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."

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!"

"First off the furnace was running fine it was a schedule yearly cleaning. Tech showed up on Friday morning service furnace. Wife and I left came home Sunday at 1 pm to a house at 40 degrees. So I removed my furnace door to hit reset. When doing so I noticed my nice washable filter that the technician said was perfectly fine thé year before and explain no need to replace it and took time to show us how to wash and clean it. Well this year the technician took it apon him self to take my filter and he tapped two cardboard filter together with duct tape looked like a first grader did this. So unprofessional. So after hours of sitting in cold because the rester didn’t work and apparently you can not speak to any one who speaks English at the call center a tech finally came out changed everything the first tech did but installed the proper fuel nozzle then had to reset air fuel again after the correct nozzle was installed. I showed him the tape together filters and he was surprised. I have since tried calling to get my filter back called as many as 7. -10 time and promised a super visior would call back never got a call. Also asked for a bill with the list of parts they changed never got the invoice. A week before I called about central air and quote well this guy was late because he had to pick kids up at school. He showed up goes out in truck comes back in two quotes one for 82,00.00 and one for 11,200.00 dollars. And all they said was unit number ////: and the price nothing about parts used or labor just install central air. So still no call back and I will not recommend them to any one and when someone ask about them I will describe our dealings and strongly suggest them not to use them and will never say a good thing about them. They suck"

"On Sept. 26th, we had our shower looked at by Al Romano. Al was prompt, on time and did marvelous work on the shower making adjustments and cleaning things up. Al was very professional and explained all questions we may have had and answered to our satisfaction. This is the second time Al has done work for us for the shower and had the same results, very professional and very well done. You can tell, and see it, that he is very conscientious and meticulous about his work and what he does and it appears that he is doing it as if it was his own (shower). IF we have any other issues with it I would prefer that New Pro send Al Romano out to do the job. Certainly Al deserves a bonus for his work. Ray Fournier"
