Hardie board siding -longevity. ..

10 years ago

went to a home show and a vendor showed a type of Hardie board aftwr being soaked in water. .. he said the middle of Hardie board is basically cardboard. I love the look of smooth Hardie board but is this something that will last 20+ years in the northwest or will it have to be replaced frequently? anyone had it in their house for a long time and had maintenance issues?

Hardie board siding is guaranteed for 50 years (if you have a Hardie certified person install it), although the finishes are only guaranteed 15 years (which means you need to repaint every 15 years. It is a miracle product if you've ever had a home, like we did, made of the oh so horrible Masonite.

I would love to know the answer to this as we too are considering Hardie siding. If it's not the best, is there anyone out there with other suggestions for similar look with longevity?

It must be installed perfectly, and must be kept away from water.

We have had trouble with ours coming loose and "flapping" when it is windy. My husband has re-caulked every seam and every windy storm ends up having to re-nail another piece.
Our problem could very well be a bad install by the previous owners, not necessarily a common problem. (We have found plenty of stuff they did not fix/install properly since we bought the house.).

We were early adopters of Hardie. It's a great product. Who told you it was cardboard in the middle? It's a cementious product thoughout.

No, you can't leave it unpainted in the rain (it's not vinyl siding), but it comes preprimed, and jeez, paint it. We've used it several times in wet, humid Florida, and love it.

Like any other product, you need to follow install procedures, which are not all that tough. If it's flapping in the wind, it wasn't installed properly.

I think that was part of the guys complaint that it has to be installed a specific way in order for the warranty to stand. which he said was rarely done. he had a sample that was sitting on water to show how it expanded and was junk once it got wet

the center would never get wet in that manner unless you installed it wrong, Everything has a correct installation.
