While listed as beginner, this project requires patience and precision, especially with measuring and angled cuts. A 3-day estimate is feasible if you dedicate full days to the work, but expect it to take longer if you're new to these techniques or have limited time each day. Proper preparation and dry fitting are key to saving time and frustration.

A molding pry bar and nail puller are crucial for safely removing old trim without damaging the wall. A miter saw is highly recommended for accurate angled cuts on the new skirt boards and trim, especially for staircase stringers. Don't forget a reliable tape measure and a caulk gun for construction adhesives.

PVC trim boards, like the suggested Veranda PVC, offer excellent moisture resistance and durability, making them less prone to warping or rotting than wood. They are also easier to clean and don't require sealing before painting. However, they can be more expensive and require specific fasteners or adhesives in some cases.

The most common mistake is inaccurate angle measurement, leading to gaps. Use an angle finder or create templates from cardboard for precise cuts, especially where the skirt board meets the stair treads and risers. Always measure twice and cut once, making test cuts on scrap material if unsure.
