What We Repair
Door & Lock Repairs — Interior, Exterior, and Everything Between
Every door problem has a specific cause and a specific fix. NorTech technicians diagnose on-site and repair correctly — not just force the door closed and move on.
Sticking & Binding Doors
Doors that drag, catch, or require force to open diagnosed for root cause — hinge sag, frame settling, seasonal expansion, or paint buildup — and corrected accordingly.
Hinge Repair & Replacement
Loose, squeaky, bent, or broken hinges tightened, repaired, or replaced. Stripped hinge screw holes reinforced with solid wood filler before remounting.
Strike Plate Adjustment
Misaligned strike plates — the most common cause of doors that won’t latch — repositioned so the latch bolt seats correctly every time.
Lockset Repair & Replacement
Loose, stiff, or malfunctioning door knobs, lever handles, and passage locksets repaired or replaced — interior and exterior doors serviced.
Deadbolt Installation & Repair
New deadbolt installation on existing doors, and repair of deadbolts that stick, misalign, or no longer throw fully — single and double cylinder configurations.
Door Closer & Sweep Adjustment
Door closer speed and tension adjusted so doors close fully without slamming. Door sweep replacement on exterior doors that no longer seal at the threshold.
Common Problems
Door Problems and What’s Actually Causing Them
Most door problems have a clear cause. Here’s what your technician will look for — and fix — on arrival.
Door Won’t Latch
Usually a misaligned strike plate. The latch bolt hits the plate face instead of seating in the hole — a 10-minute fix once diagnosed correctly.
Door Sticks at Top or Side
Typically hinge sag pulling the door down, or seasonal wood expansion. Hinge tightening or door edge planing resolves most cases without replacing the door.
Door Swings Open on Its Own
An out-of-plumb door frame or a hinge with bent leaves causes the door to swing. Hinge leaf straightening or frame shimming corrects the behavior.
Squeaky Hinges
Dry hinge pins or worn hinge knuckles. Lubrication solves most squeaks — worn hinges are replaced if lubrication doesn’t hold.
Deadbolt Won’t Throw Fully
Misalignment between the bolt and the strike box. Strike plate adjustment or lockset replacement depending on how far off the alignment is.
Loose Door Knob or Handle
A loose set screw or worn spindle connection. Tightened or replaced — most loose handles are a 5-minute fix once the door is open on a workbench.
Pricing
What Door & Lock Repair Costs
Pricing depends on the type of repair, whether hardware replacement is needed, and the number of doors. A strike plate adjustment is a quick fix — a full deadbolt replacement with frame reinforcement is a different scope.

Customer Reviews
What Customers Say About NorTech Door & Lock Repair
“Front door had been sticking for two years — had to shoulder it open every time. Tech diagnosed it as hinge sag in about two minutes, tightened and repositioned the hinges, and the door swings perfectly now. Wish I’d called sooner.”
Robert L.
“Bedroom door wouldn’t latch — had to push it firmly every time. Tech adjusted the strike plate in about 10 minutes. Latches perfectly now. Simple fix but one I wouldn’t have known how to do myself.”
Carla M.
“Had a deadbolt that wouldn’t throw all the way. Tech diagnosed a strike alignment issue, adjusted the plate, and it works perfectly. Also tightened two loose door knobs while he was there. Good efficient visit.”
Vincent T.
“Three interior doors all had the same problem — swinging open on their own. Tech adjusted the hinges on all three and explained what was causing it. All three stay put now. Quick, clean, professional.”
Theresa K.
“Door repair was done well — latches correctly now. Tech was a bit quiet about what he was doing so I wasn’t sure what the problem was until he explained at the end. Result is good, just would’ve appreciated more communication.”
Norman B.
“New deadbolt installed on the back door — old one was worn and the key stuck half the time. Tech replaced it cleanly, tested the throw several times, and the new one works flawlessly. Good hardware recommendation too.”
Pamela G.
FAQ
Door & Lock Hardware Repair — Frequently Asked Questions
Specific questions about NorTech’s door and lock repair service, scope, and what to expect.
What door and lock repairs does NorTech provide?
NorTech repairs sticking and misaligned doors, worn or broken hinges, misaligned strike plates, loose or malfunctioning locksets, deadbolt installation and repair, door closer adjustment, and door frame damage affecting operation. Both interior and exterior doors are serviced.
How much does door repair cost?
Door repair cost depends on the type of problem, whether hardware replacement is needed, and your location. NorTech provides a free upfront estimate before any work begins.
Why is my door sticking and how do you fix it?
Doors stick for several reasons — seasonal wood expansion, hinge sag, settling of the door frame, or paint buildup on the edge. Your technician will diagnose the cause on arrival. Fixes range from hinge adjustment and tightening to planing or sanding the door edge, depending on the root cause.
Can NorTech repair a door that won’t latch or lock?
Yes. A door that won’t latch or lock is typically a strike plate alignment issue or a sagging hinge problem. Your technician will adjust the strike plate, correct the hinge position, or replace the lockset if the mechanism itself has failed.
Can NorTech install a new deadbolt?
Yes. Deadbolt installation on existing doors is a standard service — including single-cylinder and double-cylinder deadbolts. If a new hole needs to be drilled, your technician will advise on door thickness compatibility before proceeding.
Does NorTech repair both interior and exterior doors?
Yes. Interior doors, exterior entry doors, sliding doors, French doors, and pocket doors are all serviced. Exterior door repairs include weather seal and threshold assessment as part of the diagnosis.
What if the door frame itself is damaged?
Minor door frame damage — stripped hinge screws, small splits, and worn strike plate areas — is repaired as part of this service. Major frame replacement or structural door frame work is outside the scope of this service; your technician will advise if that’s the case.
Is door and lock repair covered by a warranty?
Yes. All NorTech door and lock hardware repair work is backed by a 1-year labor warranty. If any workmanship issue arises within 12 months, we return and correct it at no additional labor cost.
