This video covers many of these subjects, Including: inspection checklist, activate temporary electric pole, proper scheduling, vapor drive/diffusion defined and code differences in regions.

    Roof

  • Proper sizing
  • Dampers
  • Outside air intake
  • Humidifiers
    Plumbing
  • Proper PVC and copper install
  • Sealing/flashing wall and roof penetrations
  • Sump pumps
    Ventilation
  • Bath fans
  • Range hoods
  • Dryer vents
  • Gas fireplaces

  • Insulation
    How insulation is installed and detailed also impacts the management of moisture in a new home. A number of issues must be properly addressed, as in this video and: Kraft faced insulation, insulate behind tub/shower units, proper sealing of penetration, caulking and seal where you see light.

    Exterior Cladding
    Like the roof, the walls and their exterior finish must be properly detailed to shed a tremendous amount of direct, run-off and wind-blown rainfall. In order to properly handle that water, care must be taken with the following details;
    Siding
  • Wood (Vinyl/Aluminum Siding, Hang Siding, Proper J channel/starter & strip installation)
  • Cement Board
    Brick
  • Head and bed joints
  • Maintaining a clean air space
  • Weep holes
    Lightweight Stone
  • Double layer weather membrane
  • Scratch coat
  • Proper door and window flashing

  • Flashing and Runoff Controls
    Finally, dealing with the holes in the various building elements and how we direct water away from them and the main building elements is critical to moving the water out. In this video we take a look at a number of these issues, including: window and door flashing/sealing, review all roof and wall penetrations, proper gutter and downspout sizing and installation, splash blocks and final grade details.
