Everything Las Vegas homeowners ask us about attic insulation: what R-value you actually need in the Mojave, which material suits your attic, what removal involves, what it costs, and how the install day works.
If your question is not answered here, call us and ask. Our attic insulation Las Vegas crews work across the whole valley, from free inspections through to same-day installation.
Attic Insulation Las Vegas is a local attic insulation company based at 3111 S Valley View Blvd, Suite B113, Las Vegas, NV 89102. We install, remove and upgrade attic insulation for homes and commercial buildings across the Las Vegas valley. We have worked in this market for more than 10 years and completed over 2,000 attic insulation jobs. Attic insulation is the only thing we do, which means our crews are not splitting their time between HVAC calls and duct work. They spend every day in Las Vegas attics and know what this heat does to insulation, which is the whole basis of how we approach the job.
Yes. Attic Insulation Las Vegas holds Nevada State Contractors Board license 0095881, under classification C-15C Insulation, the classification the state reserves specifically for insulation work. We also carry bonding and insurance on every job we take on. Ask any insulation contractor in Las Vegas for proof of all three, license, bond and insurance, before they start, and treat hesitation as an answer in itself. We provide documentation at the inspection.
That license gives you more than a piece of paper. The state operates a Residential Recovery Fund that pays homeowners back up to $40,000 when a licensed contractor fails to deliver, protection that simply isn’t available if you hire someone unlicensed. Nevada law also treats a contract with an unlicensed contractor as void, so if the work goes badly there’s no warranty to fall back on and nothing to take to court. On top of the license, we carry liability insurance and a surety bond, money held with the state as a guarantee that a homeowner can claim against if we don’t perform.
C-15C is the specific classification the Nevada State Contractors Board uses for insulation work. It’s narrower than a general contractor’s license, it means the state has verified this business specifically for insulation, not construction work in general. A contractor without this classification may be quoting attic work outside what they’re actually licensed to do, which is worth asking about directly.
More than 10 years, with over 2,000 completed attic projects across Clark County. That experience is specific to this climate, which matters more than it sounds. An attic in Las Vegas behaves nothing like an attic in Oregon or Michigan, and installation choices that are correct in a humid climate can be the wrong call in the Mojave. We also hold a 5.0 rating across 30 or more Google reviews, which you are welcome to read before you call.
Yes, both residential and commercial across the Las Vegas valley. On the residential side we work on single family homes, townhouses, condos and multi story residences. On the commercial side we insulate office buildings, retail spaces, warehouses and multi unit buildings. Commercial jobs usually need more planning around access, occupancy hours and scheduling, so we scope those separately.
We cover the full range of attic insulation work for Las Vegas homes and businesses: installation for attics that have never been properly insulated or for new construction, removal of old, damaged, contaminated or pest infested material, upgrades where insulation has settled or degraded below a useful R-value, emergency work after a leak or pest intrusion, and air sealing around the hatch, ceiling penetrations and other leak points.
It slows the movement of heat between your attic and the living space below. It does not block heat completely, no material does. Think of it as a speed limit on heat. Without it, a 150 degree Las Vegas attic dumps heat through your ceiling continuously all afternoon. With the correct depth in place, that heat takes far longer to reach the room below, so your air conditioner cycles on and off instead of running without a break.
Insulation laid across the attic floor slows the downward heat transfer from a sun-baked roof. Air sealing done at the same time closes the gaps around the attic hatch, recessed lights, ducts and ceiling penetrations where hot attic air physically leaks into your living space. Insulation without air sealing leaves a large part of the problem in place, which is why we address both together.
Yes. Overnight lows regularly drop into the 30s and 40s from December through February, and insulation works in both directions. In summer it keeps attic heat from coming down; in winter it keeps your heater’s warmth from escaping upward through the ceiling. Savings run year round, not just in July.
Signs include summer power bills in the $300 to $400 range or higher, upstairs rooms that stay hot late into the evening, an air conditioner that runs most of the day and never quite catches up, uneven temperatures room to room, heat radiating down from the ceiling, and a home built before 2010. A simple check: open the attic hatch and look across the floor. If you can see the tops of the ceiling joists, you almost certainly have less than R-30.
Fiberglass and cellulose both have a long material life, often 20 to 30 years or more, but performance degrades well before the material fails. Blown insulation settles and compresses over time, which is why so many Summerlin and Northwest Las Vegas homes built in the 1990s at R-19 now measure below R-11. The insulation is still there, it’s just no longer doing the job, which is why we measure actual depth rather than trusting the original spec.
Yes. ENERGY STAR and the U.S. Department of Energy put typical savings at 15 to 30 percent of heating and cooling costs for homes that bring an under insulated attic up to standard. Going from R-19 or less up to R-38 or higher, we commonly see summer bills drop by $80 to $150 a month.
Three materials, recommended based on your attic rather than what we’d prefer to sell: blown-in insulation (suits most Las Vegas attics), fiberglass batt insulation (for open attics with standard joist spacing), and cellulose insulation (for tight spaces, air sealing and recycled content).
Loose fill material delivered through a hose and blown across the attic floor. Because it flows rather than being cut to fit, it settles into every gap, corner and awkward space, including around pipes, wiring and ductwork. It’s what we use in most Las Vegas attics mainly for coverage, and it’s the most practical way to add depth on top of existing insulation without tearing anything out.
In open attics with standard joist spacing and few obstructions. Batts are pre-cut rolls, go in cleanly, and are the most affordable option. The tradeoff is precision, they only perform to their rated R-value with no gaps, compression or bunching. In an attic full of pipes, wiring or irregular framing, we’d steer you toward blown-in instead.
Made primarily from recycled paper treated with borate for fire resistance and pest deterrence. It packs more densely than fiberglass, sealing small air gaps more effectively with slightly more R-value per inch. The usual objection is moisture sensitivity, but in the Mojave that concern carries far less weight than in a humid climate, provided your roof and attic are dry and properly ventilated.
For most attics here, blown-in is the strongest all round choice, since coverage matters more in this climate than the differences between materials. Choose fiberglass batts if your attic is open and regularly framed on a tight budget. Choose cellulose for tight or hard to reach areas, best air sealing performance, or a preference for recycled material. In practice, installed depth matters more than which material you pick.
It measures how well a material resists heat flow, higher numbers mean slower heat transfer. It’s cumulative, so adding R-19 on top of an existing R-19 gets you to roughly R-38. It also depends on the material sitting at full, uncompressed depth, which is why an attic labelled R-19 in 1998 may measure far lower today.
The U.S. Department of Energy recommends R-38 to R-49 for Climate Zone 3B, which covers Las Vegas. We install to R-38 as a minimum and often to R-49. Most homes built before 2010 have R-19 or less, under half of what this climate calls for.
Commonly over 150 degrees Fahrenheit in July. If your living space is 75 degrees, that’s a 75 degree difference pushing heat down through your ceiling every hour of every summer afternoon, which is why insulation depths written for milder climates fall short here.
The materials are the same, the priorities aren’t. Cold climates focus on retaining furnace heat and managing condensation. Las Vegas is dominated by blocking extreme heat traveling downward for eight or nine months of the year, with moisture a much smaller factor in this dry climate. That means coverage and air sealing matter enormously here, and depth needs to exceed national minimums.
Roughly 15 inches of blown fiberglass (about R-2.5 per inch) or around 11 inches of cellulose (about R-3.5 per inch). Don’t calculate your own attic from those numbers though, settling, uneven coverage and existing material all change the math. We measure actual depth in several spots during the free inspection.
A technician comes to your home, accesses the attic, and spends roughly 30 minutes assessing it: measuring existing insulation depth in multiple spots, identifying the material and its condition, checking for air leaks around the hatch and penetrations, and looking for moisture, mold, pest activity or blocked ventilation. You get a clear recommendation on material, R-value and scope, plus an all-in price, with no charge and no obligation.
A two person crew typically takes 3 to 4 hours on a 2,000 square foot attic. In most cases we complete the installation the same day as the free inspection. If removal is required first, the job may extend into a second visit.
Usually no, the work happens in the attic and you can stay home. The exception is removal work, which generates dust. We contain it, but some homeowners who are sensitive to dust prefer to step out for a few hours. If anyone in the home has a respiratory condition, mention it when booking.
Very little. Clearing the area around the attic access helps the crew move equipment easily. If you store belongings inside the attic itself, let us know when you book so we arrive with the right materials to move or protect them.
We protect the work path and area around the attic access before starting, and full cleanup and disposal are included. It’s worth asking any insulation contractor whether disposal is included in the quoted price, since some quote installation and add a disposal charge afterward. Ours is written into the scope you approve up front.
We do a final walkthrough to confirm even, consistent depth at the agreed R-value, and check that ventilation paths haven’t been blocked. Most homeowners feel the difference the same day, particularly in upstairs rooms during the afternoon. The change in your power bill shows up on the next billing cycle.
In many cases yes. If what’s already up there is dry, clean, free of contamination and structurally intact, adding new material on top is sound and cost effective, since R-values add together. What makes it unsuitable is contamination, moisture damage, or compression so severe the old layer no longer performs.
When the existing material is contaminated by rodents or insects, carrying persistent odors, water damaged or showing mold, so compressed or deteriorated it no longer performs, or hiding damage that needs repair underneath. The free inspection establishes which situation you’re in.
Yes. Contaminated insulation needs full removal rather than covering over, both because it’s lost performance and because droppings and nesting material create an air quality problem your HVAC system will circulate through the house. One important point: insulation removal isn’t pest control, if rodents are still getting in, deal with entry points first or alongside the insulation work.
It closes physical gaps where air moves between your attic and living space, usual culprits being the attic hatch, recessed lights, plumbing and wiring penetrations, and ductwork joints. Insulation slows heat conduction but does nothing to stop air flowing through an open gap. We include air sealing where the inspection shows it’s needed, along with attic hatch and door insulation, as part of the quoted scope.
Not when installed correctly. The risk is insulation blocking airflow paths, particularly soffit vents around the eaves. We install baffles where needed and assess ventilation during the inspection rather than discovering problems afterward.
It depends on your attic’s square footage, the R-value you’re targeting, the material, accessibility, and whether old insulation needs removing first, removal moves the price the most. We don’t publish a single figure since a number without those details would be misleading. What we commit to is an all-in price given in writing before any work starts. Call (702) 745-7890 for a free inspection and a real number the same day.
All materials and the insulation product, labor and installation equipment, air sealing where required, attic hatch and door insulation, baffles and ventilation work, full jobsite cleanup, and disposal of any removed material. Nothing appears on the final bill that you didn’t agree to in advance.
ENERGY STAR and the DOE put typical savings at 15 to 30 percent of heating and cooling costs. Upgrading to R-38 or higher commonly works out to $80 to $150 a month off summer cooling bills, with bigger savings the further below standard you’re starting from.
Typically 18 to 36 months for homes upgrading from an under insulated attic, after which savings continue for the life of the insulation, measured in decades. There’s a second benefit too: a 150 degree attic wears on ductwork and forces your AC to work harder, so reducing that load can add years to a system that costs $5,000 to $12,000 to replace in this market.
Yes, we offer a discount for eligible customers covering military personnel, veterans and seniors. Mention it when you book or at the inspection so it’s applied to your written estimate up front.
The entire Las Vegas valley, including Summerlin, Spring Valley, Enterprise, Henderson, North Las Vegas, Downtown, Central, East, West and South Las Vegas, plus the Northwest and Centennial Hills. We’ve also extended direct service to Boulder City and Mesquite.
Usually within a day or two, often sooner, and in many cases we can inspect and install the same day. Summer is our busiest stretch, so if you’re planning an upgrade rather than dealing with an urgent problem, booking in spring or fall generally means more flexibility than calling during a July heat wave. For anyone comparing attic insulation in Las Vegas options, booking ahead of peak season is worth factoring in.
Yes, on most jobs. A standard installation or upgrade on a 2,000 square foot attic takes 3 to 4 hours, so a morning inspection can often mean same-afternoon work. Jobs needing full removal, unusually large attics, or difficult access may need separate scheduling, we’ll tell you at the inspection which category yours falls into.
Office hours are Sunday through Friday, 8:30am to 5pm, with an emergency line open 24/7. Emergency work covers situations that can’t wait, like a roof leak that’s soaked your insulation or a pest intrusion that’s contaminated the attic. Water damaged insulation left in place loses its R-value and can lead to mold, so it’s worth calling right away.
Call (702) 745-7890, or request a quote through the contact page. Tell us your address and roughly the size of your home and we’ll get you scheduled. The inspection is genuinely free with no obligation.
