"I wanted insulation blown in above the ceiling of my condo to lessen the noise from my neighbors above. Darren was very responsive and professional and knew exactly what I was looking for. The crew arrived on time, was very nice, and covered the house in plastic sheeting to protect everything from the incredible amount of dust created by drilling dozens of holes in the ceiling to shoot the insulation. Their subcontractor Robert arrived the next day to repair the holes and repaint the ceilings. He also was able to install can lights in my living room (separate job and quote from the job Attic Construction was doing). During installation of the lights, we discovered that some of the cavities that should have been filled by new insulation were not, due to a problem with the old insulation. One call to Darren and the insulation guys showed up early the next morning to take care of it. Robert the drywall guy and his helper Carlos did an amazing job repairing all the holes, you can't even tell that my ceiling looked like swiss cheese at one point. The reduction in sound coming from upstairs is noticeable due to the new insulation and I love my new lights. Be aware though that a job like this is incredibly messy and dusty but Attic Construction OC made it as easy as possible."

"Strongly recommend getting an energy audit completed on your home, especially when it's complimentary, thank you, Paul! There were quite a few items that needed attention in our home. The technicians Justin and Fernando were solid. They arrived on time, did a great job, were polite, and were very clean. They took before and after pictures, which shows how much I needed the work done. We went with the insulation to ensure it was at least 18 inches, the duct sealing of the junction boxes and HVAC unit, and we had to reroute the bathroom vent. We even did the optional UV-C light, which makes us feel much safer and takes a load off, especially in this current environment of being conscious of germs and all. Great technicians, great company, and solid work. Highly recommend Justin and Fernando :) The email and text reminder game is on point."

"These guys are the BEST. They treat your home as if it were theirs. Isaac found some possibly faulty electric wiring in my attic and told me about it. He did not have to do that, because it delayed their finishing their job by a day, and interrupted their next job. But he is honest in decent and wanted my home to be safe. They removed all of the old insulation, replaced my ductwork, and blew in new insulation. They were kind, courteous, and professional at all times. The other two estimates I had did not alert me to the need for new insulation, and one company never even looked in my attic. I highly recommend this company, without hesitation. They are fair, honest, And worth every penny. I feel safer now and I know I am breathing much cleaner air."

Insulation questions, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.
