Often I am asked if we need to remove the old flooring before installation of the new floor we are going to install. We want to look at the job site to be sure before we make that call.
Many factors come into play before making the decision to remove the old floor or overlay the existing floor, such as:
Is the old floor bonded well to the subfloor and do we think it will stay bonded for the life of the new floor?
Will the thickness of the new floor interfere with outside doors and thresholds (most interior doors can be cut if needed), what will happen to the appliances will they raise such as stove above the counter, refrigerators being raised into the cabinets above, a rise in the flooring in just one area causing other floors to be effected.
Some older floors and adhesives have asbestos, requiring professional costly removal.
These are just a few of the many things to consider before we decide to remove or overlay an existing floor.
If we are going to remove the old floor we need to schedule the time, cost and prepare for the dust and protection of furniture, cabinets and appliances. We might then need new underlayment and/or floor preparations scheduled before the new flooring can be installed.
If we have decided to install over the old flooring we might still need underlayment and/or floor preparations scheduled before the new flooring can be installed.
In short just because a floor can be installed over existing floor does not make it a good or even feasible plan.
