47% of Oklahoma City’s 306,366 housing units predate 1980, which in practice means aluminum frame single-pane that conducts heat straight through the frame. Heating runs 57% utility gas to 40% electric. Housing value sits at $231,300 against 306,366 units, which sets what a repair-or-replace decision looks like here.

What we get called for in Oklahoma City

Rotted wood sill under an older window

Water has been sitting there for a long time. The sill is the visible part; check the framing below before pricing a window.

Original single-pane aluminum

Poor performers, but replacement rarely pays back on energy savings alone in this climate. Comfort, noise and condensation are the honest reasons to do it.

Condensation on the inside in winter

Indoor humidity rather than window failure, particularly in a tighter house. Check a hygrometer before ordering windows.

Drafts at the frame rather than the sash

Air leaking around the frame means the rough opening was never sealed properly. That is fixable without replacing the window.

What this costs here

Sealing an entry point	$0-40 – do it yourself
Basic service call	$130-225
Typical repair	$360-1,050
Major repair or replacement	$1,900-6,500

Ranges reflect Oklahoma City-area labor against a $231,300 median. Two of these you can do yourself for nothing.

Check these first

• Ask what is included in the quote and what is billed separately.
• Ask for proof of liability insurance and any license your city requires.
• Photograph the condition before work starts. It settles disputes about what was there.
