Ask any Dupo tech and they'll tell you the climate decides what fails.

Run down the service log for Dupo and the same repairs repeat: warped or sagging panels after years of freeze-thaw, cold-snapped torsion springs in deep winter, loosened hardware from wide seasonal swings, and doors frozen to the slab on cold mornings. We carry every part needed to close them out in one trip.
Weatherstripping is the often-overlooked component that determines whether your garage is sealed against drafts, dust, pests, and water. There are four distinct seal locations on a typical door: the bottom astragal seal between door and floor, the side jamb seals between door edges and door frame, the top header seal between door top and frame, and (optionally) a threshold kit on the floor itself. Each wears or fails on its own schedule and contributes to a tight seal.
We replace all four where needed in a single visit. Bottom astragals come in T-style, P-style, and bulb profiles to fit any retainer; we carry all three. Jamb seals are vinyl flap or brush, with the flap style being more common locally. Threshold kits sit on the concrete floor and create a positive seal even when the floor has settled or sloped slightly. Most homes can benefit from at least one of these upgrades.
Typical visit: 45–60 minutes per door. Installation is straightforward — measure, cut to length, fit and secure. The biggest impact is usually the bottom seal, especially on older doors where the original seal has cracked, hardened, or worn through from floor contact.
Signs you need garage door weatherstripping
Visible gap under closed door
A pencil-width gap or larger means the bottom seal is worn, cracked, or compressed. Replacement restores the seal.
Drafts in the garage
Air movement around the door edges with the door closed indicates failed jamb or header seals. Side gaps let cold air, dust, and pests in.
Water intrusion during rain
Water under the door during heavy rain points to either bottom-seal failure or a low spot in the floor that a threshold kit can fix.
Pests entering the garage
Rodents, lizards, and insects find any gap. Effective weatherstripping seals them out.
Old or cracked existing seals
Bottom seals harden and crack at 5–8 years. Side and top seals last longer but eventually fail. Visible cracking means replace.
Common causes & what we fix
UV degradation
Vinyl and rubber seals harden and crack under intense sun exposure over years. Replacement with UV-resistant compounds extends life.
Floor wear
Bottom seals contact the floor every close cycle. The seal compresses, deforms, and eventually tears.
Concrete heave or settlement
Floors that have settled or heaved create gaps under the closed door. Threshold kits compensate.
Pest damage
Rodents chew through bottom seals to enter. Once chewed, the seal must be replaced.
Improper original install
Builder-grade installs sometimes skip jamb seals entirely. Adding them is a quick upgrade.
