The presence of water in the home can have a negative impact on the health of occupants and durability of materials. It can be a challenge to identify the cause. Using the principles of building science, an energy consultant can solve water issues that cause problems such as condensation and mold to appear on windows, walls, and baseboards. An energy audit with a focus on a water inspection will look at all of the ways water can accumulate in a building and use diagnostic tools to evaluate and solve the problem.
