Repairs would include the following - I would be adding another bathroom (most likely in the basement) which will include framing, electrical, pluming, etc.

I agree with @Kenneth Garrett If you are adding pluming, or appliances to the kitchenette you will almost certainly need a permit if you want to avoid any possible issues in the future.

Years ago, I called a pluming company to resolve a recurring problem.

I have no experience but I am a good handy man I can do all minor/major repairs myself with pluming as the only exeption.

But if you were to replace it, I would make sure to use that time to insulate the house and take care of old pluming and possibly electical wires since it is probably a system lacking a ground wire being 1950's built, When I visited my sister in Florida, I noticed most of the houses built in her area (New Smirna Beach) are cinder block construction.

No evidence of ground water or bedrock, but the plume is bigger than first thought.

Check with a good Inspector, either privet or city to get a opinion of codes like Electrical, Pluming, Sewage, fire, Etc...

I had worked in construction as a helper for a guy who do pluming, tiles, kitchen, roofing,Sheetrocks.

Remediation company was if water is leaking you will have to call a plumber as we donot do pluming...
