Kendall Impact Windows: The 1980s House Upgrade Nobody Regrets
If your Kendall home still has the original aluminum sliders, impact windows pay back in three ways at once. Here is the honest math on each.
Most Kendall homeowners who finally pull the trigger on impact windows have one thing in common. They wish they had done it five years earlier. We have heard this so many times that we now warn people about it during the estimate, mostly because they will be calling us back to say it themselves anyway.
The reason is not the storm protection. That is the brochure pitch. The real reason is that impact windows pay back in three ways at once, and most homeowners do not notice the payback fully until they live with it for a year.
Payback one: the AC bill
A 1980s Kendall house with original aluminum single-pane windows is leaking conditioned air every minute the AC is running. The seals are gone, the frames have corroded, and the glass itself has zero thermal performance. Modern impact glass with Low-E coating and argon fill stops a meaningful amount of the solar heat that walks into your living room every afternoon.
The number we hear most often from Kendall homeowners after a full impact-window install is around 10 to 20 percent on summer cooling cost. The exact number depends on how leaky the old windows were and how big the south and west-facing glass is, but the savings is real. Not "manufacturer marketing" real. Actual electric bill real.
Payback two: the insurance premium
The wind-mitigation credit for fully opening-protected homes in Miami-Dade is one of the cleanest insurance discounts available. When every window and every door on your house is impact-rated (or impact plus approved shutters), your carrier applies the maximum credit at renewal.
For most Kendall homes the annual premium drop is meaningful enough that the math on the install changes. Over the years, the lower premium covers a noticeable chunk of the project. That does not include the resale value uplift, which is real but harder to put a number on.
Payback three: the things you did not think about
The noise reduction is the one that surprises everyone. Kendall in 2026 is not exactly a quiet neighborhood. The leaf blower three doors down, the bass coming from the truck at the stoplight, the dog that has been barking since 4 a.m. somewhere on your block: laminated impact glass cuts that noise meaningfully. It does not eliminate it. It just turns it down from "intrusive" to "distant".
The UV blocking is the other one nobody mentions. Florida sun fades furniture, floors, photos, and artwork. Modern impact glass blocks the majority of UV that gets through the old single-pane windows. Your dining room rug stops fading. Your sofa stops losing its color near the front window.
The shutters versus glass question
People still ask why not just install shutters. Fair question. Shutters work, in the sense that they protect the opening once deployed. The problem is the "once deployed" part. Storm panels need to be brought up from the garage, lifted, fastened, then taken back down. Accordion shutters are easier but they block daylight when closed and look industrial when open.
Impact glass is permanent protection that works on calm days too. The AC bill, the noise reduction, and the UV blocking happen on every sunny Tuesday in November, not just during hurricane season. The lifetime value tilts strongly toward impact for most Kendall homes.
The PGT, CGI, ES Windows decision
For most Kendall homes we install PGT WinGuard. It is the workhorse: Miami-Dade NOA portfolio, fair pricing, the manufacturer dealer network is solid. CGI Estate is the upgrade for heavier extrusions and a more architectural look. ES Windows is the import option for custom shapes or higher-end projects.
We pick the line based on your house and your budget, not based on what has the best contractor margin. That is a thing in the industry. It is not how we work.
The install week
A typical Kendall full-house impact-window install runs 3 to 7 working days once materials arrive. Materials take 4 to 8 weeks for standard PGT orders, longer for custom shapes. The crew works room by room. We protect floors and furniture, vacuum daily, and walk through every opening at the end.
The Miami-Dade County permit is part of our scope. We pull it at signing, schedule the inspection, and close out. You do not stand in any line.
Where to start if budget is tight
If the full-house install is not in the cards this year, the highest-payback openings to do first are the south and west-facing windows (UV and heat exposure), the largest sliders (biggest single energy leak), and the front door (security and curb appeal). You will not get the full insurance credit until every opening is protected, but you will see the energy and noise improvements right away.
We can also help you phase the project across two seasons. A lot of Kendall homeowners do exactly this.
If your Kendall impact-window project has been on the "someday" list for a while, the someday is usually a better year than you think. We are happy to walk the house and itemize the quote by opening. No pressure, no bundle pricing, no theater.
