Single & Double Hung Windows in Three Lakes, FL

Single and double hung windows are the most common window type installed in Three Lakes homes, and window installation is one of the most straightforward projects we do – when the measurements, product selection, and installation sequence are handled correctly. At Sightline Windows & Doors Three Lakes, every single and double hung replacement begins with a measured survey that becomes your written price before a tool is lifted. That document doesn’t change at invoice time. If you’d like to talk through your openings first, call us at (786) 808-5792 – a live person answers, around the clock.

Single hung windows have a fixed upper sash and a movable lower sash. Double hung windows move both sashes independently, which matters for ventilation and for cleaning – both sashes tilt inward on a double hung, so you can clean the exterior glass from inside the room. In Three Lakes, where afternoon thunderstorms arrive fast and humidity is a year-round condition, the choice between single and double hung, the glazing specification, and the frame material all affect long-term performance in ways that aren’t obvious at the showroom level, unlike specialized options such as 3-Panel Sliding (3-Lite Roller) Windows. Our job is to document what your opening requires and match a product to that specification.

This page sits under our Window Installation in Three Lakes service, which covers the full range of window types and opening categories we handle across the area.

When You Need Single & Double Hung Windows

• Sashes that stick, slip, or won’t stay open. Wood and aluminum frames expand and contract through Three Lakes’ wet season. When sash channels warp or balancers fail, the window either won’t open or won’t hold its position – both are functional failures worth addressing before they get worse.
• Visible condensation between the panes. Dual-pane insulating glass units are factory-sealed with an inert gas fill. When the seal fails, moisture enters the cavity and you see fogging that won’t wipe off. That seal cannot be restored; the glass unit needs replacement, and on older frames the cost of resealing versus full replacement usually favors replacement.
• Drafts you can feel at the frame edge. In Three Lakes homes built before 2000, single-pane aluminum windows are common. The frame conducts heat directly – you can feel warm air leaking at the perimeter in summer. That’s not a weatherstripping fix; it’s a window that has reached the end of its useful performance life.
• Hurricane code compliance gaps. Miami-Dade County requires impact-rated glazing or an approved shutter system for openings in the wind-borne debris region. If your home has standard float glass in hung windows and no shutters, you’re not compliant – and a sale, a renovation permit, or a homeowner’s insurance review can surface that gap quickly.
• Failed or missing egress compliance. Florida Building Code specifies minimum clear-opening dimensions for sleeping rooms. Older single hung windows often don’t meet current egress requirements. If you’re renovating a bedroom or adding an accessory dwelling unit in Three Lakes, this needs to be addressed with the window selection, not after.
• Water infiltration at the sill or frame corners. Sill pan failures and compromised frame corners are common in Three Lakes homes that absorbed multiple wet seasons without adequate caulk maintenance. Once water has tracked behind the frame, the damage spreads to the rough opening, the sill plate, and the interior finish – a window replacement and frame repair together, not a caulk job.

Our Single & Double Hung Windows Process

1. Measured survey – your document, not ours. We measure every rough opening, record the frame condition, note the wall assembly (CBS block, wood frame, or hybrid – all three appear in Three Lakes), and document the existing glazing spec. The customer receives a copy of this survey. It is the same document that becomes the written price. Haven Clause 1 of the Haven Standard: the price is in writing before any work starts, and the measurement and the quote are the same document.
2. Product specification by opening requirement. We draw from eight manufacturer lines – for single and double hung work in Three Lakes, we most often specify from CWS, ES Windows, and ECO Window Systems depending on the performance tier, impact rating, and budget. The product recommended is the one the opening requires, not the one with the best margin. We’ll show you the U-factor, Solar Heat Gain Coefficient (SHGC), and impact rating on paper so you can compare specifications across options.
3. Written price before scheduling. Once the survey is complete and the product is specified, you receive a written scope and price. No range, no estimate-subject-to-change, no “we’ll know more once we open the wall.” The number on that document is the number on the invoice.
4. Installation by background-checked, uniformed technicians. Haven Clause 3 – Verified Crews – means the person who arrives at your door in Three Lakes is identified by name and license number before they arrive. Frame removal is sequenced to protect your interior finish; sill pan flashing is installed and inspected before the new frame goes in; shimming and fastener spacing follow Florida Product Approval requirements for the specific product installed.
5. Documented photo record on completion. Every opening is photographed at each stage – frame out, sill pan, frame in, glazing installed, interior and exterior trim complete. Haven Clause 4 – Evidence on Every Job – means you have a visual record of what was done inside the wall, not just what’s visible from the living room.
6. 365-Day Done Right Promise. If anything about the installation is not right within the first year – sash balance, sill seal, frame alignment – we come back and make it right. That promise is written into every job under the Haven Standard. It is not a verbal assurance and it is not subject to interpretation.

Single & Double Hung Windows Pricing in Three Lakes

Single and double hung window replacement in Three Lakes runs between $420 and $1,100 per window, fully installed, for standard residential openings. That range reflects real variation in product tier, glass specification, and opening condition – not a bait-and-switch floor price. Here’s how the range breaks down in practice:

A few factors that move the number up or down in Three Lakes specifically:

• Impact rating requirement. Impact-rated glazing carries a Miami-Dade Notice of Acceptance (NOA) and is tested to the Large Missile Impact standard. The glass itself costs more than standard insulating glass, and the frame system is heavier. If your home is in the wind-borne debris region – which covers most of Three Lakes – impact glass is the right specification regardless of whether you have shutters, and the price difference over the life of the window is smaller than most homeowners expect.
• Frame material. Vinyl frames are the most common specification we install in Three Lakes because they resist the moisture and salt-air exposure this area receives. Aluminum frames are still specified in some applications, particularly where impact performance and narrow sightlines matter more than thermal performance. The price difference between vinyl and aluminum at equivalent performance tiers is typically $40 to $90 per window.
• Opening condition. CBS block construction (common in Three Lakes homes built from the 1960s through the 1990s) holds up well but can have corroded buck frames that need to be replaced before a new window can be set. We document frame condition during the measured survey so the rough opening repair cost is in the written price, not a surprise line item at installation.
• Project size. Multi-window projects that cover an entire home or floor level are priced differently than single-window replacements. If you’re replacing eight or more windows at once, the per-unit installed cost typically comes down. The written survey covers every opening, so the per-window price for each is stated on the same document.

We offer a free second opinion on any written estimate you’ve already received. Bring us a competitor’s quote and we’ll review the scope, the product specification, and the price at no charge – Haven Clause 1 applies to that review as well.

FAQs – Single & Double Hung Windows

What is the difference between single hung and double hung windows, and which is better for Three Lakes?

A single hung window has a fixed upper sash and a lower sash that slides up; a double hung window has two independently movable sashes. In Three Lakes, double hung windows are generally the better specification for two reasons. First, the tilt-in cleaning feature lets you clean both the interior and exterior glass surfaces from inside the room – useful when the exterior is exposed to salt air, organic debris from surrounding tree canopy, or heavy rain staining. Second, double hung windows allow top-sash ventilation, which lets hot air exit at ceiling level while cooler air enters lower, which is a practical advantage in a climate where cross-ventilation matters nine months of the year. Single hung windows cost slightly less per unit and are a reasonable choice where cleaning access isn’t a concern and ventilation needs are met by other openings, though some homeowners prefer Awning & Hopper Windows for certain applications. We’ll note both options in the written survey so you can compare them on price and specification before committing.

How much do single and double hung window replacements cost in Three Lakes?

Single and double hung window replacement in Three Lakes runs from roughly $420 to $1,100 per window installed, depending on the product tier, glass specification, impact rating, and opening condition. Standard non-impact vinyl replacements come in at the lower end of that range; impact-rated units in larger or custom openings approach the upper end. Rough opening repairs – rot, corroded buck frames, water damage – are priced per opening and stated in the written scope before work begins. Call (786) 808-5792 for an exact price based on your openings. The estimate is free and the written price you receive is the number that appears on your invoice.

Do single and double hung replacement windows in Three Lakes need to be impact-rated?

For most homes in Three Lakes, yes. Miami-Dade County’s wind-borne debris region requirements apply to the area, and Florida Building Code requires that openings in the wind-borne debris region be protected either by impact-rated glazing carrying a Miami-Dade NOA or by an approved shutter system. If your current windows are standard float glass with no shutters, they don’t meet that requirement. When we complete the measured survey on your home, we document the existing glazing specification and confirm the applicable product approval path for each opening. If you’re unsure whether your current windows comply, that’s a question the survey answers in writing.

How long does single and double hung window replacement take for a typical Three Lakes home?

A single-window replacement is typically completed in two to four hours. A full home – eight to fourteen windows, which is common for a Three Lakes single-family home in the 1,400 to 2,200 square foot range – usually takes one to two full days depending on opening conditions and whether any rough opening repairs are needed. The timeline is stated in the written scope before scheduling. We don’t give you a window that spans a week; the installation date and the expected completion date are both on the document. Call (786) 808-5792 to schedule the measured survey and get a timeline specific to your project.
