I would say, they did an excellent job - Starting with Jeremy, who accommodated my schedule for preliminary inspect and gave me a on the spot quote. Elder and the guys did an excellent job in covering up the entire house and finished the job in 2 days. My house had no insulation in the walls- to very less in the attic. After the insulation my Heat as well as Cold is retained inside the house. Heat turns on once in a 24 Hr cycle vs multiple times in an hour previously. If you are thinking of in wall insulation, it's totally worth it. The quote was the most competitive and they were very flexible. I am still closing out the multiple holes in the wall, will take time as i prefer to do it myself- I had plans to paint anyway .

I was initially impressed with what seemed like a thorough and well-considered estimate. It felt…read morelike the team really evaluated my attic and cooling needs. The addition of two QuietCool fans also seemed like a major plus, as I was already familiar with the product and expected it would significantly help with cooling. When it came to the insulation work, I was very pleased. The crew did an excellent job removing the old insulation and installing the new. They worked efficiently, protected my floors well, and ensured that no insulation debris entered the living areas. That part of the job was handled professionally. However, I was less impressed with the radiant barrier installation. This may partly be due to a misunderstanding on my end, as I expected a different type of material, but the end result did not meet my expectations. The biggest issue, unfortunately, was the installation of the fans. At best, it was very poorly executed. The fans are 16" units with 12" duct openings, yet they were installed directly against the gables, which severely restricts airflow. Proper installation should have included a box or shroud to help direct airflow effectively through the fans. Because of this poor airflow, the fans do not cool the attic--in fact, they appear to make things worse. I can actually watch the temperature on the thermostat increase when the fans are turned on. I reached out to my representative multiple times, but the response was disappointing. I was told they could not take the fans back, and when I asked why the attic temperature increases when they are running, I was told there was no explanation and nothing further could be done. As temperatures continue to rise, I'm left frustrated that I spent $1,200 on two fans that perform the opposite of what was promised, with no meaningful support or resolution offered. UPDATE: After posting my initial review, I was contacted by both the project manager and the owner. I reiterated the reasons for my frustration, explaining that my review reflected my honest impression of what I saw as a lack of clear communication and effective management of the project and customer expectations. The project manager apologized for the communication breakdown and asked if I would be open to giving them an opportunity to make things right. A technician was then sent out, and he took the time to fully understand the issue, carefully examine the installation, and make several adjustments to the original work. He believes these changes will help improve airflow in the attic. Since my attic has some unique characteristics, he also provided helpful suggestions for additional ways to improve cooling and airflow--something I feel should have been addressed during the initial planning stage of the project. Whether these changes will result in significant improvement remains to be seen; I'll have a better sense once the weather warms up. I do appreciate the follow-up and the willingness of the project manager to reach out and try to make things right, and I have updated my review accordingly. That said, I want to be clear that the increase in my rating is largely due to the technician and the time he invested in evaluating the full situation, as well as both implementing and proposing thoughtful solutions.

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.

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!

Not only did Attic King give me the best bid, they went way above and beyond to coordinate the work with me, as I live out of the area. The communication was always prompt, and all my questions were answered with the utmost professionalism and courtesy. On the first day the crew worked an extremely long day removing all the old insulation and ducting, completely cleaning and sanitizing the attic, and installing all new ducting. They sealed every entry point they could find where rodents were getting into the attic . Then they laid traps and waited several days to come back and make sure no more rodents were getting in before they blew in the new insulation. Throughout the entire job, their representative Ofek kept me informed of progress and included pictures at each stage of the job. In an era when Customer Service seems to be a dying art, it's nice to know there's a company that puts the customer first and backs it with excellent workmanship. I could not recommend them more highly!
