Add-ons for better air circulation in basement
I'm having a problem with mold appearing in tight spots in the basement which is probably due to poor air circulation. We renovated the basement last year, replacing all wood boards with drywall. The walls before were cold but we added some insulation to it. The floors are tiled but remain cold due to it being the basement floor underground. We didn't really add any vent as we continued with the layout that already exist. After noticing the molds, we thought it may be due to bad air circulation and not enough ventilation.
I would like to know if there is anything I can do now to make the basement more livable with air quality...like add some holes, vents, buy some add-on to the furnace etc?
Any help would be greatly appreciated!
