About HomeRemodelCalc
A Valkyron Labs application
What this site is
HomeRemodelCalc is a free library of material calculators for home projects: paint, tile, flooring, drywall, concrete, and landscaping. You enter measurements and get a quantity to buy. There is no account and no saved project.
The calculators exist because bag, can, and roll counts are easy to get wrong from a label alone. Each page shows the formula, a worked example, and the assumptions behind the number.
Who builds it
The site is built and maintained by Valkyron Labs. Editorial decisions — formulas, waste allowances, and page updates — are made by the HomeRemodelCalc team. We do not publish a personal byline.
Pages show a “last reviewed” date when the calculator content was last checked. The method behind the numbers is on the methodology page.
How it stays current
We update a calculator when the formula, the default units, or the explanation changes. Cited figures are checked against the source page and dated. If a number on a can or a bag disagrees with our default, the product label wins.
