We Offer Custom Showers, Window & Door Repair, Custom Mirrors, Tabletops & Shelves, Railings, & Commercial Glass in the Santa Clarita Valley. AAMA-certified, in-house installers, no subcontractors. Family-owned since 1969.
Glass work in this valley has real variables. Older homes have walls that haven't been square in years, and aluminum frames expand and contract more than most people expect in this heat. At Preferred Glass & Windows, we measure everything in person before cutting anything. No phone quotes, no outsourced crews. We've done it this way since 1969 because what's in the wall matters more than what's on a spec sheet. We do bathroom remodels, storefront replacements, and custom wine cellars in new builds — all fabricated and installed by our own team.
A frameless shower performs best when the enclosure is built to match the exact conditions of the space, since walls shift, slabs settle, and tile lines rarely sit perfectly square. Custom measured frameless shower doors and enclosures follow the true structure of the room to maintain proper alignment, smooth door operation, and consistent water containment. The result is a clean appearance, reliable performance, and a shower enclosure that continues to function properly for years after installation. 🚿

A mirror should sit flat, align cleanly, and remain securely mounted for years of daily use. Custom-cut mirrors are measured for precise fit and installed with secure mounting methods that maintain alignment and structural stability. Proper installation helps prevent edge blackening, adhesive failure, and separation from the wall while delivering a clean, durable finish.

A damaged window often affects more than appearance. Sun exposure and daily expansion cycles can weaken seals, spread cracks, and cause insulated glass units to fog, reducing clarity and insulation performance. Professional window glass replacement restores visibility, improves energy efficiency, and preserves structurally sound frames through precise measurements, proper seating, and correct glazing methods.

Open layouts lose comfort when noise travels and privacy disappears. A properly designed glass partition restores separation while maintaining light, openness, and visual flow. Residential glass partitions anchor securely, align precisely, and remain stable under daily use, creating a clean architectural feature that improves privacy and preserves the open feel of the space.

A glass railing should feel solid the first time someone leans against it. Proper anchoring and precise alignment support panel stability, reduce flex, and maintain consistent performance under daily use. Professionally installed glass railing systems deliver dependable strength, clean sightlines, and long term structural confidence for elevated decks, balconies, and stairways.

A glass wine cellar should protect the collection inside while maintaining stable temperature and humidity. Poorly sealed enclosures can strain cooling systems, cause condensation along glass edges, and allow conditioned air to escape. Custom glass wine cellars are designed for tight sealing, secure anchoring, and reliable climate control that preserves wine and enhances the surrounding space.

Fog between panes indicates a failed seal inside the insulated glass unit, not a surface cleaning issue. Moisture enters the sealed cavity when perimeter seals break down from heat exposure and daily expansion cycles, leaving windows cloudy and reducing clarity. Replacement of the insulated glass unit with precise measurement, proper setting block placement, and correct glazing compression restores visibility, improves energy performance, and helps the window system perform reliably over time.

Glass doors should glide smoothly, close cleanly, and remain properly aligned over time. Heavy panels, constant use, and structural movement can wear rollers, shift hinges, or pull frames slightly out of alignment, leading to difficult operation and reduced reliability. Professional glass door installation and repair restore proper balance, adjust hardware, and ensure safety-compliant glazing so doors operate smoothly, seal correctly, and maintain long-term performance.

Broken glass immediately impacts safety, comfort, and home security. Cracked windows, shattered patio doors, and damaged entry panels require fast stabilization to protect the structure and prevent further risk. Emergency residential glass repair restores safety through controlled removal, temporary protection, and a clear path toward permanent replacement.

Decorative glass must fit the frame precisely to prevent rattling, binding, or edge stress. Professional installation ensures correct glass thickness, balanced glazing pressure, and secure seating that supports long term stability. Properly fitted decorative and specialty glass improves appearance, maintains structural integrity, and performs reliably under everyday door movement and environmental exposure.

A shower door kit performs reliably only when installation accounts for real structural conditions. Slight wall lean, uneven curbs, and inconsistent backing behind tile can cause leaks, misalignment, and door drag when not properly addressed. Professional installation ensures precise alignment, secure anchoring, smooth door movement, and long-term stability.

A glass table top must sit flat, distribute weight evenly, and withstand daily use without developing stress fractures. Custom fabrication ensures precise sizing, proper load distribution, and stable placement across a wide range of table bases and furniture styles. The result is a durable, clean surface that protects the base while maintaining long term performance and visual clarity.

Glass shelving should support real weight without sagging, tilting, or pulling away from the wall. Proper fabrication and secure anchoring ensure shelves remain stable under everyday use while maintaining a clean, modern appearance. Custom glass shelving is designed to match wall structure and load requirements, creating durable storage and display solutions that perform reliably over time.

Commercial glass doors manage daily entry flow, maintain interior climate control, and serve as a critical layer of building security. When doors drag, rattle, fail to latch, or develop glass damage, the problem quickly impacts safety, energy efficiency, and the professional appearance of the property. Professional installation and repair restore smooth operation, precise alignment, and durable hardware performance designed for continuous daily use.

Conference rooms and reception areas experience constant daily use as chairs contact edges, equipment shifts across surfaces, and routine cleaning places repeated stress on furniture materials. Commercial glass tops and conference surfaces provide durable, stable workspaces designed for high traffic professional environments. Precision fabrication, balanced load support, and clean edge finishing protect furniture while maintaining a polished appearance that performs reliably under continuous use.

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!!!
