Very fast and efficient! Will definitely use them again. Aru came down for a site visit, and upon some quick inspection, told me i can use back the old acrylic board for the new kdk fan , although the previous fan was from a different brand. Helped me saved a lot of money. He came down the next day and helped me fixed the new kdk fan in a jiffy. Very impressed with his efficiency and professionalism.

Everyworks Aru explained clearly what is required to fix a new ventilation fan for my toilets . He measured them correctly and Everyworks gave me the best price out of three other contractors that I surveyed . They gave me a fast appointment and sent their employee Aru to measure free of charge . Panels were well fitting and the ventilation fans works wonderfully . Aru made sure to show me how it works and tested both units before he left . He even asked for a broom and cleaned up the area for us . Truly value for money with efficient service . Most of all I loved that Everyworks allowed me to buy my own appliance and did not force me to buy their unit for the installation service . Hence I was able to complete the work within my budget . This is my 3rd time engaging their service and truly satisfied 😊
