Preferred Glass & Windows is a family-owned Santa Clarita Valley glass shop, and we run jobs out to Simi Valley homes on the SR-118 corridor. 50+ years serving Santa Clarita Valley sits behind the work: frameless shower enclosures in remodeled ranch bathrooms, glass railings on hillside view decks, custom mirrors for bath and entry remodels, and dual-pane window upgrades built for inland summers. Every project starts with a free on-site measure and a written quote. Request a quote to get on the schedule.
Custom frameless shower doors and enclosures for Simi Valley homes are fabricated to the actual opening, templated on site before any glass is cut. Each enclosure is cut from 3/8" or 1/2" tempered safety glass and hardware-mounted to the wall and curb, with no perimeter metal channel to trap soap film or corrode. Configurations include sliding, hinged, and pivot doors, plus neo-angle units where the opening turns a corner.
Plenty of central Simi Valley's mid-century ranch bathrooms sit out of square after decades of settling and remodels, so the template is what separates a door that closes cleanly for years from a kit unit that starts dragging inside a season. A kit door is built to a nominal size and shimmed to fit. A custom enclosure is built to the measurement. Tear-out, template, fabrication order, and install all run through one shop.
We install residential glass railing systems for decks, balconies, and interior stair runs. Style families include frameless structural panels set in a base shoe, post-and-clamp systems, and standoff hardware fixed through the panel face. Panels are tempered safety glass, typically 3/8" for interior runs and 1/2" for exterior, with tempered laminated glass the usual call on open exterior spans.
Simi Valley's master-planned hillside developments, including Wood Ranch and Big Sky, were built around the view, and glass panels keep those sightlines open on decks and balconies where a picket or cable rail would cut them up. Every railing is specced to clear current California guardrail-height code, with glass thickness, hardware spacing, and anchoring sized to the substrate and the span.
Window glass replacement covers two different jobs. The first is a glass-only swap, where the insulated glass unit comes out and a new dual-pane unit goes back into the existing frame. The second is full-unit replacement, which is the call when the frame itself has failed. Foggy glass is the most common trigger: the IGU seal gives up, moisture gets between the panes, and no amount of cleaning touches it.
Central Simi Valley's mid-century ranch homes still carry a lot of original single-pane glass, and inland summers in the high 80s put steady thermal load on older dual-pane units until the seals let go. Dual-pane Low-E replacements cut solar heat gain and hold conditioned air where it belongs. California's current energy code sets the U-factor and solar-heat-gain numbers replacement glass has to hit. We work to those numbers and stay material-agnostic on the frame.
We fabricate and install custom-cut mirrors for Simi Valley bath and entry remodels, walk-in closets, home gyms, and full vanity walls. Sizes come off the wall itself, not off a nominal dimension, which is why outlets, switch plates, and out-of-plumb corners land where they should on the first hang.
Edges are finished polished, beveled, or flat-polished depending on the look. Mounting runs clip-set for a recessed reveal, or full-surface adhesive with concealed clips on larger spans. Residential wall mirrors are typically 1/4" glass, with safety backing where the mirror sits over a vanity or tub. Frameless mirror walls, framed vanity pieces, and antiqued or tinted glass are all made to order.
Wine cellar glass enclosures and specialty fabrication round out the catalog for Simi Valley homes adding a climate-controlled wine display. Cellar glazing is typically dual-pane insulated so the enclosure holds its temperature and humidity differential without sweating on the room-side face, with full-perimeter framing or frameless butt-glazed seams depending on the design.
Specialty glass covers frosted, satin-etched, reeded, and obscure-textured panels for shower walls, partitions, cabinet inserts, and decorative features. All of it is custom cut and measured on site.
Glass partition walls split a room without splitting the daylight. We install floor-to-ceiling frameless partitions, partial-height panels for desk privacy, and framed partitions where a swing door or a sound break is part of the plan, common asks for Simi Valley home offices and small commercial suites.
Glass is tempered safety throughout, with thickness sized to panel height and span. Exposed edges are polished. Mounting options include sill channel only, top-and-bottom channel on taller spans, and full perimeter framing where the partition needs to carry a door or a gasketed seal. Frosted, satin-etched, and reeded glass are available where privacy matters more than a clear sightline.
Yes. Our Santa Clarita Valley glass shop covers Simi Valley homes, about 30 miles out on the SR-118 corridor. The same crews handle frameless showers, window replacement, custom mirrors, and glass railings there. Request a free on-site measure to get started.
Frameless shower door pricing is set by the opening rather than a catalog size, so the number comes from a measure. Four variables move it most: glass thickness (3/8" or 1/2"), opening size, hardware and finish, and whether the unit is a single door or a multi-panel enclosure. Request a free on-site measure for a written Simi Valley quote.
Window permits in Simi Valley are handled by the City of Simi Valley Building & Safety Division. Simi Valley is an incorporated city in Ventura County, so the authority is not the Los Angeles Department of Building & Safety and not the Ventura County Building & Safety Division, which covers unincorporated areas only. Whether a permit is required varies by scope of work, so confirm your project with the Building & Safety Division before anything is ordered. Request a free on-site measure and we will spec the glass.
Frameless shower doors use 3/8" or 1/2" tempered safety glass with no perimeter metal channel, hardware-mounted to the wall and curb and templated to the actual opening. Framed doors use thinner glass, commonly 3/16", set inside a continuous metal frame and usually fitted to a standard kit size. Frameless costs more and traps less soap film. Framed installs faster.
Yes. Glass railing systems install on residential decks, balconies, and stair runs, including view decks in Simi Valley's hillside developments. Exterior panels are tempered or tempered laminated safety glass, typically 1/2" thick, and every railing is specced to clear current California guardrail-height code. Request a free on-site measure for a railing quote.
I loved going with Preffered Glass as it was recommended by a family friend to fix my antique hutch cabinet. I spoke with Courtney and I needed 2 new pieces for my doors. She was great she got the measurements I needed and what I wanted. She got the work done same day. And when I installed the pieces one needed to be cut a little more because it was a little to big. She personally went to the back and cut the piece I needed so it can fit properly. 10 out of 10 recommend for all your Glasswork needs.
Preferred Glass & Windows is an amazing company to work with beginning to end on any project! Scott came to my house to give me a quote on shower doors for my master bath and on all my windows. He was extremely professional and helpful and made sure everything went smoothly! Courtney at the front desk was super friendly as well and very knowledgeable and she had no problem answering any of my questions! The customer service was top tier and the installation job was even better! I will definitely be a returning customer.
We had a broken window called for service to replace it. They came the next day measured the window said it would be a week or two to get the window call the next day. The window came in sooner than expected, they came that afternoon and installed it it came out great very impressed with their level of service. Thank you very much!!!

Located in the southeast corner of Ventura County about 40 miles northwest of downtown Los Angeles, Simi Valley, California is a scenic suburban city of roughly 126,000 residents, incorporated in 1969 and ringed by the Santa Susana Mountains and Simi Hills. Its name comes from the Chumash word "Shimiyi," and the area was part of the 1795 Spanish land grant Rancho Simi long before the city grew up around it. Best known as the home of the Ronald Reagan Presidential Library and Museum — the largest presidential library in the country, complete with a retired Air Force One and President Reagan's final resting place — Simi Valley is also prized for its mountain views, nearly 40 parks, film-history landmarks like the old Corriganville movie ranch, and a safe, family-oriented feel just over the Santa Susana Pass from the San Fernando Valley.
