"We had a freezing bedroom in our house as well as a freezing entry way. Turns out it was above the garage with zero insulation. Mike came out and from the start understood what was creating the issue. Not only he is highly knowledgeable about home construction in general, he was an absolute pleasure to work with and hilarious! The team at Acorn was able to schedule us in 2 days before Christmas. If you were in the North East around Christmas 2022, you experienced that deep freeze that came through. If you want to know if your home was insulated right, nothing like freezing temps to show you. Acorn did a thorough and professional job and installed blown and fiberglass insulation. Our room was toasty with no indication of how cold it was outside. I cannot thank them enough!"

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"The job was very well done. Gustavo and his crew were EXCELLENT. Dealing with the project Manager Taylor was EXCELLENT. One of a kind company. A unique feature that was used for installation was the inclusion of BOTH Sanford insulation and housewrap. I have not had another contractor offer me both of those. It’s always either one or the other. Home Genius is backed by the better business bureau and is a James Hardie certified installer for those looking for one."

"I purchased a multifamily house with 2 stories. The 2nd floor had 1 inch original hardwood from 1920 that laid on the floor joists so you could hear every footstep downstairs and my tenants almost moved out. I hired Cesar to take on a tedious and technical ceiling soundproofing technique for the apartment using RSCI rubber clips, hat channels, insulation, and making the 1st floor airtight. I was so impressed with how he was able to juggle handling my tenant for 2 weeks, compensating for delayed shipping by driving 3 hours to New York and picking up the materials himself to make sure we meet the deadline, redoing 1 entire room at his loss and not charging me for it because the original technique we tried did not work, and listening and working with me to make sure we didn't miss any details that would cause sound transfer (and this was impressive because I am very detail oriented). My tenants moved in and were very impressed by the finished looked of the new ceilings and crown molding. We saw a sound improvement of about 15 STC in both airborne and impact noise. It cut down sound transfer by 2/3 in the 1st floor apartment. I will be adding rubber underlayment upstairs underneath the new flooring to completely block out the rest of the impact noise that transfers from the floor above to the walls downstairs that support it! I'll be calling Cesar and his crew again."

"Kelon from pipeworks did an outstanding job of remediating my attic moisture problem. The whole attic was air sealed and new cellulose insulation blown in after removal of all the old product. He was hard working, neat and explained and reviewed all work with me during the process and upon completion. I would highly recommend."

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.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.
