Fast, Reliable Impact Windows & Doors Across Dunedin
Impact window and door replacement in Dunedin is rarely a simple swap. It’s an inspection of what seventy years of salt air has done to the frames, the rough openings, and the waterproofing behind the stucco. That’s the work we do. TruePane Windows & Doors has been installing, replacing, and servicing Impact Windows & Doors in coastal Pinellas County long enough to know what a Dunedin home reveals when the old aluminum comes out. If you’re weighing impact windows for a 1950s CBS ranch off Edgewater Drive or a bungalow near the Pinellas Trail, call (813) 320-9346 for a free estimate. We’ll put a real price in writing, not a guess.
Why TruePane Windows & Doors Is Dunedin’s Preferred Impact Windows & Doors Company
Our crew has spent enough mornings on Dunedin jobsites to know the difference between a straightforward sash replacement and a wall that needs a permit-mandated framing repair before the new jamb goes in. That knowledge comes from doing the work, not from a franchise playbook. We’re a second-generation glazier’s operation, founded by Dale Kessler in 2008, and the founding rule on the whiteboard still holds: if the pane is not true, the job is not done.
Dunedin homeowners call us because a live person answers the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form. When you call with a fogged panel or a door that binds in July, you talk to someone who can schedule the truck. Our technicians are background-checked, uniformed, and trained to measure every opening twice. Every quote puts manufacturer lines side by side on paper so you see exactly what you’re buying. And every job is covered by the 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing before the truck leaves your driveway. No paperwork fights. No arguing.
Our Impact Windows & Doors Services in Dunedin
Hurricane Impact Windows
Dunedin sits directly on St. Joseph Sound with the Gulf of Mexico one barrier island away. That places virtually the entire city inside Florida’s Wind-Borne Debris Region, which means any window replacement must meet impact-rated or approved-opening standards under the Florida Building Code. We install impact-rated casement, single-hung, and picture units with fusion-welded frames and low-E argon-filled insulated glass. For a 1950s CBS home, the job often starts with an assessment of whether the original rough opening is sound enough to carry the new load. We check before we quote.

Impact Sliding Glass Doors
Sliding doors on west- and northwest-facing elevations in Dunedin take the worst of the salt air. We regularly replace aluminum sliders whose tracks and threshold pans have corroded to the point where the door drags or the lock no longer engages. Our impact-rated sliders meet Miami-Dade and Florida Building Code wind-load requirements, and we rebuild the threshold with proper flashing so wind-driven rain can’t wick into the rough opening.

Impact Entry & French Doors
A Dunedin front door does more than open and close. It’s the first line against wind-borne debris and the first place an insurance wind-mitigation inspector looks. We install impact-rated entry doors and French door units with reinforced jambs and multi-point locks. If your current door was hung in a rotted wood buck, we’ll find it during the quote and write the repair into the allowance, not spring it on you mid-job.

Impact Garage Doors
Garage doors on older Dunedin homes are a frequent wind-mitigation failure point. A non-rated overhead door can blow in under storm pressure and let the roof lift. We service and replace impact-rated garage doors, including bracing and track reinforcement that satisfies the wind-load requirements for homes this close to open water.

Common Impact Windows & Doors Problems We See in Dunedin Homes
- Corroded aluminum jalousie frames on west-facing elevations. Decades of salt-laden air off St. Joseph Sound seize the louvers closed. When we open walls near Edgewater Drive, we often can’t operate the jalousies without breaking glass, and the frames crumble at the touch.
- Rotted wood bucks behind the stucco. Original single-pane frames in 1940s-1960s CBS homes hide undersized or rotted wood bucks. Once the new impact-rated jamb is fastened and the wall sees uplift load, a bad buck fails the inspection and forces a framing repair.
- Failed waterproofing around sill pans. Decades-old jalousie sill pans let wind-driven rain wick into the rough opening. That rots the sub-sill and triggers a permit-mandated framing repair before our flashing tape can go down.
- Insurance wind-mitigation flags. Original jalousie windows repaired with silicone caulk for decades are a red flag in Citizens Property Insurance inspections. A knowledgeable contractor can spot the compliance issue before the quote is even written.

Pricing for Impact Windows & Doors in Dunedin, FL
Impact window replacement in Dunedin typically runs $950-$2,400 per opening, depending on size, frame material, and glass package. A standard impact-rated casement unit for a 1950s CBS home usually lands around $1,200-$1,800 installed, while a brace-and-track impact garage door replacement can run $2,800-$5,500. Impact entry doors range $3,000-$6,500 with the reinforced jamb and multi-point lock included. The biggest cost drivers in Dunedin are the condition of the existing rough opening and whether the permit triggers framing or waterproofing repairs. We write those items into the contract as allowances before work starts, so the price you sign is the price you pay. Call (813) 320-9346 for a free estimate with real numbers in writing.

FAQs - Impact Windows & Doors in Dunedin
Yes, in most cases it will. Replacing original jalousie louvers with impact-rated units is exactly the kind of upgrade a wind-mitigation inspector looks for, and the premium savings on a coastal Dunedin home are often substantial enough to recover part of the window cost within a few years. Call (813) 320-9346 and we’ll tell you what to expect before you commit to the job.
That’s exactly what we do. We measure every opening twice and inspect what’s behind the frame before we give you a price. If the wood buck is rotted or the opening is undersized, we write the framing repair into the quote as an allowance so you know the number before work starts. No surprises.
Because the old jalousie window never had any is the reason we include it. Decades of wind-driven rain off St. Joseph Sound wicks through the old sill pan and rots the sub-sill. Building code now requires proper flashing on impact-rated openings. We install butyl tape at the jamb and sill before re-stuccoing, so water can’t repeat the damage.
Usually not. Wind-mitigation credits in Florida are calculated based on how much of the home’s glazed area is protected and which openings meet the standard. Partial upgrades get partial credit, and in some cases the back-elevation openings are flagged during inspection. Call (813) 320-9346 and we’ll help you decide which openings make the biggest insurance difference for the least cost.
No. Fogged glass means the seal has failed and the insulating value is gone. It says nothing about whether the glass meets impact standards. Many older double-pane units in Dunedin are tempered, not impact-rated. If you’re in the Wind-Borne Debris Region, a fogged unit still needs to be confirmed against the Florida Building Code. We’ll tell you during the quote.
