ES Windows Bathroom Remodeling: The Pasadena Owner’s Guide
ES Windows bathroom remodeling in Pasadena typically runs $9,000-$28,000 installed, depending on whether you’re refreshing a guest bath or reconfiguring a primary with waterproof vinyl window systems. We stock and install ES Windows-compatible frames, sashes, and sealed units across their impact-rated and non-impact vinyl lines, and we carry common sizes on our Pasadena-area trucks. Most homeowners first notice trouble when the window won’t stay open, the sash won’t lock into the jamb, or condensation appears between the panes of a unit that sits directly inside a shower surround.
We are an independent service provider - not affiliated with ES Windows - and we’ve worked their products into Pasadena bathrooms since the brand’s vinyl line expanded into the California market in the early 2010s.
Which ES Windows Models This Applies To
ES Windows organizes its residential vinyl line into series: the 5000 Series (single-hung and horizontal slider), the 6000 Series (double-hung and casement), and the 8000 Series (impact-rated for high-velocity zones). For Pasadena bathroom applications, we most commonly see the 5000 Series single-hung in 24×36, 30×48, and 36×54 rough openings, and the 6000 Series double-hung where the homeowner wants operable sashes for ventilation without sacrificing the waterproof seal.
To identify your exact unit, check the etched mark in the glass corner or the label on the jamb liner. The model prefix tells us the series; the suffix tells us the glazing option (single-pane, dual-pane Low-E, or impact-laminated). Here’s where compatibility gets tricky: ES Windows revised its jamb depth from 3¼ inches to 3½ inches in 2017, so a 2016 5000 Series sash will not seat properly in a 2018 frame. We measure on-site before ordering anything.
For OEM versus quality aftermarket, we default to ES Windows factory sashes and sealed units for anything behind a showerhead or tub surround, where the NFRC pressure rating matters for the permit inspection. For a powder room window in a dry location, we may quote an aftermarket equivalent from our vetted suppliers if the lead time on OEM stretches past three weeks.
Signs Your ES Windows Bathroom Remodeling Is Failing

- Sash won’t stay open or falls shut. The balance shoe or coil spring inside the jamb liner has worn out. In Pasadena’s hard water environment, mineral dust works into the balance mechanism faster than in coastal zones, and we’ve replaced more of these in bathrooms near the Arroyo Seco than anywhere else in the city.
- Condensation between the glass panes. The insulated glass unit (IGU) seal has failed. Once the desiccant inside the spacer bar saturates, the fogging is permanent - the IGU needs replacement, not cleaning.
- Frame corners show staining or softening. Water has penetrated the vinyl weld or the caulk joint at the sill. In older Pasadena bungalows with original plaster walls, the rough opening is often out of square, which stresses the frame and opens a gap for moisture.
- Lock won’t engage or feels loose. The keep (the metal receiver in the jamb) has shifted, or the cam lock itself has corroded from steam exposure. We see this most often on windows installed without adequate exhaust ventilation.
- Draft even when closed. The weatherstrip has compressed or the sash bowed from thermal cycling. Pasadena’s 30-degree swing between summer highs and winter lows will do this to vinyl over eight to ten years.

| Scope | Pasadena Price Range |
|---|---|
| Full bathroom remodel with ES Windows replacement | $9,000 - $28,000 |
| ES Windows sash or IGU replacement only | $400 - $1,200 |
| Full frame-out and new ES Windows unit (dry location) | $800 - $2,200 |
| Full frame-out and new impact-rated unit (shower surround) | $1,400 - $3,500 |
What drives the range: the condition of the existing rough opening, whether the wall is tile or drywall, and whether the city requires a permit for the window replacement (Pasadena does, for any structural modification or impact-rated installation). Our quote separates materials from labor so you can see exactly what the ES Windows unit costs versus the waterproofing and trim work. Under Clause 1 of the Haven Standard, that written price is delivered before anyone picks up a tool. The 365-Day Done Right Promise covers the installation; the ES Windows factory warranty covers the product itself.
DIY or Call Us?

There is one thing a homeowner can safely check: the weep holes at the sill. If they’re clogged with dust or caulk, clear them with a piece of wire and see if drainage improves. Everything else - sash removal, IGU handling, frame shimming - carries real risk. A vinyl window sash in a bathroom is heavier than it looks, and the balance mechanism is under spring tension that can release suddenly. We’ve been called to Pasadena homes where a DIY removal bent the jamb liner beyond repair, turning a $400 sash replacement into a $1,800 full-frame job.
More critically, any window inside a wet area needs proper flashing integration with the shower waterproofing membrane. Miss that detail and you’re looking at subfloor rot in six months. If you’re pricing the work, call (562) 203-4508 and we’ll deliver a written scope with the brands named and the labor separated - then you can decide.
FAQs
Expect 15 to 20 years for the frame and 10 to 15 for the IGU, shorter if the bathroom lacks an exhaust fan or if the window sits inside a direct spray zone. Call (562) 203-4508 for an exact quote on replacement - estimates are free.
No. Once the seal fails and fogging appears between the panes, the IGU is a sealed assembly that cannot be disassembled and resealed in the field. Replacement is the only fix. Call (562) 203-4508 for an exact quote - estimates are free.
A sash or IGU swap takes two to four hours. A full frame-out with waterproofing integration takes one to two days, plus a 24-hour cure time for the membrane before tile or surround goes back. Call (562) 203-4508 to schedule - estimates are free.
We carry common 5000 and 6000 Series sashes, balances, and lock hardware for the sizes we see most often in Pasadena bathrooms. Odd sizes and impact-rated IGUs we order with a three- to five-day lead time. Call (562) 203-4508 to confirm availability for your unit - estimates are free.
Write it down before you build it - scope first, surprises later. That’s how Grant Rowan has run every job since he started in the San Gabriel Valley, and it’s why we separate materials from labor on every quote we deliver in Pasadena.
