When it’s time for pipe replacement services, asking the right questions helps you find a team that’s transparent, reliable, and experienced. At In-House Plumbing Company, we believe you deserve honest answers up front — because choosing the right contractor matters.
Here’s what you should ask before moving forward with an old cast iron pipe replacement:
1. Will the same company handle both excavation and plumbing?
Splitting the work between different crews or companies can create gaps in responsibility — especially when problems arise.
2. Are they a licensed plumbing contractor or just an excavation crew?
Plumbing work under a slab is serious. Hiring an unlicensed team puts your home and health at risk.
3. Do they carry BOTH general liability and workers’ compensation insurance?
Workers’ comp isn’t required in Texas, so many companies skip it — putting you at risk if someone gets hurt.
4. Will they provide a clear, written proposal and diagram?
If there’s no documentation of what’s included or excluded, you won’t know what you’re getting until something goes wrong.
5. What’s included in their pricing, and is there flexibility?
At In-House Plumbing, we include sprinkler repair, brick reinstatement, and a 5-year warranty by default — but offer opt-out discounts to reduce cost.
6. What’s their backfill process — and do they reuse your soil?
Mixing in chemicals or different soils can damage your foundation. We use only your original soil, hand-packed section by section.
7. Do they rely on sewer cameras to evaluate pipe integrity?
Cameras can’t see cracks, corrosion, or missing sections from the outside. Don’t trust your decision to camera footage alone.
8. Do they push trenchless pipe methods?
These often sound great but fail in real-world conditions. Most trenchless systems can’t guarantee proper slope, sealing, or durability.
9. Will they be reachable later — and actually show up if there’s a problem?
A warranty is only as good as the company behind it. Will they stand behind their work five years from now?
10. Are they upfront about inspections, permits, and local code requirements?
Every city in DFW requires permits. If they’re suggesting skipping them, that’s a red flag.
Choosing the right company isn’t just about cast iron pipe replacement cost — it’s about finding someone you can trust.
