How to Use This Calculator
  1. Enter the linear footage of the structure foundation perimeter.
  2. Select the treatment method: liquid barrier, baiting system, or combination.
  3. Input the local cost per linear foot for each method.
  4. Review the Estimated Treatment Cost and the Annual Renewal or Monitoring Fee.
  5. Compare the 10-Year Total Cost of each method to select the most economical long-term option.

How the result changes with Foundation perimeter (ft)

Foundation perimeter (ft)Total barrier cost ($)Cost per linear ft ($)
518$9,112.96$17.59
1,763$31,015.74$17.59

What each input means

Foundation perimeter (ft)
Total linear feet of foundation requiring barrier treatment.
Barrier type (0=Chemical, 1=Physical, 2=Combined)
0 = Liquid termiticide. 1 = Physical (stainless mesh/granite). 2 = Both combined.
Trench depth (ft)
Depth of treatment trench. 4 ft is standard for reaching footer depth.
Trench width (inches)
Width of treatment trench adjacent to foundation.
Stage (0=New construction, 1=Existing)
New construction is easier/cheaper. Existing requires working around landscaping and concrete.
Access difficulty (1=Easy, 2=Moderate, 3=Difficult)
1 = Open access. 2 = Some obstacles. 3 = Tight spaces, heavy landscaping.

What each result means

Total barrier cost ($)
Complete installed cost for the termite barrier system.
Cost per linear ft ($)
Total cost divided by perimeter length.
Chemical material ($)
Cost of liquid termiticide solution.
Physical barrier material ($)
Cost of stainless mesh or granite particle barrier.
Labor cost ($)
Trenching, installation, and backfill labor.
Drill & treat cost ($)
Cost for drilling through concrete (existing structures only).
Termiticide solution (gal)
Total gallons of diluted termiticide needed.
Trench volume (ft³)
Total volume of trench excavation.
Typical warranty (years)
Expected warranty period by barrier type.
Annualized cost ($)
Total cost spread over warranty period.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Foundation perimeter (ft) = 200, Barrier type (0=Chemical, 1=Physical, 2=Combined) = 0, Trench depth (ft) = 4, Trench width (inches) = 6 = 6 input(s) provided
  2. Calculate Total barrier cost
    Total barrier cost = totalMaterialCost + totalLaborCost + drillTreatCost
    3518.52 = $3,518.52
  3. Calculate Cost per linear ft
    Cost per linear ft = totalCost / perimeterFt
    17.59 = $17.59
  4. Calculate Chemical material
    800 = $800
  5. Calculate Physical barrier material
    0 = $0
