Trusted Attic Insulation for Long Beach Homeowners
Most attic insulation jobs in Long Beach run between $1,800 and $4,500 depending on square footage, existing insulation condition, and whether air sealing is needed first. We can usually assess your attic and provide a written price the same day you call. If your upstairs rooms run hot in August or your Pacific Gas & Electric bill spikes every summer, the attic is almost always the culprit.
We’ve sealed and insulated more than 9,000 homes since 2016, and every one started with a written price before any work began. In Long Beach, we regularly see attics with original 1960s Attic Batt Insulation compressed below R-19, or newer homes in Alamitos Heights where builders skipped air sealing entirely and blew fiberglass over leaky top plates. The result is the same: conditioned air escapes into the attic, the HVAC runs overtime, and the homeowner pays for comfort they never feel. Wes Okafor built this company under The Haven Standard so customers would never have to negotiate for basic documentation - a written scope, a written warranty, and before-and-after blower-door numbers when air sealing is part of the job.

What Our Attic Insulation Service Includes
Blown-In Attic Insulation
Blown-in insulation - loose-fill cellulose or fiberglass applied with a hose and blower - fills irregular joist cavities and covers the attic floor with a continuous thermal blanket. In Long Beach, we use it most often in homes built between 1940 and 1980 where original batts have settled or been disturbed by prior work. We never blow insulation over an unsealed attic floor; our crews seal top plates, wire penetrations, and can-light housings first, then blow to the depth that achieves your target R-value, typically R-38 to R-49 for this climate zone.
Attic Batt Insulation
Batt insulation - pre-cut fiberglass or mineral wool panels sized to fit standard joist spacing - works best in attics with regular framing, clear access, and minimal obstructions. We install it in newer Long Beach construction, particularly in Naples and Belmont Shore where builders left attics clean but under-insulated. Our crews cut around electrical boxes and vent stacks without compression gaps, because compressed batt loses up to 50 percent of its rated R-value. Every batt job includes a documented photo record showing full contact with the attic floor and no voids at the eaves.
Attic Insulation Top-Up
An Attic Insulation Top-Up adds material over existing insulation that is in good structural condition but below current code depth. This is the most common call we get in Bixby Knolls and California Heights, where 1980s and 1990s homes were built to R-30 and now need R-38 or R-49. We test the existing layer for moisture damage, rodent activity, and proper placement first. If it’s clean, we air-seal the attic floor and blow new material to achieve uniform depth across the entire footprint. Most top-ups in Long Beach run $1,800-$2,800 for a 1,200-square-foot attic and take one day.
Attic Insulation Replacement
Attic Insulation Replacement means removing existing material that is contaminated, water-damaged, or improperly installed, then starting fresh. In Long Beach, we do full replacements most often after roof leaks near the port, rodent infestations in older Wrigley District homes, or DIY jobs where vapor barriers were installed upside-down and trapped moisture. Our crews bag and remove the old material, HEPA-vacuum the attic deck, treat for odor and biological growth if needed, then install new insulation to a written scope with photo documentation at each stage. Replacement typically costs $3,200-$5,500 and requires two days.
Attic Baffles & Ventilation Prep
Attic Baffles & Ventilation Prep - also called vent chutes or rafter vents - are channels that keep soffit intake air flowing over the insulation rather than through it, preventing wind-washing that degrades R-value and moisture buildup that breeds mold. We install them in every Long Beach attic where the insulation depth will cover the soffit vents, which is most jobs. Proper ventilation prep also includes calculating the ratio of intake to exhaust ventilation for your roof geometry. In homes near the water, where marine layer moisture lingers, this step prevents the condensation problems we see repeatedly in Bluff Park and Belmont Heights.

Brands We Service for Attic Insulation
We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, no house brand pushed for margin. Owens Corning ProCat and Johns Manville Climate Pro are our most-specified blown fiberglass products in Long Beach; we’ve installed both in hundreds of attics and can show you the blower-door delta on comparable jobs. For homeowners prioritizing recycled content, GreenFiber cellulose - all-borate fire retardant, 85 percent recycled paper - performs well in our climate and typically runs 10-15 percent less per square foot than synthetic options.
Demilec and Icynene are the spray foam systems we use for hybrid attic jobs, where open-cell foam seals the attic floor and blown material builds R-value above it. We’ve sprayed both brands in Long Beach crawl spaces and rim joists, and our crews are trained to the manufacturers’ density and lift-thickness specifications. Whether your existing insulation is Owens Corning, GreenFiber, or any other make, we can assess it, match or exceed its performance, and document the improvement.
Signs You Need Attic Insulation Right Now
- Your upstairs rooms are 8-12 degrees hotter than downstairs in summer. This is the classic Long Beach complaint from June through October. Heat radiates from an under-insulated attic deck into the conditioned space below, and the HVAC ductwork - often routed through that same hot attic - loses cooling before it reaches the register. The fix is rarely a bigger air conditioner; it’s stopping the heat gain at its source.
- Your energy bill jumps 30 percent or more in summer months. We see this pattern every year in homes east of the 405, where inland heat meets coastal humidity. If your usage hasn’t changed but your bill has, the building envelope is leaking. A blower-door test - a pressurization reading that shows, in one number, how much air your home is losing - will isolate attic leakage from window or duct leakage.
- You can see floor joists through the existing insulation. Insulation settles over decades, and original batts in Long Beach’s postwar housing stock were often installed at R-19 or less. If the pink or yellow material sits below the top of the joist, you’re getting a fraction of the thermal resistance you need for Climate Zone 3. We measure depth with a ruled probe and photograph it for your record.
- You’ve had ice dams, roof leaks, or visible mold in the attic. Even in mild Long Beach winters, temperature differentials between attic air and conditioned air can create condensation on cold surfaces. Wet insulation loses R-value, compacts, and supports mold growth. We remove compromised material, fix the moisture source - usually ventilation imbalance or air leakage from below - and reinstall to a dry, sealed cavity.
- Your home was built before 1990 and never had an insulation upgrade. California’s Title 24 energy code has been tightened four times since 1990, and pre-code homes in Wrigley, North Long Beach, and the Washington neighborhood routinely test at R-11 to R-19 in the attic. These homes cost more to cool than comparable square footage built to 2008 standards or later. The gap is fixable in one day for most single-story homes.
Our Attic Insulation Process - Step by Step
- 1
Schedule and arrival. When you call (424) 415-7031, a live person schedules your appointment and sends a text with your technician’s name and photo when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician. We serve Long Beach and surrounding cities with typical response times of same-day to 48 hours depending on season.
- 2
Attic inspection and blower-door test. We open the attic hatch, photograph existing conditions, and run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. In Long Beach’s older housing stock, we typically see starting readings of 3,500-5,500 CFM50. We mark air-leakage points with smoke pencils and note insulation depth, moisture staining, and ventilation adequacy.
- 3
Written price and scope. Before any work starts, you receive a flat price, a written scope of work, and a written warranty. This is Haven Standard Clause 1, non-negotiable since 2016. The scope specifies material type, target R-value, air-sealing details, ventilation corrections, and cleanup responsibilities. No surprises, no day-of changes without a signed amendment.
- 4
Air sealing first, then insulation. We seal top plates, electrical penetrations, can-light housings, chimney chases, and duct boots with fire-rated caulk, foam, or rigid blocking as appropriate. Only after the attic floor is sealed do we install insulation. This sequence is the core of our work; blowing insulation over leaks is like putting a sweater on over a screen door.
- 5
Final test, documentation, and walkthrough. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers on your invoice. You receive a Documented Photo Record showing attic conditions, material depth, sealed penetrations, and ventilation baffles in place. The 365-Day Done Right Promise applies from this moment: if it’s not done right, we make it right.
How Much Does Attic Insulation Cost in Long Beach?
A typical attic insulation top-up in Long Beach runs $1,800-$2,800 for a 1,000-1,500 square foot single-story home. Full replacement with removal of existing material runs $3,200-$5,500. New insulation in an unfinished attic space, including air sealing and baffles, typically falls between $2,800 and $4,500. These ranges assume standard truss or joist framing, safe attic access, and no active roof leaks or rodent infestations requiring remediation.
Several factors move the price within these ranges. Attic square footage is the largest driver; Long Beach’s 1920s bungalows in Belmont Heights may have 600 square feet of attic, while 1950s ranch homes in Lakewood Village run 1,200-1,400 square feet. Existing insulation condition matters: removal and disposal of contaminated material adds $0.75-$1.25 per square foot. Air sealing complexity varies with ceiling penetrations; a kitchen with six can lights and a vent hood penetration takes longer than a bedroom with one ceiling fixture. Access difficulty - steep roof pitch, narrow scuttle, or detached garage attic - affects labor hours.

Frequently Asked Questions - Attic Insulation in Long Beach
Attic insulation is a thermal barrier that slows heat transfer between your conditioned living space and the unconditioned attic above. In Long Beach, where summer attic temperatures regularly reach 140°F, proper insulation keeps that heat from radiating downward and forcing your air conditioner to run continuously. Without it, you’re paying to cool air that escapes through the ceiling as fast as your HVAC produces it.
Most attic insulation jobs in Long Beach are completed in one day. A standard top-up or air-sealing-and-blow job on a 1,200-square-foot attic takes 4-6 hours of crew time. Full replacements requiring material removal, deck cleaning, and remediation may extend to two days. We schedule arrival for 8:00 a.m. and aim to have the crew off-site by mid-afternoon for single-day jobs. Call (424) 415-7031 for availability - estimates are free.
Attic insulation in Long Beach typically costs $1,800-$5,500 depending on whether you’re adding to existing material, replacing contaminated insulation, or starting fresh in an unfinished space. A top-up to R-38 for a standard single-story home usually falls in the $2,200-$2,800 range. We provide a written price before any work starts, and our Free Second Opinion service lets you verify any competing quote against our scope. Call (424) 415-7031 for an exact quote - estimates are free.
Yes. We install Owens Corning fiberglass batts and blown systems regularly, and we apply Icynene open-cell spray foam for hybrid attic jobs where air sealing at the floor plane is critical. Our crews follow manufacturer specifications for coverage rate, lift thickness, and cure time. We do not claim exclusive or preferred status with any brand; we specify what performs for your attic’s condition and your priorities.
We answer calls 24 hours a day, and we prioritize attics with active roof leaks, post-fire restoration needs, or health hazards such as severe mold. For non-emergency efficiency upgrades, we schedule within 24-48 hours. If your situation is urgent, call (424) 415-7031 and a live person will assess whether same-day dispatch is warranted.
All completed attic insulation is backed by our 365-Day Done Right Promise - if it’s not done right, we make it right. This covers material settling below specified depth, air-sealing failures detectable by blower-door retest, and workmanship defects. The warranty terms are written and delivered before any work starts, per Haven Standard Clause 1. We also pass through any manufacturer warranty on materials, typically 10 years for fiberglass and lifetime for certain foam products.
Clear a path from your front door to the attic hatch and remove any stored items from the attic floor. We need 6 feet of clear workspace below the hatch for our ladder and hose equipment. If you have pets, secure them in a closed room away from the work area; our blowers are loud and our crews open and close exterior doors frequently. We’ll handle protective floor covering, furniture draping, and cleanup - it’s included in every job, not available on request.
