Comments Please! New hardwood over 100 year old Pine

Your comments please !

The 100 year old pine on the 2nd floor is a bit thin and gouged and sqeeky. Plus, very little sound isolation to the floor underneath as the there is no subflooring under the pine as was standard practice back then.

OK so I had three contractors come and give estimates to lay new hardwood over the old. One thought the new wood should be layed perpendicular to the old wood for strength. The other two said it did not matter.

All would put down paper over the old floor. Two said they could put a 1/8" muffling layer for an extra charge.

On vendor said they wanted to place a 1/4" plywood layer over the old floor (and paper), and then put the 3/4" hardwood over that. OK I would have to shave off one of the doors to accomodate a 1" higher floor, I can do that...

And finaly, is the following a good idea? With my existing squeeky floor, before the vendor comes to overlay the floor, should I go through the room and individually screw in the squeeky boards to the joists? If so could I use drywall screws to do this, Like 2" drywall screws?

Much thanks in advance for your thoughts.

I know they say you can do it but if it were me I would remove the old, install underlayment, and then install new!

If you put a new floor over the old one, will the structure handle all the extra weight?

If you do screw down the existing flooring, use something stronger, like deck screws - drywall screws are too brittle for this job.
