EXCELLENT
Real feedback from businesses we’ve helped with commercial door installation, repair, automatic systems, and security upgrades.
Whether it’s a Norton, LCN, or Dorma closer, we repair or replace it correctly the first time. No guesswork.
Every repair comes with a workmanship guarantee. If it fails, we come back — no extra charges.
Found on warehouses, back entrances, and schools. Heavy doors require heavy-duty closers. We install LCN 4040 or 1461 models for reliable performance in high-traffic areas.
Required for stairwells and corridors in commercial buildings. Closers on fire doors must be listed and properly mounted. We source approved models that meet Delano fire marshal requirements.
Used in banks, lobbies, and restaurants. These doors need concealed or surface-mounted closers that don’t detract from aesthetics. We handle Dorma and Rixson units.
Preparing Delano commercial doors for harsh seasonal conditions
Minnesota winters are brutal on door closers. Freezing temperatures cause hydraulic oil to thicken, slowing door operation. Snow and ice buildup near the threshold can also affect closing force. We recommend annual fall tune-ups to adjust spring tension before the first hard freeze.
Summer heat and humidity can cause closers to overheat or leak oil. In Delano, spring and fall are the busiest times for repairs. Our technicians check for loose screws, worn seals, and alignment issues during seasonal weather swings to prevent sudden failures.
Tip: Schedule a pre-winter door inspection in Delano 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.
If your door closes too hard or slams, the closer’s backcheck or sweep speed is off. This can damage the frame and create safety hazards.
A door that stops an inch or two from the latch is a sign of low hydraulic fluid or a bent arm. It compromises security and energy efficiency.
Puddles or streaks under the closer mean internal seals are failing. The closer will stop working soon — call for a replacement.
If the door flies open when pushed, the backcheck adjustment is set too light. This is dangerous in crowded hallways and needs immediate repair.
