Completed Squamish project
★★★★★
“Working with Gabriel on our Aux Box was a great experience from start to finish. The build itself came together smoothly and right on schedule.
The fixed price contract also ensured we didn’t have to pay more than we signed up for, even when unexpected costs came up.”
