Insulation removal in Boca Raton

Wet, moldy, or rodent-damaged fill comes out. Dry, thin fill stays and is topped to R-38. Removal is not included in a blown-in price. Call (561) 654-7698.

What has to come out

In Boca Raton the fill comes out when a roof leak has soaked the batts, when mold is growing on the insulation, or when droppings and nesting are packed into it. East Boca, 33432 and the shop ZIP 33431, is where the wet plaster lid shows up. West of I-95, 33433, 33496, and 33498, the usual ruined layer is a settled batt that a later leak turned into a mat.

What stays

A dry 1970s or 1980s batt stays. Four inches of dry fiberglass is about R-9. That is a top-up to R-38, not a tear-out. Tearing out dry fill to sell a bigger ticket is not the job. Century Village and other condominiums with no attic are not booked as a removal.

Getting the bags out

East Boca hatches are often in the garage and tight under barrel tile. The bags have to come down that same opening. A plaster ceiling under a soaked batt is fragile. We do not walk the joists and hope the lid holds. If the hatch cannot pass a bag, we say so before the truck is loaded.

How the day goes

  1. Look

    The hatch in Boca Raton 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

Once the deck is bare, the leak or the bath fan that caused the mess still has to be fixed. Sanitizing is a separate price, and only after the bad fill is gone. New blown-in is a third price. The shop for this work is 4263 NW 1st Ave, Boca Raton, FL 33431. Call (561) 654-7698.

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

Questions

When do you remove insulation in Boca Raton?

In Boca Raton the fill comes out when a roof leak has soaked the batts, when mold is growing on the insulation, or when droppings and nesting are packed into it. East Boca, 33432 and the shop ZIP 33431, is where the wet plaster lid shows up. West of I-95, 33433, 33496, and 33498, the usual ruined layer is a settled batt that a later leak turned into a mat.

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.

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

The Boca listing is one shop: 4263 NW 1st Ave, Boca Raton, FL 33431. The shop ZIP is 33431, downtown west of the Intracoastal, older blocks, barrel tile, and hatches in garages. 33432 is the beach side, smaller lots, tighter access. 33486 and 33487 are the north end toward Delray.

33434 is Military Trail and Century Village. A lot of Century Village is condominiums. A unit with no attic is not booked as a blow. 33433 is west of I-95, Town Center and Boca Del Mar, 1970s and 1980s fill that has settled. 33496 and 33498 are the west attics, wider, and they are written on the West Boca page so this page stays the shop.

Blown-in insulation is the first service. The sequence is the air seal, the baffles, then fiberglass or cellulose to an even R-38. Cellulose only if the ceiling can carry the weight. Russell Y writes the quote. He is a building scientist, BPI certified, and certified to run a blower door. The door number is reported only when the door was run.

The code in Boca Raton

Boca Raton 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. Boca Raton 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.
