ES Windows Custom & Geometric Windows in West Palm Beach: What to Know First
We install and service ES Windows custom and geometric products in West Palm Beach as an independent ES Windows service provider. Most measured surveys for shaped openings - arches, circles, trapezoids, and oversized custom units - are scheduled within 48 hours, with typical custom orders running 8-14 weeks depending on the series and glass specification. Our written quote is the final invoice; if the number isn’t on the page, it isn’t in the price.
This page is for West Palm Beach homeowners who already own ES Windows products or are specifying them for a new custom opening and need a technician who understands the difference between the Impact Plus line’s laminated glass stack and the StormBreaker Plus series’ dry-glazed frame geometry. Call (561) 354-3861 to schedule your measured survey. The document is yours to keep, and the price we write on it does not change.
How ES Windows Products Fail - and How We Fix Them
- Impact Plus series - seal failure in arched tops. The thermal break in the Impact Plus thermal-staked frame can separate at the radius point of factory-built arches, especially where the West Palm Beach sun loads the southern exposure daily. We see this most often in El Cid and Flamingo Park homes with 1980s-era openings retrofitted to ES Windows arches. Our fix: we pull the sash, document the thermal break gap with a photo record you receive, and replace with OEM-spec frame sections rather than field-bending standard stock, which voids the impact certification.
- StormBreaker Plus series - corner key loosening in geometric sashes. The dry-glazed StormBreaker Plus uses a snap-in corner key that loosens under cyclic wind pressure when the opening exceeds 60 inches on any side. In West Palm Beach, that means every named storm season. We replace with factory-corner-keyed sashes or, where the opening geometry demands it, specify the wet-glazed Impact Plus alternative at the survey stage.
- Custom circle windows - IG unit fogging from capillary tube migration. ES Windows ships custom circles with breather tubes to accommodate altitude changes during freight. If the tube isn’t seated and sealed at installation, West Palm Beach humidity migrates into the airspace within 18 months. We check tube placement with a borescope during survey and re-spec the IG with a permanent seal if the tube shows migration.
- Oversized Impact Plus units - sill track deflection on spans over 96 inches. The reinforced sill in ES Windows’ oversized line requires a specific shim pattern at 16-inch centers. Miss this and the sash drifts, chewing the polyamide rollers. We measure the rough opening to 1/16 inch, specify the shim map in writing, and leave the photo record showing the pattern before the frame is set.
- Geometric combination units - glazing bead hardening in coastal exposure. The PVC glazing bead on older ES Windows custom assemblies loses pliability after 7-10 years of salt-air exposure. We stock the OEM bead profile but also specify the upgraded TPV compound where the opening faces the Intracoastal or is within three blocks of open water - a distinction we make at survey, not after the install.
Our ES Windows Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman or a verified crew member arrives uniformed with license number visible, measures the rough opening and the existing frame to 1/16 inch, and notes wall plane deviation and sill level. You keep the survey document.
- 2
Series diagnosis. We identify the existing ES Windows series from frame profile, stamp, or glass edge detail, then determine whether OEM replacement sashes, factory-custom new construction, or a quality aftermarket solution fits the opening and your specification.
- 3
Written scope and price. The quote specifies every line item - frame, sash, glass package, hardware, sealant, and labor - with no category labeled “miscellaneous.” Haven Clause 1: the measurement and the quote are the same document.
- 4
Order and staging. For custom ES Windows geometries, we verify the shop drawing against our field measurements before the factory releases to production. You receive a copy of the approval.
- 5
Install and test. Crew installs per ES Windows’ impact-certification requirements, shims to our written map, and tests every operable sash for uniform contact pressure. Photo record is uploaded before we leave.
- 6
365-Day Done Right Promise. If the sash drifts, the seal fails, or the hardware binds within one year, we return and make it right. The promise is written into the Haven Standard, not offered as a courtesy.

| Scenario | Typical Range |
|---|---|
| Standard geometric sash replacement (trapezoid, triangle, circle under 48″) | $890 - $1,450 |
| Arched top replacement, Impact Plus series, laminated glass | $1,200 - $2,100 |
| Oversized custom unit, StormBreaker Plus or Impact Plus, over 72″ span | $2,800 - $4,600 |
| Full-frame custom geometric install, including rough-opening correction | $3,500 - $6,200 |
| IG unit replacement only, custom shape, with seal upgrade | $650 - $1,100 |
What moves the price: glass package (laminated impact vs. insulated laminated), frame depth (2-inch vs. 2.5-inch for structural ratings), and whether the rough opening needs reframing for plumb. We also carry PGT, CGI, CWS, and ECO Window Systems lines, so if an ES Windows custom unit doesn’t fit the performance tier or budget, we specify the alternative in writing rather than upsell.

Why West Palm Beach Homeowners Call Sightline Windows & Doors West Palm Beach for ES Windows Work

We’ve installed and serviced 18,000+ openings since 2012, every one with a written price before work started and a documented photo record when finished. Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. Calls are answered by a live person, 24/7, not a voicemail queue.
Sonia Raman learned frame systems and glazing tolerances at Los Angeles Trade-Technical College before spending fifteen years measuring and installing in South Florida, with regular jobs along Flagler Drive and throughout the surrounding neighborhoods. She is known for catching clearance and rough-opening problems before they become change orders. That same precision governs every ES Windows custom and geometric job we take in West Palm Beach.
Our eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - are specified by what the opening requires, not by what is in stock.
FAQs
Using an independent service provider does not automatically void an ES Windows warranty, but warranty coverage on custom geometries is limited to factory defects in material or workmanship for the original purchaser. We document every part source and procedure so you have evidence if a defect claim arises. For warranty-safe practices on impact-rated units, we use OEM-spec frame sections and factory corner keys rather than field modifications. Call (561) 354-3861 and we will review your warranty status at no charge.
Standard custom geometries from ES Windows typically ship 8-14 weeks after shop drawing approval, with oversized or specialty-laminated units running toward the longer end. We verify the shop drawing against our field measurements before releasing to production, which adds 3-5 days upfront but eliminates the change order that comes from a mismatched radius or incorrect sightline dimension. Call (561) 354-3861 to schedule survey and we will give you a firm production timeline for your specific opening.
ES Windows maintains profile dies for discontinued series longer than most manufacturers, but glass packages and hardware often change. We measure the existing frame profile, sightline dimension, and glazing pocket depth, then cross-reference against current ES Windows stock or specify a compatible unit from PGT, CGI, CWS, or ECO Window Systems if the original is unavailable. The written quote states exactly which series we are matching and where the specification differs. Call (561) 354-3861 for a free second opinion on any existing estimate.
If the frame is square, the hardware operates smoothly, and the fogging is isolated to the IG unit, replacement of the sealed glass package is the correct repair. If the frame shows thermal break separation, corner key loosening, or sill track deflection, we recommend full sash or frame replacement and state both options in writing with their respective prices and expected service life. Call (561) 354-3861 for a measured survey that gives you the real condition of the opening.
We stock common glazing bead profiles, corner keys, and hardware for the Impact Plus and StormBreaker Plus series, plus sealants rated for South Florida exposure. Custom sashes, IG units, and oversized frames are ordered to specification after survey approval. For emergency board-up on a failed custom unit, we can secure the opening with temporary protection same day while the permanent unit is in production. Call (561) 354-3861 to discuss your timeline.
