Quick answer
603 provides radon mitigation inspections in Shrewsbury. The free visit documents the property, defines the proposed work and exclusions, and prices the address rather than a townwide assumption.
Shrewsbury evidence card
Name the geography correctly
The source row identifies Shrewsbury as a county subdivision in Worcester County. That label keeps this page tied to the correct Census geography; it does not tell 603 what exists below grade at a particular Shrewsbury address.
Keep the housing year in context
The 2023 ACS reports 1979 as the townwide median year built. A median is not the construction date of the inspected home, so the Shrewsbury 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 14,508 occupied units in Shrewsbury: 10,462 owner-occupied and 4,046 in the remaining occupied category. The published owner share is 72%. 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 15,318 housing units, including 10,072 single-unit detached structures and 5,246 units in other structure categories. The detached share is 66%. No ACS count predicts a radon result or pressure-field communication. Testing and field diagnostics remain address-specific.
Use population only as place context
Table B01003 reports 38,440 residents for Shrewsbury. 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 15,318 total units and 14,508 occupied units, a difference of 810. That difference is a town statistic only. It cannot support a vacancy claim about the inspected building or change the radon mitigation recommendation.
Build the Shrewsbury service worksheet
For radon mitigation, 603 starts with a marked property plan rather than a townwide pattern. The mitigation sketch needs the test location, each slab or crawl section, sump openings, candidate suction points, fan placement, power, and the exhaust route. The estimate should identify what was observed, what remains concealed, what the homeowner reported, and what must be confirmed before installation.
How the Shrewsbury visit turns into a decision
Step 1: A test came back elevated
Confirm the test conditions and inspect the slab, foundation, and possible suction locations. For Shrewsbury, the nearby municipal reference is 1,979 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 basement has several slabs
Map each footprint because one suction point may not communicate through every section. For Shrewsbury, the nearby municipal reference is 14,508 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 system already exists
Check the fan, monitor, piping, seals, and whether the current suction field still performs. For Shrewsbury, the nearby municipal reference is 10,462 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: Well water is part of the concern
Keep airborne radon and radon in water as separate measurements and separate treatment decisions. For Shrewsbury, the nearby municipal reference is 15,318 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 Shrewsbury 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 radon mitigation boundary stops. That lets the homeowner compare the proposed work rather than only the number at the bottom.
Prepare for the Shrewsbury 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 1979 town median and 38,440-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 radon mitigation work without hiding preparation or restoration inside a broad allowance.
A 603 radon mitigation work example
Price and written protection
603 currently places radon mitigation projects in a broad $900 to $6,000, with most systems between $1,950 and $2,250 planning range. The measured quantities, access, preparation, equipment, and restoration determine the actual Shrewsbury price.
For qualifying work, 603 states a 10-year warranty on the mitigation system and its components. The proposal identifies the covered work, conditions, and exclusions.

Shrewsbury homeowner questions
Does 603 guarantee a particular radon number?
No. The system is designed and installed to reduce radon, but a specific final reading is not guaranteed.
What does the system monitor show?
The monitor shows whether the fan is creating pressure in the pipe. It does not replace a radon test of the home.
Can one fan serve an addition and the original slab?
Only when field testing shows the suction field communicates across those footprints. The plan should not assume it.
