Does New Siding Add Value in California?
We do not publish a resale value for this project yet. We have not found California sales data that measures it and that we are allowed to use, and we do not fill gaps with guesses. Value figures are coming in 2027 from our own analysis of public sales and permit records and a survey of California agents and appraisers.
Our likely cost runs from $21,300 in Fresno to $25,100 in San Francisco for the same job.
Not an appraisal, a broker price opinion or a prediction of a sale price. Costs are budget estimates, not a bid, appraisal, or insurance claim valuation. Pilot.
The project we priced
Siding replacement (fiber cement). 1,600 sq ft of fiber cement siding, old siding removed.
Same scope in every city, mid-range finishes. Your own home, size and finish choices will differ.

Likely is the median of 4,000 simulated outcomes from our estimator; the range is the 10th to 90th percentile. Share of median home value compares the likely cost with the city's median owner-occupied home value (U.S. Census Bureau, ACS 2025 1-year, table B25077).
Resale value: what we can verify
Value figures for this project are coming. Here is how we will get them, without borrowing anyone else's survey numbers:
- Public sales and permit records: compare homes that sold after a permitted project with similar homes that did not, county by county.
- A 2027 Caissonix survey of California real estate agents and appraisers, by region.
Until then, this page shows cost only. How we measure value.

Is this an appraisal?
No. It is an informational report: budget cost estimates plus the resale value evidence we can verify from public records and published studies. It is not an appraisal, a broker price opinion or a prediction of what your home will sell for. For a valuation, ask a licensed appraiser or a local real estate professional.
