I wish we had called Insul-Kings sooner! Our kitchen pipes kept freezing due to a poor remodeling design. They quickly assessed the situation and completed the job the next day! They were communicative and professional. So grateful!

These guys are superb! After contacting Angie's List, my phone immediately rang and a knowledgeable, articulate, professional Insul-Kings representative asked about my insulation needs, arranged an estimate within a week, and the job was completed the next day. Not to mention that they called to confirm both appointments and showed up at exactly the appointed time. The workers were efficient, polite and very professional. And they cleaned up thoroughly. Best home repair experience I have EVER had, bar none.

We had Edwin and his team at our house, and we are so pleased with the work that was done. We’re already seeing a huge improvement in the heat staying within the house. One of our boy’s bedrooms has always been cold, but less than 24 hours after the service was completed, we noticed the room nice and toasty – this has never been the case during the cold months. The weather strips placed on our doors has gotten rid of the drafts making our large living room (with cathedral ceilings) warmer as well. I had also asked Edwin to take a look at another space that I was concerned about and he took the time to stay and check it out. Wonderful customer service!

Insul-Kings recently completed insulation work in both our basement & attic (after we contacted Mass Save for an energy evaluation). The Insul-Kings team was able to complete their project in a single day - we are happy with their work & would recommend them to others looking for insulation services.

No issues at any point in the process: the quoting process was simple and straightforward, and the installation crew was quick and professional, and the installation itself was done well.

Working with Insul-Kings to fix our attic insulation was an amazing experience! From the consultation to the installation, everyone we spoke to and met was very kind and professional. Every step of the process was clear and the crew did a great job cleaning up after themselves every day of the job. Would highly recommend!

Great experience overall with Isul-Kings. Local business, strong communication throughout the whole process (Multiple options with different price points explained thoroughly, along with finding a date for install), installation was quick and clean and the results were felt immediately in my home. Thank you guys! Highly recommend.

We were contacted by Insul - Kings after going through the Mass save program. Scheduling the work was a breeze and they communicated with us throughout about the arrival time, estimated work hours and what kind of work would they be doing. They arrived right on time with three personnel. To start, they had us close down all the windows of the house and sealed the front door with a fan pulling air to check the sealing of the house. Then they proceeded with checking the CO level and finally started the insulation work. They checked all the doors and sealed the leaky ones. A majority of the time was spent in adding the insulation in the attic. Post insulation work they rechecked the sealing of the house and showed us the number which dropped, showing efficacy of the work they put in. Hardworking, communicative, transparent and easy to work with would be the words I'll use to describe them. Without hesitation, I'll have them if more work is needed in the future.

"Hi John, You hired us to clean your air ducts and then when we got to the job you were expecting us to remove a dead animal which is not something we are not in the business to do."

Outstanding service, easy to deal with. Service technician was a professional, efficient and thorough. Don't expect a service like this to happen quickly, set up time and cleaning is an art in itself. Dust Kings is definitely world-class in what it does best. They are not a "blow and go" service. I am totally satisfied and would highly recommend them for any duct cleaning project.

These guys quoted the lowest. Edwin came out and was super professional and was excited to proceed with him doing the work. Unfortunately when they came to do the work someone completely different than Edwin arrived. I don't know his name but his truck was a disaster and so was he. He was a mess. He clearly didn't know what he was doing, took way too long, and when finished the job was done incorrectly and not how it was quoted. It took forever for customer service to finally get back to me (over a week). Finally Edwin came and redid the work. Unfortunately he did do a couple things wrong but it's good enough.
Response from Insul-Kings

"We are sorry that you had a bad experience but are glad we had the opportunity to make it right. Edwin is a committed, long term employee (15 years) who takes pride and care to make his work perfect. Your review below states that he got a few things wrong and I would like to know what was incorrect. Edwin & Keith have tried following up with you by phone several times but have not heard back from you. Regarding Bret who initially did the work. Unfortunately Bret was experiencing health problems the day he did your job that resulted in a seizure. That is why he stepped away in the middle of the job. It likely affected his work. He has been with us for almost 10 years and we received very few complaints in that time. I want to mention he did all the duct work in my new home as well as complicated heating work so I know the quality of his work and his competence. We agree that his job at your home was subpar and redid it promptly. I have checked our call logs and we have returned your calls in a prompt, respectful manner and given the circumstances in a reasonable amount of time despite your exaggeration of a week. The delay was due to not being able to speak to Brett the next day because of his medical emergency. In response to your request for a refund to remove the review we find that unreasonable. You were delivered what you purchased. We regret that these things went wrong and fixed them with apogee. We guarantee our work and am glad that your dryer is not venting safely and properly. It is unfortunate that you choose to discuss your complaints over the internet with reviews instead of returning our follow up phone calls. I also wanted to add that you did cancel our first appointment without reasonable notice and we were accommodating, we ask that you consider all of these facts and reconsider your over crticials reviews."

Terrible time working with these guys. It was a nightmare of a time after the blew three holes in my walls and filled my living space with insulation. After a long fight they did a half a** job cleaning my house, only offered to dry clean my blankets and pillows after I complained several time. Took them about 2 months to get me my things back. I said I wanted a receipt from the dry cleaners to confirm they were not lying about how long it took the dry cleaners. They lied to me about telling mass save what happened. Mass save had no idea about them blowing my walls in. Mass save was under the impression they finished the job which they did not. They stopped half way through. I would not recommend these guys to anyone. Terrible company. I will leave reviews on every platform I can to prevent anyone else getting a headache from them. Better business bureau will hear more from me about this business.
Response from Insul-Kings

"We are sorry for the reviewers' dissatisfaction. The cellulose insulation (made from ground up newspaper) is installed from the exterior of the house through 3" holes we drill and fill, under pressure in order to meet insulation density standards set by building code. Cellulose insulation is safe but dusty and messy. Is the only type of insulation that MassSave pays for (100% free currently) and can result in wall cracking or blowouts, particularly if the drywall is thin as was the case here. MassSave did advise the customer that his walls could potentially crack & blow out and the customer signs off an acknowledgement of this. We did hire a local professional cleaning company to clean his home (from top to bottom) immediately, as seen in his pictures, and the walls were repaired promptly by a professional plaster. The bedding mentioned in the review was laundered by Anton Cleaners, again promptly, but did take a week to return. We, as well as ALL MassSave contractors deal with these types of situations regularly & have procedures in place to handle it. We have been installing insulation for MassSave for over a decade, with the same highly experienced, long term employees that performed the work on this house and have insulated thousands of homes in New England. We currently hold a top ranking with MassSave, (as well as with online ranking sites like Angie's List, Home Advisors). MassSave has said we did not do anything incorrectly on this job or in our response. We are required to report these incidents to MassSave who immediately dispatched an inspector who found no fault to us. The reviewer is obviously angry and has posted this same review all over the Internet but refuses to contact us back (emails, texts & calls) so that we can find out what further we can do to remedy any problems. These types of incidents are never welcomed by us or the customer. We certainly understand that this type of home improvement work is stressful for homeowners. Retrofitting the insulation in an old home is very intrusive & messy work. Most customers understand the inherent problems & risks and recognise our effort to avoid problems & in the rare case something happens that we correct problems promptly, In the rarest cases unfortunately some homeowners panic & freak out. We hope that when time passes and the sting of this unfortunate incident wears-off that the customer enjoys the added comfort and energy savings. We mean no hard or stress to the customer and hope we hear back from him soon to address his issues. UPDATE: After reading our reply he called us back yelling and swearing at our customer service rep who was trying to help him. This person has become abusive and unhinged over this throwing a complete tirate."

Removing old insulation and adding new can be a messy job but once the job was done the house looked great. They started and completed the job on time. Only glitch was on the initial day of the job, had to stop because some knob and tube wiring was found. This was old wiring not connected to a power supply but had to get an electrician to certify. I wish the estimator would have found that when the estimate was prepared. I was an easy fix, but required us to reschedule to another day.
