We are working to replace our existing first floor which has a section of 3/8 hardwood by the front door. We want to use 3/4 inch hardwood. My question is the door frame comes right down to the wood now, I am assuming I need to cut out the bottom of the frame to allow room for the wider new floor? Or should we reconsider using 3/8 hardwood again?
You should buy the 3/4" - Low-cost hardwood flooring... what's the catch?.
All you will need is a jamb saw - the overkill and easy one.
The traditional jamb saw.
And I used to use the tradition saw but moved on to using a Dremel with a wood bit.
Now all that you have to do is uninstall old wood and then get a scrap of the new wood, lay saw on top of new wood on each jamb and cut. I would plan on about 5 minutes per jamb - if you have experience maybe half the time.
In support of the previous post regarding using a dremel. I came across this video for a Dremel Multi-max when I was looking for a tool to scrape up vinyl tile from a hardwood floor. This was not what I needed but shows you exactly what to do for cutting your door jambs. https://www.youtube.com/watch?v=Fyceo57suYE Hope this helps.
