Sewer gas smell in house — Madrid, Madrid
A rotten-egg or sulfur smell inside your home usually means sewer gas is escaping through a dried-out trap, cracked drain pipe, or failing wax ring on a toilet. Sewer gas contains methane and hydrogen sulfide, which are unpleasant and potentially hazardous in high concentrations. A licensed plumber can locate the source, restore trap seals, replace damaged components, and ensure your venting system is working properly.
Waarom dit veel voorkomt 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.
