Unilock Windows & Doors: The Fresno Owner’s Guide
We stock and install Unilock-compatible windows and doors for Fresno homes, with most replacements running between $4,500 and $15,000 installed depending on count, size, and framing condition. You’ll typically have a written line-item price in hand the same day we measure. Most Fresno owners discover a failed Unilock unit the same way: a draft that wasn’t there last winter, condensation fog between the panes, or a door that suddenly needs a shoulder to latch.

Unilock windows and doors carry a reputation for solid extruded frames and decent thermal performance, but nothing survives forever. The San Joaquin Valley sun does real work on seals and weatherstripping. When a Unilock part fails, the fix is usually specific, and guessing with a generic replacement costs more in the long run. Curtis Lane has seen enough mismatched retrofit jobs in Tower District bungalows and River Park homes to know that the part number matters more than the brand sticker.
Which Unilock Models This Applies To

Unilock has run several window and door series over the years, and the compatibility picture is not as forgiving as some owners assume. The frames changed incrementally between production runs, which means a sash from a 2008 Unilock 7000 series will not drop cleanly into a 2017 7000 series frame without shimming that looks wrong and wears worse. We check three things before quoting: the manufacturing label etched into the frame or sash edge, the visible glass dimensions, and the frame pocket depth.
Here’s the gotcha we see regularly in Fresno: Unilock doors built before roughly 2012 used a hinge mortise pattern that later production changed by 3 millimeters. Three millimeters is nothing until you hang a new door panel on old hardware and the reveal walks. If you’re replacing glass only, we match the insulated glass unit by thickness and spacer profile, not just by width and height, because the wrong spacer puts the seal line in the wrong plane and you’ll see fog again inside two seasons.
We handle OEM Unilock parts when the series is still supported and the lead time is reasonable. When a Unilock part is discontinued or backordered eight weeks, we move to quality aftermarket equivalents with matching dimensional specs and equal or better U-factor ratings. You get the written spec on both options before a single tool comes out. We’re an independent Fresno contractor, not a Unilock dealer, so our interest is getting your opening sealed and operating, not clearing out somebody’s warehouse inventory.
Styles & brands we work with







Signs Your Unilock Windows & Doors Is Failing
- Fog or condensation between the panes. This means the insulated glass seal has failed. The desiccant inside the spacer is saturated, and no amount of wiping fixes it. The fix is a new matched IGU, not a band-aid defogging service that lasts one Fresno summer.
- The sash drags or binds when you open or close it. This is usually a balance or roller issue rather than a frame problem. When the balance cartridge wears out, the sash sits cocked in the track and the weatherstripping gets pinched, which then tears and leaks air.
- A door that needs a hip-check to latch. Hinge wear and frame settling compound over time. Shimming the hinge leaves a visible gap at the top of the door, and that gap is where your cooled air goes in July.
- You can see daylight around the weatherstripping. Weatherstripping is the cheapest part of the assembly and the first thing Fresno heat destroys. Once it’s flattened or cracked, the window may still operate fine but it’s leaking air at every edge.
- Water staining on the interior sill or drywall below. This one demands attention fast. Weep holes clogged with Valley dust plus a failed corner seal equals water tracking into the wall cavity, and by the time you see the stain, the damage underneath is often bigger than the window repair.

AfterReplacement Cost & What’s Included
Installed Unilock-compatible window replacement in Fresno runs $4,500 to $15,000 for a typical project of five to twelve openings. Door replacement, when framing and threshold work is included, trends toward the upper half of that range. Here’s the breakdown we give on every written estimate:

- Single hung or casement sash replacement: $450 to $900 per opening, parts and labor
- Full frame window replacement: $800 to $1,600 per opening, including nail fin, flashing, and interior trim
- Patio door panel replacement: $1,200 to $2,400, including roller, track, and weatherstripping
- Entry door slab and hinge replacement: $1,500 to $3,000, depending on sidelight configuration
The spread comes from size and condition. A standard 36-inch-by-60-inch window with clean framing and easy exterior access lands at the bottom of the range. A second-story opening with rotted substrate, missing flashing, and stucco repair hits the top. Every quote itemizes the parts, the labor, and the disposal. The 365-Day Done Right Promise covers the installation for a full year: if the window leaks, binds, or the hardware fails because of our workmanship, we come back and correct it at no charge. The estimate says what we build, and we build what the estimate says.
DIY or Call Us?
You can check the label and measure the visible glass yourself, and that helps us quote faster over the phone. You can also replace flattened weatherstripping on a sliding door track with a kit from a hardware store, though the Unilock profile is specific and generic strips never seat right. What you should not do is pull a full frame window or an entry door without an extra set of hands and a plan for flashing and water management. A window swapped in a day but flashed wrong becomes a $4,000 stucco repair two rains later.
Glass replacement is also not a casual weekend project. Unilock IGUs are heavy, the glazing bead is brittle after ten Fresno summers, and a cracked pane during a DIY swap turns a $600 repair into a $900 repair with blood involved. If you want to talk through what you’re seeing before you decide, call (559) 785-2712 and we’ll help you identify the part over the phone. If it’s a five-minute check, we’ll say so.
FAQs

Expect 15 to 22 years from the frame and 10 to 15 from the insulated glass unit here in Fresno’s heat. The seals fail before the frames do, and the UV load in the Central Valley is harder on weatherstripping than coastal fog would ever be. If your Unilock units are past the 20-year mark and the seals are going, you’ll likely get more value from full frame replacement than from piecemeal sash swaps. Call (559) 785-2712 and we’ll give you a straight read on which makes sense for your house.
Yes, when the failure is isolated to the glass unit, the balance, the roller, or the weatherstripping. A failed IGU is a straightforward swap on most Unilock frames without replacing the whole window. When the frame itself is warped, rotted, or the corner welds are cracked, repair stops making financial sense and full replacement is the honest call. We’ll show you the bad frame before we recommend pulling it.
Most single-opening replacements are done in half a day from setup to cleanup. A full-house window replacement of ten to twelve openings typically runs two to three working days with a crew of two or three. If the door replacement involves stucco patching or threshold height changes, add a day for the finish work.
We keep common weatherstripping profiles, balances, rollers, and standard-sized insulated glass units on the truck for same-week replacement. Model-specific Unilock hardware sometimes requires a factory order with a one-to-three-week lead time, and we’ll tell you that lead time in writing before you commit. We also maintain parts contact across the Garrison Partners network, so a discontinued Unilock part in Fresno often shows up from another location’s documented stock within days.
