"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"Homeland insulation had the best price among the 4 estimates that I got. Mike obviously knows about house construction, as he was able to tell me things about my house that I did not know. For every issues that I posed to him, he came up with a workable and cost-effective solution. Mike inspected the entire attic and meticulously sealed all floor penetrations by pipes, flues, lighting & fan fixtures including 14 recessed lights. He installed baffles to insure ventilation after insulation. After Mike has blown in the insulation, we had close to R60 (or 20) evenly for the entire attic. In addition, Mike built a hatch above the garage at my request. He did all of the above with obvious competence and with a pleasant customer-focused attitude. I do recommend them."

"I think they did it all in one day. When we decided to go with them. We have one room that doesn't have a second story with recess lights. That room is fairly new, we put it in 6 years ago. He showed me pictures of stucco in there. All those lights were coming in through those recess lights, they were not properly caulked or insulated, so we were losing a lot of beautiful energy through those recess lights. He corrected that. He correct where some of the baffles were covered. He brought it up to high lighting. There was a giant antenna laying across the top of the attic in the main house doing absolutely nothing. They broke it up and removed it. I felt like they were my eyes and ears going up there, something I couldn't do and showed me things that were done incorrectly.  The original insulation was a bluff. It had been displaced. I actually had ceiling drywall in between the structure. They corrected it all. Even the ceiling access was properly insulated and closed. They are just very thorough. They helped us when they troubleshooted from the old company. The price seemed perfectly fair, they didn't try to sell you a cheap product with a cheap price. It seemed like a fair price in line with quality. That's all we really want."

"They did an excellent job on the siding and windows. There were a few issues regarding the roofing they ultimately resolved. They were very professional and courteous during the entire process. I interviewed five companies and was very happy I hired Sunshine for the project."

"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process.  When we called Bill and Contractors Unlimited, they were extremely responsive.  Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others.  Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes.  CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house.  They even saved more than we thought which really reduced our overall expense.  Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation.  At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home.  I would gladly recommend Contractors Unlimited for asbestos abatement.  I just wish we had called them before the floor guys  created such a disaster.  Thank you Bill!

Insulation FAQs, answered by experts

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

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.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.
