What do you need?

What does garage door panel replacement involve?

Garage door panel replacement means swapping a damaged section of the door for a matching one. The technician identifies the make, model, height and design of the door, orders a matching section where one exists, then removes the damaged panel and fits the new one. Hinges, rollers and struts are moved over or replaced, and the door is rebalanced afterward, since a new panel can weigh a little differently from the old one.

Matching is the hard part. Older and discontinued doors may no longer have sections available, and a close match in color can still look different in sunlight. If a matching panel is not available, the better choice may be a new door. Replacing a bottom section is the most common job, since it takes the most abuse.

What damages garage door panels in Minneapolis?

The bottom panel suffers most. In winter it sits in slush, salt and packed snow, and a plow berm at the end of the driveway can press right against it. Over time steel panels dent and rust along the bottom edge, and thin or brittle panels can crack when something hits them in deep cold.

Other common causes of damage include:

  • Vehicle bumps and shovel or snowblower strikes.
  • Moisture trapped in a damaged panel that freezes and expands.
  • Rot in older wood doors, especially along the bottom rail.
  • Fading, peeling or delaminated skins on older doors.
  • A door that has come off its track and bent a section as it moved.

A damaged panel is more than a cosmetic problem. It can weaken the door, let cold in and make the door heavier or out of balance.

How does garage door weather sealing work?

Weatherstripping is the set of seals that closes the gaps around the door. A rubber or vinyl strip at the bottom presses against the floor. Seals along the sides and top fill the gaps against the frame. Some doors also use a threshold seal glued to the floor when the slab is uneven.

Seals harden and crack with age, and cheap ones can stiffen badly in deep cold. A seal that no longer flexes will let snow blow under the door and can freeze to the slab. You can often spot a failing seal by the light that shows around the closed door, by drifts of snow on the inside floor or by a cold, drafty room above or next to the garage.

Good seals cannot promise a warm garage, but they cut drafts and keep out slush, leaves and pests. They work best on a door that is straight and well balanced.

One damaged panel on a sound door is usually a repair worth considering. If several sections are damaged, if the door is old or if matching parts are not available, a new door often makes more sense. Our new garage doors page covers that choice. The price of panel work depends on:

  • How many sections need replacing.
  • Whether a matching section can still be sourced, and how long it takes to arrive.
  • The door's material, insulation and finish.
  • The condition of the hinges, rollers and struts.
  • Whether new seals, a retainer or other hardware are needed.

A technician can compare the cost of a panel with the cost of a new door and should give you both in writing.

How long does it take, and when should I call?

Once a matching panel is in hand, a single panel swap can be a short job. Ordering the section is often the slow step, and it may take days or longer, so ask for an honest estimate. Replacing seals is usually quicker than replacing a panel.

On the day, expect the technician to inspect the whole door, quote the work in writing, fit the new panel or seals, rebalance the door and test its travel and safety reverse. If you plan to paint a new panel, ask about the right finish and how long to wait.

Call when a panel is cracked or rusted through, when daylight shows around the closed door or when snow keeps blowing under it. If the damage came from a door that jumped its track, our cable and track repair page explains that side of the job. You can also visit the home page.

Questions about garage doors in Minneapolis

Can I replace just one garage door panel?

Often, yes, if a matching section is available for your door. Older and discontinued doors can be hard to match, and a new panel may differ slightly in color. If the door is old or several sections are damaged, a full replacement may be the better choice. The technician can show you both options in writing.

Why is the bottom panel of my garage door rusting?

The bottom edge sits in slush, salt and standing water through a Minnesota winter, and a worn seal lets moisture sit against the steel. Over time the paint fails and rust sets in. Keeping the seal in good shape and rinsing salt off the base in spring can slow it, though it will not stop it forever.

How do I know if my garage door seals need replacing?

Look for daylight around the closed door, snow or leaves on the inside floor, cracked or flattened rubber, or a seal that freezes to the floor. A drafty room above or next to the garage is another sign. Seals are one of the cheaper parts to replace, and fixing them can cut drafts.

Will new weatherstripping make my garage warmer?

It can reduce drafts and keep snow out, but it will not heat an unheated garage. How much it helps depends on the condition of the door, the floor and the walls. An insulated door with good seals helps more than seals alone. Ask the technician what to expect for your garage.

Should I paint a replacement panel to match?

Often a new panel arrives in the factory color, and an older door may have faded. Some owners paint the whole door so the colors match, but the finish needs to suit the material. Ask the supplier about suitable paint and about how long to wait before painting a new panel.

Do dented panels affect how the door works?

They can. A badly dented panel can weaken the section, put stress on hinges and make the door sit out of line. It can also let moisture in and change the weight of the door, which affects the spring balance. Have a technician check any impact damage before you keep using the door.
