Once again, the team at Alhambra Insulation Masters provided exceptional service on my home. They applied foam insulation in my basement and successfully sealed an old root cellar that needed attention. Evan and Jay introduced themselves when they arrived, and they were very tidy, worked efficiently, and took the time to explain all the work they were doing. I've always had the same energy consultant for my projects, and I continue to be impressed. He came to assist Evan and Jay and showed real care for me, my dog, and my property each time he visited. I can't express enough how pleased I am with the company and their team. I highly recommend their services!
I reached out to Alhambra Insulation Masters after seeing great reviews about their services. I discussed my project, which was around 5,000 sq. ft., and received an estimate of $2,400, which I found to be an excellent price for a home that wasn't new construction. They sent Jay to inspect the area first, and I must say, he brought fantastic positive energy and was extremely polite and professional. The company is fortunate to have such a dedicated team member. I am very satisfied with the work done and wholeheartedly recommend them for your insulation needs. Reviews are essential for helping people make smart choices about businesses that truly deserve it. So, keep sharing your experiences, everyone! Wishing everyone good health!
Choosing Alhambra Insulation Masters was the best decision for our major renovation. We needed insulation for a new addition that matched the performance of the original home. Their team coordinated seamlessly with our builder and executed the work with master-level precision. Their attention to detail in air sealing and ensuring a continuous thermal barrier was remarkable. Living in the finished space, the comfort and quiet are exceptional. Worth every penny for master craftsmanship.

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.
These guys are the best! We are 100% satisfied with their work. The men were on time, efficient, polite, cleaned up after themselves and completed the job in hours. They got right to work, never stopped and were super considerate of us being home. We had insulation put in the attic but first it needed to be cleaned out and I don't want to know what they found. It is sparkling and all new insulation installed quickly! I would highly recommend this company for insulation.

I am thoroughly impressed with the expertise and customer care. Armour Montebello Insulation provided a science-based solution, not just a product installation. Their initial diagnostic was thorough, and their crew executed the plan with precision. They were careful to protect our belongings and left the worksite cleaner than they found it. The results are undeniable: a cozier, quieter, and significantly more energy-efficient home. Highly professional and highly recommended.
I can't recommend this company enough. After other contractors provided vague proposals, Armour Montebello gave us a clear, detailed plan that made perfect sense for our Montebello home. The installation team was punctual, respectful of our property, and incredibly tidy. They worked diligently and answered all our questions. The improvement in comfort is immediate, and we've already seen a positive impact on our energy bills. A trustworthy and highly skilled local business.
Our experience with Armour Montebello Insulation was flawless from start to finish. The quote was transparent and competitive, scheduling was convenient, and the crew arrived right on time. They worked efficiently as a team, were courteous throughout, and cleaned up impeccably. The before-and-after difference in our attic and the resulting home comfort is astounding. This is a company that operates with integrity and delivers on every promise.

In November 2024, we hired Top Energy to install ductless mini-splits in two studio spaces and the garage on our property. Leor was very responsive and knowledgeable, and helped us determine the location and size of the systems. Installation was one day; pricing was fair. The crew even returned to do several other handyman projects, which went well. Adding climate systems to these rooms has been a game-changer in how we use the space. Highly recommend Top Energy!
When both of our AC units unexpectedly stopped blowing cold air Top Energy Solutions was able to get a tech out quickly to diagnose the problem. It was discovered our system had a leak in the lines running under a patio. Leor came up with a solution for us and the next day removed the old systems and installed 2 new systems. The crew was efficient, professional, and did quality work. Because of that we had Leor and his crew come back the next day and insulate the attic and install an attic fan. I couldn't be happier with the communication, efficiency, and professionalism of Leor and his crews!
Top Energy Solutions is the best contractor I have hired. Leor is responsive and professional. I acquired three quotes to have my HVAC system replaced. I accepted Leor’s quote, and the installation started, and was finished by the end of the next day - amazing. A crane was required to remove and replace the AC unit on a three story house. His installation crew was very friendly and very good natured. He beat the other quotes by more than two thousand dollars for the same equipment. Leor is a general contractor and has crews for most home repairs. I will be hiring Top Energy Solution again soon.

They were very easy to work with, they documented all the work. In less than a week I had someone evaluate the work needed and complete. They were also way more affordable than 2 other companies I contacted prior to them.
This company is highly professional. They are punctual, professional, and efficient in their work. They removed old attic insulation, sealed air leaks around vents and lighting, and installed new rodent-proof insulation. The courteous workers handled everything, and our house was very clean when they left. I highly recommend this company.
These guys are so amazing they show up on time. They do a good job and the price was good. I highly recommend them because they are licensed and they use all the professional tools and equipment.

My appointment was at 0530 hrs but they start taking delivery from 0700 hrs. Early morning company trucks start loading for their jobs. Direction: if you coming from Barstow, from H-15 take left on 147 exit (Bear Valley Road) and left on I Ave and right on Catalpa St. Customer is on left side. Sign board posted on the building BDI installed. Park your truck, go inside of the building and back in when alley is free. Can park on the road at night buy no washroom available.
Delivered a load here. I had to wait 30 mins for them to get propane for the forklift because they weren’t prepared for the day. They don’t have a dock. So took another 2 hours to unload my dry van. Nice people but not the best setup.
Be carefull when it comes to Roofdeck. There contract says Rood deck, but in reality they mean roofdeck only above living space, not the whole roof.
