ES Windows Sliding & Patio Doors: The Boca Raton Owner’s Guide
We stock and install ES Windows-compatible sliding and patio door systems in Boca Raton, with typical installed replacement costs running $1,800 to $4,200 depending on glass package and frame size. Most ES Windows units we source arrive within 3 to 5 business days, and we keep common rollers, tracks, and locking hardware on our trucks for same-day service calls. Most Boca Raton homeowners discover a problem when the door sticks in the track during humid summer mornings, or when they notice the locking points no longer draw the active panel tight against the weatherstrip after a storm season.
Which ES Windows Models This Applies To
ES Windows produces several sliding and patio door series, and the parts are not interchangeable across all of them. The ES 8000 Series and ES 9000 Series are the two impact-rated lines we see most often in Boca Raton installations from 2016 onward. The 8000 uses a 2 1/4-inch frame depth with a flat sill profile; the 9000 steps to 2 5/8 inches with a beveled sill and heavier wall thickness. The label is usually etched into the glass corner or stamped on the vertical frame edge of the fixed panel - look for a four-digit date code and the series prefix.
Roller assemblies differ between these series. The 8000 uses a 1 1/2-inch tandem roller with a stamped steel housing; the 9000 uses a 1 3/4-inch adjustable roller in an extruded aluminum bracket. We stock both OEM ES rollers and a quality aftermarket equivalent from C.R. Laurence that matches the axle spacing and wheel durometer. The aftermarket roller runs about $40 less per pair and carries the same 5-year warranty in our experience. We do not recommend generic big-box rollers - the axle diameter is often 1/16 inch undersized, which wallows out the mounting slot within two years of Boca Raton’s salt-air exposure.
Track replacement is another common mismatch. ES Windows switched from anodized to powder-coated track extrusions around 2019. The anodized track (pre-2019) measures 0.090 inch wall thickness; the powder-coated version runs 0.125 inch and uses a different interlock geometry. If your door was installed between 2015 and 2019, bring us the old track section or a clear photo of the cross-section - we’ll match it before ordering.
Signs Your ES Windows Sliding & Patio Door Is Failing

- The panel drags or requires shoulder weight to move. This usually means the roller wheels have flat-spotted from debris in the track, or the axle bearings have corroded from condensation trapped in the housing. In Boca Raton, we see this accelerate when irrigation spray hits the sill repeatedly - the chlorinated water pits the roller axle.
- The lock thumbturn rotates but the bolts don’t extend. The multi-point lock mechanism has a stripped spindle or a bent cam. ES Windows uses a 7/8-inch backset on most patio doors, and the internal gearbox is not field-serviceable - the entire lock body swaps out as one unit.
- Daylight shows between the panels when closed and locked. The interlock weatherstrip has compressed past recovery, or the panel has dropped on worn rollers and no longer sits at the correct height to mate with the frame jamb. This gap kills your energy efficiency and lets driving rain into the track during a tropical system.
- The fixed panel glass fogs between the panes. The insulated glass unit (IGU) seal has failed. ES Windows uses a dual-seal system - polyisobutylene primary seal and silicone secondary - but Boca Raton’s thermal cycling eventually wins. The IGU is replaceable without changing the frame; we measure the daylight opening and order a direct replacement with the same Low-E coating and argon fill.
- Corrosion pits appear on the exterior frame corners. This is galvanic corrosion between the aluminum frame and a dissimilar-metal fastener, or salt accumulation in a drain hole that never cleared. Caught early, we can clean, treat, and seal the area. Left alone, the frame wall thins and the corner joint loosens.

AfterReplacement Cost & What’s Included
Here is how we price ES Windows sliding and patio door work in Boca Raton. Every figure is written on the measured survey we leave with you before any work starts.
| Service | Typical Range |
|---|---|
| Roller pair replacement (labor + parts) | $280 - $420 |
| Multi-point lock assembly replacement | $340 - $580 |
| Track section replacement (partial) | $450 - $720 |
| Full track replacement | $680 - $1,100 |
| IGU replacement (fogged glass) | $520 - $890 per panel |
| Complete door replacement (installed) | $1,800 - $4,200 |
The wide range on complete replacement reflects three variables: fixed panel versus two-panel slider, standard glass versus impact-rated laminated, and whether the rough opening needs reframing. A 6-foot two-panel slider in non-impact glass sits at the low end; an 8-foot three-panel lift-slide in impact-rated with Low-366 coating and a recessed sill pan sits at the high end. We specify the exact glass package by U-factor and SHGC (solar heat gain coefficient) - the numbers that determine your FPL rebate eligibility and your summer cooling load.
Every parts replacement carries our 365-Day Done Right Promise under the Haven Standard. If the roller we install chatters in six months, we replace it and correct whatever caused the premature wear. No requote, no argument. The complete door replacement includes a documented photo record of the rough opening, the shim pattern, the sealant application, and the final lock engagement test.
DIY or Call Us?

There is one safe check a homeowner can make: vacuum the track thoroughly and flush the weep holes with fresh water. If the door still drags, the problem is inside the frame, and that is where DIY stops being sensible.
Removing an ES Windows patio door panel requires tilting it out of the track while it weighs 80 to 140 pounds depending on glass package. The panel is top-heavy, the frame edges are sharp, and a dropped panel destroys the glass, the floor, or a foot. We have replaced panels that homeowners damaged during self-service attempts, and the cost always exceeds what the service call would have run.
The multi-point lock mechanism contains spring-loaded bolts under tension. Disassembling it without supporting the bolt carriers can launch small parts into the room or into your eye. We do not document this for DIY replication.
Measure it twice, write it down, then we can talk price. Call (561) 200-8592 and we will schedule a no-charge assessment. If you have a competitor’s written estimate, bring it - Haven Clause 5 means we review it at no charge and tell you exactly where the scope differs from what we would specify.
FAQs
In Boca Raton’s coastal climate, expect 8 to 12 years from OEM rollers with basic maintenance - track cleaning and annual silicone spray on the axle. Homes within a mile of the Intracoastal or the ocean see closer to 6 to 8 years due to salt-air corrosion of the axle bearings. Call (561) 200-8592 for an exact quote on replacement - estimates are free.
The insulated glass unit (IGU) can be replaced independently of the frame. We measure the daylight opening, order a replacement IGU with matching Low-E and argon specifications, and install it with a new glazing bead and setting blocks. The frame stays in place. This typically costs 40 to 50 percent less than full door replacement. Call (561) 200-8592 for an exact quote - estimates are free.
Most residential replacements in Boca Raton take one day for a standard two-panel slider, assuming the rough opening is sound. A three-panel lift-slide or a unit requiring reframing takes two days. We do not promise same-day completion on planned construction work - the Haven Standard requires that we verify square, plumb, and sealant cure before we sign off. Call (561) 200-8592 to schedule your measured survey.
We carry the most common failure items: 8000 and 9000 series roller pairs, multi-point lock bodies, weatherstrip kits, and track sections in standard widths. Specialized glass packages and complete door units are ordered to specification after the measured survey. If your part is on the truck, we fix it that visit. If not, we order it with tracked delivery and return to install - no second trip charge. Call (561) 200-8592 to confirm availability for your specific model.
