The were very communicative before the project, calling twice to confirm and ensure the address and street directions were correct. They showed up on time and did excellent work getting everything insulated and gaps blocked. The blower test was ~2000 for a 1650sqft home (1:1.25 ratio) before and 1300 after (1:0.79 ratio) the work which is great for a 35 year old home. They kept the house clean by using a lot of drop cloths for walking and even double insulated the side door that we rarely use to get our savings even better. I highly recommend the Worthmore Group and look forward to working with them in the future!

Some here have gone into detail as to how you can screw up a basic insulation job, so I won't repeat it. The number of screw ups and amateur work quality was more than I've ever seen in 30 years of home ownership and contractors work. The highlight: they core drilled through structural 2x4s inside the wall, under window framing. Who the F does that?! Everything from communications, to quality of work, to damages, to explanations, to billing / paperwork, slop/mess/clean up, it goes on. Ghosting communications to the office and field lead. Yes, they came back to fill in the various areas where they put NO insulation at all in several wall cavities...but, really, how do you just miss that unless you've been on the job for about a week. The only reason I got them to do that was I got a temperature gun that showed several places where it was a cold wall... They came with a IR image gun and verified various empty areas. What kind of training and qualification do they go through? and oh yea, one of the crew wanted to sit in my hallway for long periods of time, because his feet were very cold and he had nothing to do. When he was 'working' he was on his phone talking and texting non stop. I am not making this up. On each of two crews, there was one person of the three that was competent and able to communicate reasonably well, and two who were not. They meant well, but just not up to the task. Find a real insulation company with a real crew of adults.

As other reviews mentioned, Curtis and his crew carefully protected our (brand new) hardwood floors with lots of tarps, threw plastic over furniture and vacuumed after each day of work. Our home feels so much warmer and I am already seeing savings in my gas bill! I couldn't be any happier with their work.

Mark took whatever time was necessary to air seal in our unconditioned attic, install baffles, and also ensure that the insulation which was poorly placed on the surface was cut down properly so it could be in contact with the attic floors. I don't know how much energy savings air sealing will do for me as my newer house was already pretty comfortable before embarking on this project, but I am confident that this project has been completed in the most competent manner possible. I did receive quotes which were a lot less than Mark's, but still chose to hire Mark for the job since he seemed like he was going to take the time to do it correctly. After seeing how big a job it was, I really don't feel confident someone would have been able to do the job right at those lower quotes. The project ended up being about 4.5 days of work where Mark had to crawl through insulation for many hours to get the job done.
