Had two men from Lilianthal in my basement to put in insulation. The one guy was super rude and didn't bother saying hello. He pushed past me to use the bathroom in my home not once but twice and stunk up the whole house. Then I heard him hucking luggees in my basement. I was too scared to confront the situation because he looked dangerous. My dog wouldn't stop barking and I had to kennel him because he could tell this guy was bad news. I feel violated, disrespected, and I am completely shocked by this bad experience. I will be cleaning my house now of all the dirt they tracked in as well as clean my bathroom, and hope I don't step in a luggee that the vile man spit in my basement. I feel like I need 1,000 showers because I am completely disgusted!!! I do not recommend them if you want peace of mind and a clean house! read more

Outstanding service.  We have been remodeling our home for the last couple of years.  We have an older home here in the valley, and when we started the remodel we found that our house had little to no insulation in it.  How anyone could keep this house warm during the winter is beyond me. So, last year after insulating the walls we hired Lilienthal Insulation to come in and do our attic.  They were suppose to get the R-value of insulation in the attic to over 40, but the installers who did a fantastic job and were extremely thorough thought they got the R-value to over 60 when they were done.   All I can say is the proof is in the bills, and this past winter our heating bill was half of what it was the previous year.  The cost of having Lilienthal insulating our attic is about the same as if I would have done it myself.  The difference is I could have never got an R-value as high as they could and what took them 3 hours to do would have taken me a week.  They are worth the money. read more

We are so grateful and impressed by the team at Lilienthal!! They did a great job and ended up finishing our job ahead of schedule despite the bumpy road of construction timelines with delays. The crews were friendly, punctual, and professional!! We are SO happy with their work!!! read more

"inspector" came to my home to check an issue with attic insulation and caused over $400 in damage to an air return duct. Company refused to compensate me for the damage caused by their employee. read more

Poor service. Didn't complete job, left areas of the house not finished. Save your money and hire a different contractor. read more
