A glass repair call in Los Angeles usually starts with one of three problems: a shower door that leaks or drags, a scratch or haze on an otherwise good pane, or a crack that means the glass is done. Each one has a different fix, and some are not glass work at all. Knowing which is which saves a homeowner from paying to replace a panel that only needed a new seal.
Shower Door Masters has fabricated, installed, and serviced glass across Los Angeles and Orange County for more than 25 years, cutting every piece in-house to the measured opening. The shop repairs and replaces frameless shower enclosures, glass railings, shelving, tabletops, and wall mirrors, and services the hardware that holds them. Book a consultation before any work starts, so the fix matches the actual problem.
What Can Be Repaired and What Has to Be Replaced
Most glass “repair” splits along a hard line. A surface flaw on otherwise sound glass can often be polished out. A crack, a chip, or a break in tempered glass cannot be repaired at all, because the damage compromises the whole panel and the fix is a new piece cut to the same size.
Scratches sit right on that line, and one test settles them. Run a fingernail across the scratch, and if the nail catches in the groove, the scratch is too deep to polish and the glass gets replaced. A shallower mark that the nail glides over comes out with cerium oxide and a felt pad, worked wet in small passes until the surface clears.
Tempered glass draws its own hard line. A chip on the edge of a shower panel or a railing looks minor, but tempered glass holds its strength in a locked balance of surface and core, and any break in that surface can take the whole panel down. A chipped or cracked tempered piece gets replaced, never patched.
When the Fix Is Hardware, Not Glass
A shower enclosure that leaks, drags, or sags usually has a hardware problem, and the glass is fine. The parts that move and seal wear out first, so a service call often ends with new seals or a hinge adjustment rather than a new panel. That fix costs a fraction of a replacement and takes a single visit.
A door that drips onto the floor points to the sweep and the seals along the edge. The clear strip at the bottom and the seals along the hinge side wear flat over years of use, so water finds the gap. Fresh seals and a new sweep close it, and the glass never comes off the wall.
A door that drags on the frame or no longer sits level points to the hinges. Frameless hinges carry the full weight of the glass, and solid brass or 316 stainless hinges last 15 to 25 years while cheaper zinc-alloy hardware fails sooner, with sag the usual sign. A technician resets or replaces the hinges, checks the swing, and brings the door back to level without touching the panel.
What a Professional Repair Visit Involves
Every repair opens with a diagnosis, since the visible symptom rarely names the part that failed. A technician checks the glass for scratches and chips, tests the door through its full swing, and inspects the seals, sweep, and hinges before quoting the work. That walkthrough sorts a hardware fix from a glass replacement in one visit.
A hardware repair usually finishes on the spot. The technician carries common seals, sweeps, and hinge parts, so a worn seal or a loose hinge gets handled the same day. A polish for a light scratch happens on site too, worked wet until the mark clears.
A replacement takes the longer path, because the glass has to be fabricated. The technician measures the opening, records the hardware layout, and orders the panel cut and tempered in-house to that measurement. The new glass drops into the existing hardware on a second visit, sized to fit without redrilling the wall.

Frequently Asked Questions
Can a scratch be polished out of glass?
A light surface scratch can be polished out with cerium oxide, but a deep one needs the glass replaced. The quick test is to drag a fingernail across the scratch: if the nail catches in the groove, the scratch is too deep to polish. A mark the nail glides over comes out with polishing on the wall.
Can you repair a cracked shower door?
No. Tempered glass cannot be repaired once it chips or cracks, because the damage compromises the whole panel and can lead to a full break. A cracked shower door, railing, or tabletop gets replaced with a new tempered piece cut to the same dimensions.
My shower door leaks. Do I need new glass?
Usually not. A leaking shower door almost always points to worn seals or a flattened sweep along the bottom, not a problem with the glass. New seals and a sweep close the gap in a single visit, and the panel stays on the wall.
Why won’t my shower door stay level?
A frameless door that drags or hangs crooked usually has loose or shifted hinges, which carry the full weight of the glass and move over time. A technician resets the hinges and rechecks the swing to bring the door back to level. The glass itself rarely needs to come off.
Do you repair or replace on the first visit?
A hardware fix like a worn seal, a sweep, or a loose hinge usually finishes on the first visit, since the technician carries those parts. A light scratch gets polished on site the same day. A glass replacement takes a second visit, because the new panel has to be measured, then cut and tempered in-house before it mounts.
