Custom Window Installations | SEI Window Coverings

At SEI Window Coverings, installation is not just an afterthought. It is the core of our service. With over 20 years of experience and a third-generation heritage in the window treatment industry, our focus is on getting every detail right, down to the 1/16th of an inch. We know that a window covering is only as good as its fit and function. That is why the same person who measures your windows is the one who installs your blinds, shades, or shutters. This approach eliminates miscommunication, reduces costly mistakes, and ensures that what you select is installed to exacting standards. Whether you are in Roseville, Walnut Creek, or San Jose, our mobile showroom comes directly to you, letting you see materials and finishes in your own lighting. From custom plantation shutters for unique window shapes to blackout shades for home theaters, our installation-first philosophy delivers reliability and lasting value.

Unlike big-box stores that outsource labor, SEI Window Coverings provides direct, warrantied installation from start to finish. Owner Trevor Smith brings decades of technical knowledge to every project, handling measurement and installation personally. This continuity ensures that every recommendation is practical and every promise is kept. Our installations stand out in homes and commercial spaces across Northern California, including high-value settings like luxury auto dealerships and federal offices, because we never rely on generic solutions. Our work is licensed, bonded, and insured (CSLB #1118434), and our status as a 2025 Executive Level Dealer for Graber and Norman gives you access to premium products at fair prices. When privacy, energy efficiency, or challenging windows are at stake, you can count on our honest approach and precision craftsmanship to get the job done right the first time.

Our process starts with a mobile showroom visit, serving communities from Colusa to Napa, Sacramento, and beyond. You review real samples in your actual lighting, with no showroom guesswork. Once you select materials, we measure each window to the nearest 1/16th of an inch, considering every detail from intricate tile to oversized panes. We then order directly from trusted manufacturers like Graber and Norman, ensuring quality and warranty support. Installation is performed by the principal himself, not a subcontractor, ensuring the highest level of accountability. For shutters, we back our work with a lifetime installation warranty. For other window coverings, we provide ongoing service and warranty support on all products we install, prioritizing long-term reliability. Our system eliminates the headaches and delays typical of sales-driven models, delivering a smooth project timeline and a finished product that enhances your space.

Choosing SEI Window Coverings means you are getting more than just a product. You are choosing expertise, direct communication, and a commitment to quality. We do not fix third-party installations because we believe in providing permanent solutions, not temporary fixes. Our team prioritizes replacement and warranty support for the products we install, ensuring your investment is protected for years to come. Whether you are a homeowner upgrading for energy efficiency or a commercial property manager needing durable, secure solutions, our installation service is designed to address your exact needs. With hundreds of original project photos and a reputation built on trust, SEI Window Coverings is the authority in window covering installation throughout Northern California.
