Storm history

An EF4 tornado struck Norwalk on March 5, 2022, according to Wikipedia, and more than 9 inches of rain fell on June 9-10, 2011. After storm repairs, many owners have walls and roofs opened up, which is the best time to add foam. Heavy rain is also a reason to check basements for seepage before insulating.

A town of owners

About 82.5% of Norwalk's 5,610 occupied homes are owner-occupied. Many owners are finishing basements; foam on the rim and walls before framing is a common request.

Homes around Lake Colchester and other low spots should be checked for damp basements first. We use closed-cell foam where dampness is possible.

Warren County climate zone

Warren County is in Climate Zone 5A on OpenEI's list, the same as the rest of the metro.

A typical Norwalk job

A 2008 two-story with an unfinished basement often gets closed-cell on the rim and walls before framing, attic sealing and a top-up, and foam on the garage ceiling under any room above. After storm repairs, we may also foam opened walls.

Costs

HomeGuide's national ranges put spray foam at $1.50 to $5.00 per square foot and an average attic job at $1,000 to $2,700. We price each area separately, and the written estimate is the price.

Checking basements after heavy rain

After a year like 2011, when more than 9 inches of rain fell in two days, many basements showed seepage. We look for stains and damp spots before insulating, and if water is coming in, it gets fixed first.
