"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

"** 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."

"We had radiant barrier insulation installed insteads of blown in insulation. It was laid in the attic rafters, upon the completion of the job the service provider could have done a better job of cleaning up. He also left some marking on our cabinet. When the gentleman came over to give us an idea of what radiant barrier is we never knew when he would be there, they gave us an estimate but then upon completion we wrote a check, but never received a receipt of payment, or work order showing completed work. All we had was the gentleman sign the estimate that we had been given two weeks prior to the job. And the installer did not have any paperwork saying that he did the job. But we had him write that on the estimate. I would expect more professional paperwork."

My wife and I did a thorough search in getting the best A/C Contractor in the Sacramento area.  The search included Angie?s List, Better Business Bureau, California State Contractor?s License reviews, personal recommendations from neighbors and friends.  After all our searching we ended up going with Diamond Heating and Air.   We signed the contract with Bob Weatherford who is also the owner of Diamond Heating & Air.

Both my wife and I were especially impressed with Bob?s thoroughness in explaining the type of system we really needed, the SEER rating of the equipment, and the best way of replacing the existing outdated  heating and cooling system, inadequate insulation, and faulty duct installation.   These were all good suggestions in transforming our home into a more energy efficient and comfortable environment.   Also, it was pointed out that some of the existing ducts became loose and disconnected.  Fiberglass insulation was blowing into one of the rooms.  The outdated  ducts were installed many years ago, and were poorly installed, wasting lots of energy, and the duct work was hanging too low below the floor joists.  

Bob suggested that the new duct system be relocated and strapped contiguous to the floor joists which would allow us to walk underneath the house so we could better utilize the space for movement and storage.  Another big task involved the installation of new attic insulation.   This was a big job that required the knowledge that Bob has as being a Licensed Building Contractor.  

Again, the thing I appreciated the most was Bob?s honesty and the effort he made to make things right.  Bob and Elaine worked hard to qualify us for the SMUD low interest rate financing and qualify us for the rebates that SMUD and PG&E were offering.  This helped us tremendously in bringing down the costs of the project.    My wife and I are extremely happy that our home now has an excellent home energy assessment from SMUD and PG&E.  We expect that our annual electric savings will be significant.  We are very happy to recommend Diamond Heating & Air to our family and friends.

Everything with this installation was flawless.  Willy and his team were punctual, professional and extremely knowledgeable.  We are thrilled with the work performed by Willy, Matt and another tech (sorry, do not have his name).  Paul was our contact with Ray O. Cook Heating and Air.  He gave us all the information we needed to make a decision and was quick to respond to questions we had.  Within one week we saw Jeremy on an emergency call (within 45 min.) had an estimate, and installation.  We would highly recommend this company.

"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."

Insulation FAQs, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

Yes, including recycled denim and cellulose from natural fibers.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.
