"We had a great result using them.  I originally called because of an issue in a room with a bay window - it was very cold in the window, as though they didn't insulate properly underneath.  They offered to come in and do the energy audit.  Their recommendations were reasonable, and included a fix for the bay window insulation issue.  There was no "hard sell".  Their estimated savings for implementing the improvements were $1700 / year.  We had the option to finance and roll the costs into our PSEG LI bill, or pay up front (and get a small additional discount).
I've recommended them to others, who have had similar positive results.

"I researched and found Devon and his company were very well reviewed and he was great on the phone. We have a 1904 home with vermiculite and old batting for insulation in the attic. Devon came out to the house and was planning to do the removal of the old insulation but the vermiculite was determined to have asbestos, so we had everything in the attic remediated. Devon told me about the ZAI Trust and I was able to submit a claim for the abatement and reinsulation. Devon also discovered that a small roof off the kitchen/dining area was uninsulated as well as the dormer roof and the ensuite below it. We had to reschedule suddenly due to Mum being admitted to the ER, and Devon had no issue with this at all, and was very supportive. Devon and his team did an amazing job! What great people! They worked so hard and the spackling job to cover the holes was terrific. We just primed and painted. Devon will be back here to review the insulation status in the rest of the home, as the old foam insulation may need to be supplemented. I'd hire Go Go Green Insulation in a heartbeat and have already recommended them to a couple of neighbours. Old home, apt. or new build, these guys are the BEST!"

Insulation FAQs, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.
