Garage door bottom seal replacement in Las Vegas: the cost and the right seal

The rubber along the bottom of a Las Vegas garage door goes hard and cracks years earlier than it would anywhere milder. Here is what replacing it costs on our published price list, how to tell which seal your door takes, and how to spot the gap that is not the seal's fault at all.

Replacing the bottom seal on a garage door in Las Vegas is $95 to $145 installed for a standard 16 ft double door on our published price list, made up of $25 to $55 for the rubber and $70 to $90 for the labor. Adding the perimeter weatherstrip along the two sides and the header at the same time is $145 to $225 installed. It is the cheapest line on our whole price list, it takes well under an hour, and on a door that has been baking in this valley for six or seven summers it is usually overdue.

How much does it cost to replace the bottom seal on a garage door?

In the Las Vegas Valley it is $95 to $145 installed for a standard 16 ft double door, and that number is a line on our published price list rather than an estimate written for this page. The rubber itself is $25 to $55 of it and the labor is $70 to $90, and we show those two separately for the same reason we show them separately on every other job: it is the only way you can tell whether a price you are given somewhere else is fair.

If the two sides and the header are also dried out, the perimeter weatherstrip is $145 to $225 installed, $45 to $85 of material and $100 to $140 of labor. Doing both on one visit costs less than two visits, and on a door old enough to need the bottom rubber the perimeter is usually the same age. Every line here is on our published Las Vegas garage door price list, the same list we quote from on the phone.

One thing worth saying plainly, because it is the first thing people ask when they hear the number: a bottom seal on its own is a small job, and if you are already having us out for a spring, a cable or an opener, swapping the rubber while the door is open adds very little to the visit. That is the cheapest version of this repair there is.

Why the bottom seal fails so early in this valley

A bottom seal is a strip of flexible rubber or vinyl held in a metal retainer along the bottom edge of the door. Its whole job is to stay soft enough to squash flat against an uneven concrete floor. Everything about a Las Vegas summer works against that. Direct UV on a south or west facing door breaks the rubber down from the outside, and a garage floor that holds heat all afternoon cooks it from the inside. The result is a seal that has gone hard and split along its length years before the same seal would fail in a milder climate.

Hardness is the part people miss. A seal does not have to be visibly torn to have stopped working. Once the rubber has gone stiff it no longer flattens into the dips in the slab, so it bridges them instead, and that is where the dust, the water off a monsoon storm and the insects come in. A quick test: with the door closed, press the rubber with your thumb. A good seal gives and springs back. A finished one feels like a hose that has been left in the sun, and the marks your thumb leaves stay there.

Dust is the reason this matters more here than the seal's own price suggests. Fine valley grit that blows under a bad seal does not stop at the floor. It works into the rollers and the tracks, which is exactly the wear pattern the lubrication schedule for a Las Vegas garage door is written around, and a set of ten nylon rollers is $135 to $195 installed once they are chewed up.

How do I know which garage door seal to buy?

Look at the retainer on the bottom of the door, not at the door itself. The retainer is the aluminum channel screwed along the bottom edge, and the shape of its opening is what decides which seal fits. There are three common cases in this valley and they are easy to tell apart once you know to look.

• One channel, one slot: a beaded seal, sometimes called a bulb seal. The rubber has a single rib that slides into the slot and the bulb hangs below. Common on older steel doors.
• Two channels side by side: a T-shaped seal, also sold as a T-style or double-bead seal. The rubber has two ribs that slide into the two slots. This is what most doors built in the last twenty years use.
• No channel at all: an older wooden door, where the strip is nailed or stapled straight to the bottom edge. A flat vinyl or rubber strip, cut to length.

Then measure two things: the width of the door at the bottom edge, and the gap between the two ribs of the existing seal if it has two. A 16 ft double door needs a 16 ft seal plus a little extra to trim; a single is usually 8 or 9 ft. Take the old piece with you, or a clear photo of the channel end-on, and any parts counter can match it.

Are all garage door bottom seals universal?

No, and the word universal on a package usually means it fits the most common T-style channel rather than every door there is. A beaded seal will not stay in a double channel and a T-shaped seal will not go into a single one. Length is the other half of it: a 16 ft strip on a 9 ft door is money left on the floor, and a 9 ft strip on a 16 ft door is a gap you cannot close.

One more variation catches people out. Some doors seal against a threshold strip bonded to the concrete rather than relying on the rubber alone, and on a slab with a real dip that is sometimes the right answer. We do not carry threshold strips on the truck and they are not on our price list, so if that is what your floor needs we will say so and tell you what to buy rather than sell you a seal that cannot work.

When the gap is not the seal's fault

This is the part no parts aisle tells you, and it is the reason we look at the whole door before quoting a strip of rubber. A worn-out seal leaves an even gap or a ragged line along the full width of the door. A wedge of daylight at one end only, with the other end sitting tight, is a different problem and a new seal will not fix it.

• Daylight at one end, tight at the other: the door is hanging out of level. Usually a cable that has slipped a wrap on its drum or has stretched, so one side sits higher than the other. That is cable and drum work, and the door is not safe to keep cycling in the meantime.
• The door will not sit down square, or it binds near the floor: a flattened roller or a bent bottom track section. An off-track reset is $165 to $350 with no parts.
• The concrete itself is low in the middle: the seal is doing all it can. A taller bulb seal helps, a threshold strip helps more, and no rubber closes a slab that has settled.
• The door reverses when it touches the floor: that is the safety reverse doing its job on an obstruction, or the down-force setting on the opener, not the seal.

Doing it yourself, and when to call

On a door with an intact channel and a floor that is reasonably flat this is a genuine homeowner job: close the door, slide the old seal out of one end of the channel, clean the grit out of the slot, spray a little silicone in it, and feed the new strip through from the same end. The awkward part is always the last two feet, and cold rubber does not want to go in, so it is easier in the morning than at three in the afternoon in July.

Two reasons to let somebody else do it. The first is that the door has to be down and the retainer is inches off the concrete, so the whole job happens kneeling on a hot slab with your hands under a door. The second is the one above: if the gap is not even, the seal is not the answer, and somebody who works on these doors for a living will tell you which it is in about a minute. Our Las Vegas tune-up and 25-point safety inspection is $89, or $69 on a first visit, and the seal, the balance, the cable tension and the safety reverse all get checked in the same visit.

Either way, the visit and the written price cost nothing if you decide not to go ahead, evenings and weekends carry no after-hours fee, and we have been owner operated across the Las Vegas Valley since 2015. Call or text (702) 744-7333.

Methodology: every Angels Garage Doors price on this page is a line from our published Las Vegas price list as it reads on 2026-09-26, with the parts and the labor shown as separate columns there too. The seal types and the diagnosis notes come from the doors we work on in this valley. We checked what Google returns for garage door bottom seal replacement from a Las Vegas location on 2026-09-26: the first page is parts retailers, a manufacturer's how-to and a garage flooring company, and no garage door service company anywhere in the valley publishes what this job costs installed. That is why this page leads with the number.

A seal that is still in good condition can cause trouble of its own once the weather turns, because it stiffens in the cold and stops folding flat under the door. If yours has started bouncing the door back up on cold mornings, nothing is worn out and the fix is a setting: why a garage door reverses when closing.
