Plumbing survey before purchase or renovation in Paris: lead pipes, cast iron, quick estimate

You're about to sign. The apartment is well located, the price is correct. But no one has told you what condition the plumbing is in.
In a Haussmann building or a pre-1970 construction, lead or cast iron pipes are common. Undetected before purchase, they can represent 5,000 to 20,000 EUR of unbudgeted work. And mandatory compliance work before any rental.
Reseau Tubulure carries out plumbing surveys before purchase or renovation, with a clear report and an honest estimate.
What investors and developers discover too late
Lead pipes have been banned since 1995 but are still very present in Parisian buildings predating that date. Their replacement is mandatory before any rental.
Aging cast iron columns may require complete replacement. In a 6-storey building, a damaged column can block the entire project and blow the budget.
Non-compliant connections create long-term risks. Successive bodges, non-standard connections, poorly placed drains - all problems an experienced plumber identifies immediately.
What our plumbing survey includes
During the visit, we check
- Pipe material (lead, copper, PVC, PER, cast iron)
- Condition of accessible risers and drainage columns
- Compliance of connections and water points
- Water pressure and meter condition
- Water heater or hot water tank condition
- Presence of active leaks or chronic moisture traces
What you receive
- A written report with photos. Clear description of each element inspected.
- An estimate of necessary work. Cost per item: pipes, compliance, urgent repairs.
- An expert opinion. We tell you clearly what's urgent, what can wait, and what can be negotiated in the sale price.
