Crawl Space Encapsulation Services in The East Valley
Enhance Home Comfort and Air Quality with Crawl Space Encapsulation
Crawl space encapsulation is essential for homeowners looking to improve energy efficiency, indoor air quality, and moisture control. Many crawl spaces are vulnerable to moisture, mold, and pests, which can lead to structural damage and higher energy bills. By sealing and insulating your crawl space, you create a protective barrier that keeps moisture and drafts out, while improving the overall energy performance of your home.
At Koala Insulation, we use durable vapor barriers and insulation materials to fully encapsulate crawl spaces, ensuring they stay dry, clean, and energy-efficient. Encapsulation also prevents outside air from infiltrating your home, creating a more stable indoor environment.
Benefits of Crawl Space Encapsulation
- Moisture Control: Sealing your crawl space prevents moisture from entering, reducing the risk of mold, mildew, and wood rot. This extends the life of your home’s foundation.
- Energy Savings: By insulating and sealing your crawl space, you prevent conditioned air from escaping and unconditioned air from entering. This improves the energy efficiency of your home and reduces heating and cooling costs.
- Improved Air Quality: Encapsulation reduces the entry of outdoor pollutants and allergens into your home. This can greatly improve indoor air quality, making your home healthier, especially for those with allergies or respiratory issues.
- Enhanced Comfort: Crawl space encapsulation helps maintain a more consistent temperature throughout your home by eliminating drafts and cold floors.
- Pest Prevention: Encapsulation helps deter pests, such as insects and rodents, from entering your crawl space and potentially damaging your home.

They came out originally and gave me an estimate and they were willing to work with the SRP⚡️ rebates, which was great. They had a very reasonable price among their competitors, and we’re not pushing at all. They came out and did the work about two weeks later, and we’re fast efficient. Very on top of the communication. Would definitely recommend this business to any friends and family.

HIGHLY RECOMMENDED! Service: Insulation & duct repair.
I reached out to 3 insulation companies before making a decision. Out of the 3, Jim and his son Ryan took the most time inspecting, photographing and documenting the issues found in the attic space. I was impressed, not only for the professionalism but the way the explain the findings and the available solutions to address my concerns. Initially, I was thinking about removing the existing insulation but as Jim expressed, the $ was better spent on things that actually would improve the environment and decrease my electric bill. Koala's pricing was very competitive and affordable. They crew that came in on install day was professional and neat. We noticed a significant improvement on noise reduction (which was not something I thought about or expected). The AC is not kicking on and off every 10 minutes like it used to! In addition to the installation of insulation in the attic, Koala repaired a leaky duct which improved the airflow into the home.
I could not be happier with the results and the improvement, the energy savings but most important the attentiveness from everyone I came in contact with during this process! THANK YOU!!!! Check out the before and after pictures :)

I had an incredible experience with Koala Insulation of The East Valley! Their team came out today for duct sealing and insulation, and I couldn't be more impressed. They were kind, professional, and patient with all of my questions, taking the time to explain exactly what they were doing.
Exceptional Team: The crew was amazing and professional, making me feel comfortable and informed throughout the process.
Personal Touch: Even the owner stopped by to check on the work, which really shows how much they care about quality.
Trustworthy Service: Bill and his brother are clearly good people. After dealing with so many companies that just want to squeeze money out of you, it's refreshing to find a team that treats you with genuine respect and integrity.
I'm so glad I found them and highly recommend their services to anyone looking for honest, high-quality work. God bless this entire company!

I had Koala Insulation Company provide evaluation and installation of blown-in insulation yesterday. They also installed vents and a solar attic fan. Fernanda and his workers were so protective laying plastic everywhere and when they were done, their clean-up was super detailed. They took photos of before and after along with photos of the roof vents and fan. I am so pleased with the results. I can even tell a difference in some of the more warm spots in my house. Kudos to their excellent work and information about the process.

Koala Insulation was excellent. They did an fantastic job start to finish. When they came for the initial estimate they were very thorough and went over alot of different options. They were not pushy with the upsale at all of extras and add ons . Just presented all the options. When they came to do the job they were very quick and did a great job cleaning up afterwards. I didn't even know they were there. Price was very competitive that was the main reason i went with them. I would highly recommend

Bill came out for an estimate work I thought would be needed, but after he inspected the attic the amount of insulation was less than it should be. Compared to others that had also inspected the attic, he show me three areas of concern - one area was void of insulation. My immediate vibe with Bill is this guy is honest and cares about his customers and the work. Long story short, he was able to schedule me in a few days. The price was fair and far below that of two others that had also inspected my attic. I recommend Koala of the East Valley to anyone reading this. I did get their names, but the two guys who came and completed the job had the same demeanor and vibe as Bill. You can tell it is a good company to do business. Thank you, Koala earned every star given.

I want to express my respect and appreciation for Bill Villani and Koala Insulation of the East Valley. After hearing their radio show on how attic performance affects home energy use, I scheduled their free attic evaluation for a home I had just purchased. With a background in building energy performance, I found their explanations on the show to be grounded in solid, proven science.
Based on what I expected to find, I assumed Bill’s inspection would lead to a proposal for a few thousand dollars in insulation or ventilation upgrades. Instead, he showed clear photos demonstrating that the attic already had ample insulation and ventilation, and he explained that no work was needed. That level of honesty is rare and speaks clearly about Koala’s integrity and business ethics.
It’s refreshing to encounter a company that prioritizes accuracy and transparency over making a sale. For anyone concerned about attic health or home energy efficiency, Koala Insulation has earned my trust. Thank you, Bill, and the Koala team.

Koala insulation completed our home attic insulation upgrade recently and we are extremely satisfied with the price and quality of work. We were able to take advantage of two SRP energy efficiency rebates which reduced our cost significantly. The real test will be a comparison of last years summer cooling bills with this summers upcoming bills but we are confident we will see improvement. Work was completed quickly and post work cleanup was done e nicely. Before and after photos included.

Upon hearing from my HVAC company that I needed insulation and duct replacement at a very high cost; I decided for a second opinion. I decided to go directly to an installer to get a second opinion and compare pricing. WOW is all I can say! Not only did I NOT need any duct work, the pricing for the insulation job was a third of the price! Koala had 5 star reviews and completed the job quickly, efficiently and left my home spotless. From the first time I contacted them to completion, the process was what one would expect from an excellent company; not something you find too often these days!
Thank You to the owner, Bill, who came out personally for the quote. You run a great ship! I also appreciate the fact that Koala is a local family run business. Fernanda who apparently runs the front office gave me the confidence I was in the right hands. The 2 techs that came for the Job; Kevin and Ryan were quite efficient and very courteous.
Thank You again!

Bill inspected my attic space and discovered that my AC unit was blowing cool air into the attic from a torn seam. He demanded to come back the next day and repair it at no cost. Because of this action, we selected Koala Insulation for our job. After discussing our options we elected to use foam. The owners Bill and Jim were very professional in completing the work. I highly recommend them.

TLDR: High Quality, Professional, Excellent Value. Highly recommend.
I called Koala for a quote to add insulation in my attic due to high AC bills. Bill Villani came out and did a thorough inspection and evaluation of my home, existing insulation levels, asked about hotspots in the house and even asked how long I intended to stay in my home.
He recommended several options, including sealing of ducts and ventilation options as well as handling the SRP rebates. I ended up going with Koala because of this superb experience, competitive rates, and highly skilled and professional demeanor. I had other quotes but their attitude was more of a “we’ll blow in insulation”.
Ryan Villani, Mike Brouse, the Operation Lead, and another tech (didn’t get his name) were all excellent to work with. They came out on the day of install and were fast, efficient, professional and qualified. They completed duct sealing, O’Hagin vent installation, and blown-in fiber glass to R-49 rated standards - all in under three hour from start to finish. They even fixed a missing dryer vent cover missing from my roof - at no charge!! This is the kind of extra care that differentiates them from other companies.
I would HIGHLY recommend Koala insulation.
If you’re on the fence about which Arizona insulation company to go with, just stop searching and go with them. You won’t be disappointed.

After a thorough inspection, Bill share multiple options to improve our air flow and insulation. He was professional and informative! After making a decision, we were quickly scheduled for a time that worked well for us. The installers arrived promptly and worked efficiently. They shared lots to pictures to share the quality of work they performed. We are also so happy that we went with a solar attic fan to help cool the air in our attic. Something we learned about from Bill and appreciate his knowledge. We would highly recommend Koala Insulation for anyone who is looking to improve their home's efficiency rating.

We just had spray foam insulation done, and I can honestly say we’re so glad we did it. After getting a few quotes, we chose Koala Insulation because of their great reviews and how easy and knowledgeable Jim (one of the owners) was to talk to. Their price was right in line with the others, but their professionalism and expertise stood out.
Our attic was a bit tricky, but they handled it really well—from the insulation removal to the final spray foam, they took great care of everything. Even better, they were super respectful of our home and really kind to our family.
Huge thanks to Ryan and Mike (techs), Sean and Gabe (spray foam), and Noah (drywall). And a special shoutout to Jim and Bill—great guys and great to work with. It’s already been a few warm days and we’ve noticed a real difference in comfort. Highly recommend these guys!

Really enjoyed their work and the crew. Thank you Koala!

We are new to the area and on time constraints. Bill came over from the Lowe’s referral. He spent considerable amount of time in the attic with those documents photos of our newly purchased hose with insufficient insulation. He advised of additional insulation with two solar attic fans.
His crew came in a few days and complete all the work in one afternoon.
We appreciate Bill knowledge and professionalism.

Koala Insulation did a fabulous job on providing our attic with additional insulation and installing a solar powered attic fan. Bill, the owner, provided us with an honest assessment of our house and recommendations. Simeon and Ryan did the insulation installation and over saw the roofer who installed the fan. They were both great! All are very friendly and dependable! Would recommend without hesitation!

On the scheduled service day, the technicians, Simeon and Ryan texted me to let me know they were on the way. The job entailed increasing the insulation in the attic from 3 inches to 14 inches, and also adding a solar rooftop exhaust fan, to cool the attic temperature on hot days. The guys arrived and went straight to work. They ran a blower hose from the truck up into the attic. They carefully covered handrails by the stairs with blankets to prevent any marks or abrasions. Some of the areas in the attic were very low and hard to reach so they had to carefully crawl forward to feed the hose up to reach those spots.
While they worked on adding the fiberglass insulation, the company roofer arrived and installed the fan. It is just to the left of the skylight in the attached photo. It is low profile and nicely matches my skylight and solar panels.
The guys marked the attic with insulation depth, rulers, and took photos to show the before, and after insulation thickness. When they were finished, they cleaned up any droppings from the attic door. I came upstairs with the vacuum, but did not need it because they had cleaned so thoroughly.
Overall, I am very happy with their professionalism, and with the finished job. I recommend Koala insulation, and would use them again.

I highly recommend koalas insulation company!! The ENTIRE team is very helpful and personable
I had an AC company who offered insulation and quoted me 2k more than what koalas insulation did as a specialized insulation company!! They were very detailed and gave me all of the pricing options. I was provided pictures of my before and after work and I am super excited to share them as proof of the maxing job that was done
In specific I’d like to thank Meredith, Ryan, Simeon and Jim.

I first learned about Koala when I saw their company name on a list of preferred installers for SRP. Of course, as with any home project, I always get at least 3 companies to come evaluate the job and provide their plan and quote for the project. When a company checks “all the boxes,” for quality, job overview, knowledge, courtesy, timeliness, and price, it makes the decision very easy when selecting which company will get the job. Jim was an absolute professional and just a very genuine, friendly and “down to earth” guy. After selecting Koala, Jim even came back and removed some planks that were in place in our attic and moved them out of the way so that the attic would be ready for his crew when they arrived at the scheduled time. Speaking of the crew, Simeon and Ryan were great! It’s refreshing to see two young men show up to work in a hot attic with smiles on their faces and positive attitudes. When we encountered a slight hiccup (electrical wire that had an intermittent connection inside an electrical box in the attic), they patiently worked with me while I accomplished the electrical repair so that they could finish the insulation installation.
Koala provided the forms and documentation for the $600 SRP rebate, and applied that credit immediately to my invoice, even though that meant that they will have to wait for the reimbursement from SRP. The insulation looks great and they actually added an inch or two more than promised in most areas. On a side note, Jim also suggested that I replace one of my passive turbine roof vents with a positive exhaust solar powered fan to help evacuate the hot air from the attic. That replacement and installation was also accomplished during the visit, and I couldn’t be happier with the results. Now our attic doesn’t feel like an oven, and the interior of our home is much more comfortable. Our air conditioning unit doesn’t run nearly as much as it did before and I am already seeing a noticeable difference with our electric consumption, even though we are still experiencing temperatures of 112° here in the valley in August. In summary, I am very pleased and I would highly recommend Koala for your insulation needs.

I used Koala Insulation to insulate my attic with blown in fiberglass in my 1,300 square-foot home. Bill, the franchise owner, came to my home, inspected the attic and provided me with a competitive quote. In just three business days after I approved the quote, Koala sent a team to my home to install the insulation. Simeon and Gabe arrived on time and worked expediently and professionally. They insulated my attic to an R – 49 factor (18+ inches) and provided me with before and after photos. Prior to their work, my attic was insulated to an R – 17 factor (5 inches of cellulose insulation). Thanks again to the Koala team for a job well done, and I look forward to improved efficiency of home’s energy use.
