Andover, Minnesota winters put extra stress on door hardware — expansion and contraction can misalign latch holes and short wiring connections. We’ve installed hundreds of 12v electric strikes across Anoka County and know exactly how to seal and protect connections against moisture and salt corrosion.
Our crew lives and works in the North Metro. When an Andover property manager calls us, we’re on-site within an hour, not driving from the other side of the Cities. That local speed and accountability is why building owners stay with us year after year.
Serving Andover and surrounding communities — local crews, fast scheduling, no call centers.
From glass storefronts to industrial overhead doors — we work on all commercial door types found in Andover businesses.
Common in retail and office storefronts. We install 12v electric strikes that fit narrow stile frames and integrate with existing panic hardware or pull handles.
Standard in warehouses, schools, and apartment buildings. Electric strikes mount flush in the frame, and we reinforce the jamb if needed to prevent kick-in damage.
Found in older Andover commercial buildings and interior offices. We carefully route wiring inside the frame and use strike models that match the wood finish without visible screws.
Required in stairwells and egress corridors. We install UL-listed electric strikes that maintain the door’s fire rating and pass local inspection in Andover.
Preparing Andover commercial doors for harsh seasonal conditions
Andover temperatures drop below zero for weeks at a time, and freeze-thaw cycles can cause door frames to shift. A badly installed 12v electric strike may fail to latch in cold weather. We use thermal-rated wire, weatherproof connections, and leave enough slack in the conduit to accommodate frame movement.
Summer humidity also affects electric strikes — moisture buildup inside the strike can cause intermittent locking. Our installations include drain weepholes and dielectric grease on terminals. We also offer seasonal maintenance checks so your access control works reliably March through February.
Tip: Schedule a pre-winter door inspection in Andover 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 the electric strike fails to hold the latch, the solenoid or power supply may be failing. In Andover buildings, this is often caused by voltage drop in long wire runs. Call us to test and replace before a security breach.
A buzzing sound without release usually means the strike’s coil is burned out or the latch is misaligned. This is common after power surges in Minnesota storms. We carry replacement coils for same-day fix.
Loose connections or corroded terminals cause random failures. In older Andover buildings, we often find oxidized wires in the door frame. A full re-termination solves it fast.
A visible bent strike face or broken tab means the door was forced or a crash bar hit it. This compromises security. We remove the damaged unit and install a new, reinforced 12v electric strike.
Simple Process
3 simple steps from first call to completed work.
We inspect your existing door frame, wiring, and access control system. This tells us exactly which 12v electric strike model fits your Andover building and voltage requirements.
Our technicians cut, mount, and wire the new electric strike to match your door prep and power supply. Every connection is tested for fail-safe or fail-secure operation.
We test the strike with your card reader, keypad, or remote release. Then we show you how to adjust the latch position and troubleshoot common issues — so you’re never locked out.
