Single & Double Hung Windows in North Miami, FL
Single and double hung windows are the most common window style in North Miami homes, and window installation done correctly means more than swapping glass – it means a frame that seats flush, a sash that moves without binding, and glazing rated for South Florida’s coastal wind loads. At Sightline Windows & Doors North Miami, every hung window job begins with a measured survey the customer keeps, and the written price on that document is the price on the final invoice. No revisions at the truck, no line items added after the glass is cut.
If you’re comparing quotes or just trying to understand what window installation near me in North Miami, FL looks like in this market, call us at (786) 706-0468 – a live person picks up, any hour. Or read on. We put the details here because that’s what the Haven Standard requires.
This page covers hung window replacement specifically. For the broader category of frame types, glass packages, and installation scope in this area, see our Window Installation in North Miami page.
Single vs. Double Hung: What the Difference Actually Means
A single hung window has one movable sash – the bottom panel slides up, the top stays fixed. It’s the simpler mechanism, fewer moving parts, and generally the less expensive option per opening.
A double hung window has two operable sashes. The bottom slides up and the top slides down, which gives you two ventilation points and lets you tilt both sashes inward for cleaning, unlike Awning & Hopper Windows which hinge at the top or bottom. In a two-story North Miami home where the upper windows face a canal or a busy street, that tilt-in cleaning function is practical, not a luxury – reaching those panes from the outside isn’t realistic.
The frame, glazing, and installation process are identical for both styles. What differs is the hardware count and the sash channel complexity. When we do a measured survey on your opening, we’ll note which style your existing frame was built for, because some older openings in North Miami’s Keystone Point and Sans Souci Estates neighborhoods were rough-framed specifically for single hung units, and retrofitting a double hung into that opening without adjusting the rough frame introduces air infiltration points that undermine the whole job.
Before
AfterWhen You Need Single or Double Hung Windows
- The sash sticks or won’t lock flush. In North Miami’s humidity, wood and older vinyl frames swell seasonally. A sash that doesn’t seat against the stop creates a gap – which is an air infiltration point and, during a named storm, a pressure failure risk. If the latch doesn’t engage cleanly, the frame is likely past adjustment.
- You see condensation between the panes. That film between the glass layers means the insulated glass unit (IGU) seal has failed. The argon fill has escaped, the U-factor has risen, and your air conditioner is compensating. In North Miami’s climate, a failed IGU can add $40-$80 per month to cooling costs depending on the window’s solar exposure.
- The frame shows visible corrosion or sill rot. Salt air from Biscayne Bay accelerates aluminum oxidation and wood rot in neighborhoods like North Miami Beach, Arch Creek, and Biscayne Park. Once the sill is compromised, repainting is a temporary fix – water tracks through the wall cavity next.
- Your windows are not impact-rated and you’re in a wind-borne debris region. Miami-Dade County’s wind load requirements apply to most of North Miami. Non-impact single hung units installed before 2002 very likely don’t meet current Florida Building Code (FBC) Chapter 16 requirements. An insurance renewal or a permit pull for a renovation can trigger mandatory compliance.
- The home was built between 1970 and 1995 and windows are original. Single hung aluminum sliders and hung windows from that era have a rated service life that has passed. The weatherstripping is degraded, the weep holes are likely blocked, and the thermal performance is measured in single-digit R-values.
- You’re replacing multiple windows as part of a planned renovation or permit pull. Permitting one opening in Miami-Dade often creates an inspection window that makes it cost-effective to address adjacent openings at the same time – one mobilization, one permit fee, one inspection.
Our Single & Double Hung Windows Process
- Measured Survey – the document you keep. A uniformed, background-checked Sightline technician arrives on schedule and takes sightline-to-sightline measurements of every opening on the scope. Rough opening width, finished opening, frame depth, wall thickness, and existing reveal are all recorded. This survey is yours. The written quote cannot differ from it – that’s Haven Clause 1: Have it in writing.
- Written Scope and Product Selection. Based on the survey, we specify the frame material, glass package (impact-laminated, low-E coated, or both), and sash configuration that fits the opening and meets FBC requirements for your specific address. We carry product lines including PGT and CGI – both Miami-Dade Notice of Acceptance (NOA) holders – and we specify by what the opening requires, not by what’s easiest to source. You see the unit model, the U-factor, the Solar Heat Gain Coefficient (SHGC), and the price before we order anything.
- Permit Application (where required). Hung window replacements in North Miami generally require a Miami-Dade County building permit when the opening size or glass type changes. We handle the permit application and coordinate the required product approvals. You don’t manage that paperwork.
- Frame Removal and Opening Prep. The existing frame comes out. We check the rough opening for level, plumb, and square – a frame installed out of plumb by more than 1/8 inch across a standard 36-inch opening creates binding and premature weatherstrip wear. We address that before the new frame goes in, not after.
- Installation, Flashing, and Seal. The new frame is set, shimmed, anchored to the rough framing at code-required fastener intervals, and flashed at the sill and head. Sealant is applied at the exterior perimeter. The sash is hung, adjusted for smooth travel, and the locks are tested. Nothing is closed up until the sash moves cleanly and the lock engages without force.
- Documented Photo Record and Sign-Off. Before the crew leaves, a photo record is made – frame condition before removal, rough opening, installed frame, flashing detail, and finished interior and exterior. That record is attached to your file. The 365-Day Done Right Promise is written on the job documentation: if it’s not done right, we make it right. That’s Haven Clause 5: No surprises.
Single & Double Hung Windows Pricing in North Miami
Single and double hung window replacement in North Miami typically runs $420 to $1,100 per opening, installed, with permits included in most standard replacement scopes. That range is wide because the variables are real – frame material, glass package, opening size, and whether the rough opening needs correction all move the number.
| Scope | Typical Range (per opening, installed) |
|---|---|
| Single hung, vinyl frame, standard low-E glass, direct replacement | $420 – $620 |
| Double hung, vinyl frame, low-E glass, direct replacement | $520 – $780 |
| Single or double hung, impact-laminated glass, aluminum frame (PGT or CGI) | $680 – $1,100 |
| Opening correction (reframing, shimming beyond standard) | $80 – $220 additional per opening |
| Permit (Miami-Dade County, typical residential) | Included in written scope |
What moves the price up: impact-rated laminated glass adds cost because the interlayer (the PVB film between the glass lites) is a manufactured component with a lead time. Aluminum frames specified to Miami-Dade NOA standards – like those from PGT’s WinGuard line or CGI’s Series 100 – carry a different unit cost than non-impact vinyl. Opening corrections add labor. A third-floor opening adds staging time.
What keeps the price down: direct replacement into an existing rough opening that is square, level, and the right size for a standard unit is the most efficient scenario. If your openings are consistent in size across a multi-window scope, the per-unit cost typically decreases as mobilization is spread across more openings.
Every price you see from Sightline is written before any work starts. The measurement and the quote are the same document – that’s the founding principle here since 2012.

Impact-Rated Hung Windows in North Miami: What the Code Requires
Miami-Dade County sits entirely within a High-Velocity Hurricane Zone (HVHZ) under the Florida Building Code. That designation means any window replacement – including a single hung unit in a standard bedroom opening – must use products that carry a Miami-Dade Notice of Acceptance (NOA) or a Florida Product Approval (FPA) number demonstrating compliance with the design pressure (DP) ratings required for the building’s height and exposure category.
For most single-story North Miami homes in areas like Keystone Point or the blocks east of NE 6th Avenue, DP ratings in the +40/-50 range are the typical threshold. A two-story home in a coastal exposure category may require DP+50/-65 or higher. When we write the scope on your job, the product spec includes the exact NOA number and the DP rating – not a general claim that the window is “impact-rated.”
Impact glass in a hung window is laminated: two lites of glass bonded by a polyvinyl butyral (PVB) interlayer. When the glass breaks under impact, the interlayer holds the fragments. The frame itself must be rated for the pressure load too – the glass performance and the frame performance are both on the NOA document, and both matter during a Miami-Dade inspection.
Some homeowners ask whether hurricane fabric or accordion shutters on a non-impact window are equivalent for code purposes. For permit purposes, the combination of an approved opening protection system with a non-impact window can meet the FBC – but that’s a conversation that belongs in the scope document, not in a general web page, because the answer depends on the specific shutter approval number and the window’s existing frame condition. We note this because the right answer for your address is in the written survey, not in a general claim.
Energy Performance: U-Factor and SHGC in a South Florida Context
North Miami’s climate – ASHRAE Zone 1A, the hottest-humid zone in the continental U.S. – means the energy performance targets for windows are different here than in any other market. The Florida Energy Code sets maximum SHGC (Solar Heat Gain Coefficient) requirements for windows, not minimum R-values, because solar gain is a larger driver of cooling load than conduction in this climate.
For residential windows in Miami-Dade County, the current Florida Energy Code requires a maximum SHGC of 0.25 for windows in conditioned spaces. A low-E coating applied to the interior surface of the outer lite (the #3 surface position in a double-pane unit) is the standard way to meet that threshold. When we specify a unit for your opening, the SHGC and U-factor appear on the written scope. You can confirm those numbers against the NFRC label on the unit when it arrives.
A window with an SHGC of 0.20 versus one at 0.30 is a measurable difference in a west-facing room in North Miami in July. We specify by what the opening requires – solar orientation, adjacent shading from structures or trees, and room use all factor into the recommendation.
FAQs – Single & Double Hung Windows in North Miami
How much does single or double hung window replacement cost in North Miami?
Single hung window replacement in North Miami typically costs $420 to $780 per opening installed, depending on frame material and glass package. Double hung units in the same materials run $520 to $1,100 per opening when impact-rated glass is specified. Those ranges include standard installation labor and permit fees for most direct-replacement scopes – the written quote you receive from Sightline will show each line item before any work starts. Call (786) 706-0468 for a free on-site estimate with a written price you keep.
Do hung window replacements in North Miami require a permit?
Yes, in most cases. Miami-Dade County requires a building permit for window replacements that involve a change in opening size, glass type, or frame material – and because HVHZ compliance requires impact-rated products with NOA documentation, virtually every hung window replacement in North Miami triggers the permit requirement. Sightline handles the permit application as part of the written scope; you don’t manage that process separately.
Is it cheaper to repair a stuck or broken hung window or replace it?
Repair is the right answer when the frame is structurally sound and the problem is isolated – a broken balance spring, a worn weatherstrip, or a failed IGU seal in an otherwise solid frame. Replacement makes more sense when the frame itself has corroded, the unit is not impact-rated, or when the repair cost approaches 40% or more of replacement cost for a unit that still won’t meet current FBC requirements. We’ll tell you which scenario applies to your opening during the measured survey – and that assessment is in writing before any recommendation is made.
How long does hung window installation take?
A standard direct replacement of one to four hung windows in a single-story North Miami home typically takes four to eight hours of installation time once the units arrive. Lead time on the units themselves varies by product line and glass specification: standard vinyl units often ship within two to three weeks, while custom-sized or high-DP impact units from PGT or CGI can carry four to six week lead times depending on current production schedules. We give you the specific lead time for your specified product on the written scope before you approve anything.
