Possible drainage problems- whom to hire ?

19 years ago

I went down into th crawlspace because the house smells unbearable. I found plenty of efflorescence on the crawlspace foundation walls and a huge 7 inch diameter patch of crystalline white stuff on one of the footings. I tlooked like a small crater. I dont know what to make of it.

the wood downthere seems to no be very damp, so I am ssuming it is groundwater coming up through the vapor barrier seams.

There was some water collected on the vapor barrier in some parts and nothing leaking above it.

So it seems like I have a drainage problem. I live near the seattle area and the house is built on a slope and I am sure they brought in fill to make up the ground when the house was constructed

I am not sure what kind of person to contact, my guess is a landscape contractor, and I am even more unsure of how much this thing is going to cost to fix drainage problems.

Can some one give me an average cost ? So I know what these things cost ?

What kind of questions do I need to ask these professionals so I know they know what they are doing ?

Thanks
