Highlights

"Everything went as planned with no hiccups. Finished the work before christmas as promised. Had a small problem with new bifold door and they sorted it out same day. Anestis and his team have were all excellent."

"Excellent service consistently throughout the entire month. Immaculate finish to the house, contractor and company went above and beyond to ensure all areas of the house was finished to its utmost quality. Even small details were taken care of. We were informed about all relevant details, and updated whenever something was completed. There were no delays. Work was fast, reliable and perfect."

"The team at KO Marko building were great from start to finish. No job was too much trouble, even if this was additional to what was agreed originally. We had a new kitchen fitted, new bathroom, installation of a downstairs toilet and removal of an internal wall. KO Marko building contractors completed all the work very quickly and to a high standard. Very pleased with the final outcome! They transformed a dated house to a modern and bright home!"
