TL;DR
A Family Handyman winterization report recommends checking insulation and air leaks in 10 areas, including attics, exterior walls, windows, pipes and HVAC ducts. Contractors cited in the report say the work can help reduce heat loss and protect pipes, though results and costs depend on each home.
Family Handyman has published a 10-point winterization checklist advising homeowners to inspect insulation and air leaks before cold weather arrives. The report, citing roofing and HVAC contractors, prioritizes attic and roof spaces and also covers walls, windows and doors, plumbing, basements, garages, ductwork and small openings around outlets and utility lines.

Andre Kazimierski of HomeHero Roofing told the publication that air sealing and insulation address different routes of heat loss: sealing gaps limits drafts, while insulation slows heat moving through building materials. He recommends checking aging roofs for openings that can let cold air into the attic and then into the home. The report also advises insulating the attic floor, commonly with fiberglass batts or blown-in material, to separate a vented attic from living areas.
For finished exterior walls, contractor Bob Cardwell of Cardwell HVAC said blown-in insulation can be added without opening the walls, while spray foam can seal gaps. The checklist recommends checking window and exterior-door seals and weatherstripping, and adding door sweeps where needed. For plumbing, it focuses on pipes near exterior walls or in unheated spaces such as attics, basements and crawl spaces; foam sleeves may suit exposed pipes in somewhat protected areas, while heat cables are suggested where temperatures regularly fall below 32 degrees Fahrenheit.
Other areas include basement rim joists and foundation penetrations, shared walls between a garage and the home, and exposed HVAC ducts in attics, crawl spaces or basements. Cardwell recommends closed-cell foam for some damp basement gaps and mastic or UL-listed foil tape for duct leaks. The report says ordinary duct tape is not suitable for HVAC ducts. It also recommends foam gaskets at electrical outlets and caulk or spray foam around small pipe and wire openings.
Where Heat Loss Can Add Up
The checklist focuses on both comfort and household systems. The report says insulation can help limit heat escaping from living spaces, protect vulnerable water pipes from freezing and reduce demands on heating equipment. Those are potential benefits, not a guarantee of a particular reduction in energy bills: the report provides no measured savings, project costs or estimates for individual homes.
Its emphasis on small leaks reflects the contractors’ point that insulation alone may leave drafts unresolved. Homeowners can use the locations listed to guide a fall inspection, then decide whether a repair is manageable or needs a professional assessment.

Why Attics Lead the Checklist
The report places attics and roof spaces first because warm air rises and gaps around an aging roof can admit cold air. It quotes roofer Cody Purtle of Silver Ridge Roofing saying inadequate attic insulation can allow significant heat to escape through the roof. The checklist recommends checking attic insulation and drafts, while recognizing that many attics need ventilation and should be thermally separated from the rooms below.
Not every area needs the same treatment. The report says homeowners do not need to insulate every water pipe, and that a garage generally need not be fully insulated unless it shares a wall with the house or is used as living or work space. Its recommendations are a general checklist; the right material and scope depend on the home and conditions.
“Sealing gaps goes a very long way with improving overall insulation.”
— Andre Kazimierski, HomeHero Roofing
Costs and Home Conditions Vary
The report does not provide project costs, energy-savings figures or a publication date, and it does not establish that every home needs all 10 interventions. The extent of heat loss and the suitable repair depend on the building, existing insulation, moisture conditions and local climate. The source excerpt also ends midway through a discussion of when to add attic insulation, so it does not supply the full seasonal recommendation attributed to Cardwell.
Inspect and Prioritize Repairs
Homeowners can begin with a fall check of the attic, roof, exterior-door and window seals, pipes in unheated areas, and accessible ductwork. The report advises contacting a roofer to inspect and seal roof gaps, particularly on an old or weathered roof. After identifying drafts or missing insulation, homeowners can determine which repairs fit the conditions and seek contractor advice for larger or less accessible jobs.
Key Questions
Which area should homeowners check first?
The report puts attic and roof spaces first, citing rising warm air and the possibility that roof gaps let cold air reach the attic and home.
Do all water pipes need insulation?
No. The checklist focuses on pipes near exterior walls and those in unheated areas such as attics, basements and crawl spaces. It also recommends insulating hot-water pipes to limit heat loss.
What can seal leaks in HVAC ducts?
Cardwell recommends mastic or UL-listed foil tape for leaks at duct joints and seams. The report says ordinary duct tape can dry out and does not work well on HVAC ducts.
Does the report estimate energy-bill savings?
No. It says insulation and air sealing may help limit heat loss and HVAC demand, but gives no savings estimate or measured results.
