Hey guys!

I have a question about crawlspace humidity.

I live in an old house (c. 1914) with a huge crawlspace. It's approximately 75ft by 25ft, staring at 10 ft ceilings at one end and going to 4ft at the other. It has an earth floor covered with a vapor barrier. The space is not sealed, but there are no gaping holes to the outside either.

The humdity in this space in the summer is constantly between 70% and 80%. I have talked to several people about this and have received 2 different pieces of advice. Half the people say I should seal it up and get a whole house de-humidifier down there, and the other half say I should put in air vents or an exhaust vent to get outside air circulating. I am very confused by this as they seem to be opposites!

Any advice you could offer will be much appreciated.

Many thanks!

Matt.

Since you did not post your location.

It is harder to respond if your floors are insulated it would not matter where you lived i would go for ventilation. For a few reasons.

It may eleminate Radon gas. And it is passive. No system to break down, no pipes to clog, no electricity.

However if you live in a cold climate with a huge variance between temperature. Those vents would need to be shut in the winter. And do you know the humidity level in the winter. You did not say.

Thanks for your response. I live in Atlanta Georgia. Average summer temp is about 90 and average winter temp is about 35. I do not know what the humidity is in the winter.

Would you mind explaining why the vents would need to be shut in Winter please?

Many thanks again for your response.

Matt.

If you have pipes running through there you may risk them freezing.

I am guessing below grade. no vents that risk is practically nil.

i would suggest the vents for circulation. it makes more sense than having a de-humidifier.

No dehumidifier is needed. That would be an unnecessary hassle
