"Koala replied to me quickly. I had 3 quotes, Koala provided the insulation I needed at a good price, but beyond that, the customer service from the quote to the work was great. It was seemless and all done with kindness, willing to take time to explain and answer questions. Prompt, in fact I made my decision on a Friday with a Monday completion. THANK YOU"

"I hired Gary from EcoSystems in order to increase my attic insulation from R38 to R49 and I wasn't disappointed. He used all the SRP rebates available in order to reduce the price for me. I contacted a few more companies and Gary was the cheapest by $300-$600 so I hired him. He came promptly at the time set and after a few questions he started the work. After an hour or so the attic was recovered of cellulose. I took a quick look and it looked fantastic. The crew cleaned up after themselves and the entire experience was painless. I would recommend Gary if you are in the Phoenix area. Also he told me that if I had talked to my neighbors and someone else would have had their insulation done the same day, price would have been lower so I'm passing this information along."

Insulation questions, answered by experts

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

Winterizing your outdoor plumbing keeps your outdoor spigot from freezing and potentially bursting. This includes draining residual water out of the pipe and spigot after turning the valve off, then removing garden hoses and other attachments from the spigot before winter comes. Insulating the pipe that leads to the spigot and installing a freeze-proof faucet also help, as does installing an outdoor faucet protector.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.
