Spray Foam Insulation Experts

Spray foam insulation is the best choice for insulation if you’re looking to increase your comfort & decrease your energy bills. Spray foam insulation is truly the best option for home insulation and here are a few reasons why. Spray Foam Insulation provides an air barrier due to its ability to fill gaps and cracks. It is also great at staying in the hard to reach areas because of its super-adhesive qualities. Spray foam insulation is also waterproof, unlike fiberglass and cellulose insulation. Water will not be able to pass through the foam which makes it an extremely durable and long-lasting product. Lastly, spray foam insulation is foolproof. Spray foam is sprayed as a liquid and then expands and hardens to fill voids and gaps. There is never any chance for an area to be missed or void to form. Once cured spray foam insulation will stay in place for decades to come and will never shift or settle like fiberglass. To ensure your home has the best insulation available and your energy bills are low, switch to spray foam insulation today!

Benefits of Spray Foam Insulation Include:

  • spray foam works in all areas of the home
  • has a greater R-value
  • acts as an air sealant
  • is waterproof
  • leaves no gaps


Home Insulation Company

All the heat that you pump throughout your home in the winter can cost more than you anticipated. One of the largest reasons for the high bill you see every month is that your home is not properly insulated and the heat is escaping outside. Josh Lowe's Dr. Energy Saver is your Portland expert for all types of insulation including rigid foam, attic, crawl space, blown-in, and spray foam insulation. Wherever the air is escaping we can insulate it whether it be through walls, your basement, your attic, or in the crawl spaces. 

Custom Home Energy Audits

Our goal is to make your Portland home's more comfortable, more health friendly, and less expensive to heat and cool. In our energy audit evaluation, we inspect your home and provide reports on the condition of major systems like the furnace, ductwork, a/c, and insulation. We then check air leakage areas throughout the house to identify weak points where you are losing energy. We then provide recommendations with realistic expectations for energy improvements and offer a free estimate for proposed work.

Water Damaged Attic Repaired in Portland, OR

This Portland, OR homeowner found us online and called to receive an estimate on repairing the water damage in their attic.  While our Energy Consultant was there, he also looked under the home and saw the very damaged, and in some places not even connected, ductwork for their heating system. (see photo)

In the attic, our Insulation Crew removed the damaged insulation, treated the roof deck for mold, replaced the damaged sheet rock, and blew in TruSoft cellulose insulation.  The team also removed all the flex ductwork under the home and replaced it with new insulated flex ductwork.  The client was impressed with our crew’s professionalism.

Portland, OR Home Will No Longer Be Hot in the Summer

This Portland, OR homeowner found us online and called for an entire home evaluation to help uncover the reasons their home was very, very hot during the summer months. They called in the spring to get a jump on it before they had to go through another summer being uncomfortable in their own home.

Our Energy Consultant discovered, in his thorough evaluation of their home, that the attic was the culprit (see photo showing how some of attic was not even covered).  Our insulation crew sealed the air leaks in the attic and then blew in TruSoft cellulose insulation to the R-60 level.  The homeowners were very happy and appreciated the full clean-up that our crew did.

Milwaukie, OR Home Family Room Made Comfortable

This Milwaukie, OR homeowner met us at the Portland home show in February and signed up right then to get a whole home evaluation from us.  Their family room has never been comfortable; they had to use portable heaters, which were expensive, to make it moderately comfortable. 

Our Energy Consultant met with them and, after exploring the whole home, discovered their attic was the culprit!  There was not enough insulation in the attic, and there were no seals around the can lights, so all the air they were paying to heat was escaping up through the lights into the attic.

Our insulation crew covered 13 can lights and sealed around them (see photo) before blowing in the cellulose insulation to an R-60 level.

1957 Portland Home Now More Comfortable

This Portland area homeowner, whose house was built in 1957, met us at a home show and made an appointment. She wanted to make her new-to-her home warmer.  Our Energy Consultant met with her and investigated the attic.  He founds air leakage around ductwork, soffits, and the chimney where air she was heating in her home was escaping to the attic and to the outside. The existing insulation in the attic was not at an adequate level, too.

Our crew sealed the leaks (see photo showing sealing around ductwork) and blew in cellulose to the R-49 level that is the minimum recommended for efficiency. Her home is now much more comfortable.

SW Hamilton St. in Portland
HI, I am not sure this is even possible. We are wondering if it would be possible to do blown in insulation between the two floors of our house. We don't know if we have a crawl space or not. We have a garden level apartment and the floors are paper thin. The footprint of our house is approximately 1600 sq. ft., maybe less because I am not sure how much of that is the garage. Our house is not that energy inefficient, so that is not the aim. Thank you. Please do not call. I don't watch my phone during the day.

Our house was built in 1978. We don't believe any additional insulation has been added. It's probably at R11 and we would like to get it to R41.

Initially, I'd like an estimate on insulating a 1100 square foot vented crawl space. Preferably spray foam under the boards. It's dry down there, no mould, no rot. Ball-park figure preferred before coming out, thanks.

I have a bedroom added onto my house with a crawl space below. I would like to have vapor barrier laid down and insulation added in the crawl space since the bedroom floor gets really cold in the winter. Room size is about 10' by 18' or so.

Remodeling an old home and want to insulate entire home if possible. Some of the walls are not going to be opened up and interested in pumping in cellulose into the wall cavities.
SW Seymour Court in Portland
Our master bedroom on the main floor of our daylight basement ranch home is too hot in summer and too cold in winter. I suspect air leakage from window trim area, possibly insufficient attic insulation, and possibly missing or inferior exterior wall insulation. Our 1956 home has new ducting and late model heat pump, and other rooms in house have ideal temperatures. Thank you.
