Carlos' company is fast and efficient. They came in at 8 AM and was finished by 1 PM to spray foam about 600 ft.² of my garage roof. You can tell they pay attention to detail because the garage was left cleaner than what I originally left it as. For my experience, many contractors tend to leave a mess behind sometimes for their customers which can be frustrating. For my research with close cell spray foam there is definitely a technique behind it for proper installation, and I am pleased with what I see. I did expect more fumes from the spray foam, but surprisingly the product they use has minimal smell to it.

My attic

I Called Carlos on a Sunday and he met me at my home 2 hours later. He was very knowledgeable in the industry and gave me a competitive quote. I agreed to the cost and the very next morning his crew arrived and performed the job. from the moment they left, I could feel the difference. I am so pleased I chose Carlos. He is also one of the most friendly persons I have met. I would recommend him for your insulation needs. He is responsive, professional, and personable Anthony Nuanes

Nice one stop shop. Wanted to insulate a sunroom to make live-able space and do Sheetrock/drywalling and install a/c vent and Carlos came through. One few companies out there that still does spray foam which was the best type of insulation for my ceiling given limited space and to optimize insulation. Also put batting on floors. Other companies told me could insulate but likely not feel much a difference due to many factors. Carlos gave a fair pricing and really believes in his work that on day of insulation he decided to toss in full all wall insulation at no extra cost! Amazing! He doesn't do dry want all or vent installation but knows people who do. Rather then being a "contractor" and charging me extra money just to use his contacts for drywaller and HVAC, he gave me their contacts and I was able to have a savings with great quality work. The room is very well insulated and I'm glad I went with Carlos. The other companies were wrong about insulation not making a difference especially when Carlos is on the job. Would use him again and recommend him to anyone especially if you have limited space to insulate and spray foam is what you need. He does all types but this was what I needed to optimize my insulation.

We're doing a major renovation on our house, and hired Carlos Insulation to do the spray foam throughout. They have done very good work, were extraordinarily easy to work with and flexible about timing, and offered competitive prices. Highly recommended.

Ceiling insulation

Carlos and his crew are top notch. He promises quality and great service and he delivers. Communicated throughout the whole process and cares about his customer's satisfaction. He followed up with me to make sure I was happy and had no issues.

Carlos Insulation really took good care of us. Much of the insulation in our crawl space had fallen down and needed replacing, as well as strapping up the rest to keep it in place. Not a big job, but an important one. I arranged the scope, schedule and terms with Carlos himself in one phone call. His team showed up on time, knew exactly what to do and finished in less time than expected. They were clean, professional and were even prepared to go under the house again to look for our cat (who was thankfully hiding under the couch). They also took before and after photos of their work that were quite valuable. A final phone call with Carlos before they left settled the price on the exact terms we agreed to earlier. On time, on budget, superior performance. That's what you get from Carlos Insulation.

Fast, reliable and honest! Carlos and his team went above and beyond for us. We live in an older home (built 1946) with no insulation. We were freezing in the bedrooms and were concerned for our newborn so much so, we ended up making our living room a bedroom as we have an electric fireplace. When sharing with Carlos our concerns, he immediately scheduled an in person estimate for Wednesday after only having connected with him a few days prior. We committed to his estimate and recommendations. By Thursday afternoon the job was complete, both in crawl space and bedrooms (2). The bedrooms are a lot warmer and we already regret not insulating the whole house. Take a leap, trust me, you'll be satisfied with services! Unfortunately, I don't have any during and after pictures of the project but, photos attached are of a completed job with new paint. You can't even tell we had work done.

Looking for insulation? Carlos and his team are the right people for the job! I reached out to Carlos and he was fast to respond, even on weekends when other companies don't answer. I decided to go with Carlos after reading his yelp reviews and after speaking to him. He answered all my questions and gave me a great price. We scheduled the appointment about a week out and they showed up and worked hard out in the cold. They kept everything covered and clean while they worked. I did wall and attic insulation. Really happy with their work. Hire them!

Carlos was very understanding how my house thst was built in the 50s had about no insulation in any of the exterior walls. Within a few calls Carlos came by the house, knocked on some walls with his knuckle and did confirm my suspicions. Gave me a quote for the following week and they were prompt. Even the walls that had some insulation, more cellulose was blown in to make them well cushioned. All holes drilled were patched up by the group and make for a good base for the next painting opportunity. Solid pricing and very accommodating.

A separate injection is made for each area, to be sure that insulation completely fills the wall space.

We had a very good experience with Atticare for rodent exclusion and attic modernization/insulation…read moreinstall. Our project manager Samuel Mor who did the initial inspection and coordinated the service went above and beyond to answer my questions, scope the work to meet my needs, and address what was top of mind for me in the job. The onsite team was professional, comprehensive, and efficient. I appreciated the team being very clean / safe with handling the insulation removal. We're very happy with the overall experience and already see a big difference in comfort from the new insulation in place.

I had AttiCare come out for an estimate to clean the attic and provide insulation at a rental…read moreproperty. The estimator's in-person presentation was very good -- professional, clear, and well organized. The overall process was explained pretty well however I needed more info after he left. The one key issue for me was the R-rating and since R-value is a major factor in comparing insulation options, I wanted to understand exactly what was being installed. I tried to follow up with the estimator to get clarification and asked for a call back. While multiple emails were exchanged from what seemed to be the corporate end, there was no actual human interaction, and my request for the estimator to call back failed. Because of that lack of follow-through, I ultimately decided to go with another vendor who was more responsive. AttiCare made a good first impression, but communication after the initial visit failed. I wouldn't proceed without speaking to the estimator. They lost a job due to that.

I had a crazy invasion of rats and mice. Crawls space was recommended to redo a job that 3 years…read moreago I had insulation replaced and the house was sealed by another company. Apparently the job wasn't quite on spot. Crawlspace Cleaners came in helped me get rid of the invasion, resealed my home and cleaned out the ruined insulation and replaced it in less than a month. With guarantees to return if it fails or even when it works to come back with in a year to do a check. The company is attentive and respectful. I wasn't made to feel guilty or pushed in using them. They are a family company not chain corporate. I would recommend them 100%. Thank You crawlspace Clean.

We have a crawlspace in our house that needed some TLC. Sure it provides a way to route air ducts…read moreand water pipes along with raising the house on pillars. However, crawlspaces can get moldy and wet from lack of care. If you ever encounter rodents, there is a good chance they came via the crawlspace. After all, we do hear noises at night at times, which is creepy. Jacob visited and gave a comprehensive review and estimate. We basically went for a full package of rodent control, cleaning, and installing a new vapor shield to keep it dry. The while job took maybe 2.5 days with a crew of 3 workers each day. Outstanding quality work. First phase was sealing up the homes around the house and crawlspace, and laying traps. The attic was inspected too. This was followed up with weekly followups to ensure no more rodents. This scope was subcontracted to Golden State Critter Control. Highly recommend working with Greg. The next two phases involve cleaning and eventually reinstallation of the vapor shield. Compared to what we had before, it was day and night! I also appreciated the crew alerting me to a leaky drain pipe. I later worked with a plumber to replace a cracked 3"D drain pipe that connected upstairs to downstairs. It was fixed in about 3 hours with two plumbers. Definitely recommend Crawlspace Clean for rodent control and crawlspace cleaning. 5 stars.
