Why TruePane Windows & Doors Is Seminole’s Preferred Impact Windows & Doors Company
TruePane wasn’t built as a franchise playbook. Dale Kessler founded the company in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. That standard matters in Seminole, where the housing stock demands more than a stock-size window dropped into an old rough opening. Many homes here were built between 1960 and 1980, and the original openings rarely match modern manufacturing tolerances. A company that doesn’t measure twice and order Custom Windows & Doors - Seminole will leave you with gaps, shims, and a seal that fails in the first summer storm.
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen in Seminole, PGT, and CGI. That means we quote side by side on paper, register both warranty layers in writing before we leave your driveway, and never push a line we wouldn’t put in our own mothers’ homes. Background-checked, uniformed technicians do the work. A live person answers the phone 24 hours a day, 7 days a week. We sponsor county fairs and church roof funds because we plan to be in Seminole thirty years from now, still answering the phone when you call.
Our Done Right Promise covers every job: if it’s not done right, we make it right. No paperwork fights. No fine print that covers nothing. That’s The Keystone Standard, and it’s in writing every time.
Our Impact Windows & Doors Services in Seminole
Hurricane Impact Windows
Seminole’s CBS homes were often built with aluminum jalousie windows, the louvered glass units that crank open in strips. Those windows have zero hurricane resistance, and insurance carriers in Pinellas County now flag them as uninsurable openings. We replace jalousies with fully impact-rated casements, single-hung, or horizontal rollers sized to the original rough opening and glazed for Florida’s solar heat gain requirements.

Impact Sliding Glass Doors
The full-width sliders installed in 1970s Seminole homes are single-pane, non-compliant, and no longer legal to retrofit under post-2002 Florida Building Code. We replace them with Seminole Sliding & Patio Doors that are impact-rated and meet the 130+ mph design pressure common across Pinellas County. Frames get fusion-welded corners, stainless steel rollers, and interlocking meeting rails that hold under wind load.

Impact Entry & French Doors
Front entries, French doors, and Seminole Glass Railing Systems face salt-air exposure year-round in Seminole. We install impact-rated entry systems from CGI, CWS, and ES Windows, with thresholds and weatherstripping specified for coastal corrosion cycles. Every door gets measured twice, quoted with the exact hardware in writing, and installed so the reveal is even on all sides. If the door binds in July, that’s a warranty call we answer.

Impact Garage Doors
Garage doors are the largest opening in most Seminole homes, and a non-impact door is the first thing wind-pressure testing flags. We install and brace impact-rated garage door systems, coordinate with your wind mitigation inspection, and make sure the track reinforcement meets Pinellas County’s current code, not the code from when your house was built.

Trusted Brands We Service in Seminole
We’re factory-authorized for CGI, CWS, ES Windows, and ECO Window Systems, which gives Seminole homeowners real choices without a sales pitch attached. If you have existing impact units from one of these lines, we stock weatherstripping, balancers, rollers, and common hardware for local callbacks. Brand-specific replacement glass and frame components are ordered direct from the manufacturer, not through a third-party parts broker, so the lead time and the warranty chain stay clean. You’ll see the exact line item for every manufacturer part on the written quote, before you agree to anything.
Common Impact Windows & Doors Problems We See in Seminole Homes
- Salt-air corrosion on aluminum frames. Homes two to three miles east of Madeira Beach and Treasure Island sit in a constant salt-laden air stream. Aluminum jalousie frames, balancers, and hardware oxidize within 20 to 30 years, leaving sashes that won’t close tight. Once the seal is compromised, moisture gets in and the frame begins to pit. We see this weekly on original 1960s units along 86th Avenue and the streets west of Park Boulevard.
- Insurance non-renewal due to jalousie windows. Pinellas County carriers have started flagging louvered jalousies as uninsurable openings. Homeowners get a letter with a hard deadline to replace them. We handle these insurance-driven jobs end to end, including the wind-load documentation and the post-installation inspection coordination.
- Non-compliant 1970s sliders. Original full-width single-pane sliding glass doors fail current wind-load tests and cannot be legally retrofitted. Removal and replacement with an impact-rated unit is the only code-compliant path. Seminole’s CBS construction makes rough opening reframing rare, but custom sizing is almost always necessary.
- Wrong glass packages on custom orders. Homes in Seminole’s non-standard rough openings frequently require custom-ordered impact units. If the designer doesn’t specify the right U-factor and solar heat gain coefficient for Pinellas County before the order is locked, the windows arrive with the wrong glass package and the project stalls. We specify performance values on every quote, in writing, before the manufacturer order is placed. Impact Windows & Doors in Seminole jobs should not hinge on a guess.
Pricing for Impact Windows & Doors in Seminole, FL
Standard-size impact windows in Seminole run $800-$1,400 per opening installed, including the window, fasteners, flashing, and disposal. Custom-sizes for 1960s CBS rough openings add 15-30%, which is why most Seminole quotes land between $1,100 and $1,800 per window. Impact sliding glass doors run $2,800-$6,500 installed depending on width and brand. Whole-home replacements on a typical three-bedroom Seminole concrete block house run $18,000-$38,000, with the big cost drivers being the number of jalousie replacements, slider width, and whether you’re upgrading from a standard impact package to low-E argon.

The price we quote is the price you pay, fixed before the order is placed.

FAQs - Impact Windows & Doors in Seminole
Pinellas County carriers have flagged original jalousie and single-pane slider openings as uninsurable wind-borne debris risks, especially on 1960s-1970s CBS homes in Seminole, so carriers require impact-rated replacement units or full shutter credits before renewal. We handle insurance-driven replacements end to end, including the wind-load documentation and the post-installation inspection sign-off. Call (954) 280-4413 to talk through what your carrier is asking for, and we’ll quote the compliance work in writing.
Salt-laden air from Madeira Beach and Treasure Island sits over Seminole year-round and accelerates oxidation on aluminum frames, hardware, and weatherstripping, so Seminole homeowners should specify corrosion-resistant finishes, stainless steel rollers, and butyl flashing details on every impact unit. We specify these as standard on coastal Pinellas installs, not as upgrades. Call (954) 280-4413 for a written quote.
No. Jalousie frames cannot be retrofitted to meet Pinellas County’s 130+ mph wind-load requirements, so any repair short of full replacement leaves you non-compliant and uninsurable. We replace entire jalousie units with impact-rated casements or horizontal rollers sized to the existing rough opening. Call (954) 280-4413 and we’ll walk you through the options and a fixed quote.
Custom impact windows for Seminole’s non-standard 1960s CBS rough openings typically run 4 to 10 weeks from order to install, depending on the manufacturer line and glass package. We lock the price in writing before the order is placed, so the lead time doesn’t become a surprise cost on the back end. Call (954) 280-4413 for a timeline based on your exact openings.
Yes. New impact-rated windows and doors are one of the strongest wind mitigation credits available in Pinellas County, and we provide the documentation your inspector and your insurance carrier need after every install. We coordinate the inspection walkthrough so the credits get filed correctly the first time. Call (954) 280-4413 to schedule a free estimate, and we’ll review your current wind mitigation report line by line.
Call TruePane for Impact Windows & Doors in Seminole

That’s the standard we bring to every Seminole job, from the smallest window to a whole-home package.
Call (954) 280-4413 to schedule a free estimate. A live person answers, 24/7. You’ll get a written, line-item quote with both warranty layers registered in writing before we leave the driveway. If the pane is not true, the job is not done.
