To unclog is to remove an obstruction from a passage such as a drain, gutter or pipe. Clearing the blockage does not necessarily repair its cause.
What this means at your property
A recurring backup may involve debris, damage, slope or another system condition. Once flow returns, the affected property may still need cleanup or drying, and repeated blockages can warrant further investigation.
What should be recorded after the blockage is cleared?
Ask what was found, which section was serviced and whether follow-up is recommended. Keep that record separate from the restoration scope so an apparently functioning drain does not obscure damage already caused by the overflow.
