Unilock Windows & Doors: The Fort Worth Owner’s Guide
We stock and install Unilock-compatible windows and doors throughout Fort Worth, with most replacement work running $4,500 – $15,000 depending on how many units are involved and what the existing frames look like. The typical owner calls us after noticing a door that no longer closes square, condensation trapped between panes, or hardware that binds no matter how it’s adjusted. You’re not imagining it: Texas heat and clay soil do a number on window and door assemblies, and when a Unilock product fails, it usually fails where the seal or the operating hardware meets the frame.
Which Unilock Models This Applies To
The compatibility question comes up on nearly every call, and the answer depends less on the model name printed on the sticker than on the letter code next to it. Unilock windows and doors have shipped into Texas under several series designations over the years, and the production year changes the glass pack thickness, the roller and hinge hardware, and the weatherstripping channel profile. Before calling, grab the label on the inside edge of the frame or the top of the door slab. It will show a series code and a manufacture date. That code tells us what was original, what aftermarket parts will genuinely fit, and when it’s smarter to replace the sash than to patch the seal a second time.
One gotcha we see regularly in Fort Worth: a Unilock window from a 2012 production run will look nearly identical to a 2020 unit, but the balance springs and corner keys are not interchangeable. We verify measurements at the site rather than trusting a parts diagram alone, because a quarter-inch difference in the glass pack or a slightly different roller shoulder means the new part goes in tight and fails early. Elmstead Remodeling Fort Worth is an independent service provider, not affiliated with Unilock, and we tell you plainly when an OEM part is the right call and when a quality aftermarket equivalent will hold up just as well at a better price.

Signs Your Unilock Windows & Doors Is Failing
- Condensation or fog between the glass panes. That’s a failed insulated glass seal. Once the desiccant inside the spacer is saturated, the unit cannot be resealed in the field. Replacement is the honest fix.
- A door that scrapes the threshold or won’t latch without lifting. This usually means the hinge screws have stripped in the jamb, or the slab has sagged from years of Fort Worth temperature swings. Longer screws or a hinge rebuild often corrects it before the frame is damaged.
- A window that suddenly drops when opened. The balance system has failed. Unilock windows from certain production years used a coil balance that loses tension in heat, and an old one can let the sash fall hard enough to crack the glass.
- Drafts you can feel around the edges on windy days. The weatherstripping has compressed past recovery. Replacement weatherstripping is usually a quick fix, but if the frame has shifted with the soil, the real cure is re-shimming and resealing the unit.
- Locking hardware that grinds or won’t turn. Fort Worth’s dust works into the gear mechanism, and once the internal parts wear, lubricant only buys a week or two. The part swaps out faster than most people expect.

AfterReplacement Cost & What’s Included
In Fort Worth, a single Unilock-compatible window replacement typically lands between $4,500 and $15,000 when it’s part of a larger window or door project, which includes the unit, installation, and haul-away of the old materials. A single entry door assembly with new hardware and weatherstripping runs lower, while a wall of windows or a multi-slide door system climbs toward the top of that range. The spread comes down to frame condition, the number of units, and whether we’re doing a clean pull-and-swap or repairing surrounding framing first.
Every quote is a written price before any work starts. You’ll see the part cost, the labor, and the disposal line-item, not a lump-sum number that shifts once the crew arrives. The 365-Day Done Right Promise covers the completed work: if it’s not done right, we make it right.
DIY or Call Us?
What you can safely do: check the label for the series code and manufacture date, measure the visible glass opening, and take photos of the failed hardware from a few angles. That information helps us bring the right part on the first visit. What we don’t recommend: prying old weatherstripping off a Unilock frame that’s already stressed, or attempting a balance spring swap without knowing the exact spring weight. A window sash under spring tension can release suddenly, and the glass is the first thing to catch it.
If the frame is solid and the failure is isolated to one part, the job is usually quick. If the frame has moved with Fort Worth’s clay, forcing new hardware into an out-of-square opening just means doing it twice. Call (682) 708-9180 and we’ll sort out which situation you have.
FAQs
How long do Unilock windows and doors last in Fort Worth? In our experience, the glass units typically perform for 15 to 25 years before the seals fail, while door hardware and weatherstripping need attention every 7 to 10 years under Texas sun and heat. Units on west-facing walls in Fort Worth fail faster than shaded exposures. Call (682) 708-9180 for an honest assessment of your specific units.
Can a failed Unilock part be repaired, or do you have to replace it? Hardware failures, hinge sag, and weatherstripping are usually repairable. Failed insulated glass, cracked balance systems, and twisted frames are typically replacement territory. We’ll tell you which side of the line your product falls on before you spend a dollar. Call (682) 708-9180 and we’ll talk through what you’re seeing.
How long does a Unilock window or door swap take? A single window replacement is usually a one-day job. Door hardware, weatherstripping, and balance replacements are often done in the same visit. Larger multi-unit projects take longer, and we schedule the noisy work outside school-pickup hours when families are still living in the house. Call (682) 708-9180 to get a written timeline for your project.
Do you stock Unilock parts on the truck? We keep the most common Unilock-compatible rollers, hinges, weatherstripping, and hardware stocked, and we also carry materials for KraftMaid, Cambria, and Silestone products. For larger glass packs or less common series parts, we order from our supplier with the exact code from your frame label. Call (682) 708-9180 and we’ll confirm what we can bring on the first visit.
