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"

"The service lasted over the course of several months due to the seasons and my building schedule. After meeting with several companies and feeling very uncomfortable getting random numbers with little or no supporting information I was referred to these folks. From the first call all were great. Met with the owner who came out, he explained the process, listened to my needs (RValue, stretch code, continuous coverage throughout) and my plans and schedule for building. They were very responsive and did the roof in the fall and the walls last week. They adjusted their schedule several times to fit mine, completed the project and cleaned up very well. The inspectors are impressed and I'm very happy with everything. I will use again and highly recommend for anyone who needs insulation to give them a call."

Insulation questions, answered by experts

Yes, guiding choices between open-cell and closed-cell foams based on needs.

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.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

Spray foam has superior sealing properties, moisture resistance, and soundproofing capabilities compared to traditional insulation.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.
