Gas smell in the house — Madrid, Madrid
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 Madrid
Madrid's dense pre-1980 apartment blocks across Tetuán, Carabanchel, and the Ensanche carry ageing galvanised and cast-iron plumbing prone to corrosion and blockage. The continental climate adds a winter freeze risk rare on the coast — exposed pipes, rooftop deposits, and unheated patios can freeze in cold snaps, making burst-pipe emergencies a genuine winter hazard alongside the usual hard-water limescale.
