Fast, Reliable Impact Windows Across St. Petersburg

Impact window installation in St. Petersburg typically runs $800 to $1,500 per window for standard openings, with whole-home packages ranging from $8,000 to $25,000 depending on how many openings you have and what shape your framing is in once we open the walls. Most retrofits on older concrete block homes take one to two days of on-site work once your custom units arrive, though fabrication itself runs four to six weeks. If you’re in Old Northeast, Kenwood, or Disston Heights and want a straight answer on what your specific house will cost, call (386) 559-6999 and we’ll schedule the free in-home measure.

Winslow Windows & Doors knows St. Petersburg the way only a company that sends its own crews here does. We understand the salt air coming off Tampa Bay, the jalousie windows still sitting in 1950s CBS bungalows, and the insurance pressure Pinellas County homeowners live with. Ed Winslow’s name is on the door, and on every job we do. That’s not a slogan. It’s how we’ve operated since 2011.

Why Winslow Windows & Doors Is St. Petersburg’s Preferred Impact Windows Company

We’re locally owned and owner-operated, with a published address and license number. No shell companies, no subcontracted crews you’ve never heard of. When a Winslow technician pulls up to your home in Euclid-St. Paul or Greater Pinellas Point, that person is background-checked, uniformed, and knows exactly what your job requires because they’ve done it hundreds of times in this city.

St. Petersburg homeowners call us because a live person answers the phone 24 hours a day, seven days a week. Not a voicemail loop, not a call center in another state. When you call (386) 559-6999 at 2 a.m. because a window just failed after a storm, somebody picks up. That’s been true since our first year in business, and it’s never changed.

Our 36500-Day Done Right Promise backs every installation we do in St. Petersburg. If it’s not done right, we make it right. Period. That’s a century-long standard of accountability no national chain will put in writing, and it’s the reason our St. Petersburg customers keep our number saved in their phones.

We also hold authorizations to install eight premium brands: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters here because St. Petersburg homes near the water demand marine-grade frames and hardware that big-box installers simply don’t stock.

Our Impact Windows Services in St. Petersburg

Impact Window Installation

Full impact window installation is our core trade in St. Petersburg, and for good reason. Homes within a mile of either shoreline get hammered by salt air from both Tampa Bay and the Gulf of Mexico, which means the aluminum frames and multi-point hardware on non-marine-grade units corrode within a few years. We install PGT and CGI impact-rated windows with design pressures matched to your specific opening, never exceeding the +/-100 PSF ceiling, and always with Miami-Dade NOA or Florida Product Approval documentation for your insurer.

Window Replacement

Replacing original single-pane windows in St. Pete’s 1940s and 1950s bungalows is rarely a simple swap. In Kenwood, our crew opened up a 1952 CBS bungalow and found the original jalousie frames had corroded so badly from the double-salt-air exposure that the jambs crumbled on removal. We rebuilt the openings with pressure-treated bucks, installed PGT impact single-hung units, and the homeowner’s insurer re-rated the policy before we finished the trim. That’s what window replacement looks like in this city, and we plan for it from the first inspection.

Door Replacement

Impact-rated door replacement in St. Petersburg matters just as much as windows. Front entry doors, sliding glass doors, and patio doors all count as openings on a wind-mitigation inspection. If your original 1960s door has corroded multi-point hardware or a frame that’s swollen from decades of humidity, your insurer may withhold credits until it’s replaced. We install Therma-Tru and ViewLux impact doors, both of which hold Florida Product Approval for St. Petersburg’s wind zone.

Impact Glass Retrofit

For homeowners in Disston Heights and Pinellas Point whose CBS homes were built between 1950 and 1968, jalousie window replacement is one of the single most common jobs we do in St. Petersburg. Those louvered glass panels are now flagged by insurers on wind-mitigation inspections as a liability, and swapping them for impact single-hung units often triggers a carrier re-rate the same week the inspection report is filed. We handle the full retrofit: removal, framing reinforcement, installation, and trim.

Trusted Brands We Service in St. Petersburg

Our St. Petersburg customers typically choose PGT, CGI, or Therma-Tru for impact openings, and we’re an authorized installer for all three. Because we stock common replacement parts locally and coordinate fabrication directly with the manufacturer, turnaround on warranty work and hardware replacements is faster than what a big-box installer can offer. If you’re replacing an older impact window from a brand we don’t carry, we’ll give you a straight answer on repairability and whether a full replacement makes more sense.

Common Impact Windows Problems We See in St. Petersburg Homes

• Corroded aluminum frames and jambs. Homes within a mile of Tampa Bay or the Gulf get a double dose of salt air, which eats through aluminum frames and hardware years faster than inland homes. Non-marine-grade impact windows simply don’t hold up here, and we see failed multi-point locks and crumbling jambs on a regular basis in waterfront neighborhoods.
• Jalousie windows that insurers now flag. If your home in Disston Heights, Euclid-St. Paul, or Pinellas Point still has original louvered glass windows, your wind-mitigation inspection almost certainly docks you for them. Insurers treat jalousies as a liability, and replacing them with impact-rated single-hung units is one of the fastest ways to unlock premium reductions.
• Undersized or rotted framing around original openings. Many 1940s wood-frame bungalows in Kenwood and Old Northeast can’t support the weight of modern impact glazing without reinforcement. We inspect every opening during the measure, and if we find rotted or undersized framing, it’s priced in the written quote before we ever start.
• Failed weatherstripping and air leakage. The humidity and salt air combination in St. Petersburg breaks down weatherstripping faster than almost anywhere else in Tampa Bay. If you’re feeling drafts or seeing condensation between panes, the seal has likely failed, and impact replacement solves both the energy loss and the storm-protection gap in one job.

What Impact Windows Costs in St. Petersburg

Let’s put real numbers on it, because a vague “it depends” doesn’t help anyone plan a budget:

• Standard impact window: $800 to $1,500 per window installed
• Impact single-hung: $900 to $1,800 per window installed
• Large or custom openings: $2,500 to $5,000 per opening
• Whole-home package (10 to 20 openings): $8,000 to $25,000+

St. Petersburg’s older housing stock means the final number on a retrofit often includes framing reinforcement, especially in 1940s wood-frame bungalows where the original openings were never built to carry modern impact glazing. We inspect every opening during the free in-home measure, and you get a written quote before any work is scheduled. No change orders, no surprises on the invoice. That’s the Winslow way, and it’s why homeowners in Old Northeast and Kenwood keep referring us to their neighbors.

Florida Pays You Back

St. Petersburg homeowners have more incentive to upgrade to impact windows than almost anywhere in the country. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows and doors. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit covers 30% of the product cost on qualifying units, up to $600 per year.

The biggest recurring win is the windstorm-premium credit. After a wind-mitigation inspection, which runs about $75 to $150, the windstorm portion of your premium typically drops by around 25% once impact openings are verified. St. Petersburg sits on a peninsula flanked by Tampa Bay to the east and the Gulf to the west, creating a double-barreled salt-air environment that corrodes aluminum frames, hardware, and weatherstripping faster than virtually any other Tampa Bay market. Pinellas County homeowners already face some of the highest insurance premiums in Florida, so upgrading to impact-rated windows and doors has shifted from a luxury to a financial near-necessity. We can’t guarantee what your specific carrier will do, but we provide all the documentation they ask for: Miami-Dade NOA or Florida Product Approval numbers, design pressure ratings, and installation records.

One honest comparison: impact windows versus hurricane shutters. Shutters only protect you if you’re home to hang them before the storm, and they do nothing for energy efficiency, UV fading, or daily security. Impact windows are permanent protection, always in place, with no panels to store or hardware to maintain. We don’t sell shutters, but we’re happy to explain why impact glass is the better long-term investment for St. Petersburg homes.
