"The guys did a great job for an affordable price . During covid with a supply issue still managed to get the job done right ! My attic was at 160 degrees during the summer I have dropped it down to 85 to 90 . Do not worry about your old insulation being removed your attic will become a conditioned space left over insulation will result in moisture that you don't want in your attic .Great job guys best of luck to you ."

Insulation questions, answered by experts

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

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.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Yes, an automatic pool cover retains heat. It can act as a thermal blanket because the heavy vinyl traps heat underneath, keeping the water warmer than if there wasn’t a cover. Keeping the pool cover closed when the pool’s not in use can also help reduce water utilities and save on pool chemical costs because there won’t be as much evaporation.
