"We couldn't be more pleased with the added insulation in the attic above the garage. Only downside is that it's better done than the rest of the attic! The rest of the work replacing the insulation in water-damaged areas went very quickly. We will likely be bringing them back to do the rest of the attic."

Top notch. Stop looking--this is the company for your insulation needs."

"I live in a old house, and the insulation on the attic needs to be added.  City of Austin Utilities (Austin Energy) has a great rebate program for insulation, so I signed up.  EnergyAttic is one of the companies listed by Austin Energy.  For getting the quote, the audit person was friendly and through with his explanation about what's and why's.  Finally I scheduled for the work.  Kent came with his crews and basically supervised and worked on the problem and the insulation.  He made sure everything was installed (seal, insulation) properly and Austin Energy auditor approved the work.  The door blower/blast test took a while because of setting issue (EnergyAttic subcontracted to other company), and finally after 3 hours, we did get an excellent result.  I was happy with Kent's and his crews work.  They were friendly, punctual, and got the work done.  They actually came back to reseal door on the furnace area.  They also promised to come back if  I were to work on the attic and the insulation needed to be re-sweep."

"While this company was backlogged when I got on their waiting list the skill and professionalism of their team was well worth the wait.  Not only did they go a great job on redoing a roof that someone else had screwed up over the summer the managed to leave our yard cleaner than when they arrived.

Forrest was extremely responsive. I called and he was able to come by, I believe, the next day to an energy audit to determine why my electric bill was outrageous and the temperature varied throughout the house. Right away he determined there was virtually no insulation in the attic (easier said than done considering the dark,  3 ft crawl space filled with giant metal ducts) except what was left from the original install in 1975. I was able to schedule to have the work done in about 5 days. I'm not sure if the price was good or not but I really liked Forrest and he was available to get the work done ASAP...that made it the right price!  He and his crew arrived when they said they would, blew in the insulation, mended ducts, expelled all the critters in the attic, and replaced the broken booster fan blocking the air going to the opposite end of the house.

I also texted Forrest Friday with concerns that there was hot air coming out of the vent when the AC wasn't on, he said he could be there the next day to check it out. He showed up when he said he would, determined that coincidently, I walked under the vent right when the AC turned on and all the hot air was being pushed from the duct.  There was no issues other than my bad timing.

I will continue to use this company for everything and anything they can provide that I need in the future.

"I had some water spots in my sealing near some of my air ducts, so I thought I had a water leak related to my AC. Henry came out right on time and did work to show me that the leak was likely from my shower line. He didn’t even charge me for that work as it was not in the scope of stuff he normally does! He suspected that I might have a Freon leak my coils, and when he couldn’t find a major one, we checked outside, and when that didn’t show a major leak, he recommended I call him Back and he would personally come back out when the temperature was hotter to get better pressure readings. I have very high standards for service and integrity, and Henry greatly exceeded both."

"This company is willing to go the extra mile for its customers, literally. I've been trying to get foam insulation put under my floors for the last 3 weeks but with the first two companies I hired something always came up or they would have an excuse with why they couldn't do it. But with Eco Foam, I do admit they did have a little mistake in the morning but I called Scott and even though I was extremely rude and short with him, even though he didn't deserve it, he never lost his cool and was able to come up with a plan to get my project done. Most company's would have told me where to go and hung up but Scott didnt do that. He instead drove the 2+ hour trip to be here with his other rig and got the job knocked out so that I could finally put the house on the market and have an open house the next morning. For that I am EXTREMELY thankful and will only use them for my insulation needs as well as recommend them to my friends, family, and colleagues. Eco Foam is the real deal with an A+ in quality, A+ in performing the job , and an A+++ in customer service. Do yourself a favor and call Eco Foam."

Insulation FAQs, answered by experts

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Minimal, mainly occasional checks for damage or mold in extreme conditions.

Spreading tin foil over your windows works similarly to radiant barrier insulation, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn’t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.
