These guys are great. I am glad I went with them over some of the larger company's in the area. Very Happy with the results. They set up a whole suite of automation including colour changing LED's, LED deck Jets, Salt system and heater all controlled by an app on my phone. They also did the rubber rock on my pool deck themselves. Great job!!!!

QSI did work at my grand parents house years ago. Had them do our upstairs windows. Great workmanship, quality and service. The new windows are much quieter since we do back on to a busy road. Also notice them to offer much better insulation. Highly recommend QSI to anyone.
