Preferred Glass & Windows is a family-owned custom glass and window shop serving Chatsworth homes from our Santa Clarita workshop, with 50+ years serving Santa Clarita Valley behind every job. We build frameless shower enclosures, glass railings for foothill view decks, custom mirrors for bath remodels, and dual-pane window upgrades sized for San Fernando Valley heat. Every Chatsworth project starts with a free on-site measure and a written quote, so the glass, spec, and timeline are set before any deposit. Request a free quote and we will measure on site.
Our team fabricates and installs custom frameless shower doors and enclosures for Chatsworth homes, templated on site to the actual opening. Frameless showers are our bread and butter, and we build every door to fit the opening, not a kit. Each enclosure is cut from 3/8" or 1/2" tempered safety glass, hardware-mounted to the wall and curb, with no perimeter metal channel to trap soap film or rust out. Configurations include sliding, hinged, and pivot doors, plus neo-angle units for corner installs.
Many Chatsworth ranch and foothill homes have non-square shower openings after decades of settling, which is why we template every enclosure to the actual opening before fabrication. That custom-fit process is the difference between a door that closes cleanly for years and a kit unit that drags within months. We handle the tear-out, the template, the order, and the install as one job.
We install glass railing systems for Chatsworth homes, including frameless structural panels, post-and-clamp systems, and standoff styles. Open glass panels preserve the sightline that framed pickets or cable runs interrupt, which is why they suit view decks, second-story balconies, and interior stair runs.
Chatsworth's large-lot and foothill homes near the Santa Susana hills often have view decks and balconies where frameless glass railings keep sightlines open while meeting California guardrail-height code. 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 open sides of residential decks and balconies, and we spec every railing to clear that baseline with the right glass thickness, hardware spacing, and 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. Most Chatsworth calls are foggy dual-pane glass, where the insulated glass unit seal has failed and moisture is trapped between the panes. We 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 near 90 degrees, and Chatsworth's older ranch and tract homes still carry plenty of original single-pane windows, which is why dual-pane Low-E upgrades pay back in cooling cost and interior comfort. California's current energy code sets the U-factor and Solar Heat Gain Coefficient targets that 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 Chatsworth 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 Chatsworth 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 Chatsworth 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. Edges are polished on all exposed runs. 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 offices and small commercial spaces along the Devonshire and Topanga Canyon corridors.
Yes, our team serves Chatsworth, CA from our Santa Clarita Valley headquarters, about 25 miles away via SR-118 and the Santa Susana Pass corridor. Chatsworth borders the Santa Clarita Valley, so the same install crews run Chatsworth jobs, including frameless showers, window replacement, mirrors, and glass railings.
Frameless shower doors typically run $1,000 to $3,000 installed nationally, with custom enclosures higher depending on glass thickness, opening size, and hardware. Every Chatsworth shower is templated on site, so the quote reflects the actual opening rather than a kit price. Request a free site measure for a Chatsworth-specific quote.
Frameless shower doors use 3/8" or 1/2" tempered safety glass with no perimeter metal channel, and 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 installs faster, but shows the metal channel and tends to leak at the seal sooner.
Like-for-like window replacement in Chatsworth, where the new window matches the existing size, opening type, and location, generally qualifies for a simple e-permit. Changing the size or opening type requires a standard permit. Chatsworth falls within the City of Los Angeles, so the Los Angeles Department of Building & Safety (LADBS) is the permitting authority.
Yes, we install glass railing systems on residential decks, balconies, and stairs across Chatsworth, including foothill and hillside view properties. California code requires a 42" minimum guardrail height on open sides of decks and balconies, and exterior panels are tempered or tempered laminated safety glass.

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!!!
