"Geovany and his team did an amazing job at my house cleaning attic removing all debris lid insulation, sanitizing and air sealing attic, installing new insulation and radiant barrier. Job was done in a clean and professional manner. Team was polite and professional. I would recommend Fibers Insulation to anyone looking to upgrade or replace their insulation or just looking to add radiant barrier to their attic for a cooler more energy efficient home."

"Adam and his team of workers gave me a great deal on replacing the insulation in the attic. We had a leak in one of the fire alarm sprinklers that caused the insulation to be bad and smelly. 
We spoke to Adam about the problem and he sent his employee (Luis) to come over and check the problem in order to provide us  with a quote.
The quote that Adam was able to give us was very good and we approved the work. He than sent 2 workers to do the job and it was done in 2 days after they had to clean everything in the attic and to try it before they placed the new insulation.

"Excellent service and good people to work with! Adam was very generous to us when we contact the office and asked for their help with the problem at our house. The insulation had to be replaced based on an inspector requirements. 
The replacement work took 3 days in a row and the workers did a good job. we will hire them in the future.

"Our recent home remodel was pretty extensive. I knew I wanted to change some things, improve some things, and fix some problems with our house, but I didn't have any idea how to get there. From my initial meetings with Tony, I could tell that he was comfortable with the scope of the project, and that I would be able to work with him through all the challenges that I figured would come with a project of this size. Now that we've finished our project, I can say I'm glad we went with OM Construction. The price was fair, the guys were onsite 6 days a week from start to finish, and the quality of work was very good. During the project, Tony always had a positive attitude, and worked to help us solve a lot of problems with our old house ranging from framing, insulation, electrical, plumbing, doors, and windows. His guys did a good amount of finish work too, including stucco repair, laminate flooring installation, molding installation, drywall/skim coating, and interior and exterior painting. Marcos, Carlos, Josue and Elias were all very respectful while in our house and took extra effort to clean up well at the end of every day. Overall I think the project turned out great, and I'll definitely call Tony the next time I have a project I can't handle on my own."

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul.  The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic  was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made.  I could not believe the difference in our utilities bill.  Charlie and his team were great,  professional and experienced. I wish we did these 15 years ago!!

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Home Medics was on time, courteous, and changed out the filter in a timely manner. They did not try to sell an additional product or service like other company's do. They came and did what they were supposed to do. I was very pleased and will recommend them to others.

Insulation questions, answered by experts

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
