    Attic Kings - Hello I'm Moshe the owner of the company I'll take care about anything you need!

    We found Attic Kings through Yelp, and had a really great experience! Ofek and Moshe were…read moreresponsive from the start, which made the decision easy after their consultation. 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!

    Earlier this year I hired Eco Performance Builders install a new heat pump system, remove my old…read moregas furnace, relocate equipment into the attic, replace all ductwork, remove existing attic insulation, air-seal the attic, and eventually reinstall insulation. The experience was outstanding from start to finish. What really set this company apart is that they actually performed proper Manual J load calculations to size the system--something almost no other contractor I contacted was willing to do (load calculations are code required by the way). Every other quote I received assumed a system size based purely on square footage and would have resulted in a dramatically oversized system. Instead, this team took the time to measure, assess, and design a system tailored specifically to my home's demand. They even performed a blower door test to quantify air leakage--another thing no one else offered. As a result, I ended up with a 2.5-ton heat pump. Meanwhile, all other companies wanted to replace what was there (4-ton) or go even higher (5-ton). One company wanted to put in a 100k BTU furnace which is absurd. Their design work was thoughtful and meticulous. The Manual J and Manual S calculations they did ensured that the system was sized properly including duct sizes and lengths. They showed attention to detail with locating and aiming registers to reduce duct lengths (less energy loss due to being in the unconditioned attic) and to improve comfort (limiting air blowing on you in bed). They also took care to locate the ducts so they can bury them in the future attic insulation as much as possible. The on-site crew was excellent--friendly, respectful, and professional every day. They kept the workspace clean, coordinated work around my partner's daytime sleep schedule, and were incredibly flexible with scheduling overall. I've had to push back adding attic insulation multiple times so I can do a few attic projects first, and they've never complained or made it an issue (I still am not ready and they are fine with it). The resulting system has been working great since they installed the heat pump and air sealed in May. The system is basically silent and my house has been quite comfortable. I'm pretty sure the system has been more efficient than my old furnace based on my energy monitoring system that measures current to the unit and PG&E bills from last year, and this is without attic insulation. Regarding cost, you would think that EPB would be significantly more expensive especially considering they will do the proper design work. However, I got a few quotes additional quotes and EPB actually end up significantly cheaper than all other companies that didn't include any real design work! In short, this is the only company I found that actually does things the right way, prioritizing proper design and customer satisfaction. I thought this would hurt the bank but it didn't. I'm extremely happy with the results and would recommend them without hesitation.

    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. Same experience -- fast, solid workmanship, and a very reasonable price. Overall, really smooth process and great results. I'd definitely recommend Chris's Insulation Services!
