"Charles was awesome all around!! Came out for an inspection, advised me of issues and the route I should take. We followed through and couldn’t be happier with the results, and how easy the process was. We got a full encapsulation with a dehumidifier and the difference in the air is amazing. Highly recommend if you are thinking about getting your crawlspace encapsulated!"

Insulation questions, answered by experts

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. 

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.
