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"

Welcome; a little about me. My name is Nick, I've been in and out of the construction world for the better part of the last 15 years doing everything from footings, foundations, and flatwork concrete through finish carpentry and paint. I am well versed in vinyl flooring, tile, drywall, roofing and siding, interior or exterior paint, pest exclusion, remodel and renovation, framing, monoslabs and finish concrete, windows and doors, and many more. During this time, I also attended college for architectural design and development. I have recently decided to stand on my own with the possibility to grow something for the future for my children who all want to learn the trades as well. I am available for quotes and am willing to work either at time and material or bid by the job. I will be uploading and adding pictures of recent work to include the project I am currently working on, which is exterior paint of 140,000ft in grey&black. Although I live in Oxford, ME; travel for work isn't and has never been an issue. I am competitive on pricing and available to work around a budget. The work performed by me can be billed out at time and material or an overall bid cost to suit your financial needs.

AEPs are interior window insulating panels and can be installed in any building –office, home or industrial. AEPs have a higher insulation and air sealing rating and provide greater comfort than most replacement windows, yet they are a fraction of the cost. AEPs are custom made to fit over existing openings, protecting, preserving and improving your existing windows.

Insulation questions, answered by experts

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. 

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Yes, you should insulate your PEX pipes if you’re wondering how to keep water pipes from freezing. Pipes in uninsulated rooms or outside the house should always be insulated. If you’re looking to save money, you may not always need to install insulation on PEX pipes that are running through interior walls with insulation.
