Compare collection coverage
Partial collection
Ask which observed entry paths this scope covers and what remains outside it.
Perimeter collection
More coverage means more work area. It does not establish the cause of every leak.
Reconstruct what was actually installed
Collect the contract, plan, equipment models, installation photographs, warranty and service records. Mark which walls were treated, where drainage runs and where it ends. Separate promised outcomes from components installed. “Waterproofing” on an invoice is not a complete map.
Start a new observation record: first visible entry point, timing, affected area and what the pump or alarm does. Compare it with earlier symptoms rather than assuming the cause is unchanged. Do not remove sealed covers, disable pumps or enter standing water to investigate.
Separate the remaining questions
| Observation | Question for the assessor | What it does not prove |
|---|---|---|
| Water beyond the treated wall | Was this area included in the collection design? | That every existing component needs replacement |
| Wet floor while the pump runs | Does water reach the basin, and where does discharge go? | That audible operation establishes adequate performance |
| Damp wall above a drain | Was wall moisture included in the promised outcome? | That a floor drain treats all wall moisture |
| Water near a window | Was the window and exterior runoff route assessed? | That another drain is the necessary answer |

A partial-system example
Hypothetical example, not a local project: a rear-wall drain was installed for seepage at that wall. During a later storm, water appears by a side-wall window. Ask whether the new symptom lies inside the original scope, whether a window-related path is visible, and how the proposed additional work addresses that evidence.
A wider drainage system could be appropriate after assessment, but its larger scope is not evidence by itself. Likewise, a small patch is not automatically sufficient. The useful comparison is the explained water path and the outcome each proposal covers.
Before paying for a second system
Give the original installer the dated records and ask for its findings in writing. Read the actual warranty: covered components, exclusions, maintenance obligations, notification process and any transfer conditions. This website cannot determine coverage or resolve a dispute.
For a second assessment, share the same evidence and request a marked plan. Ask which existing components can remain, which must change, why, and what will be tested at completion. Identify responsibility for restoring finishes and resolving any excluded source.
Choose the assessment before the repair
If the concern includes movement, distortion or damaged structural elements, ask an appropriately qualified structural professional about an independent evaluation. If timing points to a supply or waste line, a plumbing assessment may be the more relevant first step.
For a Phoenixville property, confirm the responsible municipality before new excavation, discharge or electrical work. Prior work does not establish approval for a different scope.

Common questions
Does more water mean the drain was installed incorrectly?
Not necessarily. The source, collection coverage, outlet and original scope need assessment. A photograph or the amount of water alone cannot establish workmanship or fault.
Should I remove the existing system before a second opinion?
Preserve records and ask the assessor what access is needed. Do not dismantle equipment or conceal the evidence before the scope and safety of further work are established.
