A shower door kit is only as good as its installation — real bathroom openings are not standard dimensions, and a kit installed without accounting for wall lean or shifting curbs will leak. Glass shower door kit installation throughout Santa Clarita by Preferred Glass & Windows — AAMA-certified, no subcontractors, since 1969.
Standard kit dimensions are fixed, but bathroom openings vary once tile and finished surfaces are in. At Preferred Glass & Windows, we confirm actual measurements after tiling is complete — not before. Older homes from the 1960s and 70s often have walls that haven't been plumb in decades, and backing behind tile in those homes is inconsistent. If hinges and tracks don't anchor into solid structure, they pull loose.We locate anchor points before drilling on every job. We also check curb level and wall angle before a single component is set, because a sweep that doesn't sit flat on the curb is where most leaks start — not in the glass itself.
The right kit style depends on your bathroom layout and daily usage. We offer several configurations:
Every kit features tempered safety glass and load-rated hardware. Hinged kits include wall-mounted hinges, handles, and jamb seals, while sliding kits utilize header tracks, rollers, and door stops. We verify that all hardware is built for the specific glass weight before ordering.
Most leaks originate at the door sweep or jamb seal. Before drilling begins, we verify wall plumb, curb level, and tile condition. We plan the placement of seals and sweeps to ensure they run flat against the curb, even in older homes with mineral deposits. We test every door through repeated open-and-close cycles to confirm a perfect seal. If an opening falls outside standard kit dimensions, we can also fabricate a fully custom frameless enclosure to fit.
With over 55 years in the glass trade, our reputation is built on work that speaks for itself. We are AAMA certified, fully licensed, and insured. Local readers and publications have consistently recognized us as the top glass and window company in the Santa Clarita and San Fernando Valleys. Every installation carries a lifetime guarantee.
Not always. Kit dimensions are fixed, and real openings vary once tile and finished surfaces are in place. We check the actual finished opening before confirming a kit will fit and function correctly.
Yes. California building codes require tempered safety glass in wet areas. Every kit we install uses tempered glass panels.
Most leaks come from the installation, not the glass itself. A sweep that does not sit flat on the curb, a hinge that is not on a true plane, or a track that is not level are the typical causes. Correct setup at install prevents most of these problems.
Squeegee the glass after each shower to slow mineral buildup. Wipe down tracks and hinge areas regularly. Use a mild cleaner and soft cloth on glass and hardware. Avoid abrasive pads that scratch finishes and create surfaces where deposits grip faster.
Most installs are completed in one day. We walk you through the realistic timeline during the consultation so you know what to plan for.
A kit is a pre-packaged system built to standard dimensions. A custom frameless enclosure is fabricated specifically for your opening. If your bathroom layout falls outside standard kit sizes, a custom enclosure is the right call. We install both and will tell you honestly which one fits your situation.
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!!!
