How much time will the flooring installation project take to complete? You need to make sure that your installer can get the job done, and quickly as well. Since there is no way that you can avoid walking on the floor, this is one household project that can't be put off. This is both for the attractiveness of the home, and also for the safety of the home inhabitants.
2 - Taking Accurate Measurements
Your flooring contractor should be able to take accurate flooring installation measurements of the floor. This should seem obvious, but some installers that might want to cut corners might be tempted to "eyeball it". They might try to convince you that they can get the right measurements, just by taking at look at your floor, because they've been at it for so long. Don't fall for this.
3 - Double Checking The Measurements During The Job
A true professional will take measurements, each and every time. They should be double checking the measurements even during the job, to make sure there are no changes in the subflooring, or in the baseboards. All of this prevents against buckling and warping in the floor.
