Attic Insulation
Blown-in fiberglass attic insulation, added to the depth your home needs, to even out hot and cold rooms and cut wasted heating and cooling.
Attic Insulation in Greenville, NC
Even a Greenville house built in the last thirty years can be getting by on the builder's minimum overhead. We seal the ceiling's leaks, then add blown-in insulation to one even depth, from the middle of the attic out to the eaves, in houses and townhouses alike. Send us the attic's size and we can usually quote it without a visit. The written estimate is free.
Insulating Greenville's Newer Attics
In a Greenville attic we add blown-in fiberglass over the existing layer, once the leaks in the ceiling are closed and baffles are in at the eaves. A layer that's wet or fouled comes out first. One that's merely old stays, and it counts toward the target.
Half the city's housing is newer than 1996, the median year built in the Census Bureau's 2020 to 2024 estimates, give or take two years. So the layer over a typical Greenville ceiling is a generation old or younger. The usual job is to find out how much is really up there, close what's been opened since, and bring the layer up to the target. If you can tell us the square footage and about how deep it is now, we can price it without coming out.

Measuring What a Greenville Attic Already Holds
ENERGY STAR's way to check is simple enough to try from the hatch. Look across the attic floor. If the joist tops are level with the insulation or stick up above it, more is needed. A ruler pushed down to the ceiling gives the depth, and multiplying the inches by 3, ENERGY STAR's rough figure for common insulation, gives you an estimate of the R-value.
ENERGY STAR then suggests adding insulation when the layer is more than 4 to 6 inches below the recommended level, or when the joists aren't buried. Take that reading in a few spots, because, as ENERGY STAR notes, an attic can be full in the middle and thin at the eaves. Send us the numbers with your square footage. The crew checks them again with you on install day.
How Much Insulation a Greenville Attic Needs
By the state code and by the 2021 national map alike, Pitt County is in climate zone 3. ENERGY STAR's figures for zone 3 are R-49 for an attic that starts out empty and R-38 added to one that holds 3 to 4 inches. Dry insulation already in place counts toward the total, and you don't pay for what's already there.
A new house only has to reach R-38 at the ceiling under the 2018 North Carolina Energy Conservation Code, which the Office of State Fire Marshal lists as in force, and the code lets R-30 stand where its full depth reaches over the wall tops at the eaves. That gap between the code and ENERGY STAR is why a Greenville house from the 1990s or 2000s can be up to code and still worth topping up.
Newer Greenville Houses: Where the Layer Runs Thin
About 73 percent of Greenville's housing units were built in 1980 or later, and the 2000s alone account for about 25 percent, the Census figures show. Attics that age share a few weak spots. The edges along the eaves are the hardest place to blow insulation to full depth, recessed lights need clearance, and insulation moved aside for ducts, an air handler or cable doesn't always get put back.
Unless a can light is rated IC, for insulated ceiling, ENERGY STAR says to hold insulation at least 3 inches away from it. Older cans that poke up into the attic should be covered and sealed before anything goes over them, the hiring guide adds. ENERGY STAR also notes that almost every home has a plumbing vent pipe passing through the attic, and that the chase around it should be sealed.
What to Look For
- Joists showing above the insulation near the hatch or the eaves
- Bare patches around ducts, the air handler or a walkway
- Can lights with no cover or clearance
- An unsealed gap around the plumbing vent pipe
Greenville Summers and Attic Ducts
The Greenville station's 1991 to 2020 normals from NOAA count about 53 days a year of 90 degrees or more and about 54 nights at freezing or below. Heating degree days, about 2,940, still edge out cooling degree days, about 1,920, and Pitt County is mixed-humid by the federal Building America climate guide. The attic has to slow heat going both ways.
Summer is when attic ducts matter most. ENERGY STAR's hiring guide says ducts lying on the attic floor should be sealed before insulation goes near them, and that the crew should be careful not to crush or step on them. We seal the joints and boots we can reach with mastic or metal tape. Anything crushed or disconnected gets left for an HVAC contractor, and we'll show it to you.

Greenville Attic Insulation Questions
What does it cost to insulate an attic in Greenville?
It depends on what's up there, but you don't have to wait on a visit to find out. The size of the attic floor sets most of the price, so we work from your square footage or your home's footprint. The rest turns on how far the current layer falls short of R-49 or R-38, how much sealing is needed around lights, pipes and the hatch, and whether old insulation has to be vacuumed out. The price comes in writing and costs nothing.
Will blown-in insulation settle?
Loose fill settles some after it goes in, which is why the FTC's R-value Rule makes the installer list both the thickness as installed and the minimum settled thickness on your receipt, along with the R-value, the area covered and the number of bags. That lets you check the settled depth against the R-value you were promised.
Should the air sealing be done before more insulation goes in?
Yes. ENERGY STAR tells homeowners to make sure the contractor seals the attic's holes and gaps before adding insulation, and to call another contractor if one won't. Sealing first is far easier while the old layer can still be pulled back, and the new insulation then covers a ceiling that isn't leaking air anymore.
Do you take out old attic insulation in Greenville?
When it has failed, yes, and only then. ENERGY STAR says existing insulation can stay unless it's wet or moldy, smells, or contains animal waste. For a layer that fails that test, the cause gets fixed first. Then it's vacuumed out, the bare ceiling is sealed and a new layer is blown in.
How do I get an attic estimate in Greenville?
