Basement Humidity After Rain Storm

I think if we get anymore rain up here in the great white north we will need to build an ark

No one can tell you the answer
Kinda like the farmers almanac predicting the weather
That water won't stop falling around Fingerlakes creeks and gorges humming.....lakes to the brim..

Gutters are probably the best solution. I know the struggle myself; we have an old house with fieldstone foundation. Water gets in with heavy rains sometimes. That and up here in the northeast US it has been like frikkin rainforest. Somebody tried sealing the walls with a rubber “flex seal” type of product but it just made lots of bubbles full of water form which had to be popped and then the water still comes right through. We run 2 dehumidifiers when moisture/humidity is high and even that is not enough if there is water puddling on the floor.
For a short term way of drying your basement go to any home store and find something called Damp-Rid. They are like little buckets full of desiccant that help dry out indoor areas. Get the un-scented kind unless you want your plants to smell like fake lavender or whatever. We put these out after heavy rains & basement is bone dry after a couple days.

Thats brutal, i figured that would happen, with the flex seal anyways. i cant believe someone actually tried it.

Yep… a prior owner basically made a big mess. I was told in order to totally seal the basement in addition to installing gutters I needed to dig out about 3-4 ft around the outside of the foundation all the way down to the bottom and then apply a plastic house wrap to the stone foundation & backfill with gravel. Never did it though; cost = astronomical. So it’s an uphill battle against moisture…

Damn got more water in my basement as we speak, I'm running 2 dehumidifiers... In the city our water drains into the sewer pipes from the gutters.... I need to my foundation to dry out, I can't have humidity near 60% with weed down there. Hoping that the humidity returns to around 50% once all this water we got (record setting almost 4" in a week) dries out.

How much should gutters cost to install/fix on a house that is 800 sq feet? I have gutters just need them fixed so they work properly.

Can gutters lower basement humidity?? 99% of the time I have NO water down there, but I'm assuming water sitting around the foundation of a house can raise basement humidity?? Thanks

I have a dirt crawl space with plastic sheeting. But when the river rises the water table will rise and it fills the crawl space. Takes a year to dry out and until then it's high humidity in the house. :(

Either remove the water or raise the temp of the air.

If you do it get quotes for 6" gutters. Should be able to get it done for 15-1700 if you are willing to hire people off Craigslist etc just make sure they are insured and have references

You can grade around bushes and shit. The goal is to have it slope away from house. Get 6"gutters and some dirt and it keeps the water away from the foundation. Trying to seal it from the inside just causes the water to find the next path of least resistance.

I would try either grading or gutters. Grading will be a lot cheaper but will require you/ friends/ fam to sweat a little. If that solve the problem then you fixed things for a few hundred bucks. If it doesn't solve it gutters will be a lot cheaper than doing the dig up/ outside wrap option.

Once you get the water away from your foundation you will actually be able to control the humidity down there.

I've never heard that 60% humidity is so high you should be concerned about it. My humidity stays around 60% all summer long with a dehumidifier running 24/7, Idk about anyone else but it's hard for me to get much better than that with these great lakes surrounding me. You should be fine though, when full blown winter hits my humidity goes down to like 40%

Depending on location a ranch that size is probably the company’s minimum which around my neck of the woods is $500
Make sure it is a company that makes your gutters on the job
You don’t want vinyl gutters either

I've had Raingo vinyl gutters for 35 years. Last year they needed a tune up as the seals were dry rotted on the connectors and I finally put a leaf guard on them. Only complaint was I had to clean them 3-4 times a year. The leaf guards have this down to once a year now. Norway spruce needles and locust tree leaves. :(

I think the Corona my have put them out of biz though as they filed bankruptcy. I'm looking for some special 90* downspout connectors. fittings and can't find them.

Lots of flex seal? :lol: I would not worry too much about 5% increase.
flex seal liquid is crazy expensive now. it seems to be just some naturally occuring mineral in a solvent...forgot what's it's called and the msds is really hard to find...it smells horrible...like that kind of smell like hmm this probably will give me cancer lol
and the flex seal spray is 40% calcium carbonate...

@Meast21, just wondering what the issue is regarding your plants and I apologize if it was spelled out and I missed it. Are you concerned with growing or drying or both? I have an unfinished basement that can get very damp if I don't run a dehumidifier. I keep it set at 55% or 60% depending on outside conditions. This keeps the basement humidity level 57% which is perfect for drying as I do not wet trim in order to get a slower dry (usually 8 to 12 days). In the tent the humidity gets down to 50% with the light on and climbs to the low 60s during the dark period which the plants seem fine with.
