01
Start with the existing assembly
Document original wood, layers, and uneven subfloors
Baltimore rowhouses can contain original boards, plank subfloors, patches, and several finish layers across narrow rooms. The professional should identify what can remain, where boards need repair or fastening, and how removal, patching, leveling, and thresholds will be handled.
02
Measure the details
Price stairs, fixed elements, and material handling
Narrow stairs, landings, radiator pipes, trim, limited parking, and long carries can add labor beyond the measured floor area. Ask for the stair finish, cuts around fixed elements, transition profiles, door work, delivery route, common-area protection, and debris plan.
03
Resolve active issues first
Separate flooring preparation from water or structural work
Basement conditions and prior leaks can affect the floor system above. Point out stains, odors, soft areas, movement, or known repairs. The installer should document product-specific preparation, while active water, structural, mold, pest, or hazardous-material concerns may require another qualified specialist.
