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"

JP Pest Services has been providing pest management solutions for New England homes and businesses since 1925. We’ve learned a lot about our Northeast customer base over the past 9 decades like what they expect from the effectiveness of our services to what they need from our Customer Service Representatives and Service Professionals in the field.

"Joel their sales rep assured us our apartments would be rotated so the inside of each unit was checked at least every six months. Got the bait and switch bc they never did this and we had a cockroach infestation that went on for a year. They lied to me and then their manager claimed “we don’t see it in the contract”. I want a refund. You’ve been doing nothing productive. I can lay my own ant traps for less than $2k a year."

Percival Remodeling LLC is a family run business and has been in business since 2014 serving most of Rockingham and some of strafford counties. We welcome small jobs from changing door knobs, disposal solutions, and branch pruning away from the house to larger jobs such as full remodels, additions, and garages. We carry general liability and workers comp insurance and can provide a certificate of insurance upon request. We take pride in our work and the materials we install. We also offer disposal services. Also, we do not service mobile homes, and we apologize for any inconvenience.

"Reliable and trustworthy from the get-go! He actually promptly returns phone calls! Throughout the project, Kevin proved himself to be hard working and meticulous from start to finish! We have not one critical thing to say! He was punctual, efficient, so easy to work with and, did I already say hard-working??? His honesty and integrity set him apart from so many other contractors, in fact, he just called to say we had overpaid him by $100.00! Wow! My husband and I were very impressed by not only his work, but by his trust-worthy character and the pride he takes in his work. His assistant, Josh, was also a hard worker and showed such attention to detail - he was even careful not to destroy plants in my garden just below the window he was repairing! It was money well spent! We have already been singing Percival Remodeling's praises and referring him to others. We will hire him for all our future construction projects! Thank you so much, Kevin and Josh! We appreciate the excellent job!"

"We were thrilled to have the support of Mr. Garand and his team in rebuilding our bathroom after is suffered water and sewer damage. They did an excellent job for a very reasonable cost. They recommended materials and supplies which improved both the appearance and functionality of the room. He has a great network of support tradespeople who we were able to call on to work on other parts of the home. Mr. Garand and his team communicated honestly and routinely about what they were doing. They kept the work area clean and well organized. They worked with our schedule as much as possible. And, they helped us find some construction materials at a lower cost and of better quality than we could find on our own thanks to their connections. We plan to bring them back for more renovation."

"Lenny and Lisa are great. During the demolition phase, Lenny took great care to cover our hardwood floors and cleaned thoroughly while removing the countertops and backsplash which really helped to keep the dust level down. Lisa recommended vendors for our granite, tile backsplash and sink - they were all so helpful. We have never done a kitchen renovation before and were a little anxious about the process and making choices. Lenny allayed our fears and was spot on with suggestions. Lisa was always available for communication and answering questions. The sub-contractors were all excellent, personable and professional. The whole job was finished ahead of schedule which allowed for our 18 month old granddaughter to come for an earlier visit! Overall we are thrilled with the outcome and will definitely use Apple Wood for future projects!"

Insulation questions, answered by experts

You should insulate ducts in a crawl space if you live in a colder climate or you run your air conditioning for most of the year. Insulating ducts doesn't take too much time or investment and can make a big difference on your electricity bill. While this is more difficult in a crawl space, if any ductwork is being done either you or a professional will be down there anyway. A bonus benefit is since they will be putting off less hot or cold air they'll be less attractive to any unwanted pests in the home.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.
