ES Windows Home Additions & ADU: The Orlando Owner’s Guide
If you’re planning a home addition or ADU in Orlando with ES Windows installed or specified, you need a contractor who understands how those window and door systems integrate into Florida framing, waterproofing, and code. A full home addition in Orlando runs $45,000 – $130,000, while an ADU typically lands between $90,000 and $220,000 depending on size, foundation work, and finish level. Most Orlando homeowners call us after realizing their existing ES Windows units won’t simply carry over into the new square footage, or after a builder told them the window rough openings need custom framing to match ES Windows’ exact jamb depths. That’s where we step in.
Here’s what we mean. ES Windows are engineered aluminum or vinyl-framed units with specific flange and fin configurations. When you add a room or build a detached ADU in Orlando, the new window and door schedule has to match or deliberately complement what’s already on the house. We handle that matching from the frame up.
Which ES Windows Models This Applies To
ES Windows produces a range of residential and light-commercial window lines, including single-hung, horizontal roller, casement, fixed picture, and sliding glass door units. The part-level compatibility challenge in home additions and ADU work is the frame profile. ES Windows aluminum and vinyl lines use different jamb depths, fin sets, and mullion systems depending on the series. If your existing home has ES Windows in an older Miami-Dade-rated aluminum profile and your addition calls for a newer vinyl series, the window-to-wall transitions won’t match unless we flash and trim them deliberately. That’s not a reason to rip out good windows. It’s a reason to have someone who actually reads the ES Windows product label before ordering.
How to identify your unit: look for a small etched or printed label on the glass near the corner, or a white sticker on the head of the frame. It will list a series code, the glass composition, and the DP (design pressure) rating. For Orlando additions, the DP rating matters because your new permit requires wind-load documentation. We photograph every label before any demolition starts.
OEM versus aftermarket: for ES Windows, the original glazing and hardware are worth sticking with when possible, especially on impact-rated units. Aftermarket replacement parts like weatherstripping, rollers, and lock sets are generally fine and often better-priced. The one place we don’t compromise is the glass unit itself. Mixing non-impact glazing into an impact-rated ES Windows frame in Orlando is a code violation and a safety mistake during hurricane season.

Signs Your ES Windows Home Addition or ADU Build is Heading Wrong
Additions and ADUs don’t “fail” like a broken spring, but the window and door integration can fail if the contractor isn’t paying attention. Here are the five things we get called to fix most often around Orlando, especially in College Park, Audubon Park, and Winter Park bungalow additions:
- The rough opening is oversized and shimmed with scrap. Some framers cut openings loose and pack the gaps. That leaves no room for proper flashing, and it’s exactly where Orlando’s afternoon thunderstorms find a path inside.
- The new windows were ordered without matching DP ratings. Your existing home may have DP50 units. If the addition gets DP35, you’ve created a weak wall that a wind-load inspection will flag.
- Water stains forming at the window corners within the first wet season. Florida gets sixty inches of rain a year. Bad sill flashing shows up fast. This is usually installation error, not the window.
- Doors and windows out of square in the new addition. When a slab moves or the framing wasn’t done to spec, the ES Windows sliding door binds on the track. It’s a structural signal, not a lubrication issue.
- No thermal break information, and the addition bakes. ES Windows’ aluminum lines without a proper thermal break transfer Orlando heat directly through the frame. The glass may be fine while the frame argues with your AC bill.
Each of these has a fix. The earlier you catch it, the less invasive that fix becomes.

What’s included in our number: every hour of labor, the ES Windows units or specified alternates, flashing, trim, permit coordination, and a written line-item price before any demolition starts. You’ll never get a change order because we “didn’t realize” the rough openings needed custom work. We know before we quote. Luca Romano walks every project before pricing it, and he’s been doing Central Florida additions and structural work for nearly two decades. The 365-Day Done Right Promise covers the work in writing: if it’s not done right, we make it right.

DIY or Call Us?
You can absolutely handle a few things before calling anyone: identify your window labels, measure existing rough openings, note the DP rating on a spreadsheet, and decide whether you want an attached addition or a detached ADU. That prep saves real time. What you shouldn’t DIY is cutting new openings in load-bearing walls, setting headers, or flashing windows against Florida rain. When a homeowner tries to save money by cutting a rough opening without an engineer’s signature, the lintel ends up undersized and the wall sags by the following spring. Good work doesn’t need a speech, it just needs to hold up. For everything structural, call (850) 809-0306.
FAQs
Plan on a 20 – 30 year service life for ES Windows aluminum or vinyl units in Orlando, with glazing seals sometimes softening around year 15 from constant heat and UV exposure. Coated aluminum frames hold up well; vinyl frames in full afternoon sun can warp slightly, which is why frame brand and orientation matter when we specify.
Sometimes, yes. If your windows are in good condition, we can re-frame and re-install them, but you’ll want to replace the flashing, weatherstripping, and possibly the glazing tape on any unit coming out and going back in. Saved units still need labor, and the savings compared to new impact-rated units is usually 30 – 50%. Call (850) 809-0306 and we’ll tell you honestly if reuse makes sense.
Most Orlando additions run 3 – 6 months from permit to final inspection; an ADU typically runs 4 – 8 months. Permitting timelines vary by municipality, and we keep you posted with before-and-after photo updates and a live arrival time at every stage.
We don’t warehouse glass, but we order ES Windows and equivalent units directly through established supply channels and verify every spec before the order goes in. That means your windows arrive once, correctly. We also support work around KraftMaid cabinetry, and Cambria or Silestone countertop lines in the same addition or ADU scope.
