CrawlSpaceGuide

Our Methodology

CrawlSpaceGuide publishes cost estimates, pricing ranges, and project guidance for crawl space encapsulation. This page explains exactly how we arrive at those numbers and how we generate revenue.

How We Source Pricing Data

Our cost estimates are derived from the following sources, aggregated and updated periodically:

  • Angi (formerly Angie's List) cost reports - published annually, covering contractor-reported project costs by region and scope
  • HomeAdvisor True Cost Guide - project cost data collected from verified homeowner reviews
  • Groundworks public pricing documentation - published estimates from the largest specialty foundation contractor in the US
  • RS Means labor cost data - industry-standard construction labor rates by market and trade
  • Contractor outreach - direct conversations with encapsulation contractors across the Southeast to validate ranges

We do not publish exact prices - we publish ranges. This is intentional: a single quote cannot account for access difficulty, local labor market variation, or specific site conditions. Our ranges represent the realistic spread of actual contractor bids for a given scope.

How the Cost Calculator Works

The calculator uses a component-based pricing model:

  • Each component (vapor barrier, dehumidifier, drainage matting, insulation, vent sealing) has a per-square-foot or flat-rate cost range based on the sources above
  • A state-level labor multiplier adjusts the baseline (Southeast US average = 1.0) based on regional labor cost indexes
  • An access difficulty multiplier adds 0–25% to labor costs based on crawl space clearance

The result is a low-to-high range, not a single number. The midpoint reflects the most typical contractor quote for that configuration in that market.

The calculator does not account for: mold remediation (quoted separately), structural repairs, sump pump installation (unless selected), or permit fees (typically $100–$500 where required).

How We Make Money

CrawlSpaceGuide generates revenue through:

  • Contractor lead referrals: When you submit a lead through our calculator, we route your project information to contractors or lead aggregators. We receive a referral fee when a match is made. This does not affect the cost you pay to the contractor.
  • Amazon affiliate commissions: When we link to products (dehumidifiers, vapor barriers, etc.) and you purchase through those links, we earn a small commission at no cost to you. We only link to products we believe are appropriate for the use case.
  • Display advertising: Once traffic thresholds are reached, we may display contextually relevant ads. These will be clearly labeled.

Our revenue model creates an incentive to generate leads. We manage this by maintaining editorial independence: our cost guides and comparisons represent our honest research, not contractor talking points. We will tell you when you don't need encapsulation.

What We Do Not Do

  • Fabricate cost data or expert quotes
  • Accept payment for favorable editorial coverage
  • Use fake reviews or inflated AggregateRating schema
  • Claim credentials we don't have (see author page)
