What should you check before ordering new flooring?

The final elevation depends on the actual installation plan. The existing surface may stay or be removed. Preparation, repair, underlayment, mortar, membrane, adhesive, and the finish material can all affect the result when they are part of the selected system.

Start by documenting the current floor and the proposed stack at the places where height matters. Do not add generic layers just because they appear in an example. Use the flooring manufacturer's instructions and the project-specific plan to identify what actually belongs in the assembly.

At each affected door, look at the bottom clearance through the full swing, not only when the door is closed. Check thresholds, weather seals, floor stops and changes in elevation on both sides of the opening.

A sample stack can reveal a likely conflict early, but it does not decide the repair. The right response may involve the flooring layout, removal of existing layers, an appropriate transition, or door work suited to the door and opening. Exterior and rated doors need additional care; do not casually trim or alter them.

• Swing the door across the actual area that will receive flooring.
• Check both sides of the opening and any threshold between them.
• Identify required door work before the flooring order and schedule are locked.

An appliance may fit today but become harder to install, level, service or remove after the surrounding floor rises. The important question is the complete opening: finished floor below, counter or cabinet above, adjacent panels, required clearances, connections and the appliance manufacturer's installation instructions.

Dishwashers are an obvious example because they sit beneath a fixed counter, but the same planning applies anywhere flooring changes the usable opening or appliance position. Coordinate any disconnection, reconnection or adjustment with the appropriate qualified person and the agreed scope.

At every doorway or open connection, compare the proposed finished height with the floor that will remain. The goal is to decide how the materials, edges and elevation change will meet before the crew is improvising a transition at the end.

The answer can vary by material, direction, substrate, manufacturer requirements, movement needs and the actual difference in height. A profile that works for one floor pair may be wrong for another, so select the transition as part of the flooring plan rather than as an afterthought.

Use actual samples when available. At the door, appliance opening and adjoining floor, represent every layer that is confirmed to remain or be added. Photograph the mockup beside a stable reference and record the measured difference. If preparation thickness is still unknown, label it as unresolved instead of pretending the sample is final.

Then settle the connected scope: removal, substrate preparation, transitions, baseboard or trim work, door adjustments, appliance handling and the person responsible for each item. That gives the flooring quantity and schedule a more reliable basis.

• Door: verify the swing and threshold relationship.
• Appliance: verify the usable opening and future removal path.
• Adjacent room: verify the height difference and transition plan.
