Trusted Window Installation for Naples Homeowners
Window installation in Naples, FL typically runs $450-$1,400 per opening for standard retrofit work, with full-frame replacements and impact-rated units landing higher depending on the opening size and the manufacturer line you choose. Most single-opening installs are completed in one day by a two-person crew, and we quote the job on paper before any work begins. TruePane Windows & Doors has been serving Naples homeowners since Dale Kessler founded the company in 2008, carrying forward a glazing tradition that now spans more than 42 years. We measure every opening twice, register both warranty layers before the truck leaves your driveway, and stand behind the work with our 90-Day Done Right Promise. If you’re dealing with a fogged seal, a window that binds in July, or a frame that’s started to rot at the sill, call (239) 326-9942 and a live person will answer, day or night.
Naples is a specific place to install windows. Salt air works on aluminum and steel, afternoon thunderstorms test every flashing detail, and the summer sun finds every gap in a rough opening. We build every install around those realities because we live here and we plan to be here in thirty years. Our home page lays out the full scope of what we do, but the short version is this: if the pane is not true, the job is not done.

What Our Window Installation Service Includes
Every window we install in Naples gets the same treatment before it ever goes into the opening: the opening is measured twice, the existing frame and flashing are inspected for hidden rot or termite damage, and the manufacturer quote is laid out side by side on paper so you see exactly what you’re paying for. We don’t install a window until we know the rough opening is sound, because a square deal starts with a square opening. Below are the specific window types we install and what each one does for a Naples home.
Single & Double Hung Windows
Single hung windows keep the top sash fixed and let the bottom sash travel up and down; double hung lets both sashes move, which makes a real difference for airflow in a two-story Naples home. We install both styles and pay particular attention to the sash balance system, because a cheap balance is the first thing to fail when salt air and humidity start working on the hardware. Our crews set the jambs with shims at the sill and the head so the sash glides without binding, and we test every unit five full cycles before we pack up. Double hung windows in bedrooms are a practical choice for cross-ventilation on nights when the Gulf breeze dies off.

Horizontal Roller Windows
Horizontal roller windows slide side to side on tracks, and they’re common throughout older Naples neighborhoods like Naples Park and East Naples, where they were the standard for decades. We install them with new track and roller assemblies rather than reusing worn hardware, because a roller window that jumps its track is a safety issue and a sign of lazy installation. Our crews check the track level with a laser and set the sash so the rollers carry the weight evenly across their full travel. When the track is out of true by even an eighth of an inch, the window will always bind somewhere, so we correct the opening before the frame goes in.

3-Panel Sliding (3-Lite Roller) Windows
3-Panel Sliding (3-Lite Roller) Windows span wide openings and give you a clear view across the room, which is why they show up so often in lanai-facing walls and great rooms in the Vineyards and Lely Resort. We install them with interlocking meeting rails and a continuous sill that drains properly, because a three-lite slider with a sagging center panel is almost always a drainage failure waiting to happen. Each panel gets its own roller assembly rated for the glass weight, and we set the panels in sequence so the reveal lines are consistent from top to bottom. Done right, a three-panel slider should open with two fingers on the pull handle.

Casement Windows
Casement Windows crank outward on side hinges and seal against the frame with a compression gasket, which makes them the tightest-operating window against wind-driven rain. That matters in Naples, where a summer squall can push water horizontally against a west-facing wall for an hour at a time. We install casements with multipoint locking hardware and check that the sash seals evenly around all four sides before we call the job done. For homeowners in North Naples and Bonita Springs who want maximum daylight with the window closed, a casement gives you the glass area of a picture window with the operability of a vent.

Awning & Hopper Windows
Awning & Hopper Windows are workhorses for small openings where you want ventilation without the swing clearance of a casement, with awnings hinging at the top to swing outward and hoppers hinging at the bottom to tilt inward. We install both types in bathrooms, utility rooms, and above kitchen sinks across Naples, always with attention to the hinge loading because a small window with a heavy sash wears out cheap hinges fast. Our crews bed the frame in sealant and set the sash so the gasket compresses evenly, which is the difference between an awning window that drips and one that holds dry through a tropical storm. These small windows get the same two-measure process as a full wall of glass.

Picture & Fixed Windows
Picture and fixed windows don’t open, and that’s the point: they’re built to give you an unobstructed view with the best thermal performance possible because there are no sashes, tracks, or meeting rails to leak air. We install them in Naples living rooms, stairwells, and gable ends where the view is the feature and the opening doesn’t need to vent. Our crews set fixed windows with the same flashed and shimmed reveal as any operable unit, and we spec insulated glass with a Low-E coating appropriate for the exposure. A fixed window done wrong is a leak and a fogged seal in three years; done right, it’s the quietest, most efficient window in the house.

Brands We Service for Window Installation
We’re an authorized installer for more than a dozen manufacturer lines, and that matters when it comes to warranty work. If a manufacturer finds the install was the problem, they’ll point at the installer; if the installer isn’t authorized, the homeowner is left holding the bag. We register both warranty layers in writing before the truck leaves the driveway, under The Keystone Standard, so you know exactly what’s covered and for how long. When we quote a job, we quote manufacturer lines side by side on paper, including PGT, ViewLux, and Mr-Glass, so you can see the price difference between an impact-rated PGT and a standard ViewLux in the same opening.
We’ve installed hundreds of PGT units across Naples and Marco Island, and we know their impact glass packages and their warranty registration process inside out. ViewLux is a strong value line for homeowners who want a tight, well-built window without paying for the impact rating they don’t need on an interior wall or a second-story gable. Mr-Glass and Therma-Tru come up often on retrofit jobs in older Naples homes where the rough openings are standard sizes and the homeowner wants a solid, no-surprises replacement. Whatever line is on your wall or in your quote, we install it to the same standard: if the pane is not true, the job is not done.
Signs You Need Window Installation Right Now
- Fogged glass or condensation between the panes. When a sealed unit fails, the inert gas between the panes leaks out and moisture moves in, which means the insulating value is gone and the view is permanently clouded. You can’t repair a failed seal; the glass unit has to be replaced, and if the frame is aged, a full new window install is often the better money.
- Windows that bind, stick, or won’t stay open. A sash that needs two hands to open or a double hung that drops shut on its own is telling you the balance system or roller hardware is failing. In Naples, where humidity swells wood frames and salt air corrodes metal parts, this is a progressive problem that gets worse every season.
- Daylight visible around the sash or frame. Look at the window from inside, lights off, mid-day: if you can see light around the edges while it’s closed, air is moving through the same gaps. That’s your HVAC bill leaking out of the house, and it’s the most common sign that a retrofit insert can’t solve the problem and the window needs to come out.
- Soft wood, peeling paint, or mildew at the sill. Water has been getting behind the frame somewhere, and by the time you see it on the interior, the damage is usually well underway. Naples windows see hard downpours and high humidity, so sill rot is a structural issue, not a cosmetic one.
- Windows rattling in the wind or leaking during storms. Loose hardware, worn weatherstripping, or a frame that’s pulled away from the house will let wind-driven rain find its way inside. If you’re putting towels down during a summer storm, call us at (239) 326-9942 before the next system rolls in.
Our Window Installation Process - Step by Step
We keep this process visible because a window install done right is a sequence of deliberate steps, not a flurry of activity. Here’s exactly what happens on a TruePane window installation in Naples:
- 1
Double measurement and opening inspection. Every opening gets measured twice, by the same technician, with a steel tape and a laser. We also probe the sill and the jamb for hidden rot before we order or cut anything, because no manufacturer warranty covers a window set into a compromised opening.
- 2
Side-by-side written quote. We quote the manufacturer lines that fit the opening side by side on paper, with the glass package, frame material, and warranty durations stated. You see exactly what you’re buying, and the price on the quote is the price on the bill.
- 3
Removal and full opening prep. The old window comes out, and we get down to bare framing. Damaged wood gets repaired or replaced, the rough opening gets shimmed square and level, and the sill is flashed to shed water away from the house. We don’t set a window over rot or standing water.
- 4
Setting, leveling, and sealing the new unit. The new window goes in plumb, square, and true, with shims at the sill and head so the glass carries no load. We seal the perimeter with closed-cell backer rod and high-grade sealant, and we flash the exterior to tie into the existing weather barrier.
- 5
Cycle testing and warranty registration. Every operable window gets cycled open and closed five times, and the reveal lines are checked with the eye and with a level. Before the truck leaves, both manufacturer warranty layers are registered in writing and the duration is stated to you plainly. Then we walk you through the finished install and answer whatever questions you have.
If a step looks quick on paper, it’s because the preparation was already done. We leave the job site swept, the old window hauled away, and the new unit working the way it was designed to work. That’s the 90-Day Done Right Promise, and it’s the least we offer.
How Much Does Window Installation Cost in Naples?
A typical single hung or horizontal roller retrofit in Naples runs $450-$850 per opening, depending on the glass package and the condition of the existing frame. Casement and awning windows run $600-$1,100 per opening, and a three-panel sliding window runs $1,200-$2,400 installed due to the wider span and heavier glass. Picture and fixed windows track with their size: a standard 4-by-5 picture window typically installs for $550-$1,000, while an oversized fixed unit with tempered glass climbs from there. Bay & Bow Windows start around $2,500 and go up based on the projection depth and the seat framing required. Impact-rated glass adds $250-$600 per opening over standard insulated glass, and full-frame replacement adds $150-$400 per window over a retrofit insert because the old jamb and trim come out and new flashing goes in.
What moves the price: the age of the house, the condition of the rough opening, whether the existing window is a standard size or a custom cut, and whether the opening needs structural repair once the old unit comes out. Older Naples homes with wood frames built before current wind codes often need sill repair, and we’ll show you that on the written quote before we order anything. How to avoid overpaying: get the quote in writing with the manufacturer and glass package named, ask whether the warranty will be registered in your name and for how long, and refuse any bid that won’t tell you exactly what’s being installed. Our free estimate includes a full inspection of every opening, a written line-item quote, and both warranty layers stated in writing before you sign anything. Call (239) 326-9942 and a live person will schedule the visit.

Frequently Asked Questions - Window Installation in Naples
Window installation is the process of setting a new window unit into a rough opening in your home’s wall, leveling and squaring it, sealing it against water and air, and trimming it out to finish the interior and exterior. A proper install includes inspecting and repairing the rough opening, flashing the sill, shimming the frame plumb and true, and sealing the perimeter so that no water or air moves through the gap. Installation quality is the difference between a window that performs for thirty years and one that fogs, binds, and leaks inside of five. Call (239) 326-9942 for a free written estimate on any window in your Naples home.
A single window replacement in Naples typically takes two to four hours from setup to final cleanup, and most single-day jobs are completed in one visit. A full house of ten to fifteen windows usually takes two to three days depending on the condition of the rough openings and whether any structural repair is needed once the old units come out. We schedule our crews in advance and we tell you plainly when we’ll arrive and how long the work will take. If the scope changes, we put it in writing before we proceed, and the price on the quote is the price on the bill.
You can expect to pay $450-$1,400 per opening for a standard retrofit window installation in Naples, with impact-rated glass and full-frame work running higher depending on the manufacturer and the size of the opening. Three-panel sliders, bay and bow windows, and custom-sized units all land above that range due to the additional framing and glass handling involved. The only way to get an accurate number for your home is a written quote based on a physical inspection of your openings. Our estimates are free, and we show you the manufacturer line, glass package, and warranty period on paper before you decide.
Yes, we’re an authorized PGT installer and we work on PGT windows throughout Naples and Collier County.

A window that’s shattered by a storm, a branch, or a break-in is an emergency, and we respond to those calls day or night. A live person answers the phone at (239) 326-9942 twenty-four hours a day, seven days a week, and we’ll get a crew scheduled to secure the opening as soon as possible. For non-emergency installations, we schedule in advance and we arrive when we say we will, which is a promise we put in writing on the work order. If you’ve got a broken window in Naples right now, call now.
Under The Keystone Standard, every TruePane install includes both manufacturer warranty layers registered in writing, with the durations stated plainly, before the truck leaves your driveway. The manufacturer covers the glass and frame per their warranty terms, and our workmanship is guaranteed under the 90-Day Done Right Promise: if it’s not done right, we make it right, with no paperwork fights and no arguing. We don’t hand you a warranty booklet and wish you luck. We register it, we explain it, and we stand behind it.
Clear the area inside and outside each window by about three feet: move furniture back inside, and pull plants or decor away from the exterior wall so the crew has a clean working space. It helps to take down curtains or blinds at the windows being replaced, and if you have pets, keep them in another room while we’re working. We bring our own drop cloths and we clean up after ourselves, so you won’t be vacuuming drywall dust out of the carpet when we leave. If anything comes up during the day, the crew lead will talk to you directly, no voicemail tree involved.
