How to Use This Calculator
  1. Enter the structure perimeter in linear feet and the number of penetrations (pipes, conduits, gaps).
  2. Set the pest target type: rodents, insects, or both.
  3. Input the average gap size found during inspection in inches.
  4. Review the Linear Feet of Exclusion Material Required and the number of penetration seals needed.
  5. Use the Labor Hours Estimate to prepare the exclusion quote for the customer.

What each input means

Building perimeter (ft)
Total exterior perimeter of the structure.
Number of stories
Building height. Multi-story adds 15% labor per floor for access equipment.
Foundation cracks to seal
Number of visible cracks in foundation walls needing caulk/backer rod.
Utility penetrations
Pipe, wire, and conduit entries through walls (each sealed with copper mesh + foam).
Weep holes to screen
Brick weep holes to fit with stainless steel mesh inserts.
Doors needing sweeps/seals
Exterior doors requiring new sweeps or threshold seals.

What each result means

Total exclusion points
Total number of entry points to be sealed.
Material cost ($)
Cost of caulk, copper mesh, foam, screens, sweeps, etc.
Labor cost ($)
Professional labor including access equipment.
Total exclusion cost ($)
Combined material and labor cost.
Cost per linear ft ($)
Total cost divided by building perimeter.
Estimated labor hours
Approximate technician hours for the job.
Crack sealing cost ($)
Cost for foundation crack repairs.
Utility penetration cost ($)
Cost to seal pipe and wire entries.
Door sealing cost ($)
Cost for door sweeps and threshold seals.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Building perimeter (ft) = 200, Number of stories = 1, Foundation cracks to seal = 5, Utility penetrations = 8 = 6 input(s) provided
  2. Calculate Total exclusion points
    Total exclusion points = foundationCracks + utilityPenetrations + weepHoles
    31 = 31
  3. Calculate Total exclusion cost
    Total exclusion cost = totalMaterial + totalLabor
    975 = $975
  4. Calculate Material cost
    Material cost = crackSealMaterial + utilPenMaterial + weepScreenMaterial
    349 = $349
  5. Calculate Labor cost
    Labor cost = (crackSealLabor + utilPenLabor + weepScreenLabor
    626 = $626
