Should vinyl siding be overlayed on old siding?

milju asked:
I got a price range of 8k to lay new vinyl on old siding. The contractor said that won’t be a problem, but I believe it is. Shouldn’t it be better to take off the old siding and install a barrier? I think the guy just wants to do a quick install.

Anybody with this type of experience? Problems or issues? All responses are appreciated

vinal siding can be put over just about any other siding, except other vinal siding, then it must be stripped

I wouldnt do it.Ive never heard of that practice and yes i agree that you would have to have some type of vapor barrier inbetween the two It is incredibly difficult to get new siding installed over old to look right considering the depth of existing windows and doorframes. That is not only a concern aesthetically. This will also affect the flashing that keeps water away from your house, windows and doors.It sounds like a cheap way to do it that in the long run not last.Think of it like laying new carpeting directly ontop of old carpeting,somethings just cant be done. It will be worth the money to do it the proper way.

They make a syrofoam insulation that will match your existing siding to create a flat surface that is nailed or stapled onto the existng siding. Then if you choose or code requires add Tyvec or similar product over that and then add vinyl siding, this is a typical install. If you have old wood siding, sometimes that is the only thing keeping the insulation in the walls. If it is aluminum siding then you can pay a little extra to have it taken off and then take it to be recycled.

I would want it taken off…
Not only that, you will get some decent money for it if it’s aluminum….

It is common practice to apply new vinyl overtop old siding. They often cover the old siding with a thin layer of foam board to get a flat surface. There is nothing wrong with this method if the doors and windows can be trimmed out looking good.

I agree with you that the siding should be removed. It is very important for energy efficiency to have a good air barrier, and this is the perfect time to get it correct. Question contractors about air barriers; some won’t know what you’re talking about, others will talk around it, some (I hope) will know what you want, and those are the ones you want to do the work. Still get several references prior to signing up. I have seen & heard many horror stories with siding work.
