Attic Insulation Replacement & Air Duct Work in San Rafael, CA

Completed project · San Rafael, CA 94903 · March 2026

No removal was needed here. Photos from this San Rafael attic show the floor open between the joists, so the job was a straight install: new R-38 16in fiberglass batts across 1,360 sq ft, with the air ducts removed and replaced to code at their existing diameters.

The challenge

An attic floor open between the joists

Before the work, the photos show the ceiling boards exposed between the joists across the attic floor, with wiring running over them and an old duct run crossing the space.

Because nothing had to come out first, the scope stayed focused: protect the home at the access point, replace the air ducts, and lay a full new layer of R-38 over the 1,360 sq ft.

The service

What the crew did, in order

Prep and protection

Floor protection and dust barriers set at the access point before any material was moved, so the rest of the house stayed clean.

Air duct replacement

Air ducts removed and replaced to code, matching the existing diameters.

New insulation

New R-38 16in Fiberglass Batts installed across 1,360 sq ft.

The result

1,360 sq ft of new R-38, and new air ducts

Floor protection went down at the access point. Air ducts were removed and replaced to code, matching the existing diameters, and new R-38 16in fiberglass batts were installed across the full 1,360 sq ft of attic floor.
