Why Fort Lauderdale Homeowners Choose ECO Window Systems Construction
We provide Eco Window Systems in Fort Lauderdale construction, repair, and service throughout the area. Our crews handle full-frame replacements, impact-rated retrofits, sash rebuilds, and sliding door service on ECO 5000, 7000, and 9000 series products every week. We are not an authorized ECO Window Systems dealer, and we will say that plainly. What we are is a Fort Lauderdale contractor with seventeen years of salt-air, high-UV, and wind-load experience on these specific windows – and that’s what actually matters when a meeting rail is bowed or a casement crank spins free.

Call (754) 551-2922 for a written diagnosis and price before any work begins.
ECO Window Systems windows are common in Fort Lauderdale for a reason. Their impact-rated lines, particularly the 9000 Series sliding doors, are built to handle Miami-Dade County wind-load requirements. The older 5000 Series single-hungs still show up by the thousands in 1950s ranch homes and mid-century moderns across Coral Ridge, Rio Vista, and Victoria Park. The problem is not the windows themselves, usually. It is what Fort Lauderdale’s climate does to them over a decade or two. Salt air corrodes zinc alloy operator gears. Intense south-facing sun warps vinyl sashes on unprotected elevations. Daily summer thunderstorms find their way through hairline cracks in concrete sills that wick moisture into the wall cavity. Trevor Nash, who runs Penhallow Remodeling Fort Lauderdale, learned the trade at Los Angeles Trade-Technical College before spending two decades running crews across South Florida and providing General Contractor services. Florida – and he will tell you the same thing he tells every homeowner: the window is rarely the whole problem, and claiming it is costs you money.
Why Trust Penhallow Remodeling Fort Lauderdale for Your ECO Window Systems Construction?

We see ECO Window Systems products at least once a week, which means we have pulled apart enough 5000 and 7000 series windows to know exactly what fails, why it fails, and whether it is worth fixing. That familiarity cuts both ways. It means we diagnose faster, but it also means we are not sentimental about recommending a repair when a full replacement is the honest call. Fort Lauderdale’s humidity punishes half-measures. A window that is square and dry can be repaired. A frame that has been breathing salt air through a cracked sill for eight years cannot be, and we will tell you that before you spend a dollar.
We use OEM ECO parts when they still exist for your model. ECO Window Systems has not supported every discontinued series with the same parts availability, and some 2000s-era hardware is simply gone from the manufacturer’s catalog. When that happens, we do not improvise with the cheapest thing on a supply house shelf. For casement operators and sliding door rollers, we use marine-grade stainless aftermarket hardware that actually survives Fort Lauderdale humidity better than the original zinc alloy parts did. The goal is a window that works for another decade, not one that gets us a callback in eighteen months.
Trevor’s background matters here. He spent the better part of two decades swinging a hammer and running crews across South Florida before Penhallow, and he has seen what the wrong fastener does in a humid climate after a few years. The same logic applies to window hardware. A part that works in a dry climate can seize, pit, or shear in Fort Lauderdale. We install as if the window has to survive its second hurricane season, because it does.

Common ECO Window Systems Construction Problems We Fix in Fort Lauderdale
- Alkali-silica reaction cracking in concrete sills on ECO 5000 Series Single-Hungs. This is the one that surprises people. Older ECO 5000 frames in Fort Lauderdale often have concrete sills exposed to decades of rain, and the alkali in the concrete reacts with silica in the aggregate, producing hairline cracks that do not look like much from the outside. Water does not care how thin the crack is. It wicks through, finds the wall cavity, and the next thing you know you are chasing a leak that is not actually coming from the window seal. We repair the sill crack, seal the penetration, and only then address the window itself. In Coral Ridge and Rio Vista, where 1950s homes are common, this is a recurring pattern.
- Stripped operator gears on ECO 7000 Series Casements. The crank turns and the sash does not move, or the crank spins freely with no resistance at all. The culprit is almost always the zinc alloy gear inside the operator housing. Salt-laden air from the Atlantic works its way into the mechanism over years, corrodes the gear teeth, and eventually strips them. It is a small part, but a real repair. We replace the operator with either a new OEM unit or a marine-grade stainless aftermarket one that handles Fort Lauderdale’s air better than the factory part ever did.
- Warped vinyl sashes on south-facing ECO 5000 windows. Vinyl does not like direct afternoon sun in Fort Lauderdale, especially on western and southern elevations with no shade. We regularly see sashes that have bowed enough to create air gaps of up to 1/8 inch at the meeting rail. That gap means drafts, higher cooling bills, and a lock that no longer engages. If the frame is still square and the counterbalance is intact, a sash-only replacement is often the right repair – and a lot less expensive than a full-frame job.
- Failed interlocking seals on ECO 9000 Series Impact Sliding Doors. Condensation between the glass panes on an ECO 9000 door is not normal, and near the ocean it usually shows up within the first five years if the original seal was compromised during installation or a storm event. The interlocking seal between the two glass lites fails, humid air gets pulled into the space between panes, and you get fogging that will not wipe off. Seal repair on an impact-rated door is a specialized job, and we handle it without pretending the whole door needs to be replaced.
- Exterior weatherstripping failure on ECO Architectural Picture Windows. Fixed picture windows do not have moving parts, but they have plenty of perimeter seal. Salt air and UV degrade the vinyl and rubber weatherstripping over time, especially on east-facing elevations that catch the morning sun and the ocean breeze. The window looks fine, but you feel the draft on a breezy afternoon. We replace the exterior gaskets with UV-stable material matched to the original profile.
ECO Window Systems Parts & Our Repair-vs-Replace Approach

We always try OEM ECO Window Systems parts first for windows still under warranty. Balances, locks, weatherstripping, and sash assemblies are the easy calls. OEM keeps the warranty intact and the fit is exact. But ECO has discontinued hardware on several older series, and when the factory part is gone, we do not put a low-grade generic in its place. For casement operators and sliding door rollers, we stock marine-grade stainless aftermarket components that hold up better in Fort Lauderdale’s humidity than the original zinc alloy hardware. It is a genuinely better part, not just a cheaper one.
The repair-versus-replace decision comes down to two things: is the frame square, and is the glass intact. If both are true, we repair. If the frame has racked out of square, or the glass has a compromised seal on a south-facing elevation, full replacement is usually more economical than chasing a repair that will fail again in three years. We will tell you which one you are looking at before we quote anything. Call (754) 551-2922 to get that diagnosis started.
Last month our tech pulled a 2009 ECO 5000 single-hung from a Coral Ridge home where the lower sash had bowed so badly the lock no longer engaged. The homeowner thought they needed a whole new window, but we found the counterbalance intact and the frame square – so we replaced the sash with an OEM ECO replacement unit, re-glazed the glass, and added new weatherstripping for under $900 instead of a $4,500 full-frame job.
Our ECO Window Systems Service Process – Step by Step
- 1
Diagnosis. We inspect the window, the frame, the surrounding sill, and the wall cavity where moisture might be hiding. On a 5000 Series with a leak complaint, we check the concrete sill for ASR cracking before we touch the window itself. On a 7000 Series with a dead crank, we pull the operator cover and check the gear. The diagnosis is written down with a price.
- 2
Repair or replacement. We source OEM parts first, then quality aftermarket where the OEM part is discontinued or genuinely inferior for Fort Lauderdale conditions. Work is done by background-checked, uniformed technicians on a defined schedule.
- 3
Testing. We open, close, lock, and check the seal on every window we touch. Impact-rated installations get checked against the anchoring schedule and weather barrier. We do not leave a window “good enough” – it is tested before we put the tools away.
- 4
The 365-Day Done Right Promise. If the repair fails within a year, we come back and make it right at no charge. That is in writing on every project. If a repair fails twice, the second return visit is free as well. We treat that promise as a fact of the job, not a selling point.

AfterECO Window Systems Products We Service & Install in Fort Lauderdale
We service and install the full ECO Window Systems residential range: the 5000 Series Single-Hung, the 7000 Series Casement, the 9000 Series Impact Sliding Door, and the Architectural Picture Window line. We also handle related construction around these products – window replacement, impact window installation, and roof repair where a leak has migrated from flashing into the window rough opening. We keep common ECO hardware on the truck: balances, lock sets, operator gears, and sash weatherstripping, so a single-trip repair is the norm, not the exception.
We Also Service These Brands
We also provide Eco Window Systems in Hollywood and other nearby areas, so being multi-brand keeps us honest about what actually works. Our broader remodeling work includes KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, and Kohler and Moen fixtures. We are not dependent on one manufacturer’s catalog, which means our advice about your ECO windows is not shaped by what we happen to sell.
FAQs – ECO Window Systems Construction Service in Fort Lauderdale

No. We are an independent ECO Window Systems service provider. We are not affiliated with or authorized by the manufacturer, and we do not claim to be. What we have is field experience on these windows in Fort Lauderdale specifically – which matters more when the question is about a bowed sash on a south-facing 5000 Series in Rio Vista, not a warranty claim to the factory.
Yes, whenever OEM parts are available for your model and still in production. For discontinued ECO hardware, we use marine-grade stainless aftermarket parts that outperform the original zinc alloy components in Fort Lauderdale’s salt-air humidity. We will tell you which one you are getting and why, before we install anything.
Condensation between the panes means the interlocking seal between the two glass lites has failed. The window’s insulating gas escaped, and humid Fort Lauderdale air moved into the space. On a 5000 Series, if the frame is square and the sash is true, the glass unit can often be replaced without a full-frame tear-out. The cost depends on glass size and impact rating. Call (754) 551-2922 for a written diagnosis.
It depends on the frame. Some ECO 7000 casements can accept impact-rated laminated glass and upgraded hardware, but the frame itself must be in good enough condition to hold the heavier glass and the anchoring system required under Miami-Dade County product approval rules. We will inspect the frame and give you a straight answer. If the frame is not up to it, we will tell you before you pay for a retrofit that will not pass inspection.
The operator gear is stripped. ECO casement windows use a zinc alloy gear inside the operator housing, and after years of salt-laden air in Fort Lauderdale, those gear teeth corrode and shear. The good news is it is a contained repair. We replace the operator, not the window. Call (754) 551-2922 and we will get the right operator matched to your exact 7000 series model.
Check the frame first. If it is square, dry, and the glass is intact, repair is usually on the table. If the sill is cracked through, the frame corners have separated, or the glass seal is compromised, full replacement is likely the cheaper option over five years. We will put that judgment in writing with a firm price. Call (754) 551-2922 for a free estimate.
Here are the ranges we quote most often in Fort Lauderdale, based on window size, impact rating, and frame condition:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
Every estimate is a written line-item quote, not a range and not a verbal ballpark. The number we hand you before work starts is the number on the invoice. Call (754) 551-2922 to schedule your free estimate.
Most single-window repairs – sash replacement, operator swap, seal repair – are done in one visit, typically two to four hours. Impact window installation or full-frame replacement on multiple windows takes longer and depends on the size of the job and whether we are pulling permits. We will give you a defined arrival window and a written schedule before we start.
