Single & Double Hung Windows in Miami, FL

Single & Double Hung Windows in Miami, FL

Single hung and double hung windows are the most common window styles in Miami homes, and for good reason. A single hung window has a fixed top sash and a bottom sash that slides up to open. A double hung window lets both sashes move, so you can open the top, the bottom, or both at once. Most window installation projects for single and double hung replacements in Miami run between $450 and $1,100 per window installed, depending on size, frame material, glass package, and whether you’re in a condo high-rise or a single-story ranch in Kendall. If your current windows are original to a house built before 1995, there’s a strong chance you’re losing cooled air through them every single day.

Westlight Windows Miami installs single and double hung windows from PGT, CGI, CWS, and ViewLux, among the eight manufacturer lines we carry. Owen Satterfield leads our team, and every job gets the same written-price-before-work-starts treatment that has defined our company since 2009. If you’re weighing repair against replacement or just want a straight answer on what new hung windows cost, call us at (850) 753-2730. A real person picks up, day or night.

When You Need Single & Double Hung Windows

Not every window problem calls for a full replacement, but when the problem involves the sash, the frame, or the seal, hung windows rarely heal themselves. Here are the situations we see most often in Miami homes:

• The sash won’t stay up. In a single or double hung window, the sash rides on spring balances or block-and-tackle systems inside the frame. Miami humidity accelerates wear on these parts, and once the balance fails, the sash drops hard when you let go. That’s a finger hazard for anyone in the house, especially kids.
• You can feel air moving around the window even when it’s closed. Hung windows rely on weatherstripping along the meeting rail and the side jambs. Years of sun exposure in places like Pinecrest or Coral Gables breaks that stripping down, and conditioned air leaks out. You’ll notice it most in August when the AC runs constantly.
• Condensation between the glass panes. If you see fog or water droplets inside the glass itself, the seal has failed. The insulating gas is gone and the glass is now two panes with damp air between them. No cleaning fixes that; the sash or the whole window needs replacement.
• The frame shows rot, especially at the bottom corners. This is common in older wood-frame hung windows throughout Coconut Grove and the Roads, where rain blows sideways in summer storms and sits on the sill. Soft wood means the structure is compromised and water is getting into the wall.
• Opening or closing the window takes two hands and a lot of muscle. Warped tracks, swollen wood, or bent hardware makes operation a fight. In a double hung, both sashes should glide with one hand. If they don’t, the hardware is worn past adjustment.
• You need impact-rated glass to meet current Miami-Dade code. If you’re renovating after a storm or bringing an older home up to the county’s High Velocity Hurricane Zone standards, the windows are almost always the first item on the list. PGT and CGI impact hung windows are made for exactly this.

If any of these sound familiar, the next step is a straightforward assessment. We’ll tell you whether the window can be repaired or whether replacement makes more financial sense, and we’ll put that recommendation in writing before any work starts.

Our Single & Double Hung Windows Process

Here is exactly how a hung window replacement works with Westlight Windows Miami, from first call to final walkthrough:

1. You call and talk to a person. Our phone line at (850) 753-2730 is staffed 24/7 by a real human, not a voicemail robot. Tell us what’s happening with your windows. We’ll ask about the age of the home, the number of windows involved, and whether you’ve had any water intrusion or seal failures.
2. We measure and assess in person. A background-checked, uniformed technician visits your home at a scheduled time. We measure the existing openings, check the frames for rot or squareness, and look at what’s happening with the surrounding stucco or siding. This step matters because hung windows are sized to the opening; an eighth of an inch matters.
3. You get a written price before any work starts. This is a core part of the Kingswell Guarantee. The price we put on paper is the price you pay. No revised invoice at the door, no “we discovered something” upcharge. If our measurement reveals a problem that changes the scope, we stop and talk to you first.
4. You choose your product from real options. We’ll walk you through what makes sense for your home and budget. For a high-rise condo in Brickell, that might mean a ViewLux or CWS impact-rated hung window with a slim frame profile. For a single-family home in Kendall or Palmetto Bay, a PGT single hung with low-e glass (a thin coating that reflects heat back out in summer) often delivers the best value. The right product gets matched to the job, never the other way around.
5. We install, working from the inside wherever possible. Our crew sets the new window in the opening, shims it level and square, anchors it per Miami-Dade requirements, insulates the gap, and seals the exterior perimeter. We work clean: drop cloths inside, no debris left in the yard, the job site tidier than when we arrived.
6. You receive your written guarantee. Before we leave, we hand you the warranty paperwork and explain the 365-Day Done Right Promise: if the work is not right within the guarantee period, we return and correct it at no charge. No negotiating, no fine print. That’s The Kingswell Way: say the price before the work; show up in the window we gave; leave the place cleaner than we found it; put the guarantee in writing; and come back if it fails.

Single & Double Hung Windows Pricing in Miami

Most single and double hung window replacements in Miami fall into these ranges, installed:

• Standard single hung, vinyl frame, clear glass: $450 to $700 per window
• Standard double hung, vinyl frame, low-e glass: $600 to $900 per window
• Impact-rated single or double hung (Miami-Dade approved): $850 to $1,500 per window
• High-rise or hard-access installations: add $150 to $400 per window depending on floor height and access limitations

Several factors move the price within those ranges. Window size is the biggest one: a 24-by-36-inch bathroom window is a different project from a 60-by-60-inch picture replacement in a living room. Frame material matters too. Vinyl is the most affordable and holds up well in Miami’s humidity. Aluminum is common in mid-century homes and condos, though it conducts heat more unless it has a thermal break. Impact glass meeting Miami-Dade High Velocity Hurricane Zone standards costs more than standard glass, and in many parts of the county, it’s required for any new installation.

The age and condition of the existing frames also plays a role. If the old frames are square and the surrounding stucco is intact, the job is straightforward. If we find rot or termite damage inside the wall, the scope changes and so does the price, which is why we never quote a final number sight-unseen.

Every customer receives a written price before any work begins. Call (850) 753-2730 to schedule a free in-home assessment for Window Installation Near Me in Miami, FL and get your exact number. There’s no obligation and no pressure.

Frequently Asked Questions About Single & Double Hung Windows

How much does it cost to replace a single hung window in Miami?

A standard vinyl single hung window replacement in Miami runs $450 to $700 per window installed, while impact-rated single hung windows for Miami-Dade compliance typically run $850 to $1,500 per window. The exact price depends on window size, frame material, accessibility, and whether you need impact glass. Call (850) 753-2730 and we’ll give you an exact written quote after measuring, free of charge.

What is the difference between single hung and double hung windows?

A single hung window has a fixed top sash and only the bottom sash opens, while a double hung window lets both the top and bottom sashes slide, which gives you better airflow and easier cleaning from inside, unlike 3-Panel Sliding (3-Lite Roller) Windows which operate on a different mechanism. Double hung windows cost about $100 to $200 more per window than single hung of the same size and material. In Miami’s climate, the ability to open the top sash on a double hung lets hot air escape high while cooler air comes in low, which actually improves cross-ventilation in older homes without whole-house fans.

Are double hung windows worth the extra cost?

For most Miami homeowners, yes, especially in two-story homes where cleaning an upstairs window from outside is awkward or unsafe. Double hung windows let you tilt both sashes inward for cleaning from inside the room. The extra cost is modest, typically $100 to $200 per window, and the added ventilation benefit is real in a hot climate. If budget is the deciding factor, a single hung with good low-e glass still outperforms an old builder-grade window every time.

Do I need impact windows in Miami? Do you install them?

Per Miami-Dade County code, any new or replacement window installed in a High Velocity Hurricane Zone must be impact-rated or protected by an approved shutter system, a standard that also applies to Awning & Hopper Windows. Yes, we install impact-rated single and double hung windows from PGT, CGI, and CWS, all of which carry Miami-Dade product approvals. The glass is laminated and the frames are reinforced to withstand windborne debris, and in many homes, the impact windows also drop your windstorm insurance premium, which often offsets part of the upfront cost over time.

How long does it take to install single and double hung windows in Miami?

A typical single and double hung window replacement takes 1 to 2 days for 3 to 6 windows, including removal of the old units, frame prep, installation, sealing, and cleanup. Larger whole-home projects of 10 or more windows usually run 3 to 5 working days. We give you a committed arrival window before the job and we show up inside that window, which our customers tell us is a rare thing in this business.
