Ask any wood flooring contractor what the number one problem he or she encounters on the job is, and most will answer “moisture.”  Excess moisture can cause a variety of problems with wood floors, whether the moisture originates from an environmental source, or from a flood caused by a malfunctioning appliance or unattended window.  Whatever the source of the problem, however, dealing with the results of excessive moisture in wood floors requires diligence and skill. 

In most cases, moisture problems can be avoided before they occur by practicing good installation procedures.  The first step in a successful installation is to make sure that the wood to be installed is acclimated to the job site properly.  This means that the job site needs to be as close to normal living conditions as possible before installation begins.  Once the wood is acclimated properly to the job site, it should be tested thoroughly, along with the subfloor, for moisture content.  To get accurate readings, several different pieces of wood from several different bundles should be tested. 

Often, anxious homeowners or builders will try to push wood flooring installers to skip this acclimation process because of scheduling problems.  Contractors need to be firm, and educate their customers about how wood reacts to environmental conditions.  It often is useful to keep pictures on hand that show the results of improper acclimation and moisture testing.  One look at a cupped or crowned floor, representing thousands of wasted dollars, and weeks of messy and costly repair, is often all that is needed to make the point loud and clear. 

Sometimes, despite all the installation precautions taken, moisture still can wreak havoc on a wood floor.  Faulty dishwashers, overflowing sinks, leaky pipes, malfunctioning ice makers, careless homeowners – all these problems can introduce moisture to wood floors, causing significant damage if ignored and untreated.

As a flooring professional, it’s important to know how to diagnose and repair these kinds of moisture-related issues.  This topic – Installation Failures: Tile and Hardwoods – will be discussed at length during SURFACES │StonExpo/Marmomacc Americas on Tuesday, January 24.  I look forward to seeing you there.
