Home Foundation with Hot Spots?? (house, floor, space, bedroom)

[eyewrist]

I went to a client's house and they asked me if I could feel the warm spots on the floor just to make sure they were not crazy. So I walked on the pergo floor and they were right! You can feel a temperature change as you walked from one spot to another. He said his entire bedroom florr was like that. I looked at the wall and ceiling and notice cracks so I told him maybe something wrong with the foundation. What could be the cause? The gas drilling or fracturing they are doing? Sewage problems? Anyone out there have any idea??? I'm curious.

Cast iron can transmitt heat pretty effectively and radiate it out pretty slowly, that'd be my first guess. Even heat from dumping water from clothes washer, dishwasher cycle or long hot shower could warm up pipe enough to feel through floor...

Sometimes the return line from an A/C compressor might have been run in the slab, those can be very warm...

Could also be issue with electrical lines in / under slab, but I would think that any long term drain would also be noted by other unsafe / expensive side effects.

I really doubt any sort of drilling / mining is going to have effects on normal surface slab.

Any chance there is an issue with a thermal spring? Old Faithful nearby? How about lava?

(really remote chance but would make for a good Steven King horror story...)

I guess he is going to find out. It a newer home (early 90s) so no cast iron. My fear is that a sewer line may be involved...let's hope not. He's wanting to sell it but I see a lot of preventive maintenance was not done throughout the years

Is it a concrete slab floor or is there a crawl space underneath? Or a basement?

Sorry, got very busy this week. It's slab no crawl space or basement.

I do not believe the problem to be a heat rise phenomena caused by failing electric or heated discharge. Such would have presented systemic issues elsewhere telling of a problem.

Instead, I believe its a heat loss issue making different parts of the floor colder thusly presenting a state of heat in other areas.

I came home to a hot spot, pergo-type kitchen floor, turns out the hot water line had ruptured. I suspect this has happened and it is migrating along a pipe line under the slab, heating it.
