5 Star Performance Insulation, Inc.

5 Star Performance Insulation, Inc. handles insulation work out of Sacramento with Gary running the show. They cover spray foam insulation along with attic, wall, cellulose, and metal building jobs across Sacramento, Truckee, Stockton, Elk Grove, and nearby spots. The company makes house calls for free quotes and focuses on cutting energy loss through roofs, walls, and other areas. Gary has worked with customers on projects from design phase through completion, and the outfit has been around since the mid 1990s.

Homeowners call them for spray foam in rafters and gable ends, blow in attic and wall insulation, crawlspace work, and drill and fill jobs. One customer had Deven and Jose level closed cell foam in rafter bays before drywall, which kept the house warm when nights dropped into the thirties. Others brought them in for perimeter walls and attics during remodels or to fix cold floors in crawlspaces that stayed above sixty seven degrees afterward. Gary has driven out multiple times to plan jobs an hour or more from Sacramento, and crews finished some Tahoe homes in a single day while leaving spaces clean for the next trade.

Gary and the crew show up on time for most jobs, communicate during the process, and clean up thoroughly at the end. They quote competitive prices that often come in lower than other bids, and a few customers noted honest assessments where the team said no extra insulation was needed. Work covers Sacramento to Murphys and Fair Oaks, with some jobs taking four days when the site is farther out. Reviewers mention punctual arrivals, reasonable costs, and crews that stick around for years under Gary, though a couple noted canceled starts that pushed timelines back by weeks.

Google shows a 4.3 from 24 reviews with praise for results on comfort and energy use mixed against complaints about scheduling. Recurring notes cover professional crews and solid outcomes on temperature control alongside a few cases of delays or product debates. DIRT Score 3.4 from reviews on Finds.

“Gary, the owner of 5 Star Performance helped us plan our project. We live 1 to 1 1/2 hours out of Sacramento. Gary made several trips to our job site to help us get ready for the insulation. He was always professional and easy to work with. When we were ready for the insulation, his people showed up on time and were very professional and nice. Our project took 4 days to complete and I got to know his employees. They are nice guys who have worked for Gary for 15-20 years. Having employees this long only happens when the owner is a good person and fair. I highly recommend this company for all your insulation needs.”

“Its definitely 1 star .I had to trim my entire home because they didn't know when they could return. I needed to keep moving my home along the building process .there were several other issues property getting damaged. Thankfully they left me plastic wrap for their job.I worked 9 hrs on my bid job.This company earns money hand over fist and couldn't finish my job in a timely manner. I the homeowner finished their bid and will not hire them for the rest of the property”

“Gary and his team were fantastic. They worked with us on a tight schedule to get our Tahoe home insulated before winter. Clear communication and professional work - they finished the job in one day. Our lower level is now air-tight and incredibly warm. Absolutely recommend them without reservation.”

“I've worked with 5 Star Performance Insulation for the past sixteen years. Gary and his team are courteous, timely and knowledgeable professionals. They focus their energy on meeting the unique needs of each and every customer. I highly recommend 5 Star for any and all of your insulation needs. Cheers!”

“We had 5 Star insulate the addition and remodel of our home in Murphys. Gary and his team were very professional. The entire process met and exceeded our expectations. Clean up at the end was very thorough and our space was ready to dry wall. The past year we found the interior temperatures to be comfortable summer and winter. We seldom need to turn on the air conditioner. We will be scheduling them again to insulate the new master bedroom suite addition. Highly recommend 5 Star Performance Insulation and would give 10 stars if that were an option. Part 2 Gary from 5 Star deserves 5 Stars, 10 stars if that were possible. This was the second time they have come from Sacramento to Murphys to do an insulation job for us. The first time was on an 800 sq ft addition and we gave them 5 stars then. We did another 600 sq ft addition and wanted open cell below the ceilings and closed cell in the attic spaces. The team of Devin and Jose did an impeccable job. They even foamed around the windows and doors. The space was left cleaner than when they started. They were very professional and courteous. The cost was very fair. We highly recommend 5 Star Performance Insulation for all your insulat”

“Had Gary and company spray foam my Sacramento House. They did the all perimeter walls and attic area as we were doing a complete remodel. Later I had them come back do the same for the garage. They did an excellent job, cleaned up thoroughly, price was reasonable and they were punctual what more could you ask for!”

“We first contacted Gary with 5 Star when we were still in the design phase of our project. 18 months later we were finally ready and Deven & Jose came out to apply closed cell spray foam insulation in our rafter bays and gable ends. In places where sheet rock will go they brought all foam level with the face of the rafters. Afterwards they cleaned up very well. If you are considering spray foam insulation, it was immediately noticeable. The last few nights have been in the high 30s, the whole house is livable, not just the room with the furnace! Very excited to see how it handles the summer heat!”

“5 Star Performance Insulation was extremely professional and attentive to all our needs. They saved us tons compared to other quotes. I would reccomend Gary and his team to anyone in the area looking for great service and a good price!”

“I've used them twice now, to install spray foam in our garage and workshop, and then to do drill and fill in our walls. The price was fair and the work was quality. I'd recommend them.”

“I used them about 2 years ago now and I keep forgetting to give a review. To start the quote they gave me was 1/4th the amount of another company (which contracts out to this company anyway). They did blow in wall insulation and blow in attic insulation. Let me tell you, they do not take any short cuts! My boyfriend now refuses to go up there and every time a professional has to go up there, they come down looking like they just walked through a snow storm and are traumatized. They all do the same thing, come down, literally SHAKE the insulation off of them and under there breath mutter "that's a lot of insulation". Every. Time. They've earned their name!”

“Had Gary and the boys out to my Fair Oaks home. They sprayed foam under the floor and across the attic of my house. What a difference it made. It’s way to keep the house warm in the winter and cool in the summer. My son who lives close by stopped over at the house the other day and asked what temperature I had the Ac at. I said “ it’s not on” Worth every penny”

“I can't say enough good things about Gary and his staff at 5 Star Performance Insulation. They are extremely professional and passionate about what they do and take care of their customers. This is a great company that I highly recommend!”

“Gary was a total pro and up front with all the costs and timing on finishing up my summer home. I Would definitely recommend 5 STAR if you are looking for a quality work to be done and fast.”

“I truly wanted to do business with this company. From the initial phone call, dealing with the owner, it was a great experience. However, once I was contacted by the Sales Consultant (who supposedly had 20+yrs of experience), he immediately made it clear that he was doing me a favor, (poor mindset), then continued to debate me as to what the home needed versus what I preferred. In addition to this, he also attempted to claim that Certainteed Blown in was NOT and superior blown in product, over cellulose. After attempting to provide my email for further communication, he said “I do not email, I show up to properties, and if that doesn’t work you can call another company”. Mind you, this was after I shared several details regarding what 3 other companies shared with me. All in all, he was very dismissive and made me feel as if I needed him. Not the other way around. It would seem that after his 20+yrs, he has forgotten that PEOPLE ARE FIRST, and a positive first time impression is everything in sales. Again, truly sad, since I enjoyed the Owners conversation with me prior. I sadly will not be recommending this company.”

“STAY AWAY! This company is not reliable and definitely far from a 5 star service provider. They have canceled on me twice and pushed my timeline out each time by 2 weeks. This last time they canceled, it was the morning they were supposed to start. And then told me they couldn't start for another two weeks. DO NOT even engage them. You will regret it. Believe me, there are better companies out there that are reliable and offer good service. They need to get their business in order.”

“Last summer we had our crawlspace, which ranges from 2.5ft to 4ft in height insulated. Our floors would get very cold (as low as 60 F) during the winter months. This winter even with our below freezing nights our floors have never gotten below 67 the difference is amazing. The employees who worked under our hose were professional, on time and left the house clean, not one drop of anything on our hardwood floors.”

“Great job!! Showed up on time. Fast and efficient. Workers were polite and cleaned up after themselves when they were done. Pricing was competitive. Love doing business with locally owned and operated companies. Thank you VERY MUCH for the great service. JD”

“I asked for a 2nd opinion where I had been quoted $4600 by another supplier. Rich quoted $2000 but also told me that my savings would be 10% or less of my bill so probably not worth it. Nice to get an honest assessment from an expert.”

“5 star came out and gave me an honest assessment that I didn't need more insullation and gave me free tips about how to better circulate the air in my house. When I do need assistance in the future, I'm definetely calling 5 star :)”

“These guys are top notch!! They were very helpful insulating some interior walls as well as adding insulation to other parts of our house. Expeditious and professional. Thank you, Gary!!”
