Estimator Worked Example
One run of the Crawl Space Encapsulation Pros estimator, line by line: the inputs, each published range, and the total.
Worked example: the estimator with these inputs: 1200 sq ft of crawl space floor; Access / headroom (est. multiplier): Normal (3 ft+); Region cost level (est. multiplier): Average US; items: Vapor barrier installed, floor and walls ($2–$4/sq ft, HomeGuide), Seal vents and holes (HomeGuide), Crawl space dehumidifier, installed (HomeGuide). Each line is the published range times the quantity where it applies, times the multipliers, rounded to the nearest $10.
| Line item | Range |
|---|---|
| Vapor barrier installed, floor and walls ($2–$4/sq ft, HomeGuide) | $2,400 – $4,800 |
| Seal vents and holes (HomeGuide) | $150 – $450 |
| Crawl space dehumidifier, installed (HomeGuide) | $1,000 – $3,000 |
| Estimated total | $3,550 – $8,250 |
Your own numbers will differ. Run the estimator with your inputs, and see the methodology for where each range comes from. Guides: Crawl Space Encapsulation Cost Breakdown, Vapor Barrier vs. Full Encapsulation, Crawl Space Contractor Hiring Checklist.
