Door Lock Repair
Usually the door moved, not the lock
Deadbolts you have to lift the door to turn, latches that miss the plate, handles that spin, and doors you have quietly stopped locking because it is too much effort. We fix the hardware and the alignment behind it.
Two halves that have to meet, on a door that keeps moving
Understanding this is the difference between a twenty-minute repair and buying hardware you did not need.
Every door lock is two separate components. On the door there is the lock body — a deadbolt, a latch, a mortise case or a multi-point mechanism. On the frame there is the strike plate and the mortice behind it, the hole the bolt has to enter. The lock only works when those two line up within a couple of millimetres.
That tolerance is the whole story. A deadbolt does not gradually wear out; it either enters its hole cleanly or it binds against the edge of the strike. So when a lock that worked for fifteen years suddenly needs the door lifted, the mechanism is almost always fine. The door has dropped on its hinges, or the frame has moved, and the bolt is now hitting metal instead of entering the hole.
Which is why fitting a new lock to a misaligned door fails. The new deadbolt hits the same misaligned strike and binds identically within a week. The repair is geometric, not mechanical.
We are a repair and alignment service rather than a locksmith. If what you need is rekeying, key cutting or a lockout, we will tell you plainly and point you somewhere useful rather than take the job.
A lock you have to fight is a lock that stops being used
The pattern we see constantly is a back door or a patio slider that became awkward to lock, then difficult, then simply stopped being locked at all. That is the real cost of a misaligned bolt, and it is why we treat these as worth doing properly rather than as trivial jobs.
In Delaware the movement behind it is seasonal and predictable. Humid summers swell doors and jambs; dry heated winters shrink them back. A strike set perfectly in February can be noticeably out by August, and in an older home that has been happening for a century.
On the coast there is a second cause: salt. It corrodes cylinders, bolts and the screws holding strikes in place, so hardware that would merely stiffen inland can seize entirely within sight of the water.
The most common lock repair we carry out involves no new lock at all.
Lock and hardware work we handle
Entry doors, back doors, patio doors and interior doors alike.
Deadbolts
Bolts that stick, bind, will not throw fully or need the door lifted. Repaired, realigned or replaced.
Strike plate alignment
The most common fix of all. Repositioning or rebuilding the strike so the bolt meets it cleanly through the seasons.
Handles, levers and knobs
Spinning handles, stripped spindles and levers that no longer spring back.
Mortise and period locks
Original lock bodies in older Delaware homes, stripped, cleaned and rebuilt where possible.
Patio door locks
Slider latches, foot bolts and auxiliary locks on the most common point of forced entry.
Security upgrades
Reinforced strikes, long screws anchored into framing rather than jamb trim, and secondary locks.
The problems Delaware door locks have
Seasonal movement, salt air and a lot of rental turnover.
A house that moves twice a year
Delaware's humidity swing is large enough to shift a door several millimetres between winter and summer. A strike positioned for one season is out of register in the other, which is why so many doors here lock easily in spring and stubbornly in August.
Salt corrosion on the coast
Along the bay and the Atlantic, salt attacks cylinders, bolts, springs and fixings. A lock that is merely stiff in Dover can be seized solid in Rehoboth, and the small screws holding a strike plate are usually the first thing to go.
Rentals, turnover and security
The coastal counties carry a large stock of seasonal rentals and second homes, and the northern towns have dense housing where ground-floor security genuinely matters. In both cases a door that will not lock properly is more than an inconvenience.
Why call us rather than just buy a lock
We treat it as a door problem, which is what it almost always is.
Diagnosis before hardware
A new lock on a misaligned door binds just as badly. We fix the geometry first and replace hardware only when it is genuinely worn out.
Period hardware preserved
Original mortise locks are usually rebuildable, and they are better made than what would replace them.
An honest security view
We will tell you plainly where a door is weak and what would actually make a difference, rather than selling you the most expensive lock on the van.
Small jobs welcome
Strike realignment is often a short visit, and we are happy to do short visits anywhere in the state.
Three steps, no runaround
Tell us what the lock does
Whether you lift the door, jiggle the key, or shoulder it closed — those details point straight at the cause.
We check the door, not just the lock
Hinges, slab, frame and strike, then a firm price.
We repair it
Most lock and alignment work is finished in a single visit.
We are a mobile service covering all three counties. Pick your city below, or call and we will come to you.
Door Lock Repair Across Delaware
Door lock questions
I have to lift the door to lock it.
The slab has dropped on its hinges so the bolt sits below the strike. It is usually loose hinge screws in old jamb wood, and it is a quick repair.
My door locks fine in winter but not in summer.
That is seasonal movement. Delaware's humidity swing is large enough to move a door several millimetres, and the strike can be adjusted to work across both seasons.
Can you rebuild the original mortise lock in my old house?
Often yes. Period lock bodies are usually repairable, and they are generally better made than a modern replacement would be.
Our beach rental has locks that have seized up.
Salt air is almost certainly the cause. We service and replace with corrosion-resistant hardware, and we can do a whole property in one visit between guests.
Do you do rekeying or lockouts?
No — we are a repair and alignment service rather than a locksmith, and we will say so rather than take the job.
Other repairs we handle
Doors and windows are all we do, so whatever has failed, it is probably on this list.
