Frequently Asked Questions

Don't see your question here? Call us — we're happy to talk it through before you book anything.

Do you charge for estimates?
No. Every inspection, diagnosis, and quote for drain, waste, or vent work is done free of charge. We confirm what's actually causing a backup before we recommend a repair.
Why does my drain keep clogging even after it's been cleared?
A recurring clog is usually a symptom of a larger issue — a collapsed or root-damaged line, an improperly pitched section of pipe, or a vent that isn't sized or tied in correctly.
Do you install sump pumps and battery back-up systems?
Yes. We stock and install sump pump systems and basins, including emergency battery back-up units and water-driven backup systems that keep working even if your power goes out during a storm — which is exactly when you need them most.
Why does my house have vent piping, and what happens if it fails?
Vent piping keeps the water seals in your drain traps intact and lets waste lines drain properly. If a vent is undersized, blocked, or improperly tied in, you can get slow drains, gurgling, or sewer odor in the house even when nothing appears clogged.
