How to Start Flooring on an Interior Wall

Professional Floor Installation Guide: How to Start Flooring on an Interior Wall While Remaining Parallel to the Exterior Walls？

When starting any flooring, it's always best to start on an exterior wall. Exterior walls are constructed first during building and typically provide the most accurate square reference to your home's overall structure. Interior walls, on the other hand, often deviate from perfect square alignment.

Sometimes, circumstances may require starting from an interior wall. In such cases, mainly when working with materials that require permanent placement, like tiles, glue-down vinyl, or hardwood flooring, establishing a perfectly square reference line becomes critical. Once placed, these materials offer little to no room for repositioning, making your initial alignment crucial for a professional finish.

Watch our quick demonstration video to see how the Dovoh laser level helps you maintain perfect alignment with exterior walls:

Creating Your Reference Line:

To establish an accurate reference line, position your Dovoh laser level parallel to your longest exterior wall. For precision, measure multiple points along the wall to ensure perfect parallel alignment - don't just check the ends. Remember that laser lines can show slight deviation over long distances, so it's advisable to verify measurements in sections. Once your parallel line is set, use the laser's 90-degree line to establish your starting line. This perpendicular line will guide your initial row of flooring, ensuring it remains square to the rest of your home.
