CWS Windows & Doors in Casselberry, FL | TruePane Windows & Doors
We provide independent CWS window and door service across Casselberry, from single-hung rebuilds to full-frame impact replacements. We are not a CWS dealership and we do not claim manufacturer authorization. What we bring instead is years of hands-on CWS repair work in Central Florida, including the specific ways lake humidity and reflected sunlight beat up these units faster here than almost anywhere else in Seminole County. If you own CWS windows or doors in Casselberry and something is dragging, fogging, binding, or leaking, call (754) 238-2201 and we will give you a straight answer.
Why Casselberry Residents Choose Us for CWS Service
Most window companies in Seminole County will replace a CWS unit. Very few will repair one properly. That distinction matters in Casselberry, where a high share of homes still carry CWS windows installed in the 1990s and early 2000s, and where replacing an entire opening because a roller wore out is a waste of money most homeowners should not have to eat.
Dale Kessler, our owner, grew up in Kendall and learned window work the slow way, watching his father re-glaze storefronts along the Tamiami Trail before he ever saw a paycheck. He trained at Miami Dade College’s vocational program and has been measuring, sourcing, and setting windows and doors in Florida for going on three decades. His rule, the one he still enforces on every job we run in Casselberry, is simple: measure it right the first time, or plan on coming back. That is why we stock CWS-compatible rollers, balance springs, crank gears, and weatherstripping profiles that generic shops order in and wait on. We carry what the trucks are likely to need before we pull up.
We are a local company with years of community service behind us, not a franchise crew rotating through town. A live person answers our phone 24 hours a day. Our technicians are background-checked and uniformed, and they treat your home the way they would treat their own mother’s.

Common CWS Windows & Doors Problems We Solve in Casselberry
- CWS slider rollers and tracks wearing out from lake moisture and constant use. Casselberry homeowners open sliders for lake breezes more months of the year than almost any other inland community in Seminole County, and the humidity never really quits. The rollers flatten, the nylon tires crack, and the sash starts dragging or hopping off the track. We replace rollers with OEM-spec matching parts and recondition the track rather than telling you the whole door is done.
- Fogging and condensation between CWS double-pane glass. Around Lake Howell and Lake Concord especially, insulated glass seal failure shows up early and often. Persistent lakeside humidity pushes moisture into the airspace once the primary seal gives, and the result is the milky fog you cannot wipe off from either side. We rebuild sashes with matching OEM glass packs when the frame is still sound.
- Aluminum frame pitting and corrosion near weep holes and screw bosses. Homes within a few hundred feet of open water see salt-laden air and constant dampness eat at raw aluminum edges. We see pitting around the bottom corners and under the sill track on older CWS frames, which can eventually compromise the corner keys. Depending on severity, we will either treat and seal the frame or recommend replacement.
- CWS casement crank mechanisms binding and stripping. The grease in those operator gears hardens in Central Florida heat and gathers humidity-borne grit. The handle turns, the sash does not move, or the gear strips entirely. We replace the crank and gear assembly, and we use a lubricant rated for this climate so it does not seize again in two summers.
- Weatherstripping turning brittle and losing its seal. The UV index here is brutal on rubber and vinyl bulb seals, and lake-reflected light accelerates it further on certain exposures. When CWS weatherstripping flattens or cracks, the unit leaks air, whistles in wind, and lets moisture into the track. We replace it with OEM-matched profiles that keep the original fit and closure pressure.
CWS Service in Casselberry: What Local Conditions Mean for Your Equipment
Casselberry is one of Central Florida’s most lake-dense small cities. Lake Howell, Lake Concord, Lake Triplet, and several smaller basins sit inside roughly five square miles, which means a large portion of residential windows face open water. Not just near water, but facing it, with daily direct reflected sunlight coming off the surface at a low angle. That reflected light concentrates UV exposure on the lower sash and the bottom seal edges of CWS windows in ways we rarely see in Longwood or Oviedo. Over eight to ten years, a lake-facing CWS 700 Series single hung can develop a failed seal along the southern glass edge while the rest of the unit still looks new. Vinyl frames on that same exposure can warp slightly at the bottom rail. The moisture is constant. The light is relentless. The failure pattern is predictable.
Our crew replaced a fogged CWS 700 Series single hung on Seminola Boulevard near Lake Howell, where reflected lake light had degraded the southern seal edge within eight years. The original aluminum track was intact but the insulated glass unit had lost its argon fill, so we rebuilt the sash with a matching OEM glass pack and recalibrated the balance springs. A year later, the owner called back to have the neighboring picture window done, same seal path, same reflective exposure. That is not a coincidence. It is the pattern.
Key takeaways for CWS owners in Casselberry:
- Lake-facing CWS units fail faster than street-facing units, even if both were installed the same year.
- Reflected UV degrades lower sash seals and vinyl bottom rails before the rest of the window.
- Early seal repair is usually cheaper than waiting for frame damage to spread.
- Code requirements may force wider replacement when you pull a permit for other work.
CWS Models & Products We Service in Casselberry
We work on the CWS 700 Series Single Hung, the 7700 Horizon Sliding Window, the 7200 Casement Window, and the 4000 Awning Window. That covers most of the CWS product installed in Casselberry homes from the mid-1990s through the mid-2010s. For critical components, locks, hinges, weatherstripping, balance systems, we use genuine CWS OEM parts whenever they are available. For generic hardware like rollers, glazing beads, and certain operator gears, we use proven aftermarket parts that match original specifications and cost you less without changing the fit or finish. When a CWS model has factory-discontinued parts or has failed multiple times in the same opening, we will tell you straight whether repair still makes sense or whether full-frame replacement is the better money. We do not have a financial incentive to push replacement. We do have a financial incentive to keep you from calling us back for the same failure. Those two things work in your favor. For a complete list of what we service, including CWS sales & service across all model lines, that page has the details.

FAQs - CWS Windows & Doors in Casselberry
Casselberry’s lakes keep ambient humidity higher year-round than in drier inland suburbs like Longwood, and that humidity attacks insulated glass seals from the outside while air-conditioned interiors pull from the inside. The result is earlier seal failure and more persistent fogging between panes. The fix is usually a glass pack replacement, not a whole window. Call (754) 238-2201 for a free look at what is actually failing.
Sometimes. If the existing CWS frame is structurally sound and the opening allows the added weight and thickness of impact glass, we can rebuild the sash with an impact-rated insulated glass unit. If the frame is pitted, racked, or cannot carry the load, a full-frame replacement is the honest answer. We measure and tell you which path applies before you spend anything.
Yes, and Casselberry’s lake-adjacent blocks see it more than most. Humidity corrodes the roller axles, constant use for lake breezes flattens the tires, and the track accumulates moisture-borne grit. The result is a heavy sash that drags or derails. Replacing rollers early is a small job. Waiting until the sash jumps the track can turn it into a big one.
In most cases, yes to both. Casselberry follows Florida Building Code, and if the work changes the opening size, the glazing, or the structural attachment, a permit applies. When you pull a permit for a kitchen or bath remodel, the code official can require whole-house window replacement if existing units fail wind-borne debris design-pressure thresholds. We pull permits on every job that needs one, and our work passes inspection the first time.
Most likely, yes. The operator gear strips when the sash binds against hardened grease and humidity-grit, and the handle keeps turning while the arm no longer moves. We replace the crank and gear assembly as a set, and we use a lubricant that will not harden again in two Central Florida summers. If the sash itself is warped, that is a different conversation. Call (754) 238-2201 and we will tell you which one you have.
