Top 5 Mistakes People Make When Doing Drain Replacement (Redrain) in Houston

The 5 mistakes we see most often on Houston drain replacement (redrain) projects — and how to make sure they don't happen on yours.

Most drain replacement (redrain) projects don't fail because a contractor made one dramatic error — they fail because small, cheap-looking decisions stack up.

These are the mistakes we see most often on Houston jobs, and the ones we vet every scope against before we start.

1. Patching instead of replacing

Spot repairs on failing cast iron just delay the inevitable and cost more overall.

2. No camera inspection

Without video documentation before and after, you cant verify the work.

3. Missing cleanouts

Skipping cleanouts saves nothing and costs everything on the next stoppage.

4. Bellies in the new line

Improper slope is why the old pipe failed. Repeating it wastes the entire project.

5. Cheap slab restoration

A bad concrete patch cracks immediately and telegraphs the work forever.

How to vet your contractor

Read your drain replacement (redrain) bid line by line and ask which of these mistakes are being avoided — in writing. A contractor who welcomes the question is the one you want; a contractor who deflects is the one to walk away from.

If you'd like a second set of eyes on a scope of work or an existing bid, we're happy to walk through it with you.
