Corona Window Replacement provides professional custom window installation in Corona, CA for residential and commercial properties across the Corona and Temescal Valley corridor. The custom work in Corona is mostly geometry at height. Two-story tract elevations here put raked glass under the gable, a round-top over the entry, and a tall fixed lite beside a stair, and none of those three have a model number.
A raked unit is defined by an angle and two unequal jamb heights. Get the angle wrong by a degree over a nine-foot run and the unit arrives with a visible wedge of filler at one end, which is a thing you will notice from the street for as long as you own the house.
So the order starts with a template rather than a tape. We record both jamb heights, the pitch taken off the actual framing instead of the roof plan, and the diagonals, and we confirm which face of the stucco the flange is landing on before anybody prices glass.
The permit paperwork is where custom shapes get awkward. Installing windows at a house or a business sits on the Building Division's list of permitted work, and the application wants a floor plan with the old and new sizes called out plus the energy compliance form. A shape has no catalog size to put in the proposed column, so we dimension it from the template.
Title 24 Part 6 governs the numbers, and the 2025 edition took effect on the first of January. The prescriptive targets are U-factor 0.30 and a solar heat gain coefficient of 0.23, with Section 150.2(b)1B easing a vertical-glass replacement of 75 square feet or less to 0.40 and 0.35 in this zone.
That area threshold matters on a gable wall more than anywhere else, because a stacked assembly of a raked unit over a fixed lite over a slider adds up faster than people expect. We total the glass for the whole job before writing a specification rather than after, and we leave the temporary labels on the units so the inspector can read them without taking our word for anything.
Enlarging is a separate decision. Changing the head height on a gable means a new header and a framing review, and in a two-story elevation it also means scaffold and stucco. Leaving the opening alone and filling it accurately is usually the better trade.
What custom really costs you is optionality. The deposit goes the moment the order releases, because nobody else can use a unit cut to your angle. There is no shelf stock behind it, so a damaged arrival or a failure years out is another build cycle, not a swap.
The honest recommendation: on the 1980s and 1990s tracts on the south side, the openings are overwhelmingly plain rectangles with square aluminum frames, and those take a stock retrofit at a fraction of the price. Reserve the custom order for the two shapes that genuinely are shapes, and spend the savings on the glass package.
Our insured and bonded team brings the right materials and equipment to every job — cerium oxide chemo-mechanical glass polishing, alkali-leached, silica-rich weathering layers, number-one-surface mineral bonding, silane-based hydrophobic glass sealers, room-side surface-four low-E coatings, roller-wave distortion in tempered lites — and backs the work with a written workmanship warranty. We serve Corona and nearby communities including Norco, Eastvale, Jurupa Valley, Riverside.

Materials, equipment and how we do custom window installation
The difference between custom window installation that lasts and custom window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with cerium oxide chemo-mechanical glass polishing, alkali-leached, silica-rich weathering layers, number-one-surface mineral bonding, silane-based hydrophobic glass sealers, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Corona job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the Corona and Temescal Valley corridor means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Corona Chooses Corona Window Replacement
- ✓We diagnose the glass before we price the window, so you learn whether you need a sealed unit, a polish or a full replacement before you have paid anyone a deposit.
- ✓We do cerium oxide restoration in house, which means we have no reason at all to talk you into replacing a pane that can be brought back for a fraction of the cost.
- ✓We walk the irrigation with your controller running, because the sprinkler head causing the damage is nearly always cheaper to move than the glass it is quietly destroying.
- ✓We quote restoration, re-glazing and replacement as separate lines, so the cheap option sits visibly on the same page as the expensive one rather than buried underneath it.
