Every autumn and winter storm season along the Black Sea coast exposes hidden installation and hardware flaws in apartments and villas across Batumi, Gonio, Kvariati, Makhinjauri, Chakvi, Tsikhisdziri, and Kobuleti. When sea gusts exceed 20–25 m/s, rain is driven horizontally against glass facades, causing puddles on floors, whistling drafts, and damp walls.
The service division of the Asel factory provides guaranteed aluminum and uPVC window repair across Batumi and all of Adjara. Here are the 5 technical causes of storm leaks and how we fix them.
1. Five Root Causes of Coastal Window Leaks & Drafts
| Storm Symptom | Root Engineering Cause | Asel Service Solution |
|---|---|---|
| Water overflowing from the bottom frame or glazing bead | Clogged drainage slots, missing non-return storm valves, or unsealed mullion T-joints | Milling & clearing drainage channels, installing one-way wind valves, sealing mullion joints |
| Loud wind whistling and cold drafts around the sash | Shrunken developer TPE seals and missing hinge-side locking points | Full perimeter replacement with elastic EPDM rubber gaskets + multi-point hardware upgrade |
| Damp plaster and black mold on side reveals and below the sill | UV-degraded exterior foam and unsealed exterior aluminum drip sill | Re-foaming and sealing the exterior perimeter with polyurethane facade elastomer |
| Sagging balcony door or jammed sliding portal | Worn hinges/rollers or shifted glass-unit setting blocks | Re-blocking the glass unit to restore sash diagonal geometry + 3D hinge/roller adjustment |
| Condensation or fogging inside the double-glazed unit | Depressurized perimeter butyl seal of the glass unit | Manufacturing and installing a new argon-filled Low-E glass unit within 2–3 days |

Frequently Asked Questions
Why does rainwater pool on my windowsill or floor during a windy storm in Batumi?
In 80% of apartments, storm leaks are caused by a combination of clogged or undersized weep drainage slots in the bottom frame, hardened contractor-grade gaskets, and weak locking compression. When Black Sea wind pressure exceeds 400–600 Pa, water is forced into the frame rebate and overflows indoors if exterior drainage valves are missing or blocked.
Can storm leaks and wind whistling be fixed without replacing the entire window?
Yes, provided the frame itself is structurally sound. In a single visit, an Asel service technician replaces hardened seals with marine-grade EPDM gaskets, upgrades the perimeter locking hardware, clears and valves the drainage channels, and reseals the exterior sill joint with polyurethane facade sealant.
