Repairs and problems
Shower doors and screens that no longer seal
The short answer
Enclosure leaks are almost always seals, alignment or the tray-to-frame joint. Glass rarely leaks; the fittings around it do.
Your questions answered
Can I reseal a whole enclosure?
Yes, replacing the perimeter silicone and seals is a routine maintenance job.
Why does water run outside the tray?
Usually a missing or worn drip strip at the bottom of the door, or a tray upstand detail that was never right.
How this is diagnosed
- 1
Magnetic strips and drip seals are consumables, and replacements are usually available by profile rather than by brand.
- 2
A door that has dropped on its rollers no longer meets the seal squarely, adjusting the rollers often solves what looks like a seal failure.

Second opinion on shower doors leaking
If you already have a quote or a design and something does not sit right, it is worth another set of eyes before work starts.
