Fast, Reliable Window Installation Across Key Biscayne
Window installation in Key Biscayne runs $1,850-$4,200 for a standard impact-rated single or double hung unit, and most jobs complete in one day once the sash arrives on site. A typical whole-home replacement of 10-14 windows in a Key Biscayne condo or single-family house lands between $24,000 and $58,000, depending on brand line, opening size, and millwork conditions. Call (954) 280-4413 for a fixed, written quote before you order anything. You’re on a barrier island with salt in the air from every direction and Miami-Dade’s HVHZ code demanding NOA-certified product in every opening. That’s not a mainland job, and it should not be priced like one.
Why TruePane Windows & Doors Is Key Biscayne’s Preferred Window Installation Company
We’ve pulled enough permits on Crandon Boulevard and along Harbor Drive to know what the inspectors flag before they walk in. Dale Kessler founded TruePane in 2008, but the craft runs back many years through two generations of glaziers, and the rule on the whiteboard has not changed: if the pane is not true, the job is not done. Window Installation on Key Biscayne is not a side trade for us. It’s the job we built the company around.
Key Biscayne homeowners call us because the window that passed inspection in Coral Gables still fails here within seven years. Salt spray off Biscayne Bay hits the west elevation while Atlantic brine works the east, and the hardware corrodes from both sides at once. That is not a theory. It’s why homeowners call us for Key Biscayne Window Replacement every month in aging mid-rise towers along the Crandon corridor and in older single-family homes near the Village. Our technicians are background-checked, uniformed, and trained to measure every opening twice. When we schedule a date, we’re there. When we quote a price, it’s fixed. And when the job is done, both manufacturer warranty layers are registered in writing before the truck leaves your driveway.
That last part matters here more than on the mainland. Key Biscayne’s HOA boards and condo associations ask for documentation. They want to see the NOA number, the warranty registration, the permit. We hand them a file, not an explanation.
Our Window Installation Services in Key Biscayne
Casement Windows
Casement windows are the workhorse of Key Biscayne condo replacement jobs. They seal tight against wind-driven rain, and when the sash is closed, the locking points engage evenly around the frame. In a 1970s Crandon Boulevard tower, we replaced original aluminum single-hung units with Impact Windows & Doors - Key Biscayne casement units using stainless-steel hardware and fusion-welded frames. That was a 40-unit pull on a single Miami-Dade permit, and the association’s price stayed fixed in writing before the first sash was ordered. If your condo board is looking at a building-wide replacement, we coordinate the permitting, the staging, and the paperwork so you do not have to.
Typical casement window installation in Key Biscayne runs $2,100-$4,600 per opening, including the impact glass and NOA-certified frame.

Awning Windows
Awning windows hinge at the top and open outward, which gives Key Biscayne homeowners ventilation even during light rain without letting the Atlantic breeze turn into a puddle on the sill. In the island’s ranch-style homes, awning windows often go in kitchens and bathrooms where high, wide openings are common. One thing worth knowing: on Key Biscayne, the operator hardware gets hit hardest by omnidirectional salt. We spec marine-grade stainless or coated hardware on every awning install here, because the standard stuff pits within a few years. Typical cost: $1,900-$4,100 per window, depending on size and brand.

Fixed & Picture Windows
Fixed and picture windows are the windows with no moving parts, and on Key Biscayne they’re usually the big glass facing the bay or the ocean. That means laminated impact glass, heavy frames, and careful flashing because the wind load on a 6-by-8-foot fixed unit at sea level is serious. We install Energy-Efficient Windows - Key Biscayne fixed units in condo towers and in newer luxury construction near the Cape Florida area, and we always register both warranty layers before we leave. Typical installed cost: $1,750-$4,400 per unit, depending on the size of the lite and the frame material.

Single & Double Hung
Single and double hung windows still show up in Key Biscayne’s older ranch-style homes and in condo units that have never been retrofitted. The double hung lets you open the top sash, which helps move hot air out of a second-story bedroom on an island where the sea breeze is strong but the humidity never quits. On the older frames, the balances and tilt-latch hardware corrodes faster here than anywhere else in Miami-Dade, so we swap in coated or stainless components as part of the install. Budget $1,850-$3,900 per opening, installed.

Trusted Brands We Service in Key Biscayne
We are an authorized installer for more than a dozen manufacturer lines, and on Key Biscayne we see a lot of CGI, ES Windows, and ECO Window Systems product because those manufacturers build specifically for Florida’s HVHZ code environment. When your HOA or architect specifies one of these lines, we quote them side by side on paper so you see exactly what you’re buying. We do not stock parts for every brand in the truck, but we order ahead for Key Biscayne jobs and we sequence the work so you’re not living with a boarded-up opening while the sash clears freight. For Key Biscayne customers, we pull the NOA documentation for the specific product before you commit, so there’s no surprise at the permit counter.
Common Window Installation Problems We See in Key Biscayne Homes
- NOA certification gaps in pre-Andrew buildings. Original aluminum-frame windows in Key Biscayne condos built before 1992 often carry no Miami-Dade Notice of Acceptance. When an inspection flags them, the unit owner is not patching one window – the building is looking at full replacement, and sometimes a bulk HOA contract down the whole floor. We handle the multi-unit coordination and the single permit pull.
- Omnidirectional brine corrosion. Stainless-steel hinges and locking hardware that would last 15 years in Coral Gables pits and seizes in 5 to 7 years here. The reason is simple: Key Biscayne sits entirely at sea level with water on both sides, so salt spray hits windows from every compass direction, not just the ocean-facing elevation. We spec hardware rated for that environment.
- Custom millwork lead times that wreck the schedule. Homeowners who want architectural glass or specialty finishes on premium brand windows discover that long-lead custom sash and jamb components routinely add 8 to 12 weeks. On Key Biscayne, where many homes are high-end and the window openings are non-standard, this is the number one schedule killer. We handle it by locking the price in writing before ordering, then sequencing the work so the lead time does not leave a hole in your wall.
- Condominium HOA requirements. The 1970s-era mid-rise towers along Crandon Boulevard frequently trigger building-wide window replacement mandates, not because a storm broke the glass, but because NOA non-compliance and brine-accelerated frame failure show up on every unit of the same floor at the same time. That converts a one-unit residential job into a HOA-governed, multi-unit bulk contract. We have managed those pulls, including the 40-unit casement replacement described above.

FAQs - Window Installation in Key Biscayne
Key Biscayne condo windows fail on entire floors at once because the brine exposure and the original window age are uniform across the building. A 1970s tower along Crandon Boulevard was built with aluminum-framed single hung units that all hit the end of their service life in the same window of time. Add omnidirectional salt spray from the bay on one side and the Atlantic on the other, and the frame pitting and hardware seizure appear on every unit of the same floor simultaneously, not one unit here and there. That is why so many of these buildings convert to a HOA-governed bulk replacement contract. If your association is at that point, call (954) 280-4413 and we’ll walk through the coordination and the single permit pull.
Yes. Miami-Dade County’s High Velocity Hurricane Zone designation applies to every structure on Key Biscayne, regardless of which direction the window faces. The island is a narrow barrier strip with no mainland buffer, so a window facing Biscayne Bay takes the same wind-driven debris risk as one facing the Atlantic. Every product we install in Key Biscayne carries a Miami-Dade Notice of Acceptance, and we provide the NOA number before you commit so the permit goes through without a stall.
Standard stainless-steel hardware on Key Biscayne pits and seizes within 5 to 7 years because salt spray hits it from every compass direction simultaneously, not just the ocean side. What holds up is marine-grade 316 stainless or a factory-applied corrosion-resistant coating on the hinges, locks, and operator arms. We spec that hardware on every Key Biscayne install, and we do not charge a mainland price for it. Call (954) 280-4413 and we’ll show you the difference on paper.
Yes, and we insist on it. High-end window orders with architectural glass or specialty finishes carry long lead times, and the price has to be locked before the sash goes into production, or you inherit the supplier’s overrun. We fix the price in writing before any material is ordered. That’s the only way to prevent a mid-job change order on a 9-to-12-week custom order. When you call for a quote, the number you get is the number on the bill.
Lead times for the same window are generally the same in Key Biscayne as in mainland Miami, because the delay is in the supply chain, not the geography. Custom sash and jamb components from premium brands add 8 to 12 weeks regardless of where the house sits. What differs on Key Biscayne is the sequencing: because we coordinate with HOA boards and pull permits for multi-unit buildings, the on-site work often has to be scheduled around elevator access, building management hours, and neighbor notification. We handle that scheduling so the lead time does not idle the job. Call (954) 280-4413 for a measured timeline.
