Roots
Maple roots in clay laterals are the most common cause. They build up for months, then a big load of laundry or a holiday dinner finishes the job.

D-06EMERGENCY DISPATCH
A real dispatcher picks up at 2 a.m. on a Sunday, on Christmas Eve, during a February nor'easter. Same rate as a Tuesday morning. We'll give you an honest arrival time and tell you what to do until we get there.
Can't talk? Text a photo to (603) 555-0149 and we'll call you back.

Maple roots in clay laterals are the most common cause. They build up for months, then a big load of laundry or a holiday dinner finishes the job.
Especially in multi-family buildings where several households share one line.
In older parts of Manchester, the city sewer can surcharge during big storms or fast spring thaws. Water can push back up into basement floor drains even when your own line is fine. A backwater valve can help in these cases. Ask us whether your house is a candidate.
Less common, but they happen in deep cold or in old Orangeburg and clay.
It depends on the hour, the weather and how many calls are ahead of you. Dispatch gives you an honest arrival window when you call, not a guess meant to keep you on the line. If someone closer can reach you sooner, especially in the outer towns, we'll tell you that too.
It depends on your policy. Many standard policies exclude sewer backup unless you've added a specific endorsement or rider. Take photos before cleanup and call your insurer early. We can send your adjuster our camera footage and a written note on the cause, which often helps the claim.
Call us first if sewage is still coming up, because nothing else helps until the line is clear. If the line is already flowing and you have water on finished floors or walls, call a restoration company too. We often work in the same basement on the same night.
Usually, if you stay out of the affected area and stop using water. Leave right away if water is touching electrical equipment, if you smell gas, or if anyone feels sick. Sewage is a health risk, so keep children and pets away and wash up carefully after any contact.
