Spray Foam Insulation in Cape Coral, FL

Spray Foam Insulation in Cape Coral serves a city built around water. Cape Coral has more than 400 miles of canals, more than any other city on earth according to Wikipedia, and sits only about 10 feet above sea level. It is overwhelmingly single-family: Point2Homes' census summary shows about 79% of units are detached houses and owners occupy about 77% of occupied homes.

Built mostly since 1980

The median build year is 2000, and about a third of homes date from 2000 to 2009. Houses from the 1980s and 1990s often have attic insulation that has thinned and compressed over the decades. Newer ones usually have more, but nearly all have the air handler and ducts in the attic, and many rooms at the ends of long duct runs struggle in August.

Low ground and storms

At about 10 feet of elevation with canals everywhere, Cape Coral took surge and wind from Hurricane Ian in 2022. Many roofs were replaced, and attic insulation was soaked or crushed in places. A newer roof makes a sealed attic with open-cell foam under the deck more practical.

What we usually recommend

• Seal the ceiling and ducts, then blow fiberglass to R-38 or R-49
• Price roof deck foam where the roof is newer and ducts are extensive
• Remove and replace storm-damaged attic insulation
• Insulate garage ceilings and enclosed lanais

Costs

HomeGuide lists a blown-in attic at $900 to $3,600 and roof deck foam at $1,500 to $9,000 nationally. The written estimate is your price.

Bonus rooms and two-story homes

Not every Cape Coral home is a single-story ranch. Two-story homes and homes with a room over the garage often have one area that never cools, usually because of thin insulation around kneewalls and sloped ceilings, or a long duct run through the hottest part of the attic. Sealing and foaming those surfaces, and sealing the duct run, usually fixes it.
