Single-hung or double-hung: which suits a Broward house better?

On price, the single-hung wins: HomeGuide's impact table has it at $400 to $950 installed against $500 to $1,100 for a double-hung. The double-hung lets both sashes move and many tilt in for cleaning, which helps on a second floor. Both need the same HVHZ approval and label before the city signs off.

What should the sticker on a new impact window say?

Florida code lists it: the manufacturer, the model or series, positive and negative design pressure, the largest size tested, the impact rating, the Florida or Miami-Dade approval number and the test standards. That temporary label has to stay on the glass until the building official gives final approval, so don't peel it off early.

Does a Miami-Dade NOA matter if I live in Broward?

Either approval works in Broward. A window can carry a Miami-Dade Notice of Acceptance or a Florida product approval tested to the HVHZ protocols. The Florida Building Commission's product approval Q&A says state approval to those tests is enough to sell in both Miami-Dade and Broward. That Q&A dates from 2005, so confirm it with the permit office.

Can I keep plain glass in a single-hung if the house has shutters?

Yes, as far as the code goes. In the HVHZ, glazing has to pass the impact tests or be covered by an external protection device that does. HomeGuide prices a non-impact single-hung at $300 to $1,500 installed. Shutters only protect the opening when closed, and the wind mitigation form grades the weakest opening on the house.

How big a wind load does a single-hung have to handle here?

It depends on the opening. Broward's design wind speed for houses is a 170 mph three-second gust, and each window's pressure rating comes from testing to TAS 202 in the HVHZ. The label prints that rating as a positive and a negative number. Ask the installer to set each unit's rating next to the pressure its opening requires, in writing.

Timeline: one Broward installer's July 2026 list shows factory waits from 3-4 to 12-14 weeks by brand; Bob Vila estimates about two hours to set each window.
Wind rating: houses in Broward are designed for a 170 mph gust, and each unit's label has to show a Florida or Miami-Dade approval number.
Permit: every window swap in Pompano Beach needs a city permit, whatever it costs.

Pompano Windows lines you up with a Broward installer who measures and sets hung windows: impact single-hungs, double-hungs, and plain-glass units that sit behind shutters. Tell us how many openings there are and which rooms they're in. The installer phones back to arrange a measure, and you can ask for each unit's approval number and design pressure on the written quote.

Single-Hung Window Types for Broward Homes

Hung windows slide up and down in the frame. The choice is how many sashes move and whether the glass itself carries the impact rating.

Impact single-hung windows

Only the bottom sash opens; the top one is fixed. This Old House counts it among the cheapest window styles because the design is simple and installation is fairly easy. The glass is laminated: an interlayer between two panes holds it in place when it cracks.

Installed, impact (HomeGuide): $400 to $950; the unit alone $300 to $550.
Installed, impact (This Old House): $300 to $950.

Double-hung window with both sashes tilted inward for cleaning in a bedroom

Double-hung windows

Both sashes slide, so you can open the top, the bottom or both, and many tilt inward so the outside glass can be cleaned from the room. In a 2025 This Old House survey of 1,000 homeowners, double-hung was the most-bought style, chosen by over 40%. That extra moving sash costs more and adds weatherstripping: This Old House's magazine calls double-hungs hard to weatherstrip.

Installed, impact (HomeGuide): $500 to $1,100; the unit alone $400 to $700.
Installed, non-impact: $350 to $2,500 in HomeGuide's general guide, $300 to $1,000 in Fixr's.

Non-impact single-hung behind shutters

Florida's HVHZ rules give a second route: glazing either passes the impact tests or sits behind an external protection device that does. A plain single-hung costs less up front, $300 to $1,500 installed in HomeGuide's figures and $250 to $700 in Fixr's, but the opening is protected only when the hurricane shutters are closed. The wind mitigation form grades the house by its weakest opening.

HVHZ Impact Window Rules in Broward

Every rule below applies to every impact window and door on the site. Other pages link here rather than repeat it.

The zone
The Florida Building Code defines the High-Velocity Hurricane Zone as Broward and Miami-Dade counties, so all of Pompano Beach is in it.
Design wind speed
Structural calculations in Broward use a 170 mph three-second gust for Risk Category II buildings such as houses, 156 mph for Category I and 180 to 185 mph for Categories III and IV. Miami-Dade's Category II figure is 175 mph.
Large-missile test
Glazing up to 30 feet above grade is tested under TAS 201 and TAS 203: a 9-pound 2x4 timber striking at 50 feet per second. Higher units take the small-missile test (see condo windows).
Pressure test
Windows and sliding doors in the HVHZ must comply with TAS 202 and with ASTM E1300 or Section 2404. Their design pressure rating is set under section 1709.5.
Product approval
State law requires approval for windows, exterior doors, shutters and impact systems. Broward buyers can accept either a Miami-Dade NOA or a state approval that passed the HVHZ tests.
The label
It must show the manufacturer, model or series, positive and negative design pressure, maximum size tested, impact rating, the Florida or Miami-Dade approval number and the test standards. It stays on the window until the building official's final approval.
Impact claims
Marketing a product as hurricane or impact protection without that approval falls under Florida's Deceptive and Unfair Trade Practices Act.

What to Check on a Single-Hung Quote

Size against the label
Each window's width and height should fall within the maximum size tested on its approval.
Pressure against the opening
Ask for each unit's positive and negative design pressure next to what that opening requires.
Bedrooms
A sleeping room's window still has to meet the egress sizes, unless the replacement is the largest standard unit of the same style that fits the old opening.
Payment
If the deposit is more than 10%, ask about the deposit rule and its 30-day permit clock.
