ES Windows Home Additions & ADU: The Long Beach Owner’s Guide
If you’re planning a home addition or ADU in Long Beach with ES Windows already specified or installed, the typical project runs $45,000 to $130,000 depending on square footage, foundation work, and how many window and door openings you’re tying into the existing structure. We stock and install ES Windows-compatible framing packages, flashing kits, and trim systems for additions and ADUs, and we can usually match your existing ES Windows style within a few days of your free estimate. Most Long Beach homeowners discover a problem when a new addition’s rough openings don’t line up with the ES Windows frame specs, or when an older ES Windows unit starts leaking at the sill after a room addition shifts the roofline. Either way, you need someone who knows the product, not someone learning on your wall.
Key Takeaways:
- Home additions and ADUs in Long Beach run $45,000 – $130,000 installed, and ES Windows compatibility is often the make-or-break detail.
- We’re an independent contractor, not affiliated with ES Windows, but we work with their frames, flashing, and trim daily.
- Written pricing before any work starts, background-checked crew, and a 365-Day Done Right Promise on the whole project.
- Call (562) 512-6480 for a free estimate and a written line-item price the same week you call.
Which ES Windows Models This Applies To
ES Windows are common in Long Beach mid-century homes and newer coastal builds, and for additions and ADUs the frame depth and sill profile are what matter most. We regularly match ES Windows series with 4-9/16″ to 7-1/2″ frame depths, but here’s the thing: the rough opening on an addition doesn’t care what the old house used. If the new wall is 2×6 and the existing ES Windows frames are 4-9/16″, you’ll need a jamb extension or a different series, and that decision has to be made before drywall goes up, not after. We measure every opening against the window label and the wall assembly, not just the glass size.
For OEM versus aftermarket, the honest answer depends on what failed. ES Windows extruded aluminum frames are specific, so for sill pans, corner keys, and fastening clips we prefer OEM. For weatherstripping, balance shoes, and glazing beads, quality aftermarket equivalents are usually fine and cost 30 – 50% less. Luca Romano has been doing this long enough to know which parts are worth the OEM price and which ones aren’t, and we’ll tell you before anything gets ordered.

Signs Your ES Windows Home Additions & ADU Is Failing
- Water staining at the bottom corners of the window or sliding door. This usually means the sill pan flashing wasn’t tied into the addition’s weather barrier, or an old seal has given out after the structure settled. Long Beach’s morning marine layer keeps moisture present enough that leaks don’t dry out on their own.
- The window binds when you open it, or the door to the new room rubs at the top corner. That’s often a framing issue, not a window issue. Additions settle differently than the original structure, and ES Windows aluminum frames are less forgiving of a racked rough opening than vinyl.
- Condensation between the panes or visible white film on the glass edge. Insulated glass unit seal failure. In Long Beach’s salt air, this shows up faster than inland, and once the seal is gone the fix is glass replacement, not a repair.
- You can feel air moving around the frame on windy days, or hear the ocean more than you used to. Weatherstripping has compressed or the frame has pulled away from the opening. It’s not just comfort, it’s your cooling bill.
- Hardware feels loose, or a slider jumps the track. Roller assemblies on ES Windows sliders wear after 10 – 15 years of sand and salt exposure, and replacement is straightforward if you have the right roller and the right adjusting tool.

AfterReplacement Cost & What’s Included
For a home addition or ADU in Long Beach with ES Windows integration, you’re looking at $45,000 to $130,000 all-in, and that’s not a wild swing, it’s driven by real variables. A simple 400-square-foot bump-out with two or three new ES Windows openings lands at the low end. A full detached ADU with a kitchenette, bath, and five-plus windows lands at the high end. Foundation type (slab vs raised), seismic shear-wall requirements in Long Beach, and whether we’re matching existing ES Windows or installing new all move the number.
Your written price includes rough and finish carpentry, ES Windows-compatible flashing and sill systems, installation of window and door units, trim, and the 365-Day Done Right Promise. If something isn’t done right in the first year, we fix it. No change orders, no surprise line items. The number you approve is the number you pay.
DIY or Call Us?
There are a few things you can check yourself. If a window binds, open it and look at the gap between the sash and frame, top to bottom. If it’s even, the window is probably fine and the issue is the wall. If it’s uneven, the frame is racked and that’s a structural concern. You can also inspect caulk joints and look for daylight around the frame. But taking an ES Windows unit out of an opening is not a Saturday project. Aluminum frames are heavy, glass breaks, and once you break the weather barrier, you’ve opened the envelope of the house to Long Beach’s salt air and whatever rain comes next. If the sill pan was done wrong on the addition and you don’t catch it, you’re looking at dry rot inside the wall within a couple of years. That’s a five-figure repair you don’t want.
If you’re planning an addition or ADU and ES Windows are part of the job, or you have an existing ES Windows unit that’s failing, call (562) 512-6480 and we’ll come out, measure, and give you a written price before any work starts. Luca’s crew doesn’t do vague, and we don’t do surprise invoices. The work tells you everything. The rest is just talking.
FAQs
You can expect 20 – 30 years from the frames themselves, but insulated glass seals and weatherstripping usually need attention around year 12 – 15, especially within a few miles of the coast where salt air accelerates seal failure. We inspect every existing unit before we build around it so you’re not putting a new addition on top of windows that are already halfway to replacement. Call (562) 512-6480 for an honest assessment, not a sales pitch.
Yes, in most cases. If the frame is sound, we can replace glass units, weatherstripping, rollers, and hardware without pulling the whole window. We also stock parts on the truck for KraftMaid, Cambria, and Silestone projects, so most hardware swaps happen in one visit. But if the frame is cracked, badly corroded, or racked from settlement, replacement is the honest call. Call (562) 512-6480 and we’ll tell you which direction makes sense for your budget.
A smaller room addition typically runs 8 – 12 weeks once permits are approved, and a detached ADU runs 4 – 6 months. Window rough-in and flashing happen early, so if your ES Windows are ordered and ready to install, that part of the job only takes a few days. We keep you updated with photos and written notes through the whole build, so you always know what happened on your job site that week. Call (562) 512-6480 to talk about your timeline.
We stock common weatherstripping, rollers, and hardware that fit ES Windows series, and for OEM-specific parts we order directly and install when they land, usually within a week. If you’re mid-project and a part failed, we can typically match it and keep you moving. Call (562) 512-6480 and describe what you’re looking at; we’ll tell you if we have it on the truck or if it needs to be ordered.
