"We had an inspection and we had to replace the insulation in the attic. We were able to get a good deal from this company after we reached them via a referral. 
The work that they did was very good and professional. there were several employees at the house for the 2 days work that they did. We do recommend this company for any insulation replacement that you may need.

"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!"

"At this point, i can recommend this company in case you need to have someone professional, reliable and not expensive to work at your attic in case you will have any issues there. This company came over and replaced the insulation due to several problems that i had there.
Their price was good too and they came to my house in the time frame that was set ahead of time by their office.

"Joel at Quality Insulation is my first call for my insulation needs. We've done about 8 projects together and each time he is on time, efficient, and follows thru with what he says he's doing. Give Joel a call you'll be very happy. I've also referred him to a few friends and they've all been happy."

"I had Attic Fix Pro people take care of insulation for a new build. Their prices were very reasonable, better quote than I received from others. They advised me that the most cost-effective way for me to insulate the roof was a hybrid of Closed-cell spray and additional bats which would give me a R58+ value. It was a creative approach that would save me money and allow me to still have a very high insulation rating. Their crew came in to do closed cell spray insulation for the roof and the second time to do the bat insulation for roof and walls. They were super clean, laid down protection for plumbing, electrical, floors and walls; did their work, removed everything and cleaned up after themselves. Super happy with their work."

Insulation questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

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.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

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.
