"Insulation labs is the company most customer focussed I have had in my 83 years. Very responsible,friendly and eager to address successfully any confusion and/ or misunderstanding in the execution of a job contract. I will always use Insulation labs for any work they perform. I want to commend the Insulation labs chairman, Angel, for his integrity, commitment to serve the customer, friendliness, and honesty. I wished we had people like in other business and politics. I would be a much better country."

"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"Great service from a great company! Jonathan and his team are professional, skilled, efficient, and reliable! Came by for a free check of current insulation (there was none!!) and arrived 15 minutes earlier than his scheduled start time! Our house is built in the early 50s with no insulation and old walls, but him and his team worked quickly and efficiently, and the difference was HUGE! Before these guys, the AC ran about 19-22 hours a day (my Nest tracks this stuff) to try to keep temperature at 74 and it almost never actually reached it till maybe 3am, then was off for an hour, then on again. During the day, house temperature would go up instead of down despite the AC's best efforts! Don't even get me started on the 500+ electric bill for a 1200 Sqft home! Now, a day after their full wall insulation from the outside (no damage to interior AT ALL), the house stayed at 73 even though the AC was powered off from 4:30pm until now, 10:20pm, and was even off most of the time before that, only coming on for a few minutes every few hours to bring it down 1 degree, the way it's supposed to work. Outside it was 90s with hot gusts of wind. I could not be happier with their work, level of expertise and professionalism, friendly demeanor, and GREAT pricing!! Masterful job, Marathon Insulation. Will definitely refer you to all my friends and family, well done and thank you for coming thru before the heat got even worse!! Props Jonathan and crew, wish you all the best."

"This company had the best customer rating of all the ones for blown-in insulation and I can see why. They responded to my request the next day and gave me a straight price per sq ft with no extras or up selling. Made an appointment right then. The guys showed up on time and were done in about an hour, very clean and efficient and there was no mess or cleanup whatsoever. We noticed the difference right away as my A/C did not have to run all day as soon as the insulation was installed. Highly recommended."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"Their entire staff, from the estimator to the installer to their back room were all professional. I had them insulate the entire house. I would recommend them."

"I hired Elm Installation Services for window replacement and had a good experience. First off, they answer the phone! Second, they get your materials ordered right away so that you are out waiting around for the no. To be done. Third, it is reasonably priced for the quality you are getting. Lastly, they are true to their word with being on time for the appointment and making it as convenient as possible. I work from home so it is very distracting to have workers hanging around. Not these guys! They were in and out and did not leave a mess. The workers were friendly and professional. Moreover, Eli is trustworthy and he gained my trust pretty much right away, which says a lot because I am a lawyer. Once I saw how professional he was I was able to relax because I knew I was being treated with respect and integrity and that he was not going to cheat me out of my money. I would recommended him to a friend or family and believe this is going to help with an on-going neighbor issue so I can sleep!"

"The work was completed sooner than promised. I am very satisfied with this company and the work that they completed. They gave me a 50 year warranty for my shingle roof and replaced all the insulation in my attic. Thank you atom builders."

"Excellent and clear communication by David from bid to job completion. Had stucco walls insulated, which included drilling two holes per stud cavity, filling with fiber insulation, plugging holes with styrofoam, patching stucco, and finally painting to match the existing house color. Paint work went above and beyond to ensure that the new paint blended properly into the existing house. Most other insulation companies won't bother with the fine details like paint - it's really nice to have it all done by one person for nearly the same as just the insulation done by someone else."
