The Adkins Coastal Retrofit & Thermal Envelope Overhaul

A complete 3-story coastal residential transformation: failing T1-11 plywood replaced with modern weather-tight blue-gray siding, 5/4x6 architectural trim, new view windows, and enclosed deck soffits.

Location Kenai Peninsula, AK
Square Footage 2,650 sq ft
Duration 3 Months
Budget Range $160,000 – $220,000
The Adkins Coastal Retrofit & Thermal Envelope Overhaul

Owner's Goal & Vision

Transform an aging, weathered 3-story coastal residence with deteriorated T1-11 plywood siding into a fully weather-tight, energy-efficient modern home with panoramic inlet views, new architectural trim, and finished balcony soffits.

Construction Challenges & Solutions

Challenge 1

Remediating severe coastal wind-driven moisture penetration behind deteriorated exterior siding and unsealed rough openings.

Challenge 2

Framing and weather-sealing a new 3rd-floor picture window into an existing load-bearing exterior shear wall.

Challenge 3

Converting an unfinished second-floor exterior patch into a fully flashing-integrated exterior access entryway.

Challenge 4

Enclosing raw rafter tails and balcony decking soffits to eliminate moisture collection and sub-zero air infiltration.

Materials & Mechanical Systems Used

  • ✓ High-performance Tyvek CommercialWrap vapor-permeable air barrier with sealed seam tape.
  • ✓ Durable engineered composite siding finished in custom coastal blue-gray with stainless ring-shank nails.
  • ✓ Architectural 5/4x6 primed cedar window casing, wide corner trim, and horizontal dividing belly bands.
  • ✓ Triple-glazed Argon-filled picture window packages engineered for coastal wind shear and thermal performance.
  • ✓ Enclosed vented soffits with hidden continuous insect screening.

Cold-Climate Sub-Zero Considerations

  • • Dual-layer self-adhering ice and moisture barrier around all rough window and door openings.
  • • Engineered drip caps with kick-out flashing at all roof-to-wall and belly-band intersections.
  • • Continuous perimeter skirting preventing cold air freeze-up under cantilevered floor assemblies.
