"We moved into our house in the winter and found out that the 70 year old insulation was quite deteriorated and moldy in the fall. We decided to have the old insulation removed so that we could cut down on heating bills and get rid of the smell. I contacted several companies and interacted with Joe from Good Life as the salesperson. He was kind enough to come to our house twice as the scope of the project changed. Both times, he drafted the proposal right at the end of the visit. His professionalism and the quoted price convinced us to go with Good Life Energy Savers. On day 1, the first crew came to remove the old insulation from the attic and used open cell spray foam to insulate the basement rim joists. On day 2, a second crew came to apply blown-in fiberglass insulation in the attic. Please note that the material they use is not irritant at all. Both crews worked really hard and cleaned up very well after they were done. I was especially impressed with the job 1st crew did to remove the old insulation from the slopes on a cathedral ceiling. My only minor complaint is regarding the patch in the ceiling at the end of the job. The guys used paper tape and there were bubbles all around. I guess they were very tired at the end of the day. Initially, I was planning to paint the room myself to cover the patch. But after removing the paper tape (due to bubbles) and using fiber mesh tape and joint compound, I figured I wouldn't be able to smooth the edges of the patch perfectly and hired a professional. Overall, it is a great company that provides quality job at a reasonable price. With the new insulation, the furnace runs much less frequently and I am pretty sure the job will pay for itself very in a few years."

"Workers showed up promptly and were very professional in establishing a clean work space by putting down plastic all throughout my upstairs. The workers were great in getting the job done correctly. I had removed all of my interior walls for them to spray into the walls and they made sure if i was placing new sheetrock to scrape the insulation down to the joists. However, I did not like that the owner did not show up as he was the one that gave me the estimate and then I had to relay everything we spoke about to the workers. Also, I placed a great deal of plastic on my floors in the basement and after the workers left I had to clean up areas where foam was sprayed onto my rug. Most of it would not come off. I would have hoped better cleanup would have been done. In the end, the two workers did work very efficiently together and completed the job to my utmost satisfaction.

"Joe did a great job on this, our dining room was a add on to connect the original home and the garage and had no insulation and boy in the winter it was unusable as well as the kitchen basically (the best part of the house). Joe came and drilled small holes in the attic floor that they sealed up later to allow for blowing in the insulation. And they cleaned up well. we have a 20 month old but there was nothing left over for the baby to put in her mouth. Joe is great! Our dining room is toasty and the kids can play in there year-round Plus they are were less than half of the expensive "efficiency" guys PSEG sent over. Those providers wanted to charge $10,000+ for basically the same job."

He explained everything simply, and gave us clear choices, recommendations, etc. He shows up when he says he’s going to, responds when you reach out, and did a great job on the projects we hired him for. We would definitely use him again, for insulation, renovation and repairs."

"Absolutely I would use this provider again, as a matter of fact just recommended them to a friend of mine and actually to quote her text message she sent me on Tuesday "Just had the door installed, love it, love it, love it thank you so much for the recommendation.  I'm telling, their a phenomenal company.  Their service, no, no they really are.  The professionalism of the installers was incredible.  Then the installer put something in to my back, he came by himself, he not only sealed it as much as he could, he gave us his personal cell phone number and said if there's any problem, to call him back the next day.  And this is a guy that's an employee, it's not even, the owner of the company came to give us our price and our measurements and all of that, so initially I dealt with the owner, then I dealt with the service foreman at the office who was punctual, he followed up and gave me details and then the workers that came.  It's just from soup to nuts beginning I have never, and I am calling them back for additional work.  Their workers were professional, prompt, courteous, clean with what they were doing.  Went beyond what they needed to do as workers.  The owner when he came to do his estimate was very explicit in what he was explaining, didn't try to push products on us, tried to work with us,  tried to feel out what it was that we needed.  The support staff in the office was very helpful in making sure that the job got completed in the timely and efficient manner.  I, personally, I mean you called about a good topic because I usually don't have good experiences and this was just, I felt comfortable referring it and the friend I actually referred them to is a very picky type person and she actually had just been finished with another type of contractor  that redid her kitchen and said yeah the job was okay, so to see the message from her going I love it, love it, love it is I am telling you from beginning to end.  Her experience was even, she was asking to have some other jobs done and he was even able to give her decent referrals for other jobs as well."

"They arrived on time. They offered assistance with moving the furniture out of their work area. The workers made sure to cover the floors and all the furniture before they began their work. The work was completed in two days as predicted. They forgot to include one of the entryways ceilings In the contract. I mentioned this to the worker and after a phone call to Ari they proceeded to do the work. Although I would have liked to see Ari at some point during the insulation process, I believe the work was done well. We will wait for this coming winter to give our final verdict.

Insulation questions, answered by experts

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.
