Insul Kings is a fully licensed and insured weatherization contractor specializing in weatherization work (adding insulation to home), energy audits, whole house air-sealing, and the installation of various types of insulation for both commercial and residential projects. We are a proud partner of Mass Save & NH Save and are rated in the top 5% of their contractor scoring.

"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"Mike was incredibly communicative and efficient with the service that was provided - I received a response immediately after contacting him and he came to our house within a couple of days for a quote. His team started work within a few weeks as opposed to months, and they were finished within 48 hours - all for a very reasonable price. He would absolutely be our first call if we needed something similar done in the future."

"The job went according to plan and looks amazing. I met with LR Higgins Inc. late winter and we discussed the job I needed done. With the pandemic, the windows and doors would take a while to be delivered especially the custom sliding doors for the breezeway. Eric kept me in the loop the entire time. He updated me on a regular basis to let me know when he thought the product would be delivered and a start date. His crew was informative and very clean. All debris was picked up and swept up. I have used LR Higgins in the past and I keep gong back to them. They do a FANTASTIC job!"

"We Hired Erik 2 weeks ago & our experience has been absolutely horrific. I could write a novel on our experience but I’ll keep it short & stick to relevant information. He does not even file for the proper permits to do the work he claims he can do. My town has already filed a report with the state. He has a long history of this behavior dating back to him moving to Maine from the south where he had another business under a different name. We were extremely lucky to have surveillance in our home & to know our legal rights because not only did he not finish the work & leave us with a huge mess, not to mention more work done than we initially needed… he tried to call CPS & filed a fraudulent report so that it would look like we would be retaliating when we filed for breach of contract. He didn’t stop there. He tried making it look like I was coming on to him & asking for work in exchange for sexual favors when I asked him if he was going to honor his contract. He hasn’t responded to me ever since I let him know I have video surveillance. He did this to a single mom with two special needs kids. Please protect yourself."

FAQs for insulation service projects in South Portland, ME

When choosing a professional insulation installer, consider asking these questions to determine the best fit.

  • Will you address air leaks in my house?

  • Can you provide an R-value (heat resistance) fact sheet?

  • What kind of insulation will work best for my home?

  • How do you handle signs of a water leak?

  • Are you licensed and insured?

  • Can you provide customer references?

The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:

  • High heating and cooling bills

  • Uncomfortable room temperatures 

  • Ice dams on the edge of your roof 

  • Roof leaks

  • Cold floors and walls

  • Freezing pipes

  • Temperature fluctuations

  • Visibly low insulation

  • Noise problems

  • Pest problems

On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:

  • Blown-in: $1–$4 per square foot

  • Spray foam: $2–$5 per square foot

  • Batt: $2–$4 per square foot

  • Structural insulated panels: $4–$7 per square foot

  • Loose-fill: $2–$5 per square foot

  • Reflective: $0.50–$1.50 per square foot
