ES Windows Home Additions & ADU: The Dallas Owner’s Guide
Adding square footage with ES Windows products in Dallas typically runs $45,000 – $130,000 for a home addition and $90,000 – $220,000 for a full ADU, depending on foundation work, window count, and finish level. We stock and install ES Windows-compatible glazing packages for additions and ADUs in Dallas, and most homeowners call us when their existing ES Windows units start showing condensation between panes, failed seals, or frames that no longer open smoothly in Dallas heat. Penhallow Remodeling Dallas is an independent service provider, not affiliated with ES Windows, but we know their product lines well enough to match parts and glass correctly the first time.
Which ES Windows Models This Applies To
ES Windows is a Florida-based manufacturer known for impact-rated aluminum and vinyl lines built for coastal and high-wind zones, which means their units often show up in Dallas additions where homeowners want serious thermal and structural performance. The most common lines we work with are the ES Windows 7000 Series (aluminum, impact-rated) and the 5000 Series (vinyl, thermally broken). You’ll find the model number etched on a metal tag inside the frame track, typically on the top or side jamb. The compatibility gotcha: ES Windows uses proprietary glazing beads and balance systems, so a generic aftermarket sash or balance from a local Dallas supplier often won’t seat properly. For ES Windows specifically, we recommend OEM glass and hardware for anything impact-rated; for non-impact 5000 Series units, a quality aftermarket balance or weather seal from a recognized supplier works fine. Bring us the tag number and a photo of the failed part, and we’ll tell you exactly what fits.

Signs Your ES Windows Home Additions & ADU Is Failing
- Condensation between the glass panes. This means the insulated glass unit seal has failed and the argon or krypton fill has escaped. In Dallas humidity, this shows up fast once the seal goes, and the fix is a new IGU, not a wipe-down.
- Windows that stick or won’t stay open. ES Windows balance systems wear out, especially on large sashes that get opened daily during Dallas springs and falls. If the window drops shut or needs two hands to lift, the balances are done.
- Drafts around the sash. Failing weatherstripping or a warped frame lets air in. You’ll notice it most on north-facing walls of Dallas-area ADUs that catch winter wind.
- Visible corrosion or pitting on aluminum frames. Dallas isn’t coastal, but our summer storms plus irrigation overspray will eat unprotected aluminum over time. Once the finish is compromised, the frame weakens and the seal fails.
- Cracked or fogged glass in an impact-rated unit. A cracked impact window won’t perform as rated. If your ES Windows addition has a laminated pane with a crack, replace the IGU before the next storm season.

AfterReplacement Cost & What’s Included
For ES Windows parts within a Dallas home addition or ADU, expect these installed ranges:
- Replacement insulated glass unit (IGU): $350 – $900 per pane, depending on size and whether it’s impact-rated.
- Sash balance replacement: $40 – $110 per window, parts and labor.
- Weatherstripping and seal replacement: $25 – $75 per window.
- Full window replacement within an addition: $4,500 – $15,000 depending on unit count and frame material.
Every price is a written number before we start. You’ll know the part cost, the labor, and the total on paper. The 365-Day Done Right Promise covers the work: if something fails inside a year, we come back and fix it at no charge, no service call fee. And we only do window part swaps and glass replacement as part of a remodeling scope; we’re not a window company doing one-off pane swaps outside a project. If it’s part of your addition or ADU, we’re on it.
DIY or Call Us?
You can safely check the model tag, photograph the failed part, and note when the failure started. You should not attempt to remove a large insulated glass unit, swap balance systems, or pull impact-rated frames yourself. Large IGUs are heavy, balances are under tension, and a dropped impact pane is a serious injury risk. Trevor Nash has pulled warped sashes out of Dallas additions that would have taken fingers if the homeowner had gone one more step. Call (940) 204-5368, tell us the model number, and we’ll give you a written number before we touch a thing.
FAQs
Expect 15 – 25 years from well-maintained ES Windows units in Dallas. Aluminum frames hold up structurally, but seals and balances tend to fail in the 10 – 15 year range under Dallas sun and humidity swings. Impact-rated units last longer if the gaskets are still sound.
Sometimes. A sticking sash is often just a balance replacement. But fogged glass means the IGU seal failed, and that’s a replacement, not a repair. We’ll tell you the truth either way and write it down.
Most balance, seal, and IGU replacements take 1 – 2 hours per window once the part is in hand. Lead time for OEM ES Windows glass typically runs 2 – 4 weeks. Call (940) 204-5368 with your model number and we’ll give you an exact timeline.
We carry common balance systems, weather seals, and hardware for the 5000 and 7000 Series. Large IGUs and impact glass are ordered per job because the sizes and ratings are unit-specific. We also stock parts for KraftMaid, Cambria, and Silestone products when the job involves those finishes.
