Insulation Removal in Miami

What has to come out

Miami removal on this site is a house attic in Coconut Grove, Shenandoah, or Kendall. Brickell and the downtown towers do not have attics. A concrete slab under another unit is the wrong trade. A Grove house under tile comes out when the fill is soaked, moldy, or full of nests.

What stays

A dry Grove or Kendall attic is a seal and a blow to R-38. Kendall is the same rule with more square feet. There is no Miami shop and no Miami pin. The crew is based at 4263 NW 1st Ave. The drive is long. Call first.

Getting the bags out

Grove hatches and older wood lids are tight. Kendall ranch hatches are usually simpler and the volume is larger. The price is not one Miami number.

How the day goes

Look
The hatch in Miami 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

Miami-Dade is in the High-Velocity Hurricane Zone. That is a roofing rule. It does not change when attic fill comes out, and a removal is not a reroof. After the deck is clear, the new insulation is blown-in on a vented attic. Call (561) 654-7698.

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

Questions

When do you remove insulation in Miami?

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 Miami removal?

There is no shop in Miami. The crew comes from the Boca Raton shop at 4263 NW 1st Ave, Boca Raton, FL 33431. 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

The Miami attics this crew can blow are houses in Coconut Grove, Shenandoah, and Kendall. Brickell and the downtown towers do not have attics. A concrete slab under another unit is the wrong trade.

A Grove house under tile is the blown-in job: seal, then R-38. A Kendall ranch is the same job with more square feet. There is no Miami shop and no Miami pin. The crew is based at 4263 NW 1st Ave, and the drive is a long one.

Foam in Miami is a remodeled roof on a house. It is not a high-rise product. Say the neighborhood when you call. Coral Gables and the Grove are houses. The barrier-island towers are not.

The code in Miami

Miami is in Miami-Dade County, climate zone 1A. The ceiling minimum is R-30. Miami-Dade does not get a different attic R-value from Palm Beach on this table. There is no Miami shop on this site.

Miami-Dade is in the High-Velocity Hurricane Zone, the whole county. Roof assemblies and exterior openings need HVHZ product approval. A blown-in attic does not. The ceiling minimum stays R-30. 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.
