Frequently asked questions
Does a sewer smell always mean a broken line?
No. A smell can have several causes, including a leak or a ventilation issue, so a provider needs to inspect before explaining what is happening.
What if the smell is only in the yard?
Note where it is strongest and whether drains are also slow or gurgling, then ask the provider what inspection is needed.
Should I use drain products before calling?
Limit water use if drains are backing up, avoid sewage contact, and ask the provider what to do next rather than trying work yourself.
Will Sewer Line Repair do the repair itself?
No. Sewer Line Repair is a referral service, not a plumbing provider. Callers are connected with independent local providers, and licensing, insurance and pricing should be confirmed directly with the provider before work begins.
