Edmond is newer than most of Oklahoma – 26% of its 39,841 units predate 1980, which in practice means tight envelopes with poor make-up air, where humidity has nowhere to go. Heating runs 70% utility gas to 28% electric. 39% has been built since 2000, so this is really two housing markets in one place and what fails depends on which half you are in.

What we get called for in Edmond

Condensation on new windows

On a tight new build this usually indicates indoor humidity rather than window failure. Check a hygrometer before calling the window company.

Mold found during a home inspection

On a purchase, the question is scope and cause rather than presence. Get the moisture source identified before negotiating a price on the remediation.

Humidifier set high in winter

Over-humidifying a tight house causes condensation in the walls. Lower the setting as the outdoor temperature drops.

Growth in a new-build closet on an exterior wall

Often an insulation gap or a missed air seal. It is a warranty item if the build is recent enough.

What this costs here

Hygrometer	$15 – buy one
Bath fan duct correction	$200-475
Crawlspace vapor barrier	$1,400-2,800
Mold inspection	$200-475
Remediation, single room	$1,000-2,700
Remediation, whole house	$8,000-19,000

Ranges reflect Edmond-area labor against a $351,400 median. Two of these you can do yourself for nothing.

Check these first

• Check where your bathroom fan actually discharges. In the attic is not outside.
• Walk the perimeter after rain and look for soil sloping toward the wall.
• If growth returns after cleaning, stop cleaning and find the water.
