Great work, and good price. They came when scheduled, prepared the space very well, and installed all the insulation as agreed (with good craftsmanship). Would definitely recommend…

Josh was awesome to work with. We were having condensation issues with our upstairs shower ceilings and he identified the issue was from a lack of insulation in our attic. He gave us an honest assessment of what needed to be remediated and informed us that the job was far less than what we heard from other companies. His team had to complete the work in two stages and he prioritized our project on short notice. The team was efficient, respectful, and most importantly - clean. Couldn’t be happier with the result, the communication, and the price for the project. He saved us thousands of dollars and was extremely ethical. Highly recommend!

I had my house fan duct insulated and additional loose cellulose blown in today. My crew was Manuel, Eduardo and Ceazar.. They were prompt, personable and came prepared. We took a few minutes to orient them to the job, and then they went to work. They were all self-starters, shared the job between them, and did what needed doing. They wore coveralls and facemasks to protect themselves from the dusty environment. They laid plastic down with painters tape to keep the floors clean. They carefully brought the blow hose in thru the 2nd floor window, and made sure nothing was scarred or discolored by the hose. They built a solid sealed box of 1" foam board around my house fan duct so I would no longer lose heat there, and so the attic insulation could have its full effect. They made improvements to the hatch insulation, the hatch walls, the insulation of my bath room ducts and they leveled the insulation better than before. Manuel advised me on a better type of wrap for the ducts, and used the extra to wrap the hatch. I was very pleased with their work overall, and I appreciated not having to go all the way back to Brian to get sensible, useful information about insulation!
I highly recommend EcoTec and would hire them again if ever I need another insulation job.. Great work!

Waste of my time and no showed for consultation. Went to the website to get a quote. It makes you schedule the consultation. I scheduled it for a few days later and at a time that was available for selection and received a confirmation. No one showed up. Received an email 8 hours after the scheduled time thanking me for interest and offering me to schedule a free at home consultation. They obviously don’t value people’s time.
