Insulation questions, answered by experts

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

EIFS (Exterior Insulation and Finish System) siding can last from 20 to 60 years, with some properly maintained systems lasting even longer. The exact lifespan depends heavily on several factors, most notably the quality of the initial installation and the consistency of maintenance.

Factors that can shorten the life of EIFS include:

  • Improper or poor-quality installation

  • Moisture intrusion

  • Damage from high winds, storms, or hail

  • Damaged flashing and sealant

  • Lack of regular maintenance and unfixed damage

To maximize the lifespan of your EIFS, it is crucial to hire an experienced and qualified professional for the installation. Additionally, regular maintenance—such as cleaning, repairing small cracks or blisters, and having the system professionally inspected—will help identify and resolve issues quickly, preventing long-term damage.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.
