ES Windows Home Additions & ADU: The Fresno Owner’s Guide
ES Windows home additions and ADU projects in Fresno typically run $45,000 to $130,000 fully installed, with ADU construction landing between $90,000 and $220,000 depending on size, foundation work, and utility runs. We quote these jobs with a written price before any work starts, and we install ES Windows-compatible window packages across the addition or ADU shell so the glazing, framing, and flashing line up correctly the first time. Most Fresno homeowners discover they need this level of work when a window fails, a wall settles, or a growing household outpaces the current floor plan, and the band-aid repairs no longer make sense. We’re Bradford Remodeling Co Fresno, an independent contractor, not affiliated with ES Windows, but we work with their product lines regularly and know what the install demands.
What “squared away” looks like here: a clean site at close, a documented scope that matches the signed estimate, and a written 365-Day Done Right Promise in your hand. Curtis Lane runs our Fresno operation, and the standard is simple. The estimate says what we build, and we build what the estimate says.
Which ES Windows Models This Applies To
We handle ES Windows products across the board: fixed picture windows, single-hung, double-hung, sliders, casements, and the multi-panel configurations that show up on larger additions and ADU builds. The key compatibility gotcha with ES Windows is the frame depth and mullion layout. The rough opening dimensions have to match the specific series, because the nailing flange and the interior trim reveal are not universal across their catalog. Get the wrong series in the same nominal size and you’ll be shimming a half-inch gap or trimming back drywall that should have been right the first time.
To identify your ES Windows model, check the aluminum or vinyl frame for a factory sticker, usually on the head jamb or the edge of the sash. It carries a serial number and series code. If the sticker is gone, measure the visible glass width and height, then the full frame depth from the exterior face to the interior face. Those three numbers narrow it down fast. OEM replacement sashes and hardware are worth the cost when the window is under 12 years old. For older units, quality aftermarket glazing and balances often perform as well and cost 20 to 30 percent less. We’ll walk you through that decision with the actual numbers on the table.

Signs Your ES Windows Home Additions & ADU Is Failing
- Condensation between the glass panes. The seal has failed and the argon or krypton gas fill is gone. The window’s thermal performance is finished, and in Fresno summers that means real heat gain. The fix is a new sash or a new window, not a wipe-down.
- Cranking hard or the sash dropping when it should stay open. The balance system or operator gear is worn. This is the most common failure on casement and single-hung ES Windows units after eight to ten years of daily use.
- Visible daylight or drafts at the frame corners. The rough opening has shifted or the flashing has failed. Fresno’s clay soil moves with moisture, and older additions often settle enough to rack a frame just enough to break the weather seal.
- Water staining or soft drywall below the window. The sill pan or the exterior flashing failed. This is a framing and moisture problem, not a window-cleaning problem, and it worsens every winter rain season.
- Locking hardware that won’t engage or a sash that doesn’t seat square. The frame has racked out of square, or the hardware has worn past adjustment. This matters for security but also indicates the window itself is at the end of its service life.

AfterReplacement Cost & What’s Included
A full home addition or ADU build with ES Windows-compatible window packages in Fresno runs $45,000 to $130,000, and an ADU as a standalone structure lands at $90,000 to $220,000. Window replacement within an existing structure runs $4,500 to $15,000. The spread depends on square footage, foundation type, utility runs, and whether we’re matching an existing ES Windows series or starting fresh with a clean rough opening. A smaller addition with simple gable framing and two or three windows sits at the low end. A permitted ADU with a bathroom rough-in, kitchenette, and separate electrical panel does not.
Every bid includes the parts, labor, flashing, trim, and disposal. No numbers move at the door. The written price covers what it covers, and the 365-Day Done Right Promise means if the work fails within a year, we return and correct it at no charge. That guarantee is in writing before we start.

DIY or Call Us?
You can check the window labels, measure the frame depth, and look for daylight or water staining without touching a tool. That information helps us give you an accurate price faster. What you shouldn’t do is pull a window out of a load-bearing wall or cut a new rough opening without understanding the header and shear requirements. Additions and ADUs involve structural work, electrical, and plumbing rough-ins. A wrong header or an improperly flashed opening fails quietly for years, then expensively all at once.
We’re background-checked and uniformed, and a live person answers our phone at (559) 785-2712 any hour. If you’re weighing a repair against a full addition or ADU build, call and we’ll give you the straight picture and a written price.
Frequently Asked Questions
Expect 15 to 25 years from the frame and hardware, with sealed glass units typically failing between 10 and 15 years in Fresno’s summer heat. South-facing and west-facing windows lose their seals sooner because the constant sun exposure stresses the spacer and sealant. Call (559) 785-2712 and we’ll assess what’s actually failed versus what’s just showing normal wear.
Yes, if the failure is limited to the balance system, operator gear, or weatherstripping, a component repair makes sense and runs far less than full replacement. If the sealed glass has fogged or the frame is racked, replacement is the honest fix. We’ll tell you which one applies to your unit and quote the repair path first when it’s viable.
A window replacement in an existing structure is typically one to two days per opening. A full addition or ADU runs eight to sixteen weeks depending on scope, permitting, and weather. Your written estimate includes the schedule, and we hold to it.
We stock common hardware and seal components on the truck, and we order series-specific sashes and frames directly through our supplier network. We also work with KraftMaid, Cambria, and Silestone products when the project extends into interior finishes. Lead times on custom ES Windows glass run two to four weeks in Fresno, and we factor that into the schedule up front.
