"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

Insulation questions, answered by experts

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

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.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.
