Oldcastle Windows & Doors: The Orlando Owner’s Guide
Oldcastle window and door replacement in Orlando typically runs $450 to $1,800 per window depending on glass package, frame material, and whether the sash or the full unit needs replacing. We stock Oldcastle-compatible balances, tilt latches, weatherstripping, and aftermarket equivalents on our trucks, and most single-window swaps are done in one visit. The way most Orlando homeowners first discover a failed part is simple: the window won’t stay up, the door won’t seal against the afternoon rain, or the crank spins without moving the sash. What starts as a nuisance becomes a bigger problem in Florida’s humidity, where a gap in weatherstripping invites moisture into the wall cavity within a season.

Which Oldcastle Models This Applies To

Oldcastle has manufactured windows and doors under several lines over the years, including the Series 1900 and Series 6000 vinyl lines commonly found in Orlando homes built between 1990 and 2015. If you don’t know which series you have, look at the corner of the glass or the spacer bar between the panes for a faint etch, usually a code that starts with a letter followed by numbers. You can also remove the tilt sash (release the two top tilt latches and tip the sash inward) and check the metal or plastic tag on the frame edge.
The big compatibility gotcha with Oldcastle windows is the balance shoe. Oldcastle used both 2-inch and 3-inch coil spring balance systems across the same visual style of window, so two windows that look identical from the outside can take completely different parts. The coil diameter matters too: 3/8-inch coil balances are common on larger, heavier sashes, while 1/2-inch coils hold the big picture windows. Getting this wrong means the window either slams shut or won’t hold open. We match the balance by measuring the visible coil width and sash weight, not just the window dimensions. OEM Oldcastle parts are still available for many models, but quality aftermarket equivalents from manufacturers like Truth Hardware and Caldwell often match or exceed original specs, especially for balances and rollers. We’re an independent Orlando service provider, not affiliated with Oldcastle, which means we can recommend the best-available part rather than whatever the brand still lists.

Signs Your Oldcastle Windows & Doors Is Failing
- Window won’t stay open or creeps down slowly. This is almost always a worn coil spring balance. The coils lose tension over years of use, and in Orlando the issue shows up faster because window sashes get opened and closed year-round, not just a few months like northern climates.
- Air you can feel around the frame, or daylight visible at the corners. The weatherstripping and corner seals have compressed or torn. Once the seal fails, the air gap lets moisture in and conditioned air out, which you’ll see on your utility bill within two or three months.
- Condensation or fog between the glass panes. The insulated glass unit (IGU) seal has failed. This isn’t something you dry out or refill, and in Florida’s humidity the fog will turn to permanent mineral staining on the inside of the glass within a year.
- Crank operator spins without moving the sash. On casement windows, the gear inside the operator has stripped. Oldcastle casement units use a worm-gear operator, and once the gear teeth go smooth, the window is stuck in whatever position it’s in.
- Framing around the window or door shows dark spots or soft drywall. That’s moisture working its way down from the rough opening, usually because the flashing or exterior seal has broken down. By the time you see the stain on the inside, the water has already been wicking into the framing for months.

AfterReplacement Cost & What’s Included
For Oldcastle window and door work in Orlando, here’s the practical price picture:
- Balance replacement (per sash): $125 – $350 installed
- Tilt latch or lock replacement: $85 – $200 installed
- Weatherstripping replacement (per window): $90 – $250 installed
- Insulated glass unit replacement (per sash): $350 – $900 installed
- Full window replacement (per opening): $900 – $2,400 installed
- Patio door roller and track repair: $175 – $450 installed
What drives the range is the part itself and the labor to get to it. A balance swap on a ground-floor window is a 30-minute job. A second-story sash with a failed IGU takes longer, and the glass unit costs more because it’s ordered to the exact size of your existing sash. Every quote includes the part, labor, and cleanup, in writing before work starts. If the repair fails within 365 days, we come back and fix it at no charge under the Done Right Promise.

DIY or Call Us?
The one genuinely dangerous job here is messing with coil spring balances on a large picture window. Those springs are under high tension, and when they release, they release fast. I’d rather you not lose a finger over a $150 repair. What you can safely do yourself is clean the tracks, check that the tilt latches click in fully, and replace peel-and-stick weatherstripping on doors. If the sash is heavy, won’t stay up, or shows fog between the glass, that’s not a weekend project. Call us at (850) 427-6454 and we’ll match the part, give you a written price, and get the window working again, usually in one visit.
FAQs

Vinyl Oldcastle windows in Orlando’s climate realistically last 20 to 30 years for the frame, but the moving parts wear out sooner: balances typically fail at 10 to 15 years, weatherstripping at 8 to 12 years, and insulated glass seals at 12 to 20 years depending on sun exposure. East and west-facing windows, and windows without any tree shade, fail fastest because the afternoon heat attacks the seals. Call (850) 427-6454 for an exact assessment of your windows.
Most individual parts can be replaced without buying a whole new window, including balances, tilt latches, locks, rollers, and weatherstripping. The exception is a failed insulated glass unit, which gets swapped out as a complete sash or a new IGU, not patched. We always check the frame condition first because replacing a part on a frame with water damage would just fail again.
A balance or latch replacement takes 30 to 60 minutes per window, and we can usually handle several windows in a single visit. A glass unit replacement takes longer because the IGU is ordered to size, typically 5 to 10 business days, and then installation is another hour or two. We’ll give you a written timeline with the written price before any work starts.
Our Orlando trucks carry the most commonly needed Oldcastle-compatible balances, tilt latches, locks, rollers, and weatherstripping in standard sizes. For odd sizes or insulated glass units, we order the specific part and install it once it arrives. We also stock parts compatible with KraftMaid, Cambria, and Silestone products, so if one visit reveals a second issue, we can usually address it on the spot. Call (850) 427-6454 for a free estimate.
