Why Claremont homes are different
In Claremont, a window replacement can be a preservation question before it is anything
else. The city keeps a local register, the Claremont Register of Structures
of Historic or Architectural Merit, and a listed house needs a Certificate of Appropriateness
before its windows change. The ordinance speaks to our trade directly: replacing windows
and doors in the same materials, form and color counts as a minor alteration that staff can
approve. Change the material, the muntin pattern or the way a sash opens, and the project can
move up to the Architectural and Preservation Commission instead. On a register house we
measure and photograph what is there first, because the existing window is the reference the
city will judge against.
The age of the stock is why this comes up at all. Sixteen percent of Claremont’s homes were
built before 1950, more than twice La Verne’s share and far above Walnut’s or West Covina’s, and the city’s own design guidelines describe a
Historic Claremont of 1890s to 1940s houses, an Old Claremont built mostly from the 1920s to
the 1950s, and enclaves like Russian Village and Pilgrim Place that date to the 1920s. The
bulk of the city is still postwar: 44 percent of homes went up in the 1950s and 1960s. Even on
an unlisted ranch house, exterior changes in the single-family districts get a staff
architectural review, so a style change is never purely a homeowner’s call here.
Then there is the north end. When the city adopted CAL FIRE’s updated hazard map in July 2025,
3,188 acres were rated Very High, with the hot spots north of the 210 toward the foothills.
A house in the northern hills and a house near the Village can be the same age and need
different glass, so we check the parcel map before we write the order.
Finally, more than a third of Claremont’s homes are rented, in a city that is also home to
the seven Claremont Colleges. When the owner does not live in the house, we plan the visit
around a tenant’s schedule and scope for durability over a style refresh.
What a job costs in Claremont
We do not publish a price list, because matching the profile and color of original windows on a register-listed house near the Village and replacing a slider in a foothill home where the fire map sets the glass are not the same job. What moves a quote is laid out on our cost pages, and the measure at your house, which is free, is where the actual number comes from.
