About InsiderCost

Cost research, not contractor advertising.

We pull cost ranges from contractor surveys, manufacturer specs, IRS tax tables, and trade-association data — then translate them into ranges and decision frameworks U.S. homeowners can actually use.

InsiderCost publishes informational cost guides for U.S. homeowners researching home services projects: HVAC, plumbing, roofing, energy upgrades, remodeling, restoration, and security.

What we do

We pull cost ranges from primary sources — contractor surveys, manufacturer specs, IRS tax credit tables, EPA/OSHA regulations, and industry trade associations (NRCA, ACCA, IICRC, MPI, ASTM). We translate that into homeowner-friendly cost ranges with the variables that drive them.

Every cost figure on InsiderCost includes:

  • 2026 U.S. national average (refreshed annually)
  • The range that 80% of homeowners actually pay
  • What pushes a quote to the high end vs. the low end
  • Regional adjustment notes (Northeast vs. Southwest vs. Midwest)
  • Material-grade and contractor-experience variables

What we don’t do

  • We don’t write paid product reviews
  • We don’t promote contractors in exchange for placement fees
  • We don’t quote-shop for individual homeowners (we point you at industry lead-gen networks for that)
  • We don’t provide professional engineering, construction, plumbing, electrical, HVAC, or environmental remediation advice — only cost research and decision frameworks

How we make money

Affiliate links to retailers (Amazon, Home Depot, Lowe’s product pages) and lead-generation referrals to vetted contractor networks (Modernize, CraftJack, Networx, Angi). When you click those links and complete a purchase or quote request, InsiderCost may earn a referral fee at no extra cost to you. These relationships never change a cost figure or recommendation.

Editorial methodology

Cost research goes through this pipeline before publication:

  1. Data collection — pull pricing from at least 3 primary sources (contractor surveys, manufacturer MSRP, public bid databases, RSMeans construction data, BLS labor statistics)
  2. Triangulation — cross-check ranges against published guides from Modernize, HomeAdvisor, Bob Vila, Forbes Home (used as reference, not primary citation)
  3. Variable mapping — identify the 5-10 specific factors that explain the cost spread for that project type
  4. Editorial review — confirm citations, verify regulatory references for YMYL topics (asbestos, lead, biohazard, mold, radon)
  5. Publication — every guide includes a “Sources” section with primary source citations

Limitations

Cost ranges are starting points for research. Actual quotes depend on your geography, project specifics, contractor pricing, and conditions discovered during work. Always obtain three written quotes from licensed contractors before signing.

Reviewing cost data with regional breakdown

Every cost figure ships with a 2026 U.S. national average, the range 80% of homeowners actually pay, regional adjustments, and the variables that move a quote up or down.

Our Principles

Independent

No paid product reviews, no contractor placement fees, no editorial-for-hire. Affiliate links never change a number.

Primary sources

Manufacturer specs, contractor surveys, IRS credit tables, EPA/OSHA regulations, NRCA/ACCA/IICRC guidance. Reference guides are cross-checks, not citations.

Reader first

We don't quote-shop for individuals or sell your data. We point at vetted lead-gen networks and let you talk to contractors yourself.

Transparent

Every figure shows the year, the source, the range, and the variables that drive it. Corrections published within one week of any reader-spotted error.

What this isn't

Cost ranges are starting points for research, not professional engineering, plumbing, electrical, HVAC, or environmental remediation advice. Always obtain three written quotes from licensed contractors before signing, and rely on local pros for any decision that affects safety or compliance.
