Hardwood Flooring in Clarksburg

Clarksburg Conditions That Affect Solid Hardwood

Clarksburg sits at about 10 feet in Yolo County. The regional Sacramento Valley record shows summer air cycling widely within each day rather than staying uniformly dry. In the National Weather Service publication "Climate of Sacramento, California" (revised August 2010), average relative humidity at Sacramento is 78 percent at 4 AM against 30 percent at 4 PM in July, a swing of roughly 48 points inside the same day. Those are Sacramento readings taken about 11 miles from Clarksburg, not local measurements.

Measured Humidity and Solid Wood Movement in Clarksburg

Sacramento Executive Airport, 7 miles from Clarksburg and at about the same elevation, supplied the 79,703 hourly dewpoint readings, 2015 to 2025, behind these figures. Warm that winter air to 70°F without adding moisture and it settles at a median 37.7% relative humidity, with 23% of heating-season hours below the 30% floor NWFA sets for wood floors; the same air reaches 54.8% in summer. Solid hardwood follows those numbers: its equilibrium moisture content runs from about 7.4% in the heating season to 10% in summer, and on the Forest Products Laboratory's coefficients for American white oak that swing changes the width of a 5-inch plainsawn board by about 0.049 inch (about 1/20 inch) — against 0.025 inch for the same board quartersawn. That is inside the range solid wood is specified for, but without much margin, so in Clarksburg board width and cut get decided before species does.

Clarksburg Homes We Work In

ACS 2020-2024 five-year estimates count just 111 housing units in the Clarksburg CDP, of which 48.6% were built in 1939 or earlier and 23.4% between 1950 and 1959. No units in the sample were built after 2009. Because the universe is small, these shares carry wide margins of error, but they establish an overwhelmingly pre-1960 stock. Clarksburg's pre-1940 and 1950s stock is directly relevant here, because homes of that period frequently have a board or plywood subfloor that will hold a nail-down installation, and sometimes original wood still under the carpet. We check for both before quoting a full replacement — refinishing what's already there is often the better answer.
