Satisfied Homeowners
"I went with Luma Design after getting quotes from several other companies. Not only was Luma’s price very competitive, but they were also the easiest to communicate with, and the job was completed on time. I’ll definitely be coming back to them for future projects."
"LUMA helped us with our Secondary Suite in Fergus Ontario. We needed additional space in our home so a home addition was the best option. LUMA's team and trades were professional and also worked with us.
Mason and Luke took time to go through options and explain why or why not to certain ideas and options. That was something as a home owner I really appreciated they talked to us normally not like we were clueless."
We had a great experience working with Mason and Luke on our renovation. They are friendly, professional, and we're completely happy with the excellent quality of work.
We wouldn't hesitate to recommend them to any of our friends and family, and we will work with them again if we have a new project.
