In Portland, the best types of insulation include fiberglass, cellulose, and spray foam. Fiberglass and cellulose are cost-effective and provide good thermal resistance. Spray foam offers superior air sealing and higher R-values, making it ideal for reducing energy costs in the variable Pacific NW climate.

Signs that your home may need more insulation include uneven temperatures between rooms, high energy bills, drafts, and walls that are cold to the touch. You might also notice ice dams forming on your roof during winter.

The cost of insulating a home in Portland varies based on the size of the home, the type of insulation used, and the areas being insulated. On average, homeowners might spend between $1,500 and $4,500 for insulation projects that improve home comfort and lower energy costs. Attic insulation tends to be less expensive than wall or crawl space insulation.
Important to note, there are often rebates and tax incentives — including the Energy Efficient Home Improvement Credit (Inflation Reduction Act) that can save up to $1,200 each year on professionally-installed insulation materials — that help lower your total cost. As part of our service, we do all we can to help you capture the savings for which you are eligible.
Yes, proper insulation can significantly reduce energy bills by improving your home’s energy efficiency. Insulation keeps warm air inside during the winter and cool air inside during the summer, reducing the need for heating and cooling. Homeowners often see a noticeable reduction in their utility bills after upgrading insulation.
The R-value measures an insulation material’s resistance to heat flow; the higher the R-value, the better the insulation’s effectiveness. In Portland, recommended R-values are R-38 to R-60 for attics, R-13 to R-23 for walls, and at least R-30 for floors. Choosing insulation with the appropriate R-value ensures optimal energy efficiency and comfort.
Insulation can last for decades, but its effectiveness can diminish over time due to factors like moisture, pests, and settling. Fiberglass and cellulose insulation typically last 20-30 years, while spray foam can last much longer. It’s recommended to check insulation every 15-20 years or if you notice signs of deterioration, such as increased energy bills or drafts.

What They Say About Us
HomeRx insulation went above and beyond! I highly recommend using them for spray insulation. From the start to finish they were amazing to work with thankyou so my for the help homeRX !

Workers were very professional and clean, and now the house has proper insulation in the attic for the first time in its life! So exited to have warmer winters and cooler summers

Our whole experience of working with Home Rx was great. From the bid to the completion of the work. The timeline was quick and communication was great.

Home RX was a wonderful service for getting insulation blown into my attic. Aaron was the rep that came out to give me an estimate. He was excellent and explained everything so well. Thank you so much for a great service.

I had an insulation job in my attic. The project was inspected by Nelson Gomez a very nice who explained to me in details about the work needs to be done in the attic. The whole crew were very courteous very on time and the project was completed in a very nice manner.

HomeRx provided an excellent service installing foam insulation. The team was organized, timely, and completed the project without concern. I’d highly recommend.

The crew was very professional and completed the project as planned. I would highly recommend Nilson and his crew.

HomeRx installed the attic insulation at a difficult site to spec, professionally, on time, as bid and left the site clean. What else could you ask for ?

Awesome work!

HomeRX and Maxwell are great. They did two projects for us, full upstairs and downstairs insulation with different products suited to each space. Then later they came back to do the attic where we had minimal flooring and shallow rafters so we didn't want to risk doing it ourselves. HomeRX are responsive, fast and good value. We passed our inspections no problem and you can feel the difference in comfort. Highly recommend.

I got tired of my cold house, so I decided I'd insulate the attic myself. I planned to tear out the old insulation, and install new rolls. Estimating that I would have to remove about 200 garbage bags of insulation alone, I figured it would take the rest of my life to complete the job. I had to come up with a new plan... I heard about the Smart Grid Test Bed collaboration, a PGE program which through their incentives would pay part of the cost, and from their website, learned about Performance insulation (HomeRx). So in February of this year (2025) I called HomeRx, and Bryan came out. He looked around, and later gave me a proposal to which I agreed. About a week later, work started. Jesús and crew came out and made short work of it. They removed the 70 year old roll and blown-in insulation, and then blew in ~18'' of new fiberglass, all in two days. Two. Ahhh...finally I was warm. But I wanted more... I had them insulate the walls. Next month they blew in cellulose insulation all the way around. Again, in two days. From start to finish, office and field crew, good job everyone. Attached are some pictures showing the truck with the bag that holds the vacuumed out old blown in, and on the lawn, the removed old roll insulation. Also shown are the suction/blow in hose running through the living room, and before (pink) and after (white) pictures of the attic, and also the wall insulating in progress.

Home Rx went above and beyond.

HomeRx recently completed a full replacement of the insulation and vapor barrier in our crawl space. This became necessary after raccoons damaged the existing materials by breaking through a foundation screen vent. I was impressed by HomeRx's professionalism, particularly their clear and comprehensive estimates. The work was performed with great attention to detail and in a consistently clean and safe manner. Any unexpected issues that arose were promptly communicated and resolved without hesitation. I would certainly use HomeRx again should the need arise in the future.

Great work. Great service. Nice people too. Don’t often say this but would definitely use HomeRx again and recommend them to anyone.

Outstanding people outstanding job. Thank you very much. I would definitely recommend these people to all my contractors.

Home RX provided insulation at my mother’s house as part of a repair for a roof leak. I had used them previously at my house and recommended them to her. They did an excellent job and were very customer oriented. I would recommend them to anyone in need of insulation services.

The crew made it very easy to work from home while they took care of replacing my old insulation with new. They even came in at half the price of my original company of choice.

I really appreciate the job that Home RX did blowing insulation into the walls of my 112-year old home from the outside. Some other insulation companies were reluctant to do it because the house has the original wood siding, but Home RX took it on and did a good job. It took them considerably longer than anticipated, but they stuck with it and didn't charge me more. The workman were considerate and cleaned up every day. Nelsin, the salesperson, was responsive to questions and phone caalls, and patient when it took me a while to collect estimates and make a decision. I would definitely use them again.

HomeRx was a pleasure to work with for my insulation needs. They were professional, prompt, and personable. The communication was great and the quality of work was as well. I would not hesitate to use them again and I highly recommend them to anyone else.

I'm so happy I found HomeRx it was useful on many levels! From the communication to the bid, to the actual work and the final payment, everything was easy to understand and all of the people were helpful. The insulation work appears to be well done and the cost was minimized by use of incentives from the Energy Trust of Oregon. Thank you, HomeRx!

We were very happy that HomeRx came right away to asess our damage after our roof leaked on Christmas day. They gave us a good quote and started work in record time. When we had a conflict in scheduling they worked with us and finished up on time.

Very professional service! Timely response to my request for a bid, got a great quote, scheduled the job. And the team was friendly, on time, explained everything, took care of my house beautifully, and cleaned up well after. Worthwhile to pick this company!!! The whole process was smooth, upfront price, and excellent quality job. I should have done this sooner. My electric bill has already seen improvement! 2 thumbs up!!!

HomeRx and their crew did an amazing job on my dog training facility building over at k-9nation. They showed up on time and finished in one day. The owner was out there the day after I called for an estimate. I spoke with several different places but I know I went with the right company. Highly recommend HomeRx.

Your employees were so polite and professional. We are very pleased with the job. Thank you so much

Over all great experience which Home Rx. Fast to come out for a quote. And fast to come out and install. I had the attic and my exterior walls done. Very please.

Neilson and the team did a great job. Communication was good and the guys in the field worked hard to get it all done.

Great work! They insulated my large walkin attic and I am very happy with the quality and the price. It wound up taking longer than the initial estimate but they stuck to the agreed price.

House is now warm. Great service. Nice workers. Five stars.

Very professional and great work. Helped me save money and got way more in the end. Highly recommended.

I called HomeRX to address our insulation issues. Already we paid thousands to another company but this old house was drafty and at 57 degrees Fahrenheit very cold. Abraham and Saoul showed up with the Blower door test and we could feel and see, where the air went out. The number for the house were very high. The crew went to work and “air sealed” our home up side down. Within two days our house felt cozy with normal temperatures of 65 at night. I had lots of questions and Abraham was the best in customer service. BTW: Compared to the other company, they were very reasonable.

I was in a time crunch to get spray foam installed on a bdrm remodel. Had estimator arrive on time. Price was as expected after my research. It was approx. a 2 week wait for appointment but I was on waiting list for cancelation. Got an appointment, crew arrived. This is where I was impressed. The 2 man crew, Eleazar Caal & Yony Matias assessed the job. Set up plastic to protect everything, wires, plugs, lights, floors even signage for the public. The job was perfect for me. Scraped overspray off all studs for my sheetrock and a great cleanup job. I would definitely use them again & request the same 2 employees.

Easy to work with. Great value and much better insulation than we had before so happy customers 😃

HomeRx is the third insulation company I've used in the Portland area and the only one I call on for more projects I need help with. They are flexible with schedules and do very detailed work, and the guys on the job sites have been great. Add to it all very competitive pricing, and you have the insulation company you need. I highly recommend them!

We were very happy working with HomeRx in getting an insulation upgrade for our home. Nelsin was great to work with and provided a very detailed bid for separate parts of the job. The attention to detail helped separate his bid from others. And the installation crew were awesome, working very hard in our very tight crawl space.

Had HomeRX install a vapor barrier in my crawl space. Guys were awesome. Arrived right on time, worked super-diligently, cleaned up and finished the job very professionally. Could not be happier with HomeRX. Highly recommend!

We contacted HomeRx for an estimate on our attic upgrade. Our initial contact was Nelsin, who was outstanding! He was very thorough in acquiring the information needed and explaining the process. He carefully inspected the attic and discussed his findings with photos he took! He offered several options to proceed and finalized our estimate that same day. Nelsin was easy to work with, knowledgeable, and professional. A crew arrived several weeks later to do the work. It was during a heat wave. They were very careful and stayed safe, going above and beyond to make sure everything was done perfectly. The effects were immediate and amazing! We are very satisfied customers and highly recommend HomeRx.

Everyone was great to work with, answered all our questions, and did a thorough attic inspection including pictures. Scheduling was easy and everyone showed up when they said they would.

Great work, great communication! 10/10

I found there estimate to be very comprehensive compared to other vendors. The installation was expertly done with good follow up from the main office.

Stephen came out explained what they would do and how they did it. He was very thorough and professional in explaining his answers to my many questions. The crew followed up and worked 10 hours installing the insulation and prepping the attic. They did a top notch job just as Stephen reassured me they would. Thank you!

They did a fantastic job for a very reasonable price.

Happy with our experience. Competitively priced and good service.

This company has integrity! They worked until I was satisfied and that is rare these days. I highly recommend them!
