Recent Attic Restoration Work in Ballard
Attic Cleanout, Full-Perimeter Rodent Proofing, Air Sealing & New Insulation
Attic Doctor completed a two-day attic restoration project at an older residential home in Ballard in June 2026. Years of rodent activity had contaminated and damaged the attic insulation, and the age of the home left numerous openings around the roofline and attic perimeter. The team removed the affected insulation, completed extensive rodent proofing and air sealing, and installed new insulation to create a cleaner, more efficient, and better-sealed attic.

2-Day Project
Four crew members day one, two on day two
Full Perimeter Sealing
Extensive rodent entry points addressed
Steel Mesh & Foam
Quarter-inch mesh reinforced with sealant foam
Scope
- Remove rodent-contaminated attic insulation
- Clean out the attic to expose the full perimeter
- Inspect the roofline and plywood edges for entry points
- Rodent-proof the entire attic perimeter
- Install quarter-inch steel mesh wire over openings
- Staple mesh securely into place
- Use gap-sealant foam to reinforce and hold the mesh
- Complete attic air sealing
- Install new batt insulation
- Work through a small attic access opening
- Pass insulation pieces through the access one at a time
Outcome
- Years of rodent-damaged insulation were removed
- Previously hidden perimeter openings became visible after cleanout
- Extensive rodent entry points were sealed throughout the attic
- Steel mesh and foam created a reinforced perimeter barrier
- Air leakage pathways were addressed during the restoration
- New insulation improved the attic's thermal efficiency
- The appearance of the attic was completely transformed
- The project was completed over two working days
- Photos allowed the homeowner to see the completed improvements
- The homeowner was very satisfied with the finished work
Key Takeaway
Older homes can require significantly more rodent proofing than newer attic spaces. Once the contaminated insulation was removed from this Ballard attic, the team could see daylight entering around much of the perimeter, revealing how many openings had developed over time. Attic Doctor used quarter-inch steel mesh secured with staples and reinforced with gap-sealant foam to close those vulnerable areas before air sealing and installing new insulation. Despite tight working conditions and a very small attic access, the team completed the restoration in two days and left the homeowner with a cleaner, more efficient attic designed to keep rodents from returning.
Recent Crawl Space Work in Ballard
Follow-Up Crawl Space Clean-Out, Rodent Proofing & Moisture Barrier Highlight
Attic Doctor returned to a residential home in Ballard for the second phase of a rodent-proofing project after completing attic clean-out and rodent-proofing work the previous Friday. When rodents appeared in the client’s kitchen over the weekend, the team responded quickly the following Monday to clean out the crawl space, continue rodent proofing, re-insulate, air seal, and install a moisture barrier.

Fast Follow-Up
Returned quickly after kitchen rodent activity
Scope
- Clean out the crawl space
- Continue heavy rodent proofing throughout the crawl space
- Seal entry points with mesh wire and foam
- Re-insulate and air seal the crawl space
- Install a new moisture barrier
Outcome
- Extensive rodent activity was identified, including dead rodents, tunnels, and damaged insulation
- The team barricaded the crawl space interior as thoroughly as possible
- Entry points were sealed from both inside the crawl space and visible exterior areas
- Traps were placed in the crawl space, attic, and kitchen areas where rodents had been seen
- The client was happy with the quick response and how clean the crawl space looked afterward
Key Takeaway
Rodent-proofing older Seattle homes requires persistence, especially when activity is coming from the crawl space into the first floor. In this Ballard follow-up project, Attic Doctor responded quickly after the client saw rodents in the kitchen, then dedicated the time needed to clean out the small crawl space, seal as many entry points as possible, re-insulate, air seal, install a moisture barrier, and place traps where rodent activity had been reported.
Recent Attic Work in Seattle
Attic Restoration, Rodent Cleanup & Re-Installation Highlight
Attic Doctor completed a residential attic restoration project in Seattle involving full attic cleaning, rodent-related restoration, and re-installation. The main issue was rodent activity in the attic, and the work followed a straightforward restoration process focused on containment, cleanup, and careful execution.

Key Takeaway
Even when a project is straightforward, good attic restoration still depends on proper prep, careful containment, and attention to detail. In this Seattle project, a focused four-person crew completed a full attic restoration and re-installation after rodent activity had compromised the space.
