Gas smell in the house — Alkmaar, North Holland
A natural-gas or rotten-egg smell indoors is a potential emergency. Natural gas is odorless by itself — utilities add mercaptan so leaks are detectable. Even a faint whiff can indicate a cracked gas line, a faulty appliance connection, or a failing gas valve. Leave the house immediately without flipping switches or lighting flames, call your gas utility's emergency line from outside, and then contact a licensed plumber or HVAC technician for the repair.
Why this is common in Alkmaar
Alkmaar's historic canal ring is built on wooden pile foundations in waterlogged soil, creating the same drainage and leak challenges as Amsterdam canal houses but on a smaller scale. Lead water supply pipes remain in a significant proportion of pre-1970 homes, and the hard North Holland groundwater causes heavy limescale buildup in boilers and tap fittings.
