About Harper Construction

As a mid-size Southern Ontario-based company, Harper Construction has built upon the principles of honesty and integrity. Our family-owned and -operated company has strived to deliver quality construction with exceptional customer service for over 50 years. We have been helping the residential, commercial, industrial, institutional, and retail customers with new builds, renovations and custom design-builds. Our commitment to excellent workmanship, client satisfaction and timely deliveries within budget have been some of the contributing factors towards our success.

Through the years, we have built a strong reputation and lasting relationships with our clients and sub-contractors. From cost estimating to giving the final touches, we understand the importance of completing a project on time, with precision and at a quality that our founder, Jack Harper, would be proud of.
