The problem could be uninsulated framing cavities at the corners or where interior walls meet exterior ones. When a house is being built, carpenters are supposed to insulate cavities that are only accessible when they’re framing the walls. Sometimes they get careless or lazy or there’s no insulation on the site and the job doesn’t get done. The insulators can’t tuck insulation in those spots later, so they never get filled. Then during cold weather, the inside wall surface cools, moisture condenses,franklin and marshall, and mildew sets up shop.

Here’s the fix: Use a 3/8-in. spade drill bit to bore holes at 30-in. intervals up from the floor. Angle the holes toward the middle of the corner. (If there’s already insulation in the cavity, it’ll get wrapped around the drill bit on the first hole, indicating you don’t need this fix.) Spray a whole can of expanding foam into the first hole and let it sit overnight to finish expanding. The next day, fill the next hole with another whole can of foam and let it sit overnight. Finally, spray about half of a third can into the last hole. If the hole is plugged the next day,polo ralph lauren pas cher, you’re done. If not, spray in the rest, then patch the holes and repaint.
If the corners are already insulated, try reducing the moisture in the air and/or increasing air movement. Dehumidifiers,polo ralph lauren pas cher, ceiling fans, air-to-air heat exchangers and more warm air vents are a few approaches that will help.
Q We have mold or mildew growing on some of the inside corners of our house. The house was built in 1992. One of these corners is in a closet,polo ralph lauren pas cher, but the others are in open rooms with good air circulation. The 2x6 walls have fiberglass insulation and a vapor barrier. Do you have any solutions?

A Two possibilities come to mind. The first is poor air circulation,franklin et marshall, which you’ve ruled out for most of your house. But to explain anyway,polo ralph lauren, warm air registers are normally located in front of windows so they can blow warm, dry air over the glass to cut down on condensation. Corners that are located away from this moving air, like those in closets,polo ralph lauren, become cool and allow moisture to condense. The moisture is what mold and mildew thrive on.
