Garage Door Garage Door Weatherstripping Longmont, CO
Homeowners across Lake Valley Estates, Ken Dale, Marnett and Northwest Acres call us for garage door weatherstripping because we know Longmont. The common drivers locally are cold-snapped torsion springs in deep winter, debris-blinded safety sensors, frozen, sluggish openers in unheated garages, and doors iced to the slab on cold mornings — and we fix the cause, not just the symptom.
Weather matters more than most Longmont homeowners expect. Local conditions — a high-elevation mountain climate — cold, snowy winters, dry, mild summers, and large elevation-driven temperature swings — drive heavy snow load and ice on doors and tracks, freeze-thaw that cracks seals and loosens hardware, and pine debris and grit fouling rollers and sensors, so we recommend hardware and seals suited to Colorado's high country.
The short list of what goes wrong on Longmont garage doors: cold-snapped torsion springs in deep winter, debris-blinded safety sensors, frozen, sluggish openers in unheated garages, and doors iced to the slab on cold mornings. Whatever's on yours, the diagnosis is free on most repairs and the quote is in writing.
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.

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.

Local weather drives most of the repairs we run in Longmont: with high-elevation mountain climate — cold and heavy snow load and ice on doors and tracks, freeze-thaw that cracks seals and loosens hardware, and pine debris and grit fouling rollers and sensors, the common failure modes are cold-snapped torsion springs in deep winter, debris-blinded safety sensors, frozen, sluggish openers in unheated garages, and doors iced to the slab on cold mornings. Our Longmont trucks stock the parts those conditions wear out first, so most jobs are a single visit.
In Longmont it is usually cold-snapped torsion springs in deep winter — and because the area has mostly suburban single-family homes with attached garages, alongside pockets of older in-town housing, we also see a lot of debris-blinded safety sensors.

If your floor has settled, sloped, or shows water intrusion during rain — yes. If the bottom seal alone gives you a tight close — no, the threshold is optional.
Bottom seals are DIY-friendly if you can match the retainer profile and trim accurately. Jamb and header seals are more fiddly but doable. Threshold kits require precise alignment and good adhesive technique.
Bottom seals: 5–8 years in intense sun. Jamb and header seals: 10–15 years. Threshold kits: 10+ years. Indoor-conditioned environments last longer.
