How to Repair a Deteriorating Window-Well Retaining Wall

  • Transcript

    LESLIE: Don in Wisconsin is dealing with a window-well retaining wall that’s coming apart. Tell us what’s going on.

    DON: We have a window-well retaining wall that has – have railroad ties in there. Been there for quite a few years. Has started to deteriorate and I’m just now – I’ve been trying to check on what to do and been told to try to use retaining blocks and put blocks on there. And then you have to put some kind of a pea gravel in front of the block to hold the sand back, because we have sand here; it’s a sand country.

    And I’m not sure. I never did this before. And I was just wondering if it’s something that a person – because I’m handy – be able to do myself or is there something that you should actually have a professional landscaper do?

    TOM: At the highest part of the wall, from the distance between the ground and the top of the wall, how high is that?

    DON: Thirty-two inches.

    TOM: OK. So it’s fairly low to the ground. Alright. I think this is project you can do yourself. Concrete blocks – the interlocking, retaining-wall blocks – are a terrific option because they’re very easy to install. Because it’s only 32 inches off the ground, it’s not a lot of soil for you to deal with. You’re going to take the wall apart one sort of area at a time and build the blocks as you go.

    The thing that’s going to be different about the concrete blocks, though, is you’re going to have to have them on a bit of a solid footing. Now, that’s one that you might want to create yourself. You could probably create that out of stone that’s well-tamped down. But you’ve got to get them sat nice and level; you can’t just put them right on the dirt, OK?

    And then as – after you assemble them, then you can add the pea gravel behind it and the sand behind that. But I do think that that’s a good option and it’s going to be – literally, if you do it right, you’re going to get a lifetime’s worth of satisfaction out of that because, of course, the blocks are not going to rot.

    DON: Oh, OK. It sounds great.

    TOM: Alright, Don. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
