Professional, fast, and affordable

Lekesh came over and helped to check and confirm whether or not two walls in my home were structural. He then provided recommendations on removal and reinforcement, and finalized everything in a written, stamped report. He was easy to work with and completed his work in a timely manner. Thanks for your help!

Ultimately we got hassle free approvals for the design and minor variance applications despite the odds being against us

We consulted with Quintic Engineering for a second dwelling unit design and renovation project and couldn't be happier. It wasn’t an easy project, but they worked with us through various design iterations as part of the planning. Ultimately we got hassle free approvals for the design and minor variance applications despite the odds being against us - thank you and Keep up the good work..!

Lekesh from Quintic did a very exceptional job by providing duct layout as required

I am an experienced contractor working in the industry from last ten years, we hired Quintic Engineering Inc. for a Mechanical design project in City of Mississauga. It was addition to the existing house and the project required calculations of the new Heat Loss and Heat Gain, Duct design, Ventilation design and Energy Efficiency design summary. Lekesh from Quintic did a very exceptional job by providing duct layout as required by us around the house avoiding any low spots in the middle and saved tons of money for the client by proposing the existing furnace being capable of supplying the added volume of new addition to the house. Quintic team was quick in design preparation and answering any city comments or issues during construction. I am very pleased with the professional service received. This was my first time working with them but definitely not the last and would recommend to others.
