Four services. One standard.
Every project we take on is built to the same performance standard — whether it’s a new 5,000 sqft custom home or a 400 sqft envelope retrofit on an ADU.
Custom High-Efficiency Homes
Ground-up custom homes built to a measurable performance standard. 2,500–6,500 sqft typical, every home blower-door tested and balanced-ventilated.
- Manual J/S/D load calculation
- Full envelope and mechanical spec
- Pre-drywall and final blower door tests
- Balanced HRV/ERV with MERV 13+ filtration
- Continuous exterior insulation
Full Home Remodels
Whole-home gut and re-envelope — the right way to bring a 1990s or 2000s house to a 2026 performance standard.
- Existing-conditions assessment
- Re-framing and structural upgrades where needed
- New WRB, flashing, and rain screen
- Insulation, air sealing, and mechanical refresh
- Window and door replacement
ADUs + Guest Houses
Accessory dwelling units built to the same building-science standard as the main house — no shortcuts, no "ADU-grade" finishes.
- Site planning and code review
- Detached and attached configurations
- Right-sized HVAC and water heating
- Same envelope detailing as main house
- Independent metering where applicable
Additions + Envelope Upgrades
Targeted retrofits and additions that measurably improve existing homes — sometimes just a wing, sometimes a re-skin of the whole envelope.
- Existing assembly diagnosis
- Air sealing and insulation upgrades
- New high-performance windows
- HVAC right-sizing or replacement
- Optional blower door verification
