ECO Window Systems Custom & Geometric Windows in West Palm Beach: What to Know First
As an independent ECO Window Systems service provider in West Palm Beach, we measure, fabricate, and install custom and geometric ECO Window Systems units with written pricing delivered before any work begins. Most custom ECO Window Systems orders in West Palm Beach run 4-8 weeks from measured survey to installation, with standard geometric shapes like arches and trapezoids typically moving faster than full custom curved units. Our quotes for ECO Window Systems custom work in West Palm Beach generally fall between $1,200 and $4,500 per opening depending on series, glazing package, and whether impact rating is required.
This page is for West Palm Beach homeowners who already own ECO Window Systems products and need custom or geometric window solutions - arched tops for a Mediterranean gable, trapezoids following a roof pitch, or oversized fixed units that standard catalogs don’t accommodate. If the number isn’t on the page, it isn’t in the price. Call (561) 354-3861 to schedule your free measured survey and written estimate.
How ECO Window Systems Products Fail - and How We Fix Them
- ECO 9000 Series custom fixed units: seal failure in coastal exposure. We’ve replaced the insulated glass in more than a dozen ECO 9000 Series custom fixed units along Flagler Drive where the south-facing exposure and salt-laden air degraded the primary seal faster than the 10-year glazing warranty period. The symptom is a clean fog pattern that doesn’t wipe - the desiccant is saturated. We source OEM replacement IGUs with upgraded warm-edge spacers and document the frame squareness before ordering, because ECO’s 9000 Series frames have minimal adjustment tolerance once fabricated.
- ECO architectural shape windows: corner stress cracks in trapezoid and pentagon units. The mitered corners on ECO’s geometric line carry stress differently than rectangular frames, especially in openings over 48 inches on the long leg. In West Palm Beach, we see this where a trapezoid was ordered to match a 6:12 roof pitch but the rough opening settled after the original install. Our fix is a full remeasure of the rough opening diagonals, then either a corrected geometric fabrication or a custom subframe that carries the load without transferring stress to the glazing pocket.
- ECO impact-rated custom units: laminated glass delamination at the edge bite. ECO’s impact-rated custom units use a polyvinyl butyral interlayer that can separate if the glass edge sits too shallow in the frame - common when a non-impact frame is adapted for impact glazing without sufficient bite depth. We check the existing frame profile against ECO’s impact glazing schedule; if the bite is insufficient, we specify a frame upgrade rather than attempting a glazing-only replacement that will fail again.
- ECO oversized custom openings: sag in horizontal mullions above 72 inches. ECO’s standard mullion reinforcement works for catalog sizes, but custom widths beyond 72 inches often show visible deflection under wind load in West Palm Beach’s exposure C zones. We calculate the mullion moment based on ASCE 7-22 wind pressures for the specific address - not the zip code average - and specify ECO’s heavy-duty mullion kit or a steel-reinforced composite mullion when the standard extrusion won’t pass L/175 deflection limits.
- ECO curved and radius units: sealant adhesion failure at the radius block joint. ECO’s radius window program uses machined radius blocks at the head and sill with straight jambs; the sealant joint between radius and straight segments is the failure point we see most often in West Palm Beach’s humidity and UV exposure. We remove the failed sealant back to clean substrate, prime with ECO-specified adhesion promoter, and apply a backer rod with structural silicone rated for 50% joint movement - not generic caulk, which is what caused the original failure.
Our ECO Window Systems Custom & Geometric Windows Process

- 1
Measured survey with documented photo record. We arrive with the measured survey form the customer keeps. Sonia Raman or a verified crew member records rough opening width, height, diagonal squareness, and wall thickness at three points each. We photograph the existing frame, interior trim condition, and exterior cladding interface. The customer signs the survey; we both have the same numbers.
- 2
Series identification and failure diagnosis. We locate the ECO Window Systems series marking - usually etched in the glass corner or on the frame edge - and cross-reference with ECO’s fabrication manuals to confirm original specifications. For discontinued series, we maintain archived spec sheets from 2012 forward.
- 3
Parts decision: OEM, verified equivalent, or custom fabrication. Available ECO OEM parts ship from their Florida distribution center in 2-3 weeks. For obsolete series or faster turnaround, we source from our verified aftermarket partners with documented performance matching. We note the source on the written quote; no substitution happens without customer approval.
- 4
Fabrication and delivery coordination. Custom ECO Window Systems units are fabricated to our measured survey, not a phone measurement. We verify the fabrication ticket against our survey before release; mismatches are caught at the plant, not at your door.
- 5
Installation, testing, and documentation. The crew installs per ECO’s published installation guidelines with our Haven Standard additions: shimming sequence documented, fastener type and spacing recorded, and operational test of all moving parts. We leave the photo record, the completed measured survey, and the written warranty.
- 6
365-Day Done Right Promise activation. The job is stamped under Haven Clause 5: No surprises. If the operation, seal, or finish isn’t right, we make it right. The promise is written, not verbal.

AfterWhat ECO Window Systems Custom & Geometric Windows Costs in West Palm Beach
| Scenario | Typical Range |
|---|---|
| ECO standard geometric (arch, trapezoid, circle top) - non-impact, standard glazing | $1,200 - $2,400 |
| ECO standard geometric - impact-rated, laminated glass | $2,200 - $3,800 |
| ECO full custom curved or compound radius unit - non-impact | $2,800 - $4,200 |
| ECO full custom curved - impact-rated with design pressure rating | $3,800 - $5,500 |
| Oversized custom fixed unit over 60 sq. ft. with steel-reinforced mullion | $4,000 - $6,500 |
| IGU seal failure replacement in existing ECO custom unit (glass only) | $650 - $1,400 |
What moves the price: impact rating adds 40-60% for the laminated glass and reinforced frame; radius or compound curves add fabrication time and waste factor; oversized units require engineering review and often crane delivery in West Palm Beach’s dense neighborhoods; and any need for structural subframe modification to the rough opening is priced separately and noted on the written quote before work starts.

FAQs
No - as an independent ECO Window Systems service provider, our installation work carries its own workmanship warranty under the Haven Standard, and we use ECO OEM parts or verified equivalents that preserve any remaining manufacturer coverage on the product itself. We document parts provenance on every job so warranty claims are traceable. Call (561) 354-3861 if you need help interpreting your original ECO warranty terms.
Standard geometric shapes from ECO’s current catalog typically arrive in 4-6 weeks; full custom fabrications including curved or compound radius units run 6-10 weeks depending on current plant load. We don’t quote faster than we can verify - the date on the written quote is the date we expect, not the date we hope for. Call (561) 354-3861 to check current lead times for your specific ECO series.
Repair makes sense when the frame is square, the series is still supported, and the failure is isolated to glass, hardware, or sealant - typically $650-$1,800. Full replacement is the better choice when the frame is out of square beyond adjustment, the series is obsolete with no parts path, or you’re upgrading from non-impact to impact-rated. We give you both numbers on the written quote and note which we’d choose for our own property. Call (561) 354-3861 for a free assessment.
Often yes - we maintain archived ECO fabrication records back to 2012 and can reverse-engineer from the existing unit’s sightline dimensions, frame profile, and glazing specification. When ECO no longer supports the profile, we can specify a verified equivalent from PGT, CGI, or ES Windows with matching sightline and performance values, documented on the quote. Call (561) 354-3861 to bring us your existing unit or photos.
They don’t differ - that’s Haven Clause 1. The measured survey you sign is the basis for the written quote, and the written quote is the final invoice unless you change the scope. In fifteen years of measuring in South Florida, including crews working regularly along Flagler Drive, we’ve learned that catching the rough-opening problem before ordering is cheaper than explaining a change order after. Call (561) 354-3861 to schedule your measured survey.
