Attic insulation in Delray Beach
East of I-95 the houses are often smaller CBS homes under barrel tile. The attic is vented, the hatch leaks, and three or four inches of old fill is doing almost nothing once the roof deck passes 130°.
West of Military Trail — 33445 and 33446 — the attics get bigger. Kings Point, Villages of Oriole, Delray Villas, The Hamlet, Addison Reserve. A lot of that fill went in during the 1970s and 80s and has settled to a thin blanket. If it's dry, the job is air sealing plus a top-up to R-38. If it's wet or rodent-damaged, it comes out first. That price is separate. Contaminated attics then get attic sanitizing.
The insulation company Delray houses call
Cardinal Insulation does the Delray Beach work from 955 S Congress Ave, Delray Beach, FL 33445. The Boca shop is 4263 NW 1st Ave, Boca Raton, FL 33431. Same crew that air-seals the attic, then blows fiberglass or cellulose to R-38. Spray foam only when the roof deck is the job. You get a depth check before we leave.
Pineapple Grove, Tropic Isle, Lake Ida, and the beach-side houses in 33444 are often smaller CBS homes. Kings Point, Villages of Oriole, Delray Villas, and The Hamlet in 33446 are the settled-batt attics. Both get the same standard. Boynton Beach, the next city north, is on its own insulation page.
Blown-in insulation in Delray Beach
This is the usual Delray job. Fiberglass or cellulose blown across the attic floor to an even R-38, after the penetrations are sealed. Fiberglass is the common top-up. Cellulose packs denser. We pick from what's already up there and how the attic is vented — not from a script.
A typical single-family attic in Delray Beach is one day. You get a depth check before we leave, not a guess from the truck.
Spray foam insulation in Delray Beach
Spray foam in Delray Beach is a roof-deck job: bonus rooms, hot roofs, and attics that should sit inside the conditioned house. Open-cell when you need depth in a rafter bay. Closed-cell when you need more R per inch. It is not a quiet substitute for blown-in on a vented attic floor.
Foam smells while it cures. Blown-in fiberglass and cellulose do not. If anyone in the house is sensitive, say so before we schedule a foam day.
Air sealing before the first bag
Delray's older can lights, bath fans, plumbing chases, and attic hatches leak conditioned air into a vented attic. Insulation over those holes just hides them. Every blown-in attic we do in Delray Beach starts with the seal.

R-38 in a Delray attic
Code in this climate is R-30 at the attic floor. We install blown-in to R-38. New fiberglass is about R-2.5 per inch, so a bare attic needs roughly 15 inches. Settled fiberglass already in the house is figured closer to R-2.2 per inch. The planner runs your inches. Set the city to Delray Beach and text the result — that message is a plan, not a bid.

Delray Beach insulation questions
Who does blown-in insulation in Delray Beach?
Cardinal Insulation, 955 S Congress Ave, Delray Beach, FL 33445. The Boca shop is 4263 NW 1st Ave. We air-seal the attic, then blow fiberglass or cellulose to R-38. Call or text (561) 654-7698.
What R-value should a Delray Beach attic be?
Florida's code minimum for these attics is R-30. Cardinal's blown-in standard in Delray Beach is R-38. Four inches of settled fiberglass is only about R-9. The gap is usually depth, plus leaks at the top plate and the hatch.
Do you insulate Kings Point and Villages of Oriole?
Yes. Kings Point, Villages of Oriole, Delray Villas, The Hamlet, and Addison Reserve are in the 33446 and west Delray run. A lot of those attics still have the original thin fill. If it's dry, we seal and top it up. If it's wet or full of rodent mess, it comes out first.
How much does attic insulation cost in Delray Beach?
A planning range, not a bid, comes from attic size and what's already up there. Use the attic planner and set the city to Delray Beach, then text it. Removal, a tight attic, and roof-deck foam are priced on their own.
Is spray foam the right job for a Delray house?
Usually no, if the attic stays vented. Blown-in on the floor is the bill-cutting job for most Delray houses. Spray foam belongs on the roof deck when a bonus room or a hot roof should sit inside the conditioned house. Foam has a cure smell. Blown-in does not. We will say which one the attic actually needs.
How long does blown-in insulation take in Delray Beach?
A typical single-family attic in Delray is one day, including air sealing. West Delray community attics are often straightforward. Older beach-side houses with odd framing and can lights take the same process, sometimes a longer seal.
Do you remove old insulation in Delray Beach?
If the fill is dry and just thin, we seal and top it up. If it is wet, moldy, or full of rodent mess, it comes out first. Removal is its own price. It is not buried inside a top-up number.
Which Delray Beach ZIP codes do you cover?
33444, 33445, 33446, 33483, and 33484. That runs from the beach side through downtown, west of I-95, Kings Point, and the Boca line. If you are on the city edge and the ZIP is not listed, call. We will say yes or no.
Will new attic insulation cut the electric bill?
A thin, leaky Delray attic makes the air conditioner cool air it already paid for. Air sealing plus an R-38 top-up is the usual fix. We do not promise a dollar amount. The bill depends on the unit, the ducts, and how the house is used.
