AfterWindows & Doors Services in Casselberry, FL
Window and door work in Casselberry usually means one thing: a 1950s-to-1980s concrete block ranch with original single-pane aluminum or jalousie windows set straight into masonry. That’s the house we know best, and it’s the reason our crews carry shims, treated sill stock, and Seminole County permit paperwork on every truck. If you live between Lake Howell and Lake Triplet and your windows fog or your back door drags, call us at (813) 320-9346. We’ll send a background-checked, uniformed technician who measures every opening twice and gives you a written quote before any work begins.
TruePane Windows & Doors started with a second-generation glazier named Dale Kessler, who got tired of watching out-of-true installs void manufacturer warranties. Our rule is simple: if the pane is not true, the job is not done. That applies to a maintenance check and a full custom window package alike.

Why Casselberry Homeowners Choose TruePane Windows & Doors
Homeowners in neighborhoods like Lake Kathryn and Hollowbrook tell us the same thing: they want a company that answers the phone and stands behind the work. A live person answers our line 24 hours a day, seven days a week. Not a voicemail tree, not a callback form. When you call about a fogged Andersen sash or a PGT impact window that needs re-glazing, you talk to a person who knows the difference.
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, PGT, and ES Windows. That matters here because Seminole County requires a current Florida Product Approval number on every window and door we set. The wrong product, or an installer who doesn’t check approvals before quoting, means a failed inspection and a tarp over your opening. We quote manufacturer lines side by side on paper so you see exactly what you’re buying, and we register both warranty layers in writing before the truck leaves your driveway.
Dale Kessler founded this company on The Keystone Standard: both manufacturer warranty layers registered, durations stated, and a 90-Day Done Right Promise on every job. If it isn’t done right, we make it right. No paperwork fights, no arguing. That’s the standard on the first visit and the baseline for every callback.
Windows & Doors Services We Offer in Casselberry
Window Installation
We set new-construction and retrofit windows into CBS masonry openings, which is the real test in Casselberry. Every job includes moisture sealing around the frame, correct flashing, and the Florida Product Approval documentation Seminole County wants at inspection. Learn more about our Window Installation in Casselberry.
Door Installation
Entry doors, side doors, and French doors get the same treatment: treated sills, proper threshold height, and weatherstripping that won’t bind in July. We quote the full job, including any sill-plate repair, before we cut anything. Learn more about our Door Installation in Casselberry.
Window Replacement
Most Casselberry replacements involve pulling old jalousie or single-pane aluminum frames out of concrete block and building the new opening correctly. We measure twice, order the right glass package for the lake humidity, and set the unit level and plumb. Learn more about our Window Replacement in Casselberry.
Impact Windows & Doors
After the 2004 season, Seminole County enforces wind-load and impact-resistance requirements strictly. We quote Impact Windows & Doors in Casselberry from manufacturers like PGT and CGI with the product approval numbers printed on the estimate, so there are no surprises at inspection.
Energy-Efficient Windows
Energy-Efficient Windows in Casselberry with Low-E glass and proper weather sealing cut direct afternoon heat gain on west-facing CBS walls, which makes a real difference on Casselberry’s lake-humid days. We’ll show you side-by-side quotes from lines like Andersen and ES Windows so you can compare glass packages honestly.
Sliding & Patio Doors
Fogged or dragging Sliding & Patio Doors - Casselberry in older homes are common, and the fix often means more than swapping the panel. We check the bottom track, the threshold plate, and the sill underneath before we quote, because water wicking into the sill is the root cause more often than rollers.
Glass Railing Systems
For lakefront patios and pool decks around Lake Concord and Lake Howell, Glass Railing Systems - Casselberry give an unobstructed sight line and hold up under Florida sun. Each panel is cut and set to specification, with standoff hardware and a full manufacturer warranty on the glass and clamps.
Custom Windows & Doors
Odd-sized openings are the rule in 1950s CBS construction, not the exception. We measure and order custom units that fit the existing masonry cavity without cutting corners off the rough opening or padding the reveal with trim. The result is a true fit and a clean finish line.

Why Casselberry’s Climate & Housing Affect Windows & Doors
Casselberry sits ringed by lakes, including Lake Concord, Lake Howell, and Lake Triplet. That water keeps localized humidity higher than in drier inland suburbs, and the effect on windows and doors is not subtle. Wood door sills, exterior trim, and non-impact frames absorb that moisture and start to rot from the ground up. In the lakeside CBS neighborhoods near Lake Triplet and Lake Concord, ground moisture wicks up through slab edges and into door frames from the bottom, rotting out thresholds and sill plates on homes whose owners assume concrete block walls mean no moisture problems. A door that starts dragging across its threshold is often the first visible symptom of rot underneath. That’s why we quote combined threshold-frame-and-door replacement proactively in those lakefront blocks, and why we always check the sill before we give you a price.
Another local factor: the 2004 hurricane season reshaped Florida’s building code, and Seminole County enforces those wind-load and impact rules strictly. Charley, Frances, and Jeanne all made landfall that year, and the code changes that followed mean every window and door replacement in Casselberry triggers a permit and a product-approval inspection. You can’t skip that step here, and a contractor who tells you otherwise is setting you up for a code violation. We handle permits, pull the right product approvals, and pass inspection before we consider a job complete.
Pricing for Windows & Doors in Casselberry
The final cost depends on what’s in the opening, which is why we quote after measuring. That said, honest ranges help. A standard vinyl window replacement in a Casselberry CBS home typically runs $450 to $900 per unit, including mulling materials and proper masonry sealing. Impact-rated glass pushes that to $900 to $1,800 per unit, depending on size and product line. A new entry door, including sill repair, runs $1,200 to $3,500. Custom or oversized units go higher. We never give a change-order surprise: the written quote is the price, and if the job changes scope, you approve it before we pick up a tool. For a free, exact estimate, call (813) 320-9346.

What Casselberry Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L.
