About Us

Founded in 2009 in Glendale, California, Fusion Windows is a licensed, bonded, and insured window & door contractor serving Los Angeles, including Burbank, Glendale, Pasadena, and the San Fernando Valley. What began as a two-installer shop has grown into a full-service team specializing in energy-efficient window replacement, custom door installations, and precision retrofits for homes and light commercial projects.

Fusion Windows is an accredited business by the Better Business Bureau and have experience with just about every type of installation you can imagine. Our promise is simple: beautiful design, durable materials, and code-compliant installations, delivered with clear timelines and zero surprises.

Our Mission & Values

Fusion Windows’ mission is to improve comfort, efficiency, and curb appeal with high-performance windows and doors, designed well, installed right, and built to last.

Values we practice on every project:

Customer First

Clear communication from estimate to final walk-through. You get itemized proposals, realistic timelines, and a single point of contact. We explain options (vinyl, fiberglass, aluminum, glazing, and hardware) in plain language so you can choose what fits your budget, style, and energy goals.

Quality Workmanship

Installations are performed by certified crews following AAMA/manufacturer specifications, with site protection, clean removal/haul-away, and a documented quality checklist. We handle permits/HOA coordination and ensure Title 24/code compliance. Work is backed by our installation warranty in addition to manufacturer coverage.

Innovation & Sustainability

We prioritize energy-efficient, low-maintenance materials and NFRC-rated / ENERGY STAR® products appropriate for Southern California climate zones. Expect options like low-E glass, low-U-factor packages, sound-control laminates, and modern hardware that improves security and durability. Whenever possible, we recycle old frames/glass and recommend designs that reduce lifetime maintenance.

Romney Taylor

I’ve had two fantastic experiences with Fusion. Tony and his team managed to get our bi-fold doors back in working order. Quick to respond, clear on quoting, and professional and communicative throughout. Highly highly recommended.

Steve / Lou Everett

Tony and his son were absolutely fantastic. Had a bifold where the mechanism had broken and we couldn’t open the doors. Really lovely to find honest, value for money experts who know their stuff. Have done a fabulous job with the repair and doors are like new. Highly recommend.

Ele Marmor

Amazing service. Tony and his son were professional, punctual, reliable and provided a very high quality of work. After using many other companies in the past I will only be using Fusion Window and Door Maintenance Ltd in the future. Outstanding service!
