    Default How should I repair this pergola?

    A couple of the rafters and one cross beam of this pergola are rotting at the joins. Other than this it seems reasonably solid and in good condition. I'm wondering if it makes any sense to prop the beam with a temporary support, cut the rotted end, and splice in a new piece with a half-lap. Then I can replace 2-3 other rafters and be done with it.

    I'm wondering whether this thing was a DIY job by the previous owner - it's just the use of joist hangers that seems a bit odd, I would have thought you would just fasten through the beam and into the ends of the rafters, but I'm not a carpenter

    It used to have a grape vine growing up and over the part that has no roof over it. That was dead and I've since cut it down. The roofed part provides some decent extra shade over the living room windows. I would probably add some more iron sheets over the other part that is currently not covered. It's useful for keeping things mostly out of the rain.

    There's so much rot you really need to start again. Up side is that the stirrups look ok

    That's an accident waiting to happen, beyond repair, best fix is a can of petrol .

    Knock it down, there is nothing worth saving on it, rebuild it and make it bigger so it's actually useable as a shade structure.
    Plants and timber structures never mix, I have seen so many pergola damaged by various vines growing over them, they just hold moisture in and rot all the timbers.

    While you're there, the barge boards these need some serious attention, so are the pavers, need pulling up and relaying, and the paint definitely needs some attention.

    Below is one I replaced the posts and main supporting beams as the plants had held water on them for years, these were H3 and destroyed, in under 6 years.
    The posts and parts of the beam that had no plants growing on them were still in perfect condition, every section there was foliage the timber was damaged.

    Ok, that's another project added to the list! I knew the bargeboards needed replacing, and the fascia in a couple of spots. The paint I'm planning to try stripping and leave it bare. The brick pavers are definitely a DIY project by the last owner. What's wrong with them?

    Might just be an artifact of the photo, the majority of it is flat and level. The bit at the bottom center where it looks wonky is where it transitions to a straight path.
