Covering up your home’s old siding is rarely the recommended solution. To do the job right, the old siding should be removed in entirety.
This gives many benefits to you as the homeowner:
1) Removing the old siding allows the installation crew to inspect the substrate (i.e. sheathing) for any damage that may have occurred (rot, mold, etc.). Of course, should there be rotten wood for any reason, the wood should be replaced. A common gauge for replacing the wood is whether or not it can hold a nail.
2) Not tearing off the existing siding will add thickness to your walls. This will give your windows a more recessed look; a look most homeowners do not find attractive.
3) Tearing off the existing siding gives a flat surface for the replacement siding to be applied. This will result in a better-looking installation that is relatively free of leakage.
There are instances where tearing off the existing siding is not necessary (although highly recommended). If you do not have any mold or rot issues on your existing siding, the likelihood of having these issues in your substrate is highly unlikely.
The benefits of going over your existing siding include:
1) Saving money on the removal of the existing siding.
2) Your job may not require a dumpster, or will require a much smaller dumpster, saving you additional money on your siding project.
3) Going over existing siding can provide additional insulation to your home.
As each home is different, each siding project needs to be evaluated on its own merits. The best course of action is to contact an expert on replacement siding and see what the best course of action is for you, your home, and your budget.
