I had Ram Insulation help with my attached garage project. They showed up on time with three-man crew and completed my 20' by 20' garage insulation within a day. They have done very nice and detail-oriented work and my garage looks brand new and ready for the next step.
Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.
Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

Omar and his team are incredible! They installed a complete new HVAC system in my 1950’s ranch style home. Prompt, communicative and professional. I would recommend them to anyone looking for a complete installation or just a tune up. Worth every penny for the peace of mind!! Thank you Omar!
The company really cares that their employees do an all around excellent job. I previously used Service All-Stars to replace my heater. Now they have installed my A/C unit. They do excellent work.The techs were friendly and informative about the details of the work they were doing. I appreciate the fact the workers worked quietly and efficiently. The owner is receptive to constructive criticism which is a big plus in my book. I will continue to call upon Service All-Stars for my HVAC needs.
The team that Sal sent (Brandon and Evan) did a fantastic job on repiping my 60 year old house here in Long Beach. I found a leak in my tankless water heater closet and called them out to take a look. My house has a slab foundation and turns the leak was coming in from the main-line under the soil and then through the concrete to the water heater closet in the middle of the house. They dug down through the concrete and rather than just asking the guys to patch the galvanized pipes, I figured it best to do a full house re-pipe through my tight attic since the plumbing is 60 years old. Good thing because in the process, another leak was detected in the wall between my bathroom vanities. The guys were friendly and hard-working, the process took 4-5 days and I was informed of where they would have to cut through the walls to connect all the pipes. They definitley routed the pipes in the least invasive way. They also tuned up my HVAC system and tankless water heater while they were here. I would highly recommend Service All-Stars for your plumbing and HVAC needs. -DC
