10/10 recommend Carlos! My attic needed to be bought up to code to battle the Austin heat and being moved around after new ducts. I had another company quote me over 2x and nowhere near the level of service JC provided. He was quick and easy to work with and when I discovered there was a small issue, he came back to fix it same day. From inquiry to install, Carlos and his team were able to make it happen in 4 days. read more

No complaints about response time, workmanship and clean up after the work is done. I definitely would recommend them and I'll be using them again for other projects. Thank you JC Insulation! read more

Outstanding experience with JC Insulation for spray foam in my attic. They responded to my quote request the same day--faster than anyone else--and offered the best pricing with no hidden fees. They arrived on time, worked professionally and efficiently, and the foam application was flawless: even coverage, no gaps, and everything protected and cleaned up afterward. Already noticing better temperature control in the house. Highly recommend JC Insulation for reliable, high-quality work! read more

Requested a quote and he got back to me quick, was able to get the job started the same week. Job was to start at 8am, he called me at 7:55 that he was outside, right on time. Price was great compared to other estimates. Team also left the garage clean. Would recommend to go with JC insulation! read more

A++ service and fair pricing. Fast communication - garage attic was done in less than 30 minutes.

They got me a quote really quick, and then booked the install, showed up on time and worked hard. The end product looks great. Very happy with our transaction. I will use JC insulation again. read more

Five stars plus! Carlos was the only company I reached out to for quotes to assess my attic insulation in person, determine what was needed to bring it up to code, and provide an accurate price. Not only did he complete the work quickly, but he and his brother were also friendly and priced lower than the competition. I wish Carlos offered more services because I would definitely use him again. read more

Fast, quality insulation used, easy to schedule. Bid and worked on my home quickly and got job done within my budget.

Amazing team. Carlos gave me the lowest bid on Thursday and had the insulation installed on Monday. R38 throughout my entire attic in just a few hours. Would highly recommend! read more

Carlos and his team member were incredibly efficient when it came time to add insulation to my attic. I've been pleasantly surprised with how the HVAC system doesn't have to work as hard in this brutal summer heat that we're having at the moment. Knowing that Carlos was straightforward with pricing and transparency about how to go about either replacing or adding onto insulation was a huge plus, other places wanted to do gimmicky things like sanitize the insulation when there were no signs of pests. If you're looking for a really solid and well priced insulation team, go with JC! read more

I found that this company reviews on craigslist were very impressive, and called Carlos for free estimation. He came exactly at arranged time and gave me very good estimate for adding insulation on the attic of my home. Carlos and his brother Jorge came in proper time , made fantastic job very fast and I highly recommend them to everybody , who needs good insulation .. read more

Carlos was prompt and provided a solid service. He did blown insulation for a commercial space for us. I could easily recommend him.

I needed a new garage space insulated before sheet rock is installed, and yelp sent my info to multiple companies. Carlos wasn't the fastest to respond, but he was the first/only one that provided not just a range, but two specific price options (for R30 & R38), which also happened to be best pricing! He was also the fastest company to be able to do a site visit to confirm scope & cost, and due to my time constraint, he sent his brother to complete the job on the same day! Carlos/JC Insulation will be my go-to for insulation needs from now on! read more

Carlos and his team did a great job all around. He provided me a very competitive estimate chatting on yelp and he was onsite the next day to take a look at the attic. His actual quote was spot on with the estimate, extremely competitive on pricing, and he was ready to do the install 24 hours later. When Carlos arrived for the insulation install, he was early for the appointment, worked very efficiently, and did a great job. Big difference in temperature after his work. I got a variety of quotes for insulation but honestly you can skip all of that and just go with Carlos at JC Insulation read more

Carlos was one of the first to answer my request for quotes for attic re-insulation. He came out for the estimate and was super friendly and very competitive with the pricing. He updated his estimate when I requested additional services and he was still more affordable than any of the other companies. Carlos and his team arrived early, did a thorough job and completed everything exactly as quoted and spoken about. I would absolutely use him again for any further insulation projects we have. read more

JC came fast and provided a fair quote for the job I had him bid. He was very diligent in checking with arrival day of job and letting me know when they were on their way. He was so through and easy to work with. Here are pictures of the shed they insulated. I will happily use them again in the future. read more

Fast service, great prices. Would recommend to anyone. They came out at the expected time and it went well

JC Insulation is absolutely worth all five stars. Carlos responded to all communication super quickly. He came out to see the property the morning after we first reached out and sent us the quote within a few hours of his visit. His quote was specific and offered all the options we wanted to consider including the R-Values. The price seemed pretty fair to us. We had originally considered doing it ourselves but I guess because they get wholesale cost on materials the difference was almost a wash and spared us a whole lot of time and trouble. Carlos was early both times he came to the property and he texted us when he was headed over and upon his arrival. It took us a couple days to figure out what we wanted and Carlos followed up with a text to see if we needed anything else to make our decision. We had them add Knauf blow-in insulation, which is not their usual goto product, to what was already in the house and he was quick to order what was needed. He even thought to send photos of the material he had bought so we knew for sure it was what we had asked for! They added 11" of insulation on top of what we had to about 1500 sqft and it took just over an hour. There was minimal mess in and out. Most companies of any kind could learn a thing or two from JC Insulation! read more

Thank you so much for coming out so quickly, the price was great too. Professional and they cleaned up after themselves. Carlos was able to schedule me immediately. I felt safe with them in my home and glad I chose them after having bad experiences taking bids the previous year, I am grateful for Carlos and his team. read more

This is a good company; the rates are affordable, the work is good and Carlos actually listens to you and makes a real effort to meet your needs. I highly recommend this company. read more
