ECO Window Systems Bathroom Remodeling: The Fresno Owner’s Guide
If you’re looking at a bathroom with ECO Window Systems windows or glass block and wondering whether the surrounding remodel can be done without tearing out those units, the short answer is yes. A full bathroom remodel in Fresno that works around existing ECO Window Systems installations typically runs $9,000 to $28,000 depending on scope, and we can usually start the planning conversation the same week you call. Most owners discover the intersection of their ECO windows and a bathroom remodel the hard way: water intrusion at the sill, dry rot spreading into the substrate around the frame, or a window that no longer opens because the rough opening has shifted. The window itself is rarely the problem. It’s what the last contractor did, or didn’t do, around it.
Bradford Remodeling Co Fresno is an independent remodeling contractor. We’re not affiliated with ECO Window Systems, and we don’t pretend to be. What we do is plan bathroom work around their units correctly, from the rough-in stage to the final waterproofing, so the window stays sound and the shower doesn’t leak into the wall cavity.
Which ECO Window Systems Models This Applies To
ECO Window Systems produces vinyl-frame windows in several series, and the compatibility question comes down to frame depth, mounting flange, and whether the unit was installed as new construction or a retrofit. In bathrooms, you’re usually dealing with two scenarios: a standard double-hung or slider above a tub or vanity, or a fixed glass block unit that shares a wall with the shower surround. The frame depth matters because your tile backer board, waterproofing membrane, and finish tile all have to plane out flush with the window jamb. If the existing rough opening is out of square by even a quarter inch, which we see constantly in older Fresno homes from the 1950s through the 1980s, the finish work around an ECO unit will show it.
The OEM versus aftermarket decision only matters if you’re replacing the window itself. For a bathroom remodel where the window stays in place, the real “part” is the flashing and sealant system around it. We use manufacturer-specified flashing tape and backer rod, not whatever caulk is on sale. If the window does need replacing, ECO’s published rough opening and frame dimensions are straightforward, and we’ll spec the replacement to match the existing series rather than forcing a generic unit into the hole. We also work with KraftMaid, Cambria, and Silestone products for the rest of the bathroom, but the window is what drives the waterproofing sequence.

Signs Your ECO Window Systems Bathroom Remodel Is Failing
- Peeling paint or bubbling drywall around the window casing. That’s moisture working its way through the sealant joint. In a Fresno summer, the stucco expands; in January, it contracts. The sealant eventually loses adhesion, and water follows.
- Black staining at the bottom corners of the window jamb. This is mold, and it means water has been sitting in the jamb pocket long enough to wick into the framing. By the time you see the stain, the damage behind the tile or drywall is usually worse than it looks.
- The sash binds or won’t open smoothly. A bathroom window that sticks is often a sign the rough opening has shifted or the framing around it has swelled. Not a window defect. A framing or substrate problem that any good remodel now has to address.
- Tile grout cracking in a straight line running from the window corner. Grout cracks in patterns. A straight crack pointing at a window corner usually means movement at the opening, not just old grout.
- You feel cool air around the window frame in winter. Fresno’s winter mornings get down near freezing, and an unsealed window frame will announce itself. The missing air seal also lets shower steam escape into the wall cavity, which is the slow killer behind most bathroom rot.

AfterReplacement Cost & What’s Included
A bathroom remodel in Fresno that involves working around or replacing an ECO Window Systems unit falls in the $9,000 to $28,000 range. Here’s the line-item reality:
- Tub-to-shower conversion around existing window: $3,500 to $10,000
- Walk-in shower with window waterproofing: $4,500 to $12,000
- Full bathroom remodel including window trim, substrate repair, and fixtures: $9,000 to $28,000
- New bathroom vanity with Cambria or Silestone top: $800 to $3,000
What moves the number is the condition of the studs and sill plate behind the window. If the water damage is contained to the trim, it’s a minor prep item. If we have to pull out a rotted king stud and sister in new framing, the scope grew for a reason, and we’ll show you the photo and the written change before we touch it. That’s The Garrison Standard: a written price before any work starts, and no numbers that move at the door. Every finished project carries the 365-Day Done Right Promise. If the waterproofing or finish fails within a year, we come back and correct it at no charge.
DIY or Call Us?
You can safely scrape the old caulk off an ECO window frame and inspect the joint yourself. You can check the weep holes at the bottom of the frame to see if they’re clogged with mineral scale. You can run a thin blade along the jamb to test whether the drywall behind the casing cover is soft. That’s where DIY should stop. The moment a homeowner starts cutting out drywall around a window in a wet area, they’re into the water management envelope, and one wrong flashing detail sends shower water into the wall for years before anyone notices. Water is the most expensive contractor in Fresno. It bills you later, and it never leaves a written estimate.
If you suspect the opening around your ECO window has water damage, call us at (559) 785-2712. We’ll take a look, tell you what’s actually wrong, and put the fix in writing.
FAQs
A properly installed ECO window in a bathroom should last 20 to 30 years, but the sealant and flashing around it are wear items that need attention every 8 to 12 years in Fresno’s heat. The window itself fails before then only if water was allowed to sit against the frame. Call (559) 785-2712 if you want us to check whether your window is the problem or the install around it is.
Yes, if the frame is sound and the glass is intact, we can usually salvage the existing ECO unit and rebuild the waterproofing around it. That’s the lower-cost path in most Fresno bathroom remodels. We’ll tell you honestly if replacement is the smarter money, because patching a failing frame just means paying twice.
A standard tub-to-shower conversion with the window kept in place takes about 10 to 14 working days in Fresno, depending on tile selection and whether we find hidden framing damage. A full bathroom remodel runs 3 to 5 weeks. You’ll have a written schedule with the estimate, and we stick to it within days, not weeks.
We keep the flashing tapes, sealants, backer rod, and substrate materials for bathroom work on the truck, so there’s no mid-job run to a supply house for the basics. For window replacement units, we order to spec from ECO’s published dimensions. Call (559) 785-2712 and we’ll tell you what’s in stock and what needs ordering.
