Hardi Plank worth considering?
The back of our 1940 house is an 1992 addition (not built by us) and supposedly cedar. We had it completely painted in 2007. We are renovating the kitchen and discovered extensive wood dry rot. We had our contractor's assistant "fix" the rot on T&M which became more than double the original amount (still mad about that) and way more than we ever expected. We are getting the gutters fixed as that seems to be part of the problem but i still need to hire a painter to paint the repairs. Which, according to a painter today, is another 1500 on top of the 2000 for the entire job! And while i was walking around with the painter i found more dry rot!
So we are staying here a while and i'm wondering if we should just bite the bullet and replace the siding with cement boards. The rest of the house is brick and this part of the house is north facing and pretty shady. The addition is roughly (it is L shaped) on average 15x 35 ft.
Any thoughts on how much it would cost to replace with hardiplank and if it is worth it long term? Any downsides to it? Would we get better insulation? thanks!
