I'm having some siding repairs done by contractors. When they took the siding sheet out, they found out that my house has no house wrap between the frame/wood and the T1-11 siding sheet. There was some rotten wood under the siding, and the 2 windows on the wall don't have window flashing.
One of the guys said that they would never install siding sheets without the house paper. They told me that their boss looked the project over and wants to offer me a discounted rate to reside the whole wall since the building hadn't been wrapped originally and that side of the house gets the most weather (this is true).
Is residing the entire to install the house paper worth it? Are they just trying to upsell me?
Most of the wall's siding looks good, except for the rotten part that needed repair. The house was built in 2000.
I'm doing a siding repair because it's cheaper. I don't know much about home repairs. Some insight would be appreciated.
