Interior Renovation For Second Unit

General Contractors review in Toronto



Permit Works exceeded our expectations. Every person we talked to, the architect Kelvin, the accountant Salik, the designer Eliza, the engineer, the whole team, was knowledgeable, patient, polite and friendly. They helped us understand the process, answered all of our many questions, accommodated our ideas and submitted detailed drawings and a highly professional building permit request to the City. We were so happy when the Permit to Construct was issued within 2-3 days. So many thanks for all of your help and outstanding work!

This was my very first permit-required project and couldn't have done with Permit Works! From the site visit, design to permit application, these guys were professional, thorough, and friendly answering all my questions promptly. Will definitely reach out to them on my next project.
