"After a year and a half with my crawlspace encapsulation everything is going good! I was very nit-picky about many details and everyone I dealt with was courteous, professional and communicative, had 1 little issue that was immediately resolved and the techs that got it completed did a great job. I was very pleased with the way they set up a barrier around my pool to prevent any debris from getting into it too"

The install crew of Shawn H and Dustin were prompt, professional and efficient. I would recommend this company and will use them again for my insulation needs."

"Upstairs would not cool down with the unit on, called indoor mechanical and Robert and Josh came out within 24 hours. Did a lot of testing and looked everything over and turned out needed and entire new unit. Had a price same day and an appointment set. They were on time, professional, cleaned and made sure everything was running right and even checked to make sure the kids rooms had good air flow to keep them comfortable during these warm spring days in NC. Could not ask for a better outcome to a crappy situation that is going to happen eventually when you own a home. Indoor mechanical will be my go to for anything they offer."

"My experience was great. Steve kept communications open during a period of inclement weather. When the weather cleared Steve and one of his crew came to access the job and determined that they could do the job right then, so they got to work and installed the gutter with the highest level of professionalism and skill. I will recommend Blue Seamless Gutters to anyone without reservations."

Insulation questions, answered by experts

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

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.

Through R-value assessments based on climate and existing insulation.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

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.
