Attic Insulation in Henderson, NV
Sunrise Service installs blown-in attic insulation for existing homes across Henderson and the Las Vegas valley. It is the least glamorous improvement you can make to a house and usually the one with the shortest payback — because in this climate, an under-insulated attic is where most of your cooling goes.
UNDERSTANDING R-VALUE
How much insulation should a Las Vegas attic have?
The Department of Energy recommends R-30 to R-60 for attics in this climate zone. A great many Henderson homes have considerably less than that, and most homeowners have no idea which group they are in.
R-value measures resistance to heat flow — the higher the number, the slower heat moves through it. Southern Nevada sits in climate zone 3, where the problem is almost entirely heat coming in rather than heat escaping. An attic that reaches 150 degrees on a July afternoon sits directly above your ceiling, and the only thing between the two is insulation.
If your house was built before about 2000, it was very likely insulated to the standard of its day rather than the current one. That does not make it defective. It makes it a candidate.
WARNING SIGNS
How do I know if my attic needs more insulation?
Four signs, none of which require going into the attic.
- Rooms on the top floor run hotter than the rest of the house, particularly in the afternoon.
- Your cooling bill is higher than neighbors with similar-sized homes.
- The air conditioner runs almost continuously in July and still does not quite get there.
- The house cools down quickly in the evening and heats up quickly in the morning — a sign the building is not holding temperature.
The definitive check is simpler: look at the attic floor. If you can see the tops of the joists, you have around six inches or less, which is well below current recommendations. If the insulation is level with or above the joists, you are in better shape.
What happens during an attic insulation installation?
Assessment
We measure what is in the attic now, check for gaps and compression, and look for the things that have to be dealt with first — air leaks around fixtures, exposed ductwork, any sign of moisture.
Preparation
Soffit vents are baffled so the new material does not block airflow, and recessed lights and flues are kept clear to the manufacturer’s required distance. Skipping this is how an insulation job causes a problem instead of solving one.
Installation
The material is blown to the specified depth across the attic floor, including the perimeter, which is the area most often left short.
Verification
Depth is checked against the target in multiple places and the work area is cleaned. Blown-in installation is messy while it is happening and should not be messy afterward.
EFFICIENT ATTIC COVERAGE
What is blown-in insulation, and why use it in an existing home?
Blown-in insulation is loose material — typically fiberglass or cellulose — installed with a hose rather than laid in rolls. In an existing attic that matters, because the obstacles are already there.
A finished attic is full of things batts cannot fit around: joists at irregular spacing, wiring runs, ductwork, recessed light housings, bracing. Rolled insulation has to be cut to fit and leaves gaps at every cut. Blown-in material fills the space it lands in, including the awkward parts, which is where heat finds its way through.
It also installs over what is already there. If your attic has six inches of old fiberglass that is intact and dry, it usually stays — we add to the depth rather than removing and starting over.
Customer Reviews
What Our Customers Say
I was immediately helped on Easter Sunday when I had no hot water. They had a technician come within a few hours. The Tech, Tristin is so professional and clearly explained my choices. He ended up replacing my hot water heater and fixing the holdings.
Margy F.
I recently had a water heater replaced. Omar came out and was extremely professional and thorough. He took the time to discuss routine maintenance that would help prolong the life of my new water heater.
Adrian R.
I recently got a tankless water heater installed and I love being able to take endless hot showers… Thank you Jason for helping me understand the benefits and making sure everything went well with the installation.

Will adding attic insulation lower my cooling bill in Henderson?
Usually, and the hotter your summer runs the more it does. Insulation does not produce savings on its own — it reduces the work your air conditioner has to do, and in a climate where that system runs most of the year, the reduction compounds.
The second effect matters as much and gets discussed less: comfort. A properly insulated attic reduces the temperature swing between rooms, so the back bedroom stops being four degrees warmer than the living room every afternoon. Homeowners frequently notice that before they notice the bill.
It also takes load off equipment. An air conditioner that runs fewer hours wears more slowly, which matters on a system you would rather not replace early.
Is attic insulation worth it in an older Henderson home?
Often it is the single best-value improvement available, precisely because older homes have the most room to improve.
A house built to a 1980s standard has roughly half the insulation currently recommended for this climate. The gap between where it is and where it should be is the return. A newer home built closer to current code has less to gain, and we will say so rather than sell you something marginal.
It also pairs naturally with equipment work. If you are replacing an air conditioner, doing the attic first means the new system is sized for a house that holds its temperature rather than one that leaks it — which occasionally means a smaller, cheaper unit.
Frequently Asked Questions
How much insulation should a Las Vegas attic have?
The Department of Energy recommends R-30 to R-60 for attics in this climate zone. Many Henderson homes built before 2000 have significantly less. The quickest check is to look at the attic floor — if you can see the tops of the joists, you are likely below current recommendations.
Can you add insulation over existing insulation?
Usually yes. If the existing material is intact, dry and not compressed, blown-in insulation goes over the top and adds to the total depth. Existing insulation only needs removing if it is wet, damaged or contaminated, and we will tell you which situation you are in before any work starts.
What type of insulation do you install?
Blown-in attic insulation for existing homes. That is the whole of what we install — we do not do spray foam, radiant barrier, wall insulation or new construction, and if one of those is what your home actually needs, we will say so.
How long does attic insulation take to install?
Most residential attics are a single-day job. Preparation — baffling soffit vents and keeping clearances around lights and flues — takes a meaningful share of that time and is not a step worth rushing.
Will more attic insulation help in winter too?
Yes, though in Southern Nevada the summer benefit is the larger one. Insulation slows heat movement in both directions, so the same installation that keeps heat out in July keeps it in during December.
Do I need to be home during the installation?
Someone should be there at the start so we can walk the attic with you and confirm what we found, and at the end to see the finished depth. The installation itself does not require you to stay.
