Moore is newer than most of Oklahoma – 39% of its 24,995 units predate 1980, which in practice means 90s vapor barriers installed on the wrong side of the wall. Heating runs 68% utility gas to 30% 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 Moore

Sump or drainage discharging next to the foundation

Extend the discharge well away from the wall. Pumping water out of the basement onto the ground beside it is a loop.

Window condensation running onto the sill

Failed seals or high indoor humidity. Either way the water pools on the sill and gets into the frame. Address the humidity first – it is cheaper than the windows.

Attic sheathing dark on the north slope

Ventilation shortfall. Warm moist air from the house condenses on cold sheathing. The fix is intake and exhaust, not surface treatment.

What this costs here

Hygrometer	$15 – buy one
Bath fan duct correction	$175-400
Crawlspace vapor barrier	$1,100-2,200
Mold inspection	$175-400
Remediation, single room	$850-2,200
Remediation, whole house	$6,500-15,000

Ranges reflect Moore-area labor against a $204,500 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.
