"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"I needed to fix ceiling insulation after a major leak into the living room. The insulation was pulled up to allow things to dry out, but the company that did the drying (Stanley Steamer) said they would not put the insulation back. I called Ace because of all the great reviews on yelp. The bid was $650. I accepted it, and an excellent workman arrived on time as arranged. Here is the rub: The workman was finshed in 1/2 hr (!!!!!), and my jaw dropped. I thought for the price must be going to take at least a few hours. I had agreed to the price, though, so I wrote the check, as well as an email to the estimator for the job explaining how distressed I was by this. The email was passed to the manager of the Sacramento office, who called me right away. He said he would have felt the same, and that he would tear up the check and give me a new price. We met the next week, and he charged me half of the original bid. He gave me my original check and took my new check for $325. Here is what you should know about the price: The invoice had two *Service* items: a *show up fee* of $250, and another called *Work performed as per quote. This was followed by a *Quote adjustment based on actual work* of -$325. I truly appreciate the businesslike approach to the work: On time, done right as best I can tell. I also appreciate the response to my distress over the clear miscalculation. In spite of this, I feel overcharged even at half the original quote. The *show up fee* should have covered everything, so the maximum bill should have been $250. There was extremely little work performed, even if it was done well and professionally. In retrospect, I have no idea what the estimator included in $400 for *Work performed as per quote.* What did Ace do wrong? The estimator should have seen there was less than an hours work involved and told me that the minimum charge would be $250 to show up. If there were other minimum charges, such as a minimum of an hour of work, those should have been explained by the estimator so that I had some basis for understanding the bid and the opportunity to decide that the price was possibly going to be too high. The estimator said nothing about this, and there was no detail in the estimate. I believe I have given a fair revue for this disappointing experience. Ace has excellent customer service, and as best I can tell, the work was performed well. The pricing at first was way out of line, and ultimately still seems to me to be too high. But the job is done, and I am sure if there is any reason to, Ace will stand behind their work."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"I hired Attic master to come over and check the attic for some bad smell. Adam came over to my house and went up to the attic and checked the problem there... He recommended me to remove the old insulation and to place a new one. His price and warranty were good... so i hired them. The following morning, he came over with his worker and took out all the old insulation while his worker placing the new one. The work was completed the same day and the problem of the bed smell has been solved."
