One of the contractors, whom I think is honest, is warning me again
using Maple for my hardwood floors. He says that he's see no end of
expansion in the summer and contraction in the winter issues.
Basically, large gaps in winter. And if put in during the winter:
significant buckling during the summer. "except if you use
'engineered maple' which is a thin veneer which only allows
refinishing once".
I have no idea. Can anyone shed any light on this?
THANKS!!!!!!!!

Cost isn't all that much of an issue in this application, since there
isn't much choice. However, it it were a constant problem the cost
wouldn't matter; it simply wouldn't be used. I would agree that if
it's installed properly, there is unlikely to be a problem but it
*can* happen. I'd still use it if it's what I wanted.
Find a better contractor who knows how to properly install HW florrs
with appropriate expansion gaps under the base boards.

Was it microbeveled, or did it allow for smooth butting (without an
extra sanding/refinishing)? The beveled look is just not something I
like at all.

I have seen buckled basketball courts. I remember the one in our
grade school would come up at least a foot, in one corner, each
summer. It took them a few years to get it fixed.

And I grew up in a house in Montreal that my grandfather built in
1930. My cousin lives there now. Maple floors are as good as ever, &
they have been sanded and redone a number of times.

Do you have any access to birch flooring? Looks a lot like maple, is
usually cheaper and my experience somewhat more stable than maple.
There are literally thousands upon thousands of homes around here with
birch floors. (Great Lakes area where we know a bit about humidity,
although nothing compared to some of the Gulf-bordering states.)

Several houses in my area have 50- 80 yr old maple in kitchens, these
houses are top quality, so it can be done.

Central Florida...
Summers are hot. Growing hair causes profuse sweating
Winters are dry enough that my skin cracks
I put solid, 3/4" x 2 1/2" maple in my wife's office room (12'x16') about
ten years ago. No gaps, no buckling, no problems.

Not sure of the difference between beveled or microbeveled.
Basically most of the engineered wood I've seen here in the UK has a small
bevel on the long sides and none on the ends. We butted the boards together
with no sanding - they were supplied prefinished.

Maple makes a beautiful floor, but does take longer to stabilize ... up
to a few years in some climates.
Acclimation, in the environment it's going to be installed in prior to
installation, is VERY important with maple; it performs better in an
environment that doesn't change much in RH; when finishing you don't
want to just throw stain on it as it blotches ... much better to use a
clear topcoat; and you better expect seasonal changes to cause gaps
during periods of low RH.
IME as a builder, if maple flooring buckles, it has been installed
improperly by not taking into account its inherent dimensional
instability ... gaps, you will most certainly have to live with even
when properly installed. You may also find you have to hide larger
expansion gaps around the perimeter with thicker baseboard and shoe
molding, which can be an additional, unplanned for expense.
Simply put, unstained maple makes a beautiful floor providing you know
what to expect and are willing to live with its vagaries for a couple of
years or so, or longer ...
Just my experience ... YMMV.

Your contractor might be honest .. but wrong. I grew up in a house in
Chicago that my Grandfather built in 1911, and the Maple floors in there
look as good today as ever. They have been sanded & refinished once
that I know of. Get an installer that knows his stuff .. sounds like
your contractor is unskiilled.uninformed with respect to this topic.

I am also in NH, on the coast. Been here for 2 years with maple
floors. No problem, other then then wondering if I can pull out the

I put down 3000 sq feet a few years ago. The 2 1/4 inch wide stuff
is great. However, the 4 inch stuff does expand and contract with the
season. No buckling, just compression that makes each board thicker
at the edges than at the center (Poisson effect). It looks bad when
you view it from the side when light comes in along the board
length. When viewed from straight down it looks and feels ok. I did
leave expansion room at the edges, but the rooms are too wide. In
addition, it can't expand because the staples hold each board in
place. It can't buckle because the staples hold it down. It's really
a shame because I acclimated the wood before putting it down and I
put 30# felt paper under it as a vapor barrier. Any ideas? Will
it ever stop?

"A bit more stable" ? Do you have any (at all) of the buckling/gap
results with birch?
The contractor is suggesting oak, but that's just a look I am deathly
tired of.

That's nearly an inch thick, so it /must/ be including the plywood
depth. How thick is actual maple on it?

We have an "Engeneered" Maple floor in our master bathroom. Absolutely no
problems in the last 6 years EXCEPT where the water drips down behind the WC
from the shower curtain, if the curtain gets pushed outside the tub when
getting out of the tub. You may want to consider an Engeneered Maple hard
wood floor.
The veneer is about 1/8" thick.

If you use the right kind of engineered wood you can refinish it lots of
times.
For example here in the UK you can get 21mm thick engineered wood with T&G
joints. This can be resanded as many times as solid wood with T&G joints.
(eg it's the T&G joint that fails first).

Listen to the man. Maple is not the most stable of woods, and it's going to move quite a
bit in response to changes in temperature and humidity. If this is a problem in your area
and you *must* have Maple I would suggest following the man's advice and considering
engineered flooring instead.

There are thousands of basketball courts all over the country which
don't seem to have such problems.
Unless it's very wide plank and/or one of the softer maples I can't
imagine it being an issue if it's installed properly (which includes
acclimatization, house already in climate-control stage, etc.).

For every one w/ a problem I'll bet there are hundreds that haven't had
any.
As far as personal experience I know of six elementary schools, two
middle schools and two high schools here alone that have never had any
problems in from 20 to 80 years.
More than likely there was a specific problem w/ that installation that
caused a problem of that magnitude and I'd certainly not expect anything
like that in a residential installation.
It's not like there _can't_ be an issue but I'd ask for evidence they're
particularly trouble-prone before I made any issue over it as a
material. If they had been such it's unlikely they would have continued
as the floor of choice for so long for such facilities where costs are
an issue.

(Hint--no, never...) I simply pointed out there are oodles of maple

35 year old maple floors in my house - insignificant
axpansion/shrinkage issues. I get a squeak or two in the winter if it
gets too dry

I'm in NH and we have solid red oak floors (sorry, not maple) that do
not have gaps in the winter, or buckle in the summer. Of course, we
also have partial humidity control inside the house :-)

Yes includes the plywood. The top wear layer would be a bit more than 1/4"
say 5/16". It varies from make to make. You can also get a 14 or 15mm
versions. Same ratio of ply to hardwood applies - eg the wear layer is
between a quarter and a third of the overall thickness. Good prefinished
engineered oak can sometimes cost more than solid oak.
We installed 200 mm wide, 21mm engineered oak in our house over UFH. Came
pre-finished with Osmo Polyx Hardwax oil which is easy to recoat.

I'm seeing lots of problems:yes vs problems:no, but I'm not seeing
anyone talk about local climates. Hardwood floors in CA are seldom a
problem cuz it rare gets below freezing in most of the state. I'm
sure that's not the case in MN or ME.
