Northern California’s Trusted Window Covering Specialists

SEI Window Coverings is a third-generation family business led by an owner with over 20 years of exclusive industry experience. Unlike big-box stores that outsource installations, SEI follows an 'install what you sell' philosophy. The same expert who consults and measures your windows also handles the installation, ensuring 1/16th-inch precision and full accountability. Our mobile showroom brings real material samples to your space, providing a personalized, pressure-free experience and eliminating miscommunication and costly errors. We serve clients from Redding to San Jose, covering all of Northern California.

We provide in-home design consultations, measurement, and installation services across 12 counties, including Sacramento, Roseville, Rocklin, Yuba City, Walnut Creek, Napa, Sonoma, Colusa, Glenn, Yolo, and San Jose. Whether you are in a historic Davis neighborhood, a Folsom home, or a Walnut Creek office, our mobile showroom comes to you. We do not operate a walk-in gallery; instead, we bring our expertise and materials directly to your windows throughout Northern California.

Our current focus is on replacing failing third-party window coverings with high-quality, warrantied solutions from Graber and Norman. We do not provide repairs for products we did not install. For clients with SEI-installed systems, we offer full warranty support and service work orders. This approach ensures lasting solutions, technical compatibility, and eliminates the recurring issues often found with out-of-warranty or mismatched products.

SEI Window Coverings specializes in custom shutters, solar shades, roller shades, wood and faux wood blinds, and motorized window coverings. We are an Executive Level Dealer for Graber and Norman, offering only high-quality products in wood, composite, vinyl, and cellular materials. Our mobile showroom includes real swatches so you can see how each option looks in your own lighting. We also provide smart home integration for power shades and scenes compatible with Alexa and Google Home.

Our process is fully integrated for accuracy and convenience. First, we schedule an in-home or on-site consultation with our mobile showroom to review samples and discuss your needs. Next, precise measurements (down to 1/16th of an inch) are taken by the same expert who will perform your installation. We order your custom window coverings directly from the manufacturer, then return for professional installation. This end-to-end approach ensures technical accuracy and full project accountability, from Sacramento to San Jose.

All shutter installations by SEI Window Coverings come with a lifetime installation warranty. Material warranties for Graber and Norman products are available and vary by product type. For specific coverage details, we will review warranty information during your consultation. Our warranty support is available exclusively for SEI-installed systems to guarantee technical compatibility and long-term peace of mind.

The average investment for a residential window covering project with SEI is around $4,000, though costs vary based on window size, material, and complexity. As an Executive Level Dealer, we offer direct-to-consumer pricing that is often more competitive than big-box retailers, thanks to lower overhead and manufacturer partnerships. Each estimate is custom-tailored during your consultation, ensuring transparency and value for every client in Northern California.
