ES Windows Home Additions & ADU: The Dallas Owner’s Guide
If you’re planning a home addition or ADU and want ES Windows specified, the installed price range in Dallas runs $45,000 to $130,000 depending on square footage, foundation work, and how much of the ES Windows product line you’re using. Bradford Remodeling Co Dallas installs ES Windows as part of room additions, detached ADUs, and garage conversions, and we put the window package in writing before the first wall goes up. Most Dallas owners reach this page because they’ve got a failing aluminum frame in a 1990s sunroom addition, or they’re building new and want the ES Windows product matched to the rest of the house without getting stuck with a mystery quote.
At Bradford Remodeling, we treat ES Windows as a named spec, not a guess. That means if you’re adding a bedroom wing with ES Windows casements, or converting a garage into an ADU with ES Windows sliders, we’ll pull the actual series number, verify the frame depth, and price the package as a line item. You’ll know what the windows cost, what the rough-in costs, and what the finished trim package costs before we ever pull a permit. That’s how we work, and it’s why a written price is standard on every job we do in Dallas.
Which ES Windows Models This Applies To
ES Windows makes vinyl and aluminum window systems in several series, and they are not all interchangeable. On Dallas additions we commonly see the ES Windows 7000 series (single-hung and casement, with a 2-5/8 inch frame depth) and the 9000 series impact-rated line used on homes that need windborne debris protection. The frame depth matters because it sets the rough opening size, and if the wrong series is ordered, the window will not seat in a 2×4 wall without shimming the entire rough opening. We check the series label on the existing windows when we match a product; on new work we specify the series in the scope so there is no substitution at the supplier counter.
For replacement glass or sashes in an existing ES Windows addition, the right part comes down to the glass pack size and the balance system. ES Windows uses coil balances on many double-hung units, and the weight rating is stamped on the metal housing. If you replace the glass with a heavier laminated unit, the original balance will not hold the sash up. We see that in Dallas sunrooms where owners upgrade to Low-E glass and the window suddenly drops when opened. The fix is a new balance, not a new window, and it’s a parts-and-labor job we handle in one visit when the unit is in stock or available from our Dallas suppliers.
Bradford Remodeling Co Dallas is an independent contractor, not affiliated with ES Windows. We use their products because they hold up in Texas heat when they are installed correctly, and because we can get parts through our local supply house without a three-week hold.

Signs Your ES Windows Home Additions & ADU Is Failing
- Sash drops when you open the window. The coil balance has lost tension or the pivot pin is worn. In a Dallas addition built 15 to 20 years ago, the original balances are near the end of their service life, especially on the west-facing walls that catch afternoon sun.
- Condensation between the panes. The insulated glass unit’s seal has failed. Once the desiccant inside the spacer is saturated, you cannot dry it out from the outside. The glass pack gets replaced, and on ES Windows units the replacement glass is ordered by the etched manufacturer code on the spacer bar.
- The window is hard to lock or does not seal at the meeting rail. The interlock on ES Windows double-hungs can warp slightly over years of thermal cycling in Dallas. If the sash is bowed by a few millimeters, the lock will bind. Sometimes the fix is a new sash, not a new frame.
- Daylight at the corners of the frame. The installation was not shimmed correctly, or the rough opening was cut too large. In a home addition this usually points to settling or to the original framer not building the opening to the window’s exact rough-opening spec. We square the opening and reset the window with proper shims and backer rod.
- Water staining on the interior drywall under the window. This is a flashing or sill-pan failure, not a window glass failure. On ES Windows units the weep holes can clog with Dallas dust and allow water to pool in the track, which then finds the path of least resistance into the wall cavity. We pull the window, install a proper sill pan, and re-flash the opening with tape and metal drip edge.

AfterReplacement Cost & What’s Included
A home addition or ADU in Dallas using ES Windows runs $45,000 to $130,000 as a complete project. Within that, the ES Windows package itself typically accounts for $6,000 to $24,000 depending on the window count, series, and whether you need impact-rated glass. Here is how the line items break out:
- ES Windows package on a single-room addition (6 to 10 windows): $6,000 – $18,000
- ES Windows package on a full ADU (12 to 20 windows and sliders): $12,000 – $24,000
- Window replacement with ES Windows in an existing addition: $4,500 – $15,000 depending on count
- Glass pack replacement for a failed ES Windows IGU: $350 – $1,200 per window, parts and labor
- Coil balance replacement on a ES Windows double-hung: $180 – $400 per window, parts and labor
The range moves on three things: foundation work for the addition, the ES Windows series you choose, and whether the existing framing is square enough to accept the windows without corrective carpentry. Every Bradford Remodeling job in Dallas gets a written price before work begins, and that price includes the window package, rough-in, flashing, interior trim, and job cleanup. You will not get a number that moves at the door.
All completed work carries the 365-Day Done Right Promise. If the windows or any part of the addition fails inside the first year, we come back and make it right at no charge. You get that in writing, signed, before we leave the site.
DIY or Call Us?
For an existing ES Windows unit, there are a few things an owner can check safely. Clean the tracks and weep holes with a soft brush and vacuum. Check that the screws on the lock and keeper are tight. Look at the balance housings for a stamped weight rating and note it before calling so we bring the right part. Do not remove a sash from an ES Windows double-hung without knowing how to release the pivot pins and relieve the balance tension. A loaded coil balance under that metal housing will take a fingertip off if it lets go while the sash is out. We have seen it. That’s not a scare tactic; it’s the honest math on a spring that holds a 30-pound sash in place.
On new work, an addition or ADU is not a parts job. It’s a framing, electrical, HVAC, insulation, drywall, and window package that has to pass Dallas inspection. Curtis Lane has been running crews in this market long enough to know which inspectors want sill flashing taped a certain way and which ones check the rough opening tolerances with a level. If your ES Windows are failing in an existing addition, or you’re planning new construction, call (903) 326-8963 and we’ll give you a straight number and a real scope.
FAQs
ES Windows frames will typically last 25 to 35 years in Dallas before the balances wear out or the seals fail, but the glass packs often need replacement at the 12 to 18 year mark because Texas heat cycles the sealant faster than a mild climate would. The frames themselves are durable; the moving parts and the insulated glass are the consumables. Call (903) 326-8963 if yours are failing and we’ll tell you whether it’s a repair or a replacement.
Yes, in most cases a failed coil balance, pivot pin, lock, or glass pack can be repaired without replacing the whole window. The exception is a bowed or warped sash, which usually needs a new sash or a full unit. We quote the repair price and the replacement price side by side so you can make the call with real numbers in hand.
A glass pack or balance replacement on an existing ES Windows unit takes one visit, typically two to four hours depending on access. A full window replacement in an existing addition takes one to three days. A full home addition or ADU with ES Windows takes eight to sixteen weeks depending on scope, and we put the schedule in the written scope before you sign so you know what delivery day looks like.
We keep common coil balances, pivot pins, and locks on the truck for standard ES Windows double-hung and single-hung units. Glass packs are ordered by the etched code on the spacer bar and typically arrive in five to ten business days through our Dallas supplier. If you need the window quickly, call (903) 326-8963 and we’ll confirm lead time before we schedule, so there’s no gap between the promise and the part.
