If your shower door leaks or leaves water puddles on the floor, you’re not alone. Even high-end frameless systems can develop leaks over time from worn sweeps, dried silicone, or uneven thresholds. The Glass Shop LLC offers free estimates and carries replacement parts for all models of frameless, semi-frameless, and framed shower doors — including bottom sweeps, strike seals, and magnetic kits — right here in Southwest Missouri.
Common Causes of Shower Door Leaks
Worn or missing door sweep – The clear vinyl at the bottom hardens or curls, allowing water to pass underneath.
Gaps in vertical seals or magnets – Shrinking or short seals leave openings between the door and fixed glass.
Cracked or missing silicone – Failed caulking at corners or thresholds lets water wick outside the enclosure.
Threshold slope issues – A flat or outward-sloping curb lets water pool and escape.
Spray angle and door alignment – Shower heads aimed directly at the door, plus out-of-square hinges, push water past the seals.
Clogged weep holes – On framed units, calcium buildup blocks drain paths designed to redirect splashed water.
Quick DIY Leak Checks
Close the door and look for daylight around the edges — light leaks mean water leaks.
Run the shower for 30 seconds and observe where water escapes.
If a business card slides easily under the door, your bottom sweep isn’t sealing.
Place a level on the threshold — it should pitch slightly inward (⅛"–¼").
Inspect silicone seams; yellowed, cracked, or moldy caulk means it’s time for re-sealing.
Fast Fixes and Parts We Stock
At The Glass Shop LLC, we stock and install:
Replacement bottom sweeps for ¼", 5/16", and ⅜" glass
Vertical seals, H-seals, and magnetic strips for frameless and semi-framed units

Professional re-siliconing and leak diagnostics
We can usually fix most leaks in a single visit. All quotes are free, and we’ll inspect your shower door’s slope, alignment, and seal condition at no cost.

When to Call a Professional
DIY fixes are great for minor leaks, but it’s time to call a pro if:
The curb slopes outward or is uneven.
The door doesn’t align due to bowed walls or out-of-square tile.
Glass is chipped or binding at hinges.
You’ve replaced seals but still see water escaping.
We can re-level the threshold, re-square panels, or replace damaged glass quickly — saving you hundreds over a full remodel.
Frameless vs. Semi-Frameless: What to Expect
Frameless shower doors look modern, but they rely on precision gaps and seals — not full metal frames. They’re designed to shed water efficiently, not contain every drop. If you prefer maximum water control, a semi-framed or return-panel setup may be a better option.
Our technicians can help you decide which design best fits your layout, style, and daily use.
Maintenance Tips to Prevent Future Leaks
Wipe seals and sweeps weekly to prevent calcium buildup.
Squeegee the door and threshold after each use.
Replace seals every 12–24 months depending on water hardness.
Avoid harsh cleaners that dry out silicone.
