What an absolute pleasure to deal with Arena Windows. We had a major problem with the very old patio doors in our Liverpool property. Suffice to say, we contacted Arena explained the position that we needed/wanted new French Doors installed in days (May 2016) rather than weeks. They rose to the challenge like Gladiators! New Doors installed in ONE week. Workman where excellent, with no mess for me to clean up. Not forgetting the office staff who where also always polite and courteous. Would I recommend and use them again You BET! Thanks Arena!
