Pinellas Park has no Gulf frontage at all — it sits inland, wedged between St. Petersburg, Largo, Clearwater and Seminole. That spares it storm surge, but the city has a documented flooding history anyway, caused by low elevation between two large bodies of water and flat topography. It is a useful reminder that in Pinellas, being away from the beach is not the same as being dry.
A 1970s city
The housing here peaked sharply in the 1970s, with a strong 1980s wave behind it and a meaningful 1950s and 60s base in the older section. Those 1970s homes are now around fifty years old — built before Florida had a meaningful energy code, insulated to a standard that has since been overtaken twice, and settling the whole time.
Cross Bayou, the city’s largest area at around thirteen square miles, is 61 percent single-family detached and nearly 18 percent mobile homes. Elsewhere, Bonnie Bay is 1970s and 80s single-family with no mobile homes and high owner-occupancy. That split matters, because a block house and a manufactured home need completely different work — the first is an attic job, the second is usually a belly and duct job underneath.
The Department of Energy recommends R-49 to R-60 for an uninsulated attic in this climate zone. Almost nothing built here in the 1970s comes close, and that gap is measurable on your bill every month from March to November.
Duke Energy rebates
Pinellas County is Duke Energy Florida territory, and Duke pays considerably better than the utilities inland. It also pays on windows, which most Florida utilities do not.
- Attic insulation: up to $800, applied as an instant credit on the contractor’s invoice rather than a rebate you claim afterwards.
- Energy-efficient windows: up to $800. The glazing has to meet a hot-climate specification, and the rebate applies to east, west and south-facing windows — not north-facing, and not sliding glass doors or French doors.
- Duct test and repair: up to $450, also instant.
- Heat pump water heater: up to $800. Total programme value runs to roughly $3,800.
The order matters and it is where people lose the money. You must complete a free Home Energy Check — online, by phone or as a full in-home visit — and receive a qualifying recommendation before the work starts. You then have 24 months to complete it, and the installer has to be a Duke-approved contractor. Renters are eligible too. Duke completed 2,820 of these checks in Pinellas County in 2025, so it is a well-used programme, not a technicality.
The attic rebate is tiered by how bad your existing insulation is, with the target being R-38 — which is also what the building code prescribes for new construction in this climate zone. If your attic already measures well, you will not qualify, and we would rather tell you that at the estimate than after.
Inland, and still flooding
Pinellas Park’s flooding problem is structural rather than coastal — low ground between Tampa Bay and the Gulf, and almost no fall to drain it. Drainage infrastructure has improved things, but the underlying geography has not changed.
The 2024 season proved the point twice. Helene drove record surge into the coastal parts of the county — more than 18,500 structures across Pinellas and Hillsborough took major damage, and twelve people drowned in Pinellas. Milton, two weeks later, dropped nearly nineteen inches of rain on neighbouring St. Petersburg with over five inches in a single hour, and produced sustained 92 mph winds across the county.
Water that arrives as rainfall rather than surge ruins insulation just as thoroughly. Saturated fibreglass and cellulose compact, lose their R-value permanently and hold moisture against framing, and with overnight lows in the mid-70s for four months a closed cavity will not dry on its own. The EPA’s guidance is that porous materials wet for more than 48 hours generally have to be discarded. If your home took water and the insulation stayed in, it is still a problem.
Pinellas County applies a 49 percent rule on repairs — reach 49 percent of the structure’s value and the home must be brought up to current floodplain code. Worth establishing before work starts, not after.
Common questions
I have a manufactured home. Is it the same job?
No, and this is worth knowing before you call anyone. In a block or frame house the work is in the attic. In a manufactured home the heat and the air leakage are usually underneath — the belly board, the crawl area and the duct runs below the floor. It is a different scope with different materials, and a contractor who only quotes attics will either decline it or do the wrong thing. Cross Bayou alone is nearly 18 percent mobile homes, so we see a lot of these.
How can I tell if my attic is under-insulated without climbing up there?
Open the hatch and look across with a torch. If you can see the tops of the ceiling joists, you have roughly R-19 or less and you are well under code. If the insulation is level with the joists, you are around R-19 to R-30. It needs to sit several inches above them to be near the R-38 the code prescribes. On a 1970s Pinellas Park house the joists are usually visible.
Does Duke's window rebate cover every window in the house?
It does not. The rebate applies to east, west and south-facing windows — the ones taking direct sun — and not to north-facing openings. Sliding glass doors and French doors are excluded as well, which surprises people with a lanai slider they were counting on. The glazing also has to meet a hot-climate specification. We scope which of your openings actually qualify before quoting so there is no shortfall at the end.
My house took water in 2024 and nobody opened the walls. What should I do now?
Have it looked at. Water that arrives as rainfall ruins insulation just as thoroughly as surge does, and Milton put nearly nineteen inches on this part of the county. Saturated material compacts, loses its R-value permanently and holds moisture against the framing, and with overnight lows in the mid-70s for four months of the year a closed cavity does not dry out. It is also worth knowing that Pinellas County applies a 49 percent rule — if repairs reach 49 percent of the structure's value, the home has to be brought up to current floodplain code. Establish that before work starts, not halfway through.
Is there any rebate if I rent rather than own?
Yes. Duke's Home Energy Check and the associated rebates are open to renters as well as owners, which is unusual and not widely known. You will need the property owner's agreement for the work itself, but you are not excluded from the programme on the basis of tenancy.
Where we work
Across Pinellas Park — Cross Bayou and Cross Bayou Estates, Bonnie Bay, Villas of Bonnie Bay, Bonnie Glynn, Country Haven and the manufactured home communities including Golden Gate — and throughout the neighbouring parts of St. Petersburg, Largo and Seminole.
We install blown-in insulation and spray foam, handle insulation removal after flood or storm damage, and fit energy-efficient windows and storm damage repairs.
