Concrete block construction house

6 Replies

Hi there

I am looking at this house in Sacramento that could make a good flip candidate. I would have to add a master bedroom to the house though. The one thing that makes me a bit nervous is that the outer walls are built of concrete blocks and that does not seem to be very common around here. 

A few questions come up:

  • Do buyers in this area (Sacramento, CA) like concrete block houses?
  • Can everything be done as usual with this kind of walls? Electricity etc?
  • Can I overlay them with sheetrock in the inside? Is that something you would do?
  • We would have to knock out a wall for the addition. Is it a problem to mix concrete block walls with "normal" walls in the addition?
  • Any general advice about the concrete block walls? Total no-go? Is it actually a good thing?

Mostly I would just like to hear from other investors if they thinks this kind of walls could be a problem or not.

you'd want to stud it out and insulate and drywall so there is room for mechanicals and the insulation is key.

On the outside you could cover it with 3/4" plywood, tyvek and the Hardi or Vinyl .  I like Hardi personally it has a more expensive look and good brand .  Other option Stuco. 

You can't put drywall over cmu directly. Block are hard to drill conduits and tubes, hence the recommendation for stud and drywall, if you want it. Doable, not cost friendly moving pipes and conduits if they are in the walls. Your addition has a plan to transition from cmu to stud, personally I don't think there is an issue, but only your building and safety can answer that.

For cmu walls tou need to fur the walls out.

Basicly build a 2x4 wAll next to it.

@Simon Stahl  As long as the blocks and mortar are in good shape, it is no problem to renovate, or add on to, a block house. There are additional costs though, so factor that into your budget. If the numbers still work: great!

CMU construction is very prevalent in some neighborhoods around Sacramento. Tallac Village has a bunch; and I wouldn't hesitate at all to buy a CMU house there. I'd be more worried about the overall appearance than what it's made of. Some CMU houses look really ugly just because they were made as cheap as possible. If the rest neighborhood has better looking build quality, then I'd be hesitant. Then again, that could be all the more reason to get it cheaper. so if you think you could make it match the rest of the neighborhood, then maybe that makes it all the better deal.

Thanks a lot guys for the answers. This is pretty much what i thought, i just wanted some more folks to reconfirm :-)
