Attic air leaks: the top offender
Almost every audit finds the same thing first. The attic floor leaks like a sieve. Top plates, wire holes, pipe chases, the hatch. Sealing them is usually the highest-impact fix in the house.
Thin attic insulation
Second on the list. Most attics sit far below the suggested depth. The fix is simple and the payoff is fast.
Leaky ducts
Ducts in attics and crawls leak at the joints. Some lose a fifth of their air before it reaches a room. Sealing ducts is unglamorous and effective.
Missing wall insulation
The infrared camera finds cold walls where insulation was skipped or settled. Older homes are the usual suspects. Fixing walls costs more than attics, so it ranks lower per dollar.
Poor ventilation
Blocked soffits, missing ridge vents, bath fans dumping into the attic. Vent issues cause moisture trouble that ruins insulation. Audits catch them.
What audits rarely find
Bad windows are rarely the top issue, despite the ads. Old windows lose less than a leaky attic. The audit proves it with numbers, which saves you from a costly wrong fix.
The ranked list
The real value of an audit is the order. You get the fixes ranked by impact per dollar. Do the top three and most homes feel transformed. The rest can wait.
