I scheduled a consultation and sought three other bids. The radiant barrier bid was by far the best bid for my 2200 sqft home. After booking the appointment several days later, the workers arrived two hours late. I was not happy with this portion however, their work was professional and very detailed. The workers prepped their work area, covered the floors, and completed their work. The whole process took approximately three hours (in addition to the two hours waiting), nonetheless I would use them again.
Description of Work: Sprayed radiant barrier in attic.

I called them up and gave me an estimate over the phone then I called again to clarify some stuff and gave me a different estimate on the phone. Apparently they looked at the house and gave another estimate on the job. So far they were quickly available for service when I needed them. They really have a good clean up job. They explained what they will do and what I needed to do for them to get ready to do the work.
Description of Work: I used the insulation services of Diversified Thermal Insulation.

Glenn Perrin, the sales rep, was very responsive when I called for quotes. He was on time and knowledgeable about the job. The job was quoted within 1 day. Price was the best I found. Work was performed as described when promised. The price quoted was the price paid. We are very happy with the work and the product. These are rooms that are not conditioned all the time, once the temp gets to where we want it it stays there without the HVAC running very much. I highly recommend Diversified Thermal for spray in insulation.
Description of Work: Used these guys to insulate a new shop in my backyard and my existing detached garage. Also got a quote for insulation in the attic areas of my house. That work will be done in the spring probably.

I was doing research on radiant barrier versus foam versus padding more blown insulation and we decided to go with foam insulation. They were very on time and very professional. They answered all our questions and they were nice guys. They took about a day and half to spray the foam in to the attic. They are very good. The foam is more expensive than doing some other things but I think in the long run it will pay you off. They did come in, worked with us on what we exactly wanted to do and they ended up doing that. They did a second bid because we wanted something different, so they did that. They were very easy to work with. They did a really good job. I didn’t find any gaps in my insulation.
Description of Work: I used Diversified Thermal Insulation about three or four weeks ago.

The job was too small so I didn't use them. They gave me the input where I could do it myself. I ordered the chemicals online. It was colossal thermal insulation type of job and it was so small but they had $1500 booming fee. They ordered the chemicals, much then needed to the job I did myself. It was really nice that they gave the input. During the close sale they had a minimal fee. It was more than a big work and I could do it myself. I really liked them because they were right up front with it. The guys in sales didn't want to let know and ensure that I don't go somewhere else but they knew I wouldn't do it at such a high price so they told me to do it myself. They were nice enough to give the inputs I needed. They were here on time. They were very professional.
Description of Work: Diversified thermal insulation gave me the estimate online and the advice on the insulation work. The last time I used their service was 2-3 months ago.

They arrived around 8 AM with 3 guys. They were finished around noon. They allowed me to inspect their work. They left an attic light on that I had to turn off but they had informed me of this. One of my insulation contact recessed lights now periodically turns off if it gets too hot due to the insulation covering it. My bid says it was supposed to be Applegate brand cellulose but the invoice says it's Celbar so I'm not sure which brand I got.
Description of Work: Diversified Thermal Inc blew cellulose insulation to R-38 (10.5") in my attic of my approximately 1600 sq ft house and 400 sq ft of the pool house attic. They also installed some type of thermal material around my 5 non-insulation contact recessed lights.
