Quick answer
603 provides waterproofing inspections in Wilmington. The free visit documents the property, defines the proposed work and exclusions, and prices the address rather than a townwide assumption.
Wilmington evidence card
Name the geography correctly
The source row identifies Wilmington as a county subdivision in Middlesex County. That label keeps this page tied to the correct Census geography; it does not tell 603 what exists below grade at a particular Wilmington address.
Keep the housing year in context
The 2023 ACS reports 1978 as the townwide median year built. A median is not the construction date of the inspected home, so the Wilmington visit still needs permits, prior invoices, photographs, and visible alteration clues before 603 describes an assembly.
Separate occupied homes from ownership
ACS table B25003 counts 7,871 occupied units in Wilmington: 6,841 owner-occupied and 1,030 in the remaining occupied category. The published owner share is 87%. Those figures put permission and decision authority on the checklist without assigning either status to the customer.
Do not turn building mix into a diagnosis
ACS table B25024 counts 8,032 housing units, including 6,711 single-unit detached structures and 1,321 units in other structure categories. The detached share is 84%. No ACS count identifies seepage. It only prevents the estimate from assuming one basement footprint, one decision-maker, or one discharge route.
Use population only as place context
Table B01003 reports 23,195 residents for Wilmington. That number identifies municipal scale, not demand, crew availability, travel time, or the likely condition of one basement. Scheduling and serviceability still depend on the address and proposed work.
Leave the unused-unit arithmetic out of the house story
The fact pack records 8,032 total units and 7,871 occupied units, a difference of 161. That difference is a town statistic only. It cannot support a vacancy claim about the inspected building or change the waterproofing recommendation.
Build the Wilmington service worksheet
For waterproofing, 603 starts with a marked property plan rather than a townwide pattern. The field record needs the reported wet location, rain timing, wall or floor-edge entry, existing drainage, sump access, power, and a lawful exterior outlet. The estimate should identify what was observed, what remains concealed, what the homeowner reported, and what must be confirmed before installation.
How the Wilmington visit turns into a decision
Step 1: Water reaches the floor edge
Trace where it appears, whether it follows rain, and where an interior drain can discharge. For Wilmington, the nearby municipal reference is 1,978 townwide median year built; it remains context and is not treated as a finding at the home. The inspector records the answer as observed, homeowner-reported, or still unknown, then marks its position on the property plan.
Step 2: The wall feels damp
Separate bulk water from condensation before choosing drainage or humidity control. For Wilmington, the nearby municipal reference is 7,871 occupied housing units; it remains context and is not treated as a finding at the home. The inspector records the answer as observed, homeowner-reported, or still unknown, then marks its position on the property plan.
Step 3: A sump runs often
Check the basin, pump, power, discharge route, and whether the drainage system reaches it. For Wilmington, the nearby municipal reference is 6,841 owner-occupied units; it remains context and is not treated as a finding at the home. The inspector records the answer as observed, homeowner-reported, or still unknown, then marks its position on the property plan.
Step 4: The basement smells musty
Measure humidity and inspect materials before assuming the odor proves an active leak. For Wilmington, the nearby municipal reference is 8,032 total housing units; it remains context and is not treated as a finding at the home. The inspector records the answer as observed, homeowner-reported, or still unknown, then marks its position on the property plan.
What the Wilmington proposal records
The final document connects the observed condition to preparation, measured quantities, the installation route, restoration, future service access, and the stated warranty. It also identifies owner responsibilities, third-party work, concealed unknowns, and the exact point where the approved waterproofing boundary stops. That lets the homeowner compare the proposed work rather than only the number at the bottom.
Prepare for the Wilmington inspection
Before 603 arrives, keep the reported area and the route to it visible. Gather dated photographs, earlier estimates, invoices, permits, equipment labels, and any test results that belong to this property. Write down when the concern appears, what changed beforehand, and whether another room provides a normal comparison. If the home has an addition or earlier lower-level work, identify that boundary on any available plan. The 1978 town median and 23,195-person Census count remain background only; the homeowner records establish the timeline for this address. Also identify who can approve the work and which utilities, stored items, pets, parking limits, or shared spaces could affect crew access. Those details help 603 price the intended waterproofing work without hiding preparation or restoration inside a broad allowance.

Price and written protection
603 currently places waterproofing projects in a broad $3,000 to $30,000 planning range. The measured quantities, access, preparation, equipment, and restoration determine the actual Wilmington price.
For qualifying work, 603 states a transferable lifetime warranty on a complete qualifying Forever Dry System. The proposal identifies the covered work, conditions, and exclusions.

Wilmington homeowner questions
Can wall panels hide an active leak?
Wall treatment belongs after the entry path is understood. The inspection should record what remains visible and what the system is designed to control.
Does an existing sump reduce the price?
Only if its basin, pump, power, discharge, and connection to the proposed drainage can remain in the finished design.
Does every wet basement need a full system?
No. The inspection should locate the entry path and define the smallest complete scope that controls it.
