Unilock Windows & Doors: The Dallas Owner’s Guide
We keep common Unilock-compatible window and door hardware in stock in Dallas, and most replacement parts run between $45 and $260 installed for a single component, with full window or door swaps typically landing between $450 and $1,500 depending on the unit. Call (903) 326-8963 and we’ll match the part to your Unilock model, give you a written price before any work starts, and get the job done in one visit. Most owners discover a failed part the hard way: a window that won’t stay up, a door that drags against the frame, or a lock that suddenly fights the key. The good news is that Unilock parts are matchable when you know what to look for, and that’s where we come in.
Bradford Remodeling Co Dallas is an independent service provider, not affiliated with Unilock. We install and source parts for Unilock windows and doors alongside the other brands we stock: KraftMaid, Cambria, Silestone, Therma-Tru, and more.
Which Unilock Models This Applies To
Unilock windows and doors fall into a few recognizable series lines, and the compatibility question comes down to three things: the series label stamped on the frame edge, the glass unit thickness, and the hardware set. If you open the sash and look at the top edge of the bottom rail, you’ll usually find a white sticker or etched code that identifies the model and production date. That code is the fastest way for us to match a part. No sticker? We’ll measure the roller diameter on sliders, the balance shoe profile on double-hungs, and the hinge offset on casements.
One Dallas-specific compatibility gotcha: Unilock slider windows sold in the Texas market often use a 5/16-inch roller with a flared housing, while the same visual window sold up north uses a straight-housing roller. The part numbers are one digit apart, and homeowners who order the wrong one online end up with a roller that binds in the track within a week. We’ve corrected that exact mistake more times than we can count. On doors, the main variable is the threshold height: Unilock pre-hung units built for slab foundations in Dallas ship with a 5/8-inch lower threshold than units built for raised foundations.
Our parts position is simple: OEM when it matters for the seal or the lock, quality aftermarket when the OEM piece is just a commodity roller or strike plate. For weatherstripping, we insist on the OEM profile because aftermarket bulbs never seat the same. For rollers and balances, we use a Dallas supplier that machines to the same tolerances at roughly 60% of OEM cost. You’ll see both prices on the written estimate.

Signs Your Unilock Windows & Doors Is Failing
- Window drops or slams shut when you let go. This is almost always a failed balance shoe or a stretched balance spring in a double-hung. The spring is still holding some tension, but not enough to counter the sash weight. If you hear a snap and the window drops hard, the balance has fully released.
- Slider window or patio door drags or makes a grinding sound. Rollers lose their bearings or flatten on one side from Texas heat cycling. A round roller becomes an oval, and the weight of the panel rides on the housing instead of the wheel.
- Door latch or deadbolt won’t line up with the strike plate. In Dallas clay soil, door frames shift seasonally. If adjusting the hinges no longer helps, the door slab itself has likely sagged, and the fix is a re-hung slab or a replacement hinge set on the Unilock frame.
- Condensation or fog between the glass panes. The insulated glass unit (IGU) has lost its seal. Once the desiccant inside the spacer bar is saturated, the unit is done. You can’t reseal an IGU; it gets replaced with a matching Unilock-spec unit.
- Drafts or visible daylight around the perimeter. Weatherstripping has compressed or cracked, or the frame has pulled away from the rough opening. In Dallas, the annual temperature swing from 15°F to 105°F accelerates compression-set on foam weatherstripping, especially on west-facing openings.
Replacement Cost & What’s Included
Installed pricing for Unilock window and door parts in Dallas runs like this:
- Single roller replacement on a slider window or patio door: $45 – $95 installed
- Double-hung balance shoe and spring set (both sides): $90 – $180 installed
- Weatherstripping kit for one window or door: $60 – $140 installed
- Door hinge replacement and re-hang: $120 – $260 installed
- Full window replacement (mid-size, contractor-grade): $450 – $1,500 installed per opening
What moves the number is access (second-story windows cost more in time), whether the frame needs routing or shimming, and whether we’re replacing one roller or the full set on a patio door. Every estimate includes the part cost, the labor, and the disposal of the old component, written as separate line items. The 365-Day Done Right Promise applies to every repair and every install we do in Dallas: if the part or the work fails within a year, we come back and correct it at no charge. Straight number, real scope, no surprises on delivery day.

Some things are worth checking yourself before you call. If a slider is dragging, pull the panel up and look at the rollers: if they’re ovalized or the housing is cracked, you’ve found the problem. If a window is stiff, cleaning the track and applying a dry silicone spray sometimes gets another year out of the rollers. That’s about where safe DIY ends for most Unilock parts.
Double-hung balance systems hold tension, and unhooking a balance shoe without the right tool can send a steel spring across the room. Patio door panels weigh 80 to 140 pounds, and pulling one out alone is how disc injuries happen. If you’re not sure, don’t guess. Call (903) 326-8963 and we’ll come out, identify the part, and give you a written price on the spot. You’re not obligated to anything until you see it in writing.
FAQs
Rollers and weatherstripping typically last 5 to 8 years in Dallas, with west-facing windows wearing out on the short end because afternoon heat bakes the plastic components. Balance springs tend to last 10 to 12 years. Call (903) 326-8963 if you suspect a part is wearing out, and we’ll confirm before it fails completely.
Rollers and balances are non-serviceable, meaning we replace them rather than repair them. Door alignment issues can sometimes be corrected by hinge adjustment or shimming, which costs less than a full re-hang. We’ll tell you which route makes sense once we see the unit.
Most single-part replacements take 30 to 60 minutes once we’re on site. A full patio door roller set and realignment usually takes 90 minutes to two hours. We carry common Unilock-spec rollers, balances, and weatherstripping on the truck, so we handle the majority of jobs in one visit.
We stock the common parts: 5/16-inch flared-housing rollers for Texas-market sliders, balance shoes and springs for double-hungs, weatherstripping profiles, and hinge sets. Oddball items like custom IGUs get ordered with a 3 to 7 day lead time. Either way, you get a written price and a confirmed date before we start.
