“We'd like it to match the existing siding which is square groove with 9" exposure, which I guess means 10.25" because of the overlap. Fire codes here require fiber cement, so it looks like we're looking at something like 70 bucks per 12' plank. That's several times what 9.25" siding seems to cost. Is this right, and matching old stuff is just expensive?”source ↗
“My wife and I are in talks about doing a full exterior renovation. We live in the northeast (long island, ny). We bought our house 3 years ago. Our current siding is cedar siding and it's starting to show its age (paint chipping and some boards rotting). Not sure when the previous homeowner did any touch ups”source ↗
“We are pretty dead set on James Hardie to maintain how the cedar matches the Victorian style of our home. But as I continue to do more research, I feel like I keep starting to second guess this option.”source ↗
“I understand any product is not without their flaws but am I overlooking any other options but by being so deadset on Hardie? I see a lot of mentions of LP SmartSide and one contractor we spoke with was very high on Ascend over Hardie.”source ↗
“Would love to hear people's recommendations or input because I am really going down the siding rabbit hole”source ↗
