I can see how better insulation can save energy bills, especially in the winter. I honestly don't know how much insulation I have, I should probably look into that. It's an extra nice perk that adding insulation also adds to the homes value. Thanks for the info! http://www.mincin-insulation.com/services

I had a house once that I had cellulose blown in by "Professionals" at the time I didnt think to check the work, at a later date I did make my own check of the work due to personal reasons. I found that there were voids where the insulation had not been properly filled in the cavities. My estimation is about 25% not related to settling which they say is typically 10%...
After moving to Spokane and experiencing my first winter, I insulated with cellulose during the spring and did the work myself. The big box store blower are useless for this application, they work great in theory for attics but that is it.
I used several of the big box store machines all of them were deficient and were in obvious need of repair ie. Broken blower air hose under the machine, faulty hoses that clogged up during the work, but worst of all regular maintenance and verifying that the said machines were going to be problem free and in good condition prior to renting or turning them over to the customer.
Since I was blowing the insulation into my walls I ended up using with good success a leaf blower to install my insulation. The results were a bit better however there were still voids that I am currently doing by hand from the inside at this time.
Once in the wall Im compressing it with a homemade tool to pack it in the cavity.
The results finally are to my satisfaction the interior air temp is 70 degrees, the wall temperature on the interior surface is 68 degrees. Time consuming but I know at least it has been correctly...

The issue of settling is discussed in this article here on the blog http://cellulose.org/GreenestInsulation/2016/02/19/settling-the-myth-about-cellulose-insulation-settling/. Glad to hear you were satisfied with your DIY install. However, CIMA recommends using a contractor experienced with installing cellulose insulation for all applications and particularly in walls and retrofits. We offer information about hiring a contractor on the website http://cellulose.org/HomeOwners/QuestionsAskContractors.php. Also, a search feature to find cellulose insulation producer for every state who may also be able to provide recommendations for qualified insulation contractors http://cellulose.org/CIMA/insulation_contractors.php
