"A representative at Sam's Club set up an appointment for the next day. The gentleman who showed up didn't know insulation so he said that someone else in installation would need to be brought in. Four days later I was called and they set up an appointment for an insulation installation specialist. He was a no-show. I called in and was told that my husband needed to be there. Their rep at Sam's Club had never mentioned that so I asked to speak to a manager. The manager rescheduled for the next day. They were a no-show the second day. I called in and explained that I was the decision maker, so they scheduled to come out the next day. They were a no-show the third day. When I called in, the rep I talked to had inaccurate notes, saying I had cancelled. She then hung up on me. Don't use these folks, they like to strong arm people."

Insulation questions, answered by experts

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

You don’t need to remove old insulation before adding new insulation. As long as the old insulation is still in good shape—not wet, physically damaged, or moldy—then you can stack new insulation on top of old insulation to get a compounding effect. You can also mix different types of insulation, like adding blown-in insulation around existing fiberglass batt insulation or installing rigid insulation boards over rafters in your attic that already have batt insulation installed. If your existing insulation is very old or damaged, though, you’ll likely see more benefit from removing it and replacing it instead.

Freeze-proof faucets can still benefit from insulation, and they will need covers if you live somewhere with extremely cold winter temperatures. These faucets work with a design that keeps excess water in the pipes inside the home to minimize the risk of freezing, plus a downward slope for any water flowing through the pipes to keep moving. But keeping a cover on all faucets, even freeze-proof fixtures, is the best way to avoid frozen and burst pipes.
