Wet Carpeting In Hallway
Wet carpeting anywhere in your home is not a good sign.
The wet carpeting in this hallway is from a roof leak. The leaking roof
has caused other damage to the home and will continue to cause
additional damage if it isn't repaired soon.
First and foremost, repair the roof leak. If the leak isn't visible and is hard to locate, you could always cover the roof with plastic or some sort of waterproof tarp. This will keep your house protected, until the roof repair can be made.
The wet carpet will need to be dried out as soon as possible. This can be done in a couple ways.
If you have a wet and dry vacuum, use it to remove as much of the water as possible out of the carpeting. When you reach a point, where there is no more water going into the vacuum, but the carpeting is still damp. You can run a high-speed fan, over the carpeting, until the area is dry.
Most rental yards carry carpet drying fans and this would save you the expense of purchasing your own. Hopefully you will never need them again. You will know that the problem has become serious, as soon as the people at the rental yard know you, on a first name basis.
Home Repair Tip: Make sure that the carpeting, drywall, ceiling, and anything else that is visibly wet gets dried out as soon as possible. This will prevent mold and mildew, most of the time.
Now for the hard part, it's going to be very important that you check these areas for any discoloration, for at least a few months. Any discoloration could be a sign, that the areas weren't dried out enough and now there is mold growing in your home.
