Weatherstrip a Katahdin Avenue duplex in Millinocket (2026-07-20)

A duplex on Katahdin Avenue, built for Great Northern Paper mill workers, has original 1930s window and door seals that have failed, and winter heating costs are pushing the household budget hard. The resident needs a full weatherstripping pass before the cold sets in. Standard: Efficiency Maine / NEEP cold-climate weatherization guidance Proof: Before and after photos of every sealed opening plus a GPS-tagged confirmation of the address. Method (Efficiency Maine / NEEP cold-climate weatherization guidance): 1. Walk the home with the resident and mark every door and window with a visible draft. 2. Measure and cut new weatherstripping or a door sweep for each marked opening. 3. Strip off the old, failed material and clean the frame surface. 4. Install the new seal and fasten it along the full length of the opening. 5. Recheck each opening for daylight or draft and log the sealed count. Done when: Before and after photos of every sealed opening plus a GPS-tagged confirmation of the address.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 90–240 minutes. Method of record: Ohio Development Services Agency Home Weatherization Assistance Program (HWAP) — the state pass-through of the DOE Weatherization Assistance Program's cold-climate field protocol: blower-door-directed air sealing toward a CFM50 infiltration target, attic insulation to R-49 / wall cavity to R-13, and mandatory pre/post combustion-safety testing before any tightening closes out.

Bring

• calibrated blower-door fan + manometer
• combustion-safety analyzer (CO/ambient + spillage check)
• camera
• caulk gun + spray foam + weatherstripping
• insulation (blown-in or batt, rated to R-49 attic / R-13 wall)
• smoke pencil (leak-path tracing)
• tape measure + infrared thermometer

Steps

1. 1. Walk the home with the occupant, note every combustion appliance present, and photograph each nameplate before any work begins.
2. 2. Set up the calibrated blower door in the main entry and record the baseline CFM50 reading.
3. 3. Trace and photograph the top infiltration paths with a smoke pencil (rim joist, attic hatch, penetrations, window/door perimeters).
4. 4. Run the pre-tightening combustion-safety check (ambient CO reading, spillage test at draft hoods) with the blower door off; a failed check stops the job and routes to a licensed HVAC technician before any sealing.
5. 5. Air-seal the ranked leak paths in order and bring attic insulation to R-49 / accessible wall cavity to R-13 per the HWAP job sheet, maintaining required soffit-to-ridge ventilation.
6. 6. Re-run the blower-door test to confirm the new CFM50 result.
7. 7. Run the mandatory post-tightening combustion-safety re-test; a failed re-test stops the job and routes to a licensed HVAC technician for venting correction before further sealing.
8. 8. Photograph the finished insulation depth and the passed post-tightening combustion-safety check; enter before/after CFM50, materials used, and the combustion-safety result into the proof record; sign.

If it does not match the plan

• Pre-tightening combustion-safety check fails (elevated CO or spillage) -> STOP: do not tighten the home; route to a licensed HVAC technician before any sealing proceeds.
• Post-tightening combustion-safety re-test fails -> STOP: back off sealing and route to a licensed HVAC technician for venting correction before close-out.
• Home is pre-1978 with disturbed/peeling paint at a sealing surface -> STOP: do not scrape or sand; route to an EPA RRP lead-safe certified pro.

What counts as done

• Before and after CFM50 readings from the same calibrated blower-door setup
• Photos of each sealed leak path and the finished attic/wall insulation depth
• Post-tightening combustion-safety (CO/backdraft) check passed and logged
• Required soffit-to-ridge ventilation maintained after insulation work

Proof is measured against these, not judged by taste.
