I'm seeing a fair amount of new construction built on slabs these days. Any input on advantages/disadvantages of slab vs. crawl space construction?
I'm looking at new construction in Vermillion/Huntersville, and the sales person there is saying that they build on slab to make the homes more energy efficient. I suspect that might be true to an extent, but probably they do this because it is cheaper.
When I lived in Florida, nearly all the homes were built on a slab. However, there were certain areas that were notorious for bad foundation performance, due to a layer of clay (which, of course, is omnipresent in the Piedmont). The idea was that the clay tended to shrink during dry weather, causing cracks in the slab, settling, etc.
I'd appreciate any thoughts you may have on this issue, or any experiences.
Slabs are about $4K - $5K cheaper for builders than crawl spaces. It's always going to be their preference unless price point (usually 300K +) dictates crawl because of the aesthetics and at that price point you can usually pass the cost along to the buyer.
Most builders have 10 - 15 year warranties on foundations and structural related issues and while some slabs will have issues (as will crawls), most should be just fine.
Additionally, most slab lots are padded with good dirt to help prevent any of the above related issues.
I will never live in a slab-floor house again if I have the choice. The floors are very cold in the winter. When the slab cracks (and it will), expect termites and other bugs in your house. If you ever have plumbing problems, your floors will have to be jackhammered at great expense and inconvenience.
The worst part, though, is the sheer hardness of the floor and the fact that it does not give. As you get older, this becomes *very* hard on your knees as opposed to a floor over a crawl space or basement.
And, I may be wrong on this, but I believe it can make plumbing/hvac/electrical problems more difficult to fix as the pipes and wires don't just run under the house where you have easy access. I think with less access you are more likely to have to go through walls/floors for repairs.
Hi Comfort Food! I just have two thoughts for you on slabs...and they echo the others.
1. Tile floors on slabs will FREEZE your feet...my parents hated standing on my bathroom floors during the winter in the last house I owned in Charlotte. The floors were so cold, even the carpeted floors.
2. I had a perpetual problem with my heating/air conditing unit. The repair company finally determined that either the house had settled onto the tubing and pipes running under the house to the unit or that there was a discharge problem. But because the house was built on a slab, there was no way to check without ripping up my flooring.
To permanently fix the issue, they wanted to rerun all the connections between the outside unit and the inside unit through my attic, but...alas, that could not be done because the pitch of the attic was so steep workers couldn't get from one side to the other. It was a real pain, and something I never did get fixed. The result is that every year I had problems with either the compressor or the capacitor on the heater. It was infuriating not being able to get the root of the problem fixed.
As for a crawl space, my parents have this set-up, and the only disadvantage I see is they have to exterminate under the house periodically because they live near fields.

Our ranch home is 20 years old,no problem.If installed properly,pretreat soil for termite protection,visquene,mesh and monolithic pour it will be fine.My home had termidor treatment several years ago.This slab on cement blocks.
I have a slab and this is my first (owned) house. It seems like it is colder all the time, no matter what the temperature is. Previously, I lived in homes that had heated basements. It did not take as much to heat the upstairs that way, even if the heat in the basement was on low. Personally, if I ever move, my "new" house (and I would only buy an older constructed home) will have a full basement in it.
We are also looking in Vermillion and had the same question. You must have spoke to the same sales person..lol.
We keep ending up back there. We searched the entire area in 1 week and feel very happy with Vermillion. We are waiting to see what 2 other builders have for inventory homes.
Good luck with your search...we may end up neighbors.
