"Bottom line: I would hire this company again. Koala Insulation came and inspected my attic spaces with a infrared scanning tool. They looked at the level of insulation and found areas where the heat was penetrating more. They recommended specific actions and gave me a number of quoted options on the spot. I was then able to book the service within days of the initial visit. The technicians came and performed the service professionally and made sure to involve me where needed. I would hire them again."

"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."

Insulation questions, answered by experts

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.
