Garage door weather seal replacement in Raleigh

A garage door weather seal is the rubber or vinyl strip along the bottom of the door, plus the stop seal around the sides and top. If you can see daylight under the closed door, feel a draft, or find leaves, water or pests inside, the seal is worn or the wrong size. Replacing it is one of the quickest fixes we do.

The three seals on a garage door

• Bottom seal. A rubber or vinyl strip held in a channel along the bottom edge of the door. It presses against the floor when the door is closed. Common styles include T-end and bulb, and the new one has to match your retainer channel.
• Perimeter stop seal. The vinyl or rubber strip on the side and top stops that the closed door rests against. It blocks light, wind-driven rain and insects at the edges.
• Threshold seal. A rubber strip fastened to the floor where the door closes. It makes up for uneven concrete and helps hold back water on a sloped apron.

Signs your seal has failed

• Daylight under the door. Turn the garage lights off, close the door, and look along the bottom from inside.
• A seal that is cracked, flattened, curled or torn loose at one end
• Gaps at the corners where the bottom seal meets the side stops
• Water on the floor after a heavy rain, or pollen, leaves and grit drifting in
• Ants, mice or wasps getting in around the door
• A garage that runs hot in July or cold in January, especially under a bonus room

Why Raleigh wears seals out

Heat and humidity do the damage. Long humid summers soften vinyl and rubber, then sun and temperature swings harden and crack them. Spring pollen and mud pack into the seal channel, and sprinkler spray and wind-driven rain from summer storms keep the bottom edge wet. A seal that was fine at installation can be stiff and split after a handful of seasons. We also see wood jambs swell in the wet months, which leaves gaps along the side stops.

Pests, water and drafts

• Pests. Mice can get through very small gaps, and ants and wasps look for the same ones. A good seal closes the door gap. It does not replace pest control, but it removes the easiest way in.
• Water. A bottom seal handles splash and light runoff. A threshold seal helps where the apron slopes toward the garage. Neither is a flood barrier, and standing water needs drainage fixed outside.
• Drafts. If the garage is attached, a sealed door helps the shared wall and any room above. An insulated door and a good seal work together.

What we do on the visit

We inspect the retainer channel and the bottom bracket, measure the door width, and fit a new seal cut to length. We check that the door sits flat on the floor, adjust or replace the side stops where they have pulled away, and test the closed door for light and drafts. If the bottom panel is rusted through, a seal will not hold, so we will tell you and point you to panel replacement. A seal check is also part of every tune-up, and the rest of what we fix starts at garage door repair.

Choosing a seal

Rubber and vinyl seals both work, and the better choice depends on the door and the gap. Rubber tends to stay flexible through temperature swings. Vinyl holds its shape well but can stiffen with age. On an uneven slab we use a taller or double-bulb style so it still meets the floor, and where the apron slopes toward the door we add a threshold seal.

Side and top stops

The wood or vinyl stops around the door get less attention than the bottom seal and fail just as often. Nails pull out, paint cracks, and in the wet months wood swells and rots at the base. We check the stops for gaps and soft spots, reset or replace what has pulled away, and fit new stop seal along the sides and top so the closed door meets them evenly.
