"** This review is posted on behalf of my friend who recently used their service ** I can't say enough good things about Rich, Conrad, and his entire crew. First and foremost, these guys are 100% professionals. Do not overlook professionalism. I received other quotes from people who were either unwilling to do the full spectrum of work requested or not thorough in the initial review. We recently moved into a 1920s home that had old and brittle insulation laid around knob-and-tube wiring. So not only was the attic insulation ineffective, it also presented itself as a fire hazard. To make matters worse, there was a relatively inaccessible portion of the attic (i.e. access through a child-sized square cutout) they'd have to work their way into. At the very day/time of the appointment, Rich had already gotten to the house early (let in by our floor guy) and already ventured up into that tiny crawl space in the attic to assess the work. He made all of his notes and took photos before I even realized he was there. Keep in mind, insulators from other companies did not even bother to poke their heads into that space. When I mentioned what our ideal timeline was, Rich said that if they couldn't fit the work into our schedule, they would refer us to other companies they trust. Needless to say, I was impressed by his honesty. After receiving a quote via email from Conrad - who is on top of everything with phone and email communications and reminders - we decided that they were worth the three weeks wait. I signed the quote and we agreed on a start date. Conrad sent a reminder email a few days before the work was to start. The guys came on time and worked all day to remove the old crumbled insulation. By the end of the day, they were covered in black fiber/soot. They found all types of things around the attic that we weren't aware of - head boards, window screens, lumber, etc. They even removed most of the junk for us. A week later (after we brought in the electricians to update the wiring), they came back to lay the insulation batts, apply the batts to the walls where stated, air seal openings, and create a seal for the attic crawl space access cutout). They were able to complete the job over the course of a full day (9am to 7pm). They are professional, honest, thorough, responsive (emails were always returned timely and in that one week away, Rich returned my call to answer an insulation question), always on time, fairly priced (better, even), and skilled. And on top of everything else, the whole crew was fun to talk to. I couldn't have asked for a better experience. I would recommend them as your #1 choice for your insulation needs."

"Old shake roof was removed, new insulation added, plywood base with roof paper cover. Then tiled over raised battens. New gutters and downspouts. Dry rot repairs and painting of new surfaces.The whole process took four days. The bid and contract were presented very thoroughly, each item of work detailed and priced. Many choices. The work crews were very pleasant. The work was done in a set order and a company rep would call to inform of the next step and when it would happen. At the conclusion of each days work the property was cleaned and as tidy as possible given the nature of the project. When finished, a company rep inspected the job and checked for any needed corrections. All in all, an outstanding contractor to work with."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"we were very impressed with out solar endeavor. The installers came when they said they would and finished their job within the same day. We added insulation to our attic to reduce our heating and cooling for the house and replaced 2 old windows . All the guys were great from Idan who evaluated our home, office staff and installers. We are very happy. "

"An unanticipated extra expense, but they removed all attic insulation and pumped in new insulation with 3X the protection. Closed up all possible entrances into house; made three trips. So far, no signs of these pests, but they say call anytime if I see signs. I'm moving and I can't -- with good conscience -- sell this house to others knowing it had rodents, although it didn't seem to bother the people I bought the house from."

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."

"Due to some renovation and repair work, there were large areas of ceiling over the kitchen and master bath where the insulation had been removed. The rest of the house had old cellulose insulation that had been settling for several years. All in all, in the winter cold the lack of insulation was noticeable. RJL Installation ran a special with a discount on Angie's List to pay $149 for $500 worth of installed attic insulation. I bought the special and was contacted by RJL. I was really only wanting the areas where insulation was missing to be covered, but it turned out that the cost was not much greater to get the entire attic covered. I was somewhat taken aback by the total price ($1,149.50 on top of the original $149.00), but decided that the insulation was needed in any case, so that was why I gave the C rating for price. I felt a bit trapped because I had already paid for the discounting and didn't know how to get that money back if I had decided that I didn't want to pay as much as the final quoted price.
The installer thought that there should be some sort of access port or window or something to get into the attic from outside the house, and seemed surprised that the house was built with only a hallway ceiling opening for attic access. Once we established that that was, indeed, the only way to get up there, the installer proceeded to bring a large hose through the front door and the hallway and into the attic. When he was in place, his assistant started feeding compressed bales of fiberglass-like insulation through a machine that broke up the compressed insulation and "fluffed" it and blew it through the large hose to be blown in place. When the installation work was completed, I was invited to climb the ladder to take a look at the coverage, using a large flashlight as my light source. From the ladder, the insulation looked to be level across as much of the attic as I could see (almost all the attic, in truth), and appeared to be deep enough to be effective. When they were finished with the installation, the installer and his assistant borrowed a broom and managed to sweep up almost all of any insulation that had found its way to where it was not wanted.
All in all, an acceptable job. I thought about giving an overall rating of B, but except for the price, the other categories rated an A.
