Preferred Glass & Windows is a family-owned custom glass and window shop covering Pacoima out of our Santa Clarita workshop, backed by 50+ years serving Santa Clarita Valley. Frameless shower enclosures templated to mid-century tract bathrooms, dual-pane window upgrades for one of the hottest corners of the Valley, custom-cut mirrors for bath remodels, and glass railings for stairs and pool surrounds. Every Pacoima job starts with a free on-site measure. Request a free quote and we will measure on site.
We fabricate and install custom frameless shower doors and enclosures for Pacoima homes, cut to the opening we measure rather than to a nominal kit size. Showers are the work we do most, and the fit is the whole job. Panels are 3/8" or 1/2" tempered safety glass, hardware-mounted into the wall studs and the curb, with no perimeter channel around the panel to hold soap film or corrode. Common configurations here are sliding panels for tub-to-shower conversions, hinged swing doors, and neo-angle units where the shower sits in a corner.
Most Pacoima houses went up between 1940 and 1969, and those original bathrooms are usually narrow and rarely square, so we template each enclosure against the actual walls and curb before anything is cut. That step is what keeps a door swinging true instead of dragging after a season. The old framed unit comes out, the template goes in, and the finished glass gets set on one work order.


Glass railing systems go in on Pacoima decks, second-story balconies, interior stair openings, and pool surrounds. We install frameless structural panels set into a base shoe, post-and-clamp systems along deck edges, and standoff fittings for stair runs and landings.
Panels are tempered safety glass, generally 3/8" for interior runs and 1/2" for anything outside, with tempered laminated used where the span or the exposure calls for it. Thickness gets sized to the span and the wind load, not picked off a chart. Every railing is specced to clear California's current guardrail-height requirement, with hardware spacing and anchoring worked out for the substrate underneath, whether that is wood framing, a concrete deck, or a masonry curb.
Window work splits two ways: a glass-only replacement that drops a new insulated unit into the frame you already have, and a full-unit replacement when the frame itself is past saving. Foggy glass is the call we take most. When the seal on an insulated glass unit fails, moisture gets between the panes and the haze never wipes off, and swapping the unit alone is quicker and cheaper than pulling the whole window.
Pacoima runs hotter than most of the Valley, with July highs averaging in the high 80s and summer peaks recorded past 100 degrees, so the original single-pane aluminum windows still hanging in a lot of these mid-century houses are doing almost nothing to hold that heat outside. Dual-pane insulated glass with a Low-E coating is the standard fix, and California's current energy code sets the U-factor and Solar Heat Gain Coefficient numbers replacement glass has to meet. We spec to those numbers without tying the homeowner to one manufacturer.
We cut, deliver, and hang custom mirrors for Pacoima bath and entryway remodels, closet doors, and home gym walls. Sizes come off a site measure, not off a nominal dimension, so the panel lands tight to the backsplash and the outlets and switch plates fall where they should.
Edges can be flat-polished for a plain finish, beveled for a framed look without a frame, or seamed where the mirror hides behind a cabinet return. Residential wall mirrors are typically 1/4" thick. Mounting is either clip-set, which lets the mirror come down later without damage, or full-surface adhesive with concealed clips on wide vanity runs. Safety backing is available on anything hung over a tub.

Specialty glass covers the pieces that are neither a shower nor a window. Frosted, satin-etched, reeded, and obscure-textured glass gets used for shower walls, partition inserts, sidelights, and bathroom windows where a Pacoima homeowner wants daylight without a sightline into the yard next door. All of it is custom-cut off a site measure.
Wine cellar enclosures are the other half. Cellar glass is typically dual-pane insulated so the temperature and humidity difference does not condense on the room-side face, framed on the full perimeter or butt-glazed frameless depending on the design.

Glass partitions split a room without closing it off. We install floor-to-ceiling frameless panels, short half-walls that give a desk some privacy, and framed systems when the run needs a swing door, a lock, or a sound break.
All partition glass is tempered safety glass, with thickness matched to panel height and span, and exposed edges polished. Mounting options are a bottom sill channel on its own, top-and-bottom channel for taller panels, or full perimeter framing when the wall needs to knock down noise. Frosted, satin-etched, and reeded glass handle the cases where privacy matters more than sightline, common in Pacoima home offices and small commercial buildouts along the San Fernando Road and Van Nuys Boulevard corridors.
Yes, we serve Pacoima from our Santa Clarita workshop, a straight run down the I-5 and 118 corridor into the northeast San Fernando Valley. The same crews that work Santa Clarita handle Pacoima frameless showers, window replacement, mirrors, and railings, and every job opens with a free on-site measure.
Frameless shower door cost in Pacoima is set by the opening, not by a catalog size. Price moves with opening width and height, glass thickness (3/8" or 1/2"), hardware finish, and whether the unit is a single panel, a slider, or a multi-panel enclosure. Every Pacoima enclosure is templated to the actual opening, so request a free on-site measure for a local quote.
Usually yes, though a like-for-like swap qualifies for a simplified express permit rather than a full plan review. Pacoima sits inside the City of Los Angeles, so the Los Angeles Department of Building and Safety is the permitting authority. When the new window matches the existing size, opening type, and location, the work generally moves through the LADBS e-permit path. Changing the size or the opening type pushes it to a standard permit. Replacement windows in low-rise homes also have to be dual-glazed and NFRC-labeled under California's current energy code. Ask us to confirm the path before ordering.
Yes. Pacoima July highs average around 87 degrees with summer peaks recorded past 100, and dual-pane insulated glass with a Low-E coating cuts solar heat gain sharply compared with the single-pane aluminum windows still common in homes built between the 1940s and the 1960s. Request a free on-site measure.
Yes. Older Pacoima bathrooms are rarely square, so the enclosure gets templated to the actual opening instead of ordered as a stock kit. Panels are cut from 3/8" or 1/2" tempered safety glass to the measured dimensions, and removal of the existing door is included. Book a free site measure.
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 northeast San Fernando Valley within the City of Los Angeles, Pacoima, California is one of the Valley's oldest and most culturally rich neighborhoods, spread across roughly seven square miles. Its name comes from a Fernandeño-Tataviam and Tongva word — often translated as "the entrance" or "running/flowing waters" — referencing the nearby Pacoima Wash, and the area was home to Native peoples long before Los Angeles annexed it in 1915. A proud, working-class, majority-Latino community with a longstanding Black community whose roots trace to the mid-20th-century Great Migration, Pacoima is the birthplace of rock 'n' roll pioneer Ritchie Valens, celebrated each year at the La Bamba Festival. It's known for its vibrant "Mural Mile" public art along Van Nuys Boulevard, its beloved local food, and the vast Hansen Dam Recreation Area.
