From Citrus Groves to Subdivisions
Spray Foam Insulation in Largo usually starts with an attic that has not been upgraded since the house was built. Largo was incorporated in 1905 and spent decades as a farm town of citrus, cattle and turpentine. After World War II it filled in fast: the census counted 1,547 people in 1950, 24,230 in 1970 and 57,958 in 1980. A large share of the houses we visit date from that run.
What those decades left behind
Homes from the 1960s and 1970s commonly have low-slope roofs, a few inches of fiberglass on the attic floor, and ductwork running through the attic. Some have additions with their own small attics, or Florida rooms with flat roofs and almost no insulation at all. Those rooms are often the hottest in the house. Closed-cell foam can insulate a low-slope roof from below in a few inches, while the main attic usually gets air sealing and blown-in insulation or roof deck foam, depending on where the ducts are.
Low ground and wet attics
Wikipedia notes that Largo's highest point is about 69 feet above sea level and that the McKay Creek basin in the southwest of the city is prone to flooding. Allen's Creek drains northeast Largo toward Tampa Bay. Water damage, whether from a roof leak, a storm or flooding in the lower walls, is a frequent reason we remove insulation here. Wet fiberglass and cellulose do not recover, so we pull it out once the source is fixed and the framing is dry.
A city of long-time residents
Largo's 2020 census counted 47,694 housing units with 15.1% vacant, and a median age of 50.8. Census QuickFacts puts the median owner-occupied value at $229,100 for 2020-2024, lower than much of North Pinellas. For owners on a budget, attic air sealing and blown-in insulation usually deliver the most comfort per dollar.
Weather extremes on record
The city's climate data on Wikipedia include a record high of 100F on July 5, 1995, and a record low of 22F on December 13, 1962, with about 49.58 inches of rain a year. The cold snaps are rare and brief; the summer heat is what insulation here is for.
Add-ons and Florida rooms
Many Largo houses from the 1960s and 1970s have been expanded with a Florida room, a converted carport or a rear addition, usually with a low-slope roof tied into the main house. These rooms tend to have the thinnest insulation and the most sun exposure. Where the ceiling cavity is shallow, closed-cell foam can reach a useful R-value in a few inches, while the main attic gets air sealing and loose fill. We price each part separately so you can do the hottest room first if the budget is limited.

Largo Questions
Can you insulate the flat roof over my Florida room?
Often, yes. If the ceiling can be opened or there is a small cavity, closed-cell foam gives a high R-value in a few inches. We look at how the roof is built and whether it has leaked before quoting.
Do you work on manufactured homes in Largo?
It depends on the home's construction and access. Note that Duke Energy Florida's posted rules exclude manufactured homes from its Home Energy Improvement program, so plan without that rebate.
My attic insulation got wet in a storm. Can it dry out?
Wet insulation rarely returns to full performance and can hold mildew. Once the roof or leak is fixed, we recommend removing the wet section and replacing it.
Which part of a Largo house should be insulated first?
Usually the main attic, since it covers the most ceiling area. If one add-on room is unbearable in summer, it can make sense to start there. We will tell you which gives more comfort per dollar.
