A leaking shower isn’t just annoying—it can cause water damage, mold growth, and costly repairs. Often, the culprit is a worn-out shower room sealing strip. These unsung heroes create watertight barriers between glass panels, doors, and frames. At Loire Hardware, we engineer premium sealing strips designed for frameless glass showers and enclosures. In this guide, you’ll learn how to diagnose, replace, and maintain sealing strips like a pro. 

Why Shower Sealing Strips Matter

Shower room sealing strips (also called shower seals or glass gaskets) serve three critical functions:

Water Containment: Prevent leaks onto bathroom floors.

Protection: Shield metal hardware like hinges and clamps from corrosion.

Noise Reduction: Minimize clattering when closing glass doors.

Cheap seals crack or shrink over time, but premium sealing strips from Loire Hardware—crafted from reinforced EPDM rubber and silicone—resist mold, UV damage, and extreme temperatures.

Signs Your Sealing Strip Needs Replacement

Watch for these red flags:

✘ Water pooling outside the shower

✘ Visible cracks, tears, or brittleness

✘ Mold or mildew trapped in the seal

✘ Doors sliding roughly or sticking

 

Ignoring these can damage your shower hardware and subfloor. Replace strips every 2–3 years or immediately if defects appear.

Step 1: Remove the Old Seal

Clean the Area: Wipe debris from the channel with a damp cloth.

Loosen the Seal: Gently pry one end with a flathead screwdriver.

Pull Steadily: Slowly pull the strip along its length (avoid tearing). If stuck, apply silicone lubricant.

Clear Residue: Scrape adhesive remnants with a utility knife (blade angled away from glass).

Step 2: Prepare the Channel

Deep Clean: Use mild detergent and water to degrease the track. Dry thoroughly.

Inspect Hardware: Check hinges or clamps for corrosion—replace if damaged.

Measure Twice: Confirm new strip length matches the old one.

Step 3: Install the New Sealing Strip

Lubricate: Apply silicone spray to the channel for easier insertion.

Start at One End: Press the strip firmly into the track’s corner.

Work Gradually: Use your thumbs to slide it along the channel, ensuring no twisting.

Seat the Edges: Ensure full contact with glass/metal surfaces.

Critical Check: Verify the seal creates even pressure against the glass.

Step 4: Test and Finish

Operate the Door: Open/close the shower door 5–10 times.

Water Test: Run water down the glass—check for leaks.

 Trim Excess: Cut overhanging ends with a utility knife.

Maintenance Tips for Longevity

Extend your seal’s life with these practices:

Monthly Cleaning: Wipe strips with vinegar/water (1:1 ratio) to prevent mold.

Lubricate Quarterly: Apply silicone spray to keep seals pliable.

Avoid Harsh Cleaners: Bleach or ammonia degrades rubber.

Check Alignment: Ensure doors don’t pinch seals when closing.
