100% happy with K&K windows from start to finish. Everyone I dealt with throughout the process were professional, helpful and friendly. Jimmy gave us the initial quote and was a pleasure to deal with. Everything from then on was smooth and reliable. The lads that fitted were so clean and respectful of my home. And the girls in the office were friendly and helpful, and i am very very pleased with my windows and door. I would have no hesitation in recommending K&K windows.
