After a night of freezing temperatures, a commercial entrance door starts closing more slowly than usual. Employees notice that the latch doesn’t always engage, and water has frozen near the threshold. The door worked normally just a few weeks earlier.
Winter can expose problems with commercial aluminum doors that are less noticeable during warmer months. Cold temperatures, moisture, deicing salts, and repeated use can affect closers, locks, seals, and other components responsible for keeping an entrance operational.
The solution depends on what’s causing the problem. A worn weatherstrip or malfunctioning closer may only need servicing or replacement, while recurring hardware failures and extensive frame damage can make a new entrance system worth considering.
Why Do Commercial Aluminum Doors Have Problems in Cold Weather?
Commercial aluminum doors are built for frequent use, but reliable operation depends on more than the aluminum frame. Closers, hinges, pivots, locks, seals, and thresholds must work together whenever someone enters or leaves the building.
During winter, several conditions can affect these components. Water can freeze inside hardware or around thresholds, while road salt and moisture may accelerate corrosion on exposed metal parts.
Aluminum also contracts slightly as temperatures fall. Properly designed and installed door systems account for thermal movement, so cold weather alone should not cause serious misalignment. However, existing installation problems or worn hardware may become more noticeable as conditions change.
Hydraulic door closers can be particularly sensitive to temperature. Cold conditions may increase the viscosity of the fluid inside certain models, slowing the closing cycle. Closers designed with all-weather hydraulic fluid can provide more consistent performance across seasonal temperature changes.
Understanding which component is affected helps determine whether the entrance needs routine maintenance, professional repair, or a more extensive upgrade.
6 Common Commercial Aluminum Door Problems in Winter
Not all winter door problems appear in the same way. Some affect the door’s movement or locking mechanism, while others involve moisture, corrosion, or gaps around the entrance. Recognizing the specific symptoms can help narrow down the cause and prevent unnecessary repairs.
The following six issues are among the conditions that property managers and maintenance teams should watch for during colder months.
1. Commercial Door Won’t Close or Latch Properly
A storefront door that remains slightly open can become a security concern after business hours. During the day, it may also allow cold air into the building even when no one is passing through.
The way the door behaves provides an important clue. If it moves unusually slowly throughout the closing cycle, the hydraulic closer may be affected by temperature or internal wear. If it reaches the frame but doesn’t latch, the problem could involve the strike, alignment, or interference from a seal or threshold.
Hinges and pivots also influence the position of the door leaf. When these components become worn, the door may begin rubbing against the frame or sitting incorrectly within the opening.
A closer adjustment will not solve every closing problem. The cause should be identified before changing hardware settings, particularly on doors subject to accessibility, fire safety, or emergency egress requirements.
2. Locks, Hinges, and Pivots Become Stiff
A lock that turns normally in October may become difficult to operate after several freezing nights. Moisture inside the mechanism can freeze, while dirt, corrosion, or existing wear may increase resistance.
Similar problems can affect hinges and pivots, especially on entrances exposed to rain, snow, or heavy daily traffic.
Forcing a jammed lock or repeatedly pushing against a sticking door can damage components that might otherwise be repairable. Applying an unsuitable lubricant can also interfere with the mechanism.
When a lock or pivot repeatedly becomes difficult to operate in cold weather, a qualified technician should check its condition and suitability for the installation. Doors used for emergency exits require prompt attention if their operation is impaired.
3. Cold Air Enters Around the Door
A noticeable draft near a closed storefront door often points to gaps around the perimeter, the meeting stiles of double doors, or the threshold.
Weatherstripping is designed to limit air movement through these locations. However, repeated opening and closing can eventually damage seals or cause them to lose proper contact with the door.
Alignment also matters. Even an intact seal may not work as intended if the door leaf no longer sits correctly within the frame.
Inspecting the weatherstripping and checking how the door closes can help identify these issues. Damaged seals may be replaceable without changing the entire entrance.
However, a cold surface is not necessarily evidence of an air leak. Heat transfer through aluminum framing and glazing can create a similar sensation. If the door is properly sealed but the entrance still feels uncomfortable, the building’s thermal performance should be evaluated separately.
4. Ice Builds Up Around Thresholds and Bottom Rails
Ice near a commercial entrance can prevent a door from opening or closing completely. It can also create a slipping hazard for customers and employees.
The problem often begins with water accumulation around the threshold. Melting snow, freezing rain, or moisture carried inside may collect near the entrance, particularly where drainage is obstructed or exterior surfaces direct water toward the opening.
When temperatures fall overnight, that water can freeze along the door’s operating path.
Maintenance teams should remove accumulated snow, keep accessible drainage areas clear, and investigate places where water repeatedly collects.
Avoid forcing a door against frozen deposits or striking aluminum components to break the ice. These actions can damage protective finishes, seals, and hardware.
If ice returns to the same location after every storm, the underlying drainage or installation conditions may need correction rather than repeated cleaning.
5. Deicing Salt Causes Corrosion on Door Components
In regions with heavy snowfall, commercial entrances are regularly exposed to deicing salts used on sidewalks and parking areas.
Salt deposits combined with moisture can accelerate corrosion, particularly around steel fasteners, exposed hardware, and damaged protective finishes.
Aluminum does not develop the same reddish rust associated with iron and steel, but it can still corrode under certain conditions, especially in chloride-rich environments.
The lower sections of an entrance deserve attention because they are exposed to water, cleaning products, and materials carried in from outdoors.
Removing salt deposits with cleaning methods compatible with the existing finish can help limit deterioration. If corrosion affects hinges, pivots, fasteners, or other operational components, a professional inspection is advisable.
During replacement projects, the exposure conditions should also influence the selection of hardware materials, protective finishes, and maintenance requirements.
6. Condensation Appears on Door Glass or Frames
Condensation may form when humid indoor air contacts glass or aluminum surfaces that have become sufficiently cold.
Its presence does not automatically indicate a defective door. Indoor humidity, outdoor temperature, ventilation, and surface temperature all influence condensation.
One distinction is particularly useful: moisture on an accessible glass surface is different from fogging between the panes of an insulated glass unit. Condensation inside the sealed cavity may indicate failure of the unit’s edge seal.
Persistent condensation should be investigated, especially when it affects nearby finishes or is accompanied by other signs of deterioration.
For projects where the concern involves interior surface temperatures and heat transfer rather than mechanical operation, our guide to glass and aluminum systems for buildings in very cold climates explains the relevant glazing and framing considerations.
Winter Door Troubleshooting: What Should You Check First?
Several winter door problems produce similar symptoms. Before requesting service, observe when the issue occurs and which part of the entrance appears to be affected.
Symptom | Possible cause | Recommended next step |
Door closes unusually slowly | Hydraulic closer affected by temperature or wear | Request a closer inspection |
Door reaches the frame but won’t latch | Strike misalignment, worn hardware, or obstruction | Check for visible obstructions and have the alignment evaluated |
Lock becomes difficult to turn | Frozen moisture, corrosion, or internal wear | Have the lock mechanism inspected |
Draft is noticeable around a closed door | Worn weatherstripping or gaps around the assembly | Inspect seals and door alignment |
Ice repeatedly forms at the threshold | Water accumulation or inadequate drainage | Investigate drainage and threshold conditions |
Lower hardware shows corrosion | Salt exposure, moisture, or damaged finishes | Assess deterioration and replace affected parts when necessary |
These observations can help a facility manager explain the problem to a technician. They should not be treated as a complete diagnosis, and adjustments involving closing force, latching, or required exits should be performed by qualified personnel.
How to Prevent Commercial Door Problems Before Winter
Preparing an entrance before the first freezing temperatures can reduce unexpected interruptions, particularly in busy retail, office, and institutional buildings.
A preventive inspection should address five areas:
- Door operation: Confirm that each leaf opens freely, closes consistently, and latches without additional force. Unusual noise, rubbing, or inconsistent movement may indicate an existing hardware problem.
- Weatherstripping: Examine the perimeter and bottom seals for tears, displacement, or poor contact. Check the meeting stiles of double doors as well.
- Thresholds and drainage: Remove debris and identify locations where rainwater or snowmelt accumulates. Keep designated drainage openings unobstructed.
- Hinges, pivots, and locks: Look for loose components, visible corrosion, or resistance during normal operation. Follow the hardware manufacturer’s maintenance instructions.
- Glazing and frame condition: Check for cracked glass, loose glazing components, damaged gaskets, and deterioration around the frame connections.
Inspection frequency should reflect the entrance’s traffic volume, exposure to severe weather, and the manufacturer’s recommendations.
A storefront door used hundreds of times each day may require closer attention than an entrance serving a low-traffic office. Buildings with automatic entrance systems should also follow the operator manufacturer’s inspection and servicing requirements.
It is worth keeping records of recurring problems. If the same door requires repeated closer adjustments or regularly fails to latch in winter, that history can help determine whether continued maintenance remains practical.
When Should You Repair or Replace a Commercial Aluminum Door?
Not every winter problem requires replacing the complete entrance.
A worn hinge, damaged weatherstrip, or malfunctioning closer may be repaired or replaced individually when the surrounding door and frame remain in good condition.
Professional repair is generally worth considering when the problem is limited to a serviceable component, compatible parts are available, and the entrance continues to meet the building’s operational requirements.
Replacement becomes a stronger option when the problems affect the system as a whole.
For example, a commercial entrance may have recurring alignment issues, extensive frame damage, deteriorated glazing components, and multiple hardware failures. Replacing a single component may restore operation temporarily without addressing the broader condition of the assembly.
Consider a busy retail entrance that has required several hardware repairs over successive winters. The door still sticks against the frame, and the latch no longer engages consistently. If inspection reveals significant frame deterioration or other problems that cannot be corrected reliably through component replacement, a new entrance may be the more practical long-term option.
The decision should take into account the condition of the door and frame, availability of compatible parts, maintenance history, expected traffic, and the cost of repair compared with replacement.
For planned renovations, the evaluation may also include updated requirements for accessibility, security, glazing, and entrance operation.
What to Look for in a Replacement Commercial Aluminum Door
Replacing an entrance creates an opportunity to review the door configuration and its components together rather than selecting another door based only on the existing opening dimensions.
For contractors and architects, several details influence how reliably the new system will operate during winter and throughout the year.
Door configuration and expected traffic
Start with the opening dimensions, single- or double-door arrangement, swing direction, and frequency of use.
A heavily used storefront entrance may require different hardware than a secondary door opened only occasionally. The selected configuration should also accommodate the building’s required clear opening and accessibility provisions.
Hardware compatibility
Closers, pivots, hinges, locks, and panic devices must be appropriate for the door’s dimensions, weight, operation, and applicable code requirements.
Consider the expected opening cycles and environmental exposure when choosing these components. For exterior installations in cold regions, the hardware manufacturer’s specified operating temperature range may also be relevant.
Thresholds, seals, and drainage
The door’s sealing arrangement needs to work with the frame, threshold, and surrounding construction.
A properly selected entrance can still experience problems if water accumulates at its base or if the door leaf does not make consistent contact with the seals.
Drainage paths, weatherstripping compatibility, and installation details should therefore be reviewed before fabrication and installation.
Coordinated framing, glazing, and hardware
PRL Glass & Aluminum manufactures aluminum entrance doors in narrow-, medium-, wide-, and custom-stile configurations for commercial applications.
Available options include different glazing arrangements, door rails, pivots, hinges, handles, and panic hardware, subject to the selected system’s specifications.
For projects involving a larger entrance renovation, PRL also manufactures commercial aluminum storefront systems that can be coordinated with compatible doors, glass, and hardware.
These systems are available in different framing configurations, including selected thermal and non-thermal options. The appropriate assembly depends on the building’s requirements, and thermal performance should not be assumed to be identical across all aluminum door products.
PRL’s in-house fabrication capabilities allow contractors and architects to review coordinated entrance components rather than treating the door leaf, surrounding frame, and glazing as unrelated selections.
Before ordering, confirm the opening dimensions, intended use, glazing requirements, hardware configuration, and any additional project performance criteria.
