Custom & Specialty Shape Windows in Sunnyvale, CA

Arches, half-rounds, trapezoids, and transoms. We template off your actual opening, because no two are the same.

What it is

There Is No Catalogue Size for These

Arches, half-rounds, octagons, trapezoids, transoms, and other non-rectangular openings built to a template.

Rectangular windows come in standard sizes. These do not. A radius that is a quarter inch out, or a rake angle a degree off, shows immediately once the unit is in the wall and there is no adjusting it afterwards.

So we take a physical template off the actual opening rather than trusting the old unit's dimensions, and the replacement is manufactured to that template. It is slower and it is the only way these come out right.

Openings That Need a Template

A fogged arch or half-round

The unit above a door or picture window has failed while the rectangular units below are still clear.

A raked trapezoid

The angled unit following a vaulted or post-and-beam roofline. Every one is a different angle.

An octagon or circle

Usually in a stairwell, a bath, or a gable end, and almost never a stock size.

Transoms over an entry

The units above the front door that no longer seal, often several in a row that must match.

An entryway assembly

Sidelights, transoms, and an arch that all have to line up visually with the door and each other.

A builder-original no longer made

The original manufacturer's line is discontinued, so a like-for-like swap is not available.

How We Do It

  1. Step one

    Template the opening physically

    Taken off the wall itself, not off the old unit, because the old unit may never have fitted properly.

  2. Step two

    Match the visual details

    Radius, rake angle, sightlines, and grille pattern matched to the surrounding windows so it does not read as a replacement.

  3. Step three

    Confirm glass and tempering

    Glass package chosen and any tempering requirement for the location confirmed before the order goes in.

  4. Step four

    Install, flash, trim to match

    Set, flashed, insulated, and trimmed to the existing detail, inside and out.

Eichler-Era Walls Need These More Than Most

Sunnyvale's Eichler-era and post-and-beam homes bring raked trapezoids and tall fixed clerestory glass that standard sizes cannot serve. Those openings need a template and a manufacturer willing to build to it, which is why lead time on a specialty unit runs longer than on a slider. We tell you the real timeline at quote rather than at order confirmation.

Physical templating

Taken off your opening, so the radius and rake are right the first time.

Sightlines matched

Frame width and grille pattern matched to the windows around it.

Honest lead times

Specialty units take longer to build and we tell you how long before you commit.

Specialty Shape Questions

Longer than a rectangular unit, typically six to ten weeks from template rather than three to five. Complex shapes and matched sets take the upper end.

Usually yes. Grille pattern, bar width, and profile can be specified so the new unit reads as part of the original set rather than an obvious swap.

Some shapes can, some cannot. Trapezoids and octagons can often be built as awnings or casements. True arches and half-rounds are almost always fixed, because there is no practical way to hang a curved sash.

Yes, and it is a common job when the arch has fogged but the units below are fine. We match the new arch to the existing frames so the assembly still looks deliberate.
