"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."

"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.

"Outstanding quality, especially in custom designing what is called a cricket flashing to go around a chimney, the corner of the house and a valley which all converged at the same point.
Once the old roof was off, we found approximately $1700 worth of dry rot that needed to be replaced.  I felt the crew, particularly Mike Gibbs, did an excellent job of helping me understand the problems and then pick the best solutions to correct the problems.  Their price for the extra work was extremely fair and the again the quality was excellent.  We ended up replacing all of the fascia boards and the final result looked better than the original (and it was Mike's idea of how to do it).
In addition to the roof, they blew in some additional insulation in my two level attic to bring it up to an R-38 rating.  There were two spots that I felt might have been just a bit short and they returned promptly and filled in those spots by hand ... no questions asked.
For what it might be worth, the building inspector, when I told him the work was done by Brazil, sort of muttered under his breath "Good, they do it right" as he climbed the ladder to look at the roof.

"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

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

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.
