For more than 20 years Quadrant Systems has kept Northwest families, builders and businesses on the cutting edge of systems and technologies.
Longevity is important where your job is concerned.
We stress quality and reliability, back up our work and document every job for future reference. Ten years from now, there’ll be no guessing about your wiring plan.
Our goal is to earn trust and referrals through excellent service.
Your needs: Our solutions. (All from just one source.)
Work with experts in all facets of home technologies. One representative, one company, one quality guarantee. Integration does make a difference.
Our more than 30 staff and technicians take pride in their work. Our technicians are employees not subcontractors, so you can trust them in your home. Our company is licensed and bonded, and insured to an exceptional $2 million, including for errors and omissions.
From whole house to a single room.
Whether you are building, remodeling or creating the home entertainment center of your dreams, talk to us. We’ll work directly with you or as a member of your construction team of builders, designers, architects, electricians and cabinet makers.
At Quadrant our passion is enhancing your lifestyle through the technologies we offer. We offer top products in every price range. Unlike most technology companies, we stock most products in our warehouse to avoid delays and keep your job on schedule.
We also stand behind our work, with a minimum one-year warranty on materials and workmanship.
