Repairing Water Damaged Hardwood Floors
Water damage to hardwood floors can be caused by any number of circumstances,
from children consistently getting out of the bathtub without drying off, to a leaky dishwasher, to an outright flood from
a broken pipe. Whatever the reason for the discolored or disjointed floors, the first step to fixing the problem is always
to act quickly.
Many smaller issues are avoidable and also easily repaired. To avoid minor damage to wood floors, be
mindful of wet mopping, excess water at entryways, and overzealous settings on humidifiers. This excess water can cause crackling
of the finish or even expansion or cupping of the wood.
As soon as you notice an issue with your hardwood floor, you
need to act immediately to dry it out. If necessary, remove water from the floor with a water extraction vacuum. To dry the
flooring, open windows and use a dehumidifier or fans to pull out the moisture. Do not apply heat to the wood as this can
cause further damage. Given enough drying time, the floor may contract on its own.
There are a number of different types
of water damage that can occur to hardwood floors, and each requires a different method of repair.
A white stain or
haze typically indicates minimal damage to the surface of a hardwood floor. To remove this spot, use light pressure to buff
the finish of the wood with a mild, abrasive cleanser and a cotton cloth. Suggested cleansers include whitening toothpaste
or automotive polish.
A black stain can indicate greater issues, such as mold growth. To repair, first, make sure that
the flooring is dry. Then, tape off the area so that it is isolated during the repair process. Working just up to the edges
of your tape, remove the wax and finish using steel wool and sandpaper. Mix oxalic acid crystals in hot water and brush the
mixture onto the stained area. Let it dry, brush it off, and repeat this process until the stain is removed. Stain the area
to match the rest of the floor, and finish with sealant.
After severe water damage, it is likely that wood floors will
have to be replaced. Wood is especially susceptible to mold growth, so you need to ensure that the floor and sub-floor are
completely dry. Unfortunately, even getting these floors completely dry at the time does not mean that you may not experience
issues with mold at a later date.
If boards have cupped, popped, or cracked, this may be an indication that the sub-floor
experienced damage as well. If the sub-floor is damaged, it will also need to be replaced before you can install new hardwood
