Doorbell Installation questions, answered by experts

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.

Improves water efficiency, reduces oversight, and enhances landscape health.

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.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.
