Window in Claremont, CA
Claremont's college-adjacent blocks hold a serious concentration of Craftsman and Spanish Colonial Revival houses with original wood sash.
Claremont falls in Climate Zone 9 rather than 10, so the zone written on the certificate changes even though the two prescriptive limits happen to land in the same place.
About Claremont, CA — and why local matters here
Claremont sits in Los Angeles County with a population of roughly 37,266 at the 2020 census, in California Building Climate Zone 9, close enough to Fontana that crews move between the two constantly. Local landmarks and corridors residents know well include the Indian Hill Boulevard tree canopy, the College Avenue bungalow blocks.
Local knowledge is not a marketing line here. Claremont properties share soil, weather, permit rules and construction eras with the rest of Los Angeles County, and a window contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.

Window work we do in Claremont, CA
Fontana Window Replacement covers the same range of work in Claremont that we do in Fontana — nothing is carved out because the address is a few miles up the road:
- Title 24 Compliance & Energy Documentation — Every replacement opening in this city answers to one document before it answers to a salesperson. Fontana sits in California Building Climate Zone 10, and the prescriptive fenestration package for that zone is a maximum U-factor of 0.30 and a maximum solar heat gain coefficient of 0.23.
- Energy-Efficient & Low-E Glass Packages — In Climate Zone 10 the two prescriptive numbers are not equally hard. A 0.30 U-factor is routine for any decent dual-pane unit.
- Vinyl Windows — Vinyl is the frame that makes the Zone 10 numbers cheapest to reach. A multi-chamber welded vinyl frame with a decent coating clears a 0.30 U-factor without effort and leaves the whole compliance argument resting on the glass, which is where it belongs.
- Fiberglass & Composite Windows — Pultruded fiberglass earns its price here for a reason that rarely gets said out loud. It buys label headroom.
- Wood & Clad-Wood Windows — The trap with clad wood is not the product. It is the paperwork.
- Aluminum Windows — This is the page where the code and the sales pitch disagree. Non-thermally-broken aluminum cannot meet the Zone 10 prescriptive U-factor on a house.
