    Attic Insulation
    d h.

    This review is overdue as I got my insulation done back in June. Anyway, Miquan (the project manager) was very responsive and his bid was very competitive with the other bids I got. One of Johnson's benefit is that they are Bayren contractor and I was able to get a 1500 dollar rebate. Just to note, not all insulation contractors are Bayren approved. They insulated my attic and walls in under a day. There was a slight mishap during the installation but Miquan got on it immediately and resolved the issue same day. I'd totally recommend Johnson's Insulation!

    Competitive pricing, professional team and on time execution. I had both attic and crawl space insulation replaced, the team executed as planned. I highly recommend them.

    Johnson's did our attic insulation. The work is nicely done with R49 insulation bats. Oscar and his guy are the actual installer. They worked diligently for an entire day to remove all the old insulation, cleaned rodent waste, and sanitized the attics. They came at another day to put in new insulation which made a difference immediately. Miquan was very knowledgeable about the Bayren rebate program and he visited our house during the project to make sure everything goes well. They are very reliable and provide great customer service.

    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.

The space looked completely refreshed afterward! About a month later, I had them come back to add new insulation and handle the air sealing.

From the very beginning, the estimate process was smooth, clear, and professional. They took the time to explain my options and helped me choose the right Mitsubishi system for my home without any pressure. The installation itself was efficient and well-organized. The crew showed up on time, kept everything clean, and completed both the heat pump install and duct replacement with great attention to detail. You can tell they really know what they're doing. What really stood out was how seamless the whole process was--from the initial estimate all the way through permits and final inspection. Everything was handled properly, and I didn't have to stress about any part of it. Overall, a very professional and reliable team. I highly recommend Element Home Solutions if you're considering a heat pump or ductwork upgrade.

    This spring, our other furnace was shut off by PG&E for leaking carbon monoxide. I contacted…read moreElement to replace this and initially did not intend to get any other quotes. Ernest came and was again very thorough, but we did not use Element again due to: 1. Inflexibility about using our existing floor air intake. This is a large 3-ft opening in our living room floor, but Ernest wanted to make another large opening on the other side of the living room. Aesthetically this is terrible in a historic home and I pointed out that this would lower the value of my property. We had in-depth discussions about dimensions of ducts, locations of vents, etc., but ultimately Ernest was not able to commit to an alternative plan and I was not willing to sign a contract without knowing what the end result would be. 2. Pricing increased a lot for a similar job only about a year apart. Due to Issue 1, I sought out 2 additional quotes, which were about $10K less than Element ($32K). Both installers did not have any issues with keeping the air intake where it was. Had Element been only $5K higher than competitors and kept my air intake location, I would have gladly gone with them again, but 50% more is a big price difference.

There has been this persistent smell of rodent urine in one of our closets for literally decades, no matter what we have done. Not any more! I could not recommend Rywen Insulation more highly for rodent control work. We've had rodent control people here before, but never at the level that Rywen takes things to. They put in place genuine long-term preventative measures to keep rats and mice out, not just patching holes. And that has made all the difference. No more smell in our under-the-stairs closet! And, I'm not sure if it is always a part of their service, but they offered us a one-year warranty. Rats and mice did return --- probably due to a contractor leaving our crawlspace door open overnight with the lights on, several times (oops). But Rywen took care of the problem immediately, no questions asked and no additional money requested, for the entire year of the warranty. They aren't cheap. But they are soooo worth it.

    I called this company after two others flaked out on us. Gabriel, the owner, came out to do the…read moreinspection himself, and gave me tons of information about the differences and the pros and cons of each type insulation, and giving us a quote on the spot. We initially agreed to have both the attic and the crawl space insulated. When I told Gabriel that the kitchen fan is currently venting into the attic, and that we need to find a roofer to make a hole to vent it outside, he offered to connect the fan to an existing fan, at no charge. We later changed our minds about the attic and decided to just have the crawl space insulated for the time being. But Gabriel insisted on fixing the kitchen vent anyway, even though his men no longer needed to climb in the attic at all. I protested, but he said he'd agreed to do it, so he will, still at no cost. I was flabbergasted by his generosity. The three young men who work for him were all sweet, polite, and arrived early, and left the place spotless, both inside and out. (As opposed to another company whose inspector left muddy footprints all over the beige carpet, even after I laid down some newspapers.) I can't recommend Gabriel and his company enough. He treats his customers as if we were family. Oh, and there's ALWAYS a nice secretary, Jesiemae, who answers the phone and books you an appointment on the spot. No annoying voicemail tags. Thank you, Gabriel and your staff, for letting us start the new year in a warmer house!

    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.

The estimator's in-person presentation was very good -- professional, clear, and well organized. The overall process was explained pretty well however I needed more info after he left. The one key issue for me was the R-rating and since R-value is a major factor in comparing insulation options, I wanted to understand exactly what was being installed. I tried to follow up with the estimator to get clarification and asked for a call back. While multiple emails were exchanged from what seemed to be the corporate end, there was no actual human interaction, and my request for the estimator to call back failed. Because of that lack of follow-through, I ultimately decided to go with another vendor who was more responsive. AttiCare made a good first impression, but communication after the initial visit failed. I wouldn't proceed without speaking to the estimator. They lost a job due to that.
