Hardwood Flooring in Dublin

Dublin Conditions That Affect Solid Hardwood

Dublin sits at about 360 feet in Alameda County. No humidity-recording station sits in Dublin. The nearest, Livermore Municipal Airport 4.7 miles east, averages 34.0% relative humidity at 4 PM and 79.2% at 4 AM across the ten Julys 2015-2024 — a gap of about 45 points between those two hours, against about 20 points at bay-side Oakland International Airport.

Dublin lies inland of the East Bay hills. No NOAA station in Dublin carries 1991-2020 normals; the nearest stations with normals record July average highs of 87.7°F at Livermore Municipal Airport to the east and 71.6°F at the Oakland Museum station on the bay side of the hills. Whatever the outdoor pattern in Dublin, solid hardwood responds to the air inside the house, so the wood acclimates to the rooms it is going into rather than to a delivery truck or a garage.

Measured Humidity and Solid Wood Movement in Dublin

Livermore Municipal Airport, 5 miles from Dublin 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 36.3% relative humidity, with 28% of heating-season hours below the 30% floor NWFA sets for wood floors; the same air reaches 52.9% in summer. Solid hardwood follows those numbers: its equilibrium moisture content runs from about 7.1% in the heating season to 9.7% 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 Dublin board width and cut get decided before species does.

Dublin Homes We Work In

ACS 2020-2024 five-year estimates count 25,157 housing units, of which 30.6% were built 2010-2019 and 26.9% built 2000-2009 — 60.0% of the stock dates to 2000 or later once the 2.5% built 2020 or later is included. This is the newest housing stock of any city in this service area. Only 0.5% predates 1940. A secondary 1960s cohort accounts for 13.4%. Dublin's 2000s and 2010s 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.
