Windows in Raleigh live under oaks and in humidity, closer to coastal moisture than a western Piedmont city likes to admit. Fog between panes shows up in Mordecai bungalows and in north Raleigh bedrooms after years of cooling. Wood sashes inside the Beltline swell, stick, or draft when ice finds every gap the summer hid. Later vinyl fails at seals and locks. A tropical wind drives rain at a flange. Salt is not the attacker here. Water and age are.
Ask whether you are keeping the frame or opening the wall. Inserts work on a sound sill and preserve a mistake on a soft one. Full-frame work should name the flashing and who puts casing and exterior trim back on a house where the oaks shed directly onto the head. Old wavy glass, if you want it kept, has to be said early. A storm-racked frame will not be fixed with one pane. One rotten bath window is small. A front wall of original units under a willow oak is not.
Ask for whole-unit efficiency figures and do not accept a comfort fable. The attic, the canopy, and the system you already run decide the room. Flaking paint on a pre-war sash gets named before sanding. Count the openings. Hardware that will not lock and a rope that has snapped are repairs. Hail-broken glass happens and is less the local habit than a sash painted shut. If the leak appears only when rain blows from the east for a day, say that. It points at the joint, not the center of the glass.
Cameron Park porches and north-side builder elevations should not be ordered as if they were the same rough opening. Say which you have. Sandy eastern lots and clay western lots do not change the window, but the house age usually does. Mention the era in words, not a guessed renovation. Street trees also mean more debris in the sill track. That is maintenance until the wood is soft. Then it is a replacement conversation.
Bring a count and say fog, rot, or a leak in a blow. Windows in Raleigh are an oak-and-humidity problem in the capital, not a copy of the bigger city down the interstate. Call the number on this page.
