What Seattle Businesses Say
Our restaurant’s HVAC failed during a Friday dinner rush. Day & Nite had a technician there within the hour. They fixed it fast, were discreet around our customers, and the pricing was very fair. They’re our go-to for all commercial service.
We’ve used Day & Nite for our office building’s plumbing and electrical for three years. Their maintenance contract saves us money and headaches. Professional, on time, and they always clean up after themselves. Highly recommend.
Day & Nite installed a generator and full electrical upgrade for our retail location. The project was completed on schedule, on budget, and with zero disruption to our business hours. Excellent commercial contractor.
