HI group,


I bought a house built in 1925 which has oak floors. *They are not in
the best shape, with cracks and weak spots (funny the home inspection
didnt really call it out as a problem). *Additionally, it has been
refinished as many times as it can take so we are going to replace
it. *There is no subfloor, however. *My question is: *could you have
the new floor installed right on top of the old floor (making it
become the subfloor) or would you just have both installed brand new?
Or just a new floor without a subfloor?


This is for two rooms on the ground floor that is over a basement.
Currently we hear the boiler and see through cracks, so I'd like
something very sound and as sealed as possible. *Not married to any
particular type of wood so if one type is better I'd love to hear
about that too.


Thanks in advance to this very generous group!


Consider laminate flooring with a sound dampening underlayment. It can be
easily installed over your existing floor. Squeaks and "mushiness" should,
of course, be dealt with while you can access both sides of the floor.


Laminate is UGLY, doubly so in an older house- it just looks WRONG.
Can't say for sure without seeing it, but old floor would probably work
fine as a subfloor. Fix the squeaks and any mushy spots, and shop around
for a deal on real hardwood, preferably something narrow to fit with the
age of the house. I find it hard to believe there is NO subfloor, unless
the place had an abandoned remodel. House of that vintage would usually
have 1x4 or 1x6 plank, nailed at 45 degrees to the joists. OP, where are
you? There were different practices in different areas.

Most old houses with oak floors have subfloors; usually 1x4 at 45
deg.........

but all vintages of houses were built w/o subfloors.

My house (1930) has oak flooring & 1x4 subfloor but my next door
neighbor's house (1952) has oak flooring and NO subfloor.
It is currently owned by the son of the original owner...so no
remodel.

One issue with using the old floor as the subfloor.....not at 45 to
the joists (which is a minor nit)

OP- depends on your budget.....

either use the old floor as a subfloor or

remove old floor, add new subfloor (plywood not OSB) and install a
real wood floor.....laminate sucks.

A thicker (3/4") solid wood floor would most likely be way cheaper
than the second option of adding a subfloor.

You bought a period, "charm" home, don't put in laminate and ruin the
look.

A new floor w/o a subfloor would be a bad idea, why tear up the old
would floor & not replace it...either use it as a subfloor or tear up
and install a proper subfloor.

I wonder how the floor installer handled the wall / floor interface
condition? Wood floor goes under wall sills?


cheers
