What we do and what we do not
Be clear on the limits first. We are plumbers. We handle sump and ejector pumps, drain tile connections that lead to a pump, floor drains, supply leaks, sewer backups, and condensation and appliance sources. Structural waterproofing, such as exterior membranes, wall crack injection or regrading, belongs to a waterproofing or foundation contractor.
This saves you a wrong first call. Many damp basements turn out to be a plumbing source, and those are quick wins. Others need a different trade, and we say so.
| Water source | Plumbing work | Other trade |
|---|---|---|
| Sump pit not draining | Yes | No |
| Floor drain backing up | Yes | No |
| Supply pipe weeping in a wall | Yes | Drywall repair |
| Water at the wall after heavy rain | Pump and drain check | Exterior grading or membrane |
| Foundation crack | No | Foundation contractor |
| Appliance or water heater leak | Yes | Flooring repair |
If you are unsure, call. A short description helps sort it out.
Plumbing causes of a damp basement
- Wet floor near the water heaterA tank leak or a failed relief valve.
- Puddle under a washer or sinkA hose or drain line leaking slowly.
- Water at a floor drainA clog, a backup or a failed trap seal.
- Damp spot along a wall with pipesA weeping supply fitting.
- Sump pit full and pump silentA failed pump or switch.
- Sweating cold pipesCondensation from warm humid air, not a leak.
- Smell of sewageA cracked drain or a dry trap.
Standards behind sump work
Sump and effluent pumps are tested under UL 778 for motor-operated water pumps, and new discharge and drain connections fall under New Jersey's Uniform Construction Code plumbing subcode (N.J.A.C. 5:23-3.15). That is why a pump swap can be simple while rerouting a discharge line may need a permit.
Why damp basements and crawl spaces happen here
Manchester Township sits in the Pinelands, where soil is sandy and drains fast. That often keeps basements drier than clay soils would, but low spots near lakes and streams can see water in wet seasons. We cannot say the water table depth at your address, so look at what the water is doing.
The median home was built in 1979, and about half predate 1980. Houses of that age may have older pump pits, original floor drains, and supply lines near the end of their life. A basement that never had a pump may still have a plumbing leak behind it.
Crawl spaces add one more cause, which is moisture rising from the ground and condensing on cool pipes. If the dirt looks damp, check for a leaking line first, then ask about a vapor barrier from a crawl space contractor.
Active-adult homes with finished basements or laundry rooms are worth checking too, because a hidden appliance leak can go unnoticed there.
A five-minute check before you call
- Note when it happensAfter rain suggests ground water. Always wet suggests a pipe. After laundry suggests a drain or hose.
- Find the wet spotIs it near a wall, a drain, an appliance or a pipe?
- Check the meterWith all water off, a moving meter points to a supply leak.
- Test the pumpPour a bucket of water into the pit and watch it start.
- Look at the water heaterCheck around the base and the relief valve line.
Share what you find on the call. It helps a plumber arrive with the right tools.
Fixes we do, in order of likelihood
- Replace a bad hose, valve or drain line at a washer or sink.
- Repair a weeping supply pipe or fitting.
- Clear and test a floor drain, or fix its trap.
- Install or replace a sump pump and its check valve.
- Add a battery backup or alarm.
- Install an ejector pump for a below-grade bath or laundry.
If the source turns out to be a hidden supply line, see leak detection. If it is a backup, see sewer line repair. A leaking heater is covered under water heater repair.
What affects the cost
- Source of the waterA hose is simple. A buried drain or a pit rebuild is bigger.
- AccessFinished basement walls and slab work add time.
- EquipmentPump size, backup and alarm options change the total.
- Number of fixesMore than one source means more than one repair.
- Emergency timingAfter-hours dispatch is priced differently from a planned visit.

When the answer is another trade
If water enters through a crack, a window well or a foundation wall after rain, a waterproofing or foundation specialist is the right call. Exterior regrading, gutter extensions and downspout routing may solve it without any plumbing. We can tell you when the plumbing side is clean so you can look elsewhere with confidence.
We also dispatch to Jackson, Lakewood and Berkeley Township. We do not repair water damage or treat mold.

Frequently asked questions
No. We handle the plumbing side: pumps, floor drains, supply leaks and sewer backups. Cracks, exterior membranes and regrading belong to another trade.
Check the water meter with everything off. If it moves, a supply pipe is leaking. If the water appears only after rain, the source is more likely ground water.
If water collects in a pit and needs to leave, yes. A pump does not stop water from entering through cracks, which a different trade handles.
Cold pipes in warm humid air collect condensation. It looks like a leak but is not one. Insulating the pipes or lowering humidity usually helps.
Yes for plumbing emergencies such as a burst pipe, a failed pump or a sewer backup. The line is open 24/7 and same-day visits are offered when available.
Yes. It usually means a clog in the drain or the main line. Stop using water and call.
No. We repair the plumbing. Water removal, drying and mold treatment are separate trades.
