New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Hobe Sound pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

ECO Window Systems Window Replacement: The Hobe Sound Owner’s Guide
We stock and install ECO Window Systems-compatible window replacement parts in Hobe Sound, with most hardware and sash assemblies available same-day from our Martin County inventory. A typical installed replacement runs $340-$780 depending on the series, size, and whether the frame requires re-glazing. Most Hobe Sound homeowners discover the failure when a sash won’t stay open, the lock won’t engage, or they feel air movement around a closed window after a storm season.
Which ECO Window Systems Models This Applies To

ECO Window Systems manufactures three residential lines you’ll find in Hobe Sound homes built between 2015 and 2022: the ECO 4000 single-hung series, the ECO 5000 impact-rated line, and the ECO 6000 thermally broken aluminum series. The part you need depends on which generation you own. Early 4000-series units use a 5/8-inch pivot bar; post-2018 production switched to a 3/4-inch bar that looks identical until you measure. Check the etched code in the glass corner: “ECO-4K,” “ECO-5K-IR,” or “ECO-6K-TB” tells us which hardware pack to pull.
We carry both OEM ECO hardware and quality equivalents from C.R. Laurence and Truth Hardware where the specification matches. For impact-rated 5000-series units, we specify OEM balances and keepers - the Miami-Dade HVHZ certification travels with the original part number, and substituting an untested equivalent voids the rating your insurance policy relies on. For non-impact 4000-series sash hardware, the aftermarket equivalent often outlasts the original at half the replacement cost. We’ll show you both options on the written quote, with the spec sheet for each, so you decide before we order.
Before
AfterSigns Your ECO Window Systems Window Replacement Is Failing
- Sash drops or won’t stay open. The coil balance has lost tension. In Hobe Sound’s salt air, the balance shoe corrosion accelerates; we see this first on east-facing windows within seven to nine years of install.
- Lock won’t engage or feels loose. The keeper has shifted or the cam has worn. Thermal expansion in South Florida’s cycling humidity loosens keeper screws faster than inland climates.
- Visible gap when closed, or whistling at the sill. The sash sweep or weatherstrip has compressed past recovery. ECO’s original pile height is 7/32-inch; after five years of UV exposure it mats to 3/32-inch and leaks.
- Condensation between panes. The insulated glass unit seal has failed. This is not a hardware fix - the entire IGU needs replacement, and we measure the sightline to match the spacer color.
- Crank handle spins without moving the sash (casement units). The operator gearbox has stripped. ECO’s early casement operators used a zinc gearbox; we replace with stainless internals that hold up at Peck Lake’s exposure.

What drives the range: size, impact rating, and whether the frame needs re-glazing after disassembly. Our written quote itemizes each line - parts, labor, disposal - and the total you sign is the total on the invoice. Haven Clause 1: the measurement and the quote are the same document. Every replacement carries our 365-Day Done Right Promise; if the balance tension loosens or the lock shifts, we return and correct it at no charge.
DIY or Call Us?
There’s a safe middle ground. You can verify the model code in the glass corner, photograph the failed part, and check that the window is unlocked and unobstructed - we’ve both wasted a trip to a window that was simply locked from the inside. What goes wrong fast: forcing a seized balance shoe risks snapping the pivot bar and converting a $200 repair into a full sash replacement. Impact-rated windows use tempered or laminated glass; if you dislodge the sash without supporting the weight, the drop can spider the pane or damage the frame’s thermal break. The coil springs in ECO balances carry significant tension. We don’t recommend releasing that without the proper winding tool. If you’ve already removed the part, bring it to us - we’ll match it to stock and schedule the install when the replacement arrives. Call (772) 362-5967 to arrange it.
FAQs

Seven to twelve years for non-impact hardware, ten to fifteen for impact-rated assemblies, with salt-front homes on Jupiter Island and along the St. Lucie Inlet seeing the shorter end of that range. The 5000-series impact line holds up better because the hardware is stainless-spec from the factory. Call (772) 362-5967 and we’ll inspect what you have - estimates are free.
Sometimes a balance can be re-tensioned or a keeper re-seated, but we don’t recommend it for ECO hardware - the replacement part is inexpensive enough that the labor to repair often exceeds the cost of new, and the repaired component rarely matches the original cycle rating. We stock the common sizes so you’re not waiting on a special order. Call (772) 362-5967 for an exact quote - estimates are free.
Most single-component replacements take 45 to 90 minutes on site. IGU replacements require two visits: measure and order, then install once the custom unit arrives from ECO’s Miami facility, typically seven to ten business days. We leave a documented photo record of the completed work before we pack up. Call (772) 362-5967 to schedule.
We stock balances, keepers, operators, and weatherstrip for the 4000, 5000, and 6000 series at our Martin County location. IGUs and custom sash assemblies are ordered to the measured sightline. We’re an independent service provider - not affiliated with ECO Window Systems - and we also stock parts for PGT, CGI, and CWS lines. Call (772) 362-5967 to confirm availability for your model.
Sonia Raman built Sightline on a habit she learned measuring rough openings in Miami: check it twice, write it once, and the number on the page is the number on the invoice. Measure it right the first time, and the door closes the way it’s supposed to - every time after that. Her crew has replaced ECO hardware on homes from Gomez Avenue to the waterfront near Peck Lake, and the documentation goes home with the customer on every job.
Ready for a written price before any work starts? Call (772) 362-5967 to schedule your free estimate. We’ll measure the opening, identify your ECO series, and leave you with a line-item quote you can compare - or bring us a competitor’s written estimate and we’ll review it at no charge under our Free Second Opinion policy.
