Insulation Removal in Hobe Sound

What has to come out

Hobe Sound is mainland Martin County, ZIP 33455, just north of Tequesta. Removal is a house attic that is wet, moldy, or nesting. Jupiter Island is the barrier island next to it. Both can share a ZIP. They are not the same street. The bridge matters.

What stays

A dry mainland ranch stays. Martin County is climate zone 2A, so the code floor is R-38, not the zone 1 floor of R-30. The install is still R-38. There is no Hobe Sound shop.

Getting the bags out

The shop is 17628 Brian Way, Jupiter, FL 33478. Call (561) 654-7698 and say which side of the bridge the house is on. 33455 is not 33469, and 33469 is not the Jupiter shop's ZIP.

How the day goes

Look
The hatch in Hobe Sound gets opened before a truck is promised. Depth, moisture, and whether the mess is the whole attic or one bay.
Protect
The rooms under the hatch get covered. The bags stay on the path that was agreed. A plaster or wood lid that is already soft stops the day.
Remove
Ruined fill is vacuumed into bags and hauled off. The deck should be visible where the bad fill was. Dry fill next to it is not taken just to make the attic look empty.
Next
Sanitizing only if the insulation was contaminated. Then the holes that are finally visible get sealed. Then new insulation to R-38. Those are not one price.

After the deck is bare

Foam is uncommon on the mainland ranches. It shows up when a roof is being brought inside. A vented attic, after removal, is still blown-in. Sanitizing is separate if the fill was contaminated.

The install that follows is blown-in insulation in Hobe Sound. Contaminated decks are attic sanitizing, a separate page. The contractor, separate from this tear-out, is the insulation contractor in Hobe Sound.

Questions

When do you remove insulation in Hobe Sound?

Is insulation removal included in a blown-in price?

No. Removal is its own price. A planning range for new fill does not include bagging out the old insulation. Sanitizing, if the fill was contaminated, is a second price. The new blow is a third.

Where is the shop for a Hobe Sound removal?

There is no shop in Hobe Sound. The crew comes from Cardinal Insulation of Jupiter at 17628 Brian Way, Jupiter, FL 33478. Call (561) 654-7698.

The attic numbers, not a brochure

The 2023 Florida Building Code, Energy Conservation, Table R402.1.2 sets a climate zone 1 ceiling at R-30 and a climate zone 2 ceiling at R-38. Cardinal installs R-38 and checks the inches. A Florida page that lists R-49 to R-60, or R-3.2 to R-3.8 per inch for both fiberglass and cellulose, is using a different book. Table R402.4.1.1 says air-permeable insulation shall not be used as the air seal.

Quotes are prepared by Russell Y, a building scientist, BPI certified, and certified to perform blower door testing. When the door is run, the result is air changes per hour at 50 pascals, the method in R402.4.1.2. That section limits new houses in climate zones 1 and 2 to 7 ACH50. An insulation job on an existing house is not automatically that test. We report the number only when we measured it.

Insulation numbers Cardinal uses against the Florida code
Item	Number	What it means
Zone 1 ceiling, Florida code	R-30 minimum	Palm Beach and Broward
Zone 2 ceiling, Florida code	R-38 minimum	Not R-49 and not R-60
What Cardinal installs	R-38, depth checked	Above the zone 1 floor
New blown fiberglass	About R-2.5 per inch	Not R-3.2 to R-3.8
Settled fiberglass	About R-2.2 per inch	4 inches is about R-9
New cellulose	About R-3.6 per inch	Denser. Still not an air seal
Open-cell foam	About R-3.6 per inch	A roof-deck product
Closed-cell foam	About R-6.5 per inch	2 inches is about R-13

The attics on this page

Hobe Sound is mainland Martin County, ZIP 33455, just north of Tequesta. Jupiter Island is the barrier island next to it. Both can share a ZIP. They are not the same street, and the bridge matters for the appointment.

Mainland houses get the Jupiter crew, an air seal, and R-38. There is no Hobe Sound shop. The shop is 17628 Brian Way, Jupiter, FL 33478. Call (754) 253-9607 and say which side of the bridge the house is on.

Foam is uncommon on the mainland ranches. It shows up when a roof is being brought inside. A vented attic is still blown-in. 33455 is not 33469, and 33469 is not the Jupiter shop's ZIP.

The code in Hobe Sound

Hobe Sound is in Martin County. Table R301.1 lists Martin County as climate zone 2A, not 1A. Table R402.1.2 sets the zone 2 ceiling minimum at R-38. That is the code floor here, not R-30. Hobe Sound does not publish a separate number. The Jupiter shop covers the call. There is no Hobe Sound pin.

Martin County is not in the High-Velocity Hurricane Zone. Section R806.2 of the 2023 Florida Building Code, Residential, sets the net free vent area at 1/150 of the attic. The exception is 1/300 only when 40 to 50 percent of that area is within 3 feet of the ridge and the rest is in the bottom third. Insulation cannot close the soffit. R806.3 requires at least 1 inch at the eave vent.

The county zone is Table R301.1. The Boca Raton worked example, including the vent math, is the building code page. Cardinal still installs a vented attic to R-38 and checks the depth.
