    I asked for a rough estimate online without an inspection for a typical 1100 square foot house…read more They told me it it was illegal for them to give a rough estimate without an in person inspection because they are licensed. A few of the places I checked with didn't want to give a rough estimate, but none of the them lied about their reasoning, so they didn't get reviews. Some even gave me a rough estimate right here on yelp. Based on some of the other reviews, it seems like this sort of pressured sales approach is their business model, instead of helpful answers and good work.

    This was the lowest bidder by maybe 10% and did OK work, but I had to check their work then request…read morecorrections, and they were unclear on scope options so I was left with unsealed fixtures and fiberglass debris in the house to clean up myself. While they did work with me, did exceed expectations in rodent proofing patch support, and were quite friendly and ready to correct most shortcomings I pointed out, I would have preferred they not rely on my oversight to give quality work consistent with my original direction. They did not tape off a sealed plastic tunnel from the front door to the attic, did not let me know sealing off light fixtures was excluded, left some spotty gaps between batts of insulation and between batts and joists and did not run a second layer of insulation where I had requested it perpendicular to the first layer to better air seal joist gaps. They were unclear about IC-rated lights in contact with fiberglass batting insulation and its fire risk and did not seem to know the code on attic ventilation requirements enough to answer questions fans or vent sufficiency. Granted, I did not have insulation removal as part of the scope, it was already done by a prior contractor during rodent proofing. Instead of making a tunnel, they taped off a small space from the attic hatch to the floor and put construction paper down on the floor. This helped with scuffs to the floor and may have contained some of the fiberglass dust/particles, but did not protect from scuffs on the wall or contain the fiberglass during transit to the door that was shed from the new batts being carried in or from their clothes and shoes, even though they generally had only one person trafficking the batts up to the hatch. They bagged up debris in the attic and carried batts in bags in from the door. They removed all the paper and plastic before I was done with my inspection, an inspection that yielded more work required, then they didn't put protection back for the short time of rework. The foot traffic left some fiberglass flakes and particles strewn about the floor. It took me two hours of cleanup to get that debris fully clean so my baby could crawl on the floor again. I vacuumed with a shop vac, made three passes with a swifter dry duster, and vacuumed with a house vac. I suggest asking them during the bid stage about the following, getting a quote for that work (with optional line items if you don't need everything), and confirming it is written in the proposal/bid/work order scope before awarding the project: - a sealed tunnel for transport of removal and installation - cleanup with vacuums and swiffer after until no particles remain in house on floors or touch surfaces - air-sealing fixtures and other gaps from rooms below - code and safety insulation contact with fixtures and blocking with gaps (2"-3"?) to avoid contact - insulation contact with rafters/roof battens/sheathing - roof ventilation adequacy and fan install if needed - gap prevention - running a second layer of batts perpendicular to the base layer for better air sealing - minor or major rodent proofing gap sealing with mesh and foam This is a good list to consider for any contractor you use, some contractors may find this obvious or already include it, but you could still benefit from knowing what to check for and avoiding change orders. I ultimately was satisfied by the work and they made some corrections and concessions to balance the expectations vs delivered result, but would have been happier with more clarity of scope options (too late to seal the fixtures now unless I pay $600 more or do it myself) and I had to do lots of cleanup that I could have avoided if I simply rejected their suggested home debits containment method of bagging with no tunnel. Although I would not suggest this crew if you are not prepared to check their work, which not everyone is physically capable of doing in tight spaces of some attics.

    Having used Everguard previously, they were my first choice for another insulation project. Jose…read moreand his crew arrived and immediately set to work prepping the access areas to ensure no debris would be left behind. They worked well as a crew and finished the job within the time that was estimated. The results are that we can depend on a more stable temperature in the house with much slower temperature swings when off the HVAC. When using HVAC, it works less to keep the temps where we set them. I'm constantly bragging about our blown-in insulation by Everguard.

    The company has been in business for 67 years!! That in of itself speaks volumes. Their end product…read moreis absolutely professional, and for a good value. Their installers are delightful, helpful, and team players. A second pair of eyes are necessary during installation. Getting to the end product can feel like pulling teeth. extremely belabored. Administratively much needs to be improved. The right hand doesn't know what the left hand is doing. In my case, I had to have several repeat site visits because what I communicated did not end up on the Estimate multiple times, so on the third time I actually needed to write down every item step-by-step to hold them accountable for the bottom line, which still needed to be tweaked in the end!! That being said, I will say the team is honest!! It was discovered during install that a large portion of my job was already insulated and could not be blown-in. My estimate was changed on-site and I was billed only for what I used. EXCELLENT business acumen. That's what 67 years in business will do. I absolutely will not hesitate to recommend them, however, I will advise caution with the sales steps of this business. perhaps it's best to request everything you want in writing down to the specifics, including square footages, that way there can be no misconception of the scope of work...

    Marathon Insulation is the real deal! They check every box: knowledgeable, caring, honest,…read morecommitted, trustworthy, communicative, and accountable to their work. You can tell that they pride themselves in the work they do and go above and beyond. Jonathan, Ralph, and his crew were phenomenal from start to finish and made sure they took care of all things related to their work. On top of this, their pricing is super competitive! It's hard to find an ethical and caring company like them nowadays but I'm so glad I found them. If you're looking for insulation needs, look no further - seriously. Thank you Marathon Insulation!

Their pricing is unbeatable, their work is fast and clean, and they are extremely responsible, friendly, polite, and respectful. They treated me like family from the moment they arrived. Not only did they finish my house perfectly, but even my neighbor saw their work and immediately asked about it. Since Jonathan and Ralph already had their equipment on-site, they offered him an amazing price too and got his house done the same day--two houses in one shot! Their professionalism and quality of work are on a completely different level. I 100% recommend this company to anyone looking for insulation. These guys are winners, and they truly deserve all the support and success. Thank you Jonathan and Ralph--if you ever need anything from me, even a glass of water, just ask. You guys earned it!
