What It Actually Costs to Replace Windows in a South Florida House
A full-house window replacement in South Florida typically runs $8,000-$25,000 for impact-rated installations, with most 3-bedroom homes falling in the $12,000-$18,000 range once permitting, rough-opening repairs, and code-compliant materials are factored in.

In our market, the gap between online “national average” pricing and real project cost is wider than anywhere else in the country, and it catches homeowners off guard every time.
We grew up in Hialeah watching houses get gutted and rebuilt block by block, and we’ve spent more than two decades since learning why South Florida window jobs go sideways. The climate here isn’t just hot - it’s a salt-air, hurricane-cycle, concrete-block environment that turns standard replacement logic on its head. When Raymond Estevez scopes a whole-house job, he’s checking for what the national cost guides never mention.
Why South Florida Window Costs Break the National Mold
The internet will tell you $300-$700 per window. That’s vinyl, non-impact, in a wood-frame house somewhere in the Midwest. Here’s the South Florida reality:
| Cost Component | Typical Range |
|---|---|
| Impact-rated window (material only) | $400-$1,200 per opening |
| Installation labor per window | $250-$500 |
| Rough opening repair (deteriorated buck, stucco damage) | $150-$400 per window |
| Permit, NOC filing, inspections | $800-$1,500 total |
| Full-house project total | $8,000-$25,000 |
Homes built before 1990 across Miami-Dade, Broward, and Palm Beach counties - think neighborhoods like Lauderhill, North Miami, and older pockets of Hollywood - often have original aluminum single-pane windows set in concrete block with wood bucks that have been cooking in masonry moisture for 40+ years. You don’t know the buck’s condition until the old window comes out. We’ve opened roughings that looked fine from the living room and found powder where solid wood should be. That discovery happens at demolition, not at the quote stage, unless someone specifically assesses for it.
Our process includes a pre-demolition probe at representative openings. It’s not foolproof, but it catches enough that our quotes reflect reality more often than not. “Do it right the first time or you’ll do it twice - and the second time always costs more.” That’s been true on every job site from Coral Gables to Boca Raton.
What the Permitting Timeline Really Looks Like
A full-house window replacement in South Florida triggers a Notice of Commencement filing, a building permit application, and a final inspection that requires either the homeowner or contractor to be present. From permit application to final inspection approval, you’re looking at 4-8 weeks, not the “1-2 day installation” some companies advertise. That 1-2 days refers only to the physical install window - pun intended - after all the paperwork clears.
Here’s what that timeline actually involves:
- Pre-application site survey and impact-product specification (3-5 days)
- Notice of Commencement preparation and notarization (2-3 days)
- Permit submission to Miami-Dade, Broward, or local municipality (1-2 weeks review)
- Material procurement and staging (1-2 weeks, depending on manufacturer)
- Physical installation (1-3 days for typical 12-20 window home)
- Inspection scheduling and final approval (3-10 days, municipality-dependent)
Contractors who skip the NOC or pull permits after the fact are gambling with your certificate of occupancy and your insurance coverage. We don’t play that game. Groundwork handles every phase - one contractor, every phase - so you’re not chasing down a permit runner while your living room is open to the weather.
Where the Real Savings Hide: Insurance, Volume, and Envelope Assessment
Three factors shift the cost conversation from “expensive” to “investment” in South Florida:
Wind mitigation and insurance reduction. A Miami-Dade or Broward wind mitigation report reflecting new impact windows can reduce the windstorm portion of your homeowners insurance premium by 20-45%, which is why many homeowners ask Do Impact Windows Lower Insurance? (South Florida, FL) before committing. On a typical $3,000-$5,000 annual premium, that’s $600-$2,250 back every year. Over a 10-year window lifespan, that offsets a significant chunk of upfront cost. We document every installation for wind mitigation reporting - our inspector knows exactly what the form requires.
Volume pricing on impact products. Brands like PGT and CGI price on volume. A 15-window whole-house project gets quoted differently than a 3-window repair, both in per-unit material cost and mobilization efficiency. Our relationships with impact window manufacturers pass that advantage through. You won’t get those brackets walking into a supply house as a homeowner.
Envelope-condition assessment before quote. When we scope a whole-house replacement, we document stucco cracking, water infiltration at sills, and frame rot before the quote is finalized. The project price reflects actual scope. Too many South Florida homeowners get a low bid based on best-case assumptions, then face change orders when the crew opens the first wall. Built to spec, not to convenience - that’s the standard Raymond Estevez set from day one.
How to Compare Quotes Without Getting Burned
Not every “window company” in South Florida is equipped for full-house replacement in concrete block. Some are retail operations that subcontract installation to crews who’ve never seen a 1970s Hialeah buck rot scenario. Here’s what separates a real quote from a trap:
Ask specifically about rough opening contingencies. If the quote has no line item or allowance for buck repair, the contractor either hasn’t looked or plans to hit you with change orders. A legitimate South Florida quote includes $150-$400 per window in contingency, or a clear statement that openings were probed and found sound.
Verify permit inclusion. The quote should explicitly state who files the NOC, pulls the permit, and schedules inspections. If it says “permit not included” or “homeowner responsible,” add $800-$1,500 and significant hassle to your total.
Confirm product ratings. Impact windows must carry Miami-Dade NOA (Notice of Acceptance) or Florida Product Approval for the specific installation method being used. Ask for the NOA number. Generic “impact rated” claims without documentation have failed homeowners when insurers or inspectors dig deeper.
Check for envelope integration. Window replacement doesn’t happen in a vacuum. Stucco transitions, sill pan flashing, and integration with existing siding or roofing matter. A contractor who only sells windows won’t catch the water intrusion path above your new Pella or Andersen unit. Our Windows & Doors work is backed by full exterior envelope capability - roofing, siding, stucco - because that’s how South Florida houses actually function.
FAQs
Most whole-house window replacements in South Florida cost $8,000-$25,000, with the majority of 3-bedroom homes landing between $12,000 and $18,000 for impact-rated, code-compliant installations including permits and typical rough-opening repairs. Call (844) 665-0162 for a free estimate based on your home’s actual condition.
Replacement is almost always the better investment for pre-1990 aluminum single-pane windows in South Florida, since repair doesn’t address impact compliance, insulation value, or the deteriorated bucks hidden in concrete block openings - and insurance premium reductions from new impact windows offset the cost over time, a key reason Do New Windows Save Energy? (South Florida, FL) matters for long-term savings. We evaluate repairable versus replaceable on every site visit, but honest assessment usually points toward full replacement in our climate.
The physical installation takes 1-3 days for a typical home, but the full project timeline from permit application to final inspection is 4-8 weeks due to Notice of Commencement requirements, municipal review periods, and inspection scheduling. Any contractor promising a “1-2 day project” is referring only to installation, not the complete legal process.
No - Miami-Dade and Broward counties, along with most of coastal Palm Beach County, require impact-rated products or approved shutter systems for all window replacements under current building codes, and non-impact installations won’t pass inspection or qualify for wind mitigation insurance discounts. We specify PGT, CGI, Andersen, Pella, and other NOA-approved impact lines for every project we take on.
