Pinellas County Top-Rated Insulation Contractor
Serving Tampa, Brandon, Riverview, Plant City, and 18 more Hillsborough County communities — with the most detailed TECO rebate processing of any insulation contractor in the county. We service Hillsborough’s pre-1990 housing stock (median Tampa build year: 1985) where original R-11 attic insulation has settled to roughly 29% of current code.
As a TECO Energy Smart certified contractor, TLS handles the entire rebate process — pre-approval scheduling, paperwork, and the $0.15–$0.16/sq ft rebate applied directly to your invoice.

Hillsborough County's July high temperatures average 90.6°F, annual humidity stays above 85% in the morning for most of the year, and the average home was built in 1985 — to insulation standards that allowed R-11 in attics. Today's Florida Building Code minimum is R-38.
Research from the North American Insulation Manufacturers Association estimates approximately 90% of U.S. homes are under-insulated — and in Hillsborough County, where the median Tampa construction year is 1985, the proportion is likely higher.
Without adequate insulation, Hillsborough County attics regularly reach 150°F on July afternoons. Original 1980s R-11 insulation has typically settled to R-6 to R-9 — well below a third of today's R-38 minimum, forcing HVAC systems to work 2–3× harder.
In 11 years of inspecting Hillsborough County attics — from older Tampa bungalows to 1990s Brandon subdivisions — the single most consistent finding is original insulation that's been there since the home was built. Most of it is well below R-15 by now. Every one of those homes is losing money every month their AC runs.

What We Do
Every service performed by TLS’s in-house certified crew — no subcontractors. For Pinellas County coastal and barrier island properties, TLS uses only Johns Manville blown-in fiberglass, the only material we can warranty against salt-air degradation.
Hillsborough County falls under IECC Climate Zone 2A — the hot-humid classification that covers most of Florida. Under the Florida Building Code (FBC) 7th Edition, Section R402.1.2, attic/ceiling insulation in Zone 2 requires a minimum R-value of R-38 for homes with conditioned living space below an unconditioned attic.
The practical implication: any Hillsborough County home built before 1990 is almost certainly operating at roughly one-third of today's code requirement. New construction meets R-38 as a baseline, but most homes from the county's 1970s–1990s growth waves do not. This is the largest retrofit opportunity in the Tampa Bay insulation market.
TLS recommends R-49 as the optimal target for Hillsborough County attics — it qualifies for the full TECO Energy Smart rebate and delivers the highest long-term energy savings given Hillsborough County's 244 sunny days and extended cooling season.

From Tampa's historic inner-city neighborhoods to the fast-growing suburbs of Wesley Chapel and Land O' Lakes, and from coastal Apollo Beach to the agricultural communities of eastern Hillsborough — TLS has insulation covered for every Hillsborough County address. The same Johns Manville material standard, in-house TLS crews, and rebate processing applies regardless of which community you're in.
Historic neighborhoods and dense urban housing — Hyde Park, Seminole Heights, Ybor City, South Tampa, Westshore. Pre-1960s stock often operates below R-7. TLS's highest-volume Hillsborough sub-region.
Hillsborough's largest suburban growth corridor — 1970s–1980s build-out with typical R-11 to R-13 original insulation, now deeply degraded. Prime rebate territory.
Tampa Bay waterfront and retirement-community housing. Higher humidity exposure and homeowners actively managing energy bills — prime rebate candidates.
Wesley Chapel and the northern Pasco border corridor — one of Florida's fastest-growing suburban zones. 2000s–present builds, often close to but not fully at R-38 code.
Plant City's historic downtown stock (1940s–1960s) plus eastern agricultural-adjacent communities. Wide mix of housing eras, all sharing the same Zone 2A heat and humidity profile and qualifying for the same utility rebates.
TLS also serves neighboring counties across Tampa Bay and Southwest Florida.
Answers to the most common questions Hillsborough County homeowners ask before scheduling an attic inspection.
Hillsborough County is in IECC Climate Zone 2A. The Florida Building Code requires a minimum R-38 for attic insulation. TLS recommends R-49 as the optimal target — it delivers the maximum energy savings and qualifies for the full available utility rebate. Most Hillsborough County homes built before 1990 currently operate at R-11 to R-15, well below the R-38 code minimum.
Yes. Hillsborough County homeowners can qualify for Duke Energy and FPL utility rebates of up to $1,420, depending on the project scope and qualifying upgrades. Combined with the federal 25C tax credit (up to $1,200), the total incentive can substantially reduce out-of-pocket cost. TLS handles all rebate paperwork on your behalf and applies eligible rebates directly to your invoice.
Attic insulation in Hillsborough County typically ranges from $1,500 to $3,500 for a standard home, depending on attic size, existing insulation levels, and whether removal is needed. After utility rebates and federal 25C tax credits, many homeowners' net cost is $600–$1,000 lower than the pre-rebate price. See our attic insulation cost guide for the full breakdown.
For most Hillsborough County attics, blown-in fiberglass is the optimal choice. It fills irregular joist spacing common in pre-2000 Tampa Bay construction, resists Florida's humidity better than cellulose, and TLS's Johns Manville product carries a Lifetime Warranty against settling. For complete air-sealing applications in conditioned attics, closed-cell spray foam is recommended.
Blown-in fiberglass typically lasts 20–30 years before settling significantly impacts R-value — though Tampa Bay's higher-than-average humidity can accelerate this. In our 11+ years inspecting Hillsborough County homes, we consistently find that original 1980s insulation is performing at half or less of its installed R-value. Any home with original insulation from before 1995 should be inspected for performance and replacement.
Yes — if existing insulation is dry, undamaged, and free of pests or mold. Blown-in fiberglass can be added on top of most existing fiberglass materials. Do not add cellulose on top of fiberglass batts — the weight compresses the fiberglass and reduces total R-value. If existing insulation is wet, compacted, or contaminated, removal is required before new installation.
Yes.
