I am replacing the 908 casing around a customer’s 2 car garage. The garage door is 14’6″ wide. After taking the old trim off, I noticed the sheathing was water stained. After further exam, water damage had penetrated the 5/8″ sheathing and starting eating away at the header. The header is made up of 2,2x10s with 1/2″ ply sandwiched between the 2xs. Damage to the 2×10 is in the center of the beam. Damage extends left and right of center for about a foot. From the bottom , it goes up about 4″ . Within this area about 1″ of the 2×10 is damaged.
What I need is suggestions on how to fix this damaged area in the 2×10. The outside is vinyl sided and above the garage is a living space.

nk.. is that as in North Kingston ?
what does the header support ? just the roof ... a gable end ... a 2d floor ?
as a header it's pretty useless now, and the only real repair is to take out the 2x10 and replace it in place..
but check it for sag right now.. depending on the load, a pair of 2x10's with a 14' span is probably not getting it done anyways

OK but it still doesn't tell us much without knowing what loads onto it.

I'm no framer but is two 2 X 10's sufficiant to use as a header for a garage door that size.
Just currious

Sure. As long as there's nothing on top of it. ;)
In all seriousness, that's still pretty much impossible to answer Doug. If it's a single story gable-load garage or something then it could actually be oversized. But if it's a 'garage under' type situation with two stories and roof loading on it then you're probably now at the other end of the spectrum. Someone will probably try.... but nobody can really answer that yet without more information. View Image
OK, I just thought all headers above a two stall garage door were always 2 X 12's, I probably never paid all that much attention.
I actually did do some framing when I was younger but I must have had my mind on women cause I dont remember much.

That's what framing does to you Doug. Good think you quit while you were still young. ;)View Image
LOL!

Actually, the headers over our garage were 2x14. And they were sagging badly. Eave edge of a 22-foot wide standard truss/shingle roof.

Let's say it's a gabvle end wall with truss roof. A pair of 2x6 could handle that!

Since it looks like you still have good wood at the top of the 2x10, you could do a built up beam fix with a 10 foot or so long piece of 4 inch by 1/8" steel plate, bolt it to the bottom, lots of bolts (see pix, a couple of 3/8 lags every 2 inches). Clean out the old rot to bare wood and treat.
The pix is a 6" 3/16 plate I added to son's garage to double the strength (18 foot 6x14) to allow putting a storage loft above the garage.
Is the source of the water fixed? Nothing else matters until that happens.
Exactly!
You may have to pull back some of that siding to get to the source... that might even make replacement easier.
If you need to fix it in place, I'd suggest epoxying a steel 3.5" wide x10 long slab to the underside - jacking up the center on either side of the damage untile it is just arching over level again, then drilling and screwing the metal to the wood with GRK structural lags and letting it cure. The lags are there in case the wood/epoxy/steel connection fails... at 5000lbs shear per inch!Rebuilding my home in Cypress, CA

Great responses from everyone. Above the garage is a living space, used as an office. Gable roof over the garage door. No sag in the header. I think the water damage came from water running down the siding and filling up in the J channel that was used as bottom siding trim above the casing. Water overflowed the channel and soaked into the wood. Casing flashing was used but nothing high enough behind the siding to protect the wood. In addition, a cable was "hidden" in the channel thus reducing the channel's ability to let water run off.
Occupied gable up there? Which way do the 2nd-floor joists run?

consider using an LVL beam to replace the 2x
