Guarantees for windows and doors

Windows and doors are a long-term investment that directly affects the energy efficiency, security and comfort of your property. That is why Extol guarantees the quality of every component — from profiles and glass to hardware and installation.

Unlike imported products without a local service network, Extol has its own production facilities and certified installers in the field. If you make a guarantee claim, you will not wait weeks for a response — our service team responds within two business days.

We use only certified profiles and hardware from leading European manufacturers — TROCAL, ROTO and WINKHAUS — which meet strict EU standards for thermal insulation and mechanical strength.
