ES Windows Door Replacement in Pasadena: What to Know First
ES Windows door replacement in Pasadena typically runs $1,800 to $5,600 depending on the door type, glass package, and whether the slab or the full frame gets replaced. Juniper Windows Pasadena handles the work as an independent ES Windows service provider, not a manufacturer-authorized shop, which means we can source OEM or quality aftermarket parts based on what actually makes sense for your home and budget. Most replacements take one full day for a standard slab, or 2 to 3 days when the rough opening needs reframing. If you own a ES Windows product and the door is sticking, sagging, or leaking air, call (626) 657-5977 and we’ll give you a written price before anything gets ordered.
How ES Windows Products Fail – and How We Fix Them
- Sagging hinges on the ES H-Series sliding patio door (pre-2016 builds). Older H-Series used a two-roller carriage that wears unevenly on the Pasadena side facing afternoon sun. The door starts dragging about a quarter-inch low on the strike side. We replace the carriage with the updated four-roller kit and re-drill the adjustment slot if the track shows galling. It’s a half-day fix, not a full door replacement, unless the track itself is deformed.
- Warped stiles on the ES 8700 French door when exposed to west-facing sun. The 8700’s engineered-wood stile was never designed for a full Pasadena afternoon on an unshaded patio. We see a 3/16-inch bow that breaks the weatherstripping seal. If the slab is otherwise sound, we can sometimes re-hang with a stiffer hinge set and new compression weatherstrip. If the warp has pulled the lock stile out of alignment, slab replacement is the honest call.
- Failed interlock weatherstripping on ES impact-rated French units. The interlock gasket on impact-rated ES doors dries out and goes hard in our dry heat, then tears when the inactive panel gets yanked against it. You’ll feel a vertical draft right at the center seam. We’ll pull the panel, replace the interlock with a closed-cell foam profile that holds up better in low humidity, and reset the panel gap to spec.
- Aluminum threshold pitting on ground-floor ES sliders in the Arroyo Seco corridor. Irrigation overspray plus mineral-heavy Pasadena water eats anodized thresholds faster than folks expect. Once the top surface pits, water wicks under the track and into the subfloor. We replace the threshold with a thermally broken unit and re-flash the pan, because caulk alone won’t fix it. If the subfloor shows rot, we’ll open it up and replace the damaged section before the new threshold goes in.
- Stripped lock mortises on ES single-entry doors with the Keil lock body. The Keil mechanism’s deadbolt throw is longer than most, and in a home that’s settled an eighth-inch, the bolt drags on the strike and eventually chews out the mortise screws. We fix it by through-bolting the strike with 3-inch screws into the jack stud, then adjusting the threshold so the deadbolt aligns without force. No new door needed if the slab is straight.
Our ES Windows Door Replacement Process
- 1
Call and get a live person. You reach us at (626) 657-5977, 24/7. We’ll ask about the door model, the symptom, and what side of the house it’s on, then book a diagnostic visit.
- 2
Diagnostics at YOUR door. Sean or one of our techs shows up in a uniform, checks the rough opening for square, measures the slab for warp, and pulls the hinge covers to see what’s actually failing. You’ll get a plain-English explanation of what we found.
- 3
Written quote, no guesswork. We give you a line-item price before anything gets ordered. If it’s a slab replacement, the quote includes disposal. If it’s a full frame replacement, the quote includes flashing and any required stucco or trim touch-up.
- 4
Parts call. We’ll tell you if OEM is the right move (warranty-safe) or if a quality aftermarket part does the same job for less. You decide. We never lock you into one supplier.
- 5
Install day. We set the new door, shim for plumb and level, re-flash the pan, adjust the threshold, and test the reveal gaps top to bottom. Before-and-after photos go to you.
- 6
Cleanup and walkthrough. We haul off the old slab and hardware, then walk the door with you. You get the 365-Day Done Right Promise in writing: parts and labor covered for a full year.

FAQs
In most cases you can replace just the slab. We replace the slab when the frame is square, the threshold is sound, and the rough opening hasn’t rotted or shifted. A full frame replacement is only necessary if the frame itself is warped, water-damaged, or the rough opening needs reframing due to settling. During diagnostics we’ll tell you which path makes sense, and the written quote reflects only what’s needed. Call (626) 657-5977 for an exact answer.
In many cases, no. ES Windows warranties cover the product, but replacing a failed slab or hardware with OEM parts generally does not void the remainder of the warranty on other components when the work is done correctly. We are an independent provider, not an ES Windows authorized shop, so we’ll recommend OEM parts where warranty coverage matters and aftermarket parts where cost savings make more sense. Call (626) 657-5977 and we’ll walk you through your specific warranty language.
Most ES Windows replacement parts arrive within 5 to 10 business days. Hardware like hinges, rollers, and interlock weatherstripping typically ships faster, while custom-sized impact-rated slabs can take 2 to 4 weeks depending on the glass package. We’ll give you a parts lead-time estimate at the diagnostic visit so you know exactly how long the process takes before you commit. Call (626) 657-5977 for a current parts timeline.
If the slab is straight and the hardware is still available, repair is usually the smarter money, typically $200 to $600 for hinge, roller, or weatherstripping replacements. If the slab is warped, the glass seal has failed, or the frame has water damage, replacement is the honest call. We’ll show you the measurements and let you make the decision with all the numbers in front of you. Call (626) 657-5977 for a diagnostic visit and a written recommendation.
