Fantastic Job
Customer Service
We really couldn't fault KJN. They were reliable, trustworthy and honest. Their standard of work was very high and timekeeping and cleanliness were impeccable. We had a large kitchen extension and other innovation work carried out and were extremely pleased.

KJN fitted a new front door for me about four months ago, I am really happy, over the moon! His team did a fantastic job and I would absolutely recommend them without a doubt.

Spot on
Customer Service
I had all my windows replaced last Summer, the work carried out was fine, spot on, no complaints. I highly recommend them, and I'm planning on using them again for my extension. They are very professional, polite and particular.

Excellent product and excellent service
Customer Service
KJN supplied and installed a sliding patio door and a set of French windows. I not only very pleased with the VEKA product but also with the service. KJN did an excellent job of fitting the doors.
