Fire-rated glass doors with wire or ceramic glazing. Common in lobby entrances and exit corridors where visibility is needed while maintaining a fire barrier.
Preparing Cottage Grove commercial doors for harsh seasonal conditions
Minnesota winters bring extreme cold and snow buildup. Fire door frames can contract, causing gaps or binding. Snow piled against exterior fire doors can block egress. We winterize your doors by adjusting closers, lubricating hardware, and clearing pathways.
Summer humidity and heat can warp door slabs or cause sticking. Heavy rain can also damage thresholds and seals. We recommend seasonal inspections to catch small problems before they become emergency repairs. Our Cottage Grove crews adjust doors for seasonal changes year-round.
Tip:Schedule a pre-winter door inspection in Cottage Grove 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 must close and latch automatically. If it sticks or stays open, your building may not be in compliance. Call us for adjustment or closer replacement.
NFPA 80 specifies maximum gaps between door and frame. Excessive gaps allow smoke and fire to pass through. We can install intumescent seals or adjust hinges.
Cracked glass in fire doors compromises the rating. Replacement must use approved fire-rated glass and be installed by a certified contractor. We stock common sizes.
Missing closer arms, broken locks, or damaged panic hardware make fire doors non-functional. We repair or replace hardware to restore proper operation and code compliance.
