From glass storefronts to industrial overhead doors — we work on all commercial door types found in Mendota Heights businesses.
Standard 16-gauge or 18-gauge steel doors rated for 90-minute fire protection. Ideal for stairwells, mechanical rooms, and rear exits in Mendota Heights commercial buildings.
Lightweight but strong, these doors provide fire resistance with a clean, modern look. Common in office lobbies and storefronts where aesthetics matter.
Preparing Mendota Heights commercial doors for harsh seasonal conditions
Minnesota winters can wreak havoc on fire doors. Freeze-thaw cycles cause frames to shift, hinges to bind, and seals to crack. We use heavy-duty weatherstripping and self-closing hardware rated for temperatures down to -30°F. Regular winter inspections prevent doors from sticking or failing to latch properly.
Summer humidity can also swell wood and hollow metal doors, leading to clearance issues that violate fire codes. Our crews adjust gaps and lubricate hardware seasonally. If your door has been acting up after a temperature swing, call us — we can tune it up in one visit and keep your building compliant year-round.
Tip:Schedule a pre-winter door inspection in Mendota Heights 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 doesn't close and latch automatically is a code violation. This is the most common issue we see in Mendota Heights buildings. Warped frames, loose hinges, or broken closers are usually the cause.
Fire doors must have tight clearances. If you can slide a nickel through the gap, it's too large. Gaps allow smoke and flame to spread during a fire.
Every fire door must have a visible UL or Warnock Hersey label. If the label is painted over, missing, or damaged, you need a replacement or recertification before your next inspection.
Settling foundations, snow buildup, or seasonal expansion can cause doors to scrape. This wears out hardware and prevents proper latching. Quick adjustments keep your door compliant.
