Fast, Reliable Window Installation Across Dunedin
Window installation in Dunedin is a different job than it is twenty miles inland. The salt air off St. Joseph Sound eats aluminum frames, the Florida Building Code demands impact-rated glass or approved shutters on virtually every home, and much of the housing stock still carries original jalousie windows from the 1940s through 1960s. TruePane Windows & Doors has been replacing those windows in Dunedin with the same steady hand we bring to every job. If you’re planning an upgrade, a replacement, or a repair, call (813) 320-9346 and a live person will answer. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway.
Why TruePane Windows & Doors Is Dunedin’s Preferred Window Installation Company
We’re a second-generation glazier’s operation, founded by Dale Kessler in 2008 on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. That’s not a slogan. It’s the standard applied on the first visit and the baseline for every callback. Dunedin homeowners have asked us back for years because we handle the coastal conditions that generic installers miss. We know what salt air does to a west-facing window on a 1950s concrete block ranch near Edgewater Drive. We know which jalousie frames are worth retrofitting and which belong in a recycling bin. We also know that a live person answering the phone at 2 a.m. is what a homeowner wants when a storm is two days out. That’s just how we work, 24/7, no voicemail tree.
Our technicians are background-checked and uniformed. They work in your home the way they’d work in their own mother’s. When we quote, you’ll see manufacturer lines side by side on paper, not a sales pitch with a single number at the end. We are an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, PGT, and CGI. That matters in Dunedin, where impact-rated product approvals change by code cycle. We don’t guess. We confirm compliance and register both warranty layers in writing before we leave your driveway, under what we call The Keystone Standard. Then we back the workmanship with the 90-Day Done Right Promise: if it isn’t done right, we make it right, no paperwork, no arguing.
Our Window Installation Services in Dunedin
Casement Windows
Casement windows are a strong fit for Dunedin’s coastal climate because they seal tightly when closed, reducing air infiltration on the west and northwest sides where prevailing salt air pushes hardest. On concrete block homes off Bayshore Boulevard and the street-grid neighborhoods flanking the Pinellas Trail, we typically install casement windows with impact-rated glass and marine-grade hardware. The crank mechanism holds up better against rust than sliding tracks when the salt load is heavy. A typical casement window installation in Dunedin runs $650 to $1,250 per opening, depending on size and whether we’re installing PGT or Simonton product.

Awning Windows
Awning windows hinge at the top and open outward, which makes them a good choice for Dunedin’s afternoon rain showers. You can leave them cracked open for airflow without worrying about water pouring in. In the bungalow-style homes around downtown Dunedin, we often pair awning windows with fixed picture windows to create a clean, flood-resistant opening that still breathes. Expect to pay $550 to $1,100 per awning window in Dunedin, with labor and flashing included. Salt air doesn’t touch the hinges as often as it does on slider tracks, so long-term maintenance is lower.

Fixed & Picture Windows
Fixed and picture windows are a practical option for Dunedin homes where the view matters and the opening doesn’t need to operate. The catch is that fixed windows facing St. Joseph Sound or the Gulf still must meet the same wind-borne debris standards as operable windows. We install fixed picture windows with impact laminated glass from PGT or CGI that hold their clarity while meeting code. In Dunedin, a large fixed picture window typically runs $800 to $2,200 installed, depending on the glass package and the condition of the rough opening. When we pull an old aluminum frame out of a concrete block wall, we inspect the jamb and sill for the water staining that hides behind stucco. That check is standard on every job.

Single & Double Hung
Single and double hung windows remain the most common replacement in Dunedin’s 1940s and 1950s ranches. For older homes, we recommend double hung units with vinyl or fiberglass frames that resist salt corrosion better than the original aluminum. On a 1950s concrete block home near the marina, we replaced rotted aluminum single hung windows with double hung Simonton units and rebuilt the jamb openings before flashing. A typical single hung window in Dunedin runs $450 to $950. Double hung runs $650 to $1,300. The cost difference comes down to glass package, frame material, and whether the old jamb needs rebuilding after decades of moisture.

Trusted Brands We Service in Dunedin
We carry and install product from Simonton, PGT, and CGI, among more than a dozen manufacturer lines. For Dunedin specifically, we stock impact-rated Simonton lines with fast lead times because the demand for coastal compliance never really slows down. PGT makes several of the impact units we install on waterfront homes, and CGI’s laminated glass holds up well against corrosion concerns. When a Dunedin homeowner calls and says they need windows before a wind-mitigation inspection, we can usually have product staged within days, not weeks, because we know which lines our local distributors keep in stock. You’ll see every line item on paper before you sign.
Common Window Installation Problems We See in Dunedin Homes
- Salt-air corrosion on west and northwest elevations. Aluminum frames, sill pans, and hardware facing St. Joseph Sound pock and chalk within 10 to 15 years instead of the 20 to 30 you’d see a few miles inland. By the time a homeowner notices the frame pitting, the seal has usually failed and the sash is no longer squared in the opening.
- Original jalousie windows that fail wind-load testing. The 1940s through 1960s concrete block homes across Dunedin were built with louvered glass panels that don’t come close to current wind-load ratings. Citizens Property Insurance wind-mitigation inspections flag them regularly, and most policies require full replacement before renewal or sale.
- Improper flashing on concrete block openings. Water that gets behind stucco rots the wood jamb and sill without leaving an obvious exterior stain. Homeowners only notice when the window starts binding, the interior paint bubbles, or a musty smell settles into the wall. By that point, the framing repair is part of the job.
- Seal failure on double-pane units facing the water. Dunedin’s salt and humidity accelerate the wear on factory seals. Fog between panes means the insulating gas has escaped and the glass isn’t doing its job anymore. In most cases, the sash or the entire window needs replacement rather than a single-pane swap.
Pricing for Window Installation in Dunedin, FL
Window installation in Dunedin is priced by the opening, not by a flat rate. A typical replacement window project on a 1950s ranch here runs $4,500 to $18,000 depending on the number of windows, the frame condition, and whether you’re going with impact-rated glass. Casement windows run $650 to $1,250 per opening. Awning windows run $550 to $1,100. Fixed picture windows run $800 to $2,200. Single hung runs $450 to $950, double hung $650 to $1,300. The salt-air factor means we may need to rebuild a jamb or replace a rusted sill pan. That’s not a surprise line item. We scope the opening before we quote. Call (813) 320-9346 and schedule a free estimate. What we quote is what you’ll pay, in writing.

FAQs - Window Installation in Dunedin
Yes, you need either impact-rated windows or approved storm shutters in Dunedin. The entire city sits within Florida’s Wind-Borne Debris Region because of its exposure to St. Joseph Sound and the Gulf of Mexico one barrier island away. Impact-rated windows are often the better long-term play because they’re always in place, don’t require a homeowner to deploy shutters before a storm, and directly improve your wind-mitigation inspection results. Call (813) 320-9346 and we’ll quote both paths on paper.
That’s salt-air corrosion from St. Joseph Sound. West and northwest-facing windows take the brunt of it, and aluminum frames break down far faster in Dunedin than they do even a few miles inland in Clearwater or Safety Harbor. The pitting is only the visible part. The real trouble is what’s happening under the frame against the concrete block, where moisture gets behind the stucco and rots the jamb. Let us inspect the openings before the wall damage spreads. Estimates are free.
No. Jalousie windows from Dunedin’s 1940s through 1960s homes don’t meet current wind-load requirements, and calking them shut doesn’t change that. Citizens wind-mitigation inspections will flag them, potentially affecting your coverage. The right move is replacement with impact-rated windows that meet the Florida Building Code. On a job off Edgewater Drive, we pulled jalousie windows that had been silicone-caulked for decades and replaced them with Simonton impact-rated casements. The homeowner’s insurance premium dropped enough to offset the cost faster than most inland projects. We’ll quote the replacement honestly, with no fine print.
Yes, but the savings depend on what’s currently in the openings. If you’re replacing single-pane aluminum or jalousie windows, the difference is substantial. Dunedin’s cooling season runs from roughly March through November, and homes with single-pane openings lose conditioned air constantly. New low-E, insulated glass units with tight seals reduce that load. But don’t expect ENERGY STAR windows to overcome a leaking attic or uninsulated block walls. They help, and in some Dunedin homes we see cooling bill reductions of 15 to 25 percent after replacing old aluminum single-panes. For an exact quote on your openings, call (813) 320-9346.
In most cases, no. Fog between the panes means the factory seal has failed and the insulating gas has escaped. You can sometimes replace just the sash rather than the entire frame, but the glass unit itself must be replaced. Near the water in Dunedin, seal failure happens faster because salt and humidity stress the edge seals. We’ll look at the window and tell you whether it’s a sash-only swap or a full replacement. The inspection is free, and the quote is in writing.
If you’re planning window installation in Dunedin, call (813) 320-9346 to schedule a free estimate. A live person answers, day or night. We’ll measure every opening twice, quote your options on paper, and register both warranty layers before we leave. Done right. In writing.
