Jerith Home Additions & ADU: The San Antonio Owner's Guide
If you own a Jerith home addition or ADU in San Antonio and a door component has failed, here’s the straight answer: we carry Jerith-compatible hinges, latches, strike plates, and replacement door hardware, and most swaps run between $45000 and $130000 installed, depending on the addition’s scope and condition. We can usually get replacement parts matched to your Jerith model within 48 hours, and most hardware repairs take under two hours once the part is in hand. The typical way San Antonio owners discover a problem is a door that suddenly won’t latch, a hinge that’s sagging, or a latch bolt that grinds against the strike plate after years of Hill Country heat and humidity working on the metal.
Sawyer Remodel San Antonio is an independent service provider. We’re not affiliated with Jerith, but we’ve worked on enough of their additions and ADUs across San Antonio to know which parts fail and which replacements actually hold up. If you’re looking for someone who can diagnose the problem, source the right part, and install it without a second visit, you’re in the right place.
Which Jerith Models This Applies To
Jerith manufactures additions and ADUs in several series, and the hardware spec can vary between them. Most commonly in San Antonio we see the Jerith Series 20, Series 30, and the standard residential line, which share latch and hinge dimensions but differ in finish options and strike plate configurations. The quickest way to identify your part is to look at the hinge leaf for a stamped number, usually a four-digit code on the inside edge. If the stamp is worn off, measure the hinge height: Jerith residential hinges run 3½ inches tall, while the heavier Series 30 uses a 4-inch hinge with a thicker leaf that can’t be swapped for the lighter version.
One compatibility gotcha worth knowing: Jerith’s latch bolt throw is slightly deeper than a generic residential latch. That means a cheap aftermarket latch from a big-box store will bolt, but the deadlatch plunger won’t align properly, and the door will rattle or fail to stay closed. We stock OEM Jerith parts where it matters (latches, strike plates, and hinge pins) and use quality aftermarket equivalents only for cosmetic hardware like door pulls and kick plates. If you’re trying to match an existing finish, tell us the door’s year of manufacture and we can usually identify whether it’s Jerith’s bronze, silver, or white finish from the hinge pin alone.

Signs Your Jerith Home Additions & ADU Is Failing
- Door won’t latch without lifting the handle. The latch bolt isn’t lining up with the strike plate, usually because the hinge screws have loosened in the jamb or the addition has settled slightly. We tighten and shim the hinges before replacing any hardware, which fixes about a third of cases without needing new parts.
- Latch bolt grinds against the strike plate. This is almost always a worn strike plate lip, not a bad latch. Jerith’s strike plates are stamped steel, and after a few years of San Antonio’s temperature swings they develop a burr that catches the bolt. A $40 plate replacement usually solves it.
- Hinge is visibly sagging. When the top hinge pulls away from the frame, the door drops a quarter inch and the latch misses its pocket. The underlying cause is a stripped jamb screw, and the fix involves replacing the screw with a longer one that bites into the rough opening framing.
- Deadlatch plunger won’t depress fully. The deadlatch is the small plunger next to the main latch bolt, and it’s designed to prevent credit-card bypass. If it doesn’t depress when the door closes, the latch is too shallow for the strike, which means the wrong part was installed or the door was re-hung incorrectly.
- Lock works but the door rattles in the frame. This points to a bent hinge pin or a hinge leaf that’s lost its pintle (the connection between the two leaves). Jerith pins are brass, and they deform under repeated stress. Replacing the pin is simple; ignoring it eventually wears out the hinge leaf itself.

AfterReplacement Cost & What’s Included
For a Jerith home addition or ADU door hardware repair in San Antonio, you’re looking at $45000 to $130000 installed, and the range depends on what’s actually broken. A simple hinge pin replacement or strike plate swap lands at the bottom of that range, while a full hardware kit (hinges, latch, deadbolt, and strike plates) with new finishes runs higher. Labor is the same across the board: we charge a flat rate for the service call and diagnostic, then a per-part installation fee that’s spelled out on the written estimate before any work starts.
Every job includes the new part, removal of the old hardware, alignment and adjustment, and a test cycle to make sure the door opens, closes, latches, and locks correctly. We also torque-check the hinge screws and lubricate the latch mechanism before we leave. And because we work under The Relay Visibility Guarantee, you’ll get a written price before we start and a photo update when the work is done. If the same issue comes back within 365 days, the fix is on us under our 365-Day Done Right Promise.
DIY or Call Us?
If you’re comfortable with a screwdriver, you can safely check three things: whether the hinge screws are tight, whether the strike plate has any visible burr, and whether the latch bolt moves freely when you turn the handle. That’s the extent of safe DIY for Jerith door hardware. The risk comes when you try to replace a latch or hinge and the new part doesn’t align, because a misaligned latch will either bind or fail to secure the door, and an ADU door that won’t properly lock is a security problem, not a cosmetic one.
Inside an ADU, a malfunctioning door can also be a safety issue if it’s a fire-rated door with a self-closing mechanism. Tampering with those mechanisms without understanding the code requirements can leave the door non-compliant. If your Jerith addition door has a self-closing hinge or a fire label, call us at (432) 547-6806 before you touch anything. It takes us less time to fix it correctly than it takes you to undo a well-intentioned mistake.
FAQs
Most Jerith hinges and latches last 10 to 15 years in San Antonio, but the latch bolt usually fails first because it takes the brunt of every open and close cycle. The average residential door gets opened 8 to 12 times a day, and over a decade that’s more than 35,000 cycles on a stamped steel bolt. Hill Country heat also accelerates wear on the internal spring. If your door is 10 years old and starting to misbehave, replacing the latch assembly now is cheaper than repairing a damaged frame later. Call (432) 547-6806 for an exact quote.
Usually not. Once a latch bolt develops play in its housing or the internal spring weakens, the cost of rebuilding it exceeds the cost of a new part. The exceptions are strike plate burrs and stripped hinge screws, which we can fix without replacing anything. If you want to know which category your issue falls into, call us and describe the symptom; we’ll tell you over the phone whether it sounds like a repair or a replacement.
Most hinge, latch, and strike plate replacements take between 45 minutes and two hours once the correct part is in hand. If we need to order a Jerith-specific part, you’re looking at 48 hours for delivery and then the same install window. We carry common Jerith latches, strike plates, and hinge pins on the service truck, so roughly half of the San Antonio calls we run are completed same-day.
We stock the most common Jerith latch bolts, strike plates, and hinge pins on our service trucks, and we can source OEM parts for less common models within two business days. You don’t need to order anything yourself. If you’ve already bought a part and want us to install it, we’re happy to do that too, but we’ll verify the spec before we start to make sure it’s the right fit for your Jerith model. Give us a call at (432) 547-6806 and we’ll check our inventory before you make the trip.
If you’ve got a Jerith home addition or ADU door acting up in San Antonio, don’t wait until it won’t lock at all. Call Sawyer Remodel San Antonio at (432) 547-6806 and we’ll send a background-checked technician with the right parts on the truck. You’ll get a written price before any work starts, and we’ll make sure the door operates the way it did the day it was installed.
