Whilst I was a little daunted once I'd made the decision to have all the windows and doors replaced KLG made the whole experience seamless. From Marc, who was extremely patient and helpful whilst I was asking questions and choosing which product to the installation by Eddie and Aaron. Great guys who managed to installed 2 lintels, 11 windows and 2 doors in just over 2 days and during storm Eunice. Never known guys to work so hard. Quality of doors, windows and installation great and they were extreamley tidy and respectful. Would definitely recommend this company.
