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