About Us


Carlos D. Guerra was raised in a business-oriented family and started working from a very early age. When he was 23-year-old, he opened his first business, a hardware store, which was his first step to build his construction company. During this stage of life, he got his bachelor’s degree in Economics.

In addition to being a young businessman, he got his first job as a part-time professor at The Autonoma University and Littoral University in Colombia while he continued managing his business.

The political circumstances in Colombia led him to leave the country and settle in New York where he opened a travel agency where he worked for 7 years. After that, an opportunity to return to his country arose as he started a new venture that engaged in importing electric materials from China. The political situation had not changed much, therefore he decided to immigrate to Canada in 2005.

In Canada, while keeping an open mind, he tried different options and held various positions. In 2009, he started working as a part time contractor while working in sales but always thinking of starting his own business. Eventually in 2012, Carlos decided to venture out and started his Davinci Contractors Company. He started working full time doing painting and renovations.

Penetrating in such a competitive market was not easy but Davinci Contractors earned a place in the industry by always working with high standards of quality, remarkable customer service and by applying all the networking experience that Carlos had acquired over the last 40 years. In 2020, Davinci Contractors was recognized and awarded the Best Business of 2020 Excellence Award by ThreeBestRated as one the best companies in paint and renovation in London Ontario.
