What has to come out

North Palm Beach hatches on the inlet side take weather. Removal is the job when that weather, or a rusted bath fan, has soaked the fill. The village is small. Lots are tighter than Palm Beach Gardens.

What stays

A dry attic is still an R-38 top-up. Salt air on the metal around a fan is not, by itself, a reason to vacuum the insulation. The fan still has to terminate outdoors.

Getting the bags out

There is no shop in the village. Jupiter is the closer listing, 17628 Brian Way, (561) 654-7698. Most of these houses are vented. The bags come down the hatch that already leaks weather, so the opening gets planned before the vacuum starts.

How the day goes

  1. Look

    The hatch in North Palm Beach gets opened before a truck is promised. Depth, moisture, and whether the mess is the whole attic or one bay.

  2. 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.

  3. 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.

  4. 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 belongs on a remodeled roof deck, not on the floor of a vented attic, and not as a substitute for taking wet fill out. After the deck is bare, the fan duct and the hatch are the repairs that keep the new fill dry.

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

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.

Measured against the Florida code

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.

The attics on this page

North Palm Beach is a small waterfront city between Lake Park and Juno Beach. Lots are tighter than Palm Beach Gardens. A few streets on the inlet side have hatches that take weather.

The attic work is the same R-38 standard. Access is the difference, and so is the salt air on the metal around the bath fans. A fan that has rusted open still has to terminate outdoors. There is no shop in the village. Jupiter is the closer listing.

Most of these houses are vented. Foam belongs on a remodeled roof deck, not on the floor of that vented attic. Call (754) 253-9607.

The code in North Palm Beach

North Palm Beach is in Palm Beach County. Table R301.1 of the 2023 Florida Building Code, Energy Conservation, lists Palm Beach County as climate zone 1A. Table R402.1.2 sets the zone 1 ceiling minimum at R-30. North Palm Beach does not publish its own attic R-value. The city enforces the Florida Building Code.

Palm Beach County is not in the High-Velocity Hurricane Zone. That zone is only Miami-Dade and Broward. Parts of the Palm Beach coast are still a wind-borne debris region, which is an opening-protection rule from the wind map, not an insulation number. 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.
