Hello again, Geetha:
Well, the one biggest problem is that if a house with a slab needs termite
control, the treatment can be very expensive. So by the time any slab structure reaches the age of about
20 years, the termites will, by then, have found their way into the structure. Might happen before 20
years, might happen after - you can never tell for sure. And if the heat vents are cast into the slab
(vents in the floor rather than the wall) proper termite treatment might be impossible. It is VERY difficult
to treat a house, with heat in the slab, for termites.
Not only that, but there are many practical
reasons too. First of all, it is much harder to care for the utilities in a slab house (plumbing, electric,
etc) whereas a house with a basement or a crawl space you have access to all of these things. Also,
the floor level of a slab house is usually only inches from the ground and this makes it much easier
for any kind of bug to enter. A basement or crawl space is a "buffer" for all these things.
It
is much cheaper for a builder to build a house with a slab because he then doesn't have to worry about
the substructure - the slab is the substructure. Additionally, concrete slabs ALWAYS crack somewhere
- look at a sidewalk or a garage floor - you almost always see a crack (or cracks) somewhere. The more
cracks you have, the more chance there is for things to come out of those cracks. I have a lot of customers
with slabs that have constant problems with pavement ants coming up - pavement ants live under all concrete
slabs, and if there's a crack they'll come up. You can see this happen in the winter too - don't forget,
the slab is heated - something that pavement ants (and termites) appreciate!
As far as I'm concerned,
a basement gives you extra space to store your stuff. It's free space - if it's a full basement, you
have added that much area to your house already. I'm usually against finishing off basements also.
If you finish a basement, you've covered the substructure and you can't see what's going on. If you
have to have the plumber or electrician in, you might pay a premium for his services. Not only that,
but he might have to tear into your finished areas, making a simple repair quite expensive.
Houses
with unfinished basements are not usually any more expensive than houses without one - unless you're
buying a new house or having one built. Even then it is better to spring for the extra money to get
the basement. Depending on the area where you live, a basement (usually) adds less than 5% to the total
cost of the house - sometimes less.
Nice to hear from you. Hope this helps. Get back to me if
you have more questions!
