Before weatherizing an older home: how to request a useful walkthrough

A homeowner's brief for an initial weatherization walkthrough, including comfort observations, access, priorities, boundaries and an itemized follow-up.

Document where and when the discomfort happens

Start with a simple floor plan and mark rooms that feel unusually hot, cold or drafty. Note the season, time of day and weather when the problem occurs, without claiming that these observations establish its cause. Photograph visible gaps or damaged trim from accessible positions. Record whether you have already replaced filters, adjusted doors or noticed water staining. Do not open electrical panels, remove insulation or enter unsafe crawl spaces to create a better-looking request.

Describe the building and the boundaries of access

Tell a prospective assessor whether the home is detached, a townhouse or a unit in a larger building. Provide approximate age only if known, plus information about accessible attic areas, basements and previous renovation work. If the property is rented, confirm what you may authorize before inviting work. Some rooms or storage spaces may be off-limits; mark those clearly. An assessor should be able to explain what their visit will and will not cover.

Ask about the method, not a promised savings number

Request a scope of work: visual walkthrough, discussion of comfort issues, measurements or tests if offered, and a written summary. Ask whether proposed testing carries extra charges and whether prerequisites are needed. A precise energy-savings estimate cannot be assumed from a quick consultation. If an assessor recommends major equipment replacement before documenting existing conditions, ask for the evidence and possible alternatives. Keep diagnostic services separate from later installation bids.

Watch for connected safety and moisture concerns

Air sealing and ventilation interact with building conditions, so it is unwise to seal every visible gap without considering the wider system. Report musty smells, condensation, combustion appliances and suspected leaks to the assessor. Do not ask a general helper to troubleshoot fuel-burning equipment or make undocumented electrical changes. Those issues may require appropriately qualified specialists and separate assessments. The initial conversation should identify them, not conceal them.

Turn the report into decisions

Ask for the findings in three columns: confirmed observations, suggested investigations and potential improvements. Request photos or annotated diagrams that explain the location of each recommendation. Compare quotations using the same scope, materials and finish expectations; ask who handles cleanup and what happens if hidden damage is found. Keep copies of decisions and revisit comfort observations later without inventing a guaranteed percentage reduction in bills.
