ES Windows Impact Windows & Doors in Lantana: What to Know First
We install, replace, and service ES Windows impact windows and doors in Lantana as an independent ES Windows service provider. Most ES Windows jobs we handle run from $340 to $1,850 per opening depending on series, size, and whether the existing frame can be retained. We show up with a measured survey you keep, and the written price on that document is the price on the invoice - no change orders, no surprises.
This page is for Lantana homeowners who already own ES Windows products or are comparing them against PGT, CGI, CWS, or ECO Window Systems for a hurricane-rated upgrade. If you’re seeing seal failure, hardware drag, or impact-layer delamination on your ES Windows units, call (561) 461-2062. We’ll schedule a free measured survey and give you a written quote before any work starts.
How ES Windows Products Fail - and How We Fix Them
- ES Windows 8100 Series single hung: sash drift and tilt-latch cracking. The 8100’s tilt mechanism uses a glass-filled nylon latch that stiffens after four to six years of Lantana’s UV exposure and salt-air cycling. We see the sash drop an inch or fail to lock closed. Our fix: we source the OEM latch set or, when ES Windows backorders run long, a tested aftermarket equivalent with the same 85 lb shear rating. We replace both latches even if only one failed - the other is fatigued.
- ES Windows 5000 Series horizontal roller: wheel carriage corrosion and track galling. The 5000’s stainless roller housing meets an aluminum track, and in Lantana’s coastal environment that galvanic pair seizes if the weep holes clog with sand. The sash jams halfway open. We pull the sash, machine the track flat, replace with marine-grade polymer rollers, and clear every weep channel. The door rolls lighter than it did new.
- ES Windows impact laminated glass: edge delamination (“white haze” at the perimeter). This is moisture ingress between the glass and the SentryGlas or PVB interlayer, common on west-facing units in Lantana where afternoon rain hits hot glass. It starts at the edge and creeps inward. We measure the affected area - under 2 inches from the seal, we can sometimes re-edge seal; beyond that, the lite gets replaced with a new impact-rated unit matched to the original design pressure.
- ES Windows 4100 Series fixed picture window: frame bow and sill ponding. The 4100’s narrow frame profile flexes on openings over 48 inches if the original installer didn’t shim to plane. Water ponds on the sill and breaches the sill pan. We remove the unit, reframe the rough opening with composite shims set to 1/4 inch per foot slope, and reinstall with a continuous bead of backer rod and sealant. The fix outlasts the original install because we measure the slope with a laser, not a level.
- ES Windows multi-point lock system: spindle wear and misalignment. The multi-point gear on ES Windows swinging doors uses a brass spindle that elongates its keyway after heavy use. The handle turns but the bolts don’t engage. We replace the gearbox with the exact ES Windows part number - aftermarket gearboxes often have 2mm spindle offset differences that throw off the strike alignment. We test every point with a feeler gauge before we leave.
Our ES Windows Impact Windows & Doors Process

- 1
Measured survey. We record every opening to the sixteenth: rough opening width, height, squareness, and sill slope. You keep the survey sheet. This is the document the quote comes from.
- 2
Diagnostics with photos. We photograph the failure - seal condition, hardware wear pattern, frame deflection - and note the ES Windows series, size code, and design pressure rating stamped on the frame.
- 3
Parts decision. We check OEM availability against lead time and price. If ES Windows has the part in Miami, we order it. If not, we specify a quality aftermarket alternative with matching performance data - never a guess.
- 4
Written scope and price. You get a line-item quote: labor, materials, disposal, permit if required. The price on this document is the price on the final invoice. Haven Clause 1.
- 5
Installation and testing. We install to manufacturer spec, then test: sash operation, lock engagement, weep flow, and visual seal inspection. We record everything.
- 6
Photo record and warranty. You get the documented photo record by email. The 365-Day Done Right Promise is stamped on your paperwork. If it’s not right, we make it right.

Why Lantana Homeowners Call Sightline Windows & Doors Lantana for ES Windows Work

We’ve measured and installed windows along the Lantana beachfront corridor where salt air and summer storms test every seal and hinge. Sonia Raman started this practice in 2012 under the Haven Standard, and our crew has handled ES Windows, PGT, CGI, CWS, and ECO Window Systems across more than 18,000 openings. That multi-brand fluency matters: if your ES Windows part is backordered, we can specify a functionally equivalent solution from another verified line rather than leave you waiting through hurricane season.
Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. Calls are answered by a live person, 24/7. And the 365-Day Done Right Promise is not a courtesy; it’s written into every job. Measure it right the first time. Everything after that is just paperwork.
FAQs
No - independent service does not void your ES Windows product warranty, provided the repair uses parts and methods that meet their specifications. We document the part numbers and installation details so your warranty record stays clean. If your unit is still under ES Windows’s original warranty, we note that on your paperwork and flag any items that should be handled through their channel first. Call (561) 461-2062 and we’ll review your warranty status during the free survey.
OEM parts from ES Windows’s Miami distribution typically arrive in 5 to 10 business days for standard hardware and rollers; impact-rated lites can run 2 to 4 weeks depending on size and interlayer specification. When lead times stretch, we stock quality aftermarket alternatives for hardware items that meet the same performance ratings - we don’t install them without showing you the spec sheet. Call (561) 461-2062 and we’ll check availability for your specific series before we schedule.
Repair makes sense when the frame is square, the glazing is intact, and the failure is isolated to hardware, rollers, or seal. Replace when you see frame rot, repeated seal failure, or when the design pressure rating no longer meets current Florida Building Code for your exposure zone - common in older Lantana homes east of Ocean Avenue. We give you both numbers on the written quote: repair price and replacement price. Call (561) 461-2062 for the measured survey.
Yes, if the series is still in production. We record the size code, color formula, and grid pattern from your existing frame sticker or our field measurement, then order from ES Windows or cross-reference to a compatible profile from PGT, CGI, or CWS if the line has been discontinued. The match includes sightline width, frame depth, and exterior face profile - not just the glass size. Call (561) 461-2062 and we’ll verify matchability on site.
Check for the permanent mark: every ES Windows impact unit has a label or etched marking showing the design pressure (DP) rating, the test standard (ASTM E1886/E1996 or Miami-Dade County PA 201), and the manufacturer. If the label is painted over or missing, we can identify the series from frame profile dimensions and glazing edge detail. Non-impact ES Windows units exist - we see them in Lantana additions from the mid-2000s where the original owner upgraded aesthetics without the impact glass. Call (561) 461-2062 and we’ll verify your rating during the free survey.
