Preferred Glass & Windows is a custom glass and window shop serving Agua Dulce homes from our Santa Clarita shop, right next door, a short drive across the valley. We build frameless shower enclosures for custom ranch baths, glass railings on view decks, wine-room glass for vineyard-area homes, and dual-pane window upgrades for the high-desert climate. Every Agua Dulce job starts with a free on-site measure and a written quote, so the spec, glass, and timeline are set 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.
Agua Dulce's custom and ranch homes rarely have standard shower openings, so we template 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 natural fit on Agua Dulce's large-lot, hillside, and view-lot homes, where open glass panels preserve the sightline that framed pickets or cable runs interrupt. We install them on deck edges, second-story balconies, and interior stair runs.
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: a glass-only swap into an existing window frame, and full-unit replacement when the frame itself is shot. Many 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.
Agua Dulce sits above 2,500 feet, where strong sun and wide day-to-night temperature swings put real stress on older single-pane glass, and custom homes here often need larger, non-standard replacement units. 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 Agua Dulce bath and home-gym remodels, entryways, closets, 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-room and wine-cellar glass enclosures, decorative glass, and specialty fabrications round out the catalog. Wine-room glass is typically dual-pane insulated to hold the temperature and humidity differential without sweating on the room-side face, with full-perimeter framing or frameless butt-glazed seams depending on the design.
In Agua Dulce's vineyard-country setting, climate-controlled wine displays are a natural addition to larger custom homes. Specialty options include frosted, satin-etched, reeded, and obscure-textured glass for shower walls, partitions, and decorative panels, all custom-cut and measured on site.

Glass partition walls open up Agua Dulce home offices in custom and ranch properties, converted outbuildings, 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, PGM serves Agua Dulce from our Santa Clarita shop, a short drive southwest via Agua Dulce Canyon Road and Sierra Highway. The same install crews run Agua Dulce jobs, including frameless showers, window replacement, mirrors, glass railings, and wine-room glass.
Frameless shower doors typically run $900 to $1,900 installed nationally, with larger or custom configurations running higher. Every Agua Dulce shower is templated on site, so the quote reflects the actual opening rather than a kit price. Request a free on-site measure for an Agua Dulce-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 Agua Dulce does not require a permit, but full-frame replacement, opening size changes, and egress modifications typically do. Agua Dulce is unincorporated Los Angeles County, so permits run through the Los Angeles County Department of Public Works, Building and Safety, not the City of Los Angeles.
Yes, PGM builds custom wine-room and wine-cellar glass enclosures for Agua Dulce homes. The glass is typically dual-pane insulated to hold the temperature and humidity differential for a climate-controlled display without sweating on the room-side face.

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!!!
