“This may include ensuring you have full and adequate coverage in your attic insulation. For humid areas in a home, like bathrooms, particularly the primary, a humidistat used with the ceiling fan is an excellent device to ensure full extraction of excess moisture and air movement.”
For extra recommendations on cleansing, hearken to Edward Steele, proprietor of Cleansing Buddha. “At Cleaning Buddha, we believe in keeping homes spotless without harming the planet. Ghosting on walls — those dark streaks from soot, dust, and poor air circulation — can be removed naturally with the right approach,” says Edward.
He continues, “Start by identifying the cause, whether it’s poor insulation, humidity, or airborne pollutants. Then, use eco-friendly solutions like white vinegar, baking soda, or Castile soap to gently lift stains. Prevent future buildup with HEPA filters, non-toxic candles, and proper ventilation.

This dense material helps block thermal bridging and evens out wall temperatures, reducing condensation and particle buildup.”
“If you’re doing a renovation or opening up walls, batt insulation or spray foam can be installed directly,” he says. “Spray foam is especially effective, as it both insulates and air-seals in one step, minimizing drafts.”
“Once the insulation is upgraded, clean the affected surfaces with a mild detergent, prime with a vapor barrier primer, and repaint. Proper insulation not only stops ghosting but also improves comfort and energy efficiency throughout your home.”

Our homes often incorporate structural insulated panels (SIPs) and tongue-and-groove paneling, which help prevent thermal bridging — the temperature differences that contribute to ghosting,” she says. “By ensuring high-quality construction techniques, we create healthy, long-lasting timber frame homes free from unwanted streaks and stains.”
