- Replacing windows, doors or ductwork, and HVAC repair or replacement.

Before you book weatherization & air sealing package
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Map your drafts before the visit
On a windy day, note rooms with cold spots, drafts at outlets and doors and floors that feel cold. Those notes help the pro start where it matters.
Clear access to attic and crawlspace
Move stored items away from the attic hatch, the rim joist and the crawlspace door. Clear access shortens the visit and lets the pro seal what they find.
Tell the pro about fuel appliances
Gas furnaces, water heaters, wood stoves and fireplaces need a safety check after sealing. Mention what you have so the test is planned.
Photograph problem areas
Pictures of frost, stains, gaps at doors or an old attic hatch show the pro what to prioritize before arriving.
Ask whether an audit comes first
Find out if a blower door test is included, and if a full energy audit is a separate step. An audit can set priorities for sealing, insulation and equipment.
Ask for a before and after reading
A pair of test numbers is the best proof the work did something. Ask the pro how the results will be shown, and what they will tell you if the number barely changes.
