*One of the most common issues with bathrooms is moisture. Especially here in the Vancouver area, we get lots of rain throughout the year, and it contributes to the already moisturized bathroom issue. You need to make sure that your bathroom ceiling fan is working well, cleaned, and connected to the proper venting outside of the house. To test your bathroom ceiling fan, you can take one sheet of toilet paper and place it against the cover of the ceiling fan, the toilet paper sheet should stay right up against the ceiling fan cover.
