Attic Insulation in Hollywood - Same-Day Service, Done Right the First Time

Insulation in Hollywood, FL

Spray foam insulation in Hollywood, FL is the most common retrofit we install in the city’s mid-century concrete block homes, where attics routinely hit 150°F and the air handler sits right in the middle of that heat. Most full attic spray foam jobs in Hollywood run between $4,200 and $8,900 depending on square footage and foam type. If your home was built between 1950 and 1980, call (218) 261-7714 for a written price with a blower-door reading before and after.

Why Hollywood Homes Are Different

Hollywood’s housing stock is a product of the post-WWII building boom: dense rows of CBS (concrete block structure) homes from roughly 1950 through 1980, built before Florida’s energy codes meant anything. These houses went up with empty wall cavities and a thin dusting of attic insulation at best. The concrete block walls have no retrofit-friendly stud cavity, so wall insulation options in Hollywood are limited mostly to injection foam or exterior approaches. The real action is in the attic.

Hollywood sits in IECC Climate Zone 1A, the most extreme cooling-load designation in the continental US. In July and August, attic cavities in these low-pitched CBS homes regularly reach 150-160°F. The air handler and supply ducts are almost always up there too. That means conditioned air passes through ductwork baking in 150°F+ air before it ever reaches a bedroom vent. Insulation strategy in Hollywood isn’t about staying warm in winter. It’s about keeping the heat out of the attic so the A/C doesn’t work against itself.

Salt-laden Atlantic air adds another layer. Fiberglass batt insulation degrades faster here than a few miles inland, and flat or low-slope roofs common in Hollywood leave less attic depth to work with. Those two factors push more homeowners toward closed-cell spray foam on the roofline or blown-in top-ups paired with air sealing, rather than simple batt replacement.

Our Main Hollywood Services

Most Hollywood homeowners call us about one of two things: an attic that’s too hot and a floor system that’s pulling humid air into the living space. Both have dedicated Hollywood pages below.

Attic Insulation in Hollywood

In Hollywood’s CBS homes, attic insulation is the single highest-impact retrofit available. The shallow attic cavities above these low-pitched roofs leave less room for insulation than a typical suburban truss attic, so we almost always pair air sealing with blown-in or spray foam rather than laying batts. Before any insulation goes in, we seal top plates, can lights, and wire penetrations, then run a blower-door test so you can see the before-and-after numbers. The full scope, including which materials we’ll use from Owens Corning or Knauf, is written down before work starts. Attic Insulation in Hollywood

Crawl Space Encapsulation & Vapor Barrier in Hollywood

Homes nearer Hollywood Beach and the historic downtown corridor sit on moisture-heavy soil that pushes humid air up through the floor system year-round. Encapsulation seals the crawl space with a vapor barrier and dehumidification, cutting the moisture load on the home’s insulation and the air handler. For wood-frame homes in these older Hollywood neighborhoods, this is often the difference between mold-prone fiberglass and insulation that stays dry. Crawl Space Encapsulation & Vapor Barrier in Hollywood

Spray Foam Insulation in Hollywood

Spray foam insulation in Hollywood solves a problem most homeowners feel but can’t name: the attic is 40 degrees hotter than the living room, and the A/C never cycles off. In CBS homes built from the 1950s through the 1970s, the roofline and attic floor have no meaningful insulation, so radiant heat pours through the roof deck into the shallow attic cavity where the ductwork lives. Closed-cell foam applied to the roofline moves the thermal boundary to the roof itself, pulling ducts and air handlers inside the conditioned envelope. Our crews install Spray Foam Insulation in Hollywood with before-and-after blower-door readings on every applicable job.

Open-Cell Spray Foam

Signs you need it

Your upstairs rooms run 8-12 degrees warmer than the thermostat setting in summer, and the attic feels like a sauna even after sunset.

What it costs in Hollywood

Open-cell spray foam in Hollywood attics typically costs $1.90-$3.30 per board foot, with full attic jobs running $3,800-$7,600.

How we do it

We air-seal the attic floor first, then spray open-cell foam to the roofline at code-required depth, and finish with a blower-door reading before and after.

Closed-Cell Spray Foam

Signs you need it

Salt-air humidity has made your fiberglass batts sag or stain, or condensation forms on the underside of the roof deck in summer.

What it costs in Hollywood

Closed-cell spray foam in Hollywood runs $3.10-$5.10 per board foot, and typical roofline applications total $6,400-$12,800.

How we do it

We prep the roofline, apply closed-cell foam to the specified depth, and document the finished mil thickness with photos as part of your job record.

What Spray Foam Insulation Costs in Hollywood

Can spray foam be applied over old insulation in a Hollywood attic?

No. We remove the existing insulation first. Spray foam needs direct contact with the roof deck or attic floor to bond correctly, and in Hollywood’s humid climate, trapping degraded fiberglass under foam creates a moisture problem.

How long does spray foam take to cure in Hollywood’s humidity?

Closed-cell foam is usable within 24 hours. The salt-heavy air near the coast doesn’t slow curing, but it does make proper ventilation during application more important. Call (218) 261-7714 for specifics on your roofline.

Blown-In Insulation in Hollywood

Blown-in insulation in Hollywood is the most cost-effective retrofit for the shallow, flat-roofed attics on mid-century CBS homes. The loose-fill material settles into the irregular cavities above these low-pitched roofs, covering the duct chases and top plates that batt insulation leaves exposed. In a Climate Zone 1A market, blown-in fiberglass or cellulose works best when the attic floor is air-sealed first, which is how every Hollywood job starts. Most blown-in jobs in Hollywood run $2,300-$4,700 depending on depth and square footage. We source materials from Owens Corning and Knauf, and every job gets a written scope before work starts. Blown-In Insulation is our default recommendation for Hollywood attics under 1,200 sq ft with existing ductwork on the floor.

Blown-In Cellulose

Signs you need it

Your attic insulation has settled to below the top of the ceiling joists, so the attic floor reads hotter than the living room ceiling on a thermal scan.

What it costs in Hollywood

Blown-in cellulose top-ups in Hollywood attics run $2.00-$2.75 per square foot at R-38 depth.

How we do it

We air-seal penetrations, install depth markers, and blow cellulose to the specified R-value using hose-fed equipment from the truck.

Blown-In Fiberglass

Signs you need it

You want a loose-fill option that won’t hold moisture from Hollywood’s salt-humid air and won’t settle as dramatically as older cellulose.

What it costs in Hollywood

Blown-in fiberglass in Hollywood attics typically costs $1.85-$2.60 per square foot at R-38.

How we do it

We seal the attic floor, mark target depth, and blow fiberglass to the specified R-value, then photograph the finished coverage for your record.

What Blown-In Insulation Costs in Hollywood

Is blown-in insulation worth it in a Hollywood CBS home?

Yes. CBS walls can’t easily be retrofitted, so the attic is the one place you can add meaningful R-value. On a 1,500 sq ft Hollywood home, an R-38 attic can cut cooling load by 15-20%.

Will blown-in insulation get wet from Hollywood’s coastal humidity?

Only if the attic isn’t air-sealed or the roof has a leak. The bigger risk is open vents pulling salt-heavy air through the attic. We check ventilation before recommending a blown-in product.

Radiant Barrier Installation in Hollywood

Radiant barrier installation in Hollywood attacks the city’s biggest thermal problem directly: radiant heat from a roof deck baking at 150-160°F above the attic. In a CBS home with a low-pitched roof, that radiation transfers to the attic floor and the ductwork sitting on it, which is why Hollywood attics run so much hotter than the outdoor air. A radiant barrier stapled to the underside of the rafters reflects most of that heat back toward the roof. In Hollywood’s climate, Radiant Barrier Installation works best paired with air sealing, and most homes see attic temperatures drop 20-30°F. Typical radiant barrier jobs in Hollywood run $1,200-$2,800 depending on attic size and access.

Attic Radiant Barrier

Signs you need it

Your attic hits 150°F+ in the afternoon even though the outdoor temperature is 88°F, and the A/C runs in 12-minute cycles all afternoon.

What it costs in Hollywood

A radiant barrier for a Hollywood attic typically costs $1,400-$2,700 depending on roof geometry and access.

How we do it

We staple the foil to the underside of the rafters, maintain a 1-inch air gap, and photograph the completed coverage before we leave.

Radiant Barrier Foil

Signs you need it

You want the lowest-cost way to drop attic temperature before committing to re-insulating the whole attic floor.

What it costs in Hollywood

Foil-only radiant barrier for a smaller Hollywood attic (under 1,000 sq ft) runs $1,200-$2,100.

How we do it

We map the rafter layout, cut foil panels to span the full bay width, and mechanically fasten them with staples, keeping the reflective surface clean.

What Radiant Barrier Installation Costs in Hollywood

Does a radiant barrier work in a Hollywood climate where it’s hot year-round?

Yes, it works best in exactly this climate. Radiant barriers are most effective where cooling dominates and attic temperatures spike, which is Hollywood’s entire summer. The key is the air gap and clean installation.

Can a radiant barrier be added to a flat-roof Hollywood home?

It depends on access. Many Hollywood CBS homes have very shallow attic space, which makes full rafter coverage harder. We evaluate the roof geometry and access clearance before recommending this option.

Insulation Removal & Replacement in Hollywood

Insulation removal in Hollywood is usually triggered by one of three conditions: rodent contamination, moisture damage from the salt-humid Atlantic air, or a failed install from years ago that’s now compressed to near zero R-value. Older Hollywood homes, especially wood-frame houses near the beach, hold moisture longer, and degraded fiberglass sagging between joists is a common find. We remove and replace insulation in Hollywood before air-sealing and new insulation go in, which makes the final blower-door reading meaningful. Full removal and replacement in a 1,200-1,800 sq ft Hollywood attic runs $2,900-$5,400. Our crews Insulation Removal & Replacement is documented with photos before, during, and after.

Attic Insulation Removal

Signs you need it

The existing insulation is matted, compressed below the joists, or visibly discolored from years of salt-air exposure and dust accumulation.

What it costs in Hollywood

Attic insulation removal in Hollywood runs $1,500-$2,900 for a typical 1,200-1,500 sq ft attic.

How we do it

We use a commercial HEPA-filtered vacuum system to remove the old material down to the joists, then photograph the naked attic floor before new insulation goes in.

Contaminated Insulation Removal

Signs you need it

You’ve seen rodent droppings in the attic, or a raccoon or rat has nested in the fiberglass, and the insulation smells when the A/C runs.

What it costs in Hollywood

Contaminated insulation removal in Hollywood runs $2,100-$3,800 depending on the extent of the contamination and attic size.

How we do it

We bag and remove the contaminated material, sanitize the attic floor, and apply a biocidal treatment before any new insulation is installed.

What Insulation Removal & Replacement Costs in Hollywood

Can’t I just blow new insulation over the old stuff in my Hollywood attic?

Sometimes, but not if the old material is wet, rodent-contaminated, or compressed below R-value. In Hollywood’s humid air, bundling new insulation over degraded fiberglass can trap moisture. We’ll tell you which path is right for your attic.

How long does insulation removal take in a Hollywood home?

Most 1,500 sq ft Hollywood attics are fully removed in one day, with replacement insulation following the next day or same day depending on the product. The whole job typically wraps in two days.

Attic Air Sealing in Hollywood

Attic air sealing in Hollywood is the step that makes every other insulation upgrade work. In a CBS home, the attic floor is pierced by top plates, wire penetrations, can lights, and duct boots, all of which leak conditioned air into the attic and pull 150°F attic air back into the living space. Sealing those leaks before adding insulation is how you actually lower cooling bills in Hollywood’s Climate Zone 1A summers. Every air sealing job we do in Hollywood starts with a blower-door test, so you can see the measured leak rate before and after. Typical air sealing jobs in Hollywood run $900-$2,000. Our Attic Air Sealing work is a prerequisite, not an upsell: we will not blow insulation over an unsealed attic floor.

Attic Floor Air Sealing

Signs you need it

Your A/C bill spikes in summer even though the thermostat setting hasn’t changed, and rooms farthest from the air handler never quite cool down.

What it costs in Hollywood

Attic floor air sealing in Hollywood runs $900-$1,700 for a typical 1,200-1,800 sq ft attic.

How we do it

We seal the attic floor penetrations with foam and caulk, then run a blower-door test to verify the reduction in CFM50.

Can Light & Duct Boot Sealing

Signs you need it

Your recessed can lights are warm to the touch, or you feel a draft at the ceiling registers when the A/C cycles off.

What it costs in Hollywood

Can light and duct boot sealing in Hollywood runs $250-$550 depending on the number of fixtures and boots.

How we do it

We seal each can light with a fire-rated cover and seal the gap between each duct boot and the drywall with mastic or foam.

What Attic Air Sealing Costs in Hollywood

How do I know if my Hollywood attic is leaking air?

The blower-door test gives you a single number: CFM50, the cubic feet of air per minute leaking through the building envelope at 50 pascals of pressure. We measure before and after, and you get the numbers in writing.

Does air sealing really matter in a home with no wall insulation?

Yes. In CBS walls there’s no cavity to seal, so the attic floor is the largest leak surface by far. Sealing it can reduce total air leakage by 30-50%, which is why we do it before any insulation goes in.

Wall Insulation in Hollywood

Wall insulation in Hollywood is a different problem than in most cities, because the dominant housing stock is CBS, concrete block structure. The walls are solid masonry with no stud cavity, so you can’t just blow insulation into a wall void the way you would in a wood-frame home. For Hollywood’s CBS houses, the practical options are injection foam into the block cores or an exterior insulation approach, and both have cost implications. For the older wood-frame homes near Hollywood Beach and the historic district, drill-and-fill dense-pack cellulose or injection foam into the stud bays is the standard approach. Wall insulation projects in Hollywood run $3,500-$11,000 depending on wall type and square footage. Our Wall Insulation work always includes a written scope for the specific wall assembly, because we won’t guess at a building you live in.

Injection Foam Wall Insulation

Signs you need it

Your exterior walls radiate heat into the house late into the evening, and rooms with west-facing walls run noticeably hotter in the afternoon.

What it costs in Hollywood

Injection foam for CBS block walls in Hollywood runs $4,500-$8,900 depending on wall area and access.

How we do it

We drill injection ports into the mortar joints, pump foam into the block cores, and patch the ports to match the existing finish.

Drill & Fill Wall Insulation

Signs you need it

Your wood-frame home near the historic district or beach has no insulation in the wall cavities, and you feel drafts at light switches and outlets.

What it costs in Hollywood

Drill-and-fill dense-pack cellulose for wood-frame walls in Hollywood runs $3,300-$6,900 per floor.

How we do it

We drill holes through the exterior sheathing, dense-pack the cavity with cellulose, and seal and patch each hole to match the siding.

What Wall Insulation Costs in Hollywood

Can you insulate the walls in a Hollywood CBS home without tearing out drywall?

Yes. Injection foam fills the empty block cores through small ports drilled in the mortar joints, so there’s no drywall removal. The ports are patched and matched after filling, and the work is isolated to the exterior wall surface.

Is wall insulation worth it in a Hollywood home when the attic is already insulated?

Sometimes. If the attic is sealed and insulated to R-38 and the A/C still runs constantly, the walls are the next leak. Here’s the call sequence: call (218) 261-7714 and we’ll measure the current envelope before recommending wall work.

Attic Cleaning & Rodent Proofing in Hollywood

Attic cleaning and rodent proofing in Hollywood is a real issue in the city’s older neighborhoods, where roof rats and squirrels find their way in through roofline gaps and eave openings. The problem compounds quickly because Hollywood’s salt-humid air means any urine or feces in the insulation holds moisture, and the smell is pulled into the living space every time the A/C cycles. We start with exclusion, then clean and sanitize, then make the attic airtight enough to hold heat out and keep rodents out. Rodent proofing plus a full attic cleanout in Hollywood runs $1,400-$4,800 depending on the extent of contamination. Our Attic Cleaning & Rodent Proofing work always ends with photo documentation of the finished condition.

Attic Cleanout

Signs you need it

You hear scratching in the attic at dusk, or you’ve found droppings, nesting material, or chewed wiring insulation in the attic space.

What it costs in Hollywood

An attic cleanout for a Hollywood home runs $1,300-$2,600 depending on attic size and debris volume.

How we do it

We remove all contaminated insulation and debris, HEPA-vacuum the attic floor, and photograph the clean surface before any new insulation goes in.

Rodent Proofing & Exclusion

Signs you need it

You’ve had an exterminator treat for rodents, but the problem returned within a season, which means the entry points are still open.

What it costs in Hollywood

Rodent proofing and exclusion for a Hollywood CBS home runs $900-$2,200 depending on the number of entry points sealed.

How we do it

We seal every roofline gap, eave opening, and pipe penetration with materials the specific rodent can’t chew through, then document each sealed point.

What Attic Cleaning & Rodent Proofing Costs in Hollywood

Do I need a pest control company or an insulation contractor for rodent proofing in Hollywood?

Both, in most cases. The pest control company handles the trap-out and population, but the entry points and the contaminated insulation are our scope. We coordinate with your exterminator so the exclusion work lines up with the treatment schedule.

How do I know if my Hollywood attic has rodent damage?

The strongest indicator is chewed fiberglass or wiring insulation, plus droppings or nesting material in the corners. If you hear animal sounds between dusk and dawn, call (218) 261-7714 and we’ll schedule an attic inspection.

Home Energy Audit in Hollywood

A home energy audit in Hollywood is the diagnostic that tells you exactly where your CBS home is leaking conditioned air and which fix will move the needle most. In a Climate Zone 1A city where the attic is the single biggest thermal liability, the audit usually points to the attic floor and ductwork as the top two priorities. We run a blower-door test, thermal imaging scan, and visual inspection of the attic, walls, and crawl space, then deliver a written report with measured numbers and a prioritized scope of work. Most audits in Hollywood run $350-$900, and if you choose us for the remediation work, the audit fee is credited. Home Energy Audit work in Hollywood is the starting point for any insulation job we quote.

Blower Door Test

Signs you need it

Your cooling bill is out of step with your home’s size, or rooms at the far end of the house never reach the thermostat setpoint.

What it costs in Hollywood

A blower-door test in Hollywood runs $350-$600 as a standalone service.

How we do it

We mount a calibrated fan in the front door frame, depressurize the house, and measure the CFM50 air leakage rate before and after air sealing.

Thermal Imaging Inspection

Signs you need it

You can feel temperature differences on interior walls and ceilings, or you suspect missing insulation but don’t want to open every wall.

What it costs in Hollywood

A thermal imaging inspection of a Hollywood home runs $300-$550 depending on home size.

How we do it

We scan every ceiling, wall, and floor cavity with an infrared camera, documenting temperature anomalies that indicate missing insulation or air leaks.

What Home Energy Audit Costs in Hollywood

Do I need a home energy audit before insulating my Hollywood home?

You don’t need one, but the audit removes the guesswork. It tells us whether the attic, the crawl space, or something else is the dominant leak, so we don’t spend your insulation budget on the wrong assembly.

What will the audit tell me that I don’t already know?

The blower-door CFM50 number, the location and volume of the worst air leaks, and which insulation investment will pay back fastest. You get the findings in writing before any work is quoted.
