4EverGreen Energy Auditing, in conjunction with Clarus Building Inspections, provides professional home, commercial and energy efficiency inspections throughout the greater Northwest Washington area.

Over the years, Clarus Building Inspections, (a subsidiary of 4EverGreen Energy) has inspected hundreds of older and newer homes in the greater Northwest Washington area. With energy prices soaring and tax rebates offered for energy efficiency upgrades for pre-existing homes, it's no wonder we are often asked by our clients what they can do to make their homes more comfortable and energy efficient. We advise them to start with a home energy audit (also referred to as a home energy inspection or home performance assessment).

While many things contribute to energy waste in the average home, air leakage in the building shell and leaky ductwork pose some of the greatest concerns. Some studies indicate that the average home loses 30% or more of its heat through leaky ductwork alone. During our inspections, we have actually seen many ducts completely disconnected from their intended heat registers and blowing into attics and crawlspaces. It's easy to see how the most efficient heating systems can be undermined by unsealed leaks.
