Door Adjustment & Alignment Service on Long Island
A door that sticks in summer, drags along the floor, or lets cold air through the seal is one of those problems that homeowners in Long Island tend to live with far longer than they should. It feels minor until it's January and your front door needs a shoulder charge to close, or you notice your heating bill has quietly climbed because the weatherstrip seal failed months ago.
At Prestige Window Works, we provide professional door adjustment and exterior door repair throughout Long Island, NY, serving homeowners across Nassau County and Suffolk County. Our technicians diagnose why your door has stopped operating correctly and fix the root cause, not just the visible symptom, so the problem doesn't return with the next change of season.
Most door adjustments are completed in a single visit with no parts needed. Every job comes with a warranty on workmanship. Entry doors, French doors, sliding patio doors, storm doors, interior and exterior — every door type adjusted using the correct method for that specific frame and hardware system. We don't leave until the seal is verified, not just assumed.
Door Problems We Fix
Doors operate correctly within a narrow tolerance: the gap between door and frame, the hinge position, the strike plate alignment, and the weatherstrip compression all need to be within a few millimetres of their intended positions. Long Island's climate pushes every one of those tolerances constantly.
Doors That Stick or Are Hard to Open
Sticking is the most common door complaint we receive from homeowners across Long Island. We identify whether the cause is wood swelling, a shifted frame, a dropped hinge, or a combination, and address each cause specifically. For wood doors, we plane only the minimum material needed and seal the exposed grain immediately to prevent moisture re-entry. For doors that have shifted in their frame, we re-hang or shim as needed.
Doors That Won't Latch Without Force
If your door closes but the latch won't engage the strike plate without lifting the handle or giving the door a firm push, the door has dropped at the hinge side. The latch bolt is no longer aligned with the strike plate mortise. We tighten and reinforce the hinge screws or replace the hinges entirely if they've worn, and reposition the strike plate to match the new latch position. This is one of the most common exterior door problems in Merrick, Bellmore, and Wantagh.
Doors That Drag on the Floor or Threshold
A door that scrapes along the floor has either dropped at the hinges or the floor level has risen (from a new floor covering being installed over the original). We raise the door back to correct height by tightening hinges, adjusting the hinge mortise depth, or trimming the bottom edge if the floor height has genuinely changed. We also inspect the threshold seal condition and replace it if needed.
Drafty Exterior Doors
Cold air coming through a closed exterior door costs real money every Long Island winter. The most common causes are: compressed or missing weatherstrip around the door perimeter, a threshold seal that no longer contacts the door bottom, or a door that sits slightly out of plumb and creates an uneven gap on one side. We address all three in a single visit, replacing weatherstrip, adjusting or replacing the threshold seal, and correcting the door hang if needed.
Doors That Swing Open or Closed on Their Own
A door that won't stay where you put it, swinging closed under its own weight or slowly drifting open, is out of plumb. The hinge side of the frame is not perfectly vertical, so gravity pulls the door toward whichever direction is lower. We correct the hinge positions to bring the door back to plumb so it stays wherever you leave it.
French Doors That Don't Align
French doors present a specific alignment challenge because both panels need to meet precisely at the center, and both are subject to the same seasonal movement and hinge wear as any other door. When French doors stop meeting flush, the astragal seal fails and the locking bolts no longer engage the floor and header keeps correctly. We adjust both panels independently to restore flush alignment and correct lock engagement.
Storm Door Alignment and Adjustment
Storm doors develop their own set of alignment issues. Doors that don't close fully on the pneumatic closer, that gap at the latch side, or whose frame has shifted relative to the entry door behind it.
We adjust storm door hinges, closer tension, and latch alignment as a standalone service. See also our storm door installation and adjustment service for more detail.

How Our Door Adjustment Process Works
Step 1 — Diagnose the full door system
We test the door through its complete range of operation: open, close, latch, lock, and check the seal perimeter with a draft detector. We look at the hinge condition, frame squareness, threshold seal, weatherstrip, and lock alignment before recommending any work. You get a written quote before we touch anything.
Step 2 — Identify root cause, not just symptoms
A door that won't latch has a dropped hinge, not a misaligned strike plate. A door that sticks in one corner has a racked frame, not just swollen wood. We trace every problem to its source so the fix addresses the cause, not just the effect.
Step 3 — Adjust, rehang, or plane
We perform the specific work the door needs: tightening or replacing hinges, planing wood, shimming the frame, repositioning the strike plate, replacing weatherstrip, or adjusting the threshold. Most door adjustments require no replacement parts.
Step 4 — Test and verify the seal
After adjustment we close and latch the door, check the gap uniformity around the full perimeter, and test the draft seal at the threshold and all four sides. A correctly adjusted door should close cleanly, latch without force, lock smoothly, and show no light gap around the perimeter.
Step 5 — Seal exposed wood and clean up
Any bare wood exposed by planing is primed and sealed before we leave. We clean up all shavings and debris. You test the door yourself before we pack up.

THE MOST POPULAR QUESTIONS
My front door sticks every summer but is fine in winter. Is that normal?
Very common in Long Island, and completely fixable. Wood doors and frames absorb moisture during humid summers and swell enough to bind in the frame. The correct fix is planing the binding edge to restore the proper clearance, then sealing the bare wood so it resists moisture re-entry. We size the gap to work correctly in summer because the slight looseness you might feel in winter is normal and much less of a problem than a door that won't close in August.
My door closes but the latch won't catch unless I lift the handle, what's wrong?
The door has dropped at the hinge side, which is extremely common in Long Island homes with solid wood entry doors. The latch bolt is now lower than the strike plate mortise. We tighten and reinforce the hinge screws, sometimes using longer screws that reach the structural framing behind the jamb, and reposition the strike plate to align with the new latch position.
How much does door adjustment cost in Long Island?
Most door adjustments cost is determined by what's needed. Simple hinge tightening and strike plate adjustment is at the lower end. More involved work like planing a solid wood door, rehanging on new hinges, and replacing the full weatherstrip system is at the higher end. We provide a written quote on-site before any work starts.
Can you adjust sliding patio doors as well as hinged doors?
Yes. Sliding patio door adjustment covers track cleaning and straightening, roller height adjustment, and end-stop positioning. If the rollers themselves are worn out and need replacement, that falls under our window and door mechanism repair service.
My door was recently replaced but already sticks. Is that a warranty issue?
It may be, depending on who installed it. But more often, a newly installed door that sticks is simply a result of the door not being hung plumb and square is a common installation quality issue. We can adjust it correctly regardless of who installed it. If it's within a contractor's warranty period, document the issue before calling them.
Do you repair door frames as well as the door itself?
Yes. If the frame has shifted, cracked, or rotted, we address it as part of the adjustment work. For significant wood rot in door frames specifically, see our rotten window repair service, the same repair methods apply to door frames.
