Hi--
Need some help asap!
I have hardboard siding with identical knots 61" apart. Is that for sure Weyerhaeuser? They say that is an identifying feature on their site, but don't know if the other manufacturers use something close so that I might be mistaken.
Thanks!

Thanks for the reply.
Thing is, this is siding that is failing. It's on a house in an island in the Pacific Northwest so I can't remove a piece without starting a repair process. I am trying to identify the manufacturer so I can (hopefully) file a claim. So you think this might be Hardy, not Weyerhaeuser, then? The house was built about '93.

When you say "hardboard siding" it would make most contractors imagine a type of "masonite" lap siding, whereas hardiboard is a type of fiber cement lap siding. Since you are referring to knots, you evidentally have 5/8" thick 4x8 or 4x9 sheets of siding, I'm guessing? Does it have grooves on 12" centers, like t1-11 siding has? Or perhaps grooves on 4" centers?

If it has metal joints at the end of each piece, then it could possibly be Masonite. Now, I am thinking individual 8" reveal horizontal siding. If that is the case, good luck.

It's lap siding. It looks like what you might consider Masonite but it doesn't have metal on the edges. I thought since it had those knots 61" apart that it was the Weyerheuser but any info would be really helpful.

If their web site says that's an identifying characteristic, then you must be right. I know you said that you didn't think you could get a piece off without starting a repair process, but that's something you'll have to do if you want to make absolutely sure. They clearly mark their brand name on the back of everything they make. I'd take off a piece that's up in a peak (small, easy to remove) or maybe a short piece that is on your top row. If you work carefully by prying with a prybar behind the siding to loosen the nails, you should have good success. The pieces up high will be in good shape since they aren't subject to as much weathering, and they won't be as likely to fall apart or split.

MOre than likely there is a class action lawsuit that you can become a party of for that failed defective siding, prob same crap as that Louisiana Pacific siding that settled for nearly a billion to homeowners.. It would take awhile but you may get a few grand down the road.

Yeah there is a lawsuit for this stuff, I'm just trying to verify if what I have is indeed Weyerhaeuser. They're the only one I've found that says they have identical knots 61" apart as an identifying feature, I'm just not experienced enough with this to know if that may be a common feature with other manufacturers as well..
