Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"We had a problem where rats used to get in the attic via the air spaces. This big problem caused an infestation that required us to solve this problem and to replace the insulation.
Adam from Attic master,  was very nice to us and understood the problem very well. He sent to our house one his main guys to check and see how he can help us solving this problem. As part of his great service, he was also able to close all the openings on top of the new insulation. 
I'm very happy that 1 company could solve this problem once and for all.

"Tony and Green Apple were awesome. He gave a quote and stuck with it, even when the job turned out to be more extensive than he anticipated, showed up 15 minutes early (after giving me a courtesy phone call to let me know he was on his way), and worked very hard for three hours to clear at least 30 years of dust and debris out of the duct work. He had a sense of humor, respected the property, left the house clean and ducts spotless. Don’t hesitate to use Green Apple!"

Insulation questions, answered by experts

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.
