"Excellent communication. Delivered on time with quality install."

"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!!!"

"We had Everguard Home Insulation install Applegate cellulose insulation in our attic on 2/2/18. They did an outstanding job! Everguard was very professional and competitively priced. (We had four estimates. They were not the cheapest but their reviews were outstanding. They have had their license since 1964 which says a lot.) They arrived on time and the insulation was quick and clean. They moved furniture and cleaned up thoroughly. We highly recommend Everguard if you need attic insulation. Since the insulation, we have not had the temperature swings we had in the past. In fact, we have not had to run the heater in the early morning since the insulation was installed."

"Very smooth process. Amir scheduled the site visit the week before and then followed up with a clear description of what could be built and what couldn’t be built on the property. Would definitely use again!"

"Very pleased with the quick installation after the quote from Benji. Courteous, professional installation by Lance and Riley."

"Joseph and his team were all so helpful and educated. My home was very hot upstairs even with the AC on. After E&E Insulation finished attic cleaning and installing R38 insulation I feel such a big difference in the temperature. The temperature stays the same throughout the whole home. I don’t have to have my AC blasting all day anymore. They saved me so much money on my energy bills. Thank you for everything!"

"Everyone was fantastic from Sales rep to installers!"

"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."

"Bill Selinski and his crew transformed our house. Every phase of the extensive work was performed with care. The carpenter did an expert job on all the wood work and installation of a window and frame. The overall look of the house- the color, finished surfaces, and siding--is great. Bill was interested in meeting our requests and more, supervised every phase of the work, and informed us of what was being done each day. I highly recommend them."

"I highly recommend them. Glen (& Patrick) were professional, did excellent work and the job was finished in a couple of days as was stated to me at the beginning. Very easy to work with! I would hire them again in a flash!"
