Key facts in 20 seconds
- Most Richfield garages open onto an alley, and the City plows alleys last, after arterials, collectors and residential streets. A snow emergency is automatic after 4 inches. Source: richfieldmn.gov/snow.
- The four winter problems I see on alley garages, in order: the plow windrow against the door, the bottom seal frozen to the slab, salt rust on the bottom section and brackets, and a door or track clipped by a car or the plow in a tight alley.
- What they cost to fix (from my cost calculator, exact quote on site): off-track or bent track from $450 including cables, bent bottom section $200 to $600 per section, new insulated steel door from $2,000, winter tune-up $129 with code WINTER through Dec 15, 2026.
- Never use the opener to break the door loose from ice. Shovel, free the seal, lift by hand, then run it. (763) 265-7671, same day, St. Louis Park to Richfield in about 15 minutes.
Richfield was platted with alleys, and that is where most of its garages live: a single-stall or two-car garage at the back of a 40- or 50-foot lot, door facing a 16-foot alley, with the neighbor’s garage eight feet across from it. In summer that is a nice, quiet arrangement. From December to March it is the hardest place in the Twin Cities to own a garage door, because everything the alley does in winter ends up at the bottom of your door. This guide is the alley-specific companion to my Richfield single-stall garage guide and the garage rebuild checklist.
How the City plows, and why the alley comes last
The City of Richfield’s snow page sets the order: high-volume arterials and the sidewalks along them first, then neighborhood collector streets, then local residential streets, and alleys fourth. Hennepin County handles 66th, Penn, Nicollet and Portland. A snow emergency is automatically in effect after 4 inches, street parking is banned until the street is plowed curb to curb, and there are 392 snow-emergency spaces on Cedar Avenue for people without off-street parking. None of that is a complaint about Public Works; a small city clearing every alley after a 10-inch storm is a lot of work. It just means two things for your door: the alley gets plowed after you have already driven in and out a few times and packed the snow, and when the plow does come, it leaves a windrow exactly where your door meets the slab. (Check richfieldmn.gov/snow for the current rules; the snow hotline is 612-861-9178.)
Photos from my own jobs around the Twin Cities.
Problem 1: the windrow against the door
The plow blade angles the snow to the side, and on a 16-foot alley the side is your door. A foot of packed, salty snow against the bottom section does three things: it stops the door from opening, it pushes the bottom section inward against the vertical track so the rollers bind, and when it melts in the afternoon and refreezes at night it glues the bottom seal to the slab. The fix is a shovel before the opener, every time. If you come home to a windrow and the door is already up, clear the full width before you close it, because closing a door onto a ridge of frozen snow is how bottom sections crack and how a cable jumps the drum. If the door is down and won’t lift, go to Problem 2.
Problem 2: the seal frozen to the slab
This is the most common winter call I get from Richfield, and the one most often made worse by the homeowner. The rubber bottom seal sits in the meltwater, the temperature drops, and the seal is now part of the slab. The opener pulls, the door does not move, and one of three things gives: the opener’s drive gear strips, the top section bends where the opener arm attaches, or the bottom seal tears off the door. All three cost more than a frozen seal. Release the opener (pull the red cord), break the seal loose by hand with a gentle rock side to side, and only then reconnect and run it. If it will not break loose, warm water along the seal, not hot, and a plastic scraper. Silicone spray on a clean, dry seal in November keeps it from happening in the first place; that is part of my winter tune-up. The full step-by-step, including the cases where it is not the seal, is in why a garage door won’t open in the cold.
Problem 3: salt rust on the bottom of the door
Alleys get salted, and the alley is almost always higher than the garage slab, so the brine runs under the door and sits. The bottom section, the two bottom brackets that hold the cables, and the lowest hinges rust first. Rusted bottom brackets are the dangerous one, because that is where the lift cable is anchored and the spring tension lives; when a rusted bracket lets go the door drops on one side. Signs you can check from the alley: orange streaks down the bottom panel, a bottom seal that has gone flat or crumbled, hinges with rust blooming out of the rivets. A 1950s wood or early steel door with a rusted-through bottom section is a replacement conversation, not a repair; a newer steel door with surface rust is a bottom-seal and brackets job. The Age Check tool tells you which conversation you are having, and panel replacement covers the middle case.
Problem 4: the door or track clipped in the alley
A 16-foot alley with a garage on each side leaves no room to swing wide, and a bumper or a mirror catches the edge of the door or the vertical track more often than people admit. A plow blade does the same to the bottom corner. A bent vertical track or a roller knocked out is an off-track repair, from $450 including new cables, and it should be done the same day, because a door hanging on one cable is the one case I tell people not to touch at all. A dented bottom section is $200 to $600 to replace, if the panel is still made for your door; on a door older than about 2005 it often is not, and that is when a new insulated door from $2,000 installed makes more sense than chasing one section. Details in off-track repair and a door that hangs crooked.
What to do in November, not January
Everything above is cheaper before the first 4-inch storm. A winter tune-up on an alley garage means: lubricate and check the spring and the hinges, clean and silicone the bottom seal so it cannot freeze down, check the bottom brackets and cables for rust, set the opener’s force so it reverses on a frozen seal instead of tearing the door, and look at the weatherstrip along the jambs where the drifts pile. It is $129 with code WINTER through December 15, 2026, and it is the single best money a Richfield alley garage can spend. Book on the Richfield page or call (763) 265-7671; I am in St. Louis Park, about 15 minutes up Highway 100.

Richfield alley garage questions
Does the City of Richfield plow the alleys?
Yes. The City’s snow page lists alleys as the last of four plowing priorities, after arterial streets and sidewalks, collector streets and local residential streets, so an alley garage can sit behind an unplowed alley for a while after a big storm. A snow emergency is automatically in effect after 4 inches of snow and street parking is prohibited until the street is plowed curb to curb. Check richfieldmn.gov/snow or the snow hotline at 612-861-9178 for the current rules.
The plow pushed snow against my garage door and now it won’t open. What do I do?
Do not run the opener against it. Shovel the windrow away from the door, clear the bottom seal and the two bottom corners, and try again by hand with the opener released. If the door still won’t lift, the bottom seal has usually frozen to the slab or the ice has lifted the door off a roller; both are quick fixes but forcing the opener strips the gear or bends the top section. My guide to a garage door that won’t open in the cold covers the frozen-seal case step by step.
How much does it cost to fix a garage door hit by a plow or a car in the alley?
It depends on what bent. Straightening or replacing a bent vertical track and resetting the rollers is part of an off-track repair, from $450 including new cables. A dented or cracked bottom section is a panel replacement, $200 to $600 per section depending on the door. If two or more sections are bent on a 1950s door, a new insulated steel door from $2,000 installed is usually the better money. All current prices are on my cost calculator; I quote the exact number on site before any work.
Why does the bottom of my alley garage door rust out first?
Richfield alleys are plowed and salted, and the meltwater runs toward the garage because the alley is usually higher than the slab. The bottom section, the bottom brackets and the lowest hinges sit in salty slush from February to April. Galvanized bottom brackets, a vinyl-backed bottom section that does not absorb water, and a fresh bottom seal every few years are what slow it down.
Will a new garage door opener help with a frozen door?
A good opener helps a little and a bad habit hurts a lot. A LiftMaster belt opener with a proper force setting will stop and reverse on a frozen seal instead of tearing the bottom section, and the myQ app tells you the door is still closed before you leave the house. But no opener should be used to break a door loose from ice. New LiftMaster myQ opener installed is $650 to $1,500; opener repair $75 to $200.
In the city itself, the garages are on the alley: Minneapolis alley garage doors, single-stall, tandem and rebuilt.
