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"

Charlie's Drywall & Painting
Charlie's Drywall & Painting
If it has to do with walls or ceilings - we do and do it well. From frame to finish. Check out our web site to see examples of our work : www.charliesdrywallandpainting.com Hear what our customers are saying and contact us to come and see you project.
"After dealing with many disappointing contractors/handymen, Charlie & Richard were a (shocking) breath of fresh air and worth every penny. This company takes pride in their work and these two men truly want to do the best job for their customers in the long run. They do not cut corners at all and have extreme attention to detail. From the beginning, Charlie was organized, responsive and detailed in his quote. Over the course of 2 weeks, Richard and Charlie were consistently punctual and took great care to be respectful of our home (always used drop cloths everywhere they walked, swept/cleaned up after themselves daily & used the proper machines/filters so dust wouldn’t end up all over our house). The painting and drywall repair came out beautiful! I only wish I found this company sooner, but we will definitely be hiring Charlie & Richard again!"

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."

"Berry Mechanical installed a $10K HVAC system a little over 4 years ago. They are one of only 3 American Standard dealers listed in my area on the American Standard site. All are roughly the same distance -Berry is actually second closest. They are now telling me they will no longer service it because it is too far away. I can understand if they were no longer wiling to do service calls on systems they did not install because of distance but they were more than happy to take the money for the large installation and it was fairly recent. I was paying them every year for semi-annual service and now I have to scramble to find an American standard dealer who actually will travel the same or more distance and will provide service for a system they did not install and may or may no be familiar with. Very disappointing, I can not recommend buying a system from a company that will not service what they install, especially when they are no further away than the only other 2 dealers."

"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!"
