Repairing masonite

I post it before about removing masonite siding from a building, however, this time I need to actually repair a section that is bad. The masonite siding I have is 12 in on Center vertical Style. What should I do to repair the damaged portion of this siding that is at the bottom of the boards? The sheets of siding measure 4 foot by 8 foot. I saw where perhaps I could cut the damaged area out and replace it with fresh new siding but I was unsure if that would look good and work correctly. I would hate to see more damage occur from me cutting that out. My problem is that the signing is so hard to remove I'm trying to avoid the headache in doing so. I would appreciate your suggestions and also if I do cut this out how can I ensure that I am doing a straight cut and what would be the best tool for cutting?

Masonite doesn't repair well and moisture is it's arch enemy. If you cut out just the bad and put in a patch piece it will probably need flashing. . Pics would help us help you.

Depending on how much is bad, I'd consider cutting all across the bottom and replacing the masonite with a 1x6 [or whatever size works best] with Z flashing between the new board and the siding.

The new siding they sell is identical except for one spot and you can tell that it's different. So I guess I need to just remove the whole thing but that will be such a headache.

I don't even know if this is masonite siding. Nobody can tell me exactly what this is called beside reverse board and batten or t-111. I really need help here I have to figure out what to do with this siding and I have to be able to do it in myself without paying a contractor. Nothing I have tried so far has allowed me to take the siding off or make repairs every time I mess with it it's a struggle. I am completely out of options and I'm pulling my hair out and I'm ready to burn down my house because it is that frustrating.

The odds are even if you know the manufacture of the siding, that exact siding will no longer be available. It's not uncommon for slight differences to be made in manufacturing over the years to make a new panel no longer match up to the old one.

Perhaps if you posts some pics showing the damage and where it is we can offer more help.

I'd cut off the offending part of the bottom to accomadate a 1x that is tall enough to replace the damaged portion of the siding. Use a Z flashing between the masonite and the 1x. That will create what is commonly called a belly band. Because masonite is so moisture sensitive I'd prime/paint the cut edge before installing the Z flashing.

I would be using a 1x12 in that case. Thats what my neighbor is doing (our houses are identical) and it looks tacky. I would then need to follow that pattern and do the rest of the house.

Not sure there is much alternative other than replacing full panels or residing.

It should just be nailed on although I suppose they could have also used an adhesive. You'll just have to work at until you get it. Once you figure out what works best it will get a little easier.

Cut it vertically into smaller pieces. Preserve the tongue and groove sides by cutting the nails behind the siding... don't use a pry bar or cats paw on the pieces you need to save. Cut the nails on the back side with a sawzall.

There are a lot of meals here. Once I remove one set I can't get anything behind it to remove the next. This stuff isn't very flexible. I'm trying to save as many sheets as I can so that I can make repairs but I'm going to end up not having that luxury if I'm not careful.

That should say nails and not meals.
