and York Township way
The Attic Insulation Process We Follow in Saline
Homeowners comparing attic insulation installers in Saline usually want to know what actually happens on the day. Here is our order of work:
- Inspect and measure. Existing depth, moisture staining, soffit-vent condition, bath fans venting where they should.
- Protect the house. Runners and plastic from the door to the attic access.
- Air seal the ceiling plane. Two-part foam on top plates, penetrations, dropped soffits, flue chases with fire-rated detailing, and the hatch itself — this step is what stops the stack effect.
- Baffle the eaves so soffit intake stays open under the new depth.
- Insulate. Blown-in fiberglass to R-49 over the sealed ceiling, or closed-cell spray foam at the roof deck when the attic holds ductwork or can’t be vented.
- Document. Depth markers, photos, and the paperwork for the 25C federal credit — 30% of qualifying work up to $1,200 a year.

Basements & CrawlsSaline Attic Insulation Questions
How does the attic insulation process work in a Saline home?
We start with an inspection in the attic itself — measuring what is there now, checking ventilation and moisture. Then we air seal the ceiling plane before any insulation goes in: top plates, wiring and plumbing penetrations, dropped soffits, chases and the hatch. Only after the sealing do we insulate, either blown-in fiberglass over the attic floor or closed-cell foam at the roof deck. Most Saline attics are a one-day job.
Do you install blown-in attic insulation in Saline, or only spray foam?
Both, and for the majority of vented Saline attics the best-value answer is air sealing plus blown-in insulation to R-49. Foam at the roof deck earns its premium when the attic contains ductwork or an air handler, or when a cathedral ceiling or finished bonus room can’t be vented properly.
What do attic insulation installers charge in Saline, and is there a tax credit?
We price after we look — square footage, existing depth, how much air sealing the ceiling needs, knee walls and dormers. The estimate is free and itemized. Qualifying insulation and air-sealing work earns the federal 25C credit — 30% of the job up to $1,200 per year — and we hand you the paperwork for it.
