Boxabl Windows & Doors: The Pomona Owner’s Guide
We stock and install Boxabl-compatible windows and doors across Pomona, with most replacement units running $450-$1,200 per opening installed depending on size and whether it’s a standard Casablanca window or the larger sliding door assembly. Most Boxabl owners in Pomona call us after noticing the symptom, not the part - a window that won’t stay latched in the Santa Ana winds, or a door that drags after the slab has settled through a wet winter. We carry the common sizes on our trucks and can usually measure, match, and install within a single visit.
Which Boxabl Models This Applies To
Boxabl’s Casablanca line ships with two window configurations: the standard 36″ x 48″ single-hung vinyl unit and the optional 60″ x 48″ sliding window pair. The entry door is a 36″ x 80″ fiberglass slab with a pre-hung steel frame, while the rear sliding door measures 72″ x 80″ and rides on a bottom-roller track system. The part number is stamped on the interior frame edge - look for a small white label starting with “BX-” followed by the dimension code. We’ve seen owners order the wrong roller assembly because Boxabl revised the track profile in late 2022; the pre-2022 units use a 1.5-inch roller housing, while current production uses a 1.25-inch housing that sits lower in the track. We verify this measurement on-site before ordering, since the OEM part runs $180-$240 and the wrong one won’t seat properly.
Rowan Construction Group Pomona is an independent service provider - not affiliated with Boxabl - and we source both OEM and quality aftermarket equivalents. For the vinyl window sashes, we typically use AmesburyTruth hardware, which matches the Boxabl spec at roughly 60% of OEM cost and carries the same 10-year warranty.
Signs Your Boxabl Windows & Doors Is Failing

- Window won’t stay latched or rattles in wind. The keeper has worn or the sash has dropped out of square. In Pomona, the Santa Ana gusts accelerate this - we see it most in units installed before 2021, where the nylon latch insert was a softer compound.
- Door drags at the threshold or sticks at the top. The slab has absorbed moisture and swollen, or the frame has settled with the slab. Boxabl’s fiberglass doors resist swelling better than steel, but the pre-hung frame can twist if the rough opening wasn’t shimmed properly during original install.
- Sliding door jumps the track or requires two hands to move. The bottom rollers have flat-spotted or the track has dented from debris. Desert dust from Pomona’s eastern edge works into the roller bearings and grinds them down over 18-24 months.
- Visible daylight around the frame perimeter. The sealant bead has cracked or the foam backer rod has compressed. This isn’t cosmetic - it’s how moisture gets in behind the siding and rots the OSB sheathing Boxabl uses in the wall assembly.
- Condensation between window panes. The insulated glass unit (IGU) has lost its argon fill and the desiccant is saturated. Once you see fogging, the thermal performance is gone; in Pomona’s inland heat, that means higher AC loads through summer.

| Component | Part + Labor Range | Typical Timeline |
|---|---|---|
| Standard window sash replacement | $450-$680 | 2-3 hours |

| Full sliding door replacement | $1,200-$2,100 | Full day |
The range depends on three things: whether we’re matching an existing opening or reframing, whether the rough opening needs repair from prior leakage, and whether you want the OEM part or the AmesburyTruth equivalent. Under Clause 1 of the Haven Standard, you get a written price before we start - every time, with a line-item breakdown of parts, labor, and any contingencies. Our 365-Day Done Right Promise covers the installation and hardware; the glass itself carries the manufacturer’s warranty, which we register for you.
DIY or Call Us?

There’s a short list of checks that won’t make things worse. Verify the latch is fully engaging - sometimes the strike plate has shifted 1/8 inch and needs the screws tightened. Clean the sliding door track with a dry brush and check for obvious dents. Look for the “BX-” label so you know what you’re ordering if you go that route.
What goes wrong fast: removing a pre-hung door without supporting the frame header, which can drop and crack the drywall corner bead. Or forcing a swollen slab to close, which splits the lock stile. The sliding door weighs 90-plus pounds and the rollers are under spring tension - not a great place to learn by doing. Measure twice, then we can talk. Call (626) 606-1081 and we’ll schedule a free estimate, bring the right parts, and handle the install with a documented photo record you keep.
FAQs
Vinyl windows typically hold up 15-20 years here, though the Santa Ana wind cycles and inland UV exposure can shorten that to 12-15 years if the west-facing units aren’t shaded. The fiberglass entry door should last 25-plus years; the sliding door rollers need service every 3-5 years depending on how much grit tracks in. Call (626) 606-1081 for an exact quote on replacement - estimates are free.
Hardware failures - latches, balances, rollers - can usually be repaired for $180-$340. Fogged IGUs and cracked frames require full replacement; there’s no field repair that restores the thermal seal. We assess this on-site and tell you which side of the line you’re on before quoting. Call (626) 606-1081 for an exact quote - estimates are free.
A single window replacement takes 2-3 hours; a pre-hung door or full sliding door unit takes a half to full day. We don’t rush the flashing detail - that’s where leaks start - and we photograph each step for your record. Call (626) 606-1081 to schedule.
We carry the common window hardware, roller assemblies, and weatherstrip profiles for both the pre-2022 and current track systems. Full door slabs and window units are ordered to spec after we measure, with a 3-5 day lead time for OEM or 1-2 days for AmesburyTruth equivalents. Call (626) 606-1081 and we’ll confirm what’s in stock for your model.
