AfterSingle & Double Hung Windows in Weston, FL
Single and double hung windows are the most common window type in Weston homes, and they are also among the most frequently replaced – because when the hardware wears out, the balance system fails, or the glazing no longer meets Florida’s impact code, the fix is a full unit swap, not a patch. Sightline Windows & Doors Weston provides Window Installation and replacement for single and double hung windows across Weston with a written price before any work starts, a documented photo record when the job is finished, and the 365-Day Done Right Promise stamped on every opening we touch.
We’ve handled this specific window type in everything from the ranch-style builds in Sector 6 near Weston Town Center to the two-story lake-facing homes in The Ridges and Windmill Ranch Estates – where the upper sash sees direct south and west sun for most of the afternoon and the solar heat gain coefficient of the glazing unit matters as much as the frame color. For homeowners searching for Window Installation Near Me in Weston, FL, we offer local service with fast response times. If you’d like a written number before committing to anything, call (754) 812-9260. A live person answers, any hour.
This page covers how single and double hung windows work, when replacement makes more sense than repair, what the installation looks like from survey to sign-off, and what Weston homeowners typically pay. For the full picture of what we do with every window opening in Weston, visit our Window Installation in Weston page.
Single vs. Double Hung: What the Difference Actually Means
A single hung window has one operable sash – the bottom one moves up; the top is fixed. A double hung window has two operable sashes, so you can open the top, the bottom, or tilt both inward for cleaning from inside the room. In Florida’s climate, that second operable sash is more than a convenience: it lets warm air escape from the top while drawing cooler air through the bottom, which reduces the cooling load on days when the outdoor temperature is bearable but the humidity is not.
The trade-off is mechanical complexity. Double hung windows have twice the balance hardware – the spring or block-and-tackle system that holds each sash in position – and that hardware is the most common failure point in older Weston window stock. When a balance fails, the sash drops, won’t stay open, or begins to rack slightly in the frame, creating air infiltration around the weatherstrip. On a unit that’s already 15 or 20 years old, replacing the balance is often a short-term fix on a frame that’s already past its service life.
For impact compliance – which applies to every window in Weston under the Florida Building Code – both single and double hung configurations are available in impact-rated units. The laminated glass assembly and the reinforced meeting rail are what carry the impact rating, not the operable configuration. We specify the right unit for the opening based on the measured survey, not on what happens to be in stock.
When You Need Single & Double Hung Windows
- The sash won’t stay open, or drops on its own. This is a failed balance system. In Weston’s humidity, metal balance hardware corrodes faster than the manufacturer’s rated service life suggests – particularly in homes that run the AC hard and cycle the windows seasonally. When both sashes on a double hung unit have failed balances, the cost of parts and labor typically approaches the cost of a new unit from a line like ES Windows or ECO Window Systems, both of which carry Florida Product Approval for this configuration.
- The meeting rail no longer locks flush. On a double hung window, the point where the upper and lower sash meet in the middle – the meeting rail – is the primary air and water seal when the window is closed. If the sashes no longer align and the lock won’t seat, you’re losing conditioned air and creating a water intrusion path every time Weston gets a band of rain ahead of a front.
- The frame or sash shows visible rot, warping, or delamination. Wood and older aluminum frames in Weston’s salt-adjacent air degrade at the corners first. Once the frame is no longer square, the glazing seal fails and so does the impact rating. This is not a caulk job; it is a replacement.
- Your windows were installed before 2002 and have not been replaced. Florida’s current impact requirements under FBC Section 1609 were substantially tightened after Hurricane Andrew and again after the 2004 season. A window installed before those code cycles may carry no impact rating at all, or a rating that no longer satisfies current Broward County permit requirements. We see this regularly in the older sections of Weston near Bonaventure.
- Your energy bills are climbing without an obvious explanation. Single and double hung windows account for a large share of a home’s solar heat gain in a west or south-facing elevation. If the low-E coating on the glass has degraded or was never specified correctly, the SHGC (solar heat gain coefficient) is working against your AC. A replacement unit with a documented SHGC of 0.25 or lower – standard on current CWS impact product – makes a measurable difference on a Weston home that faces the afternoon sun.
- You’re listing the property or refinancing, and the windows are flagged. Broward County inspectors and lenders increasingly flag non-impact windows in the wind-borne debris zone. A documented replacement with a permitted, inspected installation resolves the flag and leaves a paper trail the buyer’s attorney can read.

AfterOur Single & Double Hung Windows Process
- Measured Survey – the document you keep. A Sightline technician measures every opening to be replaced: rough opening dimensions, existing frame depth, sill condition, and the wall assembly around the frame. We note the compass orientation of each window (south and west exposures in Weston matter for SHGC specification), the existing product, and any signs of water intrusion or frame damage. You receive a copy of this document. It is not a marketing piece – it is the technical record of your openings.
- Written Scope and Price – same document, no second invoice. The measured survey becomes the written price. The dimensions we measured are the dimensions on the quote. The product line, the series, the glass package, and the labor are each listed as a line item. Under Haven Clause 1 – Have It In Writing – this document cannot change without your written authorization. There is no estimate that becomes something different at invoice time.
- Permit Pulled Before Scheduling. Weston window replacements in the wind-borne debris region require a Broward County permit. We pull it, we track it, and we schedule the installation date after the permit is active. We do not begin work on a window opening that isn’t permitted – full stop. The permit number goes on the written scope.
- Installation by Verified Crew. Under Haven Clause 3 – Verified Crews – every technician who arrives at your home is background-checked, uniformed, and identified by license number before the job begins. The removal of the existing unit, the preparation of the rough opening, the installation of the new frame, the glazing, the weatherstrip, and the hardware are all completed in a single scheduled visit for most standard single and double hung replacements. We protect interior finishes with drop cloths and remove all debris from the site.
- Documented Photo Record. Before we leave, every opening gets a photo record: the rough opening before installation, the installed frame, the glazing detail, the hardware, and the exterior finish. This is Haven Clause 4 – Evidence on Every Job. The photos go into your job file and are available to you. If there is ever a question about the installation – from your insurance carrier, a future buyer, or a Broward County inspector – the record exists.
- Inspection Sign-Off and 365-Day Promise. We coordinate the final inspection with Broward County. When the inspector signs off, we send you the closed permit documentation. The 365-Day Done Right Promise begins at that date: if anything about the installation is not right within the first year, we make it right – in writing, not as a verbal assurance.
Single & Double Hung Windows Pricing in Weston
Single and double hung window replacement in Weston typically runs between $480 and $1,200 per opening for a standard residential installation, including product, labor, and permit. The range is wide because the variables are real: the size of the opening, the product line specified, the glass package selected, and the condition of the existing frame and surrounding wall assembly all shift the number.
| Scope | Typical Range per Opening | What Drives It |
|---|---|---|
| Standard single hung, builder-grade opening, impact-rated | $480 – $650 | Common rough opening size, no frame repairs needed |
| Double hung, mid-range series, impact-rated with low-E | $620 – $850 | Second operable sash, balance hardware, low-E glass package |
| Double hung, performance series, documented SHGC spec | $800 – $1,100 | South or west exposure, higher-grade glass, specified U-factor |
| Any opening with frame damage, rot, or non-standard rough opening | Add $120 – $300 | Frame repair, buck work, or custom-sized unit required |
| Permit (Broward County, standard residential) | Included in written scope | Not a separate line-item surprise |
Multi-window projects in Weston – where a homeowner is replacing six or more openings in a single permit pull – typically see a lower per-opening number because the mobilization and permit costs are distributed across the job. We state the per-opening breakdown and the project total on the same written scope, so you can see exactly where the savings come from.
The written price is always free. Call (754) 812-9260 to schedule a measured survey; there is no charge and no obligation. If you already have a written estimate from another contractor, bring it – we offer a free second opinion on any written quote.
Products We Specify for Single & Double Hung Openings in Weston
We draw from eight manufacturer lines and specify by what the opening requires. For single and double hung replacements in Weston, two lines come up most often. We also install 3-Panel Sliding (3-Lite Roller) Windows for larger openings where a different configuration makes sense.
ES Windows manufactures in Florida and carries Florida Product Approval across a full range of single and double hung configurations. Their Series 2000 and Series 3000 impact hung windows are well-suited to the standard rough openings we see in Weston’s 1990s and 2000s construction, and the documented U-factors and SHGC ratings are on the FPA certificate – not a marketing claim.
CWS (Custom Window Systems, also Florida-manufactured) is a strong fit for projects where the opening is non-standard or where the homeowner wants a documented SHGC below 0.25 for a south or west-facing exposure. The CWS hung window line carries impact rating and energy performance certification that satisfies both the FBC and the requirements of Broward County’s current building department.
We do not steer product selection by margin. The survey tells us what the opening needs; the product lines we carry fill that need. The written scope names the product, the series, and the Florida Product Approval number so you can look it up yourself before signing anything.
Weston-Specific Considerations
Weston is fully inside Broward County’s wind-borne debris region, which means every window replacement requires an impact-rated unit and a pulled permit – no exceptions under current FBC requirements. This is not optional compliance; it affects your homeowner’s insurance, your resale disclosure obligations, and the structural envelope of the home.
The community’s development pattern also creates some specific conditions we account for at the survey stage. Homes in The Ridges and Windmill Ranch Estates frequently have larger openings on the rear elevation facing the water or the preserve, and those openings carry more load in a wind event. Homes in the Sectors – the earlier Weston construction closer to Bonaventure – often have aluminum single hung units that are now 25-plus years old, with frames that have corroded at the corners and glazing that was never impact-rated to current standards. In those homes, we almost always find frame damage that affects the written scope, and we document it in photos before quoting the repair separately rather than folding it into an undisclosed estimate.
Weston’s afternoon heat load is also not trivial. The city’s west-facing elevations – common in the grid-planned Sectors – receive direct sun from roughly 1 p.m. until sunset. A double hung unit with a high SHGC on that exposure is adding measurable cooling load every afternoon. We note the compass orientation in the measured survey and flag it in the product recommendation.
FAQs – Single & Double Hung Windows in Weston
How much does it cost to replace a single hung window in Weston?
A standard impact-rated single hung window replacement in Weston runs between $480 and $650 per opening, including product, labor, and the Broward County permit – when the existing frame is in good condition and the rough opening is a standard size. If the frame has corrosion damage or the opening is non-standard, add $120 to $300 for the additional scope, which we document and price in writing before any work starts. Call (754) 812-9260 for a free measured survey and written price on your specific openings.
Is a double hung window worth the extra cost over a single hung in Florida?
Yes, in most Weston homes, a double hung is worth the additional $100 to $200 per opening. The ability to open the top sash lets heat escape from the upper portion of the room during Weston’s shoulder-season months – March, April, October, November – when the outdoor temperature is comfortable enough to ventilate but the interior still accumulates heat. The cleaning advantage is also real: both sashes tilt inward, so you’re not leaning out of a second-floor window to clean the exterior glass. The balance hardware adds mechanical complexity, but on a new unit with a documented warranty, that’s a deferred concern rather than an immediate one.
Do I need a permit to replace hung windows in Weston?
Yes. Weston falls within Broward County’s wind-borne debris region, and any window replacement requires a permit and an inspection. The installed unit must carry Florida Product Approval for impact resistance. Sightline pulls the permit as part of every installation – it’s included in the written scope, not billed separately. We do not schedule installation until the permit is active, and we coordinate the final inspection and send you the closed permit documentation when it’s signed off. If a contractor offers to replace your windows without pulling a permit, that is an unpermitted installation that creates disclosure and insurance problems when you sell or file a claim.
How do I know if my existing hung windows are impact-rated?
The most reliable way is to look for an etched or printed label in the corner of the glass unit – it will reference the Florida Product Approval number and the impact test standard (typically ASTM E1886/E1996 or TAS 201/202/203). If the glass is clear single-pane with no label, it is almost certainly not impact-rated. If the label is absent but the glass appears laminated (a slight tint or visible interlayer at the edge), we can identify it during the measured survey and check it against the permit records on file with Broward County. Many Weston homes built before 2002 in the Bonaventure-adjacent Sectors have original non-impact windows still in place. We document what we find and price replacement from that point forward – not from an assumption.
Can you match the window style to the rest of the house?
In most cases, yes. The product lines we carry – including CWS and ES Windows – offer hung windows in a range of frame colors and finishes that match or closely approximate what’s already on the home. The exterior profile dimensions are standardized enough that a replacement unit typically sits in the existing rough opening with the same visual footprint. Where the existing windows have a distinctive exterior trim or a custom color, we note that in the measured survey and address it in the written scope before ordering anything. There are no surprises on product appearance when the scope is documented in advance.
