Trusted Blown-In Insulation for West Hollywood Homeowners
Blown-In Insulation in West Hollywood typically runs $2.80-$5.40 per square foot installed, with most attic jobs finishing same-day and starting with a written price before any work begins. If your home was built between 1920 and 1980 - common in the Norma Triangle, Spaulding Square, or areas north of Santa Monica Boulevard - you’re likely dealing with original insulation that’s settled to half its R-value or less. We see this weekly.
Topside Attic Insulation West Hollywood has been independently owned and operated under The Haven Standard since 2016. We’ve sealed and insulated more than 9,000 homes, and we don’t blow insulation over an unsealed attic floor. Period. Our crews air-seal top plates, can lights, and every penetration first, then insulate. Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door numbers so you can verify the performance change you paid for. Calls to (213) 306-2607 are answered by a live person, 24/7.
What Our Blown-In Insulation Service Includes
Blown-In Cellulose
Blown-in cellulose is ground paper fiber treated with borate fire retardant, dense-packed to R-38 or higher in attics. West Hollywood’s 1940s-1960s bungalows and Spanish Revivals often have 3-4 inches of settled cellulose or rock wool that no longer meets code. We remove the degraded material when necessary, seal the envelope, then blow fresh cellulose to the depth specified in your written scope. Cellulose performs well in our climate because it handles the temperature swings between West Hollywood’s 85°F summer days and 45°F winter nights without the thermal drift you see with some fiberglass products.
Blown-In Fiberglass
Blown-in fiberglass - spun glass fibers blown through a hose to create a uniform thermal blanket - is what we recommend for homeowners who need maximum R-value per inch in constrained attic spaces. Many West Hollywood condos and townhomes, particularly the 1970s-1990s builds near Melrose and La Cienega, have shallow joist bays that limit insulation depth. We specify Owens Corning or Johns Manville fiberglass in these cases because it maintains R-value at the compressed depths those structures require. Like all our work, it goes in only after blower-door-guided air sealing is complete.
Dense-Pack Wall Insulation
Dense-pack wall insulation fills enclosed wall cavities with cellulose or fiberglass at 3.5 pounds per cubic foot, dense enough to resist settling but permeable enough to let walls breathe. This is the service we perform most often in West Hollywood’s pre-war duplexes and fourplexes - buildings with no insulation in the walls at all. We drill access holes, pack the cavities, then patch and texture-match to Los Angeles County standards. The blower-door test after dense-packing typically shows a 25-40% reduction in air leakage, and we give you that number in writing.
Blown-In Top-Up
A blown-in top-up adds material over existing insulation that hasn’t degraded but has settled below target depth. In West Hollywood, we do this most often for homes that had insulation installed 10-15 years ago and lost 20-30% of their original thickness. We don’t top-up over rodent-contaminated or water-damaged material - that’s a removal and replacement job, and we’ll tell you so in your free estimate. When conditions allow, a top-up is the most cost-effective way to restore performance without the labor of full removal.

Brands We Service for Blown-In Insulation
We source blown-in insulation materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in means we specify what’s right for your assembly, not what moves our inventory. We’ve installed thousands of bags of Owens Corning AttiCat fiberglass and GreenFiber cellulose in West Hollywood homes specifically, and we know how each performs in our local climate: Owens Corning for maximum R-value in tight spaces, GreenFiber for homeowners prioritizing recycled content and sound dampening in wall assemblies shared with neighbors, similar to our Blown-In Insulation in Culver City projects.
Whether your existing insulation is Demilec open-cell foam that needs supplementing with blown-in for cost control, or Johns Manville fiberglass from a previous contractor’s install, we can assess, match, or improve. We don’t claim exclusive status with any manufacturer. What we guarantee is that every material spec appears in your written scope, with the R-value and installed depth documented before anyone starts blowing.
Before
AfterSigns You Need Blown-In Insulation Right Now
- Your upstairs rooms run 8-12°F hotter in summer than downstairs. This is the signature of an under-insulated attic in West Hollywood’s climate, where unshaded roofs hit 140°F and radiate heat through inadequate R-value. We measure the difference with an infrared camera during our free estimate, then show you the thermal images.
- Your energy bill spikes every July and January. Pacific Gas & Electric and Southern California Edison customers in West Hollywood see predictable seasonal peaks, but a 30% jump over prior years usually means your insulation has settled or your envelope has opened up. The blower-door test pinpoints which.
- You can see floor joists in your attic. Insulation should bury joists in a uniform blanket. Exposed wood means settled or insufficient material, often R-11 or less where R-38 is code for our climate zone. We measure depth with a ruled probe and photograph it for your record.
- Your home was built before 1980 and never had insulation upgraded. Pre-Title 24 construction in West Hollywood typically has no wall insulation and attic insulation that’s compacted to 30-50% of original performance. We document this condition on every estimate, with photos you can compare to our finished work.
- You feel drafts near outlets, baseboards, or can lights on upper floors. These are thermal bypasses - air moving through unsealed penetrations because your insulation isn’t backed by an air barrier. Blowing insulation without sealing these first is like pouring water into a cracked cup. We seal every one before adding material.
Our Blown-In Insulation Process - Step by Step
- 1
Written price and scope before any work starts. Haven Standard Clause 1: flat price, written scope, written warranty delivered before anyone lifts a tool. Your estimate includes the blower-door target, the R-value we’ll achieve, the brands we’ll use, and the documentation you’ll receive. No surprises, no open-ended hourly rates.
- 2
Blower-door test and infrared scan. We pressurize your home to 50 Pascals - a standard pressure differential - and measure CFM50, the cubic feet of air moving through your envelope per minute. The infrared camera shows us exactly where that air is coming from: top plates, recessed cans, plumbing chases, duct boots. You get these images in your Documented Photo Record.
- 3
Air sealing of all penetrations and bypasses. We seal with fire-rated caulk, expanding foam, and rigid baffles as appropriate. Can lights get sealed housings or covers. Top plates get gasketed. This step typically takes 30-50% of total job time because we won’t blow insulation over leaks. The blower-door test after sealing confirms we hit our target reduction.
- 4
Insulation installation to specified depth and density. We set up containment, protect your living space, and blow cellulose or fiberglass to the depth in your written scope. Depth is checked every 100 square feet with a ruled probe. Density for dense-pack walls is verified by feel and resistance on the hose - our technicians know the difference between 3.2 and 3.8 pounds per cubic foot by experience.
- 5
Final blower-door test, cleanup, and documentation delivery. We test again, compare to our pre-work number, and add the result to your record. You receive: before-and-after blower-door readings, infrared images, installation photos showing depth and coverage, and your written warranty under the 365-Day Done Right Promise. The crew walks you through it before they leave.
How Much Does Blown-In Insulation Cost in West Hollywood?
A typical Blown-In Insulation pricing for an attic job in West Hollywood runs $2,800-$6,400 for homes between 1,200 and 2,500 square feet, depending on existing conditions and target R-value. Blown-in top-ups on attics with salvageable material start around $1,600. Dense-pack wall insulation for a 1,500-square-foot home typically falls between $4,200 and $7,800 because of the labor of access, packing, and patch-and-texture work.
What moves the price: current insulation condition (removal adds $1.20-$2.10 per square foot), attic accessibility (steep pitches or limited hatch access slow production), and whether we need to build storage platforms or baffle vents to maintain code-required airflow. We don’t quote by phone without seeing the space - but we do provide a written, flat price at your free estimate, with every line item explained.
How to avoid overpaying: get a second opinion. Under Haven Standard, we offer a Free Second Opinion on any written estimate. Bring us a competing quote and we’ll read it with you, line by line. We’ve found that West Hollywood homeowners who compare two detailed scopes - not just bottom-line numbers - end up with better performance and fewer callbacks. Your estimate from us includes the blower-door target, material specs by brand and R-value, and the documentation you’ll receive. If another quote doesn’t include those, it’s not comparable.

Frequently Asked Questions - Blown-In Insulation in West Hollywood
Blown-in insulation is loose-fill cellulose or fiberglass installed with a blower hose to create a continuous thermal blanket in attics or wall cavities. The material fills irregular spaces and covers joists or studs completely, eliminating the gaps left by batt insulation. In West Hollywood’s varied housing stock - from 1920s Spanish Revivals to 1980s condos - this adaptability makes Beverly Hills Blown-In Insulation the most reliable way to achieve consistent R-value across complex rooflines and additions.
Most attic jobs finish in one day; dense-pack wall work typically takes two days because of access, packing, and patch-and-texture requirements. We schedule a hard start time, not a window, and your written scope includes the expected duration. If we’re running behind because of unexpected conditions - we once found a colony of bees in a West Hollywood attic that required an exterminator - we tell you immediately and revise the timeline in writing.
Attic jobs typically run $2,800-$6,400, top-ups start around $1,600, and dense-pack walls fall between $4,200-$7,800 for a 1,500-square-foot home. The exact price depends on existing conditions, accessibility, and target R-value. We provide a flat, written price at your free estimate - no work starts without it. Call (213) 306-2607 to schedule; estimates are free and include blower-door and infrared documentation.
Yes. We’ve installed thousands of bags of Owens Corning AttiCat fiberglass and Johns Manville blown-in products in West Hollywood homes, and we stock both for same-day availability. We don’t claim exclusive or preferred status with either brand - we specify what’s right for your assembly. Your written scope names the brand, the product line, and the installed R-value before work begins.
We answer calls 24/7 and can typically dispatch for same-day estimates in West Hollywood and surrounding areas. True insulation emergencies are rare - this isn’t a burst pipe - but we treat urgent comfort issues (no heat in January, a newborn arriving home to an uninsulated nursery) with priority scheduling. A live person answers at (213) 306-2607; no voicemail loops, no callback windows measured in business days.
Every job is covered by our 365-Day Done Right Promise - if it’s not done right, we make it right. The promise is backed by a written scope and written warranty delivered before anyone starts, per Haven Standard Clause 1. For blown-in insulation specifically, we also guarantee the installed R-value and depth documented in your record; if settling exceeds manufacturer specifications in year one, we top it at no charge.
Clear attic storage to the center of the floor or remove it entirely; our crew needs access to perimeter plates and penetrations. Cover any items that remain with the plastic sheeting we provide. For dense-pack wall work, move furniture 3 feet from exterior walls and remove wall hangings. We’ll walk through the specific prep for your job at the estimate - it’s part of the written scope, not a surprise instruction the morning of.
