"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"We are extremely pleased with Eli and the entire ELM team! We needed to remove and replace attic insulation after the Eaton fire and our location blocks from the canyon. Eli outlined the scope of work and answered all our questions. Alex and his crew did a very professional job of completing the difficult work efficiently and as planned. Miriam was a pleasure to work with in scheduling the work and coordinating payment. And the cost was a real value! Thank you very much for your expertise, quality work and excellent customer service.

"I wanted insulation blown in above the ceiling of my condo to lessen the noise from my neighbors above. Darren was very responsive and professional and knew exactly what I was looking for. The crew arrived on time, was very nice, and covered the house in plastic sheeting to protect everything from the incredible amount of dust created by drilling dozens of holes in the ceiling to shoot the insulation. Their subcontractor Robert arrived the next day to repair the holes and repaint the ceilings. He also was able to install can lights in my living room (separate job and quote from the job Attic Construction was doing). During installation of the lights, we discovered that some of the cavities that should have been filled by new insulation were not, due to a problem with the old insulation. One call to Darren and the insulation guys showed up early the next morning to take care of it. Robert the drywall guy and his helper Carlos did an amazing job repairing all the holes, you can't even tell that my ceiling looked like swiss cheese at one point. The reduction in sound coming from upstairs is noticeable due to the new insulation and I love my new lights. Be aware though that a job like this is incredibly messy and dusty but Attic Construction OC made it as easy as possible."

Insulation questions, answered by experts

Costs depend on insulation material, labor, accessibility, and whether existing insulation requires removal.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.
