"Kyle, Nick and the team have done a great job adding insulation to our attic (and even removing some bad stuff). Good communications, (Josie provided e-mails) discounts, attention to detail, promptness, neatness by covering floors with plastic and vacuuming when finished. The pictures were a great help as well. The invoice was "as bid" with no surprises and provided various payment options. We did not mind these guys being in our home! This company understands how to do business responsibly."

"Excellent work, competitive pricing and hard working staff! After initial consultation Mauricio gave me multiple options of insulation level for my attic to bring it up to date and/or blow in additional and that's what's I decided to go with. On the day of appointment their team got right to it and figured out best point of entry and only took a few hours to complete the job! They come with a special ruler indicator that verifies the insulation is to the level requested, then after a quick clean up they were on their way to the next job with another satisfied customer. Overall a great help and I've already booked them for some additional work in my basement as well! Would definitely recommend C4 insulation for all your home needs!"

Insulation questions, answered by experts

Yes, covering exposed wires is necessary for several important reasons. Exposed electrical wires pose significant risks, such as electrical shocks, fires, short circuits, and potential damage to your home’s electrical system. By properly insulating and protecting the wires, you can minimize the potential for accidents, prevent electrical fires, and ensure your electrical system stays intact. 

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.
