Garage Door Weather Sealing in Minneapolis
A single-car alley garage built before 1940 in Minneapolis frequently still has its first weatherstripping, and rubber that old has usually gone stiff enough to crack rather than flex against the door.

Weather Sealing for Minneapolis homes
Because these garages sit at the back of the lot with the door facing an open alley rather than a sheltered driveway, they also take a more direct hit from wind-driven snow than a front-facing suburban garage would.
- A cracked or missing bottom seal on an alley garage lets drifting snow blow straight in overnight, not just settle at the threshold.
- An unheated alley garage gains the most from a full weatherstrip replacement, since there's no furnace output to make up for what a bad seal lets escape.
Know the signs
When you need weather sealing
Common symptoms
- Visible daylight along the bottom, sides, or top of a closed door
- Drafts, dust, leaves, or small pests getting into the garage
- Water coming in along the bottom during rain
- Weatherstripping that's cracked, flattened, torn, or missing sections
What the service covers
- Inspection of the bottom seal, side and top weatherstripping, and threshold
- Replacement of the bottom seal, sized to the door's track
- Replacement of side and top weatherstripping along the jambs and header
- Check for gaps at the corners and threshold where seals meet
The process
How the work is done
- 1
Inspect all seal points
The bottom seal, side and top weatherstripping, and the threshold area are checked for cracking, flattening, gaps, or missing sections.
- 2
Remove worn seals
Old, hardened, or torn weatherstripping is pulled from its retainer track or fastening strip.
- 3
Fit new seals
New bottom seal, side, and top weatherstripping sized to the door and opening are fitted into place.
- 4
Check the seal along a full cycle
The door is closed and checked along its full length for daylight gaps or spots where the new seal isn't making even contact.
Cost factors
What affects the price
Prices aren't published because they depend on your door, the parts involved and the access to the work. These are the things that move the cost — ask for the price before any work starts.
- Which seals need replacing
- A worn bottom seal alone is less involved than replacing seals on all four sides.
- Door width
- Wider double doors need more material for bottom and top seals than single doors.
- Threshold and floor condition
- An uneven or damaged concrete threshold can make it harder for even a new seal to sit flush.
- Seal type
- Different bottom seal profiles fit different track retainers on the door's bottom section.
Safety first
- Keep hands clear of the door's edges and any pinch points while old weatherstripping is being removed and new material fitted.
- Do not attempt to adjust the door's tracks or hardware while working on seals — sealing work should stay separate from the door's mechanical systems.
- Support or block the door in the open position rather than relying on it to hold itself while seals are replaced.
Safe things to check first
- With the door closed, look for daylight along the bottom, sides, or top from inside the garage.
- With the door closed and the opener off, press a finger along the bottom seal to feel for flattened, hard, or brittle spots.
- Check the corners where side and top weatherstripping meet for gaps or separation.

Answers
Weather Sealing questions in Minneapolis
How do I tell if my alley garage's weatherstripping is shot?
A ribbon of daylight around the closed door, or a bottom seal flattened enough that it no longer springs back after you press it, both mean it's time to replace it.
Does resealing fix the snow that blows in from the alley?
It cuts down on it substantially by closing the gaps wind-driven snow uses to get in, though a very hard blow can still push a little past even a fresh seal.
