 The quality of the blocks of flats also left much to be desired, with numerous complaints about flooded cellars and faulty heaters (which had to be replaced in more than 400 buildings) prompting the local authorities to undertake a massive program of repairs.Because of this situation the word ‘Retkinia’ accreted negative associations and was sometimes used in the 1980s as a generic term for an unwelcoming and ugly block housing estate.High-pressure gas installation in Retkinia proved to be dangerous, and in 1982 there was a gas explosion that led to two deaths.
