Size and layout
Square footage, room count, and how the rooms connect all affect the time a project takes. Open layouts with tall entry walls or stairwells often need extra equipment and time.
Surface condition and prep
Walls with cracks, nail pops, patches, or peeling paint need preparation before any paint goes on. Preparation is often the part of the project that changes the estimate the most.
Color, coats, and products
Going from a dark color to a light one can require extra coats. Product selection and availability are confirmed by the contractor, not promised in advance.
Access and occupancy
Occupied homes need more masking and furniture handling than vacant ones. Building access, parking, and elevators can also affect the plan.
Services are performed by independent local contractors. Final scope, materials, pricing, and scheduling are confirmed by the contractor.
