They truly built us a better thermal nest.

I manage a small rental property in Simi Valley and I've used Quiet Home for three different units now. They are consistently reliable, fairly priced, and the tenants always tell me how much more comfortable the units are after the work is done. The last job was a top-up on an old attic that was settling badly. They showed up exactly when they said they would, finished in a few hours, and the property manager didn't have to babysit them. If you own rentals in Simi, put these guys in your phone.

We built a new home addition and knew proper insulation was critical. Trusted Seal Insulation was the obvious choice based on their reputation. They coordinated seamlessly with our general contractor and installed insulation in the walls, ceiling, and floors to the highest specifications.

Their expertise ensured our investment was protected and performance was maximized. Outstanding service from a top-tier company.

Our heating system no longer struggles, and we've already seen a significant drop in our energy bill. The name says it all—they are truly trusted, and the seal they created is exceptional.

Good home service

We called Bright Nest Insulation after enduring another sweltering summer with an AC that couldn't keep up. Their team identified that our attic insulation was not only inadequate but also improperly installed in areas. They completely redid the work with precision and care. The crew was professional, efficient, and left everything immaculate. The comfort level in our home has improved exponentially, and our energy bills are finally under control. Exceptional service and results.

Choosing Bright Nest was one of the best investments we've made in our home. The process was seamless, and the results speak for themselves. The crew was efficient, worked together like a well-oiled machine, and left the worksite spotless. They focused on the science of building performance, not just laying down material. Our heating system no longer cycles on and off constantly, and the overall ambiance of our home is just more comfortable. Top-notch professionalism.

I cannot say enough good things about this company. We’re new homeowners and they took the time to educate us and give us very fair quotes. They were prompt, honest and super thorough with their work. The owner was personally texting us updates and sending photos throughout the entire process. Would definitely recommend this place to anyone getting insulation or air duct replacement! Amazing value for sure!

My experience with Pure Eco was outstanding, I was able to get my attic done in 1 day of work with a quick, courteous, very professional crew by Armando. I didn’t replace my air ducts since I moved into my house 12 years ago, I lost air flow and the layout was horribly messy, they need to be changed , it was the original ducts system, I had noticeable temperature differences in most of the rooms around my house after we checked the attic we noticed that there is no insulation at all but roofing debris. I am very pleased with the ending results. Thank you Armando for making that happen!

I would highly recommend Pure Eco for any house insulation projects. We had really old insulation in our attic that hadn't been replaced since we moved in a few years ago. We were also affected by the Eaton fire so we were concerned about any potential ash and debris that may or may not have escaped our initial inspector's notice after the fire. Many thanks to Beni and his meticulous handling of this job. He came out to provide an estimate on a Monday and had us scheduled for our insulation to be removed, cleaned, and replaced with new, eco-friendly material by the next Tuesday (mind you, it was 4th of July weekend as well so timing might've been even quicker if not for that). Shout out to Andres, Romeo and Anthony for the amazing job they did for my family's home. They came exactly on time at 8 AM and went straight to work. No dilly-dallying, just straight up efficiency. They were pleasant and professional to speak with throughout the day. By 3pm they were done and left the house clean. Amazing experience, highly highly recommend.

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.
