Windows
VertX installs dual-pane, low-E vinyl replacement windows and sliding patio doors for homes in the San Gabriel Valley and across Southern California, retrofit or full-frame depending on the opening. New windows seal the envelope, quiet the street, and shrink the load your solar and AC have to carry.
Solar makes your power, the battery stores it, HVAC spends it, and windows decide how much of it leaks out. In the SGV's summer heat, old single-pane windows force your AC to fight the outdoors all day. Sealing the envelope is how the whole system gets smaller, cheaper, and quieter.
Most whole-home window projects finish in one to three days. Manufacturer warranties on glass and frames, our workmanship warranty on the installation.
Where we do this
Each city has its own page: the utility, the permit path, fire-zone status, and the kind of homes we see there.
Common questions
In an older SGV home with single-pane aluminum windows, a lot. They are often the single biggest envelope leak. Dual-pane low-E replacements cut heat gain in summer, noise year-round, and the load your AC (and solar) has to cover.
Retrofit (insert) installation works well when frames are sound and is less invasive. Full-frame replacement is right when frames are damaged or you want to change sizes. We recommend per-opening, not one-size-fits-all.
Energy-rated windows periodically qualify for federal and state programs. We flag what applies at quote time.
In most San Gabriel Valley cities, yes, even for a like-for-like replacement, and California's energy code sets a minimum efficiency rating the new windows have to meet. We pull the permit and install windows that meet code.
A very thin metallic coating on the glass that reflects heat while letting light through. In our climate it is what keeps summer heat out. Combined with dual panes and an insulated frame, it is most of the difference between old aluminum sliders and a modern window.
Most whole-home replacements are installed in one to three days once the windows arrive. The wait before that is the order lead time, usually a few weeks, because they are built to measure for each opening.
Yes, noticeably. Dual-pane glass with an air gap blocks a lot more sound than a single pane, and a proper install seals the gaps around the frame where noise and heat both get through. Homes near a freeway or a busy street feel the difference the first night.
