Single & Double Hung Windows in West Palm Beach, FL

Single and double hung windows are the most common residential window type in West Palm Beach, and replacing them is one of the most straightforward ways to improve a home’s energy performance, storm protection, and day-to-day livability. A single hung window has one fixed sash and one that raises; a double hung has two operable sashes that both slide vertically, which makes cleaning the exterior glass from inside the house possible – a real advantage in the two-story homes that line neighborhoods like SkyBlue Isles and Prospect Park. At Sightline Windows & Doors West Palm Beach, every Window Installation for single and double hung replacement starts with a written price before a tool is lifted, and ends with a documented photo record the customer keeps.

If you have questions about product selection, sizing, or what the job will cost at your specific address, call us at (561) 354-3861 – a live person answers, day or night. Or read through this page first; we’ve tried to put the information you’d actually need before deciding on Window Installation Near Me in West Palm Beach, FL.

This page is part of our broader Window Installation in West Palm Beach service – if you’re replacing a mix of window types across the house, that page covers the full scope.

When You Need Single & Double Hung Windows

• Fogged or moisture-streaked glass between the panes. When the sealed insulating unit fails, condensation forms in the airspace and won’t wipe off. That seal failure is permanent – the glazing unit needs to be replaced, and in most cases it’s more cost-effective to replace the whole window frame at the same time, especially if the frame is older than 15 years.
• Sashes that won’t stay open or won’t lock closed. In West Palm Beach’s older housing stock – particularly the mid-century concrete-block homes in Flamingo Park and Southland Park – original single hung windows often have worn or missing balance springs, making the sash drop the moment you let go. That’s a ventilation problem in summer and a security concern year-round.
• Frames that have swelled, cracked, or allow air to pass around the sash. Wood and aluminum frames both degrade under South Florida’s humidity and salt air. If you can feel warm air moving around the sash on a hot afternoon, the frame-to-wall seal has failed and the window is actively costing you money on the cooling bill.
• Non-impact windows in a wind-borne debris region. West Palm Beach sits in the High-Velocity Hurricane Zone (HVHZ) for portions of the county. If your single or double hung windows are standard float glass with no laminated or tempered rating, they don’t meet current Florida Building Code requirements for new construction – and they won’t protect the home’s envelope during a storm. Replacement with impact-rated units also qualifies most homeowners for a Citizens Insurance discount.
• Buying, selling, or refinancing a home. Home inspectors in Palm Beach County routinely flag non-compliant or deteriorated windows. Replacing single and double hung units before listing – or immediately after purchase – resolves the inspection item with documentation the title company and insurer can verify.
• Excessive solar heat gain through west or south-facing windows. South Florida’s solar angle means west-facing rooms in homes in neighborhoods like El Cid and Northwood Hills can run five to eight degrees warmer than the rest of the house by mid-afternoon. A low-SHGC (Solar Heat Gain Coefficient) double hung in an ES Windows or CWS impact line can cut that differential measurably without changing the look of the opening.

Our Single & Double Hung Windows Process

1. Measured Survey – the document you keep. A uniformed, background-checked Sightline technician arrives at the scheduled time and measures every opening you want to address. We record the rough opening dimensions, the existing frame material, the wall depth, the sill condition, and any deflection or out-of-square reading in the frame. That survey is yours – it’s the first piece of documentation in your file, and Haven Clause 1 (Have it in writing) means the written price we produce cannot differ from what that document shows.
2. Product specification by opening, not by margin. We draw from eight verified manufacturer lines. For a standard single or double hung replacement in West Palm Beach, we typically specify from CWS, ES Windows, or ECO Window Systems depending on the opening’s size, the home’s current Miami-Dade NOA (Notice of Acceptance) requirements, the U-factor target, and the customer’s budget tier. We’ll tell you which product we’re recommending and exactly why – frame depth, glass package, impact rating, color, and hardware finish – before you sign anything.
3. Written price issued before any work starts. The measured survey and the quote are the same document. There is no separate “formal estimate” that arrives later with a different number. If a product lead time will affect your schedule, that’s noted in writing too.
4. Permit pull and product order. Most single and double hung window replacements in West Palm Beach require a building permit through the City of West Palm Beach Building Department, and we pull it. Palm Beach County has specific HVHZ documentation requirements – the product’s Miami-Dade NOA number goes on the permit application, and the inspector will want to see it at rough and final. We handle that paperwork; you don’t.
5. Installation day. The existing sash and frame come out. We inspect the rough opening for water intrusion, rot, or structural issues before the new frame goes in – because what we find at that stage changes the scope, and Haven Clause 5 (No surprises) means we tell you before we proceed, not after. The new window is set, shimmed, and anchored to the structural framing per FBC requirements, then flashed and sealed. Every opening is photographed before and after.
6. Documented photo record and 365-Day Done Right Promise. Before the crew leaves, you have a documented photo record of the completed installation – frame in place, sill conditions, exterior flashing, and hardware function. The 365-Day Done Right Promise is stamped on the job: if it’s not done right, we come back and make it right. That’s Haven Clause 5 written into the contract, not offered verbally at the door.

Single & Double Hung Windows Pricing in West Palm Beach

Single and double hung window replacement in West Palm Beach typically runs between $420 and $1,100 per window installed, depending on size, glass package, impact rating, and frame material. That range covers the most common scenarios we see in Palm Beach County’s residential market. Here’s how the variables break down:

Those figures assume a standard retrofit – meaning the new frame goes into the existing rough opening without structural modification. If the opening has rot, water damage, or requires a structural header repair, we document that finding during the measured survey and price it separately before any work begins. We’ve found water intrusion behind frames in West Palm Beach homes built before 1985 often enough that we check every opening as a matter of course, not as an upsell.

What moves the price up: larger glass area, high-performance glass packages (low U-factor, very low SHGC), specialty hardware or interior trim to match historic millwork, multi-window projects requiring crane or elevated access, and permit complexity in historic districts like El Cid Historic District, where design review sometimes applies.

What holds the price down: multi-window projects (the measured survey and mobilization cost is shared across more openings), straightforward retrofit into sound framing, and standard color selections that don’t require factory custom finishes.

The written price on your survey is the number on your invoice. Call (561) 354-3861 or request a measured survey online – there’s no charge for the estimate, and you keep the document regardless of whether you proceed with us.

FAQs – Single & Double Hung Windows

What’s the difference between a single hung and a double hung window, and which should I choose?

A single hung window has one fixed top sash and one bottom sash that slides up; a double hung has both sashes operable, so the top can come down and the bottom can go up. For most single-story homes in West Palm Beach, a single hung performs identically for ventilation at a slightly lower cost – typically $60 to $120 less per opening at the product level. Double hung is worth the difference if you have second-floor windows you need to clean from inside, or if cross-ventilation in a narrow room benefits from opening both sashes simultaneously, unlike Awning & Hopper Windows which hinge at the top or bottom. We’ll note which configuration makes sense for each opening during the measured survey. Call (561) 354-3861 if you want to talk through the options before the survey.

Do I need a permit to replace single or double hung windows in West Palm Beach?

Yes, in almost every case. The City of West Palm Beach Building Department requires a permit for window replacement when the work involves a structural opening or an impact-rated product requiring a Miami-Dade NOA. West Palm Beach’s location within the HVHZ means that most replacement windows also need a product approval on file with the permit application before the inspector will sign off. Sightline pulls the permit as part of the job – it’s included in the written price, not billed as an add-on after the fact. Unpermitted window replacements can create problems at sale or refinancing, and they void the manufacturer’s warranty on most product lines.

How long does a single or double hung window replacement take?

A straightforward retrofit of a single or double hung window – no frame rot, standard opening dimensions – takes roughly 45 minutes to 90 minutes per opening once the crew is on site, while a 3-Panel Sliding (3-Lite Roller) Windows installation may take longer due to the larger glass area. A whole-house replacement of eight to twelve windows typically runs one full day. Lead time from signed quote to installation day currently runs three to six weeks in the West Palm Beach market, with the permit review window accounting for most of that span. We’ll give you the current lead time in writing when you receive your quote – not as an estimate, as a documented commitment.

Will new impact double hung windows actually lower my insurance premium in West Palm Beach?

For most homeowners insured through Citizens or a standard admitted carrier, yes – replacing non-impact windows with Miami-Dade NOA-compliant impact units qualifies for an Opening Protection credit under Florida’s Uniform Mitigation Verification Inspection (wind mitigation) program. The credit size depends on what percentage of your home’s openings are protected and what your current premium is, but we regularly hear from West Palm Beach customers in neighborhoods like College Park and Grandview Heights that the annual savings offset a meaningful portion of the window cost over five to seven years. The documentation you’ll need for your insurer – the NOA number, the product approval, the permit final – is part of the photo record Sightline provides on every job.

Why Sightline for Single & Double Hung Windows in West Palm Beach

Since 2012, Sightline has installed more than 18,000 windows and doors across South Florida, every one with a written price in the customer’s hand before a single measurement was taken for anything other than the survey. That’s not a marketing position; it’s the Haven Standard applied to every job, including a two-window replacement in a 1960s CBS home in Northwood and a fifteen-window whole-house retrofit in a newer build off Okeechobee Boulevard.

Single and double hung windows look simple. The opening is rectangular, the product is widely manufactured, and the installation sequence is straightforward when the framing is sound. But West Palm Beach’s building stock includes homes where “sound framing” is not what the drywall is hiding. We’ve found corroded aluminum sub-sills, compromised moisture barriers, and out-of-square openings that would have caused a lesser installation to leak at the first hard rain. The measured survey catches those conditions before the product is ordered. Haven Clause 5 – No surprises – means we tell you what we found and what it costs to address it before we proceed.

Our technicians are background-checked and uniformed. The license number is on the page – Haven Clause 3 (Verified Crews) means the person at your door is the person on record. If something isn’t right within 365 days of installation, we come back and make it right. That’s written into your contract, not offered as a courtesy.

We also offer a free second opinion on any written competitor estimate. If you’ve received a quote from another window company, bring it to us. We’ll review the product specification, the scope of work, and the permit language at no charge – and tell you plainly whether the number reflects what the job actually requires.

Sightline is independently owned and operated, and every engagement is governed by the Haven Standard that has shaped how we’ve worked since the beginning.
