"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation questions, answered by experts

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

Periodic checks for moisture or pest issues ensure consistent performance.

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.

Upgrading insulation enhances energy efficiency, noise reduction, and indoor temperature regulation. It leads to cost savings on energy bills, improved home comfort, and reduced environmental impact, increasing home value and livability.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.
