Preferred Glass & Windows has been fabricating custom glass for Northridge homes and businesses for 50+ years, working out of our Santa Clarita workshop about 22 miles north on the 5. Frameless shower enclosures for primary bathroom remodels, window replacement on 1970s-era tract homes near CSUN, custom mirrors for vanity upgrades, and glass railings for hillside decks and interior stair runs. Request a free quote and we will measure your project on site.
We fabricate and install custom frameless shower doors and enclosures for Northridge homes, templated on site to the actual opening so the glass fits the room, not a nominal kit size. Our team handles fully frameless layouts, semi-frameless and hinged door configurations, sliding bypass systems for tubs, and inline panels for walk-in showers. Glass is typically 3/8" or 1/2" tempered, selected based on door size, hardware load, and the bathroom's design direction.
Northridge's mix of 1950s and 1970s ranches near CSUN often features non-square shower openings that off-the-shelf kits cannot accommodate; newer custom builds in the Devonshire neighborhood and along the Porter Ranch border favor full frameless for high-end bathroom remodels. Either way, on-site templating means the enclosure lands square against tile or stone the first time. Pair this section with our Custom Frameless Shower Doors service page for full specs.
We install glass railing systems for Northridge homes and businesses, including frameless, post-and-clamp, and top-rail-capped styles. Use cases include interior stair runs, exterior balconies, hillside decks on north Northridge and Devonshire-area lots, pool surrounds, and balcony retrofits on CSUN-adjacent rental properties. Interior runs typically use 3/8" tempered glass; exterior decks and balconies use 1/2" tempered laminated glass to meet California guardrail requirements.
California building code requires a minimum 42" guardrail height on open sides of decks, balconies, and mezzanines. Every railing project is specced and installed to current code, with hardware sized to the glass and the substrate at each post or clamp location. See our Glass Railing Installation page for system options.
Northridge is a window-replacement market. We install energy-efficient dual-pane windows for whole-home and partial replacement projects, and we swap failed insulated glass units (IGUs) where the frames are still sound and only the sealed glass pack has fogged or failed. Most Northridge tract homes pre-date California's current energy code, so original single-pane or early dual-pane windows drive a heavy summer cooling load in San Fernando Valley heat. Replacing them is one of the highest-leverage upgrades a 1970s-era Northridge home can make.
Whether you need a full home retrofit or a single broken IGU swapped, the path starts the same way: an on-site measure and a written quote.
We cut and install custom mirrors for Northridge homes: bathroom vanity mirrors, full-wall installations, home gym mirrors, closet door mirrors, and decorative pieces sized to the room. Edge profiles include polished, beveled, and flat polish; substrates are cut to size and templated for outlets, sconces, switches, and any wall-mounted hardware that the mirror needs to clear cleanly.
Vanity-mirror upgrades are a common pairing with frameless shower work in Northridge mid-century and ranch bathrooms, and full-wall mirrors are a recurring request for home gyms in larger Devonshire and Northridge Fashion Center-adjacent properties. Bring measurements or schedule an on-site template. Cross-reference with our Custom Cut Mirror Installations page for finishes and edge details.
Wine cellar enclosures, decorative glass, and specialty fabrications round out the catalog for Northridge homes adding climate-controlled wine displays, art-glass features, or frosted shower walls. Wine cellar glass is typically dual-pane insulated to hold the cellar's 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 options include frosted, satin-etched, reeded, and obscure-textured glass for shower walls, partitions, and decorative panels. All custom-cut, all measured on site.
We install interior glass partition walls for home and light commercial use, including home office dividers, conference room walls, retail and tenant fit-out partitions, and glass walls that close off shower areas in larger primary bathrooms. Options run from fully frameless panels with minimal hardware to framed systems with aluminum perimeters, and the glass itself can be clear, low-iron for a cleaner edge color, frosted for privacy, or textured to soften light.
Partitions are common across Northridge's newer custom builds and converted garage office spaces. Every panel is cut to the opening, polished on exposed edges, and installed with the appropriate clamp, channel, or standoff hardware for the substrate. See our Glass Partition Installation page for system layouts.
Custom frameless shower door pricing in Northridge varies by glass thickness (3/8" vs 1/2"), hardware finish, opening size, and whether the layout includes a return panel or fixed inline glass. We quote every project on site after templating the opening, so the number reflects the actual door, not a kit estimate. Request a quote to start.
Like-for-like residential window replacement in Northridge typically does not require a building permit, but expanding an opening, structural changes to the surrounding wall, or new construction does require one. Northridge falls under City of Los Angeles jurisdiction, so permits route through LADBS (Los Angeles Department of Building and Safety). We handle standard like-for-like residential replacement directly; structural alterations are routed to a general contractor partner.
Custom frameless shower door installation in Northridge typically takes 2 to 3 weeks from on-site measure to install. The breakdown: on-site template (about one hour), fabrication at our workshop (roughly two weeks for tempering and edge work), and the install itself (about half a day for a standard enclosure). Request a quote to start the clock.

Yes. We install glass railing systems on residential decks, balconies, and stairs across Northridge, including hillside lots in north Northridge and Devonshire. Exterior railings are specced in 1/2" tempered laminated glass to meet California's 42" minimum guardrail height on open sides of decks and balconies. Request a quote to schedule a site visit.
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!!!
