Home / Door Closer
Keep entrances safe, smooth and code-ready. IN-N-OUT Locksmith installs, services and tunes surface, concealed and floor-spring door closers for commercial buildings across Baltimore, Howard, Anne Arundel, Harford and Carroll Counties. We restore controlled closing, reliable latching and comfortable opening force on aluminum storefront, wood and hollow-metal doors.
Surface closers (regular, top-jamb and parallel-arm mounts)
Concealed closers (in-door or in-frame units)
Floor-spring closers for glass/frameless and heavy doors
Hold-open arms (where permitted; not for fire-rated openings)
Backcheck, sweep, latch & delayed-action valve tuning
Closer shoes, covers, brackets and through-bolt reinforcement

Door slams or won’t latch: valve drift, wrong spring size, worn hinges or misaligned strike
Door won’t stay closed: insufficient latch speed, stack pressure at vestibules, failed latch bolt
Opening is too heavy: arm type or spring size mismatch; ADA force not met
Oil leaks / failed closer body: replacement with through-bolting to prevent future pull-out
Wind load at storefronts: backcheck tuning and arm upgrades for controlled swing
Our survey checks door alignment, hinges, weatherstrip, threshold and strike. Restoring closer performance often requires minor hinge/strike work in addition to valve tuning.
New closer installation on aluminum storefront, wood and hollow-metal doors
Like-for-like replacement of worn or discontinued models
Valve tuning (backcheck, sweep, latch, delayed action) for smooth, safe operation
ADA opening-force adjustment and handle/clearance review
Arm upgrades (parallel, heavy-duty, hold-open where allowed)
Reinforcement & through-bolting to stop screws pulling out of thin storefronts
Hinge, strike & latch work to ensure positive latching without slamming
Fire-rated opening service using listed/labeled components as required by your authority having jurisdiction
Every job ends with a functional test: opening force, controlled swing, latch engagement and clear egress.
Most commercial doors must open with reasonable force and close in a controlled way so people can exit easily. Requirements vary by building type and local authority. Our installs follow widely accepted guidelines for single-motion egress, positive latching, appropriate opening force and clearances. For fire-rated doors, we use listed, labeled hardware and avoid hold-open arms unless released by an approved system.

Pricing depends on door type (storefront vs. hollow-metal), closer style (surface, concealed, floor-spring), size, finish and whether the opening is fire-rated. You’ll receive a written, itemised quote before work begins. Phones are answered daily from morning through midnight, and installation windows are planned around your operations.
Yes. We size the closer and tune valves/arms to achieve a comfortable opening force while preserving reliable latching.
They can be acceptable on non-rated doors. Fire-rated doors generally require self-closing without mechanical hold-open unless released by an approved system.
Slamming often indicates other issues such as hinge wear, misaligned strikes or stack pressure. We address the full opening, not just the valves.
Yes. We install and tune closers for narrow-stile aluminum doors and reinforce thin sections with through-bolts where needed.
Phones are answered 8 AM to 12 AM daily. We schedule daytime and evening windows to fit your business hours.
