Preferred Glass & Windows is a family-owned custom glass and window shop serving Mission Hills homes from our Santa Clarita Valley headquarters, 50+ years in the trade. We handle frameless shower swaps in mid-century ranch bathrooms, dual-pane window upgrades for west-facing SFV heat, custom mirrors for bath remodels, and glass railings on hillside decks. Every Mission Hills job starts with a free on-site measure and a written quote, so the spec, glass, and timeline are locked before any deposit. Request a free quote and we'll measure on site.
Frameless shower doors and enclosures are our bread and butter. We build every door to fit the opening, not a kit. Each enclosure is fabricated from 3/8" or 1/2" tempered safety glass, hardware-mounted to the wall and curb, with no perimeter metal frame to trap soap film or rust out. Configurations include sliding, hinged, and pivot doors, plus neo-angle enclosures for corner installs.
Mission Hills' mid-century ranch bathrooms rarely have square shower openings after decades of settling and tile retrofits, which is why our team templates every enclosure on site before fabrication. That custom-fit process is the difference between a door that closes cleanly for twenty years and a kit unit that drags inside of two. We handle the tear-out of the old framed door, the template, the order, and the install as one job.
Glass railings are a Mission Hills favorite on hillside view decks, second-story balconies, and interior stair runs along the foothill edge of the San Fernando Valley. Open glass panels preserve the sightline that framed pickets or cable runs interrupt.
We install three main styles: frameless structural panels set into a base shoe, post-and-clamp systems for deck edges, and standoff fittings for stairs and balconies. All panels are tempered safety glass, typically 3/8" interior or 1/2" exterior, sized for wind load and span. California building code requires a 42" minimum guardrail height on residential decks and balconies, and we spec every railing to clear that baseline with the right glass thickness, hardware spacing, and post anchoring for the substrate.
Window glass replacement covers two jobs: glass-only swap into an existing window frame, and full-unit replacement when the frame itself is shot. Most Mission Hills calls are foggy dual-pane glass, where the insulated glass unit seal has failed and moisture is trapped between the panes. We can pull the failed unit and install a new dual-pane insulated unit into the existing frame, which is faster and cheaper than a full-frame replacement.
San Fernando Valley summers run hot and dry with heavy west-facing sun, and Mission Hills' mid-century housing stock still carries plenty of original aluminum single-pane windows, which is why dual-pane Low-E upgrades pay back in cooling cost and interior comfort. California Title 24 energy code sets the U-factor and Solar Heat Gain Coefficient targets new and replacement glass has to clear. We spec to those targets without locking the homeowner into a single manufacturer.
Custom-cut mirrors are measured, fabricated, and installed for Mission Hills bath and entryway remodels, closets, home gyms, and wall-to-wall vanity runs. We cut to the exact opening so the mirror lands flush against the wall or backsplash with no gap to caulk.
Edge options include polished, beveled, and standard flat-polish finishes. Mounting can be clip-set for a clean recessed look, or full-surface adhesive with hidden support clips for larger wall-to-wall installs. Glass thickness is typically 1/4" for residential walls, with safety backing available on installs over a vanity or tub. Every mirror is templated to the actual wall, not ordered from nominal dimensions, so corners, outlets, and switch plates line up the first time.
Wine cellar enclosures, decorative glass, and specialty fabrications round out the catalog for Mission Hills 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.
Glass partition walls open up Mission Hills home offices, converted garages, and small commercial buildouts without losing daylight to a drywall split. We install floor-to-ceiling frameless partitions, short half-walls for desk privacy, and framed partitions where a mounted door or sound break is needed.
Glass is tempered safety throughout, with thickness sized to the panel height and span. Edge treatment is polished on all exposed edges. Mounting can be sill-channel only, top-and-bottom channel for taller spans, or full perimeter framing for a sound-rated install. Frosted, satin-etched, and reeded glass are available where privacy matters more than transparency, which is the common ask for home-office partitions facing a hallway or shared room.
Yes, we serve Mission Hills from our Santa Clarita Valley headquarters, about 20 miles north via I-5 and the I-405 / Sepulveda Blvd corridor. The same install crews run Mission Hills jobs, including frameless showers, window replacement, mirrors, and glass railings.
Frameless shower door cost in Mission Hills varies with opening size, glass thickness, hardware finish, and configuration. Every Mission Hills shower is templated on site, so the quote reflects the actual opening rather than a kit price. Request a free site measure for a Mission Hills-specific quote.
Frameless shower doors use 3/8" or 1/2" tempered safety glass with no perimeter metal channel; the glass is hardware-mounted to the wall and curb. Framed doors use thinner glass, typically 3/16", set inside a continuous aluminum frame that supports the panel. Frameless units are custom-templated to the actual opening, while most framed doors are kit-sized to nominal openings. Frameless gives a cleaner look, fewer soap-film traps, and longer service life; framed runs cheaper and faster to install but shows the metal channel and tends to leak at the seal sooner.
Most like-for-like window glass replacement in Mission Hills does not require a permit. Full-frame replacement, opening size changes, and egress modifications typically do. Mission Hills falls within the City of Los Angeles, so the Los Angeles Department of Building & Safety (LADBS) is the permitting authority.
Most custom glass projects in Mission Hills run two to four weeks from site measure to installation. The cadence is template on site, fabricate, then install once glass and hardware arrive. Standard window swaps run faster; custom frameless showers and large mirror walls land longer.
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!!!
