Im looking to buy a home that was just built. However, the yard seems to hold a lot of standing water and has drainage issues.

About how much would it cost to fix these issues? I’ll try to attach some photos for a better idea of what I’m talking about.

You need to either make the seller fix these or run far away. What the heck was that builder thinking?

If he did that bad on the grading, I'd hate to know what other crap jobs he did building that house

Did the builder build on a bunch of red clay?

If so good luck with drainage and getting any grass to grow.

Can that issue be fixed? Yes, using French drains and aeration for the grass with topdressing.

Is it a red flag that there are potential concerns that could costs $10k to remediate and might lead to water in your house at some point if not addressed? Yes

Consider yourself fortunate that you were able to inspect the site after a good rain before it was too late.

No way in hell I'd even think about buying that house. Too many issues to start with.

One pic shows your foot underwater next to the foundation.
You backfill that area and the soil is up against your bricks, not along the edge of the slab where it should be.

You will have weep holes in the brick on the bottom course and that could wind up letting water enter that area and possibly get indoors or at least start a mold issue in your walls.

I appreciate all the advice thus far. Is this fixable with gutters and the right drainage system or is it generally fricked from not being built up properly from the jump?

Hell no. Don't touch that...As of right now it's not your problem and you really don't want it to be.

I mean it should be fixable with regrading areas, gutters, and French drains but heck that'll probably take 20k to do right and then like I said earlier, I would be seriously worried about other parts of the house if the builder did that poor on the grading

Only one way to fix that - dirt.

Easy fix.

Tell the builder he can re-grade the lot (including French/area drains) to shed water away from the slab.

Or take 40k off the price. 20 for you to do the work, 20 for the headache.



He will do neither, and sell it within a month.

You can regrade and add French drains, but the water has to go somewhere. Can you tap into the sewer or will you send it to the neighbor's yard? Doesn’t look like an easy fix unless you definitely have somewhere downslope with the capacity to accommodate all that water.


I’d stay away.

Any consideration in buying this house would include having a civil engineer assess the property to see if a drainage plan is feasible.

What is the elevation of the property and where does the water need to drain. What is the elevation of the storm water drainage (if any) and how much fall do you have to drain the property.

This should have been considered before the house was built.

Ask the builder what his plans were for drainage. If none was considered, run.

FYI if you scroll down the page where you hosted you pictures you can copy from where it says BBCode and you paste it in your post, no need to use the img button.

How would you characterize the rain that did this? Normal, significant, or historic? Now imagine what it would look like if it was a genuine historic multi day rain event.

Is the property also getting water from uphill properties?

I could mitigate this with a few tactics, but I’m firmly in the run away camp.

As someone who has done a ton of drainage work on my homes, I see a ton of issues on new construction. Folks moving here (Ozarks) from CA will have some rude awakenings this Spring.

I would also want to know the history of the property. Was there previously a pond or a drainage canal that ran through it. If grading the property covered those former issues, the land might still be settling into those former areas.
