Window fogging between panes — Barcelona, Catalonia
Condensation or a milky haze trapped between the two panes of a double- or triple-glazed window means the insulating seal has failed. Once the seal breaks, argon or krypton gas escapes and moisture-laden air enters the gap, reducing the window's insulating value by up to 50%. The foggy appearance worsens with temperature swings and humidity changes. In some cases the glass can be replaced without removing the frame (an IGU swap), but older or specialty windows may require full replacement. A handyman or window specialist can evaluate whether a defogging service, glass-only replacement, or full window swap is the most cost-effective fix.
Waarom dit veel voorkomt in Barcelona
Barcelona's large stock of early-1900s and pre-1980 apartments generates steady demand for tile repair, damp-proofing, and fixture replacement, often complicated by heritage constraints and shared-building rules. The active renovation market in Gràcia, Sant Antoni, and the upper Eixample sustains handyman demand year-round.
