Windows in Honolulu fail by corrosion and by wind-driven rain, and the south-shore salt is harder on hardware than people expect from a dry-looking week. Sliders seize. Jalousies stop closing. A valley window takes more shower and rots the sill while a leeward window chalks and leaks at the seal. Single-wall openings are in a thin wall. Framed openings can hide the leak a little longer and then stain the cavity.
If the sash will not open, the house has lost the trade-wind ventilation it was built around. Honolulu rooms that get sealed for cooling then sweat, and the sill stays wet enough for termites. Say if the complaint is a stuck window, a wet wall, or a room that will not dry. Sun fails seals on the bright elevations. Rain fails the ones that face the showers. Feel the wood.
An insert in a rusted frame is a short repair. Full replacement on a single-wall house has to respect a wall that is thin and often out of square. Ask how the sill sheds water where the overhang is small, which is common on these streets. A deep gap filled with a casual foam bead will not handle wind-driven rain for long. Count the bad units. The salty side is the place to start.
Photograph rusted hardware and stained boards before they are scraped, especially if a claim is open. Salt does not pause for a decision. A flange leak in a newer framed wall and a same-day drip on a single-wall board should not be written up as the same opening. Say which one you live in. If an ohana has its own rotten slider, keep that count separate from the main house.
Say how many openings face the south shore or a wet valley, and whether metal is rusted or wood is soft. Name the part of Honolulu. Mention single-wall if that is the wall. A sash that will not lock is not something to postpone. Call the number on this page.
