Ed Winslow owns this company and puts his name on every job we install in Clearwater. That changes how we approach your windows. We know the difference between what a 1962 ranch on Drew Street needs versus a 1970s mid-rise unit facing the Gulf. We file the right paperwork the first time, schedule around architectural review instead of pretending it doesn’t exist, and don’t leave rough openings sitting open while a committee argues about frame color. If you’ve been burned by vague estimates or crews that vanish after the deposit clears, you’ll notice the difference immediately.
Why Winslow Windows & Doors Is Clearwater’s Preferred Window Installation Company
We’re the locally owned, owner-operated alternative to the faceless national chains. Ed founded Winslow Windows & Doors in 2011, and since then we’ve built a reputation across Clearwater for showing up when we say we will, answering the phone with a live person 24/7, and standing behind every installation with our 36500-Day Done Right Promise. That’s not marketing language. If it’s not done right, we make it right. Period.
Clearwater homeowners deal with a set of conditions most window companies simply don’t understand. Salt air off the Gulf and the Bay hits your frames from two directions at once. Original aluminum jalousies from the 1950s and 60s corrode in half the time they would ten miles inland. Your insurance company is looking for any reason to non-renew a policy in coastal Pinellas County. We know this because we live it with you. Our Window Installation team has walked through hundreds of Clearwater homes off Gulf-to-Bay Boulevard, Belcher Road, and McMullen Booth, and we’ve seen every failure mode this climate can throw at a window.
Every technician who arrives at your door in Clearwater is background-checked and in uniform. You’ll know who’s coming before the truck pulls up. We publish our address and license number. We don’t hide behind shell companies or 800-number call centers. A real person picks up the phone at 2 a.m., because hurricanes don’t check business hours, and neither do we.
Our Window Installation Services in Clearwater
Clearwater’s housing stock is a mixed bag of 1950s-1980s CBS construction, beachside condos, and a growing number of newer builds east toward Countryside. That means no single window style fits every home here. We carry and install the styles that actually match Clearwater architecture, and we’ll help you choose based on your exposure, your HOA rules if they apply, and what your wind mitigation inspector needs to see.
Single & Double Hung Windows
Single and double hung windows remain the most common replacement choice in Clearwater’s older neighborhoods like Morningside and Greenwood, where ranch homes were built with vertical slider openings. We install PGT WinGuard single-hung units here regularly, using laminated glass interlayers that satisfy Florida Product Approval requirements and give your wind mitigation report something to work with. Double hungs add top-down ventilation, which matters in March and November when Clearwater’s humidity drops and you actually want to open a window.

3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliders are a staple in Clearwater’s condo corridor and larger ranch homes where wide openings look out over water. These openings catch the most salt spray and frequently the most wind, which is why we spec marine-grade hardware and impact-rated frames rather than standard aluminum. On Clearwater Beach and Island Estates, a 3-lite slider replacement that fails architectural review because of frame color or glass tint will cost you four to six weeks of delay. We handle that review process for you.

Casement Windows
Casement windows seal tighter against wind-driven rain than any other operable style, which makes them a smart choice for Clearwater homes facing the Gulf or exposed stretches of the intracoastal. They crank outward from a single side hinge, and when closed, the sash compresses against the frame for a gasket-level seal. In Pinellas County’s 130 mph wind speed zone, that seal is doing real work. Casements also give you a strong visual match for older Florida architecture when a fixed or picture window isn’t practical.

Horizontal Roller Windows
Horizontal roller windows remain common in Clearwater’s 1970s and 80s builds, especially around apartments and smaller CBS homes. The problem is that original versions used single-pane glass in aluminum frames that are now pitted, leaking, and failing wind mitigation review. We replace them with impact-rated vinyl or fiberglass frames carrying Florida Product Approval for Pinellas County, which means the building department sees a compliant submittal on day one instead of a stop-work notice.

Trusted Brands We Service in Clearwater
Winslow Windows & Doors is an authorized installer for PGT and CGI impact windows, and we work regularly with Therma-Tru and ViewLux product lines as well. That authorization matters. It means we install to factory spec, we can file warranty claims without making you chase a middleman, and we know exactly which configurations carry Florida Product Approval for Clearwater’s wind zone. For Clearwater homeowners upgrading from corroded jalousies or single-pane sliders, we frequently recommend PGT WinGuard for its balance of cost, availability, and wind mitigation credit potential. CGI carries a heavier aluminum frame that suits the beachside condo corridor where exterior exposure is relentless. We’ll talk through the honest tradeoffs during your free estimate, not hand you a glossy brochure and vanish.
Common Window Installation Problems We See in Clearwater Homes
- Salt-air corrosion on original aluminum frames. Clearwater’s peninsula geography means frames get hit from the Gulf and the Bay simultaneously. Original aluminum jalousie and slider frames in Greenwood, Morningside, and Druid Hills routinely corrode in 7-10 years, not the 15-20 you’d see inland. The hardware freezes, the tracks strip, and the window stops closing all the way, which is when the air leaks and the insects find their way in.
- Failed wind mitigation inspections on original single-pane glazing. Insurers writing and renewing policies in Pinellas County are increasingly tagging homes with original jalousie or single-pane aluminum windows for non-renewal. These windows pass no wind mitigation inspection category, which means you lose every discount you might otherwise qualify for. Replacing them with impact-rated units is often the single biggest insurance win available to a Clearwater homeowner.
- Architectural review rejections on beachside condo replacements. On Clearwater Beach and the surrounding mid-rise corridor, rushed window wall replacements get kicked back by HOAs because the frame color or glass tint doesn’t match the master spec. That’s a four-to-six-week delay you could have avoided with a proper submittal packet on day one. We prepare those packets, including product approval numbers, sample color strips, and spec sheets, before the committee ever sees the file.
- Sequencing mistakes between review and installation. Ordering custom impact units before the architectural committee signs off on the template change-out leaves you with open rough openings and no glazing for weeks. It happens constantly in Clearwater. We schedule the review first, get written sign-off, then release the fabrication order. Your house never sits exposed, and your project doesn’t stall half-finished.
Pricing for Window Installation in Clearwater, FL
Most Clearwater homeowners spend between $800 and $1,500 per window installed for impact-rated units in standard openings. Single-hung models run $900-$1,800 depending on size and glass package. Large or custom openings, like a wide 3-lite slider facing the water, range from $2,500 to $5,000 installed. Whole-home packages typically land between $8,000 and $25,000, driven by opening count, floor height, frame material, and how much structural remediation the rough openings need after decades of salt exposure.
Clearwater’s market pricing reflects a few local factors. The coastal wind zone means every opening needs products with the right design pressure rating and Florida Product Approval, not off-the-shelf boxes from a big-box aisle. Second-floor and higher work on beachside condos costs more because of access and structural fastening requirements. And architectural review, where applicable, adds time but not line-item inflation if it’s managed correctly. Call (386) 559-6999 to schedule your free in-home measure and a written quote. The number on the quote is the number you pay. No change orders, no discovery-day surprises.
What Window Installation Costs in Clearwater
Clearwater’s pricing anchors look like this: impact windows generally run $800-$1,500 per window installed for standard openings; impact single-hung units sit at $900-$1,800; large custom openings like bay or garden windows run $2,500-$5,000; and complete whole-home packages land between $8,000 and $25,000 or more for larger beachside properties with many openings. What moves the price most in Clearwater is opening count, wind zone requirements on your specific lot, whether the work is ground-floor or elevated, and which frame material makes sense for your exposure. Vinyl and fiberglass both hold up well to two-sided salt air, but they carry different price points and different availability timelines.
Every estimate includes a free in-home measure and a written, line-item quote. You’ll see exactly what each opening costs, what the install labor runs, and what you’re paying for in terms of product approval documentation and wind mitigation paperwork. We don’t bury costs in vague “labor included” bundles or spring a change order on you after the contract is signed. What we quote is what gets installed.
Florida Pays You Back
The incentives stack if you qualify, and they’re worth planning around. My Safe Florida Home matching grants can cover up to $10,000 in qualifying wind mitigation upgrades for eligible homeowners. Florida also exempts impact-resistant windows and doors from sales tax, which on a $15,000 whole-home job is a meaningful chunk of change. The federal 25C energy credit returns 30% of the product cost, capped at $600 per year, for qualifying efficient units. And after a wind mitigation inspection (typically $75-$150), many Clearwater homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers, so we never guarantee a specific dollar figure on your premium reduction. We do make sure your installation is positioned to qualify.
One comparison worth making up front: impact windows versus hurricane shutters. Shutters are cheaper at the point of sale, but they only work when someone is home to put them up, and they do nothing for day-to-day air sealing, UV protection, or corrosion resistance. Impact windows are permanent. Nothing to hang, nothing to store, nothing to forget in August. They’re working every single day, whether a storm is in the Gulf or not. For a Clearwater homeowner, that’s the difference between a seasonal ritual and a permanent upgrade. Winslow Windows & Doors installs impact windows and doors. We do not sell or install shutters, and we’ll tell you plainly if a shutter-based approach makes more sense for your specific property budget.

FAQs - Window Installation in Clearwater
For window replacement in Clearwater, you need a Florida Product Approval (FL number) that covers Pinellas County’s wind requirements. Miami-Dade NOA applies to Miami-Dade and Broward counties and does not automatically transfer to Pinellas County. The building department in Clearwater checks for Florida Product Approval numbers tied to the specific configuration of your installation. Our submittal packets include the correct product approval documentation for Pinellas County’s 130 mph wind speed zone, so review isn’t stopped at the counter. Call (386) 559-6999 and we’ll walk you through what your specific opening needs.
Architectural review in a Clearwater Beach condo typically adds 2-6 weeks to the timeline, depending on the specific HOA’s meeting schedule and whether the submitted frame color, glass tint, and product spec match the master requirements. Rushed submittals that don’t match the spec get kicked back, which resets the clock. We prepare the full packet, including product approval numbers, color samples, and spec sheets, before the committee ever sees it. That front-loaded work typically keeps the review to a single cycle. Call (386) 559-6999 for a realistic timeline on your specific building.
Yes, replacing original jalousie windows with impact-rated glass is one of the largest single insurance moves a Clearwater homeowner can make. Jalousie windows pass no wind mitigation inspection category, and insurers writing policies in coastal Pinellas County are increasingly tagging homes with original jalousies for non-renewal. After replacement, a wind mitigation inspection can unlock premium reductions that often run $1,000-$3,000 or more per year depending on your carrier and coverage. We recently replaced original aluminum jalousies on a 1962 CBS ranch off Drew Street in Morningside with PGT WinGuard single-hung units, filed the wind mitigation paperwork, and the homeowner’s next renewal came back with a $1,400 annual premium reduction. That’s real money every single year. Call (386) 559-6999 to get your home assessed.
For Clearwater’s two-sided salt air, impact-rated vinyl and fiberglass frames with marine-grade hardware hold up far better than the original aluminum frames that corrode in 7-10 years along the peninsula. Aluminum oxide coatings break down under that double salt load from the Gulf and the Bay. Vinyl resists the chemical corrosion entirely, while fiberglass adds structural rigidity for larger openings and higher wind exposures. We’ll match the frame material to your specific lot conditions, not hand you a one-size-fits-all answer. Call (386) 559-6999 to talk through your options.
In most 1950s CBS homes in Clearwater, you can keep the existing rough openings and install impact-rated replacement windows sized to fit. The concrete block structure is sound; what needs replacing is the glazing and frames. However, in Clearwater’s wall construction, the existing opening depth is sometimes shallower than modern impact frame requirements. We measure and spec the replacement to fit without cutting new openings, and if any opening needs minor adjustment, we’ll price that into the written quote before any work starts. Call (386) 559-6999 to schedule a free measure and find out what’s feasible for your specific home.
Clearwater’s Salt Air and Your Windows
Here’s something every Clearwater homeowner should know, and it doesn’t appear on any generic window website. Clearwater sits on a narrow peninsula with the Gulf of Mexico to the west and Clearwater Harbor and Old Tampa Bay to the east. That means the salt-laden air arrives from multiple compass directions year-round. Original aluminum jalousie and single-pane slider windows in neighborhoods like Druid Hills, Greenwood, and Morningside corrode in 7-10 years, not the 15-20 years typical of interior Pinellas County. The aluminum oxide coatings break down, the hardware freezes, and the insulated glass unit edge seals fail prematurely. Impact-rated vinyl or fiberglass frames with marine-grade hardware aren’t an upgrade choice here. They’re a practical necessity. Nothing about this dynamic changes if you buy from a national chain, and a generic aluminum frame product without Florida Product Approval for Pinellas County won’t even clear the building department’s first review pass.
The Clearwater Architectural Review Reality
If you live in Clearwater Beach, Island Estates, or any of the mid-rise and high-rise condo buildings along the beachside corridor, window replacement isn’t just a building department matter. It’s an architectural review matter. HOAs in these buildings govern frame color, glass tint, sightline thickness, and sometimes even brand compatibility. A rushed window wall replacement on a 1970s high-rise gets kicked back because the submitted frame color doesn’t match the master spec, and you lose 4-6 weeks before the committee meets again. Your unit sits with old windows while the calendar moves.
We handle that review process for you. Before any fabrication order is placed, we submit a complete packet to the committee: product approval numbers, color strip samples, spec sheets, and installation details. We then wait for written sign-off before releasing the fabrication order, which runs 4-6 weeks for custom units. Your rough openings never sit exposed, and your project doesn’t stall half-finished waiting on a committee. This is how a Clearwater condo window replacement is actually managed, and it’s exactly the kind of local knowledge that separates a company that knows this market from one that’s just filling a truck with labor for the day.
Ed’s name is on the door, and on every job we do in Clearwater. That’s not a slogan. It’s how we operate. Call (386) 559-6999 to schedule your free estimate and see what local accountability actually looks like.
