Fast, Reliable Window Installation Across Westlake
Window installation in Westlake usually falls into two categories: replacing builder-grade impact windows that have failed early, or upgrading to a stronger product before another hurricane season. In this city, virtually every home was built after 2018 by Minto Communities, which means the baseline is already a code-mandated impact package. The work we do most often is correcting what that rapid build got wrong or didn’t seal well enough. We serve Westlake directly, with crews who know the Cresswind, Sky Cove, and The Hammocks phases by name, not just by GPS. If you’re seeing fogged glass, a sliding window that sticks, or water staining under a sill, call (386) 251-6745 and we’ll send someone who can diagnose it accurately the first time.
Why TruePane Windows & Doors Is Westlake’s Preferred Window Installation Company
Dale Kessler founded TruePane in 2008 on a rule that still governs every job we take: if the pane is not true, the job is not done. That matters in Westlake more than in most places, because the housing stock here is almost entirely Minto-built tract construction. We know which phases got inconsistent flashing tape at sliding window sills. We know which model types run tight on the rough opening. We know that a fogged double-hung in one Cresswind home often means the same failed insulated glass unit in forty neighboring houses built the same month.
Our Window Installation team works in this market every week, which means we carry the impact-rated products with Miami-Dade or Florida Building Code high-velocity approval that Palm Beach County requires in the wind-borne debris region. We do not try to sell Westlake homeowners a non-impact window to shave a quote, because that would not pass the permit inspection. Every quote is written line by line, with both manufacturer warranty layers registered before the truck leaves your driveway.
Homeowners in Westlake tell us the same thing: they already had impact windows, but the seal failed in year four, and the original installer is long gone. They want a company that will still answer the phone in ten years. That’s why we put the Done Right Promise on every job, in writing, with no paperwork fights. A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree. Not a callback form.
Our Window Installation Services in Westlake
We install, replace, and service the full range of residential windows across Westlake, but a few product types account for most of the work in this city’s housing stock.
Double Hung Windows
Double-hung windows are the most common product in Westlake’s Minto-built homes, and the one we replace most often. The builder-grade insulated glass units in these windows routinely develop seal failure and fogging within three to five years, driven by the high ambient humidity near the Loxahatchee wetlands. We replace them with impact-rated double-hungs from manufacturers like Andersen and Pella, set in a properly sealed and flashed rough opening. A standard double-hung replacement in Westlake typically runs $900 to $1,800 per window, depending on size and glass package.

Casement Windows
Casement windows give you the tightest seal of any operable window because the sash presses against the frame when locked, which matters in a climate that gets real wind. In Westlake, we often replace casements where the original aluminum frame has developed a leak at the jamb-to-sill joint, where the original sealant shrank under Florida sun. A properly installed impact casement from a manufacturer like Pella or ECO Window Systems runs roughly $1,100 to $2,200 per unit here.

Sliding Windows
Sliding windows are popular in Westlake’s floor plans, particularly in bedrooms and kitchens facing the side yards. The failure mode we see most is inconsistent flashing at the sill, which lets water migrate into the wall cavity during heavy storms. We remove the old unit, inspect and replace the flashing tape, reset the frame square, and install the new impact-rated slider. Sliding window prices in Westlake typically fall between $800 and $1,700 per window, with larger three-lite units running higher.

Awning Windows
Awning windows hinge at the top and open outward, which makes them a good fit for Westlake homes that need ventilation even during rain. We install them most often in bathrooms and over kitchen counters. Because they seal tightly and shed water well, they are a strong choice in a humid climate like this one. Expect to pay between $700 and $1,400 per awning window in Westlake, depending on the glass package and frame material.

Trusted Brands We Service in Westlake
We are an authorized installer for more than a dozen manufacturer lines, including, and ECO Window Systems.

We quote manufacturer lines side by side on paper, so you can see the actual difference in product, warranty duration, and price before you commit. No house-brand mystery units.
Common Window Installation Problems We See in Westlake Homes
- Fogged builder-grade insulated glass. Westlake’s humidity near the Loxahatchee wetlands pushes moisture into failed IG units fast. We regularly see fogging in windows that are only four or five years old, and the same failure often repeats across an entire phase of Minto construction.
- Water intrusion at sliding window sills. Flashing tape and sealant were applied inconsistently across rapid-build phases. When one home on a block shows staining under a slider, the house two doors down often has the same issue.
- Frame-to-rough-opening gaps. On some model types, the original aluminum frame was set into an opening cut too large, leaving gaps that the installer covered with trim instead of sealing. Over time, those gaps let air and moisture through.
- Jamb-to-sill joint leaks. Aluminum frames expand and contract under the Florida sun. When the original sealant shrinks, the joint at the bottom corner of the frame opens up. This defect replicates across many homes in the same construction run.
Pricing for Window Installation in Westlake, FL
A typical single window replacement in Westlake runs $800 to $2,200 installed, depending on the product type, size, glass package, and whether the frame-to-rough-opening gap needs correction. Double-hung replacements most often land between $1,000 and $1,800, while casements and large sliders trend higher. A full-house window package, which in Westlake usually means 12 to 20 openings, typically runs $18,000 to $45,000, and the spread depends almost entirely on the manufacturer line and glass spec you choose. What you will never see in our quote is a surprise line item for flashing tape, shims, or sealant, because we price those into every window up front.

FAQs - Window Installation in Westlake
If your home was built in Westlake after 2018, it almost certainly has impact-rated windows and doors installed to the post-2017 Florida Building Code for the wind-borne debris region, so you meet the code baseline. You would need to upgrade when the original units fail, and that is happening earlier than most homeowners expect. Builder-grade insulated glass in Minto’s rapid-build phases is fogging and losing its seal within three to five years, driven by the humidity off the Loxahatchee wetlands. A replacement only passes the permit inspection if it carries Miami-Dade or FBC high-velocity approval, so a non-impact unit is not an option in Westlake. Call (386) 251-6745 and we will inspect what you have and tell you honestly whether it needs replacement or not.
Fog between the panes means the insulated glass seal has failed, and in Westlake it is almost always a replacement, not a warranty claim. The original Minto-installed units were often covered by a short builder warranty that has typically lapsed by the time fog appears, and the manufacturer warranty on a builder-grade IG unit is usually five years on the seal, pro-rated and difficult to enforce across a house full of windows. We replace the failed sash or the entire unit with an impact-rated window and register both manufacturer warranty layers in writing before we leave. For an exact quote on your fogged double-hung, call (386) 251-6745.
Yes, you need a permit to replace windows in Westlake, because Palm Beach County and the city require that all replacement windows in the wind-borne debris region meet the current high-velocity code. We pull the permit on every window replacement job, and we schedule the inspection after the work is done. You don’t have to chase the building department, and a failed inspection is on us to correct. That is part of what a square deal means: the permit and the inspection are included in your quote, not an extra charge added later.
It can, but only if the new windows are documented as impact-rated and the installation passes the permit inspection. Some Westlake homeowners see a meaningful premium reduction or a wind mitigation credit after upgrading from builder-grade to a stronger impact product, but the insurer requires documentation. We provide a line-item receipt showing the manufacturer, the product approval number, and the permit inspection record, which is what your insurer needs to apply any credit. Call (386) 251-6745 for a quote, and we will make sure the paperwork is in order before the job closes.
Yes, and it is one of the most unusual things about working in Westlake. Because the city is almost entirely Minto-built from 2018 onward, with consistent product runs across each phase, a flashing or sealant defect at a sliding window sill or threshold often repeats across thirty to fifty homes built the same month. Our crew was called to a Westlake home in the Cresswind phase for a fogged double-hung; we found the builder-grade insulated glass seal had failed, a pattern we have since seen in dozens of neighboring units built in the same construction run. After removing the failed sash, we installed a Miami-Dade approved impact-rated double-hung with low-E glass and argon fill, flashed the rough opening with new flashing tape, and verified the frame-to-rough-opening gap was properly sealed. We’ve since recommended the same fix to over a dozen homeowners on that block. If several neighbors on your street have the same leak, call (386) 251-6745 and we will likely already know the failure pattern before we arrive.
