Windows in Charlotte fog, leak, and rattle for Piedmont reasons. Humidity and a long cooling season kill seals, in a NoDa loft house and in a Matthews bedroom. Older wood units in Elizabeth or Dilworth swell, stick, or draft when the rare ice night shows every gap. Newer vinyl fails at the lock, the balance, or the joint at the sill. Hail breaks glass. Lake wind finds a flange that a sheltered street never tests. This is not salt air, and it is not a mountain cabin. Say fog, soft wood, or broken glass.
Ask if the new unit leaves the old frame or opens the wall. An insert on a solid sill is a contained job. An insert on a sill that condensate has softened keeps the rot. Full-frame work should show the flashing and name who fixes casing inside and the skin outside. Two-story fronts on newer houses mean tall openings and interior finishes you do not want left unfinished. Ask who stands behind water that enters beside the frame. A glass promise often ends at the glass.
Street noise in the closer neighborhoods and an upstairs that will not cool are both real reasons to call. Ask for efficiency figures on the whole unit. A sticker is not a promise about comfort in a house with a hot attic and a long west wall. One hail-broken pane in a true frame can be glass only. A racked frame after a limb is a replacement. Flaking paint on an old sash should be mentioned before sanding. Count the openings so a single bath window does not become a whole elevation.
Hardware that quit and a sash that will not stay up are repairs, not a speech about new construction. Bay windows on bungalows are wider than a bedroom unit on a builder plan. Say which you have. If the house faces Lake Norman or Lake Wylie, say that the wind across the water is part of why the leak shows up in a storm and not on a calm day. Interior lots can skip that detail.
Bring the count and the symptom. Windows in Charlotte are a humidity, hail, and aging-frame problem in a city that is not the coast. Call the number on this page.
