"I have used KCJ for 18 years and he and his team are amazing! Professional, courteous, hard-working - ready to rectify the odd minor error if it ever occurs (rarely). I trust Peter, the owner, and so do all my tenants as we are abroad for my husband's work. He knows them by name, helps whenever an issue arises. Honest. Reliable."

CHRISTIAN L / NW5 / JUN 2024
"I have used KCJ a number of times over the past few years. I have always found Peter, the boss, to be helpful, patient and happy to give me suggestions. This time i also liaised with his colleague Nadia who was the same and a pleasure to talk to. The workers were consistently friendly, polite and punctual. The work was of a high standard and when i changed my mind about what i wanted this was accommodated without complaint. I found their price to be reasonable. I have recommended them to friends and colleagues."
