Air Sealing. Feel the Difference.

Air seal your home today and enjoy the benefits for years to come.

Combined with insulation, air sealing improves the overall efficiency of your home. It closes any holes or cracks in your home to prevent conditioned air from seeping out while keeping the cold or hot air outdoors.

At HomeRx, we see firsthand how air sealing can make an incredible difference to the comfort of a home. Our energy audits allow us to pinpoint areas of your home where energy escapes. We’ll offer sustainable and practical solutions to help improve your comfort and save you money.

Air Sealing Services

Air sealing and insulating go hand in hand. They serve as protective layers to keep your home comfortable in any weather.

While insulation acts as a sweater for your home, a sweater itself is not enough to keep the cold at bay if there is any air movement. Air sealing is like a windbreaker jacket over the sweater. Here in the Northwest, we know all about layering!

The air sealing process involves locating the holes throughout your home (even the potential ones) and sealing them up. When combined with the right type of insulation, air sealing makes all the difference in the world in terms of your home’s comfort, heating and cooling bills, indoor air quality (IAQ), and energy efficiency.

What Are Some Keys to Air Sealing?

You’ve probably heard how newer homes can be sealed too tightly, which can create indoor air pollution and cause moisture to build up in the walls and attic. That can lead to a muggy home—your ideal indoor humidity level ranges between 30 and 50 percent.

Years of training and experience have taught our HomeRx team how to do it right so that we do not trap moisture—and allow for drying if moisture finds its way inside your home.

Our air sealing experts know how to ventilate, monitor for gases, and the best ways to pinpoint and eliminate pollution sources. If energy were free and there was no such thing as global warming, we would just put in huge furnaces and leave the windows open all time!

Why Would I Need to Seal My Older Home?

Your home may be very healthy. The wood may be in excellent condition in large part because your home has been breathing for the last 100 years.

But there are a couple of problems here—nobody wants to waste energy these days, and the breathing your house does is very erratic.

Temperature differences between the outdoor and inside air cause your home to breathe. It is likely over-ventilating in the winter when temperature differences are more pronounced. Summer is not usually an issue in our climate because it is usually not so hot out, so we can open our windows.

So your home is hyperventilating on the coldest days, then not enough at other times. The solution is to seal it up very carefully to avoid trapping moisture. You then control the ventilation rate mechanically to get the right amount of ventilation all the time.

Customer Reviews

Bryan and his crew were at our house in December of 2025. We were in a hurry to get insulation installed before 12/31 to qualify for tax credits. They squeezed us in and made it work. The work was done extremely well. They even tried to mitigate signs of a leak until we could replace the roof. We didn’t get the roof replaced until April. Unfortunately a leak did happen before that but their work minimized the impact. Bryan came out to check insulation after the roof repair to investigate at no cost to us. Gave us the all clear, no insulation replacement was needed. The extra work they did, at no cost to us, protected the insulation they had installed. They didn’t have to do this but went the extra mile. Have already recommended HomeRx to multiple friends. Thinking about doing some renovations to our home built in 1950. If we do, we already know we will call HomeRx for that work.

We are very happy with the job HomeRx Insulation did on our home attic insulation renovation project. Our Project Manager, Nelsin was great, he walked us through the different options and explained the renovation process, he also offered solutions that fit our budget. The fact that HomeRx works with the energy trust of Oregon is very convenient. The crew worked hard removing all of the old insulation and debris from our attic space, sealed up everything and then installed new insulation. It looks and feels great! I recommend getting a quote and using HomeRx. Thank you, HomeRx team for all your help!

Keoki Landreth April 22, 2026

HomeRX did an amazing job and went to great lengths to keep our home clean during the messy process of removing old insulation and reinsulating. They found some surprising air leaks and sealed them up to make our old house less drafty and more comfortable. I would highly recommend them!

Brian Stewart February 18, 2026

Nice people, good work, fair prices.

Chris Haines November 14, 2025

Four months ago we had our attic sealed and new insulation installed by HomeRx. They did a great job! We highly recommend this company.

Steve & Anita October 20, 2025

Could not have asked for a more diligent and accommodating project manager than Nelsin Gomez. He offered a competitive bid, was quick to respond to all questions, and his crew did a fine job covering attic air ducts in thick insulation to cut down on heating and cooling costs. We noticed the difference immediately. He has a responsive front office team who made it easy to schedule work and arrange payment.

G.A. Perry October 1, 2025

Home Rx added R49 insulation, more ventilation and sealed everything in my attic. They also added insulation under my floor in my crawl space (there was previously none). They also cleaned everything out (it was filthy), laid down a new vapor barrier, replaced all insulation on my ducts/pipes and sealed everything. There were very fast, professional and clean. I took advantage of all applicable Energy Trust savings (Home Rx took care of all the paperwork) which saved me A LOT of money. The cost to have all this done (and more) was significantly less than the other bids I received and Home Rx actually provided more service and higher grade insulation than what the others were offering. We hear less noise from outside the house and it cools and maintains a temperature much better than before. I look forward to see how things change in the winter.

Kurt Vetsch July 31, 2025

This company was a really great option for me. I used them to install our new water heater. I didn't want the standard one, though. I wanted a more energy efficient heat pump. This company came in, gave a fair estimate and gave some strong discounts. They were on time and professional. I would definitely recommend them for the future.

Andrew Sunada July 29, 2025

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.

Mullins Cindy May 2, 2025

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.
