"The service was above any beyond what we have experienced from anyone else we have hired. From the initial contact right through to the end of the project their service was outstanding. Gary, Bill, Mike and Joe were true professionals. The proposal we received was very detailed offering several options for the work we needed done to improve the ventilation and insulation in our two attics. We received daily texts letting us know their arrival time, photos of the progress and daily status updates on what was done and what was next. They took great care in covering up our furniture and floors, putting up plastic, etc. They did a great job of cleaning up at the end of each day and their final cleanup at the end of the job was outstanding. Our property looks like they were never here. They did everything they said they were going to do and more. While they were here they found a couple additional items that needed to be corrected and promptly made the repairs. We can't say enough about the outstanding work they did. They will be our first call for any future projects."

"I was really impressed with the quality and professionalism we received from Correct Energy. They gave us a fair price and performed the work almost immediately after the consultation. The end result was unbelievable too. The second floor is usually so hot but after the spray foam even without AC the temperature change was drastic, and it's far less noisy as well. I was also impressed with how well they taped off the walls, floors, and electrical to cut down on the mess afterwards. I didn't have to do any cleanup at all. Would highly recommend this company and we will be using their services in the future for subsequent projects."

"THESE GUYS ARE AMAZING! Our new porch looks perfect!!!! They got back to us very quickly, and after we agreed on the project spec's amd pricing they got right to work. Our old porch was down and our new one was up in just a little over a week. They were even able to repair our leaky side roof! These guys were friendly, professional and very neat. They also offered us financing options which was to have. I would recommend these guys to anyone looking to have some home improvements done! We will totally be using them again!!!"

"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

Insulation FAQs, answered by experts

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.
