Single Hung Impact Windows

Quick answer

Are you replacing older hung windows with hurricane impact glass? Single hung impact windows open from the bottom sash and use laminated glass rated for South Florida wind zones. Typical installed cost runs about $800–$1,800 per opening, with coastal HVHZ and oversized units higher.

Pain point we hear constantly

Homeowners often receive wildly different quotes for the same single hung openings — sometimes tens of thousands apart on a full-home job.

We publish planning ranges, lock the measured scope in writing, and include permit handling with no markup on city fees.

When single hung impact windows make sense

Single hung windows are a familiar choice for bedrooms, living rooms, and many older South Florida homes that already have hung openings. You operate the bottom sash while the top stays fixed, which keeps the look simple and the hardware easy for most households. If your home already has hung windows, a same-style impact replacement often avoids major structural changes.

Miami-Dade and wind-zone notes

In Miami-Dade’s High Velocity Hurricane Zone, products should carry a current Notice of Acceptance that matches the size, glass, and installation details being used. We help you select single hung systems appropriate for your design pressure needs — not just a brochure name. Always verify the NOA against the exact configuration before you order.

What affects single hung pricing

Price moves with opening size, glass package, finish, grid options, and whether the opening needs extra waterproofing or frame work. Coastal and oversized units land higher than a typical mid-size bedroom window. A free on-site measure gives you a locked written quote instead of a phone guess.

Install and permit timeline

Manufacture commonly takes about 4–8 weeks depending on series and finishes. Most residential single hung replacements install the same day once product arrives. We pull the permit, schedule inspection, and work toward close-out so paperwork does not stall after the glass goes in.

How we work differently

  • One accountable company — no warranty blame-shifting between builder, manufacturer, and installer.
  • Written locked price — no surprise fees after you sign.
  • Permits closed — we pull permits, schedule inspection, and close them out for insurance and resale.
  • Published cost ranges — so you can spot outlier quotes before you waste a Saturday.
