If I could leave a worse review I would. I will make sure to leave the lowest review I can on each platform I can find. These guys were terrible to work with. My experience with them stared off fine until the blew through 3 sections of dry wall in my house. They took forever to replace the drywall, did not clean my house, and they were hired through mass save. They did not finish the job insulating my house. Then proceeded to tell me that they told mass save about what happened, and I called to confirm with mass save and they had no idea about what happened. They offered to dry clean my pillows and blankets after I complained several times. They took them and took about a month and a half to return them and blamed it on the dry cleaners. I told the guy I wanted a receipt to confirm with the dry cleaners that they took that long. They did not give me a receipt from the dry cleaners. These guys are shady and unprofessional. I will continue to let everyone I know that these guys suck. I will make sure to leave reviews on every platform in hopes no one hires them for work. Hopefully a call to the better business bureau can help change this business.

During the installation there was an accident in which multiple feet of insulation were blown into a bedroom and dust and debris blew throughout the rest of the house. The crew on-site were apologetic and did their best to clean up right after the accident. but Bobby and Carlos were unapologetic, unresponsive, dismissive, and rude. It is completely normal for blown insulation to occasionally crack a wall in an older home (which happened earlier in this job and was noticed in a timely fashion and cleaned appropriately), but this was not a run-of-the-mill accident. There was so much insulation that they used snow shovels to scoop it into garbage bags, and the insulation not only blew into the room but also into the closed closet and dresser drawers. It traveled into the other bedrooms and downstairs. We could not stay in the house because of the extent of the mess. I tried repeatedly to contact Bobby without response on the day of the accident and also the following morning. When I finally heard back from him he was dismissive; he wouldn't come see the damage until later in that day because he had an appointment with other homeowners whose problems (in his words) were just as important as mine, and that it would be multiple days before clean up could begin. I ended up having to contact my insurance company, who immediately sent people out to inspect and clean. Despite repeated calls from both me and my insurance company, it took around two weeks to get Insul-Kings' insurance information. Because of this, my insurance company covered most of the expenses and I paid over $4,000 of out-of-pocket in order to clean up. The situation got so bad that I had to consult a lawyer and Insul-Kings threatened to put a lien on my home because I wouldn't sign a Certificate of Completion saying that the job was done, even though I was still out thousands of dollars and the damage hadn't been repaired. In the end, the cleaning and repairs cost over $15,000 and it took over six months before the situation was finally resolved through our insurance companies, and both my insurance company and I were reimbursed. I was actually very understanding upon learning of the accident, as it was just that ? clearly they did not intend to blow a layer of insulation a meter deep into my house. That said, I was appalled at the treatment I received from the management as I tried to resolve the situation. Had they acted swiftly and with professionalism, cleaning up the error and returning the house to a habitable condition in a timely manner, I would probably be here praising them for their customer service. Instead, I cannot recommend them at all.

Response from Insul-Kings
This review is a great exaggeration of what happened. The customer completely over reacted after cellulose insulation which was being blown in from the exterior of the home entered through a hidden cavity that lead to a closet. We performed an initial cleanup that evening with arrangements with the homeowner to return the following day to complete & take necessary action to clean the job to the customers satisfaction, (this happen in the last hours of a multiple day job, on a Friday night). After we left that evening the homeowner calling in Service Masters who specialize in emergency fires & floods cleanup for whom were more than happy to charge her through the roof to clean her apartment on a Friday evening and Saturday morning. Instead of cleaning cloths that were exposed to cellulose insulation (ground newspaper) Service Masters sent it out for "restorative cleaning" costing thousands. So effectively the reviewer was taken to the cleaners by Service Masters who were only interested in blowing up the cost for an insurance claim (have you heard about the $55k tow bill sent to an insurance company on the news recently). Unfortunately there is the possibility of cellulose & cellulose dust entering a home when insulation wall from the outside. We have had other customers overreact in the past to this (taking there children to the emergency room because they were exposed to cellulose). We have had many cases as have every company that retro-fits insulation into home of insulation entering a home through some hidden opening (usually not caught until there is a sizable amount of insulation in the cavity / closet / room) all handled by a simple cleaning weather done by a home cleaning company or the insulation company themselves. All parties (Mass Save, National Grid, & Insurance Companies) all agree that this was a complete overreaction and that the customer has gone out of her way making a mountain out of a mole hill. The customer never paid a cent for the insulation work we did for her owing us her portion. Mass Save did pay us for the job despite the homeowners refusal to sign that the job was completed because after there inspection they found the work to completed completely and correctly.

Great quality of work and easy guys to work with. Some lack of communication between estimator and installers led to repeat visit because of the custom nature of the work capping my attic stairs (thus the overall B instead of A). Resolved quickly with a few calls back and forth and job got done.

I replied back saying I would still like to get an estimate. That was over two weeks ago. Never heard back from the company. Based on my experience, I cannot recommend this company.
Description of Work: Emailed Insul King for a quote to install blown insulation in an attic space. It took two (2) weeks to get a reply that stated " I was cleaning up our inboxes here and saw your email from two weeks ago. It looks as if no one replied". The contact person at the company then left a phone number to contact (which I did, and left a message) and also replied to the email - which he said he would get (i.e. reply would go directly to him).

We tried reaching this member by phone several times over 2 weeks.. We then attempted to email after failing to reach him by phone. The comment was related to finding the member's original email & address. We are sorry that the member was dissatisfied and hope he was able to find a contractor to meet his needs. We feel the grade is a bit extreme but can assure the reader that we have a fully staffed office with 3 people handling phones, a call center that take calls overnight, and make every effort to contact potential customers.

The customer was upset that we recommended that no one should be home while we spray foam insulation & a period after while the house airs out. We are not sure how this wasn't explained to her, (by us or any of the other contractors whom she met with) and are terribly sorry for the inconvenience it posed on her and her family. Naturally retrofitting any insulation in a home that is being lived in, (regardless of type of insulation material) provide some level of occupancy issue during and after installation. When our (non-commission) certified Energy Auditors meet a prospective customer for a free estimate, we try to be as comprehensive as possible and review an extensive packet of sales literature that is left behind. We are sorry if there was a failure of delivering appropriate information but naturally this would have been an issue regardless of whom the customer hired; therefore I feel that the reviewer in being extremely harsh and unfair in her brief but punishing review and in how we were treated after being hired. It would only be reasonable for the customer to have also done her due diligence, especially being a doctor. After the occupancy issue came up we were told that that the job be completed on a Saturday or she would cancel the job. I would consider that we were fairly courteous given that we are a M-F operation that doesn’t schedule work on Saturdays, therefore requiring us to essentially bend over backwards to do so, incurring extra expenses & overtime which were not passed on to the customer. The homeowner wasn’t home when our crew arrived; they were let in by a neighbor who locked up after the job was completed, never meeting our crew to at minimum review the job scope before they started. This customer is in collections as she shorted her final payment to us by $208 with a note explaining her rational for shorting us. I wonder how acceptant she would be of one of her patients shorted a payment to her with a note stating that they feel that they should arbitrarily reduce the payment to a number they feel is reasonable (maybe she is thinks this is Obama Care). We have addressed her every complaint, and have followed up responsively (requiring days of messages before we get a returned call from the start). Communication has been an issue as we feel she just lashes at us since this occupancy issue changed her outcome, intentionally making things difficult to complete the job and now to receive payment. We have a detailed, written contract with this customer, and I feel the retribution from this unreasonable customer is unfair to say the least.

Workers were very punctual, polite, and helpful; they cleaned up very well, and the next door neighbor commented on how well they removed all the debris from the job. Consulted with me on a problematic area to agree on a solution. Went out of their way to do a great job. Their price was a bit higher than others quoted, but I feel it was justified by the thorough job they did.

Thank you for the kind feedback. We strive on bringing the highest level of service and quality to our customers as we hope to be given the opportunity to serve your friends and family. I would like to respectfully note that we do not set the pricing from Mass Save which is who facilitated this job. The work is subcontracted to us at set prices (of which we do not favor - they have very high admin costs). We hope to have the opportunity to serve you the reader and prospective customer. Best regards.

On 1/16/13 sent email requesting quote. They responded quickly saying they'd be in the area on 1/18/13 and made the appointment. Jim, the estimator, called saying he'd be a little late and arrived within the time he said. He was very professional and thorough in his estimating. He said I should receive the estimate in a couple of day. On 1/22/13 I sent an email asking when I could expect an estimate. The next day I received an email with an attached PDF file. The next day I sent this email: and quot;Two things about this estimate: 1. There is no total. The main reason I'm asking about this is there is a line item and quot;Note! Dam around hatchand quot; with no price. So is that included in the total price or should there be a price associated with that. Also, what is placed over the hatch? Is that included in the price? 2. I know my current insulation has R30 listed on the batts. However, it is current about 7and quot;. Based on my research that would suggest the current R value is about 21. Therefore, I'd like to have 8and quot; added. Of course, if I'm incorrect or misguided your guidance would be appreciated.and quot; I never heard back from them. Update 5/22/13 The company says that they cannot find my email and that maybe I used an email account that they don't monitor. I used the email address info@negutterkings.com. This is the same address that I had used 2 previous times and they responded to both those messages. However, to their credit once they saw my review they tried to contact me. Since I had already picked another company I didn't respond to their followup.

We apologize for this customers frustration. Jim the estimator is attempting to reach this member. The member states that he replied to Jim with some questions and he did not get a reply, we have no record of his followup but can only guess that he replied back to the email address used by the copy machine from which we hand send written estimates and not Jim's direct email address. We do monitor this email box but again have no record of it. I can tell you that every estimate is important as is every customer and we work hard to earn every job and would never intentionally blow off a potential customer. We hope to still have the chance to earn this members business.

The preliminary Combustion test was great. The safety benefit alone, just what I learned from Cliff, was worth while. The house was venting properly. No concerns with CO2, etc. Very cool process. When the three man crew arrived to Air Seal they did not stop from start to finish. Very prompt, very professional and they shared a lot of valuable information about what they saw. The second Combustion Test showed a GREAT result. Near perfect by the standards for my home.
Description of Work: I first had a Combustion Test of the House. A few days later, the full crew arrived to Air Seal the attic and under the sinks in my home and do the Combustion Test a second time to see the result of their work.

I went through the MassSave program to have my insulation redone. I have an older house and my heating bills were far too high. The work was specked out and another insulation company came to do the work. When they got to my house and began, they told me that if they do only the work that has been contracted, my house will be only partially insulated. I told them to leave and that I would call the MassSAve people to have this fixed. Updates were made to the work order and I needed to get another date scheduled for my insulation work to be done. When I called the original company, they said they couldn't get to me until end of December. So I looked on Angies List (and the list that MassSAve gave me), and picked Insul-Kings. They could get to me in less than 2 weeks. The guys came when scheduled to (although they showed up an hour early and I wasn't ready for them) and work hard all day to get all the work done. They were a super nice group of guys. They accidentaly knocked my front off its alignment and it wouldn't shut all the way. They stood out in the rain for a good 20 mins fixing it. It shuts better now than it ever did. My house is super toasty now. The insulation is doing the job nicely. And when MassSAve came back to inspect the work they did, the inspector kept saying what a great and thorough job they did.

Bobby DeSousa is the best. He returned every phone call and email promptly and took time to explain every step of the way. He accommodated our schedule (we were in a big rush to have enough time to get the house painted right afterwards). His crew were all polite and cleaned well after the work was done. And when he found out that that a small section in the walkway to the attic already had insulation, he took that cost right out of the price. I would definitely use him again. I did not specify the price because we went through MassSave program so the overall cost was determined by the evaluator, not the contractor who does the job.

The experience was excellent from start to finish. Bobby DeSouza was very knowledgeable, friendly, and was good at communicating with me. He always kept me in the loop. Insulkings was very customer-oriented and prompt in responding to any questions or concerns that I had. It was a real pleasure working with them. The insulation of our attic went very smoothly aside from a crack in the plaster ceiling. When I told Bobby about it he was quick to respond and took care of it right away without any cost to me. The plasterer that he had hired did a nice job and the crack is not visible. I will definitely hire them again.

A date was never set with this customer, and this is a big misunderstanding. We contacted this customer to schedule the job and the customer told us that he was only available on 1 particular date and assumed that we were coming that date. When he called that morning the person who answered assumed he was talking to the customer who was scheduled that day as it was the only insulation job on the schedule. We are sorry for the inconvenience and would NEVER EVER intentionally blow off a customer. We take customer service seriously, and people time respectfully and take pride in being punctual. We have 4 full time customer service people in our office 60 hours a week and a night call service for after hours and weekends. Our customer service manager is on call 24hrs. We work hard to communicate to our customers and when the customer wasn't available for the opening we were trying to fill he somehow believed he was scheduled the date he was available. We are glad they were satisfied with the replacement contractor and hope they enjoy the added comfort of their insulated home.

We did a program through the state for energy savings, so it was discounted heavily. I recommended them to my parents because I liked the work they did for me in the past. They did a good job, they were on time, the guys were neat, they cleaned up after themselves, and they did what they said they would do. It was good work for a reasonable price. I thought it was good that I actually talked to the owner of the company.

Dealing with this company was a great experience. They send a certified home energy audit to meet with me and look at my home. He gave me several options and reviewed each in detail. We had this done before Thanksgiving and have noticed a significant improvement in the comfort of our home and the difference in our heating bill. It was very interesting watching them perform their tests with the variety of equipment (the IR camera was the coolest!). The guys who performed the work were very polite and thorough. They did a great job cleaning up and were courteous to our family over the 2 days they were at our home (I had no idea how much work it would be) but they handled the entire process professionally. I have passed their business card to friends and highly recommend them to all of you.
