HavenCostGuide

About

Honest renovation cost data — without the contractor markup.

HavenCostGuide exists because most homeowners walk into renovation projects blind. Contractors quote whatever the local market will bear, and online calculators are usually built to capture leads — not give you real numbers.

Published by RudderBay, a sole proprietorship. We operate under an institutional editorial byline (HavenCostGuide Editorial Team) — see our Editorial Standards for sourcing, fact-checking, and corrections policy.

Built from public data

We aggregate U.S. Bureau of Labor Statistics labor rates, publicly published contractor pricing, and industry benchmark reports (Remodeling Magazine Cost vs. Value, HomeAdvisor True Cost Guides, etc.) to build baseline ranges for each project type and size.

Updated twice yearly

Material costs and labor rates shift constantly. We refresh our baseline cost data every 6 months — once each spring and once each fall — and adjust regional multipliers based on the latest cost-of-living indices.

No spam, no upsell

We never sell your information. When you request quotes from local contractors, your details are shared only with vetted pros in your area — and only the ones you choose to engage.

Budget guidance, not bids

Estimates are typical ranges, not binding quotes. Site conditions, demo requirements, and structural surprises can move the actual cost outside our range. Always obtain 3+ written bids from licensed local contractors.

How we calculate

  1. 1Baseline range. Each project type has a low/high baseline range in dollars, set from national contractor pricing data and benchmark reports.
  2. 2State adjustment. California and New York add 40% (high cost), Texas and Florida sit at the national base, and most Midwest states subtract 15%.
  3. 3Quality multiplier. Budget grade is the baseline (×1.0), mid-range adds 30% (×1.3), and high-end premium materials run roughly 2.2× the baseline.
  4. 4Cost split. Labor (50%), materials (35%), and permits/fees (5%) — plus a 10% contingency on top to account for surprises.

Disclaimer: Estimates provided by HavenCostGuide are for budgeting purposes only. They are not professional bids and do not account for site-specific conditions, permits, structural issues, or material availability. Always consult licensed local contractors for binding quotes.

Editorial team

Who writes and reviews HavenCostGuide

Every cost calculator and every state-level guide on the site is researched, written, fact-checked, and reviewed by the HavenCostGuide Editorial Team. We publish under an institutional byline rather than individual author profiles — trust signals come from our sourcing, fact-checking process, and corrections record (all documented on our Editorial Standards page).
