From glass storefronts to industrial overhead doors — we work on all commercial door types found in Hanover businesses.
The most common type for stairwells and exits in Hanover commercial buildings. Durable and cost-effective. We repair dents, replace hardware, and restore the fire rating on these heavy-duty doors.
Often used in office interiors and hallways where aesthetics matter. Our repair work preserves the wood finish while maintaining the required fire rating. We match existing paint or stain for a seamless look.
Fire-rated glass doors are common in modern Hanover buildings. We replace broken glazing, repair frames, and ensure the entire assembly meets UL listing requirements for fire separations.
Required for high-traffic exits in warehouses and retail spaces. Our team specializes in servicing panic exit devices, push bars, and latches so doors open easily in emergencies but remain secure otherwise.
Preparing Hanover commercial doors for harsh seasonal conditions
Winter freezes cause door frames to contract, leading to gaps that let smoke pass through. Snow and ice can also block door openings. We adjust thresholds and weatherstripping to maintain proper clearance and ensure doors close fully even after extreme cold snaps.
Summer humidity in Hanover swells wood and metal components, often making doors stick or misalign. Our crews perform seasonal tune-ups that include hinge adjustments and closer calibrations. Proactive maintenance prevents emergency calls during peak rental seasons.
Tip: Schedule a pre-winter door inspection in Hanover before temperatures drop — closers and seals need adjustment to perform through subzero conditions.
Don't wait for a door failure to disrupt your business — watch for these common warning signs.
A fire door that stays open or latches improperly is a code violation. This often means the closer or latch needs adjustment. Don't ignore it — call for a quick repair before an inspection.
Bottom and edge clearances must be within NFPA 80 limits. Larger gaps allow fire and smoke to bypass the door. Our team measures and corrects clearance issues with frame adjustments or gasket replacement.
Moisture from rain and snow melt in Hanover can rust hinges, causing doors to sag or bind. Corroded hardware reduces fire rating. We replace affected components with commercial-grade stainless steel parts.
Fire-rated windows in doors must remain intact. Cracks or missing glass compromise the fire separation. We source the correct UL-rated glazing and install it to restore the door's integrity.
Simple Process
3 simple steps from first call to completed work.
We examine every component: hinges, closers, latches, gaskets, and the door itself. This pinpoints exactly what needs repair or replacement.
Our technicians fix or swap out damaged parts using factory-spec materials. No shortcuts — just code-compliant work that lasts.
We test the door's self-closing, latching, and clearance. You get a detailed report for your records and peace of mind.
