Floor Refinishing in Dublin

Dublin Conditions That Affect Floor Refinishing

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. Cool, damp days in Dublin lengthen finish cure times compared with a hot, dry one — a scheduling factor rather than a quality one.

Seasonal Gaps in Dublin Floors, by the Numbers

Seasonal gaps between boards are a common reason people ask about refinishing, and Dublin's measured climate shows how much of that gapping is simply the wood moving with the seasons. Measured at Livermore Municipal Airport, then brought to 70°F, the air averages 36.3% relative humidity over the heating season and 52.9% over summer, which settles wood at roughly 7.1% and 9.7% moisture content. For a traditional 2¼-inch oak strip floor that is about 0.022 inch of seasonal shrinkage per board (about 1/45 inch); for 5-inch plank, about 0.049 inch. Gaps in that range that open in winter and close by summer should not be filled — filler packed into a winter gap gets crushed out, or pushes the boards toward cupping, once the wood takes its moisture back.

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 where refinishing pays off most: homes of that period often have original wood under carpet, and when the wear layer is intact, refinishing keeps a floor that cannot be bought new. We check thickness at a vent or a doorway before recommending it.
