"The service was above any beyond what we have experienced from anyone else we have hired. From the initial contact right through to the end of the project their service was outstanding. Gary, Bill, Mike and Joe were true professionals. The proposal we received was very detailed offering several options for the work we needed done to improve the ventilation and insulation in our two attics. We received daily texts letting us know their arrival time, photos of the progress and daily status updates on what was done and what was next. They took great care in covering up our furniture and floors, putting up plastic, etc. They did a great job of cleaning up at the end of each day and their final cleanup at the end of the job was outstanding. Our property looks like they were never here. They did everything they said they were going to do and more. While they were here they found a couple additional items that needed to be corrected and promptly made the repairs. We can't say enough about the outstanding work they did. They will be our first call for any future projects."

"THESE GUYS ARE AMAZING! Our new porch looks perfect!!!! They got back to us very quickly, and after we agreed on the project spec's amd pricing they got right to work. Our old porch was down and our new one was up in just a little over a week. They were even able to repair our leaky side roof! These guys were friendly, professional and very neat. They also offered us financing options which was to have. I would recommend these guys to anyone looking to have some home improvements done! We will totally be using them again!!!"

"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

Insulation FAQs, answered by experts

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.

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.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.
