If its just damp a fan or space heater might work.
If its sopping wet, you might try a carpet cleaner. This might suck most of the water out. Don’t know if it will get the moisture out of the pad though.
If that doesn’t work you might have to pull up that portion of the carpet and let it air dry.
If this house is relatively new and air tight, there could be a risk of mold. So going to drastic measures to get it dry would be better than going to drastic measures to remove the mold.
Just finished a rehab with new carpet, but a new supply line underneath the sink leaked and caused about a five foot arc of wetness on the carpet. What’s the best way to get out the water and keep it from smelling?
In addition to the other suggestions, bring a dehumidifier in and let it run to remove moisture from the air. This will allow the carpet to dry faster.
If you just finished a rehab you must have a “shop vac” floating around, no? Use the shop vac to suck up as much of the water as you can. After you’ve pulled all the water you can out, empty the vac, reverse the hose on the vac. It is now a blower, if you can get the hose under the carpet thats the best way to help dry it out. If you can’t get the hose under the carpet, use a fan, or the vac if you have to, to move air over the damp surface. Good Luck.
