Basement is humid, Also floor is uneven

Hey everyone. My family bought a new house ( our first actually ) and while it's not in the worst shape, it does need some work. We are looking to work from the ground up, and the first thing that comes to my mind is the basement floor.

The whole basement itself is "finished" but I have a feeling it is just some paint thrown over the concrete walls. We are looking to re-paint the walls a kind of a light creamy flat color, so that it won't reflect light.

The basement is also pretty humid. Do you think a simple dehumidifier would take care of this problem?

Also, the floor is uneven. The floor kind of sinks in the middle of the basement, but I am not sure how deep it sinks. It felt like maybe 2 inches, but I am not sure of anything yet. What are the solutions to a uneven floor? The flooring right now looks like vinyl flooring, or maybe some kind of tile. Maybe hardwood flooring?? I really have no idea. Please make some suggestions

Well that was a rant, and my first post. Thanks! :)

If the basement walls are painted and you have high humidity there may be moisture issues.
There are many folks using masonry paints to try and seal leaking foundations from the inside.

Definitely use a dehumidifier to try and keep the humidity down. If you find it's running constantly for an extended period then you have to look for the source of the high humidity.

You need to control the humidity level first before you invest time and money finishing the basement.

If you decide to use hardwood or laminate flooring make sure to check the manufacturer's specification regarding the recommended humidity level for the product. Measure the value in your space to ensure it isn't higher since these products will be greatly affected by moisture and expand.

Regarding the floor .... it's hard to tell from here ... if it's cracked all around the low spot this might indicate it has sunk.

The methods jkirk mentions .... self leveling cement or sleepers and shims would work.

However...... it may also be the low spot may be a slope toward a floor drain.

Just 2 cents . :)

I'll definitely be getting a dehumidifier for sure.

The basement floor is not cracked, it just slopes toward the middle by a couple of inches. Also, there is no floor drain ( or not one that I can see )

How about just sticking a sofa or couch over the low spot? It would cover it up and we could place shims under the sofa legs appropriately to make it look level. We do have a unused futon that we have. How 'bout it?

Also, do dehumidifiers take up a lot of energy? If it is running constantly, how much would it cost in electricity bills?

Our basement also includes a boiler room ( unfinished ) and a laundry/bathroom. Would either of those two affect the humidity problem? I will also try to take the humidity reading sometime.

Re: Basement is humid, Also floor is uneven

Well as I was working on the house today I found that while there is a noticeable slope on the basement floor, it wasn't enough to bother me for now.

As for the humidity, I think a dehumidifier would suit me well for the moment, and if it is needed, we will take further steps in the future.
