They might be on time and clean up after they are finished but it's best to climb under and see what was really done I wonder how many satisfied clients have done that. They did insulation under our house for over$4000. Before they did their work the heating ducts that had been covered with fiberglass batt and a heavy vapor barrier but Sergio, their estimator, said we could do better. After their job these aluminium ducts were left exposed and lost all their heat before reaching the farthest vents- blowing ice cold air into the house. Our bills have skyrocketed. A heating repair service says that's not code. And where is our permit? Was it inspected? Looks like the permit didn't happen. Mr Kennedy said in the spring he'd have workers come out and cover those ducts. Haven't heard from him since. Looks like our only option is trying to go to court. But first we'd have to find him.

Mr. Insulation's current owner, Nathan Price is dishonest, incompetent, and untrustworthy. The…read moreprior owner, Charles Bennet, was awesome. But Price - whose contractor's license has been suspended (as of April 2026) for about four months - is a nightmare you should not invite into your life. He was brought in to do the insulation work on a single family home and did not complete it for 15 months. He lied about having a work crew available and made numerous (generally false) excuses for his chronic absenteeism. The delays cost a great deal of money. After 15 months of no-showing on a daily basis he claimed his schedule was booked for the next year and he would come to finish the job when his schedule allowed. He then falsified my signature on an estimate and filed a fraudulent lawsuit based on a forged contract. He does not keep time or materials records and dramatically inflates his invoices. HE DOES NOT PROVIDE WORKER'S COMP FOR HIS EMPLOYEES AND THIS IS WHY HIS LICENSE WAS SUSPENDED. If you like being subjected to fraudulent bills, forged signatures, endless delays, and post-construction litigation, then hire Nathan Price. Otherwise, steer clear.

ROCK STAR!!! I love everything about Mr. Insulation. First…read morethe owner, Nathan, is extremely knowledgeable about insulation; the various selections, the good, the bad and the ugly. He gives talks on insulation and is considered an industry leader (see photo). Second, he is extremely conscientious. We discovered I have fiberglass sensitivity and could not even enter our house during the removal process. He took the issue seriously and really took extra care to ensure the attic was free of fiberglass. Other contractors remarked that the attic looked as clean as a newly built attic! Finally, our project included more than the attic space and required that we go into every wall cavity, crevice, nook and cranny. We found rodent nests in old fiberglass which was alarming to me and so we needed to have all insulation removed and all infiltration holes found and closed! Nathan was completely nonplussed, cool and composed. I feel so much safer in my home now. I know the air is good. I know our insulation choice is a healthy one and I know we are pest free. The man took care of us in every way possible! I cannot recommend him highly enough!

Everyone was extremely experienced and the work was completed on my home quickly and efficiently, with everything having protective plastic sheeting all the way from my front door to the work areas. The sales rep that came out to do the initial inspection and to give a quote, was very experienced and answered all my questions. We agreed on a course of action, and I later discovered I needed additional work, and he worked with me on getting that added. The workers arrived even earlier than expected on the day they were working on our house. They clearly had all the appropriate material and machines and equipment to do the job correctly. I feel very good about everything that was done and I would definitely recommend them. Everything was left clean and there was nothing I had to do to clean up behind them. The reason I am not giving five stars (only 4 stars) is because of the paperwork having multiple errors, and they took weeks to get me the pictures of the before and after shots of the work they did. I asked them to correct some errors I found in the paperwork, and even found more errors and had to ask them a second time to correct the invoice for my records. I also questioned whether the correct insulation was put into a certain wall, because the paperwork was incorrect. It took a physical callback from a different person to physically check, and he didn't really seem to understand clearly what the problem was. I showed him pictures of the insulation rating that I took for that wall, and he was about ready to go and purchase the insulation and redo the specific wall I was questioning. But then he just called the installers and they told him they put the correct R-Rating on that wall and then he left. He clearly was not trained well enough, and I still don't know if the correct insulation was put on that wall. All the hassle of the paperwork correction and reinspection of the work was not necessary if they paid attention to details better. But other than the paperwork and questioning a specific wall, the actual work was professionally done and these guys clearly are a good professional organization. Just keep an eye on the paperwork and go over all the lines of work in the contract before you sign it. Don't rush and sign what they give you. Read every line on the contract to look for errors. As far as the value for the service and work, they were right in the price range I was expecting. Don't hesitate to use them.

They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home.

Beyond easy experience with Chris. My dryer suddenly started giving off a burning smell, which I…read moremistakenly attributed to the lint catch being overloaded. But even after cleaning it out, the smell wasn't going away. Then the vent started giving off either smoke or steam, and in a panic I immediately turned off the dryer. Thank God I didn't start a dryer fire. The second I shut it off and made sure everything was ok, I opened Yelp and searched for a dryer vent cleaner. Chris's Insulation came up, he had great ratings, he was super close by, so after calling a different service and going to voicemail, I called Chris. Chris picked up after the second ring. When I told him that I needed someone to clean our dryer vent and what had happened, he said he could come out either between 5:00 and 6:00 pm that evening or the next day. It was already mid-afternoon when I called, so I was surprised to hear him say he could still come out same-day, but I decided to have him do that since I was free and also still a little shaky following what happened with the vent either smoking or steaming. Chris showed up during the window he quoted and wasted no time getting to work. He started the second he arrived and was done within the hour. His pricing was incredibly reasonable and fair and so far, in the couple of weeks since he was here, we've had no issues with the dryer. Before he left, he also sent us a ton of pictures of what the vent looked like post-cleaning. Super happy and relieved.

We first called Attic Kings about 4 years ago after heavy rains led to rats getting into our attic…read more They caused a huge mess, and I was especially concerned about the urine, droppings, old insulation, and fiberglass getting into the rest of the house. Moshe came out right away, inspected everything, and gave us a very reasonable quote to seal all of the entry points, clean and sanitize the attic, deodorize the space, remove all of the old insulation, and eventually replace it with new insulation. One of the biggest concerns for me was cleanliness. We had just installed brand new carpet upstairs, and the attic entrance is right there. Moshe covered everything in plastic and actually created a contained tunnel from the attic all the way downstairs and out the door so the old insulation and debris never traveled through the house. That made me feel much more comfortable about having the work done. Moshe and his team were fast, clean, and efficient, but what I appreciated most was how thorough Moshe was. He took the time to explain everything, sent us detailed photos, and never made us feel rushed. Because we have two attic spaces that connect along the roofline, Moshe did not just seal everything and immediately put down new insulation. He left traps in place and came back for several weeks to make sure there were no rats still hiding somewhere or finding another way in. Only after we were all comfortable that the problem was completely resolved did he install the new insulation. I really appreciated that because the last thing I wanted was to spend money on new insulation and have it ruined again. 4 years later, we still have the trap up there and have not had another rat problem. Recently, we had a completely separate issue with yellow jackets that made an opening near the roofline and got inside the roof area. After pest control handled the yellow jackets, I called Moshe just to ask whether the opening needed some kind of special repair. He came out the very next morning, walked the perimeter of both rooflines, found a few small areas that had shifted or opened over the years, sealed the area where the yellow jackets got in, and even went back into the attic to make sure everything was still secure and there was no evidence of rats. There wasn't. What really impressed me is that this was years after the original work, and he still came out as a courtesy to check everything. That says a lot about the kind of person he is and how he runs his business. Another thing I really appreciate is that when you call Attic Kings, you actually get Moshe. You are not dealing with an automated system, a call center, or a different person every time. He is very hands-on, and the people he brings with him have always been professional, respectful and clean. We even scheduled the original work while we were away from the house, and I felt completely comfortable trusting Moshe and his team in our home. His pricing was competitive, the value was excellent, and most importantly, the work has held up for 4 years. It is getting harder to find small businesses where the owner still answers the phone, shows up personally, stands behind the work, and cares about maintaining a relationship with customers long after the job is finished. Moshe is honest, dependable, and has a lot of integrity, and that goes a long way with me. I would absolutely recommend Attic Kings.

We found Attic Kings through Yelp, and had a really great experience! Ofek and Moshe were…read moreresponsive from the start, which made the decision easy after their consultation. A few days after we met and I signed the contract, the team came out to remove old roof debris left over from a recent reroofing, removed our home's original insulation, and installed fresh batt insulation in both the attic and crawlspace. They also added rodent proofing throughout the attic while they were at it. About a month later we heard critter noises, so I texted them and they came out to inspect. He didn't find anything in the traps but reset them to be safe. Sure enough, something took the bait because we heard it go off! Jose came back shortly after and discovered 2 mice (thankfully no rats), found a gap where the roof met the garage and sealed it up. He ran an ozone generator as a precaution for any smells. A couple weeks after that we heard faint sounds again. Jose returned, found one more entry point, sealed it, and since then there's been total silence! I really appreciated how thorough and persistent they were even after the job was technically done. Solid team, fair price, and they stand behind their work. Highly recommend Attic Kings!

We had an excellent experience working with Eduardo and his team…read more From the start, Eduardo was incredibly responsive, helpful, and easy to communicate with. We had a pretty large job that included cleaning, rodent-proofing, sanitizing, and re-insulating our attic, as well as cleaning, rodent-proofing, sanitizing, re-running our ducting, and laying plastic in our crawlspace. It was a big project that took about a week, and they showed up on time every single day, checked in regularly, and worked hard throughout. Along the way, we discovered a pipe leak, which they fixed without issue. We also needed to reroute our dryer vent, and they handled that as well. Even with these unexpected additions, Eduardo stuck to his original quote, which we really appreciated. The quality of the work is excellent, and we are very happy with the results. On top of that, Eduardo is coming back in two weeks to make sure the rodent-proofing is fully effective. That level of follow-up and accountability really shows he stands behind his work. Overall, Eduardo went above and beyond. Fair pricing, high-quality work, a professional team, and great communication. We would absolutely recommend him.
