Once a year, give your shower enclosure 45 minutes of focused attention. That’s the difference between an enclosure that lasts 25 years and one that fails at year 7. Block out the time, work through the checklist below, and you’ll catch the small issues before they turn into the expensive ones.
Here’s what to inspect, in the order to do it.
Glass inspection (10 minutes)
Look at every glass panel under good light. Check for:
Chips on any edge. Even small chips on tempered glass edges can cause the panel to spontaneously shatter weeks or months later. If you see one, contact the supplier.
Hairline cracks anywhere on the panel. Hold a flashlight at an angle to catch them. Cracks get worse over time.
New surface scratches. Catching them early sometimes allows for polishing repair. Deep scratches usually mean replacement.
Mineral buildup or etching. Light buildup cleans off with white vinegar. Deep etching is permanent and means that spot can’t be fully restored.
Glass coating wear, if you have a water-repellent coating like EnduroShield applied. Coatings last 6 to 12 months and need reapplication.
Silicone seal inspection (10 minutes)
The most important section of the annual check. Press gently on the silicone with a plastic knife or your fingernail.
Flexible and rebounds when pressed: healthy. No action.
Hard, brittle, doesn’t rebound: degraded. Plan replacement within the next few months.
Yellowing or browning: early aging. Watch closely. Replacement may be needed within a year.
Cracks or gaps where silicone meets glass or wall: late-stage degradation. Replace now to prevent water damage.
Mildew that won’t wipe off with a mild bleach solution: silicone has absorbed the staining and needs replacement.
For Jamaican homes, plan proactive silicone replacement at the 3 to 5 year mark regardless of how it looks. Tropical humidity ages silicone faster than the seal often shows on the surface.
Hardware inspection (10 minutes)
Check every visible piece of hardware.
Hinges: tighten visible screws hand-tight with a screwdriver. Not a power tool. If a screw spins without tightening, the anchor has stripped and needs supplier repair.
Door handle: check it’s tight to the glass and doesn’t rotate freely. Tighten gently if loose.
Magnetic strip or door stop: confirm the door closes flush against it. A visible gap when closed means the door has drifted.
Brackets and clamps: visually inspect for loose mounting. Push gently to confirm nothing moves that shouldn’t.
Finish condition: look for bubbles in plating, discolouration, rough spots, or anywhere the finish has worn through. Once finish damage is visible, the piece is heading toward replacement.
Lubrication: a drop of silicone-based lubricant (not WD-40) on hinge pivots. Wipe excess.
Frame inspection if framed or semi-frameless (5 minutes)
For framed and semi-frameless enclosures, check the frame condition.
Anodized aluminum frame: should look the same as install day. White powdery spots (corrosion) means coastal-grade hardware would have been the better spec; the affected area needs cleaning or the frame piece needs replacement.
Powder-coated frame: look for chips in the coating that expose the aluminum underneath. Small chips can be touched up. Larger areas need professional refinishing or replacement.
Frame-to-wall connection: check the frame is still tight against the wall with no gaps. A small silicone-filled gap is normal. A growing gap is a problem.
Frame drainage holes, if your design has them: clear with a toothpick or small brush.
Track inspection if sliding (5 minutes)
For sliding doors, the bottom track needs annual deep cleaning.
Remove the door if your design allows. Some do, some don’t. Many sliding doors lift off the track when raised vertically.
Vacuum the track to clear hair and debris.
Scrub with a toothbrush and warm soapy water.
Pour white vinegar in the track. Leave it 10 minutes. Scrub again, rinse with clean water.
Confirm drainage holes are open. Poke through any blockage with a toothpick.
Re-hang the door if you removed it. Test the sliding action. It should be smooth.
Functional test (5 minutes)
After all the inspections and corrections, run the shower for 2 to 3 minutes with the door closed.
Check for any water making it past the door seal onto the bathroom floor. A few drops is normal. A stream is not.
For sliding doors, check that water in the track drains properly back into the shower.
Check that silicone seals don’t show water seeping behind them.
Open and close the door several times to confirm smooth action and proper alignment.
Documentation
Note the date you did the annual check. A simple note on the inside of a bathroom cabinet door, or a calendar reminder, makes it easy to remember when the next one is due.
If you replaced silicone, lubricated hinges, or made any other change, note that too. Year-to-year comparisons help spot trends. Hardware that needs tightening every 6 months is normal. Hardware that needs tightening every month points to a deeper issue.
When to call the supplier
After the annual check, contact the supplier if:
You found a glass chip or crack.
A hinge anchor is stripped.
Silicone needs full replacement (some homeowners do this themselves, others prefer the supplier).
Frame corrosion or finish damage is significant.
Track sliding action is rough even after deep cleaning.
Water made it past the door seal during the functional test.
A 1-hour service call addressing several of these at once is usually $100 to $250 USD and adds years to enclosure life.

Frequently asked questions
How long does an annual shower enclosure inspection take?
About 45 minutes for a typical residential enclosure. 10 minutes on glass inspection, 10 minutes on silicone, 10 minutes on hardware, 5 minutes on frame if applicable, 5 minutes on track if sliding, 5 minutes on functional testing. The 45-minute investment once a year is the difference between an enclosure that lasts 25 years and one that fails at year 7.
What time of year should I do the annual maintenance check?
Pick a memorable date and stick with it. Some homeowners use the anniversary of install. Others use start of year (January). Others use rainy season start. The date doesn’t matter; consistency does. A calendar reminder or note inside a bathroom cabinet helps you remember when the next check is due.
What’s the most important thing to check during annual maintenance?
Silicone seal condition. Press gently on the silicone with a fingernail. Healthy silicone is flexible and rebounds. Degraded silicone is hard or brittle. Yellowing or browning is early aging; cracks and pulling away from glass are late-stage failure. Silicone failure is the leading cause of shower enclosure water damage in Jamaican homes, so catching it early matters most.
Can I do the annual maintenance myself or should the supplier do it?
Most homeowners can do the inspection and basic corrections (tightening hand-tight, lubricating, cleaning) themselves. Call the supplier for things that need expertise: glass chips or cracks, stripped hinge anchors, full silicone replacement, frame corrosion, or rough track sliding action that cleaning didn’t fix. A combined service call addressing several issues at once is usually $100 to $250 USD.
Do I need to do the same maintenance for framed and frameless enclosures?
Mostly yes, but with differences. Frameless skips the frame inspection but adds more attention to hardware (which is more visible and structural). Framed adds frame inspection but the door alignment is less precision-dependent (the frame absorbs minor sag). Sliding doors of either type need the track inspection step. The overall time investment is similar across types.

If your annual check turned up issues worth a supplier visit, the contact page is the way to schedule. We’re set up for short maintenance calls as well as bigger jobs.

The 45-minute annual check is one of the best returns on time available in home maintenance. Skipping it for a few years is how homeowners end up with the four-figure repair bills. Doing it religiously is how the same enclosure lasts decades instead of a handful of years. Pick a date, put it on the calendar, and don’t skip it.
