Largo Green (LG) solved a problem 3 other contractors could not. Client's nightmare was a reoccurring bedroom ceiling leak that was a nuisance for years. LG found 4th floor slate hadn't been installed nor sealed properly. LG removed the old mortar & cement sub flooring, rebuilt balcony corner at leak origination, & added thick moisture barrier. LG installed new tiles & flashing, then sealed it all with the strongest lacquer available.
