GreenStar Insulation



 Read what our customers have to say about Greenstar Foam Insulation.

Green Star insulated my attic with their 1/2 open-cell spray foam product.
We had a large attic in newer house that had furnance in the attic. We were getting recurrent ice dams and I learned that insulating with spray foam would solve the problem. I researched the issue in excessive detail including the science of unvented attics, and types of foam to use (open vs. closed cell). I decided, with the help of consultant from UMass that the foam insulation would be our best bet, and after much deliberation decided to go with 1/2 lb open cell at 8 inches for an R value of 30. The next decision was deciding between these products, the most common in the industry is Icynene. However, after much research I learn that most 1/2 cell OC foams are extremely alike, including the product used by GreenStar made by LaPolla. Moreover, icynene has a large cost markup simply b/c of name. What is probably the more inportant factor is how well the foam is applied. I got 6 estimates to spray foam my attic. Five were from companies using icynene, and the 6th was from Green Star. Not only was GreenStar the lowest price quote, they were also the most knowledgable, hands on, and personal company. So I went this them. The day the work was done, the technicians were amazing: punctual, courteous, skilled, and clean. They had underestimated the size of my attic so came back the next day to finish. The job they did was amazing. A few days later we had a foot of snow. For the first time in 5 years; no ice dams. With the rebates currently availiable from NSTAR/National Grid...this is a non-brainer. If you are thinking of foam insulation, look no further than GreenStar (and 5% off if you are a member of Angie's list)

We never imagined that foam insulation could do so much for so little so quickly in our lives.  Our Energy bills are dropping and our house feels so healthy to be in.  Your guys are great, honest and straightforward.  When on-site Greenstar made sure that even the smallest details were insulated to our liking.  We look forward to many happy years in our warm in the winter, cool in the summer home.
 Thank you, thank you, thank you!!!

We will never use any other foam insulation for future our construction projects.  Greenstar operated with the utmost professionalism and understood our needs to insulate the structure quickly, efficiently and even helped out our architect in many cases.

"Our heating bills were over $1200.00/ month last year.  We contacted Greenstar in shear desperation in hopes that we could cut them down to size.  They came by, gave us an estimate and promised us savings of at least 30-40%.  I didn't believe them, but, I had them do the job anyway.  Well, my last heating bill came in at $325.00 I was floored!!!  I have given their name out to all of my neighbors and friends.  if you have any hesitation, I have three words for you....JUST DO IT!!!"

We had mold in our attic and didn't know where to turn.  We called nearly twenty mold removal firms and each one gave us a different solution and all were very expensive.  We finally found a consulting firm ( -we love Sam) who pointed us in the right direction: Spray foam insulation.  There was only one spray foam company with the experience to stop the mold growth in our attic: Greenstar Insulation.  They arrived on-site as scheduled, performed the mold eradication/spray foam insulation and were courteous and attentive the entire time they were here.  They finished the job in about 5 hours and left my house spotless.  All for a price less than half of all other mold removal companies!  We got a big rebate from our gas company and our heating bills are now less than half of what they were last year.   I love it!
