"I obtained 3 bids via Home Advisor and 3 different companies showed up to quote it. As price went, Attic Elite was the middle of 3 bids, but I was the most impressed with the professionalism of the Attic Elite rep of the 3 who showed up. And Attic Elite provided the written bid electronically within a few minutes of leaving my home. I waited almost a week from another vendor and 2 days for the other one. Neither of the other 2 offered vacuuming, disinfecting, and deodorizing of my attic space. Neither of the others offered patching of holes for rodent infestation. I feel I got way more value from Attic Elite as compared with either the higher or lower other bids. As far as the work went, it was better than expected. They did insulation batts in the lower crawl space. Insulation batts in the ceiling and blown in to all of our (mostly stucco) exterior walls. After those hole patches in the stucco were done by Attic Elite, it was hardly noticeable other than needing paint. Here's what was beyond what I expected. My attic was full of 50+ boxes of stored items. I didn't need to remove them. They took care of it and neatly stacked them in my garage! Theyfoam sealed everywhere that vertical sheetrock met horizontal and anywhere there were gaps of any kind. That's something I wouldn't have thought of. They replaced damaged vent screens that had holes and foam sealed around them. They cleaned up after themselves like they were never there. From initial quote visit to when they were done, they were polite, professional, clean and thorough. No high pressure sale. They were done in less than 2 days. They had a standard price list and it was what it was, and they showed pictures of how they do what they do at the time they quote it. And provided pictures of every area as they completed each portion. As to what I had done, I'm really happy with it. Sure I didn't like spending the money, but my heater was running constantly before in the winter and the ac running all summer. We could always feel a breeze in the house if it was the least bit cold outside. Our hvac was always running resulting in high gas and electric bills. By the end of day 1, the ceiling and crawl space insulation was in and we already felt a huge difference and the heater wasn't running nearly as much. After the blown in walls were done on day 2, our heater was almost never running. Mind you, it was done in February and really cold outside. Since the install, we're leaving the heater mostly in the off position. What a huge difference. I'm not one to write reviews. But I wanted to take the time to write this one. I've already recommended Attic Elite to my neighbor and won't hesitate to recommend them in the future. Outstanding job. Worth the money. Highly professional. You can't ask for more than that."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"I didn't write down his name, but the person I spoke with on the phone gave me good advice on what to check for to see if there was anything amiss. He didn't offer to come over (their office is not close to my house) but I felt his approach was very reasonable and it was helpful."

"We had an inspection and we had to replace the insulation in the attic. We were able to get a good deal from this company after we reached them via a referral. 
The work that they did was very good and professional. there were several employees at the house for the 2 days work that they did. We do recommend this company for any insulation replacement that you may need.

"Every person that came into our home from Tri-County was very professional and respectful.  They covered everything with plastic before removing the insulation and again when blowing it back in.  They cleaned up and disposed of the plastic, vacuumed the attic and cleaned up after themselves such that  you would never have known they were here.  The job of sealing the attic was done so well that the inspector made a comment that he had never seen a job done as well as this and ask who had done the work.  He gave them very high praise.  

The salesman we had, Bryan Zailer, was very knowledgeable and helpful.  He would call back immediately if we had a question and stop by to check on things.  I would highly recommend Tri-County to everyone for their insulation needs."
