Get matched with top insulation pros in Challenge, CA

"I was happy with the job that was done. It provides insulation plus a vapor barrier. He put in a radiant barrier. It looks almost like tinfoil. They crawled around under the house installing it. It insulates better then conventional insulation. My house is warmer when it is cool and cooler when warm."

"** 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."

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."

"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."

"When I started, I planned to just insulate a small area over the ceiling of my laundry room, which was always chilly, and whatever else I could get for the money I had already put out for The Deal... Whereas Rudy clearly had in mind that the visit would be the beginning of a much bigger job,and my coupon only  the tip of the iceberg... not what I had in mind. But I thought I could at least hear him out,  and each project I asked about which I thought would have an astronomical cost, Rudy came back with what seem an amazingly reasonable price. whic included everything I could think of.  and when I asked for the next enhancement, that too seemed irresistably reasonable, and on and on we went til we got to the very large project described above.. At that point my whole house was insulated and ventilated as well as it could possibly be for a whole lot less than I would ever have thought possible, and I was just delighted. With each improvement, I was really afraid to ask, and then each time I got a nice surprise. I'm only sorry there was no way to insulate my vaulted ceilings, because they cover so much of my main living space.So then Rudy and his workman came back another day to do the work, they worked quietly and considerately, cleaned up perfectly, worked efficiently, were pleasant to have around, and everything went well.
There were just two problems during this transaction. The first was that Rudy could/would not accept a credit card for the job so I  had to get cash or check, which turned out to be an enormous problem for me at that precise moment in time.
The second was that in the process of installing the attic insulation, Rudy had broken the doorbell, wires  which run through the attic to a large clanger bell in the back. And he kept saying he would come back to fix it . But kept not coming. For weeks and weeks. This became very hot and hostile. Only when I threatened in a big way, did he finally show up, pay  for a new electric door bell I had purchased, and install it almost to completion.
.
Yet on the whole, Rudy was unusually pleasant and smart and sharp, good at explaining things, and a pleasure to do business with.
