Basement cold and drafty — Haarlem, North Holland
A basement that stays noticeably colder than the rest of the house or has persistent drafts usually points to insulation gaps, air leaks around the rim joist, unsealed foundation cracks, or inadequate HVAC duct coverage. An HVAC technician can assess duct routing and airflow, while a handyman or insulation contractor can seal air leaks and add insulation.
Why this is common in Haarlem
The damp maritime climate makes mold control a priority, and the gas-to-heat-pump transition is complicated in the protected centre where monument rules limit visible exterior plant. Coastal humidity adds to climate-control demand.
