Rotten door frames

[Jacko264]

Hi all
my garage door frames are rotated at the bottom where they stand on the concrete .
I am about to renew the frames but what is the best way to stop it happening again .
i was thinking of standing it on plastic to stop water getting up the grain .
all wood is painted
thanks
Graham

PVC trim.

Can you explain a little more please

Use pvc boards instead of wood. Azek and veranda are both common names.

It machines easily, takes paint and can't rot

You mean put psv over the wood ?
that may work I will have to think about it

No, instead of wood.

Or if the rot is confined to the bottom few inches, just cut the bottom few inches off, and replace with new wood or pvc.

 

[Jacko264]

The wood is 225 x 40mm x2.2 long
can you get pvc as big as. That

 

[Bunsen Honeydew]

Probably. You will have to check for yourself to see what may be available near you in the UK.
Search for pvc trim or pvc board.
Or you could just cut the new frame short enough so it does not contact the concrete, then caulk the gap.
Pvc will cost more than wood.

we might have a miscommunication. I believe op is talking 2x material.
JackO is the wood structural framing and sitting on the ground or concrete? If so we use pressure treated wood. Others were talking about what goes over that for trim boards which is normally 3/4 inches thick.
Pictures might help as I know there are a lot of old buildings over there.

Pictures, I think we're having terminology differences.

 

[Jacko264]

There you go

Appears to be more structural than trim. One door has been patched in already, see the diagonal line?
Pressure treated wood will give you a longer lasting repair. Looks like all you need is to patch the bottom again. PVC won't work for structural. If you can keep the wood from direct contact with concrete, so much the better.

The builder of my attached garage put strips of metal flashing between the concrete and the PT garage door 2x‘s. Dunno if it makes a difference as I repaired one side last year due to rot and now need to do the other.

When I repaired one side, I cut off a few inches and replaced it with a glue up of PVC in hopes that I never have to replace it again.

I have a strip of 8mm plastic I was thinking of putting between the wood and concrete
plus plenty of sealer

That will help. Keep the wood as isolated from dampness as possible.

Best I have found for my area is to stop the door wood 1/8” above the concrete to allow moisture a break line to escape, then cover with trim coil not caulked at the bottom. The building with a door like this with a concrete apron outside does fine even with rain splash back after 15 years, and the barn door 7” above grass without the trim cover lasted five years. I just replaced the brick mold on it again last week. Time to gap it add the trim coil.

Rotated. You mean rotted, rotten.
Had a similar door which split a cable skimmed my head and smashed a double glazed window.
Had the whole thing renewed, door and frame £700.
Timber frame clad with pvc angle section.
Obviously the timber was a bit slim so it's offset and packed out on one side.
Been up 14 years.
I agree with some options advised here but replace as much timber as sensibly possible - treated and make sure the ends are well taken care of.
Keep the doorspring lubricated and properly tensioned.

Cut off the bottom and get those metal boxes for patio posts. Not sure I’ve seen them In 2x though.

I am surprised that nobody has mentioned BONDO, I frequently use it for cosmetic repairs.

Sounds like we're going back to structural 2x4s. And they'll be in contact with moisture again (based on photo).
Pressure treated. Honestly, I'd coat the bottom half of the 2x4s in epoxy or polyester resin, which will substantially help these live longer in a wet environment. You have to paint them, either polyester or epoxy is UV stable.

Hi
I have renewed two pillars and put 8mm plastic on the bottom painted first then lots of sealer
one other I have spliced in a new bottom part again on plastic paint and sealer
the forth pillar is in good order
