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

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
