Shower door leaking onto your bathroom floor? We diagnose the cause and fix it -- seal replacement, realignment, hardware adjustment, or full replacement across Washington DC, Virginia, and Maryland.
Water on the bathroom floor causes mold, subfloor damage, and is a slip hazard. Most leaks are repaired in a single visit. We test with running water before we leave to verify the fix.

Leak Anatomy
Shower door leaks originate from four primary failure points. Understanding where the water is escaping is the first step to a permanent fix.
The flexible rubber or PVC strip along the bottom of the door is the most common failure point. When it cracks or hardens, water flows freely under the door onto your bathroom floor. Sweeps degrade faster in hard water areas like the DMV.
Where the door panel meets a fixed glass panel, a seal strip or magnetic strip creates the water barrier. When this seal loses compression or pulls away, water drips through the junction every time the shower runs.
Silicone caulk along the wall-to-glass junction breaks down from moisture, temperature swings, and cleaning chemicals. Once it cracks or separates, water seeps behind the enclosure and into the wall cavity where it causes hidden damage.
Heavy glass doors stress hinges over time. As hinges loosen, the door sags and no longer aligns with the seals on all sides. Even a 2mm shift creates visible gaps where water escapes, especially on the hinge side and bottom corners.
Common Causes
Every leak has a cause. We identify the specific problem so the repair addresses the root issue, not just the symptom.
The flexible seal along the bottom of the shower door has hardened, cracked, or worn away. This is the most common cause of shower door leaks.
The shower door is not hanging plumb or making proper contact with seals on all sides. Hinges loosen over time, pivot points wear,
The vertical seal strips along the sides of the door (jamb seals) are worn, torn, or missing. On framed doors, the frame channel seal may be deteriorated.
The silicone caulk at the junction of the glass, frame, and wall has deteriorated, cracked, or separated. Water seeps behind the frame,
Loose hinges, worn roller assemblies, bent tracks, corroded clips, and failing brackets all contribute to door misalignment and seal gaps.
Some shower door configurations are inherently more prone to leaks due to their design. Door openings that face the shower spray directly,

Door Configurations
Different shower door designs have different leak vulnerabilities. We repair all four common configurations found in DMV homes.
Bottom sweep, hinge-side gaps, panel junction seals. Heavy glass stresses hinges over time causing sag and misalignment. Requires precise hinge adjustment and proper sweep profile selection.
Bottom track channels, panel overlap seals, wall-to-frame junction. Tracks collect mineral deposits and corrode. Rollers wear causing panels to sit unevenly. Track cleaning and roller replacement are common fixes.
Frame-to-wall caulk, bottom sweep, hinge-side frame seal. Frame channels trap water that accelerates corrosion. Deteriorated frame seals are harder to match than frameless seals due to proprietary profiles.
Angled panel junctions, corner seals, wall-to-panel connections. The multiple angled joints create more potential leak points than rectangular enclosures. Precise seal profiles are critical at each angle change.
Solutions
We remove the old, worn seals and sweeps and install new ones that match your door type and dimensions. New seals are flexible, water-resistant,
We adjust hinges, pivot points, and mounting hardware to restore the door to its correct hanging position.
Worn, corroded, or broken hinges, rollers, guides, clips, and brackets are replaced with new hardware that matches your door specifications. New hardware restores proper door operation and alignment, eliminating gaps and seal failures caused by worn components.
We remove all old silicone caulk, clean the surfaces, and apply new high-quality silicone sealant at all glass-to-wall, frame-to-wall, and glass-to-frame junctions. Proper silicone application requires clean, dry surfaces and correct bead thickness for lasting water protection.
We install a drip rail channel on the outer face of the shower door to redirect water that runs down the outside of the glass back into the shower. Drip rails are particularly effective on frameless doors where the glass edge extends beyond the threshold.
When the door is beyond repair -- severely corroded frame, scratched or chipped glass, obsolete hardware, or fundamentally flawed design -- full replacement is the best option. We install new shower doors engineered for reliable water containment with modern sealing systems.
How We Work
We identify exactly where and why water is escaping. We test with running water, inspect all seals and hardware, check door alignment, and examine caulk condition. Knowing the specific cause ensures we fix the right problem and the leak does not return.
Based on the diagnosis, we recommend the specific repairs needed -- seal replacement, realignment, hardware replacement, recaulking, or a combination. You receive a clear explanation and a written estimate before any work begins.
We complete the repairs using high-quality replacement parts matched to your door type. Seals are replaced, hardware is adjusted or replaced, caulk is reapplied, and the door is tested with running water to verify the leak is eliminated.
After completing repairs, we run the shower at full pressure for several minutes and check every potential leak point. We verify that water stays inside the shower and drains properly. You see the results before we leave.
Every day your shower door leaks is another day of moisture seeping into your floor. Call for a free diagnosis and repair estimate. Most leaks are fixed in one visit.
Prevention
Run your finger along the bottom sweep and side seals once a month. If you feel cracks, hard spots, or gaps, the seal is failing. Replacing seals proactively before they leak completely prevents water damage to your bathroom floor and subfloor.
Hard water mineral deposits build up on seals, hinges, and tracks, causing premature deterioration. Wipe seals and hardware with white vinegar monthly to dissolve mineral buildup. DMV water is moderately hard, making regular cleaning especially important.
Open and close your shower door slowly, watching how it contacts the seals on all sides. If you see daylight between the door and any seal, the door is misaligned and will eventually leak. Address alignment issues before they cause water damage.
Using a squeegee on the glass after every shower directs water into the drain rather than sitting on seals and hardware. Less standing water means less mineral deposit buildup, less mold on seals, and longer seal life. A simple daily habit that extends your door lifespan.
Abrasive cleaners, bleach, and ammonia-based products degrade silicone caulk and rubber seals. Use mild soap, vinegar, or cleaners specifically designed for glass shower doors. Harsh chemicals accelerate seal failure and cause premature leaking.
Schedule an annual shower door inspection with us. We check all seals, hardware, alignment, and caulk condition. Catching small issues annually prevents expensive water damage repairs. Consider it the same as annual HVAC or plumbing maintenance.
