Exterior

A typical tour of a house that our highly experienced inspectors would take prior to giving the homeowner an estimate or recommendation include:

  • Exterior inspection:

    • Measure exterior wall area

    • Determine exterior wall materials - heat absorption and radiation into the house varies:

      • Aluminum siding would radiate more heat than oak shingles

      • Dark colors absorbs more heat while light colors reflects heat

    • Our exterior inspection checks for window size and construction, wall insulation values, and moisture retention, among many other factors.Our exterior inspection checks for window size and construction, wall insulation values, and moisture retention, among many other factors.

      • Measure window area

      • Determine window construction:

        • Single, double or triple-pane

        • Insulated, tinted, coated with UV protection

        • Are the windows old or new? Newer windows can incorporate new technology to help reduce heat loss

        • Are the frames plastic, aluminum, wood? Aluminum frames can cause a great deal of heat loss, while wooden frames help prevent it.

        • Are there any skylights in the ceiling? Skylights let light, and therefore heat, enter the living areas of your home, which must be taken into consideration to accurately determine the correct system size.

        • Check insulation values:

          • Attics, basements and crawlspaces

          • Is attic insulated?

            • Without proper ventilation an uninsulated attic can become an oven in the summertime, which can add a lot of radiant heat to the lower levels of the house.

            • A properly ventilated attic can save as much as a ton of overall cooling capacity.

        • Moisture retention – Is water being retained in the crawlspaces under the home? This can cause excess humidity to enter the house and may require the installation of a sump pump to correct the problem.

        • House orientation – we are one of the few companies that actually brings a compass to the site to determine orientation, the direction the home faces in relation to the sun.

          • This is an important factor as, in the northern hemisphere, a home with southern exposure receives much
            more sunlight (therefore more heat) during the day, which might require less heating, but more cooling capacity
            in the summer months.

          • Conversely, a home with northern exposure may be susceptible to heat loss from cold northerly winds in
            the winter.

      After the tour is completed, our inspector will present his recommendations to the homeowner.
