"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

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

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.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.
