Single & Double Hung Windows in Lantana, FL

Single and double hung windows are the most common window type in Lantana homes, and replacing them is one of the most straightforward upgrades a homeowner can make – when the measurements and the written price come first. At Sightline Windows & Doors, every Window Installation starts with a measured survey you keep, and the written quote cannot differ from that document. If you’d like to talk through what your openings need, call us at (561) 461-2062 – a live person picks up, any time.

Single hung windows have one fixed sash at the top and one operable sash that slides up from the bottom. Double hung windows operate the same way except both sashes move, which makes them easier to clean from inside and allows more control over airflow. In Lantana’s climate – where summer heat, salt air off the Atlantic, and afternoon thunderstorm moisture are all working against your frames simultaneously – the choice between these two styles, and whether you need Awning & Hopper Windows or another product line behind them, matters more than most homeowners realize when they first start looking.

Sightline has installed and replaced more than 18,000 windows and doors since 2012, every one of them with a written price before a tool was lifted and a documented photo record when the job finished. Our Window Installation in Lantana practice covers the full range of opening types, but single and double hung replacements are where we do a significant portion of that work – particularly in the older ranch-style and mid-century homes that line the streets between Hypoluxo Road and the Intracoastal.

When You Need Single & Double Hung Window Replacement

• Sashes that stick, bind, or won’t stay open. In Lantana, wood frames absorb moisture during the rainy season (May through October) and swell against the jamb. If you’re propping a window open with a stick, the balance mechanism or the frame itself has failed.
• Visible condensation between panes. When the seal on an insulated glass unit fails, moisture gets trapped in the airspace. The glazing is no longer performing as designed, and no amount of cleaning fixes it – the glass unit needs replacing.
• Drafts or humidity infiltration around the frame. Lantana homes within a few blocks of the Intracoastal see salt-laden air work into deteriorating weatherstripping and frame corners. A measurable pressure difference around the sash is a sign the unit’s air sealing has failed.
• Single-pane glass that predates current Florida Building Code requirements. If your home was built before the late 1990s and the windows haven’t been touched since, you’re likely looking at single-pane frames that don’t meet current energy or impact standards – and your utility bills probably reflect it.
• Paint or caulk used to seal a window shut. This shows up often in older Lantana rentals that have been through multiple owners. A window sealed shut for “convenience” is a ventilation problem and, in a bedroom, a fire egress issue.
• Hardware or tilt-wash latches that no longer function. Broken tilt mechanisms on double hung windows aren’t just an annoyance – when a sash can’t be secured in the closed position, the window becomes a gap in your home’s envelope.

Our Single & Double Hung Window Process

1. Measured Survey – the document you keep. We measure every opening by sightline dimensions: the clear daylight opening, the rough frame, and the existing jamb depth. Those numbers go into the written survey the customer receives. Haven Clause 1 (Have It In Writing) means the quote that follows cannot deviate from that document – you will never see a number on the invoice that wasn’t on the survey.
2. Product Specification by Opening. We pull from eight verified manufacturer lines and specify by what the opening requires. For Lantana homes, that often means recommending an impact-rated double hung from CGI or CWS that meets Miami-Dade Notice of Acceptance (NOA) requirements – relevant because Palm Beach County enforces high-velocity hurricane zone standards for coastal municipalities. We name the product, the model, the glass package, and the U-factor and SHGC values in writing before you commit to anything.
3. Permit Coordination. Hung window replacements in Lantana require a permit through Palm Beach County Building Division when the work changes the frame (a full-frame replacement). Sightline handles permit application and inspection scheduling as part of the documented scope – it’s on the written price, not added later.
4. Frame Removal and Opening Prep. Our background-checked, uniformed technicians remove the existing frame, check the rough opening for rot, damaged sill plate, or compromised stucco at the perimeter, and photograph what they find. If there’s deterioration that affects the scope, you see the photos and the revised written scope before any additional work proceeds. Haven Clause 4 (Evidence on Every Job) is not optional.
5. Installation to Manufacturer Spec and Florida Building Code. The new frame is set, shimmed, and anchored to the structural opening per the product’s NOA installation instructions. Flashing and sealant are applied in the sequence specified by the manufacturer – sequence matters here because sealant applied in the wrong order traps water rather than directing it away from the opening.
6. Final Documentation and 365-Day Done Right Promise. Every visit ends with a photo record uploaded to your job file. We test both sashes for smooth operation, verify the tilt-wash latches engage correctly, and confirm the sightline gap is uniform. The 365-Day Done Right Promise – written into the Haven Standard – covers the installation workmanship for a full year. If it’s not right, we come back and make it right, no argument required.

Single & Double Hung Window Pricing in Lantana

Single and double hung window replacement in Lantana typically runs between $420 and $1,100 per window installed, depending on glass package, impact rating, frame material, and opening size. That range covers the most common scenarios we see in Lantana: standard residential openings in existing stucco frames, replacing aluminum single-pane units with modern insulated or impact-rated double hungs.

What Moves the Number

• Impact vs. non-impact glass. Impact-rated glazing – laminated glass with a structural interlayer meeting Miami-Dade NOA – adds cost over standard insulated units. In Lantana, homes within the coastal construction setback or in flood zones A or AE often have HOA or lending requirements that specify impact product regardless of personal preference.
• Insert vs. full-frame replacement. An insert replacement drops a new unit into the existing frame, preserving the surrounding stucco and interior trim. It’s faster and less expensive when the existing frame is structurally sound. Full-frame replacement – removing everything down to the rough opening – costs more but is the right call when the frame has rot, the sill is compromised, or you’re changing the window’s size or configuration.
• Frame material. Vinyl is the most common specification in Lantana’s price range and performs well in the salt-air environment. Aluminum frames cost more and require a thermal break to meet Florida’s energy code in most residential applications. We name the material and explain the trade-off in the written survey.
• Glass performance values. Florida’s residential energy code (Florida Building Code, Energy, 7th Edition) sets maximum SHGC and U-factor thresholds for the climate zone. Lantana falls in Florida Climate Zone 1 – the hottest designation – which means the code ceiling is stricter than much of the country. Products from ES Windows and ECO Window Systems both carry glass packages engineered for Zone 1 compliance; we specify the values on the written survey so you’re not guessing at inspection.
• Condition of the rough opening. Wood rot at the sill, damaged lintel, or compromised stucco at the perimeter all require remediation before a new frame can be set correctly. We photograph everything we find, and any scope change comes with a written revision before the work proceeds.

The written price covers labor, product, standard flashing and sealant, permit coordination where required, and the 365-Day Done Right Promise. There are no line items that appear later.

FAQs – Single & Double Hung Windows in Lantana

What is the difference between a single hung and a double hung window, and which is better for Lantana?

A single hung window has one fixed upper sash and one sash that slides up from the bottom; a double hung has two operable sashes that move independently. For most Lantana homes, a double hung is the more practical choice because both sashes tilt inward for cleaning – useful when you’re dealing with salt film and storm debris on exterior glass that you can’t safely reach from outside. The cost difference between the two styles is usually modest (roughly $40-$80 per window at the product level), and the cleaning access alone justifies it for two-story homes or any window that backs up to a screened enclosure. We’ll note which configuration your opening supports in the written survey.

Do hung window replacements in Lantana require a permit?

Full-frame replacements – where the existing frame is removed and a new one is set into the rough opening – require a permit through Palm Beach County Building Division. Insert replacements (new unit into an existing frame) may or may not require a permit depending on scope; we confirm the requirement during the measured survey and include permit coordination in the written price when it applies. Working without a permit where one is required creates problems at resale and can void manufacturer warranties on impact product, so Sightline does not skip this step. Call (561) 461-2062 and we’ll walk you through what your specific replacement requires.

How long does a hung window replacement take in Lantana?

A standard insert replacement on a single residential opening takes two to three hours from arrival to cleanup. A full-frame replacement on the same opening runs three to five hours, longer if the rough opening needs remediation. A whole-house project – eight to twelve windows, which is common in Lantana’s mid-century ranch stock – typically runs one to two days depending on access, frame condition, and permit inspection scheduling. We give you the project timeline in the written scope, not a verbal estimate on the phone.

Can I replace just one window, or does Sightline require a minimum project size?

We replace single windows. There is no minimum count. The written price, the measured survey, and the 365-Day Done Right Promise apply to a single-window job the same way they apply to a full-house replacement. That said, if you’re considering Window Installation Near Me in Lantana, FL for multiple windows, it’s worth having them measured at the same time – the survey is free, and you’ll have documented dimensions and written pricing for every opening when you’re ready to sequence the work. Call (561) 461-2062 to schedule.

Why Sightline for Hung Windows in Lantana

The range of homes in Lantana – from the smaller concrete block residences near Lantana Road to the newer construction backing up to Lake Osborne – means hung window specifications aren’t one-size fits all. A home built in 1968 with original aluminum frames in stucco has different rough-opening conditions than a 2005 construction with vinyl frames and a different flashing detail. We measure the actual opening, specify the product that fits what we found – whether that’s standard hungs or 3-Panel Sliding (3-Lite Roller) Windows – and give you the written numbers before anything is ordered or removed.

Sonia Raman leads Sightline Windows & Doors and has built the company’s operating standards around a single governing document: the Haven Standard, which has applied to every one of our 18,000+ openings since 2012. Haven Clause 3 (Verified Crews) means the technician who arrives at your door has been background-checked, arrives in a Sightline uniform, and is identified by license number before the job starts. The Free Second Opinion on any written estimate means you can bring us a competitor’s quote on your Lantana project and we will review it at no charge – no pressure, no obligation.
