Deadbolt Adjustment Service in Cypress, TX 77433
A deadbolt that needs a shoulder, a lift or three attempts is almost never a broken lock. It is a door that has moved a few millimetres away from where the bolt expects to find the strike. In the newer half of Cypress that movement is routine: expansive clay under the slab, a foundation still finding its level, and a humidity cycle that works on every wooden jamb in the house. Adjustment fixes it. A new lock in the same opening does not.
Start here: throw the bolt with the door wide open
One test splits every deadbolt complaint into two completely different jobs, and it takes ten seconds.
Swing the door wide, so the bolt has nothing at all to enter, and turn the thumbturn through its full travel. Compare that against how it feels with the door shut.
- Smooth open, stiff closed. The lock is healthy. The bolt and the hole it aims at no longer line up, and everything that follows is alignment work on hinges, jamb and strike.
- Stiff either way. Now it is the mechanism: a worn cylinder, a bent tailpiece, or a lock body torqued so hard on installation day that the two halves pinch the bolt tube.
The large majority of calls we take in 77433 land in the first group. That distinction matters, because the instinctive response is to buy a replacement deadbolt, and a new lock fitted into an unchanged opening reproduces the identical symptom inside a week.
Why entry doors in 77433 come out of alignment
This ZIP covers the newest part of Cypress — Bridgeland, Towne Lake, Cypress Creek Lakes, Fairfield and the subdivisions filling in either side of the Grand Parkway. The stock is overwhelmingly post-2000, much of it post-2010, and that age profile produces a specific failure pattern.
- A slab still finding its level. New construction over Gulf Coast clay does most of its settling in the first few years. A front door hung perfectly at closing can be millimetres out by its second summer, and the bolt reports it first because it has the tightest tolerance on the door.
- Heavy doors. Eight-foot slabs, glass-heavy fronts and double doors with sidelights are common here. More weight on the top hinge means faster sag, and sag always presents as a bolt arriving low at the strike.
- The garage entry door. Garage pads and house slabs are poured separately and settle at different rates. That door is the most common second item on our tickets.
The plate, the pocket behind it, and the screws nobody looks at
The plate
Read the bolt first. A polished stripe along its top or bottom edge tells you which way it is arriving. For a direction and a distance rather than a guess, smear marker on the end of the bolt, throw it against the closed strike, then open up and read the transfer mark on the plate. Small errors come out with a file. Larger ones mean the plate physically moves.
The pocket
Behind the plate is the pocket, bored into the jamb and ideally through into framing. A residential deadbolt is built to throw a full inch. Shallow, foam-packed or never bored to depth, and the bolt stops short — it feels stiff, it reads as locked, and it holds with a fraction of its designed resistance. Restoring full throw is often the most valuable thing done on the visit.
The screws
The two short screws packed with a deadbolt bite three-quarters of an inch of soft jamb pine. Real resistance comes from long screws that cross the shim space into structural framing. That swap is the biggest security gain available on an existing door, for the price of the screws.
Half of these faults are fixed on the opposite edge of the door
A door hangs on three hinges and the top one carries most of the load. Its screws sit in end grain and shim space, and under a heavy slab they gradually back out. The door drops at the latch edge, the bolt starts arriving low, and the homeowner’s description becomes: it only locks if I lift the handle while I turn it.
The correction is upstream. One or two screws in the top hinge are replaced with fasteners long enough to reach the jack stud behind the jamb, then drawn up progressively. The door lifts back towards where it was hung and the bolt finds its pocket again with nothing altered at the lock end.
Order matters. Filing a strike to suit a sagging door permanently records the sag in the hardware, so the hinge side is always addressed first. While we are on that edge we also check for leaves not seated flat in their mortises, a middle hinge drawn tighter than the other two and pulling the door out of plane, and paint build-up on refinished doors.
Motorised deadbolts: why alignment decides your battery life
Much of our 77433 work is access control, so many of these calls involve a motorised deadbolt. Alignment matters far more there: your wrist produces vastly more torque than a small motor running from four AA cells.
- Battery life is an alignment readout. A lock rated for months that needs cells every few weeks is fighting a misaligned strike on every cycle. Correct the alignment and runtime generally returns near the published figure.
- Auto-lock exposes the fault. A hand-operated lock silently gets a helpful nudge from the person using it. Auto-lock fires with nobody there to lift the door, so a door that always locked fine starts leaving itself open the week the feature is enabled.
- Recalibrate after anything moves. These locks learn their stop positions during a calibration routine. Move the strike or reseat the interior assembly without rerunning it and the lock spends its life aiming at a position that no longer exists.
We also check what the lock talks to. A deadbolt depending on a hub two floors away across a large floor plan reports its state unreliably — a wireless coverage problem, and we say so rather than adjust hardware that is already correct.
What you can reasonably handle and what needs a van
A good deal of this is a homeowner job, and we would rather say so than sell a visit you do not need.
Reasonable to do yourself
- Tightening hinge screws and swapping short strike screws for long ones into framing.
- Marking the bolt and reading the transfer to learn which direction the error runs.
Worth a professional
- The pocket needs deepening or re-boring — a bit that wanders exits through the jamb and shows on the brickmould.
- The plate must move, meaning old screw holes are plugged and glued before new ones are drilled, or the bit chases the plate straight back.
- A hollow metal jamb, a commercial opening or a fire-rated door, where pocket and reinforcement are part of the assembly’s rating.
- Any door with a visibly tapered gap at the head or latch edge. That is a hanging fault; adjusting the lock only hides it.
Two jobs we do not take: rekeying, master keying and lockouts belong with a licensed locksmith, and a slab that is delaminating or racked in its frame belongs with a door and millwork contractor. You hear that on site rather than get a repair that cannot last.
How an EVOTECH alignment call runs, step by step
- Open-door test on every lock on the ticket, separating mechanism faults from alignment faults before anything is loosened.
- Hinge side before strike side. Short or loose top-hinge screws are replaced into framing and the door drawn back up first.
- Transfer-mark the bolt, so the remaining error is a direction and a distance rather than an opinion.
- Correct at the strike: file the opening, shim behind the plate, plug and re-drill for a relocated plate, or open the pocket to full throw.
- Upgrade the fasteners, shimming any void behind the jamb so long screws pull against something solid.
- Record what moved, so the next person at that door knows the strike was relocated and does not read it as a factory defect.
What changes the scope of the work
Every visit opens with a free on-site estimate and an itemised quote before work begins. We will not price a door over the phone: the gap between a ten-minute correction and an hour of jamb work is invisible from a description. What moves the number:
- How many doors. Front, back, garage entry and a side door usually drift for the same reason and cost far less handled together.
- How far out the bolt is. Filing is quick; relocating a plate with plugged and re-drilled holes, or opening a shallow pocket, is not.
- Motorised lock work, including refitting the interior assembly, recalibrating and verifying the bridge actually reaches the door.
Five mistakes that bring somebody back a second time
- Filing the strike on a sagging door. It buys a fortnight, then the slab drops further and the opening is too generous to hold the bolt squarely.
- Long screws into an unshimmed void. The jamb bows inward, the stop moves with it, and now the latch is out as well as the deadbolt.
- Replacing the lock instead of fixing the opening. The fault returns and the paperwork blames hardware that was never faulty.
- Skipping recalibration. The strike moved, the motor never learned it, and the lock burns batteries reaching for a stop that is gone.

Frequently asked questions
My deadbolt only locks if I pull the door towards me first. Is the lock failing?
Almost certainly not. Pulling the door towards you moves the bolt relative to the strike, which tells you both that the error runs along that axis and how you have been compensating for it. Mark the bolt, read the transfer, correct it there.
Would buying a better deadbolt fix this?
Rarely. A higher grade brings a stronger bolt, a better cylinder and usually a box strike — all worthwhile, none of which relocates the hole in your jamb. Fit an excellent lock into a misaligned opening and you get the same stiffness with a better warranty.
It was perfect all winter and started sticking in July. Nothing was touched.
That is the classic Cypress seasonal signature. The clay under a 77433 slab holds water through a wet spring and contracts through a hot, dry summer, so the house moves on an annual cycle. Nobody changed anything; the building did. A correction sized for the extremes, not for the weather on the day of the visit, is the point of doing it properly.
My smart lock keeps eating batteries. Is that the lock or the door?
Check the door first. If the bolt throws easily in free air but the motor labours with the door closed, every cycle is a partial stall and the current draw reflects it. Fix the alignment, rerun calibration, then measure runtime again before buying a replacement unit.
Do the long security screws come as part of an adjustment visit?
Yes, on any door where the jamb can take them safely. We shim the void first so the fastener pulls against something solid, then drive into framing. It belongs in the same visit as the alignment, not a separate trip.
