A Family Business Built to Last

Costa Caulking was founded more than 50 years ago by Vitalino Costa. What began with one tradesman’s commitment to honest service and quality workmanship grew into a trusted name in the caulking industry.

Today, Costa Caulking is led by David Costa, President and the public face of the company. David works closely with customers and leads the team with the same commitment to quality, service and dependable workmanship established by his father.

Supported by Kevin and an experienced team, David continues to carry the family business forward while serving residential and commercial clients throughout Toronto and the GTA.
