Insulation Installation

How much does it cost to have insulation installed?

In order to install cellulose insulation, a homeowner would need to rent a blower from Lowe’s, Home Depot, or most other large hardware stores. To start filling in the insulation, blow the cellulose up to the floor joists. For best results, distribute the insulation in an even layer.

If this sounds like a lot of work, it’s because it kind of is. Have a pro install it for you. Complete the form to the right for your free inspection and estimate.

How long does it take to insulate a house?

If done correctly. Insulating a house should take no more more than a day or two.  It pushes on day two when the home requires additional ventilation air seal or mold treatment is needed.

How do you tell if your house is well insulated?

Understanding insulation involves understanding heat flow.  A basic rule is that heat energy transfers from hotter places to colder places.  Conduction is a word you’ll hear in this industry and conduction occurs when heat moves through solid matter. 

Insulation works by slowing conductive heat transfer. It does this by trapping air in the insulation material and keeping the air from moving. You will know your insulation is working if it cost and takes little energy to keep your home comfortable. 

What's the best insulation for walls?

There are many types of insulation with specific uses

Batt Insulation:  This is the insulation you see normally delivered in rolls. Faced batts come with vapor retarder and unfaced batts does not contain vapor retarder.  this insulation is common because it is easily available at a comparatively low cost. it is mostly made from fiberglass with their R value ranging between 3 and 4 per inch.

*Fiberglass can irritate skin and lungs, but is not an issue for homeowners unless they are in direct exposer to the insulation.

Uses: Installed Between Framing Members

Spray Foam Insulation: Available in bulk form for large jobs or in cans/kits for homeowners. Spray foam ma need protection from ignition as they are flammable. This insulation is used as a spray or injected into walls. The r value on open cell spray foam is about 3.7 per inch closed cell is 6 per inch. 

Uses: It can also be used on roof sheathing, rafters, in crawl spaces, and framing

Sheet Insulation:  As the name suggests, this insulation is found in 4-foot wide sheets of various length. Many of these sheet insulation need to be protected from ignition because they are flammable and produce toxic smoke when burned.  They can start with an R – value of 8 per inch but lose some over time making the average R value around 6. 

Uses: Exterior sheathing or visible in attics and crawl spaces. 

Loose Fill/Blown-in: This insulation comes in bags and poured into the hopper of a machine to be blown by air into the space being insulated. This type of insulation I usually made with either fiberglass or cellulose.  Its R value ranges between 2.2 – 2.7 per inch. 

Uses: Installed on attic floor

"Recently did my home. Tim and the Addison crew came out and did my attic properly as it should’ve been done the first time. Explained every single question (i had a lot) i had before and during the job. Tim made sure during the job they were doing the air sealing properly because that’s what makes the biggest difference in keeping the cool/heat in the house and so that it doesn’t get lost in translation somewhere in in the attic. Highly recommend and speak with Tim when doing work in your property!"

James is prompt, thorough, and personable -- responded to my website inquiry right away and made it easy to schedule an appointment (still haven't heard back from the competition -- that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I'm glad I contacted Green Attic.

Tim and his crew then came out to remove the old insulation, clear/kill all the mold in the attic, remedy issues that were causing the mold in the first place (insufficient ventilation and blocked soffits), and finally re-insulate our attic/basement. The work was intense, but Tim's transparency with the process and willingness to educate us on the problems that we were having were what sold us. We also appreciated that Tim was able to work in some added value into his services without charging us the difference.
