Insul-Kings
Insul-Kings
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
JP Pest Services
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."

"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!"

"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!"
