The Attic Insulation Inspection Process
What to Expect from your Attic Inspection with Jacob, Company Owner & Your Personal Home Comfort Expert
YOUR ATTIC INSULATION INSPECTION IN 3 STEPS
Step 1: Comprehensive Attic Inspection
After introducing myself and asking a few quick questions to figure out what problems you’re trying to solve, I’ll head up into the attic to try to pinpoint the source of the issues. On average you can expect me to be up there for about 10 minutes while I’m taking photos and recording measurements to give you the most complete picture of what I find. During my inspection I’m looking at five things in particular:
- Insulation Type: What type of insulation do you currently have in your attic – fiberglass, cellulose, mineral wool, and balsam wood are all commonly found in the Boise area, depending on the home’s age.
- Insulation Depth & Consistency – How deep is your attic insulation? Is it high in some places and low in others? Is there anywhere that it’s missing entirely?
- Insulation Quality: Has your insulation been compressed from previous foot traffic? Are there any signs of water damage or pest infiltration?
- Attic Ventilation: Does your attic have enough ventilation to release heat in the summer and humidity in the winter? Are your soffit vents properly baffled and unobstructed?
- Top-Priority Issues: Disconnected bathroom exhaust vents, roof leaks, loose ductwork – anything that you’d want to take care of before having more insulation installed.
Step 2: Inspection Findings & Photo Review
Once I’m down from the attic I’ll review the photos I took to show you exactly what I found, covering all five points I focus on during my inspection and taking all the time we need to answer any questions you may have as they come up.
Step 3: Personalized Recommended Solutions
Now that we both know about all of the problems in your attic (if any), I’ll lay out the best options to solve them. All recommendations are based on a thorough understanding of the building science behind home insulation and a commitment not to offer anything that I wouldn’t install in my home myself. This part is much less “selling” than you might expect: no high-pressure closing tactics or “limited time offers”, just an honest appraisal of what would benefit your home based on your specific situation.
Curious about the Attic Insulation Install Process?
Here’s What to Expect on Install Day
After your Home Comfort Expert introduces you to our Expert Installers and does a quick review of the project paperwork to confirm the exact work we’re doing, we’ll get straight to setting up for the install. When we’re insulating a garage or any other relatively small attic space, this is usually the longest part of the process because of everything we do to make sure that the install goes perfectly and cleanup is a breeze. In the words of Benjamin Franklin, “An ounce of prevention is worth a pound of cure”.
This is where the real fun starts for us, but you can typically carry on with your day as if we weren’t even there. Whether adding blown-in insulation onto your attic floor or securing batt insulation to bonus-room walls, the only sign of us will typically be the sound of our footsteps above your head and the sight of our blower hose running up into your attic access. We value your time and aim to be as efficient as possible, but doing the job right while keeping you informed is always our top priority – don’t be surprised if we interrupt you once or twice to keep you updated on our progress.
Cleanup & Review
Our goal is always to leave your home as clean as we found it. The prep work we do during our setup makes this part pretty quick, but you can still expect us to make a few passes through where we’ve been working to make sure we’ve left it spotless. Once the inside of your home is clean, our Lead Installer will review before & after photos of the work we completed, answer any remaining questions you have, and collect payment for the project while the rest of the team is outside packing up our equipment and taking care of the final cleanup. Before you know it we’ll be out of your hair and you can expect an email with your receipt and a link to those photos by the end of the day!

You Have Questions?
We Have Answers.
What does “R-Value” mean?
The R-value of a material is a measure of its thermal resistance – you can think of it as the “insulating power” of the material. The higher the R-value, the greater the insulating power!
How much attic insulation do I need? What R-value should my attic be?
We recommend a minimum attic insulation R-value of R-49. This is based off of the International Residential Construction Code (IRCC) recommendation for our climate zone here in the Boise area. We’ve found that an R-49 is the best balance of upfront cost and long-term efficiency and comfort for most homeowners we work with (and the building science data backs this up). If you’re planning on living in your home for more than 7-10 years it’s worth considering bringing your attic insulation up to R-60, which is going to yield the best long-term savings in energy efficiency and is guaranteed to keep you comfortable year-round.
The minimum R-value required by most local building codes in the Boise area is R-38. This lower requirement is due to builders having a heavy influence over which new building codes get adopted each year, and if you know how most builders operate then you know they’re always looking to cut costs wherever possible. While you can usually get by with R-38 attic insulation, it’s inevitable that your AC & furnace will struggle to keep your home comfortable and your energy bills will be higher than necessary year-round.
What is more important, insulation depth or R-value?
R-Value! Insulation depth means nothing without knowing the R-value of the material.
For example, when installed to manufacturer’s specifications blown-in fiberglass insulation produced by CertainTeed requires a minimum installed depth of 18.25 inches to achieve an R-49 while Owens Corning’s blown-in fiberglass only requires a minimum depth of 16.75 inches.
What is the best type of attic insulation? Should I use fiberglass or cellulose?
Blown-in fiberglass insulation is a much better choice than cellulose for attic insulation in terms of both upfront cost and long-term performance.
This is a long-standing debate in the insulation industry that takes a lot more than a couple of lines to fully explain (you can watch a 20 minute video we made on the topic here), but the short answer is that improvements in the material science of fiberglass insulation production and the deterioration of the source material quality for cellulose insulation (recycled newsprint) means that modern fiberglass insulation is a much better choice than cellulose in the vast majority of cases.
What type of attic insulation do you install?
We install blown-in and batt fiberglass insulation.
On custom new construction projects we work with another company that installs spray foam insulation. If you’re looking for spray foam alone, we’d recommend contacting a spray foam contractor directly.
Is batt insulation or blown-in insulation better for my attic?
Blown-in insulation is almost always a much better choice than batts when insulating an attic for two main reasons:
- More Even Coverage – batt insulation leaves gaps around attic framing, pipes, and wires, leading to thermal bridging and resulting in a lower effective R-value than the even, consistent coverage achieved by blown-in insulation
- Lower Labor Cost To Install – properly installing batt insulation requires a lot of time spent cutting material around framing, wiring, pipes, and vents while blowing in insulation is a much more routine process
How long does it take you to insulate an attic?
In most cases we can complete an attic insulation project in 4-6 hours. The time it takes to insulate an attic ultimately depends on the size and complexity of the space, but you can typically expect us to be working in your home for about half a day.
