Energy Audits for Portsmouth's Older Homes
Portsmouth has some of the oldest housing stock in New England. Colonial and Federal homes in the South End and around Strawbery Banke, Victorian and early twentieth century houses in the West End and Christian Shore, and mid-century capes and ranches across town were all built long before modern insulation and air sealing. Many have balloon-framed walls with open cavities, uninsulated or lightly insulated attics, fieldstone or brick foundations, and decades of add-ons and renovations. Together those add up to drafts, cold rooms, ice dams and high heating bills.
A home energy audit shows where your house is actually losing heat so you can fix the problems that matter most, without guessing and without tearing into historic plaster and trim unless you need to.
What's Included
Every audit includes a blower door test to measure how leaky the house is and locate the drafts, an infrared camera inspection to find missing insulation and hidden air leaks, and combustion safety testing to make sure your heating equipment is running safely. Homes with forced-air systems can add duct leakage testing. Afterward you get a written report with costs, estimated savings and prioritized improvements. Read more about our home energy audits.
