Depending on the type of job it is we would rip off the old siding and replace with new. Some siding do not require us to rip them off, it just depends on the type you have now. If you don't have to rip it off it will save you money. We will install your new siding with insulation underneath. We will make sure the right type of flashing is there to prevent water leaks. We install all types of siding from wood ship lap to vinyl to steal. You let us what you'd like.
