    Sealing air leaks

    Ruben was a pleasure to work with at Greenstar Attic. We contacted several companies to evaluate our attic insulation and during the consultation with Greenstar, Ruben was knowledgeable, honest, communicated well and quickly through messages and over the phone, and provided numerous options to fit our budget. Since our original insulation was in good shape, we decided, based on Ruben's recommendation, to add more blown-in insulation to our existing insulation and use Greenstar as our contractor. During the day of installation, Ruben provided us a heads up and showed up promptly at the time we scheduled. Ruben and his team took their time to prep our home, ensuring that any space they needed to work in was fully covered with protective plastic. Ruben was thorough in completing the job, taking photos of the process and communicating with us through the time he and his team were working in our home. Ruben took time to show me the job he had done in the attic, and then his team carefully cleaned up after the project was completed. Ruben finally shared all of the pictures he took of the project that included sealing air leaks around fixtures, installing soffit baffles, a temperature controlled gable fan, and of course the new insulation. We definitely have noticed a difference in the comfort level of our home during this last week of high 90s that the new insulation has made. We totally recommend Ruben at Greenstar Attic Insulation if you are looking at reinsulating you home.

    This company did an excellent job upgrading the attic insulation in my house. Reuben is very knowledgeable and hard working. He uses excellent materials and equipment. The cost of the project to me was very reasonable and I am completely satisfied with the experience. I strongly recommend him and I am grateful he fixed my situation. Thank you very much Greenstar Attic insulation for

    It's been about a month since Evergreen (Ruben and his crew) installed new insulation in our 1950s…read morehome. And get this, we've only turned on the AC once (in the late spring we would have turned on the AC at least a few times). Of the other insulation companies I had contacted in the Sacramento area, Evergreen was the most prompt and professional. We needed new insulation for our crawlspace and updated insulation in our attic as recommended by a home inspector/structural engineer. We're glad we did because it feels less drafty in our home and the southwest corner of our house no longer bakes in the afternoon. My husband was very pleased when working with Ruben. Ruben clearly explained the issues in our attic i.e. accumulated heat, lacked ventilation, and the 70 year insulation had deteriorated, and made suggestions on what could be done. We were given multiple quotes to work within our budget. We are very happy with Ruben and crew's work as it is held to a very high standard. As a bonus, the crew vacuumed our garage because it was being used for equipment storage. They left it cleaner than when them came.

    We moved to Roseville last year and bought a house that barely had any insulation in the attic and…read morerat droppings everywhere. After Reuben came to work on it the first week, he said that they sealed up all the holes and added so much insulation. We asked for a whole house fan to be installed. They told us that it was out of stock and was delayed by six weeks. I called Home Depot and they said they had some great ones in stock and under $1500. We paid over $4k for everything. They didn't test the fan before leaving and took weeks to get them to respond. Turned out they had a big job in San Jose and couldn't be bothered. We had to call the manufacturer and my husband had to scale around the beams to get to the fan to sync the Bluetooth. Today, pest control found a dead rat in the trap and Atticman gave us a quote to fix their crap job. Airflow going from duct to duct instead of mixing box with duct tape that's fallen off.

    Well my experience with the company started out pretty good. I need a complete insulation…read moreinstallation done in my 2 story house. I was referred to this company through a post on the Next Door app. After sending a request for a quote the evening of Thursday 5/10, I received a reply early the next day, which was Friday 5/11. After going back and forth over the phone and through a few emails, an appointment was made for the estimator (whom I had been in direct contact with) to come out "next Friday at 8am", which would be today, Friday 5/18. Not ideal to wait a week just for an estimate but I was happy just to get the process started. In the week from setting our appt, i never heard anything from the company one way or the other. I took today off of work, was up early and ready for the appointment.... no one ever showed up. About 915 I emailed the estimator whom I had been in contact with and who replied almost immediately the previous Friday.... no response. Still. It's now 1pm. I'm not going to call and beg for them to take my money and for me to be their customer. Pretty poor though. I guess I get to research more companies and try to start this all over.

    My garage door had been sticking for awhile and then I met Darren at a charity event back in summer…read moreand he said they could fix it. He sent someone out right away for a service and the gentleman who showed up was polite, efficient, and professional. Finished in 30 minutes as promised and now my garage is working smoothly and more quietly. I would highly recommend ALCAL!
