Quantum Windows & Doors

Wood frame windows & Doors

At Quantum we strive to build the most beautiful custom wood window and door systems available anywhere.  Our product offerings cover a comprehensive range of solutions for higher-end residential, commercial, and historic applications.  Founded in 1982 as a response to the industry’s demand for a better built custom wood window, Quantum’s founders were general contractors dissatisfied with the mass produced windows available and they demanded a level of craftsmanship on par with the luxury homes they were building.  Response to our quality products was excellent and our reputation grew quickly.  We never compromise when it comes to our manufacturing procedures – our facility in Everett, Washington is designed to maximize craftsmanship and attention to detail throughout the whole production process – we are known for our exceptional joinery, our true divided lites are without equal, and our in-house glazing and finishing operations provide unparalleled control over product quality.  From its humble beginnings in a contractor’s garage, Quantum has grown into an international industry leader and our portfolio speaks for itself.  Please take the time to visit Diversified’s showroom – once you have witnessed the beauty of the wood we use and seen the innovative quality of our European clad design you will have a better appreciation for why our reputation is unmatched in our industry.
