Wrong gauge staple. If the
manufacturer requires 16 gauge
staples for the installation, then
use 16 gauge staples. 18 gauge
won't give the same holding
power as there is less staple
surface that comes into contact
with the hardwood and plywood.
Slippage causes squeaking.
Follow the manufacturer's
recommended nailing pattern.
Good products have clear
installation instructions (and
real warranties). Don't over
nail, it can cause problems
just like under nailing can (see
NFCA inspectors photo above).
Manufacturers should be clear
regarding fastener patterns,
including the distance of the
last fastener from the end of
the boards.
Nailing hardwood over top of a
crawl space is a risk. Changes in
moisture and temperature levels
lead to micro movement in the
wood flooring.
"Cover the subfloor with a
quality, 15 lb, asphalt building
paper, over lapped 2 to 4." This
helps keep dust out, and retards
moisture from below.
Moisture. Take a minimum
of 20 moisture tests per
1000 square feet, average the
results and document to protect
yourself should there be a floor
inspection in the future. Don't
just surface test, test deep into

www.bcfca.com

the subfloor, this will reveal
moisture that will potentially be
attracted to the hardwood after
installation. This is why many
floors that appear great for a few
weeks after installation suddenly
start to exhibit problems.

Flatten the subfloor to 3/16"
over 10' (or 1/8" in 6'). Deflective
(up/down) movement stresses
joints and staples leading to
undesirable movement.
Acclimate the wood to eventual
living conditions for a minimum
48 hours. Never deliver the
flooring to site conditions
that have not been carefully
checked, confirmed dry and are
at Relative Humidity (RH) and
temperature levels the home
owner will maintain.
Leave expansion spaces
(according to manufacturer's
specification, usually 1/4") at
the floors perimeter and at all
obstructions such as railing
posts, door transitions, and fire
place hearts. Undercut door
casings. Tension in the floor
causes stress to the fasteners
which lead to squeaks.

Inadequate subfloor - 3/4"
plywood works. Why take the risk
by going light on the subfloor
to save a few dollars. Avoid 5/8"
plywood unless you are using a
3/4" solid hardwood. OSB is not
recommended as a sub-floor
material to be nailed or stapled to.

10

Poorly made product. There
are literally thousands of mills
out there making all sorts
of wood flooring products.
Always buy a recognized brand
through a dealer who knows
and recommends the product.
Sure, there are deals to be had
but understand the risks before
you place your bet. Lastly, it's
natural and acceptable for wood
floors to have the occasional
squeak. Excessive squeaking
however is not acceptable. A
repeating squeak or generally
noisy floor should be reviewed by
a professional, unbiased, certified
wood floor inspector if there is a
dispute. www.bcfca.com.
