"I could not be happier with the new windows. Kayleigh was friendly and very understanding of my requirements. The cost was less than I had anticipated. Kristian was spot on with measurements and very helpful advice and Will and Kristian fitted the new windows quickly and efficiently and left my flat spotless. I recommend KMC Windows without hesitation."

"Excellent job, from initial consultation by Kristian and communication throughout with Claire in the office. Thank you also for such a smooth experience this time, we're really pleased with the replacement roof, it looks brilliant....so much lighter!! Also, really appreciate how hard Brendan, Andy and Will worked to get the job finished in two days...it all went like clockwork!! Would recommend this company without hesitation....."

"Would not hesitate to recommend KMC . From the initial quote all the way through they were professional. The quote for the work was good and the fitters excellent They were polite , friendly , very tidy and quality of workmanship great . Cannot fault this company at all. Looking forward to having them back later in the year to do a patio door for us."
