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"

Locally owned and operated, we are known in Dover, Portsmouth, and Rochester for our prompt service and attention to detail. We specialize in residential handyman services. Customer satisfaction is always our primary concern, so don't hesitate to give us a call today!

"Showed up on time. To look at broken balances on windows. The Handyman unlocked our window sash with out hanging on top window which proceeded to fall down and he broke my bottom stops. It?s been over two weeks haven?t heard anything called five times I?ve given them my email still haven?t heard nothing. So basically I paid the handyman service $88 to break my window and never get back to us. For the simple reason I would not recommend this company. Lack of communication very unprofessional. Not to mention breaking something in your home and not staying in touch to simply let you they?re going to fix it ! They old saying goes first impressions are everything. This left a bad impression"

"We hired Roberto and his team to install drywall in our garage. The work done was great and it exceeded our expectations. As well, Roberto was very accommodating with us when we had to reschedule a start date due to issues I had getting the building inspector to sign off on my prep work. There was one minor issue that happened during the drywall install process, Roberto was able to fix the issue the same day and kept everything on track. He even helped us install a door afterwards. 10/10 would recommend Roberto and his team and will definitely be going to them in the future!"

ABI LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"We chose ABI because we were comfortable with their assessment, quote details, and ability to answer our questions thoroughly. We went with polyiso boards and cellulose as the materials. The price was very fair. The day they did the work, with Flo and Carlos onsite and part of the crew, they were focused, professional, friendly, and careful with our home and belongings. Any hiccups along the way were problem-solved and dealt with immediately. They not only left the inside clean, vacuuming after they removed the runners they brought, but made sure to check the outside of the house and swept the driveway for any small debris. The final check included a walk around the outside of the house. We knew they had to remove the siding to drill the holes to blow in the cellulose, but you would never know that the siding had been disturbed. We would not hesitate to recommend this company to anyone else looking for a fair and honest home insulation company! "

FAQs for batt, rolled or reflective insulation install or upgrade projects in Merrimack, NH

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
