“The Nonstop Company has been our exclusive supplier for 8 years. Their product quality and technical support are unmatched in the industry. When we needed emergency parts for a hospital project, they delivered within 4 hours.”
“As an architect specializing in LEED-certified buildings, I need suppliers who understand sustainability. NOTSP's WaterSense product line and EPD documentation made our certification process seamless.”
“We switched from a national competitor last year. The difference is night and day - better pricing, faster delivery, and their technical team actually knows the products. Our callbacks dropped 40%.”
“The contractor pricing program saved our business over $200K last year. But what really sets them apart is their training programs - my team is now certified in the latest smart home systems.”
“For our 500-unit apartment complex renovation, NOTSP provided complete project management. On-time delivery, no backorders, and they even helped us optimize our fixture specifications for water savings.”
“J'utilise The Nonstop Company depuis 10 ans pour tous mes projets au Québec. Leur service en français et leur connaissance des codes canadiens sont excellents.”
