PoolResurfacingCostCalculator.com is published by Jan Friederichs. I built it because pool resurfacing is one of the few five-figure home projects where almost nobody knows the going rate before the first contractor walks the deck.

Most “average cost” pages give one national number. That number is close to useless: the same 16′×32′ pool, same pebble finish, runs roughly twice as much in Hawaii as in Mississippi. So this site models the cost by state, shows the range rather than a single figure, and publishes the assumptions so you can argue with them.

Nothing here is gated. The full 50-state dataset is available as a CSV under a CC BY 4.0 license.

How the numbers are calculated

The reference project is a standard inground pool of roughly 500 sq ft of surface area — a 16′×32′ pool — in sound structural condition, resurfaced with a mid-range finish.

Each state’s modeled range combines four inputs:

The output for each state is a low estimate, a high estimate, and their midpoint. National figures are the plain average across all 50 states: $5,836 on the low end and $15,128 on the high end. A “+” on a published range means premium and custom projects routinely run past the stated high.

These are modeled estimates, not a survey of paid invoices. They are directional guidance for comparing states and for sanity-checking a quote — not a bid. Actual pricing moves with pool condition, finish choice, deck access, and local permitting. Always collect at least three quotes.

Update cadence

State figures and material costs are reviewed twice a year, in January and July, and any time a material or labor shift is large enough to move a state’s range by more than $500. Every page carries a visible “Last updated” line, and the machine-readable dateModified in each page’s structured data matches it.

Corrections and reuse

If a number here disagrees with a real quote you received, I want to hear about it — that is the only way the model improves. Send it over.
