What the maintainer is responsible for
- Maintain visible calculator formulas for base fee, unit rate, scope, scheduling, and location assumptions.
- Review each guide for quote-comparison usefulness before publishing or updating.
- Check official consumer, safety, licensing, energy, tax, or permit references when they affect homeowner decisions.
- Review reader corrections and adjust pages when a formula assumption, source link, or quote-risk note is outdated or unclear.
Why the project exists
- Many home project cost pages hide the useful planning details behind lead forms or broad averages.
- 51828 is maintained as a practical calculator-first reference so homeowners can understand the scope before talking to contractors.
- The project focuses on transparent formulas, quote comparison, source links, and correction handling rather than contractor matching or paid rankings.
How data is handled
- Calculator values are treated as planning models, not guaranteed prices or scraped contractor bids.
- Official sources are used for consumer, safety, licensing, energy, tax, permit, and labor-market context, not as direct quote totals.
- Public market references are paraphrased into short benchmark notes and linked to the original pages.
- Reader-submitted quote examples should remove names, addresses, phone numbers, contractor identifiers, and other personal details before review.
- Corrections are checked against the visible model, source library, related pages, and the homeowner decision task before changes are published.
Expertise and limits
51828's credibility is based on visible assumptions, official context sources, practical quote-comparison structure, and a correction process. The site does not present its maintainer as a licensed contractor or professional adviser.
51828 is not a licensed contractor, engineering firm, law firm, insurer, tax adviser, or contractor marketplace. Local licensed professionals and written quotes should override online planning estimates.
Editorial independence
51828 does not sell contractor leads, does not rank contractors, and does not accept payment to change calculator formulas, red flags, quote worksheets, or editorial conclusions.
What to send
For corrections, include a page URL, location, project size, written quote line items if available, and whether the quote included permits, disposal, warranty, and cleanup. For privacy or business inquiries, include a clear subject line so the message can be routed correctly.
