Key Takeaways
- Impact windows in St. Petersburg typically run $800-$1,500 per window installed; large or custom openings run $2,500-$5,000.
- Jalousie windows earn zero wind mitigation credits with Pinellas County insurers, so replacement is the only path to premium relief.

- Our Done Right Promise means if the pane is not true, the job is not done, and we make it right with no paperwork fight.
Why TruePane Windows & Doors Is St. Petersburg’s Preferred Window Installation Company
We’ve worked on enough Kenwood bungalows and Old Northeast craftsmans to know what St. Petersburg homes actually need, which is rarely what a national chain rep pushes over the phone. TruePane was founded by second-generation glazier Dale Kessler on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. That standard shows up in the way we measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves the driveway. Our St. Petersburg customers deal with background-checked, uniformed technicians who respect the house and the homeowner, not a rotating cast of subcontractors.
What sets us apart in St. Petersburg is that we are an authorized installer for more than a dozen manufacturer lines including, PGT, and CGI, so we are not pushing one brand to clear inventory. We pull the permit, coordinate the inspection, and make sure your wind mitigation form reflects what actually went into the openings. Most jobs are completed in a single visit once your units arrive. And every job carries our Done Right Promise, because Dale’s rule governs every install we put our name on.
Our Window Installation Services in St. Petersburg
Every St. Petersburg window we install is set to the Florida Building Code wind-load requirements for the opening’s exposure, not just the easiest product to order. Here are the four window styles we install most often in this city.
Single & Double Hung Windows
Single and double hung windows remain the most common replacement in St. Petersburg’s older neighborhoods, where original wood sashes have swollen, rotted, or been painted shut over decades. We install impact-rated single and double hung units that operate cleanly, meet design pressure requirements, and look right on a 1920s craftsman or a 1950s concrete block rancher. In St. Petersburg, we regularly see homeowners replace failed aluminum single-hungs from the 1970s with laminated glass impact units that finally earn wind mitigation credits.

Horizontal Roller Windows
Horizontal roller windows are common in mid-century St. Petersburg homes, especially on elevations where a crank-out casement would block a walkway or a garden bed. The problem with older horizontal rollers here is salt-laden air eating the sill tracks and seizing the rollers. We set new horizontal rollers with corrosion-resistant hardware and proper flashing, and we document the Florida Product Approval numbers so your wind mitigation inspection credits the opening.

3-Panel Sliding (3-Lite Roller) Windows
Three-panel sliding windows open up a Florida room or a back elevation with wide sightlines and real airflow, which matters in a city that holds Guinness records for consecutive sunny days. On St. Petersburg homes near the water, we recommend impact-rated laminated glass 3-lite units with design pressure ratings matched to the exposure, because cheap vinyl sliders with DP 35 ratings or less crack at the jamb under hurricane gusts. The difference is documented compliance versus a second full replacement after the next storm.

Casement Windows
Casement windows give St. Petersburg homeowners the best seal against wind-driven rain, because the sash compresses against the frame when closed instead of relying on a sliding track. That makes them a strong choice for east-facing elevations that catch afternoon squalls off Tampa Bay. We install casement windows with multi-point locking hardware and impact glass where the opening requires it, and we never shortcut the flashing, because a casement that leaks is a wall repair you should not have to make.
We also install awning and hopper windows, picture and fixed windows, bay and bow windows, and garden windows across St. Petersburg. If you are not sure which style makes sense for an opening, we’ll talk it through on site and show you manufacturer lines side by side on paper.

Trusted Brands We Service in St. Petersburg
TruePane is an authorized installer for more than a dozen manufacturer lines, so we are never limited to one brand’s quirks. In St. Petersburg, we install and service windows from PGT, CGI, Andersen, Marvin, Milgard, and Jeld-Wen, plus glass products from ECO Window Systems, Mr-Glass, and ViewLux where the opening calls for them. Because we stock common parts locally and work directly with manufacturer reps, a St. Petersburg homeowner with a failed balance or a fogged sealed unit in an existing Window Installation is not waiting on a distant distribution center. We quote manufacturer lines side by side on paper so you see exactly what you are buying and what it costs.
Common Window Installation Problems We See in St. Petersburg Homes
- Salt-corroded aluminum frames. St. Petersburg’s peninsula position puts homes within reach of salt-laden air from Tampa Bay, Boca Ciega Bay, and the Gulf. Aluminum window frames, sill tracks, and hardware corrode noticeably faster here than even a few miles inland in Hillsborough County.
- Jalousie windows with zero wind mitigation credits. The louvered glass jalousie design is still common in Kenwood, Old Northeast, and Historic Uptown. Because jalousie windows are excluded from wind mitigation inspection credits under Florida’s form, no amount of adjustment or repair moves your insurance premium; only full replacement does.
- UV-degraded seals and weatherstripping. St. Petersburg’s extreme sunshine intensity breaks down vinyl window seals, glazing tape, and weatherstripping faster than most homeowners expect. A cheap vinyl replacement may look fine for five years and then fail at the seal line.
- Low design pressure ratings on cheap replacements. We see homes where a previous contractor installed DP 35 or lower rated vinyl frames. Those units cannot pass St. Petersburg’s required wind-load inspection, and the homeowner pays for a second full replacement. We match design pressure to the opening’s exposure the first time.
Pricing for Window Installation in St. Petersburg, FL
A standard impact-rated window installation in St. Petersburg runs from $800 to $1,500 per window for typical openings. Impact single-hung windows range $900 to $1,800 depending on size, frame material, and design pressure rating. Large or custom openings like a picture window or a 3-panel slider run $2,500 to $5,000 installed. Whole-home packages for a typical St. Petersburg bungalow generally run $8,000 to $25,000 or more depending on opening count and wind zone. What moves the price is opening count, floor height, frame material, and the design pressure your exposure requires. We give you a written line-item quote after measuring every opening twice, and we do not add surprise line items at the end. Call (888) 635-0804 to schedule a free in-home measure and quote.
What Window Installation Costs in St. Petersburg
Here is what we quote most often in St. Petersburg: impact windows run $800 to $1,500 per window installed, impact single-hung runs $900 to $1,800, large or custom openings run $2,500 to $5,000, and whole-home packages run $8,000 to $25,000 or more. The variables are concrete, not mystery: how many openings you have, whether the home sits in a wind zone near the water or further inland, whether it is a single story or elevated, and whether you choose vinyl, aluminum, or custom wood-clad framing. A free in-home measure and written quote is the only honest way to price your specific house, and we are glad to do it. Call (888) 635-0804 to set that up.
Florida Pays You Back
St. Petersburg homeowners can stack a few incentive programs to offset replacement window costs. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades for eligible homeowners. 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 energy-efficient units, up to $600 per year. Once your wind mitigation inspection is complete after installation, windstorm-premium credits average around 25% on the windstorm portion, with the inspection itself running $75 to $150. Programs and carriers set the final numbers, so we will not promise a dollar figure we cannot stand behind, but we will document everything your insurer needs.
One comparison worth making in St. Petersburg: impact windows versus hurricane shutters. Shutters only protect when someone is home to deploy them and they do nothing for insurance documentation until they are installed and rated. Impact windows are permanent protection, no panels to hang in a storm warning, and they are the change your insurer actually credits on a wind mitigation inspection. If you are comparing a big-box retail install quote against a licensed impact specialist, ask the retail rep for the Florida Product Approval numbers on the units they are quoting and whether they are pulling the permit. If the answer is vague, you have your answer.

FAQs - Window Installation in St. Petersburg
No. Jalousie windows are explicitly excluded from wind mitigation inspection credits under Florida’s inspection form, which means no amount of maintenance, sealing, or partial replacement moves your Pinellas County premium. The only path to insurance relief is full replacement of those openings with impact-rated units that carry Florida Product Approval numbers. Call (888) 635-0804 and we’ll assess every opening and give you a written line-item quote.
The required design pressure rating depends on the home’s wind zone, the opening’s height, and its exposure, but St. Petersburg homes near Tampa Bay or Boca Ciega Bay generally require higher DP ratings than inland Pinellas homes. Cheap vinyl frames rated DP 35 or lower routinely crack at the jamb under hurricane gusts and fail the required wind-load inspection. We match design pressure to the opening during our measure and never quote a unit that does not meet the Florida Building Code for that opening. Call (888) 635-0804 for a free in-home measure.
Yes, window replacement in Kenwood, Old Northeast, and every other St. Petersburg neighborhood requires a permit and a wind-load inspection. TruePane pulls the permit, coordinates the inspection, and makes sure the wind mitigation form reflects the units we actually installed. We hand you the documentation before we leave the job. Call (888) 635-0804 to schedule your free estimate.
Salt-laden air from Tampa Bay, Boca Ciega Bay, and the Gulf reaches St. Petersburg homes from multiple directions, and it settles on aluminum frames, sill tracks, and hardware. That causes corrosion years faster than even a few miles inland, and it is why we see seized tracks and pitted frames on homes that are not particularly old. Choosing corrosion-resistant frames and hardware is a practical necessity here, not an upgrade. Call (888) 635-0804 and we will show you what holds up on a St. Petersburg peninsula.
You give your insurer the wind mitigation inspection report, the permit, and the Florida Product Approval numbers for the units we installed. TruePane registers both manufacturer warranty layers in writing before the truck leaves the driveway and provides the documentation package your carrier needs to credit the windstorm portion of your premium. Without that paperwork, even a surviving window does not earn the reduction. Call (888) 635-0804 for a free estimate and a documentation checklist specific to your home.
