questions about re-siding an older home
We want to use James Hardie lap siding for our 1995 home that needs resided. The current siding is a composite 4x8 sheet wood that is deteriorating rapidly.
Local siding companies are telling us that they want to install the James Hardie on top of the composite wood without removing the composite wood. We are troubled by this suggestion because we believe the composite wood will continue to deteriorate under the James Hardie and will create a poor base that will cause the James Hardie to ultimately fail.
Can you tell us what the correct installation method would be in this scenario?
We've been reading reviews on James Hardie lap siding and watching videos and based on what everyone is saying we're almost tempted to do it ourselves. I have helped others re-side a house with vinyl siding and I'm a moderately good renovator. Does anyone feel the reviews and videos are making it look easier than it is?
All advice appreciated.
Is the 4 x 8 siding the only layer? It may be this is also the outer sheathing for the house. Before you have it removed you should verify if there is a sheathing layer under the siding.
"Is the 4 x 8 siding the only layer?"
... BUT, I just received an information .pdf from the James Hardie manufacturers and they say remove all previous siding and install direct to either sheathing or to 2x4's if single wall construction. 1" foam insulation can be added prior to installation if desired.
So .. guess that's my answer if I want to follow the manufacturer's advice.
I would never install any of the Hardee products directly over the studs.
Reasons being, that would take away any of the shear strenght in the wall.
(resistance to swaying or racking.
Hardee is a very fragile product unless it's laying on a flat surface. You'll notice a lot of damaged pieces even before it's installed. If there nothing to back it on a wall you could just kick the wall in with your foot, a flying stone from the lawn mower will go right through the wall.
Could you post a picture of your siding, from 12' away?
