About the House

2,460 sf
Basement - Rubble Foundation Wall and
Crawlspace with Dirt Floor
Walk-up Attic
​Oil Boiler - Hot Water, Cast Iron Radiators

Walk up Attic

Crawlspace - Basement

Exterior Walls

Findings and Recommendations

• Timber frame structure - movement
• Knob & Tube wiring
• Bulk moisture - dirt floor in crawlspace, water seepage in basement, no bath fans
• Little to no insulation in attic, basement-crawlspace, exterior walls,
• LOTS of air leakage

​Master Plan - Holistic and Phased Approach

Phase 1a– Address Safety and Structure

• Remove knob & tube wiring
• Perform structural repairs
• Remove ventless heating appliance
• Mitigate bulk moisture

Phase 1b – Address Insulation

• Air seal & insulate attic
• Air seal & insulate crawlspace
  
  

Future Phases
Fine-Tune Boiler Operation:

• Replace older supply/return piping​
• Additional zones for comfort

Sill Repair​:

• Air Seal-Insulate Sill
• Insulate Foundation Walls

Insulate Exterior Walls:

• Includes drilling, filling and patching
