Spray Foam Insulation in Crawfordville, FL

Spray Foam Insulation in Crawfordville mostly serves homes that are newer than the Tallahassee average and owned by families planning to stay. Crawfordville, the county seat of Wakulla County, grew from 3,702 residents in 2010 to 4,853 in 2020, about 31%, according to Wikipedia's census figures. Of 1,856 housing units counted, only 5.2% were vacant, and the median household income was $92,813. Owners here tend to invest in comfort and lower bills rather than quick fixes.

Flat, low and close to the coast

Crawfordville sits at an elevation of about 16 feet, on the flat pine woods between Tallahassee and Apalachee Bay. Tallahassee International Airport is about 18 miles north. Low, sandy ground near the Gulf means humid air almost year-round and, in some neighborhoods, homes built up on piers or stem walls. Raised floors lose comfort in two ways: summer air under the house makes the floor feel clammy, and winter cold fronts make it feel chilly. Closed-cell foam sprayed under the subfloor seals the floor from outside air, holds a high R-value per inch and does not soak up water.

Attics in newer homes

In the subdivisions built during Crawfordville's growth, the attic usually has blown insulation and the ducts run through it. The common gaps are at recessed lights, the attic access, top plates and the boots where ducts meet the ceiling. Air sealing those spots and topping up the insulation is often the lowest-cost improvement. If the ducts are long or leaky, open-cell foam under the roof deck brings them into a cooler, semi-conditioned space.

Code and recommended levels

Wakulla County, like Leon, is in IECC Climate Zone 2A. The 2023 Florida energy code's Zone 2 table lists R-38 for ceilings and R-13 for wood-frame walls. For an existing home, DOE suggests adding R-38 to R-49 where the attic already has 3 to 4 inches, and R-13 for an uninsulated floor.

Storm season

Being between the capital and the coast, Crawfordville gets wind and heavy rain from Gulf storms. Wet insulation after a roof leak should be removed once the roof is repaired. And a sealed house holds its temperature longer when power is out. We look for leaks and water stains on every visit and tell you about them before quoting any insulation.

Comparing bids in Wakulla County

When you collect quotes from insulation contractors, line them up area by area. For the attic, compare the air sealing included, the material, and the settled depth or R-value promised. For a raised floor, compare foam type and thickness, and whether the price includes removing old batts. HomeGuide's national figures put closed-cell foam at $3.00 to $5.00 per square foot installed and a crawl space foam job at $2,000 to $4,000, but access under low floors and the condition of what is there move the number a lot. Our written estimate after the visit is the price, and it spells out each of those items so the comparison is fair.

Garages and bonus rooms

Newer Crawfordville homes often have an attached garage, and some have a room above it. The floor of that room sits over unconditioned space, so it runs hot in summer and cool in winter. Spray foam in the floor framing and the kneewalls fixes both and seals out garage fumes.
